1. INTRODUCTION

What is the Building Quality Standards Handbook?

The Building Quality Standards Handbook (BQSH or the Handbook) sets the minimum quality criteria for all Department building projects, including new construction, refurbishment and maintenance works. It has been established to ensure a high quality and consistent approach to the development of school facilities across Victoria.

The Department has acquired a considerable body of experience from the delivery and subsequent evaluation of a range of school building projects. This knowledge has been greatly abetted by the feedback received from schools and their communities. The purpose of the BQSH is to provide those involved in the design of schools with the benefit of this experience and knowledge, thereby enabling demonstrated best practice to be incorporated into building projects.

The BQSH also includes an overview of the Department’s modern school design principles and planning considerations, and provides a resource and basic checklist for those involved in Project Review and Evaluation Panel (PREP) assessments.

The BQSH provides guidance to the Victorian School Building Authority, regional offices and portfolio manager, schools, principal consultants and builders – indeed, all who participate in the development of capital works and maintenance projects.

While the BQSH describes the standard elements of a building project, it is not prescriptive in its approach and is not intended to be a comprehensive guide to all aspects of a project. Planners are encouraged to exercise their creativity within available budgets and the minimum benchmarks outlined. Similarly, materials and building practices detailed are not exhaustive, and those not covered in this document should be assessed in relation to those included. An alternative material or building practice should only be considered where it provides, without compromise, a more cost-effective solution.

This BQSH is updated regularly to reflect change and promote the latest best practice. All building projects are done in accordance with the version of the BQSH in place at the time.

All work in schools is to be undertaken in accordance with relevant building and safety regulations, codes and standards. In particular, every effort has been made to ensure that the BQSH complies with the Building Code of Australia (BCA) and applicable Australian Standards. All design, materials, workmanship, testing and commissioning shall comply with the latest revision of the BCA and relevant standards and legislation.

What is the role of infrastructure in effective education delivery?

The Department is committed to providing quality learning facilities for all students. Infrastructure is an important factor in creating positive learning environments for students, and can lead to greater student engagement, wellbeing and outcomes. This has been consistently demonstrated through international research, which has shown a link between the quality of school facilities and outcomes for students1. Studies in the United States have also found higher literacy and numeracy achievement in students learning in new or modernised facilities relative to those in non-modernised schools buildings2.

The Department is committed to providing an environment which: promotes health, engagement and wellbeing, is safe and inclusive, empowers students and builds school pride, and encourages intellectual engagement and self-awareness.

The Department understands that the strengths, needs and interests of students will vary both within and between schools, and this must be considered when planning infrastructure projects. School facilities must also be inclusive and cater for students with diverse physical, cognitive, social-emotional and sensory abilities. Early consideration should be given to how all students who may attend the school will experience its environment. Facilities need to be made more inclusive to enable every student to achieve their full potential and experience a positive learning pathway.

The Department’s commitment is reflected in its Guiding Design Principles for Inclusive Schools. These principles ensure, to the greatest extent possible, the design of educational environments that are usable by all people without adaptation or specialised design.

There are three categories under the Guiding Design Principles for Inclusive Schools.

The following Education principles capture the Department’s vision and values:1. Learners and learning are central. Planning is centred on providing learning environments

that develop the whole person - intellectually, emotionally, socially, physically and culturally. 2. Schools are community hubs. Schools and school networks are open to and provide for the

needs of all students in the community by engaging and developing partnerships with people and services.

3. Diversity is celebrated. Schools and school design ensures the inclusion of all learners by respecting and honouring diversity within the school and wider community.

4. A welcoming environment. The school environment “understands” and supports the physical and emotional health and wellbeing of all students and staff.

The Education Facilities Design principles capture the implications of the education principles for the design of new and updated facilities:

5. Local schools are accessible to all. Design facilities to maximise accessibility to all members of the community. Consider locations which are easily and safely accessed by the greatest number of students, by sustainable modes of transport.

6. Promote a collaborative approach to provision planning within school networks. Identify a number of schools in each network with a specialist focus area; ensuring students with specific needs are well accommodated at a school somewhere within their local community.

7. Co-locate facilities that are tailored for students with disabilities within mainstream schools, ahead of other options. Design for student interaction and allow for graduated levels of support e.g. room for aides and flexible spaces that are sensitive to the needs of all learners. Siblings can travel together to a single local school where all learning needs are welcomed and met.

8. Create facilities that offer a variety of spaces to meet all needs. A choice of indoor and outdoor spaces is provided to support individual and group learning and engagement needs. Microenvironment design takes into account the needs of students with a range of disabilities and supports maximum inclusion and participation by all students.

9. Design facilities that are adaptable for changing purposes. School facilities are capable of being used for different organisational models and by diverse students in different ways over the life of the buildings without requiring significant modification.

10. Design schools to serve future communities. School facilities are designed and built to serve diverse communities for 30–50 years or more and can be reconfigured for changing needs.

The following Universal Design Principles, which are discussed in more detail in Section 3, are also supported by the Department:

1. Equitable use. The design is useful and marketable to people with diverse abilities.2. Flexibility in use. The design accommodates a wide range of individual preferences and

abilities.3. Simple and intuitive use. Use of the design is easy to understand, regardless of the user’s

experience, knowledge, language skills, or current concentration level.4. Perceptible information. The design communicates necessary information effectively to the

user, regardless of ambient conditions or the user’s sensory abilities.5. Tolerance for error. The design minimises hazards and the adverse consequences of

accidental or unintended actions.6. Low physical effort. The design can be used efficiently and comfortably and with a minimum

of fatigue. 7. Size and space for approach and use. Appropriate size and space is provided for approach,

reach, manipulation and use regardless of user’s body size, posture or mobility.



1.1 Key Resources

In addition to the Handbook, those involved in the development of capital works and maintenance projects should also refer to the following key resources.

Project Management Framework

The Project Management Framework provides schools and their communities, Project Managers, Principal Design Consultants, Cost Managers and other consultants with the overall framework within which Capital and Maintenance projects must be delivered.

The PMF has been developed to ensure consistency in the planning, delivery, process and governance across all projects; and replaces the Capital Works Procedures Manual, December 2011.

The PMF is to be used in the delivery of Capital and Maintenance projects with a value greater than $200,000; and is applicable to all school-led, partnership and Department-led projects.

Department of Education and TrainingSection 2 – Legislative Requirements

2. LEGISLATIVE REQUIREMENTS

All design, materials and construction practice must comply with the latest version of the Building Code of Australia, the Building Act 1993, Building Regulations 2006 and relevant Australian Standards and legislation.

The Planning and Environment Act 1987 and the Planning and Environment Regulations 2015 may also be applicable.

The Dangerous Goods (Storage and Handling) Regulations 2012 require the design of laboratories to be in accordance with Australian Standard AS 2982 – Laboratory Construction.

When designing storage areas, the Occupational Health and Safety Regulations 2007 must be taken into consideration.

Workplace health and safety, especially in relation to hazardous materials and asbestos, are crucial considerations (refer to Section 11 – Workplace Health and Safety for more detail), and the Safe Drinking Water Act 2003 and Disability Discrimination Act 1992 must also be borne in mind when developing school facilities.

Principal consultants must design facilities which meet the legislative requirements. In addition to these requirements, consultants need to consider the needs of the school community. Section 3 Modern School Design – An Overview refers to the design principles to be considered when designing school facilities, including the importance of Universal Design.

2.1 Bushfire Provision – Ministerial Direction No. 3

Ministerial Direction No. 3 – Bushfire provisions for buildings of a public nature (MD3) came into effect on 1 February 2010 for all projects requiring a building permit.

In relation to the design process for buildings of a public nature, including schools, the Ministerial Direction aims to ensure that government and public authorities undertake bushfire attack risk assessments based on methods described in AS 3959-2009 Construction of buildings in bushfire prone areas. Dependent on the site and its assessed level of risk, the design of new or refurbished facilities must account for this potential threat.

Those working on Department projects need to be fully informed of these requirements. To achieve this, consultants will need to have qualified staff or be able to access suitably qualified practitioners.

All projects progressing to construction must comply with the requirements of the Ministerial Direction and AS 3959-2009.



2.2 Victorian Industry Participation Policy (VIPP)

Further to the requirements of the Department of Education and Training, users of the Handbook should also be aware of the Victorian Industry Participation Policy. The VIPP aims to boost local employment and business growth by expanding market opportunities for Victorian companies.

The VIPP requires government departments and agencies to consider competitive local suppliers, including SMEs, when awarding contracts valued at:

► $1 million or more in regional Victoria or► $3 million or more in metropolitan Melbourne or for state-wide activities.

For further information, visit the VIPP page on the Department of Economic Development, Jobs, Transport and Resources website http://www.dsdbi.vic.gov.au/projects-and-initiatives/victorian-industry-participation-policy

It is recommended that specified fittings and equipment be sourced, where possible, from Australian suppliers in order to assure availability of replacement parts and facilitate maintenance.

3. MODERN SCHOOL DESIGN – AN OVERVIEW

The Department of Education and Training’s vision for school design reflects 21st century thinking about pedagogy and space. New spaces must be adaptable and support a variety of teaching and learning approaches, from team teaching to one-on-one lessons, and encourage collaboration between students and teachers.

Those involved in the design of schools should consider the following design principles to ensure schools develop environments and buildings that are safe, sustainable, durable and aesthetically pleasing as well as functional and fit for purpose.

Design Principles to Consider

Universal Design

The Department supports the concept of universal design. We believe that it constitutes best practice in the delivery of environments that ensure access and participation for all.

A working group of architects, product designers, engineers and environmental design researchers at the Centre for Universal Design, North Carolina State University, have created seven universal design principles to guide the concept’s implementation. These principles have been widely accepted internationally, and the Department supports their inclusion in school design.

All principal consultants engaged by the Department for new school or upgrade projects must have regard to these seven universal design principles. Many of these are already taken into consideration by designers when complying with the Disability Discrimination Act 1992 and related standards such as, the Disability (Access to Premises- Buildings) Standards.

While there may be some overlap, the universal design principles go beyond these minimum standards and provide greater guidance and direction on how to design facilities that better accommodate students with varied needs and abilities. The seven universal design principles are outlined below:

1. Equitable useThe design is useful and marketable to people with diverse abilities.Examples:

Having a ramp integrated with stairs, both under cover. Outdoor seating with different arm and back configurations and at different heights so

that it may be used by a variety of people. Variety of different spaces to accommodate students with a range of disabilities.


http://www.education.vic.gov.au/school/principals/infrastructure/Pages/design.aspx


2. Flexibility in useThe design accommodates a wide range of individual preferences and abilities.Examples:

Adjustable work benches. Bins operable by one hand to accommodate left and right handed students. Water taps that are easy to grasp and operate. The creation of spaces that can be set up and used in a variety of ways

3. Simple and Intuitive useUse of the design is easy to understand, regardless of the user’s experience, knowledge, language skills, or current concentration level. Examples:

“Wayfinding” (referring to the ways in which people orient themselves and navigate from place to place) with tactile information.

Colour coding on walls and doors. Continuous pathways (no breaks) to ensure easy travel between buildings. Avoidance of overhanging structures to facilitate unobstructed access for vision

impaired students who may use a cane.

4. Perceptible InformationThe design communicates necessary information effectively to the user, regardless of ambient conditions or the user’s sensory abilities. Examples:

Signage at height visible to wheelchair users. PA and emergency communication systems having both auditory and visual cues. Glazing and placement of windows to avoid glare for vision impaired students. Room acoustics designed to assist hearing impaired students. Social scripts or pictorials to communicate room function. Adjustable lighting to assist vision impaired students..

5. Tolerance for errorThe design minimises hazards and the adverse consequences of accidental or unintended actions. Examples:

Column detailing and placement to assist people with vision impairment in differentiating columns.

Floor at equal level where possible to ensure there is no tripping hazard. Edge definition for steps.

6. Low Physical Effort



The design can be used efficiently and comfortably and with a minimum of fatigue. Examples:

Loop handles on toilet doors. Doors that automatically open for students with wheelchairs or staff carrying heavy

goods. Controls, such as light switches and thermostats, at heights easily accessible for students

in wheelchairs.

7. Size and Space for Approach and UseAppropriate size and space is provided for approach, reach, manipulation and use regardless of user’s body size, posture or mobility. Examples:

Appropriate circulation space in toilets suitable for students in wheelchairs. Floor surfaces comfortable for students with differing sensory abilities.

Additional considerations Universal design should be given primary consideration. Aesthetic design features

should be avoided if they will have unintended consequences for the accessibility of the school.

Principal consultants should try and create spaces that are non-threatening and non-distracting for students with cognitive disabilities.

Consider placing items, such as lamp posts and bins, at regular intervals to provide sensory cues.

Consider placing essential facilities and specialist buildings on the ground floor and near the entry point to the school, so that they may be easily accessible by all.

Principal consultants should consider footpath transition from schools to public spaces by placing accessible pathways which extend beyond school grounds.

Principal consultants should consider installing reinforced ceiling, support structures and rails for students requiring hoists.

Hand driers can affect students with noise sensitivity and consideration should be given to noise-reduced hand drying options.

Future Use of Learning SpacesBuilding designs should enable schools to: evolve over time, in their current or a reconfigured form, to accommodate changing

pedagogical approaches, models of education, changing enrolment numbers and community linkages; and

be flexible in how the school and community will use the facilities in the future.

Classrooms – Flexibility of Learning Spaces



Classrooms should be designed to: be flexible and functional to support contemporary learning and teaching practices with a

focus on active, student-centred learning; allow students to work independently or in small groups within the classroom; provide breakout areas to allow students to work independently, with peers, or on a one-on-

one basis with the teachers; allow teachers to operate effectively from any location in the room; allow for team teaching approaches e.g. movable walls between spaces, and flexible and

adaptable furniture; and incorporate sliding doors and operable walls to allow home-bases to exist in a single

contained form, when acoustic, physical or visual separation is needed.

Teacher Support Spaces

Building designs should enable teachers to: plan collaboratively with colleagues, prepare class materials or write reports when not in

their classrooms; access learning resources near their work spaces, and have space for storing and viewing or

reproducing digital and hard copies; have discrete spaces available for group meetings and interviews with parents; and secure personal resources and effects.

Student Support Spaces

Building designs should enable students to: meet socially or work with peers; securely store their personal effects, bags, coats, books and sports gear; and store and review information such as books or electronic resources, and reproduce digital

and hard copy information.

Information Communications Technology (ICT)

Learning spaces should:

support new ways of learning and linking students to the broader community and to the world;

provide easy access to computers and other electronic resources; incorporate wireless technology, interactive white boards, data shows or other multi-media

and laptops; and be flexible to adapt to changes in technology.



Outdoor Learning Spaces

New building designs should incorporate outdoor learning spaces that are easily accessible to assist with meeting individual and social needs of students and provide greater options for teachers.

Internal Environmental Quality

Learning environments should create physical and emotional health and well-being, and promote positive social interaction between all students and staff.

Designs should incorporate:

good use of natural light as well as controllable lighting that allows for daylight harvesting; good ventilation and airflow; good internal acoustics and minimisation of external noise; insulated ceilings and walls, creating thermally efficient internal environments; and passive and active features to maintain a comfortable indoor temperature.

Environmentally Sustainable Design

Incorporate sustainable environmental principles in the design, construction and operation of buildings in schools to maximise energy and water efficiency and minimise waste. The following elements should be considered:

building orientation for optimum passive heating and cooling performance; landscaping choices for optimum passive heating and cooling performance; highly efficient/low energy consumption heating, cooling and lighting systems; water saving and low usage devices, especially toilets and hand basins; rain water collection tanks to harvest water for use in the schools systems, including toilets

and irrigation; and areas within each block where recyclable materials (glass, paper, etc.) can be stored before

their removal to the school’s central recycling area.

Aesthetics of School Design

Visual Appeal

Incorporate characteristics of high quality design that inspire and create a sense of belonging among students and the broader school community.



Culture and Surrounds

Each school community has its own unique culture, surroundings and natural environment that can be incorporated into the design, including: the cultural diversity of the school’s community or its surrounding environment; surrounding street network, traffic and pedestrian infrastructure; nearby community or recreational facilities; and the urban form and character of the local environment.

Community and Safety

Connection to Community

New school designs have the ability to connect learning with the community, reaching beyond the confines of the classroom to bridge the gap between community and school.

Designs should consider: the broader community context to foster joint use arrangements, sharing and out of hours

community access wherever possible, e.g. as community halls or meeting spaces, sports fields and performing arts centres; and

allowing the community to support student learning by accessing part of the school for lectures, demonstrations, presentations or working with teachers.

Safety and Security

Designs must consider the safety and security of all students, staff and visitors while also minimising security risks for buildings and other school assets.

Buildings should be designed to: adhere to occupational health and safety standards; provide safe access to facilities including toilets; allow teachers to easily monitor or supervise all areas of the school; provide good lighting around and in new buildings, including night lighting for areas used

after school hours; allow administration areas to be prominent and main point to control access to the school; provide safe access to car parks after hours; where possible, compartmentalise facilities for out of hours use; and minimise roof access.

4. PLANNING

4.1 Introduction

The development or upgrade of new school facilities involves a range of inputs including Departmental planning procedures and facility schedules, relevant building and safety regulations, codes and standards, school and community aspirations, local knowledge and design imagination.

It is essential that the resulting facilities address both today and tomorrow’s educational programs as well as flexibility, accessibility, energy efficiency and low maintenance requirements.

The following sections outline key planning considerations in the design of school facilities. The sections also contain advice gained from the Department’s considerable experience in delivering a range of school building projects and through post occupancy evaluations of delivered facilities.

4.2 Departmental Planning Process

The Departmental planning process for capital and maintenance projects is outlined in the Department’s Project Management Framework (PMF).

The PMF outlines the procedures for each of the key phases for the delivery of capital and maintenance projects.

The PMF also outlines the three management options available to schools for the delivery of their project: School-led; Partnership with DET and DET-led.

Project Management Framework

https://edugate.eduweb.vic.gov.au/sc/sites/Infonline/Policies%20Guidelines%20and%20Procedures /Project%20Management%20Framework%20(July%202014).pdf (access restricted to Department personnel, school users and registered users with an Edumail account and pin number).

4.3 Space and Area Entitlements

Space and area entitlements for school facilities are broadly defined within the Facilities Schedules listed on the School Infrastructure Principal Consultants section of the Infrastructure and Sustainability Division website (https://edugate.eduweb.vic.gov.au/sc/sites/Infonline/default.aspx) (access restricted to Department personnel, school users and registered users with an Edumail account and pin number).

These schedules are used when planning a new school or when upgrading existing schools.



They outline a standard but they also offer flexibility within budgets provided. Given an adequate accommodation of core curriculum needs and student numbers, spaces can be arranged and modified to suit the particular profile of a school.

4.4 School Design Considerations

The following sections outline key considerations in the design of modern school learning spaces and school sites.

The information and guidance contained in this section has been gained through the Department’s extensive experience in delivering a range of infrastructure projects, and through post occupancy evaluations of delivered facilities.

4.4.1 Anthropometrics

Buildings and fittings should be designed or selected so as to be suitable for both students and adults. AS/NZS 1429.1 and AS/NZS 1429.2 provide guidance.

4.4.2 Accessibility

Access and Interior/Exterior Connection

Access and egress should:

► be easily defined and located;

► be on a single level;

► be at least to standards specified in AS 1428 Design for access and mobility and AS 2890 Parking facilities; and

► enable safe, equitable and dignified access to and emergency evacuation from all facilities.

External areas should reflect the activities of adjoining buildings.

Provision for All Occupants

Accessibility and amenity of the school and its site must be available to all authorised occupants, including people with disabilities, whether students, staff, parents or other visitors.

Required accessibility and amenity are stipulated in the Building Code of Australia and Disability (Access to Premises – Buildings) Standards 2010.

The provisions of the latest versions of the following Australian Standards must also be followed:

► AS 1428 Design for access and mobility

AS 1428.1: General requirements for access – New building work.



AS 1428.2: Enhanced and additional requirements – Buildings and facilities.

AS 1428.3: Requirements for children and adolescents with physical disabilities.

AS/NZS 1428.4.1: Means to assist the orientation of people with vision impairment - Tactile ground surface indicators.

AS1428.5: Communication for people who are deaf or hearing impaired.

► AS/NZS 2890.1 Parking facilities – Off-street car parking.

► AS 1735.12 Lifts, escalators and moving walks - Facilities for persons with disabilities.

► AS/NZS 2890.6 Part 6: Off-street parking for people with disabilities.

4.4.3 Flexibility

Flexibility should be a key factor in design solutions. Buildings need to offer schools flexible options for daily use as well as an opportunity for simple refurbishment or remodelling as future needs change. Options to consider include activity areas grouped or separated with operable walls (or other moveable partitioning) as well as the use of light and mobile furniture.

4.4.4 Design Relationships

Successful space planning pursues an efficient combination of teacher resources and organisation, student grouping and teaching/learning methods. A range of issues and relationships need to be considered in achieving this, as outlined below.

Intelligent space planning will reduce the cost of complying with the recommendations of the Building Quality Standards Handbook and minimise occupant concerns and complaints. Spaces with opposing acoustic requirements, for example, should be located as far apart as practicable, while open-plan and small-group areas should be purposefully arranged in accordance with teacher, student and curricula needs.

Activities

The relationship between activities and their compatibility and flexibility should include:

► separation of noisy and quiet areas;

► position of multi-purpose/physical education facilities to oval, hard court and car park;

► position of administration to car park and main school entry; and

► central location of toilet blocks.

Subsections of the School

The relationship between subsections of the school should cover:

► junior/middle/senior school organisation;

► general purpose/specialist facilities;



► departments/faculties; and

► indoor and outdoor learning spaces.

Buildings and Site

The relationship between buildings and the site should cover:

► buildings and open space;

► slope and contours;

► flood levels and overland drainage;

► bushfire attack levels of each building on site;

► services;

► signposting;

► pedestrian and vehicle movement;

► deliveries;

► efficient removal of recyclables and waste; and

► emergency access.

Note: useful consideration of site-related issues requires the early provision of contoured site plans showing the cross-fall and points of stormwater discharge.

School and Environment

The relationship between the school and the environment should account for:

► vegetation;

► flood levels;

► soil conditions;

► climate/microclimate (design should be compact to minimise external travel in areas of high exposure);

► neighbouring properties;

► solar access; and

► capture and use of rainwater.

School and Community

The relationship between the school and its community should include:

► out-of-hours use of facilities by students, families and other visitors; and

► noisy activities, including vehicle access and car parking, affecting adjacent properties, and including out-of-hours use.



4.4.5 Image and Aesthetics

Design should take into account the role of the school in its community. Features should include:

► an obvious point of entry and address;

► avoidance of extreme architectural features as solutions;

► sign posting and organisation to promote ease of access and movement within;

► appropriate use of colour schemes; and

► acknowledgement of surrounds and community.

4.4.6 Technology

School buildings should, where possible and appropriate, facilitate the use of current and future technology and promote the use of modern materials and. Among the things to consider:

► cabling must be installed with a view to future flexibility (Refer to Section 9 – Communication Services);

► cabling and equipment must reflect current standards but have the capacity for change or expansion in future services;

► loose furniture may be preferable to built-in furniture;

► services should promote ease of connection and disconnection;

Information and Communications Technology (ICT)

Wireless communications is not a replacement for a structured cabling system. It complements the cabling system and adds some flexibility.

High-speed broadband access will be delivered to every site.

ICT requirements are described in more detail in Section 9. Additional guidelines on the design and installation of ICT in schools are referenced under that section.

ICT facilities may need to be adapted to suit individual needs of some students, staff and visitors (e.g. people with disabilities).

Placement of Computers

As noted in post-occupancy evaluations (2005), computers have been successfully located in:

► the library as a resource centre/information technology zone which also functions as a conference facility and discussion space;

► pods to allow supervision;

► general-purpose classrooms to provide accessibility for use by students; and



► information technology zones in travel space/corridors, with vision panels from adjacent classrooms to provide supervision

Low-level or height-adjustable computer desks should be considered to enable use by a broad range of users.

4.4.7 Equipment and Fittings

Equipment and fittings should be located in a manner that ensures safe use and circulation.

Inadequate “domestic” standards applied to the selection of fixtures and finishes, for example, have included poor installation of locks and latches (endangering fingers), poor location of fixtures (fire hose reel cupboards in the path of student travel), unsatisfactory toilet and sanitary fixtures, and inferior durability of benches (both joinery and surfaces) in technology rooms, home economics and science laboratories.

The provision of display boards and display spaces is particularly important in primary schools. A proportion of these should be low enough to be comfortably readable by students, staff, parents and visitors in wheelchairs (refer AS 1428.2 and AS 1428.3). A lack of display space has been found to result in windows being used as display areas.

4.4.8 Storage

Storage spaces should be directly accessible from activity spaces. The sharing of storage between spaces may also enable the creation of larger, more useful spaces. When designing storage areas, the Occupational Health and Safety Regulations 2007 must be taken into consideration. This is particularly important in designing archive storage areas where preference should be given to small size archive boxes.

4.4.9 Acoustics

Designers must ensure that the acoustic performance of the building meets appropriate standards and should consider the following issues:

► control of sound transfer between spaces;

► control of room reverberation (echoing) within spaces; and

► control of ambient noise levels arising from mechanical plant, equipment or external noise (such as transportation).

These issues can be addressed by considering:

► the construction of internal walls that divide rooms;

► the type and positioning of doors;

► the surface treatments of walls, floors and ceilings within learning spaces as well as in areas adjoining learning spaces;



► the treatment and/or design of air ducts or other ventilation paths that connect spaces; and

► the attenuation by design of noise intruding into learning space from mechanical services, other equipment or external sources such as traffic, rail transport, aircraft or rain-fall onto the roof of the building.

At the very outset, floor planning should consider acoustic design requirements. Spaces with opposite acoustic requirements should be located as far apart as is practicable. Where open-plan teaching spaces are proposed, dedicated quiet rooms or pods should also be included to cater for small groups needing acoustic separation from the main group.

Appropriate design standards and methods are provided in Section 6.11.

4.4.10 Provision for Relocatable Buildings

The relationship between buildings and the site should include consideration of the placement of relocatable buildings.

Planning should include provision of space for relocatable buildings, and be mindful that the actual number of such buildings will fluctuate as school needs vary up to the provided peak enrolment.

Planning of services for relocatables is required to enable economical connection to power, water and drainage.

Orientation, outlook, adjacent open spaces, circulation routes, paths, covered ways, etc., need to be considered for relocatable buildings just as for permanent buildings.

Aesthetic aspects, including the provision of connecting and unifying treatments, need to be considered so that these buildings are a part of the school rather than an unconsidered afterthought.


Post-occupancy Evaluation Findings – Acoustics

Problems found with acoustics include a lack of sound separation between spaces caused by:

sound transfer through unlined ducts;

gaps at the external wall/partition interface; and

general purpose classrooms (GPCs) located beneath first-floor physical education rooms with inadequate isolation.

Lack of attenuation within spaces caused by:

hard surfaces; and

insufficient acoustic treatment.

Recommendations to overcome these issues are discussed in Section 6.11.

23


Requirements for installation and removal of buildings, including truck and crane access, also need to be considered.The external design should provide a local presence and provide a focal point commensurate with its environment.

Elements of successful external design feature:

► borrowed elements from local landscape to express context and heritage issues;

► large-volume buildings broken down through the innovative articulation of generic and cost-effective materials;

► ESD-driven design initiatives, sun shading devices, pop-up roofs for natural light and night purging, etc.; and

► integration of relocatables with permanent structures, providing physical connections through corridors or other structures, and adding external treatment to relocatables to blend them with the main group of buildings.

Successful internal designs incorporate material finishes which reflect the functional requirement of the space (for example, an industrial ambience for technology spaces).

4.5 Shared Use of School Facilities

The shared use of facilities is promoted by the Department as an option available to schools. General information and guidelines are provided on the School Infrastructure website at http://www.education.vic.gov.au/school/principals/infrastructure/Pages/propertyshare.aspx

4.5.1 Adjacency of Spaces and Community Use

Adjacent locations for facilities with complementary functions should be considered. For example, the location of a gymnasium, performing arts facility, or library (as resource centre/IT zone/ conference facility) adjacent to a dining area, canteen or food technology classroom allows the development of a cafe facility for out-of-hours performances, student personal development programs, and wider community use.

4.5.2 Competition Grade Sporting Facilities

The design standards set out in Section 6 - Substructure, Superstructure & Finishes apply to sporting facilities focused on providing schools with flexible indoor and outdoor spaces able to be used for school-level sport, performances and assemblies as well as various curriculum, general play and dispersal activities. Further to these school level sporting facilities the Department regularly works with partners, generally local councils and other community groups, to co-invest in the delivery of competition-grade facilities. For those schools building competition-grade sporting facilities, refer to Appendix 4 Competition Grade Sporting Facilities for the required design standards.


http://www.education.vic.gov.au/school/principals/infrastructure/Pages/propertyshare.aspx


4.6 Security and Safety

Schools must provide a safe and secure environment for students, staff and visitors, including parents and service personnel.

The following design considerations overlap with occupational health and safety (OH&S) and accessibility for people with disabilities. In relation to intruder-detection systems, contact the Department’s Security Services Unit.

In terms of security, good design should consider:

► logical street access directing visitors to administration facilities and permitting the supervision of entries;

► building design and choice of finishes that discourage vandalism and abuse;

► avoiding nooks and crannies;

► providing night lighting/sensors at access points;

► lighting to cover after hours usage;

► compartmentalising facilities for out-of-hours use;

► well-placed external PA speakers;

► design which promotes good supervision of all areas by teachers;

► safe access to toilets during classroom hours, lunch and recess times, and out-of-hours; and

► safe access to car parks out-of-hours.

In terms of safety, good design should consider:

► fitment design ensuring smooth corners and appropriate location;

► adequate ventilation;

► window placements and glass, avoiding the positioning of operable windows in traffic areas (glazing should accord with the Building Code of Australia) ;

► minimising and controlling roof access;

► on-site traffic management;

► avoiding differences of level across the site or, if this is not possible, ensuring that changes of level are dealt with in an appropriate manner (refer also to the Building Code of Australia);

► providing non-slip surfaces in internal and external circulation areas as per the Building Code of Australia and Australian Standards;

► asthma and allergy minimisation; and

► stretcher access to first-aid locations.

Safety in design is part of the occupational health and safety requirements (refer Section 11).



Useful security hints and practical advice can be obtained from the Department’s Security Services webpage: (https://edugate.eduweb.vic.gov.au/Services/Schools/Infrastructure/Emergency/Pages/default.aspx) (Note: this site requires an Edumail user ID and password for access.)

4.7 Environmental Sustainability

Energy-conscious buildings lead to improved facilities operation, better staff and student performance, reduced operating costs, and lower greenhouse gas emissions.

In terms of environmentally sustainable planning and energy management, Victorian school design responds to local environmental conditions and reflects a commitment to minimising greenhouse gas emissions. Architects and builders are essential partners in the development of facilities which achieve user comfort through informed planning and sustainable construction practices.

Building practitioners and users of this Handbook should be mindful of matters related to environmentally sustainable planning and energy management. National best-practice is linked to the Green Star – Education Tool developed by the Green Building Council of Australia http://www.gbcaus.org/

For additional resources, practitioners and consultants are also advised to visit:

► The Building Commission http://www.buildingcommission.com.au

► Sustainability Victoria http://www.sustainability.vic.gov.au

The following sections outline passive environmentally sustainable design aspects that should be considered in the planning and design of school buildings.


Post-occupancy Evaluation Findings – Security

Different approaches to security employed in projects reviewed in post-occupancy evaluations include:

► extensive use of glass between spaces to provide visual supervision (especially in primary schools);

► surveillance cameras (the Department’s Emergency & Security Management Unit approves school requests for CCTV, and schools fund this form of surveillance);

► high fences (the location of these can be selective rather than enclose the whole site, e.g. such fencing can exclude car-parks, ovals and entry areas); and

► community use of facilities out-of-hours to provide increased surveillance.

Other possible approaches to security include the layout of buildings to enhance visibility, and landscaping and lighting to avoid “lurking places”.

4.7.1 Orientation

A prime consideration should be the placing of all buildings with their long axis in the east/west direction in order to maximise north facing facades and minimise east/west facing facades (this must be addressed in the Masterplan and Schematic Design reports).

To further reduce the problem of overheating in summer, window design should incorporate adequate shading (refer to Section 6.6 – External Windows).

4.7.2 Site Planning for Airflow Control

Consider the use of airlocks and placing external doorways on the east side of buildings to minimise indoor wind gusts and draughts. The size of airlocks should accord with the Building Code of Australia.

When planning for single-sided or cross natural ventilation for use in summer, consider openings on the south face or from shaded/sheltered areas to avail of the cooler air.

Ventilation openings should be onto areas that are as dust-free as possible.

Consideration should be given to prevailing weather and seasonal climate to limit the entry of such conditions as hot northerly winds.

Noted causes of poor performance in relation to natural ventilation and thermal comfort include:

poor plan layouts which hinder cross flow ventilation;

closed up corridor spaces with low ceilings;

poor sun shading; and

operable shading devices and windows provided but difficult to adjust or open.

4.7.3 Surface Area of Buildings

Consider reducing the external surface area of buildings by joining spaces together.

Consider reducing the area of windows, but to a point where they can still perform the functions of providing daylight, view and connection to the outside.

4.7.4 Overshadowing

Ensure that the north facade of a proposed building is not overshadowed by other buildings to the north by setting it back (south) at a distance that is twice the height of the obstruction. Ensure the proposed building does not overshadow any existing building to the south by placing buildings twice their height north of any existing building.



Shading diagrams should be prepared to accurately establish the extent of shadowing by adjoining features.



4.7.5 Daylight

The layout of buildings should facilitate the daylighting of rooms. Because adequate levels of daylight via windows typically penetrate only three metres into a building, consider the use of shaded skylights or clerestories to provide additional illumination.

The size and orientation of skylights and clerestory windows, however, should be carefully considered so as to limit overheating and glare. All skylights and clerestory windows should be shaded from summer insolation.

Daylighting and the minimisation of artificial lighting must be addressed in the Schematic Design report.

Sunlight penetration of windows and skylights should be checked by means of insolation calculations, using appropriate software.

4.7.6 Zoning

Provide doors or airlocks to separate areas that are heated/cooled from areas that are not heated/cooled. Provide doors to isolate two-storey spaces (such as stairs) from heated/cooled spaces. Zoned areas possess a thermal advantage over open plan inasmuch as heating and cooling systems need only operate in areas that are occupied.

Airlock and doorway sizes should accord with the Building Code of Australia.

Zoning must be addressed in the Masterplan report.

4.7.7 Shelter

Outside areas should be sheltered, where possible, from winter and summer winds, and shaded from the sun from September to April (Terms 1 and 4). These considerations must be addressed in the Masterplan report.

4.7.8 Recycling

Designs should consider providing an area in each block where recyclable materials (glass, paper, etc.) can be stored before their removal to the school’s central recycling area.

School should be encouraged to develop a reuse and recycling strategy.



4.7.9 Landscaping

A well maintained, functional and attractive school site can enhance the self-esteem of all users, foster sociable behaviour and facilitate performance.

All aspects of site development, including landscaping, should be reflected in a school’s masterplan. Landscaping should not be dealt with in isolation but form an integral part of the overall development.

The site design should also consider site drainage and the sensitivity of the site surface and sub-surface drainage to regular maintenance.

Every effort should be made to retain existing trees. To achieve this, a proper survey should be carried out of all significant trees and site features prior to any masterplanning.

Deciduous trees to the north (or evergreens set back a distance twice their height), and evergreens to the east and west can block summer morning and evening sun if external blinds are not provided. The maintenance costs of deciduous trees should be considered.

The development of school grounds should satisfy the following major goals:

► provision of a safe, manageable, pleasant and ecologically responsible outdoor environment;

► provision of areas and facilities which meet outdoor curriculum requirements;

► provision of areas and facilities which meet outdoor play, assembly and physical education requirements; and

► consideration of ecologically sustainable performance related to landscape irrigation and water efficiency, transport design and cyclist facilities, and recycling storage areas.

Refer Section 10 – Site Works & School Landscaping for greater detail.

4.8 Energy Planning

Energy should be considered at the masterplanning stage or before. It should not be left until the schematic design stage or later. Energy planning should involve all parties associated with the development of a school. It is not just an electrical or mechanical issue. If school design is good, an assumed dependence on components such as airconditioning is not automatic. Beware of standard solutions.

► design should consider the use of solar energy where appropriate and cost effective;

► design should consider solar hot-water (schools are currently eligible for Victorian Government grants that help reduce the cost of solar hot-water installation);

► control technology should be included where centralised heating and domestic hot-water plant are specified;

► timers/sensors should be installed where artificial lighting is used;



► heating controls should allow zoning, individual control and auto shutdown;

► sustainable products should be used where both appropriate and cost-effective, including those materials and products made with recycled content and recyclable at end-o-life (this needs to be addressed in the Design Development report); and

Building regulations will require all new work to comply with Part J of the Building Code of Australia which includes achieving solutions in respect to:

► building fabric;

► external gazing;

► building sealing;

► air movement;

► airconditioning and ventilation systems;

► artificial lighting and power;

► hot water supply; and

► access for maintenance.

4.8.1 Energy Engineer

It is recommended that an energy engineer be engaged as part of the design team to provide specialised energy advice and design assessments.

4.8.2 Energy Audit

Undertake an energy audit of existing premises, if appropriate, to establish existing energy use patterns which can then be addressed in new design. The energy audit must be addressed in the Masterplan report.

4.8.3 Energy Design Process

Incorporate into the existing design process the following steps:

► hold a project meeting with all stakeholders to agree to goals, budgets, and energy and financial measurement methods;

► review energy performance whenever cost plan is reviewed; and

► treat mechanical and electrical design and building fabric design as one exercise.

4.8.4 Computer Modelling

Consider using computer modelling to determine the effectiveness of or the adjustments necessary to daylight and natural ventilation systems.



4.8.5 Testing and Commissioning

Energy efficient equipment should be specified. Where appropriate, testing and commissioning should confirm this performance.

Testing and commissioning should include the handover of accurate and detailed building and systems records and operations directions. Such documentation should not only set out details of the installation and its energy-efficient operation but clearly record all design assumptions and capacities in order to facilitate future modifications and building adjustment.

4.8.6 Maintenance Strategy

School councils should be provided with a ten-year maintenance strategy for all plant and equipment.

The maintenance strategy should include a fine tuning of plant to the building’s actual occupancy and operation. It should also demonstrate how maintenance will be provided. For outsourced maintenance, some degree of energy performance outcome should be built into the contract.

A meeting should be held with school staff, the consultant and the mechanical and electrical contractors to “hand over” the maintenance documents and “walk through” the project, explaining any required actions.

The maintenance strategy should include site maintenance – including cutting of swales, cleaning of stormwater (SW) pits and drains, clearing of gutters and downpipes etc.

The strategy should recognise that these tasks can fall back in order of priority. The design should consider the performance of stormwater and roof drainage if it is not maintained. A ‘belts and braces’ approach may be appropriate that provides secondary relief in the event of the primary barrier to inundation failing, e.g. buildings should not flood even if gutters and downpipes fill with leaves; a courtyard should not flood back into the buildings if the storm-water drains become clogged.

No area should depend upon a single drainage point or single kind of drainage / drainage system.

4.8.7 Selection of Office Equipment

Office equipment can consume up to 10% of the total energy used in a building. Equipment should be selected with a low energy rating sufficient to perform the task required.

4.9 Special Factors

Special factors which may lead to additional costs to a building project are described in detail in Section 5 – Special Factors.



4.10 Construction Planning

The following sections outline key construction planning considerations.

Planning needs to allow for a staged implementation of works within a single project. Stages should reflect available funding as well as the need to enable schools to continue operating without undue disruption to the learning environment. Service provision in the initial stage should provide for total development requirements.

4.10.1 Economy and Cost Effectiveness

Building and site development should incorporate both economic and cost-effective construction as well as operational and maintenance considerations. Factors include:

► appropriate internal volumes that reflect purpose and the scale of user;

► robust and durable materials and finishes;

► structure, including the: provision of regular building shapes,: provision of simple roof forms that promote effective drainage,: consideration of two storey buildings only when site constraints make single storey

buildings less cost effective,: grouping of areas, particularly those that require mechanical services,: keeping of circulation space within scheduled allowances,: placement of structures on site in close proximity to services,: use of cost-effective structural solutions to site constraints;

► location on site so that: buildings are positioned in close proximity to services and site access points,: buildings are grouped to minimise circulation requirements,: site conditions (including soil, rock, vegetation, flood levels, and contours) are considered,

with buildings situated to minimise cost penalties associated with slope or rock and to maximise the use of features such as existing vegetation;

► consideration of a landscaping component in the total design strategy;

► planning to allow for the potential staging of works and in such a way that the duplication or redundancy of facilities and services provided in earlier stages is avoided;

► siting relocatables with consideration for their integration among other facilities and/or future removal;

► siting relocatables with their windows facing north and south;

► planning of consecutive stages (of new secondary colleges) adjacent to one another for ease of access (i.e. less external travel) and the minimisation of open spaces which require landscaping but may form construction areas in future stages;

► keeping toilet allocations for new primary schools to no more than two blocks, thereby facilitating an efficient use of area;



► designing for waste minimisation by taking into account standard material sizes, specifying prefabricated products and using modular components (these measures can help reduce the amount of waste generated during the building phase and thereby reduce purchasing, handling and disposal costs); and

► designing for operational waste efficiency (i.e. those wastes generated once the facility is in use) and providing space/facilities to address the proper collection and disposal of food waste, beverage containers, paper, cardboard and other packaging materials, etc.

4.10.2 Design and Materials Efficiency

Building design and construction practices should minimise waste generation during construction, and facilitate the reuse/recycling of unavoidable waste.

Department of Education and TrainingSection 5 – Special Factors

5. SPECIAL FACTORS

5.1 Introduction

Special factors associated with the construction of a facility may lead to additional costs and affect the budget of an otherwise standard building project.

Investigations should demonstrate that alternatives have been evaluated, and all additions must be supported by estimates and quotations. Approval must also be obtained from the Department before incurring additional costs.

Only in circumstances where an extraordinary item arises (and for which no monetary allocation has been provided) will approval of additional project funds be considered.

Typical special factors affecting the cost of a building project include:

► existing site conditions;

► climatic conditions;

► existing conditions impacting on building design;

► access and servicing; and

► multi-storey or higher than normal buildings.

5.2 Process

The project budget may be increased at project initiation or during its development following a review of submissions and Departmental approval.

Each special factor needs to be quantified and reasons and/or reports provided to justify such budget allocations.

During the course of the documentation, the principal consultant must supply a detailed confirmation of the cost of each special factor specified in the original budget. Budget allocations will be modified and approved during the course of documentation, subject to Department review and approval.

5.3 Common Special Factors

It is not possible to identify all items that may be considered special factors, and only the most common are defined as follows.



5.3.1 Existing Site and Building Conditions

Due to the condition of the site, additional works may be required to an otherwise standard building project. Such works may be generated by factors associated with:

► rock

► soil

► flood-prone land

► slope of site (where the fall across the site is 1:20 or steeper)

► filled sites

► fill provision

► swampy ground

► bulk excavation

► site contamination.

The impact on the construction method and/or the additional works involved must be identified and the likely cost quantified and approved by the Department.

Additional works involving existing infrastructure may also arise from:

► the need to remove hazardous materials (see Section 5.3.4 below);

► decanting requirements;

► poor structural or maintenance condition of existing buildings and facilities; and

► excessive noise, vibration and fumes (aeroplanes, trains, heavy traffic, industrial processes ).

The corresponding additional works must be identified and the costs estimated, and submitted for approval to the Department.

5.3.2 Climatic Conditions

Special provision may be required for climatic factors. For example, snow entrances may be warranted in alpine regions, and proximity to the sea (generally within one kilometre) or location within industrial areas may require special coatings such as hot-dip galvanising.

However, high rainfall does not represent a design modification, and is normally covered in the Department’s locality allowance.

5.3.3 Maintenance Access and Servicing

Adverse site characteristics may incur:

► excessive service runs as a result of current service locations;



► the upgrade of existing external works and services as a result of additional “loads” imposed;

► buildings required to house engineering services (e.g. pump house, substation, gas meter enclosure);

► the bringing of service supplies to the site boundary;

► service and local government authority requirements (e.g. headworks and outfall charges); and

► temporary access.

The impact of the additional works must be identified and the likely cost quantified and approved by the Department.

5.3.4 Hazardous Materials

Hazardous materials include chemicals, cleaning agents, fuel, oils, asbestos, synthetic mineral fibres (SMFs) and PCBs.

All schools have been subject to an audit of asbestos and polychlorinated biphenyls (PCBs), and have received reports detailing the location of any of these within the school. (It should be noted that all PCBs have been removed from school buildings.) The audits, typically, also identify the presence of other hazardous materials.

Architects must ensure that tender documentation identifies the removal of all known hazardous materials within areas where upgrade is to occur.

Refer also to Section 11 – Workplace Health & Safety.

5.3.5 Multi-storey or Higher than Normal Buildings

Site topography or existing buildings may necessitate that new school facilities be multi-storeyed.

Because of higher roofs, extra footings, provision of lifts etc., a budget increase for proposed buildings or parts of buildings may be considered. The impact of the additional works must be identified and the likely cost quantified and approved by the Department.

As a general rule the acceptable cost increase due to two-storey structures is an additional 15% (i.e. 115%) of the rate for a new build $/m². This covers all structural factors in two-storey construction, including increased footing, pad, column sizes, load-bearing walls, suspended slab additional thickness, and band beams, etc. This also allows for an internal stair within the internal circulation area planned. However, a lift and all the necessary structure to support it is specifically excluded.

Disability access must also be provided in accordance with the Building Code of Australia and the Disability (Access to Premises – Buildings) Standards 2010. For example, this may necessitate the substitution of ramps for stairs where practicable. Other factors such as external ramps should also be included.



5.3.6 Specialist and Special Developmental Schools

Additional factors may apply to specialist and special developmental schools. Airconditioning is an entitlement in specialist and special developmental schools, and rates will need to be adjusted accordingly. Other special factors will need to be assessed on a case-by-case basis but may include:

► the necessity of smoke/fire detection systems to deactivate magnetic locks;

► glazing below one metre to exceed the Australian Standard and achieve greater impact resistance;

► automatic opening front door and security issues; and

► fencing types and security/containment issues.

5.4 Items Not Generally Considered ‘Special Factors’

The following items are not generally considered special factors and are accommodated within other components of the project budget.

Location Allowance

In general, projects constructed outside the metropolitan area bring with them increased costs.

Price Escalation and Rise and Fall during Documentation and Construction

The Department does not budget for escalation or rise and fall costs when determining its budget for a project.

Above Standard Facilities

When projects are documented over and above the Department’s current facilities standards, all additional costs are to be borne by the school. No additional funds will be provided.

5.5 Increased School Construction Rates

Special factors should only be considered for site-specific conditions as set out in the previous clauses.

Additional ecologically sustainable design (ESD) initiatives will only be considered on an individual project basis, and subject to approval.

School construction rates have been revised to include:

► allowance for all Building Code of Australia Part J requirements;

► physical barrier termite treatment in all projects;

► rainwater storage and toilet flushing systems;

► daylight sensing controls for classroom lighting;



► electrical floor boxes to open learning areas (average of two per general-purpose classroom equivalent);

► external access (one door per general-purpose classroom equivalent);

► low E glass to north and west facades;

► roof insulation at R3.5, wall insulation at R2.5;

► fittings and special equipment;

► cabling, communications and power;

► 80% of travel at an internal rate, and 20% at an external rate ($500/sqm); and

► locker areas and site stores as part internal, part external, at average rate of $900/sqm.

Department of Education and TrainingSection 6 - Substructure, Superstructure & Finishes

6. SUBSTRUCTURE, SUPERSTRUCTURE & FINISHES

6.1 Introduction

In choosing a design solution for new schools and refurbishment projects, the Department helps architects and school planning committees select from a variety of building systems consistent with good architectural and engineering practice, durability and value for money. The Department has developed a considerable body of experience from a range of projects that have been delivered and subsequently evaluated, as well as from the feedback supplied by end users – the schools themselves.

The purpose of this section is to provide school communities and consultants with the benefit of that experience so that demonstrated examples of best practice can be incorporated into new projects.

The following material is arranged according to the standard cost elements of a building project and generally provides details for minimum acceptable standards.

The materials and building practices listed are not exhaustive, and any materials not covered in this document should be considered in relation to those included. It is recommended, however, that specified fittings and equipment be sourced, where possible, from Australian suppliers in order to assure replacement parts and facilitate maintenance. These comments do not apply to modular relocatable buildings or unenclosed covered walkways.

All design, materials, workmanship, testing and commissioning shall comply with the latest revision of the Building Code of Australia and relevant Australian Standards.

6.2 Substructure

6.2.1 Site Conditions and Investigation

The type of structure best employed is dependent on site conditions. Prior to the commencement of design work, site investigations should be carried out, including:

► land surveys to determine slopes and above ground site features;

► watercourses, areas subject to inundation and overland flow paths; water table and levels;

► borehole and geotechnical investigations to determine, as best as possible, sub-surface conditions; and

► an examination of past construction records in the area, sourced from local authorities, schools, etc.

This will allow informed decisions to be made with respect to the stability or otherwise of founding material, the suitability of excavated material for engineered and/or bulk fill, estimates of any rock excavation, and the most appropriate substructure. It should be noted that rock excavation is both expensive and time consuming. Consideration should be given to floor and services levels in relation to possible rock.



All geotechnical investigations shall be conducted in accordance with AS 1289 to determine soil strength, shrinkage and bearing parameters. Foundation soil types shall be classified in accordance with AS 2870 and a relevant footing system designed to comply with building design and performance criteria in accordance with loading combinations specified in AS/NZS 1170 Parts 1, 2, 3 and AS 1170.4.

6.2.2 Preparation and Groundwork

Earthworks

Appropriate planning and management of this activity should take place all in accordance with AS 3798 and authority requirements.

Service Trenching

Trenching should be carried out and reinstated as soon as possible to avoid injury to individuals.

Appropriate service utility clearance, trench base, and reinstatement material and compaction should be completed to authority standards.

Stormwater – Site

A stormwater management plan should be created and maintained during the construction period. The use of sand bags or alternate earth drains are required to avoid sediment runoff and concentrated water flow into areas that would create property damage or injury.

6.2.3 Termite Management

Termite protection is required for all projects as termite attack is increasing in areas where they were not previously encountered. For this reason, School Construction Rates have been adjusted to provide for the cost of this treatment to all projects. (Refer to Section 5.5 in Special Factors)

AS 3660.1 “Termite management Part 1: New building work” is the relevant standard, and the requirements of this standard are to be applied.

Note that chemical soil barriers are subject to a loss of effectiveness over time. Different chemicals have different life spans, but no chemical currently on the market will last for the life of the building. It is therefore advisable to seriously consider the type of barrier system, as the reapplication of the chemical may be disruptive and/or costly. Chemical barriers created by means of reticulation pipework enable simple re-application of the chemical.

The Department publication Use of Termiticides in Schools applies mainly to maintenance activities for completed buildings, and particularly to the use of termiticide sprays.



6.3 Superstructure

6.3.1 Use of Appropriate Structural Solutions

Buildings should be designed to facilitate future school requirements as well as construction over the winter period.

The structural system should be as simple and robust as possible. Load-bearing vertical structure should be located in external wall-lines and in internal wall-lines that are unlikely to be relocated in the event of future building refurbishment.

Wherever possible, it is recommended that a stiffened concrete raft solution be utilised for the floor, appropriately designed for the site conditions. Such a solution can reduce long-term superstructure damage from seasonal ground movements, and is very low maintenance (it incurs good life-cycle costs).

For sites on slopes, or for sites with difficult founding conditions, it may be appropriate to raise the floor structure.

Current local market conditions may also influence the final choice of structure, as costs of alternative structural systems can and do vary with time, and can be influenced by site location.

A certificate of structural adequacy for all footing systems and structural members of the building shall be provided with the final detailed design drawings and documentation.

6.3.2 Concrete

All concrete structures shall be designed in accordance with AS 3600.

Precast, tilt-up and concrete structural elements shall be designed in accordance with the relevant codes AS3850.1 and 2, AS 3610, etc.

All steel reinforcement of concrete shall be in accordance with AS/NZS 4671 and designated grades N, L, R and RF. Minimum reinforcement cover shall be in accordance with AS 3600.

6.3.3 Masonry

All masonry structural elements/components and construction shall comply with AS 3700 and AS/NZS 2699.1 and 2.

Stack bonded masonry (brickwork or blockwork) is not to be used under any circumstances.



6.3.4 Steel

All exposed steel columns should be hot-dipped galvanised in accordance with the exposure category in AS 3600. If paint is to be applied for decorative purposes, the appropriate primers and treatment should be used.

Handrails should be hot-dipped galvanised in accordance with the exposure category in AS 3600 (450 g/m² for normal sites, 600 g/m² for corrosion sites) and not painted, as the paint will quickly wear off.

6.3.5 Timber

All timber structural members shall be designed in accordance with AS 1720 and AS1684.

6.4 Roof

Simple roof forms are required, with roof guttering outside the line of external walls (i.e. no box gutters). Attention should also be given to means of avoiding gutter blockage by leaves and debris.

During selection, consideration must be given to the continued availability of roofing materials.

6.4.1 Designs to Conform to AS/NZS 3500.3

AS/NZS 3500.3 Plumbing and Drainage Part 3: Stormwater Drainage is referenced by the Building Code of Australia and thus roofing, gutters and downpipes are required to be designed to meet the requirements of this standard. The standard enables calculations to be made regarding quantities of rainwater collected by roofs as well as the sizing of gutters and downpipes to meet local rainfall conditions within appropriate “design return” periods.

The design must incorporate a provision enabling any water overflow to escape outside the building. Requirements for overflows are provided by AS/NZS 3500.3. Box gutters must not be used. Where it is unavoidable, the use of box gutters must be approved by the Victorian School Building Authority, DET.

6.4.2 Materials and Safe Access

Roofing material is to be surface/pierced fixed steel sheeting. The use of clip-fixed decking should be kept to a minimum to minimise roofing costs.

All roofing must be of continuous sheets from ridge to eaves wherever possible, with a minimum slope of at least three degrees.

The sheeting shall be pre-painted steel on zincalume substrate. The Department will consider natural finish steel sheeting where it matches existing materials or must conform with local



government requirements or where the principal consultant provides acceptable evidence to support the material choice.

Other materials may be used in special circumstances. Each application will be assessed on its merits. Consideration should be given to the effects of galvanic corrosion when selecting roofing materials.

To reduce damage caused by intruders walking on the roof:

► use the thickest available roof sheeting (ductile corrugated sheeting is available in 0.6 and 0.8mm whereas most standard profiles are only available in 0.42 or 0.48mm thickness);

► preferably use stronger profiles of metal roofing rather than corrugated roofing;

► decrease the batten spacing to a maximum of 1000mm for metal deck roofing and 600mm for corrugated roofing; and

► increase the roof pitch.

Selection of the appropriate roof profile is a cost/benefit exercise. Stronger profiles are only available in narrower sheets. See table below for comparison of typical sections available.

Profile Thickness Maximum Single Span Minimum Pitch

Standard Corrugated 0.48 (thickest available) 800 5°

Ductile Corrugated 0.6 1600 5°

Rib and Pan 0.48 (thickest available) 1600 2°

Ductile Corrugated 0.8 (thickest available) 1800 5°

Ribbed 0.48 (thickest available) 2000 3°

Slopes and spans of roofing should preferably exceed the manufacturer’s minimum requirements to avoid pooling of water and dinting of roof profiles by roof traffic. Experience shows that roofing will deflect under foot traffic loads at recommended maximum spans.

Roof sheeting may also be damaged in transit or during erection, creating defects in the designed profile shape. Damaged sheets shall be rejected.

Safe Access to Roofs

Over and above requirements of the Building Code of Australia, Victoria’s Occupational Health and Safety legislation places an obligation on owners and designers of buildings to ensure that persons employed (including contractors) on their premises are provided with safe workplace conditions. The relevant regulations in regard to roof access are the Occupational Health and Safety Regulations 2007, and in particular Part 3.3 – Prevention of Falls.



While each person accessing the roof must be covered by occupational health and safety procedures implemented by the school, it may be advantageous to design suitable items to facilitate access to the roof for maintenance purposes. This is particularly so if items of equipment requiring regular maintenance are mounted on the roof. Note that a contractor engaged to undertake work on the roof is considered to be a school employee for the purposes of the Act.

Simple devices such as ladder-fixing brackets located at suitable access points and roof-mounted anchor points for safety lines will facilitate safe access to roofs.

Refer to Section 11 for further information on workplace health and safety.

6.4.3 Gutters and Downpipes

General

Site and roof drainage systems should provide inbuilt redundancy in both number (more than one outlet) and type (down-pipes and ability of the gutter to overflow without nuisance; grated stormwater (SW) pits and independent overland flow around the buildings). The back-up should (ideally) be open ended (i.e. of virtually unlimited capacity if not well in excess of the anticipated design flows – e.g. lower fronted eaves gutters) and not maintenance dependent.

The design should include complete levels for the buildings, civil and landscape works and ground levels around the buildings. These should include levels for SW inlets and outfalls, grades around (and away from) buildings, swales and surface drains. Over-sizing of infrastructure should be encouraged, beyond meeting current design standards.

Roofing, gutters and downpipes should be of electrolytically similar materials to avoid corrosion. The sheet thickness of gutters and downpipes (as well as their fixings) must be able to withstand mechanical and other damage.

Low Level Gutters in Trafficable Areas

Guttering below 2400mm above ground level in trafficable areas will require fixing of a standard in excess of normal manufacturer’s requirements.

Mesh Covers to Gutters

Mesh covers are sometimes fitted to gutters to prevent blockage by leaves. Plastic mesh is unsatisfactory as the weight of debris will collapse the gutter. Mesh should be made of metal compatible with the roof and gutter, and it must be secured in such a way as to prevent leaves working beneath it (preferably, mesh should be inserted beneath the roofing). If mesh covered gutters are blocked, they will be difficult to clean.

In heavy rain, mesh covering can deflect water across the gutter to discharge onto the ground or path below. This needs to be considered in the choice of design, particularly over building entries. Some mesh guards are dished slightly.



Location of Downpipes

Consideration should be given to locating downpipes, wherever possible, in protected areas away from heavy student traffic to prevent damage to downpipes.

Downpipes must not be concealed in wall cavities where any leak will result in structural and aesthetic damage.

Protection of Downpipes

Sheet metal downpipes at schools have been consistently deformed by impact. Downpipes are required to be of a more robust quality from ground level to a minimum height of at least 1800mm. This will require the use of materials such as sewer quality PVC pipe or, in more extreme cases, galvanised steel water pipe. Alternatively, sleeves to a height of at least 1800mm should be used to protect standard downpipes.

Give consideration to locating downpipes over grated pits and stopping downpipes short of the ground level to prevent balls, etc., entering the stormwater system.

Damage Prevention

Damage generally occurs to guttering during after hours when vandals either swing from it or use it to access the roof. Stronger fixing will not preclude damage, and guttering is not available in sufficiently heavy gauge to resist damage. It is recommended that the height of guttering from paving or garden areas be a minimum of 2400mm. Consideration should also be given during the planning stage to design solutions which pre-empt or minimise damage to roofing and guttering at low points in the building structure.

6.4.4 Roof Insulation and Ventilation

Insulation

Provide roof/ceiling insulation according to the table below (postcode areas for NatHERS zones are supplied in Appendix 3):

NatHERS Zone 27i.e. Mildura

NatHERS Zone 20i.e. Benalla

NatHERS Zones 21 & 22 i.e. Melbourne

RecommendedR value

R4(if heating & cooling)


R3(if heating only)


R2.5(if heating only)

R4(if heating. & cooling)


Note: An increase in School Construction Rates now provides funding to R3.5 for roof/ceiling construction.

The insulation of walls and roofing must be addressed in the Schematic Design report.



Roof Ventilation

Consider roof ventilation above the level of ceiling insulation for summer cooling.

Roof Colour

Roofs are to be light in colour if appropriate for the surrounding environment. This will help reduce summer overheating. The colour of the roof must be addressed in the Schematic Design report.

6.4.5 Skylights and Clerestory Windows

Windows alone are often unable to provide efficient daylighting for deep floor spaces where the external wall is too far for daylight to reach, even with the use of light shelves and other devices. Some internal spaces may not have external walls. In such places the use of clerestory windows or skylights to introduce natural light (and ventilation if required) can be advantageous. However, all forms of daylighting require careful design to introduce light without glare and heat.

South-facing clerestory windows are usually preferable to skylights. North-facing clerestory windows are not considered advisable because of the penetration of direct sun into learning spaces. If there is a compelling reason for such a design, such windows must be protected by shading devices which employ suitable sun-penetrations software.

Many different forms of skylight have become available, including devices to control and select the light admitted. Most are now rated under the skylight module of the Window Energy Rating Scheme, known as WERS for Skylights. The scheme takes account of key differences between the energy performance of windows and skylights and the differing responses of buildings to these fenestration products.

Where skylights are installed to facilitate the entry of daylight, their area should be approximately 8% of the floor area served, provided they are externally shaded. A rule of thumb regarding distribution of skylights is that their centres should be 1.5 times the ceiling height. The requirements can be calculated with appropriate software. US-based advice, Skylighting Design Guidelines, is available at: http://energydesignresources.com/resources/publications/design-guidelines/design-guidelines-skylighting-guidelines.aspx.

It is beneficial to the spread of light and reduction of unwanted heat transfer if skylights are sealed with an acrylic/prismatic diffuser. Double-glazed domes and double glazed ceiling level diffusers are available. Shade all skylights which illuminate occupied areas. Skylights in heated areas shall be of the non-ventilated type. All skylights should be fitted with safety grilles or other means of fall-prevention for persons on the roof. Some types of skylight are made of impact resistant material and will not require grilles.

For unheated areas such as toilets, changing rooms, corridors and vestibules, clear sections of roofing may be useful. These should be designed to provide a passive solar benefit. Lighting controls should also be provided so that lights can be switched off.

Tubular skylights and angular selective skylights are now available which restrict the light and heat input when the sun is directly above and increase light input when the sun is lower in the sky. This is


http://energydesignresources.com/resources/publications/design-guidelines/design-guidelines-skylighting-guidelines.aspx

http://energydesignresources.com/resources/publications/design-guidelines/design-guidelines-skylighting-guidelines.aspx


done by means of light-intercepting devices inside the dome or laser cuts on the dome surface. These units can also include dimming controls, double-glazed ceiling diffusers, etc.

6.5 External Walls and Floors

6.5.1 Cladding Materials

External wall cladding should be chosen from a select range of environmentally friendly materials designed to provide:

► long term durability;

► low maintenance costs (e.g. cleaning);

► stain and graffiti resistance;

► an appropriate level of insulation for acoustic and thermal purposes;

► aesthetic appeal; and

► value for money.

Selection of appropriate surface finishes must proceed with a knowledge of the activities to be conducted in the area.

Only surface finishes which maintain their original character and do not rely on regular maintenance and cleaning should be selected. External cladding should be employed in such a way as to ensure minimum cleaning; for example, corrugated iron must not be used horizontally.

Walls must be capable of being easily cleaned and repaired if damaged. Concrete block and other materials prone to dirt and scuffing, or difficult to clean or remove graffiti from, should be avoided.

External walls should be of masonry, in general, and to a minimum height above ground level of at least 2100mm (door head height). Masonry could be continued to the bottom of the eaves, however lightweight cladding is an acceptable alternative.

Other alternatives such as full height lightweight cladding may be considered in certain circumstances, for instance, low traffic areas and areas of low visual impact.

Externally, pre-coated surfaces should be used. External painting should be minimised and restricted to secure areas.

Any solution recommended by the principal consultant must be cost effective (but not to the extent that future maintenance is compromised) and agreed to by the Department’s Project Review and Evaluation Panel (PREP) before implementation.

6.5.2 Wall Insulation

External wall insulation should be provided as described in the table below. Where internal walls face onto breezeways that are open at both ends, they should be treated as external walls. (Postcode areas of all NatHERS zones are supplied in Appendix 3.)

Note: An increase in School Construction Rates now provides funding to R2.5 for wall construction.

6.5.3 Wall Colour and Texture

Consideration should be given to the light colouring of external walls to reflect heat, especially along the west facade. Avoid matt colours and heavily textured surfaces.

Only surface textures which maintain their original character and do not rely on regular maintenance and cleaning should be selected.

6.5.4 Flooring

Wherever possible, it is recommended that a stiffened concrete raft solution be utilised for the floor, appropriately designed for the site conditions. Such a solution can reduce long-term superstructure damage from seasonal ground movements, and is very low maintenance (it incurs good life-cycle costs).

For sites on slopes, or for sites with difficult founding conditions, it may be appropriate to raise the floor structure.

6.5.5 Floor Insulation

Floors should be insulated. Although concrete floors have an inherent insulation value of about R1.5, the 600mm to 1000mm perimeter edge should be provided with insulation. Timber floors should be insulated to an equivalent R1.5 level.

Insulation for timber floors can be provided in the form of CFC-free polystyrene boards or foil batts suitable for exterior use and fixed between joists. Provide an air space between the floor boards and the insulation. Sub-floor ventilation should also be minimised but still comply with the Building Code of Australia in order to further minimise heat loss.

Timber floors to physical education spaces should not be insulated, but timber floors to multi-purpose spaces in primary schools should be insulated.

The insulation of timber floors needs to be addressed in the Schematic Design report.



6.6 External Windows

6.6.1 Glass

Glass in windows and doors shall comply with the Building Code of Australia and AS 1288: Glass in Buildings – Selection and Installation.

Exterior glass in windows and doors must also satisfy Building Code of Australia Part J 2 for energy efficiency measures.

Glazed doors, and glass panels that could be mistaken for openings, should have markings that accord with the Building Code of Australia.

6.6.2 Standard Windows

The selection of windows should focus on standard designs and availability, standard construction techniques, low maintenance and maximum user safety.

Glazing must conform to relevant regulations and Australian Standard. Minimum glass thickness is dependent on location as specified in AS 1288.

Consideration must be given to cleaning costs, i.e. high-level glass should be avoided or provided with means of safe access for cleaning.

Windows must be properly weatherproofed and should be provided with protection from climatic influences by means of eaves or canopies.

Windows should be aluminium-framed and of commercial quality.

Care must be taken to ensure that the structural stability of the window meets appropriate wind loading and impact resistance levels.

Once a window type is chosen, that type shall be carried throughout the design of the entire school.

6.6.3 Higher Quality Windows

Unprotected windows in high-traffic, playground and vandal-prone areas must possess a level of impact resistance. This requires the specification of Grade A safety glass in accordance with AS 1288-2066. Glazing within 1000mm of floor or ground level is covered by AS 1288; however, it may also be necessary to specify Grade A safety glass for glazing between 1000mm and 1800mm where the risk of breakage is considered to be high.

Enhanced solutions (including thickness, double glazing and tinting) may be appropriate to reduce noise, sun glare, and heat gain and loss.

The School Construction Rates now allow for the use of Low E glass to north and west facades.

The principal consultant must qualify the situation when higher window quality is required.



6.6.4 Window Finish

Powder-coated window frames are to be light coloured if they are to be positioned in direct sunlight. Manufacturers of powder coatings advise that light colours are more durable than dark colours as they absorb less solar radiation. Bright colours are even more prone to fading than dark colours for the same reason.

6.6.5 Window Configuration

Sashes should be either sliding or double hung.

Full-height glazing is to be avoided wherever possible to minimise safety and maintenance hazards, particularly in areas where queuing or heavy traffic occurs. Ensure that window sills are located at least 50mm above floor level, ideally 1200mm for thermal efficiency. Low windows are of no passive solar heating or daylighting benefit.

While awning windows are not permitted at ground-level traffic areas due to the possible hazard to passers by, highlight awning windows are acceptable where security can be maintained.

Operable louvres or awning windows to clerestories may be used to promote good cross ventilation, with some inbuilt weather protection. High-level windows should be operated by a remote winder that secures the windows when shut.

The use of frameless sliding glass or louvre windows is not permitted at normal levels due to possible injury arising from impact.

6.6.6 Sun Control and Ventilation

Direct sunlight is not to penetrate windows during summer and shoulder seasons.

Where east- and west-facing windows are necessarily incorporated, the use of high-performance glazing shall be considered to control sun penetration.

Design consideration shall be given to providing adequate (preferably cross flow) ventilation, and should, wherever possible, provide natural lighting from two opposite sides of an activity area.

Issues Encountered – What to Do; What Not to Do

Excessive entry of natural light leads to heat and glare issues. Unsatisfactory designs feature:

► no external sun shading, often on the north side;

► poor design of sun shading;

► non-durable devices (e.g. timber pergolas); and

► ineffective screens made of expanded metal.



Where too much glare or direct sun penetration occurs, the response is to blank out the windows with blinds or other means and switch the lights on, resulting in a frustration of the intended objective.

Examples of successful control include:

► sun-shading devices of many different types provided to windows and skylights;

► inclusion of blinds of an appropriate type, particularly for media presentations, also see-through blinds to utilise views to the north (these may be supplemented by external shading);

► use of pop-up roofs with appropriately oriented or protected clerestory windows to provide light and ventilation;

► adjacent verandas and covered walkways used as shading for windows; and

► orientation of building/window openings to select desirable light input.

In relation to older LTC (light timber construction) school buildings, these suffer from a lack of natural light in their double-loaded central corridors. The recessed roof area also presents drainage difficulties. Some solutions devised to overcome these issues include:

► raising the corridor roof to the level of adjacent roofs, and providing natural light through skylights; and

► raising the roof to the level of adjacent roofs, with natural light provided by angling the roof and installing clerestory windows along one side.

6.6.7 Sealing of Windows

Provide windows with weather seals.

6.6.8 Louvre Windows

The use of frameless louvre windows is not permitted at normal levels due to possible injury arising from impact.

High-level windows should be operated by a remote winder that secures the windows when shut.

6.6.9 Insect Screens

The provision of insect screens is acceptable in food preparation areas only.

Insect screens may be considered for windows or openings which provide night purging as protection from mosquitoes and other insects.

Any insect screens provided must be of commercial quality and fitted with aluminium or stainless steel mesh.



6.6.10 Window Hardware

Hardware for aluminium windows must be of commercial standard. Domestic quality is unacceptable.

All double-hung windows must have spring balances of an appropriate design. Window selection should ensure that the balance mechanism is not so stiff that the window is difficult to open but stiff enough to prevent the sash moving under its own weight.

Window operating devices should be operable by all potential users, including people with disabilities.

6.6.11 Sizing of Windows

Windows should be oriented so that the majority face north and south, and the amount of east- and west-facing glass is minimised (this must be addressed in the Masterplan report).

Window sizing should subscribe to the minimum requirements of the relevant Australian Standard. In their sizing, the aim is to achieve a balance of daylight, view, heat gain and heat loss. Bearing this in mind:

North Windows: Size north facing windows at 20% of the floor area they serve so that they benefit daylighting and passive solar heating.

South Windows: Size south facing windows to minimise heat loss in winter while ensuring that they provide adequate daylight to rooms all year round. A figure of 10% of the floor area is suggested as a useful starting point for sizing.

East and West Windows:

Minimise east and west facing glass, and make the maximum size of glass 5% percent of floor area they serve. If windows are larger than this, consider movable external blinds to totally cover the window, or fixed vertical fins or egg crate shades.

Note: In accordance with “F4.2” of the Building Code of Australia, the aggregate light transmitting area should not be less than 10% of a room’s floor area.

6.6.12 Shading of Windows

Shade north facing windows with appropriate eaves or a fixed shading device comprising a vertical shading angle of at least 56 degrees measured from the window sill. Extend the shading device one metre past each end of the window. On east- and west-facing windows, vertical shading is effective. (The shading of windows must be addressed in the Schematic Design report.)



6.7 Doors and Hatches

6.7.1 External Doors

External doors should:

► in general, be of standard dimensions (of no more than 2100mm height) and comply with the Building Code of Australia;

► not be too large, as large and heavy doors are difficult for small children to open (the current trend for full-height doors creates a problem in this respect. If a large door is fitted with a door closer of sufficient strength, this adds to the problem. The operating force for doors should accord with the Building Code of Australia);

► be at least half glazed with safety glass for two-way vision in trafficable areas (the size of glass panels must accord with AS 1428.1);

► be able to cope with heavy and constant usage;

► be sufficiently robust to provide appropriate security to the building;

► be properly weatherproofed and protected from climatic influences;

► be either solid core timber with three hinges per doorORbe aluminium with appropriately heavy sections and fixing to prevent long term sagging, with pivot hinges;

► have an additional hinge fitted to the top of the door where door-closers are fitted to external doors or large internal doors;

► have any door fixings to lightweight metal provided with backing plates for support;

► be provided with restrainers, door stops, etc. to prevent impact to adjoining surfaces;

► be provided with metal framing;

► if aluminium, be constructed from a commercial-grade section and have a solid bottom panel;

► have lever-style handles in accordance with the Building Code of Australia (handles and mechanism should be sufficiently robust to withstand vandalism, abuse and the effects of frequent use);

► provide a level of access appropriate to the purpose of the space for which they are used;

► be fire rated or smoke sealed as required by the Building Code of Australia;



► be fitted with weather seals to the bottoms and edges, and to the jambs meeting stiles of double doors;

► provide air locks to main entrances accessing heated areas (air lock sizes should accord with the Building Code of Australia;

► be provided with mat wells at all entrances (the mats should be recessed or have tapered edges as shown in the Building Code of Australia);

► include fittings such as door handles in primary schools that are appropriate for small children; and

► if a required exit, be a single-action opening door, openable from the inside as required by the Building Code of Australia.

6.7.2 Hinge Stress

Failure of external doors is largely attributable to hinge stress. The over extension of doors by wind or students will damage components such as frames and hinges. Damage also occurs when doors are pushed against the action of door closers. Such damage can be minimised by:

► locating doors adjacent to walls to provide a definite door stop;

► locating doors in sheltered locations;

► providing all external doors with door stops or steel handrails on the hinge side;

► constructing aluminium doors with pivot type hinges complete with floor springs and concealed head closers; and

► minimising the number of external doors (e.g. no external doors to general purpose classrooms).

Door stops should not be located close to the hinge. The action of the door impacting on the stop will break the bottom hinge. If a floor-mounted door stop creates a trip hazard when fixed in the normal location beneath the handle, a door stay can be used, fixed to the head of the door.

6.7.3 Internal Doors

Internal doors should have the same qualities as external doors except that there is no requirement for weatherproofing.

Internal doors need not necessarily be metal framed, except where frequent impact is likely, and may also have loose-pin hinges.

Zoning

Internal doors should be provided to separate heated from non-heated spaces on the same level. Doors are also required to separate one level from another, thereby preventing the rise of heated air to an upper level. Consider door seals to improve the separation, especially on doors that open onto stairwells.



6.7.4 Smoke and Fire Doors

Smoke and fire doors shall be provided as required by the Building Code of Australia.

Magnetic hold-open devices should be provided for these doors.

Equipment should comply with the various parts of AS 1670 fire detection, warning, control and intercom systems.

Refer also Section 7.9 – Fire Protection and Section 7.9.3.

6.7.5 Selection and Detailing of Operable Walls

Operable walls can be problematic and require care in selection and the design of their installation. Poor detailing and construction can result in inadequate acoustic separation and hinge failure.

Operable walls need to be operated and secured in position without a requirement for physical strength.

The quality of operable walls varies considerably. These wall-doors are expensive, but selecting a lower-cost door can make them a liability instead of an advantage.

6.7.6 Proprietary Aluminium Stud Partition Type Door Frames

Proprietary systems of aluminium framing for doors and glazed partitions designed to suit metal stud wall framing have door frames which do not include corner reinforcement stakes. This means that the force of a door closer operating on the head of the door frame breaks the joint between head and jamb and allows the head to twist away from the wall face. This method of door framing should be avoided, particularly where door closers are likely to be held open.

6.7.7 Door Hardware

Selection of Hardware

All hardware should be commercial quality and able to withstand heavy usage.

Back-sets need to be selected to suit the door. Many aluminium framed doors have locks with too short a back-set, resulting in fingers being jammed against the door frame when the door is opened.

Master Keying

All locks should be part of the school master-key system.



Hinges and Handle Requirements

Refer also Section 6.7.2 – Hinge Stress

Large D-shaped door-pulls have been found to come loose and are a maintenance problem.

Smoke and Fire Door Hardware

Magnetic hold-open devices connected to the smoke detector/fire alarm system shall be provided to doors between smoke and fire compartments. Equipment installation and system design should comply with the requirements of AS 1670 and associated Australian Standards.

Refer also Section 6.7.4, Section 7.9 – Fire Protection and Section 7.9.3

6.8 Ceilings

6.8.1 Ceiling Materials

As appropriate in most areas, the minimum standard finish is 13mm plasterboard fixed to metal or timber framing, or mineral fibre acoustic tiles with a minimum noise reduction coefficient (NRC) rating of 0.7.

Ceiling finishes should be consistent with the acoustic standards described in Section 6.10.3 and Section 6.11, and should ensure adequate light reflection.

In some areas flush plasterboard ceilings will be acoustically adequate; however, acoustically rated ceilings will be needed to meet recommended performance in many spaces. (Refer to Section 6.11.7 for specific requirements on acoustic performance).

Ceiling finishes should be selected to provide an appropriate acoustic value for a room according to its proposed usage.

It is recommended that acoustic tile ceilings be used in all general-purpose classrooms (GPCs). Note that acoustic tile ceilings are not necessarily more expensive than plasterboard, depending on the tile selected.

6.8.2 Spaces above Ceilings

Sufficient space above the ceiling should be allowed for services, and access must be made available for future installations.


Post-occupancy evaluations have previously noted an insufficient number of hinges used on doors, resulting in doors dropping and jamming. At least three heavy-duty stainless steel hinges are required.

59


Provision should be made for ceiling baffles to minimise sound transmission between rooms.

6.8.3 Ceiling Heights

Area Springing Height (m)

General-Purpose Classroom 2.4 (min) – 2.7 (across room average)*

Multi-Purpose Room (150m²) 4.0

Physical Education Space – Primary School (298m²) 4.0**

Physical Education Space/Gymnasium – Primary and Secondary Schools (688m²)

6.0

* General purpose classrooms should have a minimum average ceiling height of 2.7 metres to allow for the inclusion of ceiling fans and the penetration of natural light. The minimum height of ceiling fans, as measured to the underside of fan blades, shall be 2.4 metres from finished floor level.

** If the physical education facility is to be extended in the future, the added cost of providing a 6-metre rather than a 4-metre high roof shall be funded from sources other than Department (including extra foundation and structure costs). For design standards relating to ceiling heights for Competition Grade Facilities, see Appendix 4.

6.8.4 Clearance Heights under Stairs and Bulkheads

Ensure that at least 2100mm clearance is provided in all accessible areas, including beneath stairs and bulkheads.

6.8.5 Access to Lights

When designing ceilings, of access to light fittings for changing globes/tubes must be considered. This is a matter of practical maintenance for the school, but it should be noted that safe access for maintenance is also a requirement of occupational health and safety (OH&S) legislation.

Light fittings are to be mounted at levels below 2700mm above floor level. Where this is not possible, specific means of safe access to change globes must be provided, e.g. step ladders with a platform at the required working level.

6.9 Internal Walls

The type and suitability of internal wall framing is dependent on the height and materials to be fitted to the walls. Additional framing/noggings will be required at lining material junctions and for joinery as well as in some high traffic areas. Metal or timber framing is acceptable.



6.9.1 Room Dividers

Internal screens can enhance the flexible use of spaces in a school and enable a range of teaching and learning strategies to be employed.

Moveable internal screens can serve a variety of purposes and should be capable of quick and safe removal or relocation to facilitate alternative area use. They may serve display and space dividing purposes, and should generally offer appropriate acoustic separation when in place.

Where such screens are to be frequently utilised, they should be of a type that minimises the impact of any reduction in natural or borrowed light except where light exclusion or reduction is the objective.

Fixed screens should also be carefully selected to provide space separation without compromising light quality, and should facilitate supervision of the separated space where required.

6.9.2 Internal Glazing

Where internal glazing is to be used, similar criteria to external glazing should be employed.

AS 1288–2006 should be followed, particularly in relation to references to the use of glass in schools.

Internal glazing should only be installed in a vertical plane. This avoids costly premiums for the cleaning of inclined glass.

6.9.3 Operable Walls

Where operable walls are to be used, particularly between classrooms, consideration must be given to the following issues:

► acoustic qualities – often found unsatisfactory, yet must comply with the requirements of Section 6.11.5;

► weight and size – operable walls can be difficult to manipulate due to their dimensions; and

► wear and tear – deterioration in performance and operability arising from use and damage to seals, etc.

Other means of connecting spaces should be considered, but whatever means is utilised, acoustic transmission between adjacent spaces requires careful consideration.

For a standard new primary school of 451+ children, the maximum number of operable walls provided between classrooms is to be four, offering flexibility to provide eight general purpose classrooms.



6.9.4 Colour

Light colours should be applied to internal walls to maximise daylight benefit. The colour of internal walls must be addressed in the Schematic Design report.

6.9.5 Thermal Mass

Concrete slabs and masonry walls are effective in keeping down summer temperatures. Internal masonry brick and concrete block walls should be promoted to reduce overheating in schools located in NatHERS Zone 27 (e.g. Mildura – refer to Appendix 3 – Postcode Areas within NatHERS Zones). The incorporation of thermal mass (concrete slabs and masonry walls) must be addressed in the Schematic Design report.

6.10 Wall and Floor Finishes

Standards of finish must be maintained at levels adequate to cope with normal school usage but don’t require constant maintenance or repair. “Domestic” standard finishes, for example, in relation to plasterboard walls, carpets and splashbacks are not acceptable.

Finishes, materials and assemblies must possess fire-hazard properties compliant with the Building Code of Australia.

6.10.1 Wall Finishes

Selection of appropriate surface finishes must proceed with the knowledge of the activities, processes, materials and equipment relevant to individual spaces. Wall finishes must be of a standard type, easily cleaned and repaired if damaged.

Finishes must be assessed to ensure they do not create problems related to toxicity and become an occupational health and safety hazard.

Selected materials must also possess suitable wear and tear characteristics, including a high degree of impact resistance. In certain instances, they must be able to cope with uses unintended in the design (i.e. compressed sheeting to dado height in corridors and some classrooms, rather than plasterboard). The materials must be stain and graffiti resistant, and have low maintenance characteristics. Consideration should also be given to the low Spread-of-Flame Index and Smoke-Developed Index as well as acoustic properties in accordance with the Building Code of Australia.

Minimum provision is outlined in the following table:



Area Suggested Wall MaterialsHigh traffic areas/high use areas (e.g. corridors, classrooms)

13mm MDF or Villaboard to 1200mm high 13mm plasterboard above

Low traffic/low use areas 13mm plasterboard

Student toilet and shower/change areas Masonry to ceiling height Villaboard on timber framing

Naturally some exceptions exist, such as finishes to gymnasium walls. Exceptions, however, must be justified to the satisfaction of the Department’s Project Review and Evaluation Panel (PREP).

For higher noise-generating areas such as music, drama and technology spaces, consideration must be given to sound attenuation between areas.

Splashbacks are generally a minimum 300mm high and shall be tiles, stainless steel or a material to match the bench tops. Where splashbacks are of a material to match bench tops, they should be coved. Joints between bench and splashback (if any) and joints between splashback and walls should be sealed using a silicon sealant employed in accordance with manufacturer’s requirements. Fillets between adjacent surfaces are not satisfactory as they do not provide scope for elastic movement.

All grouting in toilets should be sealed.

6.10.2 Floor Finishes

Floors, as with other finishes in a school, are subject to very high levels of wear and tear and sometimes to instances of inappropriate use.

In general, floor finishes should provide high durability, be of a standard commercial grade/type enabling areas to be repaired or replaced economically, and must meet the Building Code of Australia requirements for safety, including its Spread-of-Flame and Smoke-Developed Indices.

The following additional factors should be considered:

► slippage – where water, oil, grease, sawdust, steps/stairs, etc. may occur (refer to AS/NZS 4586 Slip resistance classification of new pedestrian surface materials; SAA HB 197 An introductory guide to the slip resistance of pedestrian surface materials; and Natspec Technote DES001);

► sound – acoustic compatibility with background and activity noise levels; and

► comfort – thermal and tactile comfort in relation to the usage of the room.

There are an enormous number of proprietary-type floor finishes available to suit both wet and dry activities in schools.

This section of the document confines itself to those standard finishes which are commonly used in school situations.



The following sections provide a base standard for the provision of floor coverings to a majority of the floor area in a school. The use of other proprietary-type floor finishes may be acceptable provided cost and performance criteria equivalent to the following examples can be met. Ongoing maintenance costs are another important consideration.

The minimum standard for flooring in areas of a school are summarised in the following table:

Area Suggested Type of Material (Minimum Standard)

Carpet Vinyl/Linoleum Timber Epoxy FinishesGPC-SC GPC-PS Art 2D-SC/PS Art 3D Graphics Music - SC/PS Drama Info Tech Home Eco Fabrics Science Technology (Design) Library Phys Ed* (Cushioned) Multi Purpose Seminar Lecture Staff Admin (Wet Areas)Staff Work Canteen Change Shower First Aid Student Centre Toilet Circulation

* For design standards relating to flooring for Competition Grade Facilities, see Appendix 4.

Carpet

For schools, use carpets which are graded “Contract Extra Heavy Duty” by the Australian Carpet Classification Scheme (ACCS). ACCS licensees give a warranty with their carpets; this warranty is subject to proper installation and maintenance (AS 2454 Textile Floor Coverings – Terminology and AS/NZS 2455.1 and AS/NZS 2455.2 Textile Floor Coverings – Installation Practice will apply).

The ACCS licensee’s instructions for underlay should be followed (AS 4288 will apply).



The selection of carpet should take into account the properties of the underlying base or flooring. The substrata must comply with manufacturers’ and Australian Standards requirements (see above).

Carpets should not be installed in areas subject to wetting.

Spread-of-Flame and Smoke-Developed Indices are to be used as required by the Building Code of Australia.

Some carpets are “flocked” or “melded” products. The ACCS still applies.

Vinyl/Linoleum

All linoleum and vinyl flooring must be a genuine low maintenance product, with a clear upper surface treatment incorporated during manufacture and guaranteed for at least five years. The flooring material must be in sheet form and fully heat welded on installation (AS 1884 “Floor coverings – Resilient sheet and tiles – Laying and maintenance practices” will apply).

The material shall be at least 2mm thick. For homogeneous products, the nominated colours and patterns shall permeate this thickness. For heterogeneous products, the nominated colours and patterns shall permeate at least 0.7mm of this thickness.

The suppliers’ instructions for underlay should be followed (AS 4288–2003 “Soft underlays for textile floor coverings” will apply).

Vinyl flooring materials must be stain resistant. Importantly, they must be able to be “wet and dry” cleaned (in turn they must be waterproof and weldable).

Multi-purpose/physical education facilities can be provided with alternative finishes such as cushioned vinyl.


Recent post-occupancy evaluations have found a number of carpeted floors subject to lifting, possibly due to dampness in the floor beneath. Substrata must be tested before carpet is laid. AS 2455 specifies requirements for substrata.

65


Timber

Timber floors for internal activities are restricted to gymnasium areas in secondary colleges (and, in certain circumstances, drama facilities). Gymnasia can be provided with a sprung timber floor only where competition sport is to be played under a joint-use agreement and the capital and maintenance cost of the floor is shared. The timber floor may be provided over either concrete slab or timber framed on concrete footings.

Epoxy Floor Finishes

These finishes are generally restricted to use in toilets, shower/change facilities or certain specialist areas.

Epoxy finishes should be applied by trowel on application, not painted, and be a minimum of 6mm thick.

Where tiles are employed in wet areas, all grouting must be sealed and impervious to moisture. Regular resealing must be undertaken to avert potential health hazards.

6.10.3 Ceiling Finishes

Ceiling finishes should be selected to provide an appropriate acoustic value for a room according to its proposed usage and to ensure adequate light reflection.

Sufficient space should be allowed for services, and access must be made available for future installations.

Provision should be made for ceiling baffles to minimise sound transmission between rooms.

As appropriate in most areas, the minimum standard finish is 10mm plasterboard fixed to metal or timber framing, or mineral fibre acoustic tiles with a minimum NRC rating of 0.7.

Consideration must be given to acoustic treatment in rooms such as music/drama and technology. This may vary from exposed perforated insulation paper to proprietary-type ceiling tile systems and strawboard panels.

6.10.4 Paint

Use of APAS approved products

The cost of paint is only a fraction of the cost associated with the time and effort involved. The performance of paint can vary significantly from one product to another. For this reason products that have been approved under the Australian Paint Approval Scheme (APAS) are to be used.

Only low VOC (Volatile Organic Compound) paints should be used.

APAS tests and certifies paints and coatings to ensure they meet stringent performance specifications. The APAS “List of Approved Products” contains more than 2000 approved products



and is a comprehensive guide for specifiers. APAS lists include products with approved limits for volatile organic compounds (VOCs) in paints and coatings and do not include products containing lead, chromates or other toxic ingredients.

The basis of the scheme is the specifications prepared by APAS. Products are approved against these specifications and are required to be produced in APAS approved manufacturing plants.

Refer to APAS Document D184 Guide to Specifications, Supply and Quality Assurance (available on the web site http://www.apas.gov.au ) and Australian Standard AS 2311 Painting of Buildings.

To obtain a cross reference between the AS/NZS 2311 (Table 4.2) Paint Reference Numbers and the relevant APAS specification, it is necessary to refer to the APAS Document D 125. For example, Paint Reference Number B3 corresponds to Specification Number 0015/3, and these Specification Numbers can then be entered into the specification, shown below as an additional column to the Natspec Paint Type Table:

Preferred Materials

For general use, and particularly on exterior timber, latex (water-based) paints are usually favoured. Only low VOC (Volatile Organic Compound) paints should be used.

Solvent-based enamels are preferred for metal surfaces and those subject to wear and tear (e.g. doors, door frames, architraves, skirtings, painted window reveals).

Solvent-based semi-gloss enamel can also be used on internal walls.

Low-sheen acrylic (latex) can be used on internal walls.


http://www.apas.gov.au/


Full-gloss acrylic should be used for external walls.

Latex paints can usually be applied over existing solvent-based paints, although a latex undercoat may be necessary in more arduous situations. However, solvent-based paints should not be applied over latex types. Latex paint finishes are usually identified simply since they can be removed by a swab soaked in methylated spirits. Solvent-based paints remain sound under this test.

Colours

Light colours maximise the reflection of light and tend to make rooms seem larger, but often show marks.

Light colours should be applied to internal walls to maximise daylight benefit.

Darker colours are more serviceable in high wear locations such as skirting boards.

Smooth colour transitions from room to room are important in achieving colour harmony.

The completed paint job will look deeper in colour than a small sample, particularly when the same colour is used on all walls.

The colour of internal walls must be addressed in the Design Development report.

Gloss Levels

Flat and low gloss finishes best mask surface imperfections, but should be limited to areas not subject to wear and tear or moisture, such as ceilings.

Semi gloss (satin) is a compromise between masking defects in a surface and providing a serviceable, readily cleaned, finish.

Glossy finishes are preferred for surfaces subject to wear and tear, dirt retention, moisture, condensation, or frequent cleaning; notably architraves, cupboards, door, and metal work.

6.11 Acoustics

The acoustic design of a project is discussed in general terms in Section 4.4.9 – Acoustics. This section defines the acoustic design parameters and performance standards recommended for schools.

6.11.1 Statutory Requirements and Standards

Acoustic design requirements must be addressed in accordance with the following statutory requirements:

► “Occupational Health and Safety (Noise) Regulations Statutory Rule No. 10/2004” which specifies allowable noise levels in the workplace.

► “State Environment Protection Policy (Control of Noise From Commerce, Industry and Trade) No. N-1” (SEPP N-1) which regulates noise emission in metropolitan Melbourne.



► Australian Standards AS/NZS 2107 “Acoustics – Recommended Design Sound Levels and Reverberation Times for Building Interiors”. Within this Standard, Table 1, Section 1 provides recommendations for design sound levels in education buildings. It is recommended that these levels be achieved.

Occupational Health and Safety (Noise) Regulations Statutory Rule No. 10/2004

These regulations specify the allowable noise levels and noise exposure standards in the workplace. The allowable noise levels and exposure standards are applicable to all areas of the building that could constitute a workplace; however, they are most commonly relevant in workshops, technology classrooms, material preparation rooms and plant rooms.

A workplace must be designed to meet the following standards:

► peak noise levels no greater than 140dB(C); and

► an equivalent continuous noise level not exceeding 85dB(A) over 8 hours of a workday.

These are mandatory requirements.

Expert advice is generally required to determine if the above standards are likely to be exceeded. In most cases a noise exposure control strategy will be required to ensure compliance with the statutory standards. Noise exposure control strategies must be strictly in accordance with the requirement of the Regulations.

State Environmental Protection Policy No. N-1 (SEPP N-1)

This document defines procedures for determining mandatory noise limits applicable to any mechanical plant or equipment that may emit noise to a neighbouring noise sensitive location. A noise sensitive location can be a residence or a motel or a hospital or similar.

Expert advice is generally required to determine if noise from a school is likely to comply with the SEPP No. N-1 noise limits.

Noise sources that can lead to non-compliance include (but are not limited to) airconditioning equipment, exhaust fans and compressors.

Designers need to confirm that the project design will be compliant with SEPP No. N-1 noise limits.

AS/NZS 2107 “Acoustic: Recommended Design Sound Levels and Reverberation Times for Building Interiors”

This standard provides recommended design sound levels in a wide range of occupancies and includes recommendations for many room types that occur in educational buildings. This standard can be used or interpreted to define appropriate noise level design goals for spaces not specifically addressed by the Building Quality Standards Handbook.

It should be noted that the noise levels recommended in the standard apply to an unoccupied space and are not intended to cover noise from room occupants (i.e. voices).



This standard also provides recommended design reverberation times for a range of occupancies, and includes recommendations for many room types that occur in educational buildings.

6.11.2 Acoustic Floor Planning

Floor planning should include specific consideration of acoustic design requirements.

Spaces with opposite acoustic requirements should be located as far apart as is practicable. Examples include kitchens abutting classrooms, or music practice rooms abutting a library.

Where large open-plan teaching spaces are proposed, with no fixed walls between independent teaching activities, dedicated quiet rooms or pods should be included in the space planning to provide a facility for small groups who may need acoustic separation from the main group.

6.11.3 Sound Isolation between Spaces

The following information provides performance standards for the control of sound transfer between spaces via walls not containing a door.

Definition

The DnT,w rating is determined using Australian Standards AS ISO 140.4 and AS/NZS ISO 717.1. It involves assessment at site by measuring the noise reduction between rooms over a range of sound frequencies and then standardising the result.

Notes

1. With the exception of Category 1 (where rooms of two different categories abut), the division system should be based on the higher category.

2. Where any Category 1 room abuts a Category 2 or 3 room, the division system should be based on a Category 2 system.

3. Where any Category 1 room abuts a Category 4 or 5 room, the division system should be based on a Category 3 system.

4. The DnT,w performance is to be achieved taking account of all sound paths, including the ceiling void, floor, ductwork or ventilation openings, windows, perimeter wall junctions etc.

5. Music practice rooms should be designed to DnT,w 55 for all walls.

6. Any Category 3 or 4 walls dividing wet areas from any noise sensitive room shall incorporate plumbing noise attenuation measures. Plumbing noise attenuation should take the form of a double or staggered wall stud frame system. Pipes to the wet area should be fixed only to the studs that are supporting the plasterboard that is facing into the wet area.

7. Walls with Category 3, 4 and 5 performance should extend from floor to slab soffit or from floor to the roof soffit where there is a metal roof.

8. Walls with Category 1 or 2 performances should terminate at the underside of the ceiling. However, a positive and lasting acoustic seal must be achieved at the head of the wall.

9. In the case of Categories 1, 2 and 3, the ceiling system must not be of perforated or slotted construction, and would typically be 13mm plasterboard or a compressed acoustic tile having a thickness of at least 15mm and a weight of 4kg/m² or more.

6.11.4 Satisfactory Construction for Sound Insulation between Rooms

The following list provides descriptions of construction systems that can be deemed to satisfy the DnT,w performance recommended in Section 6.11.3.



Category 1

Wall Construction: Simple 64mm wide steel or 90mm wide timber stud with a single layer of 13mm plasterboard applied to each side.

Wall Extent: Wall may extend to the underside of any ceilings having a CAC (Ceiling Attenuation Class) of greater than 30 (examples include flush 13mm plasterboard and 15-18mm thick compressed acoustic tiles).

Cavity Insulation: Not required.

End Terminations of Other Walls: Standard building construction only. Termination to window mullions permitted but should be acoustically sealed.

Glazing: Permitted but must be sealed and should be at least 6mm thick.

Category 2

Wall Construction: As for Category 1 except that acoustic insulation should be placed in the wall cavity.

Wall Extent: The wall structure should project through the suspended ceiling, but framing and plasterboard layers need not extend to divide the ceiling cavity.

Cavity Insulation: Acoustic grade, 50mm thick with a minimum density of 14kg/m³.

End Terminations of Other Walls: As for Category 1.

Glazing: Not to make up more than 15% of the wall area, and must be sealed 10mm laminated glass.

Ceiling: Must have a CAC rating not less than 35. Must be overlaid with a 50mm thick, 24kg/m3 (minimum) density acoustic grade insulation for an extent of not less than 1200mm each side of the partition line.

Category 3

Wall Construction: Single 64mm steel or 120mm timber stud system lined with 2 x 13mm plasterboard on one side with 1 x 13mm plasterboard on the other side. Acoustic insulation is to be placed in the wall cavity.

Wall Extent: Wall system to interrupt the suspended ceiling with not less than a 1 x 13mm plasterboard layer extending across the ceiling cavity and being acoustically sealed around the perimeter.

Cavity Insulation: As for Category 2.

End Terminations of Other Walls: Walls should not abut window mullions, window glazing or simple lightweight partitions.

Glazing: Not recommended in these partitions.

Ceiling: Must have a CAC rating of not less than 30.



Category 4

Wall Construction: As for Category 3, however 2 x 13mm layers of plasterboard are required on both sides of the wall studs.

Wall Extent: All plasterboard layers to interrupt the ceiling and divide the ceiling cavity.


End Terminations of Other Walls: Wall structure should interrupt the flow of the lining of any flanking wall (e.g. sheets of plasterboard must not be permitted to pass uninterrupted past the end of the Category 4 wall).

Glazing: Not Recommended.

Ceiling: No specific requirement relating to sound transmission.

Category 5

Wall Construction: Two rows of 64mm steel or 90mm timber stud separated by not less than 70mm, and lined with 2 x 16mm plasterboard on both sides.

Wall Extent: As for Category 4.


End Terminations of Other Walls: Not to form junctions with any lightweight wall or facade system unless the structure of the abutting wall/facade is physically interrupted by the dividing wall.

Glazing: Not permitted.

Ceiling: As for Category 4.

As a general recommendation for all acoustically rated walls:

► Wall perimeters to be fully stopped and sealed.

► Walls are not to be degraded acoustically by penetrations for electrical or plumbing fixings or fixtures.

► Heads of walls terminating at the underside of suspended ceiling are to be sealed using compressible acoustic foam and/or flexible acoustic sealant beads.

► Walls dividing the ceiling cavity are to be sealed at the head, sides and at any and all services penetrations.

► Airconditioning and or ventilation openings in ceilings must not compromise the sound insulation between rooms and should be treated/modified accordingly. Where a duct penetrates an acoustically rated wall, it should be of steel walled construction and internally acoustically lined for not less than 1200mm each side of the penetration. The penetrating duct must be acoustically sealed into the wall penetration using a flexible non-hardening acoustic sealant.



6.11.5 Sound Isolation between Spaces and Connecting Doors

The presence of doors significantly limits the sound insulation between abutting rooms.

Walls with unsealed standard doors need not be rated above Category 2. However, the following performance standards are recommended for doors to occupied spaces.

Acoustic Seals

Type 1: Simple/standard compression seals applied to the head and sides of a ‘light weight’ aluminium or timber frame. No bottom seal.

Type 2: Light-duty non-adjustable acoustic seal rated to Dw 30 fitted to the head and sides of a stiff steel or timber frame.Type 3: As per Type 2; however, seal system to be adjustable and rated to Dw 32.

Operable Walls

Operable walls commonly require acoustic rating. Designers should establish the proposed use of rooms each side of the proposed operable wall and determine the acoustic rating using the Table in Section 6.11.3.

Operable walls capable of achieving a performance greater than Dw 35-38 are generally quite costly, and operable walls capable of the 35-38 range are commonly used between learning spaces.

Operable walls must be installed in accordance the wall system suppliers recommendations. The ceiling void above any acoustically rated operable wall must be divided using a solid baffle constructed with two layers of 13mm plasterboard on a suitable framing. The baffle must be fully sealed around its perimeter.

When selecting an operable wall based on laboratory ratings, it should be noted that it can perform in the order of 8 rating points lower when tested on site. Therefore if the wall is selected based on laboratory ratings, a rating in the order of 43 to 46 is required.

End termination of the operable wall should be reviewed and approved by the operable wall supplier or a qualified acoustic consultant prior to installation.

6.11.8 External Noise

Due consideration should be given to the appropriate design of the school building facade such that the recommended ambient noise levels tabulated in Section 6.11.7 would be achieved with windows and doors closed.

An appropriately qualified acoustic consultant should evaluate school sites that are impacted by noise from traffic, rail activity, commercial/industrial noise and/or aircraft noise. The results of the evaluation should be used as a basis for gaining advice on appropriate facade designs.

Noise from aircraft should be attenuated to the recommended noise levels set out in AS 2021.

6.11.9 Rain Noise

The design should specifically address the need to control excessive noise from rain in learning and speech use areas. Rain noise shall not exceed the ambient noise levels tabulated in Section 6.11.7 by more than 5dB(A) during a moderately heavy rain event (up to 25mm/hr rate).

As a basic requirement, (which does not necessarily meet the performance specification above) metal roofing should have a thermal/acoustic insulation blanket between roof purlins/battens and the roofing, which is at least 75mm thick.

Supply the school with a record of its trade waste application and plans.

7.4 Water Supply

7.4.1 General

The supply of water is governed by relevant Australian Standards as well as regulations and by-laws exercised through local water authorities. Victoria’s Safe Drinking Water Act 2003 (refer Department of Human Services) deals specifically with the regulation and quality of drinking water supplies.

The principal consultant will nominate which fixtures are “cold only” and which are “hot and cold”. In primary schools, hot water is generally supplied to the following areas:

► staff and administration areas;

► student showers;

► canteen;

► art room; and

► accessible toilets for students with disabilities.

In secondary colleges, hot water is generally supplied to all areas except student toilets.

7.4.2 Pipe Work, Valves and Fittings

Pipe work, valves and fittings shall comply with AS/NZS 3500. All pipe work in above-ground inaccessible spaces shall be copper tube “Type B” (insulated) in accordance with AS 1432 2004. Consider the use of flow restrictors and pressure reducing valves in a combined water and energy management system in order to reduce pipe sizes and headworks fees.

7.4.3 Tapware

Tapware shall generally be satin chrome finish with anti-vandal star pattern design handles. Cold-water handles shall be coded “blue” and hot-water handles coded “red”. Cold-water handles/taps



shall be fixed on the right-hand side of fixture and hot-water handles/taps fixed on the left-hand side. All tapware shall be of the same model and manufacture throughout a school. Tapware for later stages shall match the first stage.

Tapware for laboratories and other special-use areas shall be of a design suitable for the proposed use.

Tapware in sanitary facilities for people with disabilities must comply with AS 1428.1.

Water Efficiency Labelling and Standards (WELS) ratings must be provided for all tapware included under the current legislation.

7.4.4 Flow Rates (SWEP Requirement)

Under the Department’s Schools Water Efficiency Program (SWEP), water flow rates are set at:

► basins – 4 litres/minute (an exception is the sick bay at a permitted 6 litres/minute if the basin is the only tap outlet);

► classroom sinks – 6 litres/minute (exceptions are sick bays, home economics and science preparation rooms at a permitted 9 litres/minute);

► staff sinks – 6 litres/minute (exceptions are the main staff room and canteen at a permitted 9 litres/minute); and

► wash troughs – 9 litres/minute (exceptions are cleaners troughs at a permitted 12 litres/minute).

Refer also to Section 7.2 – Sanitary Fixtures.

7.4.5 Hot-water Units

Hot-water units shall be provided as required. These must be designed in accordance with AS 3500 Part 4 and AS/NZS 3500.4.

Hot-water systems must operate independently of space heating systems.

The design and selection of the most appropriate hot-water service supply will depend on the nature of the space, its location, usage and the activity therein. Hot-water units should be carefully sized and selected to match the anticipated demand for hot water. The oversizing of units will create excessive year-round energy waste and expense, and should be avoided. These matters must be addressed in the Design Development report.

A range of different systems may be appropriate, depending on the application, and include:

► gas storage units;

► continuous-flow gas or electric water heaters; and

► solar hot-water units.

Hot water shall be stored at a minimum of 60C to inhibit the growth of legionella bacteria.



In both primary schools and secondary colleges, all new hot-water installations, at the outlet of sanitary fixtures used primarily for personal hygiene, shall deliver hot water not exceeding 45C.

In selecting the most appropriate hot water supply, the following should be considered:

► Local storage units should be used for areas generating prolonged usage such as shower-change areas and science rooms.

► Natural gas domestic hot water units are to be used if natural gas is available on the site. Consideration for electric underbench heating could be given if excessive gas pipe runs are involved. Liquefied petroleum gas (LPG) should not be used at any site where natural gas is available.

► Continuous-flow electric water units should be considered in areas where short-term low quantity usage is required (e.g. staff tearooms) and no natural gas (only LPG) is available. These units should also be considered in other applications.

► The use of solar hot-water units (with a gas or electric boost) should be considered in areas of suitable climate. (Schools are currently eligible for Victorian Government rebates on the purchase of a solar hot-water heater.)

► Pressure equalising systems such as “Platypus” may be applicable in some large schools but they are not generally cost effective in systems using decentralised hot water to reduce hot water usage.

► The use of timer units should not be considered for gas systems since they are usually impractical, rarely cost effective, and often unreliable.

► The use of timer units for high efficiency boiling hot-water units are not cost effective given the good insulative properties of modern units and low out-of-hours electricity costs.

► Any timer controls should be centralised and connect back to a master multi-channel site clock.

► The storage capacity of water heaters shall be minimised as far as possible.

► All units shall be energy efficient and gas units shall have a 5 Star Rating Energy Label or better (and preferably electronic ignition). See Section 7.2.9 if boiling water units serve sinks, etc. Consider timers for shut down on holidays, weekends, night-time and curriculum days.

The selection of an energy-efficient domestic hot-water heater or the selection of solar hot water must be addressed in the Design Development report.

7.4.6 Water Supply Issues

The design of the water supply system shall address the following issues as appropriate:

► isolation of areas/fixtures by suitable valving to permit maintenance;

► provision of mixing valves where domestic hot water is supplied to personal hygiene outlets from storage water heaters;

► provision of backflow prevention devices to protect other areas from any hazard areas;

► provision of master control valve systems to demonstration benches;



► electronic taps for canteen wash basins;

► chrome plating on all exposed pipe work;

► provision of simple pressure-limiting devices to reduce overall water consumption;

► fitting of all showers with low flow heads; and

► consideration of the Department’s Schools Water Efficiency Program (SWEP) which may have requirements relevant to water supply design.

7.5 Gas Services

7.5.1 General

Gas services shall be natural gas or liquefied petroleum gas.

Completed installation shall be in accordance with AS/NZS 5601.1 and AS/NZS 5601.2 and the local supply authority.

In the selection of the most appropriate gas appliances, the following should be considered:

► gas appliances should have electronic ignition;

► gas appliances should be sealed combustion units;

► no atmospheric burners or pilot lights should be permitted;

► central plant shall have modulating heat output in response to changing load requirements;

► LPG should not be used at any site where there is natural gas;

► appliance thermostats shall be locked off from user alteration;

► units shall operate by simple on/off control or by time duration;

► local gas-heating appliances (ducted/space) shall be high-efficiency condensing units; and

► small space heating to offices or sick bays should utilise electric wall-mounted radiant panels unless central hydronic heating is available.

7.5.2 Connection Process

For new connections and gas supply upgrades, the plumber and/or gas consultant must contact the appropriate WoVG SPC Gas Retailer (currently AGL) to ascertain whether additional gas supply is available from existing gas supply assets. The retailer will in turn contact the gas distributor for that particular geographic area, and if there are any gas infrastructure works required, the gas distributor will provide to the gas retailer a quote and Supply Offer, with the retailer forwarding this quote and Offer onto the party making the initial inquiry. All quotes and offers should be forwarded to the SRAB for an independent assessment prior to signing.



Once the offer has been signed and forwarded back to the retailer, the works required will be completed. Consultants and plumbers must allow up to 60-days’ notice from the date of the initial inquiry to the proposed connection date.Email contact should be made with AGL at the following email address:

AGL Energy LimitedLocked Bag 14120 MCMC Melbourne VIC 8001

T: 1800 680 430F: 1800 634 823E: [email protected]

7.5.4 Tariffs

For new and existing projects, the estimated annual usage will determine the tariff assigned. Generally, there are two tariffs available:

► Tariff V - <10,000GJ per annum – is a bundled tariff, and the rates vary by Distribution Zone

► Tariff D - >10,000GJ per annum – is an unbundled tariff and subject to an offer from AGL at the current prevailing gas market price.

An assessment of the annual usage should also be undertaken to ensure that the correct tariff is assigned post-completion of the upgrade works.

For new projects, as the gas connection point will need to be rolled into the WoVG SPC, the following details need to be provided to the SRAB to enable it to arrange for the new gas connection to be added to the WoVG SPC:

► plumber’s name, telephone number and email address (if known at this stage);

► school name, telephone number and address (if existing school);

► principal’s name, telephone number and email address;

► MIRN (Meter Installation Reference Number) if known;

► any existing gas usage assessment reports where available, and copy of any communications with AGL.

7.5.4 Meters

Consider providing gas sub-meters to high energy-use areas and/or equipment (such as trade blocks but not kilns) in order to obtain energy-use profiles. This, however, is not a high priority.

7.5.5 Gas Supply to Relocatable Buildings



Where mains gas is provided to the site, consider a natural gas reticulation system to relocatable buildings described in the initial design, as well as branch take-offs for future additions.

If gas is to be provided to relocatable buildings, consider positioning the reticulation system in common services trenches with stormwater lines.7.5.6 Pipe Work – Above Ground

All above-ground permanent pipe work shall be “Type B” copper tube to AS 1432. All joints are to be brazed where practical. All pipe work is to be concealed from view in normally occupied areas. Provide protection from mechanical damage where exposed. Ensure adequate permanent ventilation to enclosed pipe risers. Provide isolation valves at each floor-level take-off. Allow 10% spare capacity in pipe work sizing. Where LPG is to be used and natural gas is likely to be available within five years, allow for natural gas in pipe work design.

7.5.7 Emergency Isolation Valves

Provide clearly labelled and accessible isolation valves within each room served with a general purpose fuel gas outlet. Locate valves generally adjacent emergency exits within that room.

7.5.8 Outlets

Provide fixed turret type outlets for laboratory bench-top use. Provide the demonstrator’s bench with an isolation valve to restrict gas supply to student outlets. Provide isolation valves and connect to each gas appliance.

7.5.9 Gas Booster

Gas booster devices are to be avoided where possible. Where required, locate carefully and ensure that adequate acoustic measures are provided to meet acceptable ambient and internal noise criteria.

7.6 Heating

7.6.1 General

Energy Design Process

A design process is to be undertaken which includes:

► a project meeting with all stakeholders and agreement to goals; and

► treatment of mechanical, electrical and building fabric design as the one exercise.

The most appropriate heating system for a particular application will depend on the nature of the space to be heated and the activity therein. A range of different systems may be appropriate, depending on the application. These include:



► power-flue console heater;

► high efficiency condensing ducted gas space heating (in conjunction with ducted cooling);

► reverse cycle airconditioning (where cooling is an entitlement);

► ground source heat pump;

► hydronic heating (hot water radiators);

► electrical radiant heaters (panel, tube); and

► gas radiant heaters (where ceiling height and government regulations permit).

Undesirable systems include:

► slab heating; and

► electric fan heaters (heat shifter fans may be considered in transferring heat to small areas such as offices adjacent to heated rooms).

System selection should take into account required amenity levels and employ a life-cycle process (over 15 years) to determine the most appropriate system based on total ownership costs.

Selection of a suitable system should be based on its ability to provide heating in an appropriate and adequate manner.

All plant is to be energy efficient and have a 5-Star Rating Energy Label or better if a star rating is available. The need for personal heating devices should be avoided through good design. Spot radiant heaters can be installed, if required, but only as a last option.

Ensure that plant is not over-sized and hence more expensive than need be or inefficient when operating at low capacity.

Energy Targets

No heating system should be installed until an energy target has been established and the performance of the proposed heating system compared against that target, and revised if necessary.

The mechanical services design and installation shall also be in accordance with the relevant Mechanical Energy Performance (MEP) industry standard guideline.

Building Design Considerations

No heating system shall be designed or installed until due consideration has been given to a satisfactory reduction of the heating load. Items to be considered include:

► orientation of building blocks, with their longer axis set out in an east/west direction;

► minimisation of areas of east-facing and west-facing glass (less than 5% of floor area each);

► external shading of east-facing, west-facing and north-facing windows;

► insulation of roof (both reflective and bulk), walls and floors (if timber). Insulation shall be made from a material that has a zero Ozone Depletion Factor (ODF);



► zoning of areas so that heated areas are grouped and isolated from non cooled areas by means of doors. If possible, heated areas should be separated from the outside by air locks; and

► location of doors, if possible, on the eastern side of the building to avoid cold southerly winds (as well as hot northerly winds).

Zoning

Consider zoning low occupancy areas separately for heating systems through the use of isolation valves and local heating controls.

Passive Solar Heating of Non Heated Spaces

Spaces not provided with fossil fuel heating (e.g. toilets, storerooms and corridors) should be heated with passive solar energy.

Ceiling Fans and Heating

The design of the heating system must include the use of high-efficiency ceiling fans. Ceiling fans operated slowly in conjunction with heaters help reduce energy consumption and should be installed so that the minimum height of the fan blades is 2400mm above finished floor level.

Daylighting and Heating

No heating system shall be designed until consideration has been given to reducing the internal heat load of electric lighting by maximising the use of daylight from shaded windows or skylights.

Installation Regulations and Standards

All installations must conform to the Building Code of Australia and comply with all relevant and current Australian Standards. These include but are not limited to AS/NZS 1668.1, AS 1668.2, AS 2913, AS 1677.2, AS 4254.1, AS 4254.2, AS/NZS 3000, AS 1324.1, and AS/NZS 3666.1.

Energy efficiency requirements of the Building Code of Australia may impact on selection of plant and equipment.

Fuel Source

As a general rule:

► use natural gas in preference to LPG and electricity;

► use natural gas in preference to LPG for the heating of relocatables; and

► do not use LPG when natural gas is available on site.

Plant and Equipment

All plant is to be energy efficient and have a 5 Star Rating Energy Label or better if a star rating is available. The need for personal heating devices should be avoided by good design. Spot radiant heaters are to be installed, if required, but only as a last option.



If possible, inside air should not be used for combustion.

Gas fired plant shall not produce unacceptable nitrous oxide (NO) pollution. Ensure that gas fired heating plants emit NO at a rate no greater than 200mg/kWh of delivered energy.

High efficiency condensing boilers should be used.

Ensure that centralised plant is capable of operating only when required to deliver heat. Out-of-hours use should be separately heated.

Ensure that plant is not over sized and hence more expensive than need be, or inefficient when operating at low capacity.

Gas plant should have electronic ignition.

Consider providing the following features to plant and equipment :

► heat recovery modules in heated areas where there are high ventilation rates;

► extra insulation on boiler if upgrades are being undertaken (modern boilers are often well insulated);

► local timer controls linked to a central time controller, with temperature sensing to avoid overheating;

► lockable and tamperproof thermostats; and

► insulating pipe work where hydronic systems are used.

If hydronic systems are used, ensure that the pipe work is well insulated.

Unflued gas heaters are not permitted except if gas radiant. Unflued radiant gas heaters remain a good option in spaces with high ceilings and large ventilation rates, e.g. trade and technology rooms.

The following table offers guidance on the recommended heating system types for selective areas within a school. It is a guide only, and the installation of any heating plant should be justified by the amenity required in the area. System selection should be based on a life-cycle analysis.

10 = Highest Cost

Filters

Filters are to have a design pressure drop of 25 Pa.

Filters are to be located so they can easily be removed for cleaning and replacement.



Return-Air Paths

Return-air paths reduce energy use in ducted air systems. Ensure that the return-air path is not subject to infiltration and is appropriately insulated.

Ductwork

Heating air ductwork is to be insulated to R1.5, well sealed, and designed to minimise air flow resistance. Ensure the return-air plenums are sealed. Do not use ceiling spaces for return air paths.

Outside Air Quantities

Where fan-forced ducted systems are used, outside air quantities should be minimised yet comply with ventilation regulations and provide appropriate indoor air quality levels.

Controls

All heating systems shall use simple yet effective controls to minimise the use of heating equipment while maintaining acceptable internal conditions. (Refer Section 7.6.5 for details.)

Sub-metering

All electric heating systems should consider the use of electricity sub-metering by blocks in order to easily carry out energy cost audits, including the cost of out-of-hours use.

Testing and Commissioning

Testing and commissioning should include two aspects:

► Firstly, the design should specify energy efficient equipment. Where appropriate, testing and commissioning should confirm this performance.

► Secondly, documents should ensure the handover of accurate and detailed building and systems records and operational directions. Such documentation should not only set out details of the installation and its energy efficient operation but also clearly record all design assumptions and capacities in order to facilitate future modifications and building adjustment.

If appropriate, provide a certified air distribution and diffusion test report which includes an adjustment and balance report. For hydronic systems, include a water balancing report.

Maintenance Strategy

Consultants shall provide an ongoing maintenance strategy for later implementation by the school.

7.6.2 Centralised Plant versus Individual Units

Consideration should be given to the following factors when considering centralised plant:



► warm up time;

► room occupancy patterns (primary school rooms are generally occupied by the same people while secondary colleges are subject to continually changing and varying occupancy);

► control systems;

► efficiency of systems, particularly in part load circumstances;

► solar gain, especially in north facing rooms; and

► zoning of building.

Ensure that centralised plant is capable of operating only when required to deliver heat.

Where spaces are to be used out-of-hours they should be separately heated.

7.6.3 Primary Schools

Unitary gas heaters should be used for classrooms and larger spaces, and include convective powered flue or wall furnace types. Radiant gas consoles or wall-mounted heaters should not be used in these areas.

Ducted warm-air furnace heating may be considered, depending on architectural floor plan and building construction.

Ducted warm-air furnace heat should be used for administration and staff areas.

Wall-mounted gas radiant heaters should be used for large volume spaces with high ceilings (e.g. halls).

High-level wall-mounted or ceiling radiant electric heaters could be used where floor/wall space is limited (e.g. canteens).

Toilets, storerooms and corridors should not be heated other than through a spill-over from adjacent areas.

Unitary space heater locations should aim for even heat distribution and be sited away from corners and close to cold parts of the room (e.g. windows). Layouts should allow 200mm both horizontally and vertically from walls, fixed furniture, pin boards, etc. and around floor-level heaters for safety and maintenance. Allow a space of at least 1000mm horizontally from the heater to nearest occupant.

Independence of main systems in areas to be used out-of-hours should be considered.

7.6.4 Secondary Colleges

Designers should consider potential vandalism to heating systems when preparing designs for classrooms.

Central heating systems with re-circulating air or return-air should be used except in rooms where dust, fumes or odours are generated.



Toilets, storerooms and corridors should not be heated other than through a spill-over from adjacent areas. Physical education centres should be heated only when directed.

Independence of main systems in areas to be used out-of-hours should be considered.

7.6.5 Heating System Controls

Control systems should have a centralised master time clock to ensure after-hours switch-off as well as local controls allowing variations to suit local conditions. Time clocks with temperature sensing will help avoid overheating.

The thermostat setting should not be higher than 19°C.

Heater controls should be student tamperproof and accessible only by a key. Thermostats should be lockable and tamperproof.

Where appropriate, heating controls should take into account climatic conditions and allow for early morning warm up to modulate temperature according to space conditions. Heating controls should also take advantage of internal heat generated by occupants and office equipment.

Control systems should accommodate power failure and ensure that the resetting of the system is a simple procedure.

Spot radiant heating should be controlled by local time switches (45 to 60 minute maximum operating times are recommended before a restart is required).

7.6.6 Gas-Fired Plant

If possible, inside air should not be used for combustion.

Gas-fired plant must not produce unacceptable nitrous oxide (NO×) pollution. Ensure that gas-fired heating plants emit NO× at a rate no greater than 200mg/kWh of delivered energy.

High-efficiency condensing boilers should be used.

Gas plant should have electronic ignition.

Unflued gas heaters are not permitted except for radiant gas heaters. These heaters remain a good option in spaces with high ceilings and large ventilation rates (e.g. trade and technology rooms).

7.6.7 Water Heating Boilers

Boiler Types



Boilers should be designed and installed in accordance with Australian Standards AS 1375, AS 4552 and AS 3814.For gas-fired boilers, provide controls that allow for automatic ignition and stopping. The Building Code of Australia may require some boilers to be fire-enclosed and separated from the building.

Air Supply

Provide combustion and ventilation air to suit the boiler. Arrange for it to be unaffected by adverse influences such as cross drafts and negative pressures.

Water Supply

Provide feed water and expansion tanks with capacity to accommodate the expansion of water contained within the boilers and the associated piping system. Do not fit valves between tanks and boilers.

Piping

Provide piping sized to permit the free movement of liquid and gases.

Plinths

Boilers should be mounted on concrete plinths.

Flues

Provide a separate flue to each boiler. For pressurised boilers, do not discharge multiple flues into a single flue. Support flues to compensate for thermal expansion as well as flue weight, wind loading and other imposed loads.

Provide a removable base or access covers for flue cleaning and inspection. Provide a trapped drain at the base of each flue and pipe to waste.

The minimum flue exit velocity at full load should not be less then 15m/s.

For gas-fired boilers, insulate the flue to the point of exit from the building.

7.6.8 Plant Rooms

Avoid fully or partially underground plant rooms.

Boiler and furnace plant rooms should be exclusive to that purpose.

Where possible, the plant room should have at least one external wall. Access to the plant room should be from outside or from a corridor. Access should not be from a store, wet area or any area likely to contain flammable substances.



7.7 VentilationVentilation is useful in reducing the overheating of large spaces, especially where numbers of students gather. Ventilation is also useful for overnight cooling.

The main requirement under the Building Code of Australia is the provision of fresh air to all occupied areas by way of natural or mechanical ventilation.

For school airconditioning, assessment of fresh air provision must be based on either fixed openings or open-able devices such as doors and windows that are directly connected to the outside of the building. The Building Code of Australia requires that this be a minimum area proportional to the occupied room floor area. Typically the minimum area of fixed or open-able devices must be 5% of the total floor area. If the above area of fixed or open-able devices can be achieved, the room is deemed to comply with the natural ventilation requirements of the Code.

If the natural ventilation requirements of the Code cannot be met, then outside air must be supplied to conditioned spaces at the rate set down in Australian Standard AS 1668.2.

7.7.1 Energy Targets

If cooling is proposed, no natural ventilation system should be installed until an energy target for the building has been established and the performance of the proposed cooling system compared with that target, and revised if necessary.

7.7.5 Kiln Exhaust Systems

Size hoods to cover kiln openings and discharge points.

Manufacture the hood from 1.6mm thick galvanised mild steel sheet.

Ensure an adequate make-up of exhaust air quantity.

Provide a local manual control station adjacent to the hood and complete with a LED-run indicator.

7.7.6 Fans

Fresh Air Fans

Provide fans that have quiet operation, deliver the required air quantity against the resistance of the system as installed, and have a maximum static efficiency at the required duty.

At the time of initial design and fan selection, degradation of the fresh air filters over time should be taken into account.

Ensure all components are corrosion and weather resistant.

Ensure that fans are statically and dynamically balanced.

Provide one control station per fan with a minimum of three speed settings in forward and reverse direction. Controls should be of commercial quality to withstand robust usage.

The minimum height of ceiling fans (as measured from the underside of the fan blades) shall be 2400mm from finished floor level. To ensure adequate movement of air, do not install fans too close to the ceiling.

Mount fans clear of lights to avoid stroboscope effect.

Provide sweep fans on the basis of one fan per 25m² of floor area. They should feature time-out controls so that they only operate when required.

For upgrade projects, consider the replacement of ceiling fans installed prior to 1980.

7.7.7 Air Filters

Filters should be selected and installed in accordance with AS 1324.1.

Select filters that are odourless, non-toxic, non-migrating, non-evaporating, non-hardening, resistant to microbial growth, and which do not shed fibres in service.



Rigidly attach filter frames to the air-handling plant casing (such as duct, or return-air plenum) with a system of bolting or blind pop riveting. Locate bolts or rivets clear of the filter element. Do not fix to the casing insulation. Ensure that the installation of the filter does not reduce its rated performance.

Ensure that individual filter inspection and maintenance can be readily carried out without disturbing the filter bank.

Ensure that there are no leaks between the filter-holding frame and the casing to stop air bypassing the filter media. Frames should be capable of withstanding distortion arising from the final pressure drop across the filter.

Permanently and legibly mark, on a suitable section of the filter, the following:

► filter type and class;

► direction of airflow;

► proprietary type, model and serial number; and

Before start-up, ensure that the installation is free from debris and dirt, and check the integrity of the filter bank and plenum installation.

7.7.8 Ductwork

Standard Ductwork

Ductwork should be designed, installed and constructed in accordance with AS 4254.1 and AS 4254.2. The Building Code of Australia requires supply air and return air ductwork to be insulated.

Rigid Ducting

Fabricate ductwork and fittings from galvanised steel sheet, machine bent and free from waves and buckles. Remove burrs and sharp edges and ensure that there are no protrusions into the airways.

Provide supports at 2400mm maximum centres for ducts up to 3000mm in external perimeter and at 1300mm maximum centres for larger ducts. Supports should be provided adjacent all changes in direction to fix the ductwork in position and prevent noticeable sag.

Ductwork exposed to weather is to be constructed and installed as follows:

► Seal all exposed ductwork joints through the use of watertight protective shields. Seal all duct supports where they attach to the duct, and seal all reinforcement attachments so that moisture cannot be retained in any gap or crevice.

► Profile or cover the top side of ductwork exposed to weather to shed water.

Provide ductwork insulation in accordance with the Building Code of Australia.



Flexible Ducting

Flexible ducting should be an “acoustic” type fabricated from a helix of zinc coated spring steel wire, lined and jacketed with perforated aluminium laminate, and insulated with 25mm thick fibreglass jacket with aluminium laminate to achieve a “4 zero” rating.

Use outlets and grilles that meet noise level requirements for occupied spaces.

Grilles should be constructed out of aluminium and have a thermostat powder coating finish to AS 3715. Dampers and visible ductwork behind the grilles should be painted matt black.

7.8 Cooling

7.8.1 Preliminary Note on Thermal Comfort and Cooling Policy

The Department is considering the introduction of new maximum and minimum thermal comfort standards. An associated element will be the implementation of energy efficient design. A detailed investigation is currently underway, and pending the release of further information, this version of the Handbook applies.

7.8.2 General

The minimisation of overheating is integral to the successful utilisation of school buildings. Design and installation factors which contribute to the thermal comfort of a facility include its orientation and external shading, its wall and roof insulation, natural ventilation and the use of ceiling fans. Where, because of climatic extremes, a combination of these factors is inadequate in maintaining comfortable room temperatures, cooling systems are installed.

Cooling systems are provided to schools on the basis of their location within the Nationwide House Energy Rating Scheme (NatHERS), zones 20 and 27 (refer Appendix 3 – Postcode Areas within NatHERS Zones). All schools in these areas receive airconditioning to their entitled spaces under the space and area guidelines. The remaining schools are not provided with cooling systems except in a limited number of circumstances, e.g. where a concentration of mainframe equipment is located. Airconditioning is to be provided to all special developmental schools.



Selection of Cooling System

The most appropriate cooling system for a particular application will depend upon the nature of space to be cooled and the activity therein. A range of different systems may be appropriate depending on their application. These include:

► evaporative cooling; and

► refrigerated air cooling, including split airconditioning or console units as well as packaged units.

System selection should take into account the required amenity levels and employ a life-cycle analysis process (over 15 years) to determine the most appropriate system based on total ownership costs.

Selection of a suitable system should be based on its ability to provide cooling in an appropriate and adequate manner. Life-cycle analysis of systems that meet the amenity criteria should address:

► capital cost including associated infrastructure costs such as electric sub-mains;

► maintenance costs for a realistic life of the system and its components; and

► energy costs on the basis of likely energy tariff rates, envisaged usage requirements (climatic demands and hours of operation) and the ability of a particular system to be controlled in such a way as to match its operation time to actual occupancy requirements.

The following table offers guidance in the selection of cooling systems for various school areas where cooling is required. It is a guide only, and the installation of any cooling plant should be justified by the amenity required in the area. The system selected should be based on a life-cycle analysis.

Natural Ventilation

No cooling system shall be considered, designed or installed until the use of natural ventilation has been considered.

Daylighting and Cooling

No cooling system shall be designed or installed until consideration has been given to reducing the internal heat load of electric lighting by maximising the use of daylight from shaded windows or skylights.

Sub-metering

All cooling systems should consider the use of electricity sub-metering (by blocks) for cooling in order to carry out energy cost audits, as well as the costing of out-of-hours use.

Testing and Commissioning

All installed systems should be tested and commissioned in accordance with the manufacturers’ recommendations to ensure that they work as specified.

Maintenance Strategy

Consultants should provide an ongoing maintenance strategy (including documentation) for use by school in relation to all refrigerated and evaporative coolers.

7.8.3 Evaporative Cooling

General

The design and installation of evaporative coolers should be in accordance with AS 2913.



The cooler capacity should be based on a minimum of 35 air changes of the room volume served. Design air change rates vary throughout the State. Check with the cooler manufacturer for the recommended air change rate.

The design of the building must provide sufficient openings to discharge the large volumes of introduced air.

The unit casing shall be either stainless steel, marine grade aluminium or stabilised UV resistant polymer with a suitably matched fibre glass or polymer water sump. Capital cost and operating environment shall be taken in to account when selecting the unit. All components (including the fan, pump and motors) shall be non corrosive and suitable for operation in a moist environment.

Noise generation should be considered when selecting an axial or centrifugal fan unit.

Each unit should be provided with a water sump dump valve to flush out sludge and concentrated salts. The sump bleed and drain valve discharge pipe shall not discharge onto metal roof surfaces but be piped to the nearest stormwater down pipe.

Smaller downwards discharge coolers may be supported off the rigid supply air duct. A suitable corrosion resistant support frame off building members for larger units should be supplied.

Filters

Filters should be easily removable for cleaning.

Ductwork

Internal duct insulation shall be moisture resistant or contain a moisture resistant membrane. Flexible duct external insulation of glass or mineral fibre should be a minimum of 25mm thick.

The use of attenuated ductwork should be considered. The length of ductwork should be minimised.

Automatic dampers to close units when not in operation should be provided.

Controls

Each evaporative cooling unit shall have a variable or multiple fan speed controller, an ON/OFF pump controller, and automatic dump valve operation.

The thermostat setting should not be lower than 24°C.

Time-delay and time-control switches should be considered. Controllers should be linked to a central time clock.

Water Supply

Local water supply should be taken into consideration when supplying the units. A water treatment plant may be required in some hard water areas.



Consideration should be given to evaporative coolers only in locations where there is reticulated town water. In other locations, refrigerative coolers should be provided.

Installation

An adequate and permanent means of access and an appropriate platform for servicing units should be provided.

A hose spigot point adjacent to the unit is to be provided for unit cleaning.

Servicing Schedule

7.10 Electrical Lighting and Power

7.10.1 General

Life cycle analysis of systems which meet the amenity criteria should address:

► capital cost, including associated infrastructure costs related to electric sub-mains, metering and control gear;

► maintenance costs associated with a realistic life of the system and its components; and

► energy costs on the basis of likely energy tariff rates, envisaged usage requirements (climatic demands and hours of operation) and the ability of the lighting system to be controlled in such a way as to match its operation time to occupancy requirements.

This analysis must distinguish between <160MWh per annum and >160MWh per annum sites, and be easily accessible for use by the Department’s Schools Resource Allocation Branch (SRAB) and post-commissioning audits. It must state the Whole of Victorian Government (WoVG) state purchase contract rates used for <160 sites as well as WoVG energy rates and network tariffs applied at >160 sites.

Where schools have existing equipment/components, every effort shall be made to match brands of equipment/components.

All external fittings will need to be vandal-resistant and tamper-proof. The extent of protection will be based on the security level of each school.

Electrical systems need to be provided for normal operating conditions in Victoria.

An ESD consultant should be engaged as part of the design team in matters pertaining to ecologically sustainable design (ESD). As a minimum, the design should meet the requirements of the Building Code



of Australia Section J.

7.10.2 Design

It is important that lighting be considered in two forms: natural and artificial. For natural daylighting, the correct sizing and location of openings is the key factor. For artificial lighting, the correct sizing and location of energy efficient equipment and control systems is important.

Design and construction should minimise the fossil fuel required to provide acceptable indoor light levels. Factors which will assist this include:

► Fabric and ServicesAn awareness that the windows and skylights (the building fabric) and the artificial lighting (the services) both contribute to energy efficiency and are inseparable considerations.

► ZoningThe building should be zoned into different lighting and control zones depending on the closeness to windows and skylights, and the tasks required to be performed.

► Energy TargetsEnergy targets should be set for each project.

► Circuit DesignWhen utilising daylight, the lighting circuit should be designed to minimise artificial lighting. Circuitry should allow for night time use as well as maximum daylight availability.

Where there are high levels of equipment (such as in staffrooms), consideration should be given to the creation of two circuits within the general purpose power circuit design. This would accommodate both 24 hour supply and supply which switches off after hours.

► Powerline Carrier SystemsPowerline carrier systems are not currently recommended because of their present unreliability.

7.10.3 Supply – General

The provision of incoming supply needs to be carefully planned with future developments in mind and be brought to the attention of the supply authority at the first instance when future capital works programs are known. Assumptions made in determining load (i.e. usage, demand and the infrastructure required) must be clearly stated, as must any variations received after an offer from a distributor, before signing an agreement (“supply offer”) with that distributor.

Designers need to adequately size mains and submains to include sufficient capacity for planned future stages of school developments on the same site, including all relocatable buildings necessary to meet peak enrolments. Power pillars within close proximity to the proposed relocatable complexes to be considered for the provision of power to these complexes.



The Department is a participant in two Whole of Victorian Government (WoVGS) state purchase contracts (SPC) for the supply of electricity to all schools. A decision on which contract is applicable for a new site (meter) or for a new connection in the upgrade of an existing site will be dependent on the estimated annual usage and, in the case of larger schools, the likely electricity load or demand at the site. Current SPC suppliers are:

► Red Energy, for all sites with an expected annual usage of >160MWh (refer Section 7.10.4); and

► Powerdirect (a subsidiary of AGL), for sites with an expected annual usage of <160MWh (refer Section 7.10.5).

7.10.4 Red Energy – For all sites with an expected annual usage of >160MWh.

Note that sites which require installation of new substations (kiosks) are likely to be the subject of an agreement (“supply offer”) with the local distributor, and would normally join this contract.

New Connections

In helping to identify electricity infrastructure requirements, it is strongly recommended that an energy engineer (refer Section 4.8.1 – Energy Engineer), or person responsible for this function, make early contact with the local distributor to determine cost-efficient site infrastructure and network tariff. It is critical that the energy engineer be in no doubt as to what network tariff will be applied in the offer made by the distributor.

Sites supplied under this contract will receive an unbundled bill that will separate the retail energy component from distributor charges (i.e. network tariffs) which are passed on, on behalf of the distributor, by the retailer.

A key component of the network tariff may be a “minimum demand” component. To ensure that schools are provided the most cost-efficient tariff within their particular circumstance, an Energy Cost Worksheet (ECW) summary, signed-off by the energy engineer, should be used as the basis of calculation.

The following guidelines are recommended in confirming ECW calculations and abetting discussions with distributors prior to the signing of any agreement (“supply offer”).

Network Tariffs

The impact of a minimum demand network tariff on future energy costs should be considered when planning a new facility. For new and upgrade projects (and prior to the signing of a formal agreement with the distribution business), review the network tariff proposed and ensure that it is advantageous to the school from an operational and cost perspective. This review must take into account the short and longer term impact on both capital and recurrent costs, particularly at new and growing schools.

All design must meet the maximum demand assessment of the local distribution authority. Any differences between this and the initial assessment prepared by the electrical consultant must be



resolved prior to the presentation of the EWR (Electrical Works Request) to the retailer by the REC (Registered Electrical Contractor).

It is imperative the “person responsible” ensures that information contained in the EWR (and in particular, related to load) is consistent with what has been agreed to and signed with the distributor. Any differences must be resolved prior to it being submitted to the retailer. This is necessary since agreements are often signed more than 12 months prior to an actual commissioning based on the EWR.

Agreements (“supply offers”) provided by the local distribution authority must be reviewed by the builder and the electrical contractor prior to quoting for this aspect of the project.

To assist in this process, the Department has arranged for an independent assessment of all calculations related to maximum demand for new and major refurbishment projects affecting electrical works. It is recommended that this service be utilised. A fee may apply for this assessment. The following process will apply:

Consulting Stage

1. Architect to contact the Department’s Schools Resource Allocation Branch (SRAB). by email to obtain the contact information for the independent assessment.

To allow for the independent assessment to be completed, the following information must be provided:

► outline of project, including any planned stages;

► architect’s name, telephone number and email address;

► electrical consultant’s (energy engineer’s) name, telephone number and email address;

► electrical contractor’s (REC) name, telephone number and email address (if known at this stage);

► school name, telephone number and address (if existing school);

► principal’s name, telephone number and email address;

► national metering identifier (NMI) if an existing supply, meter number (if existing school);

► advice as to whether the existing supply point will be upgraded/altered, or new supply point is required;

► existing site – copy of a recent invoice;

► any existing electrical audit report (for existing installations); and, where available,

► copy of any communications with the local distribution network company.

2. Existing sites with an estimated usage of >160MWh per annum, and where Red Energy is not the retailer, should be transferred to Red Energy immediately by contacting the SRAB.



Where Red Energy is the retailer under the state purchase contract (SPC), the consultant can arrange to obtain the 30-minute data by contacting the SRAB to confirm existing maximum demand and provide information back to the architect/electrical consultant.

3. New sites with an estimated usage of >160MWh per annum, or with a load that requires a minimum demand network tariff, must be added to the >160MWh per annum state purchase contract (SPC).

4. The electrical consultant’s calculations of estimated usage and maximum demand for new works are to be sent to the contact provided by the SRAB assessment for review and to verify assumptions.

5. Where issues are identified, the independent assessor will discuss and resolve issues with consultants and architects.

6. Electrical consultant to request from local distribution authority a “Supply Offer” based on confirmed estimated maximum demand.

7. The Supply Offer is to be forwarded to the SRAB who will arrange for an independent assessment to confirm ratings and identify all costs. The independent assessment will provide a summary report to all stakeholders (There is no cost associated for this.).

Sign off By Principal

Sign off by the school principal.

Tender

Submit all necessary electricity “Supply Offers” in tender documentation.

Construction and Submission of Electrical Works Request (EWR)

The independent assessment will compare with existing proposal. Any difference must be highlighted and a brief explanation provided.

Once the EWR is finalised, the Registered Electrical Contractor (REC) must submit the EWR to Red Energy via email to any of the following contacts at least 20 business days prior to the date that the connection is required:

Michelle Hertaeg ([email protected])

Kimberley Barnett ([email protected])

Manmeet Korala ([email protected])

Telephone number for above contacts is: 03 9425 0590



7.10.5 Powerdirect – For sites with an expected annual usage of <160MWh.

Sites supplied under this contract will receive a bundled bill based on the applicable Powerdirect state purchase contract tariffs (e.g. E, E1 or D) for the relevant distributor’s area.

The school (or superintendent) is required to engage a registered electrical contractor (REC) in order to have the relevant Electrical Works Request (EWR) and Certificate of Electrical Safety (CES) completed. This information must then be forwarded via fax or email to Powerdirect New Connections, attention Shona Wales, MAC Specialist, tel: 03 8633 6823, fax: 03 8633 7402, email: [email protected]

Once any electricity works have been completed, schools in this category should carefully monitor consumption over a period of 3-6 months to determine if there is a likelihood that it might exceed 160 MWh per annum, in which case they should contact the Department to determine whether supply should move to the >160 MWh per annum contract.

It should be noted that once a new metering connection is completed, an account under the WOVG contract will be created in the school’s name which then generates ongoing invoices for usage. It is imperative that in the submission of a new metering request, agreement is reached with the builder, project manager and school as to who is responsible for paying invoices up until the school/building is handed over.

Green Power

The purchase of green power will be in accordance with Department guidelines and is an automatic inclusion in both the above contracts.

Meters

Provide electrical meters on a per-block basis to individually measure lighting, power and plant Provide subsidiary electrical meters on a per-block basis to allow individual measurement of lighting, power and plant usage so that energy use profiles can be easily obtained.

Each of the above contract retailers will arrange for the installation of appropriate metering for billing purposes only and not subsidiary meters.

Photovoltaic Metering

In the case of a solar installation, schools should ensure that the installer has received approval from the local distribution authority prior to installation.

Once approval from the local distribution authority has been received and the solar installation has been completed, the installer must contact the current WoVG SPC electricity retailer and provide all necessary paperwork to allow for a reconfiguration of the billing meter to register energy that is excess to school requirements and exported back to the grid.



For further information regarding all WoVG SPC energy contracts, please contact Brett Duff, Schools Resource Allocation Branch (SRAB), tel: 03 9637 2063, fax: 9637 2440, email: [email protected]

7.10.6 Main Switchboard

Design

Equipment and conductors shall have a short-circuit rating of not less than the maximum prospective symmetrical RMS short-circuit current values on incoming terminals at the operational voltage.

The short-circuit rating shall withstand fault currents for a minimum of one second.

The degree of protection required shall be IP20 for internal installations and IP54W for external or plant room installations.

Provide at least 25% spare capacity in the ratings of main incoming busbars and main switch/isolators, and 25% spare capacity for extra sub-circuits and circuit breakers.

Ensure there is sufficient capacity in the switchboard for planned future stages of school development, including all relocatable buildings necessary to meet peak enrolments.

Switchboards and associated electrical conductors must be protected by fire-resisting construction (refer Building Code of Australia, clause C2.13).

An emergency luminaire should also be considered above the location of the switchboard to facilitate safe viewing in the event of partial power failure.

Location

Locate the main switchboard to suit the layout of the site, taking into account the following:

► easy access for supply authority meter reading;

► minimising the consumers’ mains cable length;

► centrality of the switchboard to electrical loads served; and

► its access for maintenance without undue disruption to the operation of the school.

The main switchboard is generally located in the administration area because of its central location and function. An emergency luminaire should also be considered above the location of the switchboard to facilitate safe viewing in the event of partial power failure.

Switchboards located in a path of travel to an exit must have a non-combustible smoke-proof enclosure in order to comply with the Building Code of Australia.

7.10.7 Distribution Switchboards

Generally, the same conditions apply as in Section 7.10.2 with the exception of the following:



► miniature DIN rail-mounted fault-limiting circuit breaker switchboards should only be installed. Separation shall comply with Form 1 of AS/NZS 3439.1;

► fault rating of busbars shall be calculated at the incoming termination of the distribution switchboard but at not less than 18kAmp/second;

► where RCD protection of general purpose outlets is required, this should be provided at the relevant circuit protective device within the distribution board; and

► specify the maximum number of general purpose outlets or final sub-circuits per RCD device.

Spare capacity should be included in the switchboard for planned future stages of school development. Distribution switchboards and associated electrical conductors must be protected by fire-resisting construction (refer Building Code of Australia, clause C2.13).

7.10.8 Wiring

As teaching spaces may alter from time to time, consideration should be given to designing a flexible support system for cabling in a variety of configurations.

Cables need to be concealed for safety reasons. Systems such as skirting duct, wall duct, floor duct and service columns should be considered to avoid tripping hazards. Exposed cabling is not acceptable.

Provision for future additional cabling should also be taken into account.

All cables shall be double insulated (i.e. PVC, XLPE-insulated with a PVC sheath), MIMS or fire-resistant polymer insulated and sheathed. Single insulated “building wire” will not be accepted.

Copper conductors shall be multi-stranded and not less than 1.5mm2 for lighting or 2.5mm2 for power final sub-circuits.

Cables with conductor sizes greater than 35mm2 per phase shall be single core double insulated with a multi-stranded conductor.

Cables should be sized to carry the intended electrical load, taking into account the maximum demand, methods of installation, short circuit capacity and voltage drop. Utilise AS 3008 Part 1 when sizing cables. 7.10.9 Power and Special Connections

General Purpose Outlets

All general purpose outlets (GPOs) shall be connected to a final sub-circuit and protected by an ELCB (RCD) rated at not more than 30mA.

Measuring Lumen Maintenance of LED Light SourcesLight Sources



All lighting installations shall comply with the requirements of Section J of the Building Code of Australia.

Provide instant re-strike high-efficiency light sources such as T5 or LED lamps. Install special purpose lamps and luminaires in special areas (i.e. photographic laboratories, media rooms, etc.) as required.Fluorescent lamps shall comply with AS/NZS 4782.1, Minimum Energy Performance Standards (MEPS) and be 16mm diameter (T5), triphosphor lamps.

Luminaires used in conjunction with T5 lamps shall be of a design originally intended for the T5 lamp. T5 retrofits for existing fluorescent luminaries are not acceptable.

The use of linear LED replacement tubes in existing fluorescent tube fittings is not recommended. It is recommended that existing T8 and T12 fluorescent tube type fittings are replaced with new energy-efficient T5 fluorescent tube or LED fittings when schools undertake energy-efficient lighting upgrades.

If linear LED replacement tubes are used, the existing fitting must be in good condition. There is a risk that the replacement tube may fall out if the existing fitting is in poor condition. LED replacement tubes can also have a lower light output than the fluorescent tubes being replaced. Existing fluorescent tube type fittings need to be modified by an A grade electrician for the LED replacement tube to work.

Bare or exposed lamp luminaires are only acceptable if permitted by the following table and fitted with wire guards. All luminaries shall have photometric files to NATA accreditation and EMC compliance as per Australian Standards. Where a prismatic lens is used, a minimum of Y19 is recommended.

Light emitting diodes (LEDs) shall be manufactured by a reputable manufacturer such as Cree, Osram, Nichia, Tridonic, Xicato or Luxeon with proven experience in LED production. The luminaire manufacturer shall meet any certification available by the LED manufacturer.

LEDs and drivers in fittings shall be replaceable. This is to avoid the need to dispose of the whole fitting in the event of LED fault or failure.

LED light engines shall preferably conform to Zhaga Interface Specifications (current edition of relevant Book). Certification is preferred but not mandatory provided the supplier can prove certification is underway, or the inherent interchangeability and replaceability of the offered product in accordance with Zhaga Interface Specification Books.

If Zhaga is not an adopted protocol of the nominated manufacturer, then a modular replaceable LED engine system must be used, and information provided to the lighting consultant to define this. No LED products will be used without replaceable LED engine systems, unless specifically detailed as an exception in the project scope of works.

LED light engines shall comply with the following safety and performance standards:

A common style of lamp should be used throughout the project, thereby minimising the requirement to store different lamp types for maintenance.

Reflectors, where required, shall have a total reflectivity of at least 80%.

If downlights are required, select LED or compact fluorescent types. Air space shall be provided around the downlight in accordance with the manufacturer’s recommendations or a suitable surface mounted luminaire should be selected in its place.

The expected service life of a typical luminaire is 15 years; consider the replacement of any luminaires older than this.

For renovations, consideration should be given to the relocation of existing luminaires into lesser utilised areas (in conjunction with motion sensors) and the installation of new technology luminaires (for example, LED) to capitalise on energy efficiency and reduced maintenance.

In larger areas with higher ceiling heights, consider the following solutions;

► Metal halide luminaires – observing the following ‘rule of thumb’ minimum mounting heights to avoid excessive glare;

o 70 watts – above 3 metres




► High-output T5 luminaires for ceiling heights above 5 metres

LED luminaires – observe manufacturer’s recommendations regarding mounting heights.

Ballasts

Electronic ballasts for fluorescent luminaires shall: comply with AS/NZS 4783, AS/NZS 60928, AS/NZS 60929, AS/NZS 61347 and AS/NZS 3100; have a Ballast Energy Efficiency Index of A2 (if switched) or A1 (if dimmed); have a Ballast Lumen Factor of 1.0; and be rated for 50,000 hours of operation at 50 degree C (in the ballast chamber).

Subject to a cost/benefit analysis, dimmable ballasts may also be considered in conjunction with daylight sensors.

Auditoriums and halls should consider 0-100% dimming for effect and/or energy efficiency in relation to the task.

Illumination Levels and Glare Indices

Illumination levels and glare ratings shall be in accordance with the Recommended Design Criteria



Table p. 119.The aggregate design illumination power density expressed in W/m² must not exceed the sum of allowances specified in Section J6 of the Building Code of Australia after taking into account the applicable control credits.

Switching groups (whether by manual or automatic devices) must not exceed 100m² of floor area.

Arrange luminaires to provide general uniform lighting throughout the illuminated space in accordance with AS1680. Where higher local illuminance levels are required for specific tasks, provide suitable local task lighting or provide suspended luminaires over the task.

Light Switches

In general, arrange local switching to each room. Locate light switches on the jamb side of the main entry door to the relevant room.

Where a large room such as a library has two or more entry points, provide multi-gang two-way and intermediate switching at all doors to suit the specific configuration of the space.

Arrange switching or daylight sensors to provide separate control of perimeter luminaires close to windows (as a rule of thumb, to a depth of twice the height of the windows); dimming of these in response to daylighting is preferred to switching.

The size, type and location of lighting controls which are normally used by occupants (except maintenance personnel), even if infrequently, should accord with the requirements of the Building Code of Australia, particularly Section J.

Access/Security Lighting

Internal security lighting shall be provided in the form of unswitched or after-hours automatically switched luminaires. Luminaires shall incorporate low energy (high efficiency) light sources and should be located at building entries, changes of direction to external pathways, and stairs in corridors.

Security and after-hours access lighting should consist of high-efficiency light sources. LED or metal halide should be used for general flood lighting. T5 fluorescent lamps or LED luminaires are appropriate for perimeter and access lighting. These should be controlled by a daylight (photoelectric) sensor in conjunction with a time clock.

Emergency and Exit Lighting

Emergency and exit lighting shall be provided as required under the Building Code of Australia and in accordance, generally, with AS 2293 Parts 1 and 2. Any alternative systems should be assessed for compliance by the relevant building surveyor in accordance with the Code. Systems shall consist of single point type luminaires, and generally employ:

► 2 watt LED self-contained non-maintained mode emergency recessed type;



► 2 watt LED self-contained non-maintained mode emergency surface-mounted type; and

► 3 watt or 4 watt LED self-contained maintained exit signs (Running Man legend).

Older light sources such as halogen may only be used where LED versions are not available (for example, in frog-eye gymnasium emergency luminaires).

Test Push Buttons or a Central Testing System shall be provided for testing the emergency and exit lighting in accordance with AS/NZS 2293.2. (Generally, the latter system would be applied to larger secondary colleges).

Lighting Switches

Lighting switches shall generally be of the polycarbonate rocker type, flush mounted where practicable, and adjacent to the closing side of doors.

In plant-rooms, switches shall be of an industrial type rated to IP56.

Flush-mounted switches on columns and walls shall be mounted in standard-size metal wall boxes to suit wall construction. PVC wall boxes may be used for PVC conduits but only where permitted.

Lighting switches shall be suitably rated to carry the switched load, with a minimum of 16 amp for fluorescent loads.

Where multiple switches are provided, they should be clearly labelled as to the lights they serve. Alternatively, a plan indicating which lights are controlled by which switches should be placed next to the switch panel.

Controls

Lighting controls should be provided to ensure that lighting is only on when required – that is, when the space is occupied, and little or no daylighting is present.

The following table recommends lighting control systems for applications.



Space Type Usage Pattern Conditions Recommended Control

Classroom Usually occupied

Multiple tasks like overhead projectors, whiteboard or blackboard, reading, class demonstrations

Refer also Section 8.7.2 – Security and Access Lighting and the Department’s Emergency & Security Management website: https://edugate.eduweb.vic.gov.au/Services/Schools/Infrastructure/Emergency/Pages/default.aspx. (Note that this site requires an Edumail user ID and password for access.)

7.11 Special Services

All electrical services work shall be undertaken in accordance with AS/NZS 3000 and relevant power authority.

7.11.1 Fume Cupboards

The construction, siting, installation, maintenance and use of fume cupboards is detailed in Australian Standard AS/NZS 2243.1. Section 4.4 states that “operations which may produce flammable or toxic vapours should be carried out either in a fume cupboard or, if this is not possible, they should be provided with local exhaust ventilation.”

Technology Areas and Hazard Levels

Depending on the courses offered by a school, there will be differing hazards associated with the likes of automotive engine testing, moulding plastics, etc. Schools must indicate to the consultant in their educational specification the courses they intend to offer and how they want to operate them so that a risk assessment can be undertaken and requirements determined.

Exhaust ventilation fans should be considered a minimum requirement for fume cupboards.Science Areas and Recommended Provision

It is recommended that each preparation room have a fume cupboard (preferably single-sided) and that one also be made available to senior chemistry classes. Fume cupboards are usually not required in physics areas but they might need to be considered in biology and agricultural science (again, generally for senior classes, and depending on the chemicals used and experiments conducted).

Construction

Construction materials should be selected to provide suitable resistance against chemicals handled. Generally a PVC shell with a chemical resistant one-piece laminated work surface is suitable for most demonstration applications. Sliding sashes shall be toughened glass or clear acrylic and feature adequate corrosion resistant counter weights. Sashes shall remain in place whenever stopped with a fixed minimum opening of 50mm.

Services

The following minimum services integral to fume cupboard construction should be provided:

► Power one double general purpose outlet (GPO) located either at the external top or side of the chamber but not within the chamber;





► Lighting one separately switched fluorescent luminaire (flame proof and corrosion proof) to provide 400 lux at the base;

► Sink one 200mm diameter, 150mm deep conical cup sink;

► Water one gooseneck style cold water supply outlet over sink; and

► Waste an acid neutralising tank into which waste can be discharged.

Controls

The following features should be provided:

► separate fan and light controls;

► separate controls for water and gas services external to the chamber;

► labelled emergency isolation switches for electricity and gas; and

► automatic isolation of electricity and gas in the event of inadequate air flow.

Performance

Select a fan and volume control system to maintain the required face velocity through an open sash area. The face velocity across the fully opened sash must measure 0.5 metres per second, and air exhausted through a fume cupboard must not be re-circulated to other rooms. The fume discharge point must be three metres above the roof. The noise level of the fan (as measured at the operator’s level) should not exceed 62dB(A).

Commissioning tests (as indicated in AS/NZS 2243.8) must be performed by the supplier upon installation and the results reported to the school.

There must be an adequate supply of replacement air to compensate for the volume exhausted. Centrifugal fans should be considered as a first choice in this operation.

Siting

The Australian Standard includes diagrams which indicate the distance fume cupboards should be from doors, walls, bench tops, etc. to minimise air flow disturbances.

7.11.2 Compressed Air

Compressors

Consider air-cooled rotary-scroll and rotary-screw oil-free compressor types. Compressors shall be driven by TEFC (totally enclosed fan-cooled) squirrel cage induction motors rated to IP54. Ensure that adequate acoustic control measures are provided to maintain acceptable noise levels.

Receivers

Compressed air receivers should be provided in accordance with AS 1210, sized to maintain the number of compressor start/stop cycles within the manufacturer’s limits, and be completed with the following:



► inspection opening;

► dial type pressure gauge;

► valved drain point and automatic condensate drain; and

► pressure relief valve.

Filters

Determine the level of filtration required to suit each application. Provide, in every case, a minimum filtration system comprising a woven media material capable of removing water droplets and particulate material to 1.0 m. Ensure that separated liquids are automatically drained away from filter material. Each filter shall be completed with an integral pressure differential gauge assembly showing required replacement times.

Pipe Work

Permanent pipe work is to be “Type B” copper tube to AS 1432, excepting suitable flexible connections to the compressor unit. All joints are to be brazed where practical, and continuous pipe lengths should be maximised. All pipe work is to be concealed from view in normally occupied areas. Protection from mechanical damage, where exposed, is also to be provided. Install automatic condensate drains to the mains pipe work. Grade mains at 1:100 to drain points. All branches shall be taken from the top of the main pipe work, and all pipe work shall be sized to ensure that pressure loss does not exceed 10% of the design supply pressure.

Valves

Provide globe type valves for isolation and throttling purposes, and plate check type valves for non-return applications. All valves shall be connected by flange or union. 7.11.3 Reticulated Gas Services

Scope

The provision of reticulated bottled gas systems for specialist applications excludes LPG and vacuum systems.

Standards

Non Flammable Gases: AS 2896

Oxygen and Acetylene: AS 4289 – 1995

Storage Facilities: Dangerous Goods (Storage and Handling) Regulations Statutory Rule No. 323/1989

Enclosures

Determine suitable locations for permanent storage of cylinders with regards to safe storage and handling procedures, security of plant and equipment, and capital costs. Preference should be given to external storage locations. Within each storage area, all cylinders (whether “on-line”, “on-standby” or “spare”) shall be securely restrained in an upright position. All cylinders for “portable”



use shall be secured to stable, wheeled trolleys. Ensure an adequate separation of Class 2.1 and Class 2.2 materials.

Pipe Work

Copper pipe work is generally acceptable for most services except acetylene where stainless steel shall be used. Pipe work should be sized for a pressure loss not exceeding 5% of the reticulated supply pressure.

7.11.4 Dust Extraction System

Dust Extractors

Units shall be self-contained mechanical cleaned type, located with regard to acoustic performance, equipment security and serviceability. Each unit shall feature:

► statically and dynamically balanced centrifugal mild steel fan, direct driven by a 415V, 3-phase TEFC (totally enclosed fan-cooled) motor rated to a minimum of IP54 (maximum fan speed 1440 rpm);

► woven fabric media with abrasive resistant properties, selected for optional performance with regard to operating cost, collection efficiency and service life;

► acoustic attenuation of the fan assembly and discharge ductwork where necessary (noise levels within occupied areas and externally should be made acceptable);

► electrical driven shaker assembly to clean filter media;

► bin type dust collector with robust sealing assembly; and

► explosion relief vent with minimal ductwork and changes in direction to a safe discharge area.

Ductwork

All ductwork shall be of circular type galvanised steel, suitable for “high pressure” application in accordance with “HVAC Duct Construction Standards – Metal and Flexible” published by SMACNA Incorporated (USA), and feature:

► sizing for transport velocities not less than 18 metres per second;

► radiused bends and angled take-offs to main ductwork;

► steel flange type bolt clamps on joints enabling easy removal for clean out;

► “clean out” access panels, where required, and removable caps at end of duct runs; and

► blast gate dampers where required for balancing purposes.

7.11.5 Lightning Protection

A risk assessment will be carried out in accordance with AS/NZS 1768. A risk index of greater than or equal to 12 shall require the implementation a lightning protection system. 7.12 Centralised Energy Systems



Centralised energy systems should be avoided. Satellite boilers and smaller packaged airconditioning plants provide greater flexibility, control and energy savings.

Effective temperature and time-clock controls should be provided to all centralised boilers and packaged plant. Complex building automation (energy) systems should be avoided.

Refer Section 7.6 – Heating, Section 7.7 – Ventilation and Section 7.8 – Cooling.

7.13 Storage

Well-designed storage provides the space in which to keep essential articles and equipment. It must also facilitate their efficient use and handling.

The provision of storage can represent a significant cost to the design and development of a school, both in terms of accommodation and ease of access. School Construction Rates currently allow for locker areas and site stores to be considered at a part-internal and part-external average rate of $900/sqm.

The different abilities of anticipated users must be kept in mind when installing new storage or re-assessing existing storage facilities. In addition to adult users, students may also have access to stored items. AS 1428.2 and AS 1428.3 provide guidance. Safety and convenience are paramount.

Consider the following factors:

► make storage access as convenient as possible (relevant storage spaces should be directly accessible from activity spaces);

► locate bulk storage so as to be convenient for the receipt of deliveries;

► protect articles from breakage, moisture, heat, cold, misuse, theft, etc.;

► control distribution or use;

► provide a safe location for dangerous items; and

► share storage between spaces to enable the creation of larger, more useful spaces.

When designing storage areas, the Occupational Health and Safety Regulations 2007 S.R No. 54/2007, including provisions of the Manual Handling and Prevention of Falls Regulations, must be taken into consideration. This is particularly important in designing archive storage areas where preference should be given to small-sized archive boxes.

Section 8:External Services

Boronia K-12 College Architect: Minx Architecture Pty Ltd

138

Department of Education and TrainingSection 8 - External Services

8. EXTERNAL SERVICES

8.1 Introduction

When designing any given service, the designer is required to make use of the most cost effective materials and installation techniques available, commensurate with appropriate levels of service and durability, and in accordance with the philosophy outlined in this Handbook.


Where classes, types, etc. are referred to, they are in accordance with the relevant Australian Standard. All dimensions are in millimetres unless noted otherwise.

8.2 External Stormwater Drainage

8.2.1 General

A drainage system shall be provided to drain the site. All drainage in the region of buildings and paved areas shall be by combination of open inverts, kerb and channel, and underground drains as appropriate. Surface drainage in grassed areas may be collected by swale drains.

Design of the drainage system shall be based on design methods outlined in Australian Rainfall and Runoff, and the relevant authority’s requirements.

Where the site layout and falls provide an acceptable means of overland flood relief, the Average Recurrence Interval (ARI) adopted for design shall be not less than 5 years. In other cases the ARI shall be not less than 50 years.

The legal point(s) of discharge shall be obtained from the relevant authority.

8.2.2 Rainwater Collection

Consideration should be given to the retention of stormwater on site through the use of tanks. This water can be used as an alternate source for the irrigation needs of the school. (The cost of this installation is now included in the school rates and is no longer a special factor.) Consideration must be given to the following when determining the suitability of rainwater tanks:

► the purpose of the rainwater tank – whether for irrigation or connection to specific fixtures such as toilet cisterns (or both);

► the location which best maximises the catchment area;

► the estimated roof catchment yield;

► security issues; and

► maintenance issues.

Building Quality Standards Handbook May 2016 139


In accordance with AS/NZS 3500 Part 1.2 Water Supply – Acceptable Solutions, water collected and stored in rainwater tanks and used as an alternated water supply must not be used for human consumption.

In addition to complying with all relevant standards, installations should comply with the Standards Australia Handbook HB 230, Rainwater Tank Design and Installation Handbook. This document provides practical information for the collection, storage and use of rainwater. Although it is aimed at urban environments and private residences, the information is relevant to school use. It also provides a means of calculation of anticipated water harvesting yields.

Bladder-type tanks

Bladder type tanks are recommended for use beneath floors, decks, etc. However, they should be located in a position where they are accessible for maintenance.

8.2.3 Pipe Work and Structures

All pipework and structures should conform to Water Services Association of Australia Water Code WSA 03.

Pipe sizes shall be not less than:

► DN (nominal diameter) 100 for connection direct to down pipes;

► DN150 downstream of any grated pit; and

► DN225 downstream of any side entry pit.

Pipe work materials shall be:

► for DN100 and DN150, solvent-jointed UPVC conforming with AS/NZS 1260;

► for DN225 and greater on straight runs without junction fittings, rubber ring jointed reinforced concrete conforming with AS/NZS 4058 or rubber ring-jointed fibre reinforced cement pipes conforming with AS 4139, of the appropriate class; and

► for DN225 and DN300 straight runs with junction fittings, solvent-jointed PVC conforming with AS/NZS 1260 or rubber ring-jointed fibre reinforced cement conforming with AS 4139, of the appropriate class.

Junctions of pipes DN300 or smaller shall be made either with oblique or sweep-junction proprietary fittings, or at pits.

Junctions of DN100 or DN150 pipes with DN375 or larger pipes may be made with saddle-type fittings.

Junctions of pipes DN225 or larger with DN375 or larger pipes shall be made at pits.


Post-occupancy evaluations have reported leaking underground bladders that cannot be accessed for repairs.

140


Pit covers shall be of a tight fitting bolted-down design or have sufficient weight to prevent their easy removal.

All pit construction should conform to the relevant authority standard.

Downpipe Filters

.

8.2.4 Stormwater Drainage Issues

The design of the drainage system shall address the following issues as appropriate:

► on site retention;

► erosion control;

► litter control;

► sedimentation control; and

► maintenance.

Drainage Problems

8.3 External Sewer Drainage

8.3.1 Pipe Work and Structures

The preferred pipe work material is uPVC except where discharge or other conditions require an alternative material. All pipe work and structures should conform to Water Services Association of Australia Sewerage Code WSA 02.


Post-occupancy evaluations have reported the use of unsatisfactory downpipe filters which block in heavy rain. “Leafeater” type screened downpipe rainheads are one recommended option. Here the upper section of the downpipe discharges onto an angled mesh surface across a “rainhead” attached to the lower part of the pipe. Leaves are screened by the mesh and fall clear because of the angle, allowing water to pass through the mesh and into the “rainhead”. These devices are normally located just below the eaves.

An alternative strategy that has been successfully use in schools entails stopping downpipes short of ground-level and catching the discharge in grated pits

Recent post-occupancy evaluations have found a number of schools with inadequate stormwater drainage, resulting in flooding and unsatisfactory site conditions. Drainage seems to have been paid little priority.

Grated stormwater pits were set too high above adjacent ground level, and drainpipes under floors leaked, creating smells and damage to the structure.

141


Sewer inspection chambers shall be provided to facilitate maintenance, and be located at junctions of major sewer drainage runs and at not more than 60 metre intervals.

Additional overflow relief gullies shall be provided to maximise the protection of buildings against blocked sewers.

8.3.2 Sewer Design Issues

The design of the sewer drainage system shall address the following issues as appropriate:

► grease arrestors;

► neutralisers;

► solvent/oil interception;

► acid drains;

► trade wastes; and

► maintenance.

8.4 External Water Supply

The supply of water is governed by the relevant Australian Standard as well as regulations and by-laws exercised through local water authorities. (Victoria’s Safe Drinking Water Act 2003 (refer Department of Human Services) deals specifically with the regulation and quality of drinking water supplies.)


Pipe work, valves and fittings shall comply with AS/NZS 3500.3, with the additional requirement that all pipe work below buildings and concealed in buildings shall be copper tube “Type B” in accordance with AS/NZS 4058.

The preferred pipe work materials are:

► for DN32 and greater, UPVC except for the limitation above and the limitations of AS/NZS 3500.1; and

► for DN25 and smaller, copper tube “Type B” in accordance with AS/NZS 4058.

8.4.2 Backflow Prevention

Provide all backflow prevention devices as required by the relevant authority and AS/NZS 3500.3.



8.4.3 Irrigation Systems

Provide irrigation systems as appropriate to garden and grassed areas. Refer Section 10.5.2 – Irrigation Systems.

8.4.4 Other External Supply Issues

The design of the external water supply system shall address the following issues:

► enclosure of equipment to prevent vandalism; and

► dual supply to site where practical.

8.5 External Gas

8.5.1 Natural Gas Meters

Meter enclosures shall be well secured. Meter by-pass pipe work facilities should also be provided.

8.5.2 LP Gas Storage

Size bulk storage tanks and cylinders with regard to the maximum required vaporisation rate, practical delivery intervals and cost. Carefully locate bulk storage tanks and cylinders with regard to statutory requirements, physical security, and ease of refilling or replacement.

Provide external tanks with 75mm thick concrete plinths extending 500mm beyond the tank enclosure and with an 1800mm high chain mesh enclosure and lockable access gates. Tank finish shall include abrasive cleaning, prime painting and top coating. A lockable, corrosion protected sheet metal enclosure with concrete base should also be provided for external cylinders.

8.5.3 Pipe Work – Below Ground

All consumer pipe work shall be “Type B” copper tube to AS 1432. All joints are to be brazed where practical. Pipe work installed in the ground shall be complete with a corrosion resistant external wrapping. Ensure an adequate separation distance from other in-ground services, structures and earthing electrodes. Do not install pipe work within concrete slabs and avoid installing pipe work under buildings where possible. Size pipe work to limit pressure loss to mandatory limits, and include a 10% safety factor. Where LPG is likely to be replaced by natural gas within five years, allow for natural gas in the pipe work design.

8.5.4 Gas Booster

Gas pressure booster devices are to be avoided where possible. Where required, locate them carefully and ensure that adequate acoustic measures are provided to meet acceptable ambient and internal noise criteria.



8.6 External Fire Protection

8.6.1 General

Provide a hydrant system to satisfy the minimum requirements of the Building Code of Australia, AS 2419 and local fire authority.

8.6.2 Fire Hydrants

Preferred hydrant installations are external dual-head individually-controlled outlets, with access and hard standing for a fire appliance to connect to the hydrant. Maximum hose length should not exceed 20 metres. Hydrant fixtures and installation should conform to Water Services Association Water Code WSA 03 and AS 2419.1. Internal hydrants are not preferred.


Pipe work, valves and fittings shall comply with AS 2419.1.

The preferred pipe work material is uPVC except for the limitations on use imposed by AS 2419.1.

8.6.4 Other Issues

The design of the external fire protection system shall address the following issues:

► fire brigade booster connection;

► booster pumps;

► source of water supply if street mains supply is inadequate or not available;

► hose couplings compatible with relevant fire brigade;

► use of street hydrants to minimise the number of on site hydrants;

► appropriate valving for hydrants and hose reels; and

► signage and notices.

8.7 External Electric Light and Power

8.7.1 External Power

All general power outlets provided externally shall be of the following type:

► surface mounted;

► weather resistant with IP56 protection rating;

► have rotating switch mechanism;



► feature an integral 3-pin with flat earth single phase socket or 5-round pin three phase socket;

► include spring loaded flap;

► screw neck to plug base; and

► feature keyed switch mechanism, if necessary.

Sub-circuit cabling should be installed to outlets either internally concealed within the building structure or within rigid non-metallic or metallic conduit. Non-metallic conduit subject to UV radiation should be suitably treated to prevent degradation.

8.7.2 Security and Access Lighting

Security lighting to carparks, pathways and the perimeter of all buildings should be provided to ensure safe access. Consider also the needs and applications associated with out-of-hours tuition, community hiring of facilities, and vandalism.

All external lighting for security and access shall be in accordance with AS1158.3.1.

Consider post-top mounted luminaires equipped with either metal halide lamps with electronic gear or LED light sources for energy efficiency. Locate luminaires at 3.5 metres above ground or higher to avoid vandalism.Useful security hints and practical advice can be obtained from the Department’s Security Services website https://edugate.eduweb.vic.gov.au/Services/Schools/Infrastructure/Emergency/Pages/default.aspx. (Note that this site requires an Edumail user ID and password for access.)

Controls

Lighting shall, in general, be controlled by a photoelectric cell in conjunction with a time controller.

Motion detectors may be used to activate security and access lighting provided that consideration is given to avoidance of nuisance activation, i.e. a narrow detection field may be better than a wide field.

Motion detector switching is not appropriate for any lighting that has start-up and restrike periods (i.e. high intensity discharge lamps).

Light Sources

Security and after-hours access lighting should consist of high-efficiency light sources. LED or metal halide should be used for general flood lighting. T5 fluorescent lamps or LED luminaires are appropriate for perimeter and access lighting. These should be controlled by a daylight (photoelectric) sensor in conjunction with a time clock.





Luminaires

Luminaires should be vandal-resistant and of a minimum IP65 rating, and have a power factor corrected to 0.85 lagging or better, with superimposed pulse igniter circuits where igniters are required.

8.7.3 Underground Services

Underground cable conduits should be supplied and installed for the enclosure of HV and LV cables. Cable conduits for HV and LV cables shall be laid at 750mm and 500mm (to top of conduits) below finished surface levels respectively.

Where cabling is subject to mechanical damage or is installed with less cover than specified above, metallic protection to cabling must be provided.

9. COMMUNICATION SERVICES

9.1 Introduction

The Department is one of the largest users of IT in Australia and among worldwide leaders in the use and implementation of information and communication technologies (ICT). The State school system consists of over 1700 sites which are connected to a WAN (Wide Area Network), and each has its own LAN (Local Area Network). Furthermore, every school receives high-capacity broadband internet through the Government’s initiative, VicSmart.

ICT standardisation is used to allow the Department to provide support and management of ICT services across both the shared WAN and local school LAN’s.

The Department’s Information Technology Division has produced guidelines on the design and installation of ICT in schools to support ICT standardisation. These guidelines follow appropriate infrastructure and industry standards. These include:

► ICT Design Models for Schools (Standards – Best Practice Guide); and

► ICT Design for Learning Spaces (Patterns – Application of standards, with examples from “Building the Education Revolution”).

The ICT Design Models for Schools must be studied before a new school is designed or an existing school embarks upon updating its ICT capabilities. This document provides more information on all aspects of an ICT installation and goes into greater detail than this handbook. In overall terms, it:

Introduces issues that affect the design of ICT installations; Discusses:

o Infrastructure and Connectivity;o ICT devices;o Peripherals and Innovation;o Professional Learning and Support

ICT may also require customisation to suit the needs of local school students, staff and visitors of varying abilities.

In a project, the main sub-consultant involved with ICT will be the communications engineer. This consultant may be able to advise further on ICT matters or may require a specialist in communication design. In any case, the school is advised to obtain advice on their ICT requirements.

The consultant must ensure that the ICT design complies with the Department’s best practice ICT Design Models for Schools. The consultant should discuss the ICT proposal with the school/Department representative, and implement any school requests where practical. Consultation is to continue throughout the project, including discussion on the introduction of new technologies that may have developed during the planning period.



In general, communication services in schools cover data (administrative, curriculum, etc), emergency warning systems, video (including audio-visual), voice (telephone), library automation, public address, TV antenna (including satellite dish), and security. Multi-campus sites are now required to be linked for communication services.

Wireless technologies have been installed at every school since 2004 and are required to be installed in new buildings in accordance with the standards outlined in the ICT Design Models for Schools. Wireless technology in schools has grown rapidly to a fleet of over 32,000 WAPs, supporting mobile access for over 500,000 devices. This included the deployment of eduSTAR.net, an enterprise-class wireless network to provide students and teachers with mobile access to technology.

Schools across Victoria are integrating ICT into their curriculum in ways that enhance student computer literacy, share knowledge and information.

► ICT Procurement (via the whole of Department contract procurement arrangement)http://www.education.vic.gov.au/school/principals/infrastructure/Pages/ictproducts.aspx https://www.edustar.vic.edu.au/catalogue/Pages/HardwareHome.aspx

9.1.2 National Broadband Network (NBN)

The NBN is being ‘rolled out’ throughout the country and will come on line gradually. When it is available to an address, the land owner will be notified and a date set for when the existing network will be switched off. Since all Victorian government schools are provided with fibre-to-the-premises by Telstra through VicSmart, NBN will not impact the ICT component of schools.

It is possible to check if there is NBN in the relevant area at nbnco.com.au or via a Google search for the appropriate site. The telephone enquiry number is 1800 687 626.

The landowner (DET on behalf of the State of Victoria) will arrange with NBN to maintain telephone and internet services. DET will arrange this with a Whole of Victorian Government (WOVG) service provider. Application to connect to the NBN will be dealt with by the school’s consultant.

9.2 Infrastructure

9.2.1 Cabling Design and Infrastructure

Information and Communications Technology (ICT) requires cabling to deliver electronic capabilities for existing and future technologies.


https://www.edustar.vic.edu.au/catalogue/Pages/HardwareHome.aspx

http://www.education.vic.gov.au/school/principals/infrastructure/Pages/ictproducts.aspx

http://www.education.vic.gov.au/school/teachers/support/Pages/elearnresources.aspx

http://www.education.vic.gov.au/school/teachers/support/Pages/tecsupport.aspx


Lead-in cabling, cable trenching and distribution frames are clearly explained in Telstra guidelines that are available from the Optus help desk (tel. 1300 659 749).

Professional data cabling consultants should be engaged (as sub-consultants to the communications consultant) to design and document the requirements of the school.

Some key considerations of cabling design are: Cable type and quantity: will determine how much e-learning can be implemented and the

economies available; Design of the cabling infrastructure: will determine user flexibility and amount of change

that is available over the life of the cabling (typically 10+ years); The quality of the installation will determine the performance able to be achieved; The continued increase in wireless devices and Internet use.

In addition, consideration should be given to desirability and practicality of the extent of cabling infrastructure installed to enable an ‘intelligent building’; the integration of data, voice video, security audio visual, building automation (for building services and access control), etc, over Internet protocol (IP).

9.2.1.1 Cabling Design Elements

Cabling Design will follow the requirements of each individual school size and growth potential. Key considerations are:

Provision of growth space in a communications room must be large enough to be future-proof;

Choice of cable (category) should cater for future expansion. The Department recommends all copper cabling, connectors, patch panels and patch cords are minimum Class Ea (Category 6A) standard;

Cable distribution cabinets must be sized to allow for future expansion; Copper cable runs (possibly utilised for telecommunications) have maximum lengths

between panels and outlets; Optical fibre is required between buildings. The Department recommends minimum OM3

grade, multimode outdoor rated cable; Optical fibre is required within buildings where copper distance limitations are not met or

communications devices require fibre connections. For these purposes the Department recommends minimum OM3 grade, multimode cable;

Cables must not be overly bent requiring the design of suitable cable pathways within a building.

It is essential to note that all the cabling for the ICT Infrastructure must support the School administration and learning objectives. Therefore the installation must be of the highest standard and covered by the appropriate compliance certificate and minimum of 25 years warranty.



9.2.1.2 Number of Network Points Required

Cabled power and data points should provide the flexibility to adopt to a range of learning space designs. Thus a combination of floor boxes, ceiling mounts, wall points and wireless access is recommended.

Learning Space Capacity: 25 students and 1 staff member

Optimal number of data points

Usage

6*Specialised Student use.For example and subject to the shape of the room. Considerations: Is the learning space the row, street, bank or integrated spaces for computers

2 Wireless access points (WAP) on ceiling central to the room. 1.5 WAP’s per learning space may suffice. E.g. 3 WAP’s shared between 2 learning spaces

1 Network data projector on ceiling at each data projector location

1 Telephone placed at a convenient area for staff and/or student use based on school policy

1 Staff use (0.5-2 metres left or right from interactive whiteboard)

* Depending on a number of factors including the learning space design, student wireless devices and access to fixed wired devices, a school may feel it is necessary to increase (or decrease) the number of data points for students per learning space.

9.2.2 eduSTAR.net Wireless Connectivity

The eduSTAR.net enterprise wireless network provides key wireless infrastructure to support the growing use of mobile devices in Victorian education.

The eduSTAR.net Enterprise Wireless Network is accessible to: School educators, administrators and leadership 24 hours x 7 days per week. School learners (students) have access to the service 6 am and 8 pm, weekdays.

School wireless networks (WLAN) add flexibility and mobility to staff and students throughout the school.

The benefits of installing a WLAN in a school include: Staff/Students can effectively use laptops and mobile devices collaboratively in open spaces. Installing a WLAN requires less physical work than installing or adding to a LAN. WLANs can expand in size and functionality; access points can be added and be upgraded.

WLANs can start off small and grow in size and complexity as needed. WLANs allow users to move freely around the room, to wherever access points are in

operation.



The use of wireless devices is and will be ever increasing. However, wireless communications does not replace a cabled system; it complements and adds flexibility. Wireless access points (WAPs) need power – to be plugged-in – and a connection to the building’s data network.

It is signal strength that determines the speed and reliability of wireless network access so good coverage is essential to a successful system. Information on WAP mounting, wireless best practices and safety can be found at the following link:Wireless Access Point Mounting, Best Practices and Safety

The recommended Wireless Access Point for extending school wireless environments is the Cisco 3700 series. These can be purchased via the Department’s eduSTAR catalogue.

Although it is suggested above that 1.5 WAP’s are suitable for 25 students, this is very much an average and depends on:

How many devices are in use at the same time? The Department recommends 1 WAP to 17 devices to support 1-to-1 device use in schools;

The quality and condition of the WAP; The construction materials of the school building.

As always, future growth requirements for wireless connectivity must be considered and any wireless expansion design must comply with the Department’s best practice ICT Design Models for Schools.

9.2.3 VicSmart Network

The Victorian school system consists of over 1700 sites which are connected to the VicSmart WAN (Wide Area Network), and each has its own LAN (Local Area Network).

VicSmart WAN connects schools to each other, central systems (business systems, learning systems) and to the internet via the shared service eduSTAR.ISP.

9.2.4 eduSTAR.ISP - Internet Service

The school internet service (eduSTAR.ISP) provides all schools with filtered access to the internet. This service is provided at no cost to schools.

The school internet service provides the following capabilities: Safe and filtered access to the internet; Hosting for school public websites; Email services; Management and administrative console.

Figure: VicSmart and eduSTAR.ISP Overview

9.2.5 Communication Room & Cabinets

The communication room should be in a central location for the school servers and switches that run the school network. It has heat-producing machines that require it to be air conditioned to avoid overheating. It is not a suitable location for a workplace. ICT staff should have a separate office with remote access to administer the servers and switches. The room needs to be carefully designed to allow for easy access to the rear and front of machines. The communications room should be a dedicated room for ICT and associated equipment only. Designed growth space should be a minimum of 40% of the original installation. The room should be secure and lockable and be equipped with suitable air conditioning to cater for future growth.

9.3 Communication Services

In general, communication services in schools cover the following and will be installed complete in new schools:

Data; Voice (telephony); including VoIP (Voice over Internet Protocol), if desired; Security.

In existing schools, it is necessary to work with the existing systems so that major alterations are not required, except in extraordinary situations.

Any new development involving communications must be registered with Telstra via the following link to the Telstra Smart Community website: http://www.telstra.com.au/smart-community/?red=/smartcommunity/.


http://www.telstra.com.au/smart-community/?red=/smartcommunity/

http://www.telstra.com.au/smart-community/?red=/smartcommunity/


9.3.1 Data

Data is the primary element that is transported around by cables in an ICT network. The form it is used for is determined by the end device function, e.g. telephones mean voice, wireless access point means a wireless signal, a wall data point is where a desktop can be plugged in. In essence, anything to do with information sharing can use the data infrastructure. For example:

Student and Staff Internet and WAN access; Video-conferencing; Unified communications (voice/video/messaging), e.g. Skype and Lync; CCTV and IP video surveillance; Audio visual throughout the school; Public address & emergency warning (see 9.6); Clock-bell services (see 9.7); Interactive whiteboards and panels; Library automation; Building car park access control; Printers and copiers; TV antenna (see 9.5).

Along with the flexibility of information sharing capabilities, cyber safety of those involved must be considered.

9.3.2 Voice (Telephones)

A traditional system comprises copper wiring from Telstra. Older type wiring is known as PSDN and is usually installed as a 3 pair service (this allows for 3 separate services to run off the wiring e.g. a phone line, a data line and a fax. The phone lines terminate in the school at a PABX that allows a call to be directed to a particular receiver. Newer types of supply are called ISDN and are made of optical fibre which increases the capacity dramatically, with a choice of 10, 20 or 30 pairs and the distribution is also via the PABX. ISDN is also able to support VoIP (Voice over Internet Protocol) where the voice cables are actually the same as data cables and can perform either function.

VoIP is a method whereby voice is distributed throughout the school via the Internet Protocol (IP) using school data cabling and switching infrastructure. This allows telephones to be connected to the phone system via any data point (subject to functional limits). It is therefore a much more flexible method of distribution. Change management is simpler as a standard IT technician is able to make changes rather than require a qualified telephone engineer. On the down side, the VoIP phones are considerably more expensive and a local IPBX (IP Call Manager) is required to translate IP voice traffic to a PABX gateway for external calls. The VicSmart WAN does not support VoIP traffic.

9.3.3 Security (Intruder Detection System)An intruder alarm system which is to be monitored by the Department’s Security Services Unit (SSU) shall be designed and installed in strict accordance with SSU guidelines using only SSU approved contractors.

Advice and copies of the guidelines which are contained in the ‘Alarm System Installation & Maintenance Specification’ along with a list of approved contractors is available by contacting:

► Infrastructure to support security systems such as intruder detection systems. The installation of security systems must be included within this budget.

The Victorian School Building Authority has access to an ICT Cost Calculator to assist with costing all ICT equipment covered in sections 9.1 to 9.4.

9.5 Television Distribution System

A system suitable for the reception and distribution of free-to-air (FTA) television should be considered for new schools. The designer should seek confirmation with the school or Department representative regarding the areas requiring television points.

9.6 Public Address System

A public address system shall be installed as “an inbuilt communication system used only for emergency warnings purposes”, as defined in the Functional Statements, item DP9 (b), of the Building Code of Australia.

Public address (PA) cabling is specific for this particular system.

The PA system comprises a public address amplifier and speakers. Cabling design is specific to this type of system.

The public address amplifier shall feature:

250 watt amplifier minimum;

3 balanced microphone inputs;

2 auxiliary inputs;

radio microphone.


https://edugate.eduweb.vic.gov.au/Services/Schools/Infrastructure/Pages/default.aspx


9.7 Clock-Bell Services

The provision of stand-alone clocks in schools is preferred, so no infrastructure is needed for this service.

Bell services can be achieved by the public address service. Again, no separate infrastructure will be needed if a public address service is selected.

9.8 As-built Documentation

Hard and soft copies of as-built documentation must be submitted in accordance with Section 8.2 of the Standard Specification for Information Technology and Telecommunications Cabling.

9.9 Hearing Augmentation

9.9.1 Accessible Buildings Program

The Department provides hearing augmentation systems on application only, through the Accessible Buildings Program, to enable students, parents and teachers with hearing impairment to access mainstream schools.

9.9.2 Hearing Augmentation in Existing School Buildings

In accordance with the requirements of the Disability Discrimination Act 1992, the Disability (Access to Premises – Buildings) Standards 2010 and the Building Code of Australia, the following is a complying proposal for hearing augmentation in Class 9b (school) Buildings.

Following application by the school through the Accessible Buildings Program, the Department will provide a hearing augmentation system that caters for the needs of the hearing impaired student. The solution may vary depending on the particular need of the student and the type of personal hearing device the student is using.



Hearing augmentation systems shall be entirely distinct from the public address system (see 9.9 Public Address System). The Department will provide Building Surveyors written confirmation of the function of inbuilt communication systems to allow for the certification of construction documents and issuing of building permits.

9.9.3 Hearing Augmentation for Capital Works Projects

New school projects, and refurbishment projects where applicable, must install a Wireless FM Transmitted hearing augmentation system in areas likely to be utilised for community use, including:

Gymnasiums

Section 10:Site Works & School Landscaping

160

Department of Education and TrainingSection 10 – Site Works & School Landscaping

10. SITE WORKS & SCHOOL LANDSCAPING

10.1 Introduction

A well maintained, functional and aesthetic school site has a positive influence on student values, behaviour and performance.

All aspects of site development, including landscaping, should be reflected in a school’s masterplan. Landscaping should not be dealt with in isolation but form an integral part of the overall development.

Every effort should be made to retain existing trees of use and importance. To achieve this, a proper survey should be carried out of all significant trees and site features prior to any masterplanning.

The development of school grounds should be focused to satisfy goals in these major areas:

► provision of a safe, manageable, pleasant and ecologically responsible outdoor environment;

► provision of areas and facilities which meet outdoor curriculum requirements;

► provision of areas and facilities which meet outdoor play, assembly and physical education requirements; and

► consideration of ecologically sustainable design (ESD) performance related to landscape irrigation and water efficiency, transport design, cyclist facilities, and recycling storage areas.

It is important that school grounds are developed to meet these goals in a balanced and comprehensive manner.

In the context of school facilities provision, site development comprises five distinct categories:

► roads, footpaths and hard courts;

► fencing;

► planted landscaped areas;

► covered ways; and

► site improvements.

The extent of site development will vary and the needs and priorities of new and existing schools will clearly differ. For example, a new school project usually requires more site development than a major facilities upgrade at an existing school.

During the design phase of the buildings and site, it is the responsibility of the principal consultant to ensure that careful consideration is given to specific site development requirements, bearing in mind the approved budget for this.

Post-occupancy evaluations (2005) noted that a lack of site investigation was found to have led to issues ranging from stormwater drainage problems (many of which remained unresolved), asbestos removal, rock removal and excavation, and fire service rectification.



Other important issues to be addressed during the planning of a site development scheme include:

► requirement for a complete site masterplan – incorporating, among other things, weather protection and shading – at a scale not less than 1:100 and on an accurate survey base (this is mandatory for new school projects, but may not be necessary for all facilities upgrade proposals);

► current and proposed school/community funded improvements;

► functional and safe access around the site for pedestrian and vehicular traffic (this should include traffic planning in relation to drop-off and pick-zones for students by cars and, where relevant, buses, with separation of pedestrian and vehicle traffic);

► provision of parking for teachers, parents, visitors and deliveries;

► emergency access;

► maintenance and security (the ongoing cost of site maintenance can be minimised by careful planning through all stages of design);

► direct routes to a full range of facilities (e.g. toilets, drinking fountains, canteen, hard court areas, etc.);

► provision of non-slip path surfaces;

► passive recreational area requirements;

► active recreational area requirements;

► planting to stop erosion, mark boundaries, provide shade and shelter, channel pedestrian traffic and provide visual screening (generally, planting should have regard to maintenance, aesthetic and educational values); and

► provision of disabled access throughout the site, including car parking in accordance with the Building Code of Australia.

All design, materials and construction shall comply with the Building Code of Australia and relevant Australian Standards.

In terms of environmentally preferred materials, contact Sustainability Victoria: http://www.ecorecycle.vic.gov.au/. (With respect to construction, demolition, refurbishment or landscaping, waste minimisation planning can lead to a reduction of site waste and a more intensive use of materials.)

Useful security hints and practical advice can also be obtained from the Department’s Security Services webpage:https://edugate.eduweb.vic.gov.au/Services/Schools/Infrastructure/Emergency/Pages/default.aspx. (Note that this site requires an Edumail user ID and password for access.)

Details relating to landscaping must be addressed in the Design Development report.



http://www.ecorecycle.vic.gov.au/


10.2 Roads, Footpaths and Hard courts

10.2.1 Vehicle Access Roads

Vehicle access roads provide functional and safe access onto the site. For safety reasons, they should be separate from pedestrian access paths. On-site staff parking should be designed with minimal site intrusion, and the extent of access roads should be minimised.

Consideration should be given to a single point of vehicle entry into each staff car parking area.

For economic reasons, delivery vehicle access is usually incorporated into the staff car park. Delivery vehicles will require access as close as possible to areas such as administration, canteen and technology. Direct access to these areas, however, is not mandatory and the trolleying of equipment and goods over short distances is acceptable.

Access roads are usually constructed of heavy duty asphalt (recycled concrete aggregate and asphalt may, where feasible, be specified) with associated kerb and channel. Speed traps, signage and bollards should be considered in the interests of safety.

Carriageway dimensions and alignments should satisfy the relevant road authority standards. Refer to the Vicroads website (http://www.vicroads.vic.gov.au/Home) for helpful information.

Consideration should also be given in the planning of site facilities to the access and circulation of emergency vehicles such as ambulances and fire trucks, as per the relevant Australian Standards and authority guidelines.

10.2.2 Parking Areas

There is no requirement for the Department to provide staff car parking. However, where site conditions permit (and subject to the availability of funds), provision will be made in accordance with the following long-term enrolments.

97-104 44 145-155 44105-112 46113-120 48

Considerations which may influence the location of staff car parks include:

► access for staff from car park to buildings; and

► access to physical education facilities (these can be shared with the community during after hours).

A minimum of one parking bay should be provided for the disabled as part of the entitlement as specified in the Building Code of Australia.

Provision of all parking – including dimensions and layout – shall conform with the Building Code of Australia.

Staff car parks should be constructed of heavy duty asphalt with kerb and channel, line-marking and kerb ramps that accord with the Building Code of Australia.

10.2.3 Provision of Bus Parking for Specialist and Special Development Schools

On-site bus parking facilities are provided to specialist and special development schools to allow for the alighting of students within school grounds.

Bus parking facilities, including turning circle allowances, must be designed for the range of bus sizes operated by schools, up to and including 57-seat school buses.

The following table lists the dimensions of a 57-seat school bus.



Overall Length 12250 mmOverall Width 2480 mmOverall Height 3580 mmWheelbase 6050 mmWheel Track Front 2108 mmWheel Track Rear 1854 mmMinimum Lift-off Clearance 200 mmApproach Angle (O) 8.3Departure Angle (O) 7.5Front Overhang 2720 mmRear Overhang 3480 mmMin. Turning Diameter 24000 mm

Access to drop-off areas must be suitable for people with disabilities, in accordance with current Australian Standards.

Consideration should be given to the provision of access equipment such as wheelchair lifts.

10.2.4 Waste Disposal

A waste disposal facility is usually incorporated adjacent to the car parking area and sited as close as possible to the street boundary. This is necessary for safety reasons and limiting the intrusion of pick-up trucks onto the site. The waste disposal bay should be constructed of high strength concrete. Suitable screening should be considered around the waste disposal facility.

Access to waste disposal bins should take into consideration:

► the provision of an adequate space for large vehicles to enter and manoeuvre; and

► a pavement design which is sufficient to support large vehicles and withstand the “tyre scrubbing” forces arising from vehicle manoeuvres.

Operational wastes are those generated once a facility is in use. These include food wastes, beverage containers, paper, cardboard and other packaging materials. Effective design should ensure that classrooms, staffrooms, canteens, libraries etc. have areas allocated where waste and recycling bins are placed. The waste disposal facility (from which waste and recyclables are collected) should be of a size to accommodate and store these materials prior to pick-up. The facility should also take into account the size of collection vehicles and methods of collection (e.g. lift mechanism, etc.).

The disposal facility should conform with AS 2890 in terms of size and vehicle movement requirements.



10.2.5 Pedestrian Paths

A path network is required to provide a safe, functional and direct means of access to and around school buildings. Access is required from the car park to buildings for staff, visitors and deliveries.

Such paths must also be suitable for people with disabilities in accordance with current Australian Standards. Access for people with disabilities is not required to every door of every building but, rather, to each separate functional area within the school. However, where possible and reasonable, access should be provided to every door of every building.

Paths, including steps and ramps, must be designed to avoid trip and slip hazards. Paths are generally hard-paved or made of slip-resistant surfaces such as concrete on a crushed-rock base. The use of slip-resistant materials and detailing is an important occupational health and safety (OH&S) consideration.

Surfaces such as gravel and granitic sand are not acceptable due to associated maintenance problems. Permeable surfaces such as rubber, no fines concrete and other surface treatments may be considered, subject to budget and applicability. Recycled concrete aggregate and asphalt may, where feasible, be specified for pedestrian paths. If light pedestrian activity is expected, then asphalt may be used.

Path widths should suit their anticipated usage and, in general, be a minimum of 1500mm wide and in accordance with AS 1428.

Footpaths should be wide enough at building entrances to provide sufficient paved area for students waiting to enter, especially if external access to classrooms is employed.

Path gradients, steps and surfaces should accord with the Building Code of Australia. Some paths may require handrails. Landings of ramps and steps must be provided with tactile ground surface indicators (TGSI). Steps must also be provided with contrasting strip at tread nosings in accordance with the Building Code of Australia.

Paths with gradients greater than 1:14 must be provided with handrails in accordance with AS 1428.1. Paths with gradients greater than 1:20 might also require them (see AS 1428.1).

10.2.6 Hard courts

New Primary Schools

One double hard court is to be provided as well as a paved area equivalent in size to a single hard court.

The hard courts are regarded as an important physical education facility and should therefore be sited in close proximity to the gymnasium and outdoor grassed playing area.

The paved area should be conveniently located for school assembly purposes.



New Secondary Colleges

Two double hard courts are to be provided.

Hard courts should be constructed of light duty asphalt (recycled concrete aggregate and asphalt may, where feasible, be specified). Refer to AS 3727–1993, Table 4, Light Traffic for a recommended minimum standard of construction.

Ensure that an effective and durable edge restraint is provided, extending for the full depth of the pavement including base course. A standard municipal flush kerb is recommended.

Hard Court Marking

Hard courts are usually marked in accordance with Sport and Recreation Victoria (Department of Victorian Communities) guidelines for basketball, netball and volleyball. The courts should be marked in a north/south orientation.

Hard Court Fittings

Basketball and netball fittings should be provided as required, and sleeves should be supplied for any other games posts.

10.2.7 Paved Areas

Asphalt Concrete

Asphalt surfaces shall be heavy duty with appropriate base course material placement and finishing to conform with AS 3727-1993 and the Australian Asphalt Pavement Association guidelines.

Concrete Pavement

Concrete pavements shall be a maximum depth of 150mm with appropriate reinforcement and base course material. Designs shall conform with Cement Concrete & Aggregates Australia guidelines and AS 3727-1993 and AS3600.Segmental Pavers

Segmental pavers shall be heavy duty with appropriate base course material. Placement and finishing to conform to manufacturer’s specification and AS 3727-1993.

Pavement Ancillaries

All pavements should have appropriate concrete edge restraints such as kerb and channel or edge strip. Appropriate agricultural drainage pipes should be used to avoid pavement failure due to water infiltration.



10.3 Playground Equipment

Only approved playground equipment may be erected in school grounds. In general, approved equipment includes:

► sandpits;

► slides;

► horizontal and vertical ladders;

► horizontal bars;

► gymnastic combinations;

► jungle combinations;

► climbing nets and frames; and

► climbing ropes (fixed).

All equipment design and installation should conform to AS 4685.1, AS 4685.2, AS 4685.3, AS 4685.4, AS 4685.5, AS 4685.6, AS/NZS 4486.1 and AS/NZS 4422.

The following items are not approved for use in schools:

► seesaws;

► swings (including log swings);

► maypoles;

► merry-go-rounds;

► roundabouts; and

► flying foxes.

All apparatus must be fixed unless specifically designed to be portable. Concrete footings should be set with the tops of the footings at least 200mm below ground level and backfilled.

Under-surfacing to an average compacted depth of 250mm should be provided and maintained in a loose condition.

In general, playground equipment should not be more than 3 metres above ground level, with a fall height of no more than 2.5 metres. The equipment must be at least 2.5 metres away from any fences, buildings or other similar objects. There should be at least 2.5 metres between items of equipment. Written confirmation that the playground equipment and its installation meet the requirements of the Australian Standards should be provided by the supplier.

All playground equipment should be inspected weekly and repairs and maintenance carried out immediately. Particular attention needs to be given to the under-surfacing beneath the playground equipment.

Information and advice is available from the Play Australia: http://www.playaustralia.org.au/.

Guidelines for School Playgrounds: Playground Safety Management (2012) are also available in the Principal Consultants section of the Victorian School Building Authority eduGate page (https://edugate.eduweb.vic.gov.au/sc/sites/Infonline/default.aspx). (Note: this requires an Edumail user ID and password for access.)

10.4 Fencing

10.4.1 Standard Perimeter Fencing

A perimeter fence to enclose or define the extent of the site should be provided to a minimum height of 1200mm.

Fencing along street frontages should be palisade and may exceed the 1200mm minimum as appropriate. Chain mesh fencing should not be used.

Any adjoining party fencing requirements will need to be investigated by the principal consultant.

10.4.2 Security Fencing

As a general rule, the Department does not provide security fencing in Victorian Government schools. However, provision of a 2100mm high security fence should be considered where local conditions require additional security to minimise casual and opportunistic access and vandalism. Depending on the local circumstances, such fences can not only keep students inside the grounds but can also prevent access to the grounds by unwanted visitors.

The recommended type is palisade fencing, 2100mm high and with vertical bars.

Different levels of security may be considered appropriate for different facilities. Classrooms benefit from a high degree of protection, particularly if the design has lockers located under external verandas. Other areas may still need to be fenced, but to a lesser standard.

Security against unauthorised access can also be achieved through environmental design using landscaping features such as planter boxes and changes in levels.

Careful consideration must be given to gates so that latches and controls are operable by people with disabilities but without compromising security.

10.4.3 Pool Fencing

Pool fencing (conforming to AS 1926.1, Swimming Pool Safety – Part 1 Safety Barriers for Swimming Pools) must be provided for all swimming pool areas.

Careful consideration must be given to gates so that latches and controls are operable by people with disabilities but without compromising security.




10.5 Landscaping

10.5.1 Sports Playing Field

The available stripped top soil resulting from building works should be utilised and spread to assist in creation of flat playing areas. Assessments of the fill required compared with the yield of top soil available from the building site, plus any additional material required, should be undertaken at the commencement of the planning process to define what is practical for the site.

The Department is aware of developers and commercial companies approaching schools to supply fill (soil) from other sites, such as new housing estate developments. School Councils are not authorised to enter into agreements to accept fill without Ministerial approval. School Councils interested in entering into such agreements must contact the Victorian School Building Authority.

All playing surfaces need to be drained with falls across the playing surface and adequate sub-surface drainage. At least two quick-coupling valves should be provided within the playing areas.

All grass mixes should be drought tolerant, with a minimum of flowering species (such as clover) to minimise the attraction of bees.

New Primary Schools

A flat, well drained, grassed open playing area should be provided subject to the dictates of topography and available space (nominal field/oval dimensions of 110 x 90 metres).

New Secondary Schools

A flat, well drained, grassed open playing area should be provided (nominal field/oval dimensions of 165 x 135 metres).

10.5.2 Irrigation Systems

Appropriate water reticulation should be provided to enable grassed areas to be maintained. Quick-coupling valves should be provided in a suitable layout.

The installation of an irrigation system alone may not achieve the best results in water conservation. Systems should be carefully chosen using expert advice where appropriate. An ongoing irrigation management plan is recommended to prevent “over irrigation”. A good example of best practice is the document Efficient Irrigation: A Reference Manual available from the South East Water website: http://southeastwater.com.au/SiteCollectionDocuments/Business/Local-government/Attachment6EfficientIrrigationForTurfAndLandscape.pdf . The South East Water website’s “Irrigation Calculator” is of further assistance.


http://southeastwater.com.au/SiteCollectionDocuments/Business/Local-government/Attachment6EfficientIrrigationForTurfAndLandscape.pdf

http://southeastwater.com.au/SiteCollectionDocuments/Business/Local-government/Attachment6EfficientIrrigationForTurfAndLandscape.pdf


Water Restrictions

The design of planted areas needs to assess the availability of mains water supply under prevailing water restrictions operating in the school location, and also any likely changes in the situation.

Use of harvested rainwater may be possible, assuming this is not already being utilised for the flushing of toilets. Other sources, such as bore water, are also likely to be restricted in times of water shortage.

10.5.3 General Grassed Area

All areas of the site not required for other purposes will be converted to general grassed areas. Trees may be planted through these areas to provide future shade.

Refer Section 10.8 – Landscape Cultivation and Planting Guidelines, for planting information.

10.5.4 Garden Beds

Provide a minimum 150m2 of “ground level” mulched garden beds to match existing grades and site contours, where possible, and service these with fixed water spray systems. The use of a dripper system should be explored in lieu of expensive pop-up sprays. Fixed spray heads should be avoided due to vandalism. Garden beds should be located in less heavily trafficked areas.

Composts and mulches can reduce water consumption and eliminate weed problems, thereby reducing maintenance costs. Composts and mulches made to standards AS 4454 (composts, soil conditioners and mulches), AS 3743 (potting mixes) and AS 4419 (soils for landscaping and gardens) should be employed in landscaping applications where feasible to do so.

Refer Section 10.8 – Landscape Cultivation and Planting Guidelines, for planting information.

10.5.5 Shade Areas

Due to Australia’s high skin cancer rates, sun protection is an important health and safety issue that schools need to address. Providing well-designed shade at the school will help protect students and staff from the sun’s harmful UV rays.

Effective shade provides shelter from the sun’s UV radiation at the right time of day and at the right time of year. Shade alone can reduce overall exposure to the sun’s ultraviolet (UV) rays by about 75%.

Shade should be designed to offer the greatest protection during peak UV radiation times and usage periods. In Victoria, UV Index levels are highest from September to April. About 60% of daily UV radiation reaches the earth’s surface during the middle of the day. Therefore, sites with high usage at that time have a higher priority for shade.



When planning for shade, refer to the SunSmart Shade Guidelines available from the SunSmart website: http://www.sunsmart.com.au/downloads/resources/brochures/shade-guidelines.pdf .

When planning school grounds, consideration should be given to developing shade areas appropriate for student use. SunSmart recommends that shade audits be conducted to:

► establish usage patterns at the site;

► determine the daily/seasonal movements of the sun;

► assess the quantity and usability of existing shade;

► assess the need for additional shade; and

► provide recommendations concerning additional shade (if required).

The best types of shade have extensive overhead or side cover, and are away from highly reflective surfaces. The shaded area should also be an inviting space so that students will want to use it.

When planning school grounds, consideration should be given to developing appropriate shade areas for student use. This can be done in a variety of ways.

Natural Shade

Natural shade should be a major element of shade provision within a school. Trees with dense foliage and wide spreading canopies provide the best protection.

Where possible, preserve all existing and suitable shade trees on site. Optimise the use of this existing shade by, for example, removing low branches so that students can play underneath.

For the longer term, locate shade planting in areas where students tend to gather, such as lunch and passive playground areas. The “shade tree chart” on page 19 of Shade for Everyone provides information to help select trees appropriate to the site. Plant groups of trees in clusters to increase the overall size of the canopy and therefore increase protection.

Built Shade

As trees can take years to grow, it is recommended that built shade be constructed in the shorter term. Note that shade sail structures require building permits and engineering certification.

Shade structures must be made in accordance with Building Code of Australia and Australian Standards. Any shade structure in fixed play equipment areas should be designed with reference to AS/NZS 4486.1:1997. The UPF (ultraviolet protection factor) rating system for shade fabric is presented in AS/NZS 4399:1996. SunSmart recommends that shade fabrics have a UPF of 15 or higher. These offer 90% protection from UV radiation. The shade area should be of sufficient height (three metres minimum) to make it light and airy and a welcoming space to use.

Safety is a major consideration when designing built shade:


http://www.sunsmart.com.au/downloads/resources/brochures/shade-guidelines.pdf


► Columns and posts should be clearly visible, with rounded edges and/or padding, and located to minimise intrusion into play and circulation areas.

► Cables and guy ropes should be avoided where possible. If required, locate them in garden areas and provide marking and padded protection.

► Vertical barriers at the sides of the shade structure should be designed to prevent climbing.

Design shade structures to reduce indirect UV radiation. Modify or select surfaces to reduce reflected UV radiation, for example, replace smooth concrete with brick, grass or tanbark. Vertical surfaces such as walls should also be made of materials that reduce reflected UV radiation (for example, brick).

10.5.6 Landscaping in Bushfire Prone Areas

Bushfires are a natural and challenging feature of the Victorian landscape. Well planned and managed vegetation can provide many benefits in bushfire-prone areas. It can:

► reduce fire intensity;

► reduce wind speed;

► deflect and filter embers (small particles of burning material and other burning debris); and

► provide shelter from radiant heat.

The school’s site plan can be used to develop a plan which incorporates planting and landscaping. All external features on site need to be considered, for example, overhead wires, existing trees and shrubs, hard areas, service areas, paths and roadways, playgrounds and sports fields.

For more comprehensive information, refer to the Department’s Landscaping Guidelines for Bushfire Prone Areas. Also see Section 10.8 – Landscape Cultivation and Planting Guidelines.

10.6 Covered Ways

Covered ways link both permanent and relocatable facilities.

In general, the covered way is a simple structure that comprises a galvanised frame with metal roof decking. Roofing and guttering shall be provided in accordance with Section 6.4 – Roof.

In the case of new school developments, covered ways should be provided to link relocatable units with permanent buildings. It is normal practice for relocatable buildings to be sited in cluster arrangements along a central covered way access spine. Take-offs from the central covered way are to be provided at entrance points.

Covered ways may also be considered as a means of providing undercover external access around and between permanent buildings. They can also provide useful shade to buildings and windows. This should be addressed by the principal consultant as part of the building design process.



10.7 Improvements (new schools) – Landscape Finishes

10.7.1 Seating

Formal outdoor seating (100mm length per student and an overall school minimum of 20 metres) shall be provided. Seating configurations should take into account prospect/vista, shade, age group, gender and their benefit in terms of social development and interaction.

10.7.2 Litter Bins

Outdoor litter bins (one for every 30 students and a school minimum of one) shall be provided.

10.7.3 Flagpole

One flagpole, with all the attachments needed to raise a flag, shall be provided.

Security may be advisable to avoid unauthorised use.

10.7.4 External Signage

A system of external signs listing different parts of the school and clearly directing people to their intended location should be provided. It is of particular importance that signs at the entry to the site clearly direct visitors to the school office.

Signs are important for both delivery and periodic maintenance, and should be vandal proof, informative, accurate and visually interesting. Signs are labels which establish a tone and, as such, are key to many first and lasting impressions.

Signage must comply with the Disability (Access to Premises – Buildings) Standards 2009 and the Building Code of Australia.

Wayfinding (referring to the ways in which people orient themselves and navigate from place to place) for all is required.



10.8 Landscape Cultivation and Planting Guidelines

The development of school grounds and cultivation of school gardens has important practical and aesthetic benefits.

Deciduous trees to the north (or evergreens set back a distance twice their height), and evergreens to the east and west can block summer morning and evening sun if external blinds are not provided. The maintenance costs of deciduous trees should be considered.

10.8.1 General Planting Hints

► Approximate planting distances:

: Plants of up to one metre (300mm to 600mm apart);

: Plants from one to two metres (one metre apart); and

: Plants from two to two and a half metres (one and a half to two metres apart).

This allows for the usual 30% death rate.

► Plant eucalypts and other large trees within a suitable distance from buildings and sewerage. This ranges from two to six metres, depending on the size of the tree. The distance from the tree to any building should be at least the anticipated height of the mature tree.

► Trees in clumps look more natural if planted in uneven numbers. Vegetation groupings should create significant places and gestures within school grounds.

► Plant several clumps of one particular type. For instance, five clumps of different species of acacias, melaleucas or eucalypts would emphasise the diversity of plants within each genus; while flowering times, fragrance, texture and leaf shape are some of the variables within each genus. A suitable area for such planting would be an unused corner at the edge of an oval or playground.

► Avoid planting trees under the eaves of classrooms or planting tall shrubs in front of windows. Judicious planting, however, can shade some windows and provide a cooling effect. Deciduous trees offer shade in summer and let in the light during winter.

► Plant shade trees near car parks. Avoid limb droppers and troublesome root systems – Refer to Section 10.8.3 for a list of plants to avoid.

► Avoid planting trees with large seed pods, such as Eucalyptus ficifolia, near hard-paved areas. Children can slip on these pods.

► Avoid thorny, poisonous or fruit bearing plants. Refer to Section 10.8.3 for a list of plants to avoid.

► Before planting native trees, attempt to find out which trees and plants are indigenous to the area. Such plants have a high success rate and are valuable in terms of local ecology.

► Plant shrubbery areas thickly so that weeds won’t survive.

► In general, shrubs will grow as wide as they are high, and for this reason “one metre” garden beds are not useful planting areas.



► Small or established trees:

: for native trees, results are better with small trees, particularly in hard soils; and

: in areas of high traffic, established trees are suggested.

10.8.2 Vegetation Fuel Management

Combustible material is a major factor influencing the intensity and spread of bushfires. When developing a landscaping plan, consideration should be given to fuel management. Consider the following strategies:

► if planting close to buildings, choose native or exotic grass species that remain green throughout summer;

► less flammable ground cover plants can reduce the travel speed of fire;

► avoid plants that produce fine fuel which is easily ignited (fine fuel includes tree and shrub litter, leaves, twigs, bark strips, mulches, ferns, low plants, grass, decaying material and debris on the ground);

► do not plant trees that are particularly combustible, for example, trees with ribbon bark, open crown, fine leaves or high oil content;

► create breaks between fuels along the ground – plant islands, rather than continuous runs of vegetation;

► form breaks between fuels vertically – plant in such a way that fuels cannot form a continuous or linked ladder from ground-level grasses to bushes, and from understorey to tree tops;

► consider the position and nature of existing trees; make sure that new planting will not create a fuel ladder with these trees;

► if planting to provide shade, choose species with dense foliage and spreading canopies;

► as a general rule, plants which grow to a height greater than four metres should not be closer than ten metres from any structure; and

► look at descriptions and plant dimensions when selecting plants, but also observe how particular plants grow in your area. (Refer Section 10.8.4 – Particular Plants – Bushfire Prone Areas)

Section 11:Workplace Health & Safety

Brighton Secondary College Architect: Hayball183

Department of Education and TrainingSection 11 – Workplace Health & Safety

11. WORKPLACE HEALTH & SAFETY

11.1 Safety in Design

The issues noted in this section require consideration during all phases of the project. Note that legislation places requirements on designers, owners and management of all workplaces.

The PREP Design Development Report must show that the design complies with Section 28 of the Occupational Health and Safety Act 2004. An acceptable approach is for the principal consultant and school to review potential risks involved in the project design, and to provide either solutions to eliminate the risk or a means of control for each risk, so far as is reasonably practicable.

A basic reference is the WorkSafe Victoria publication, A handbook for workplaces – OH&S in schools – A practical guide for school leaders. A particularly useful section is “Addressing Key Risks in Schools” (page 12) which provides a list of risks and examples of control measures.

While legislation in Victoria does not yet extend to design for safe construction, consideration of the way in which the building needs to be constructed, and elimination or amendment of design features which are difficult to build, will yield benefits in the areas of cost and time control.

11.2 Victorian Occupational Health and Safety Act 2004

This Victorian legislation places an obligation on owners and designers of buildings and employers to ensure that all persons employed (including contractors) in or on their premises are provided with safe workplace conditions.

Reference needs to be made to the Occupational Health and Safety Regulations 2007 for such matters as prevention of falls, hazardous substances (including asbestos), and hazardous industries – construction.

The implications of the Victorian Occupational Health and Safety Act 2004 apply generally across all kinds of building projects and the built environment and are not unique to schools. An obvious area of hazard is access to roofs (see Section 4.04).

Under Department Circular S434–2007 Occupational Health and Safety Act – Duties of Designers, principal consultants are required to comply with Sections 27 and 28 of the Victorian Occupational Health and Safety Act 2004. In consultation with the school, consultants must develop a list of potential risks associated with the identified workplace and user activities. Schematic design and design development reports are to be accompanied by a statement from the school that it has considered the design from an OH&S perspective and is satisfied that it provides a workplace that will be safe and without risk to health.



11.3 A Handbook for Workplaces – OH&S in Schools – A Practical Guide for School Leaders

This WorkSafe Victoria reference should be consulted as part of the process in the design of school projects. A summary of selected items is provided here for reference:

Reference Comment Action

Roles of School leadership – p.6

Liaising with building designers to ensure that new buildings and renovations and alterations to existing buildings are designed to provide a safe environment (i.e. eliminating risks through good design).

Design to provide a safe environment.

Risk – p.14 Likelihood of injury from handling heavy equipment.

Control by provision of adequate storage for heavy items at heights between knee and shoulder level.

Risk – p.15 Likelihood of injury from hazardous ways of handling and accessing materials in classrooms, etc.

Control by designing storage areas to reduce turns and distances that need to be crossed, provide for use of trolleys, provide adequate storage.

Risk – p.18 Injuries resulting from slips, trips and falls from:

uneven ground

wet/slippery floors

trip hazards.

Eliminate risks through good design.

Flooring – slip-resistant, changes of level highlighted.

Stairs – high visibility, correct handrails, suitable covering re maintenance.

Roofs – devise means of retrieving balls.

Environment – glare off shiny surfaces, dim light, floors wet by rain or condensation, spill resistance.

Risk – p.19 Slip and trip, and falls, and impact injury at stairs and steps.

Slip-resistant surfaces.

Slip-resistant steps at nosings of treads.

Luminance and colour-contrasting strips at nosings of treads (incorporating slip

Consideration should be given to installing photo-luminescent strips at tread nosings and elsewhere in stairways and egress routes.

Risk – p.19 Slips in general environment. Slip-resistant surfaces.

No areas where water or grease can accumulate.

Slip-resistant strips.

Mats at entries recessed or with tapered edges (refer the Building Code of Australia).

Avoidance of trailing power leads.

Risk – p.19 Trips in general environment. Secure floor coverings and entry mats.

Avoid low level obstacles.

Provide suitable places for bikes.

Provide storage for personal items.

Risk – p.19 Falls from roofs. Pitch roof so that balls fall back to ground level.

Designate staff members to retrieve balls using suitable equipment such as extended-handle ball retrievers.

Provide guards to skylights or use impact resistant materials to prevent falls through skylights.

Risk – p.20 Health and safety of contractors. Provide safe access to enable maintenance to plant on roofs, repairs to roofs, cleaning gutters (See Clause 4.4.2.1.8 Safe Access to Roofs).



11.4 Sub-floor Spaces

Sub-floor spaces must be closed off from access by children.

The 2005 post-occupancy evaluation reported a school built on a sloping site where floors had been designed as suspended timber floors to minimise costs and excavation. The sub-floor spaces were high enough for children to enter and had not been closed off as part of the design, creating an area where children were unsupervised and at risk of injury.

11.5 Hazardous Materials and Conditions

The school’s Occupational Health and Safety Representative should (before the commencement of any demolition, refurbishment or maintenance works) ensure that the builder/contractor arranges an examination of the building structure, equipment, fittings and all parts of the site by a competent specialist to determine, as far as practicable, the presence of noxious, toxic or explosive materials or conditions hazardous to the health of the school community or public if disturbed.

The nature and location of each hazard shall be recorded by the builder/contractor, and both the record and the proposed method of dealing with identified hazards should be included in a work plan. The principal consultant in conjunction with the Department’s Program Manager is responsible for the receipt and management of this information, including identification of special factors that may have cost implications, etc.

For further information, refer to Australian Standard AS 2601.

To ensure that principal consultants have carried out their duties in accordance with all occupational health and safety requirements, they need to submit monthly reports to the Program Manager who, in turn, will collate these and submit them to the Department (likewise on a monthly basis).

11.6 Asbestos

It is the Department’s aim to ultimately remove asbestos from all school buildings. While the most dangerous forms of this material have been attended to, asbestos-containing materials are still present in many existing facilities.

Asbestos management is governed by Occupational Health and Safety Regulations 2007, Chapter 4 – Hazardous Substances and Materials, Part 4.3 – Asbestos.

All schools have had a Division 5 Asbestos Register (previously known as Asbestos Audit) carried out in accordance with Division 5 of the Occupational Health and Safety Regulations 2007. This details the presence of any known visual asbestos-containing materials within the school.




Before undertaking any maintenance, refurbishment, capital or demolition works, a school-appointed School Asbestos Co-ordinator will ensure that works involving the removal or disturbance of asbestos are carried out by contractors licensed by the Victorian WorkCover Authority, and that they have the required level of public liability and current asbestos insurance.

The School Asbestos Co-ordinator must ensure that the builder/contractor responsible for the management and/or removal of existing asbestos material in school buildings complies with Occupational Health and Safety Regulations 2007, Chapter 4 – Hazardous Substances and Materials, Part 4.3 – Asbestos.

The principal consultant’s role in the course of a major building project is to:

ensure that a Division 5 Asbestos Register is included within the tender documentation or made available to tenderers during the tender process;

ensure that a Division 6 Asbestos Register (detailing the condition of the area to be worked in) is undertaken prior to the commencement of any project works;

liaise with contractors prior to the commencement of any project works;

liaise with contractors during the progression of works to ensure all that mandatory regulations are adhered to; and

ensure the contractor conforms to the Department’s Asbestos Management Plan.

The following are requirements for asbestos works on Department sites:

the school site is to be totally vacant during all asbestos removal works;

all asbestos materials within the construction zone shall be removed as part of the project; and

at the completion of the project, the principal consultant shall be responsible to arrange a new Division 5 Asbestos Register and provide copies to the Department and the school.

11.7 Copper-Chrome-Arsenate (CCA) Treated Timber

Copper-chrome-arsenate (CCA) treated pine must not be used in any exposed location where students or members of the public are likely to come into intimate and frequent contact. For a list of alternative timbers to be used, refer to AS 5604–2005.

AS 5604–2005 identifies the different durability characteristics of various natural and untreated timbers, and specifies timber types suitable for use under various circumstances.

The suitability of timber treatments is identified in AS 5605–2007 (Guide to the Safe Use of Preservative – Treated Timber).

Specific information on particular treatments can be found in the following consumer safety sheets:

AS 5605 Supplements—Consumer safety information sheet;



AS 5605 Supp 1 Guide to the safe use of preservative-treated timber – Consumer safety information sheet - Copper chrome arsenate (CCA)-treated timber;

AS 5605 Supp 2 Alkaline copper quaternary (ACQ)-treated timber;

AS 5605 Supp 3 Copper azole-treated timber;

AS 5605 Supp 4 Guide to the safe use of preservative-treated timber – Consumer safety information sheet - Light oil/organic solvent-borne preservatives (LOSP)-treated timber;

AS 5605 Supp 5 Creosote or pigment-emulsified creosote (PEC)-treated timber; and

AS 5605 Supp 6 Bifenthrin-treated timber.

The Building Code of Australia, Part I, also requires the maintenance of safety measures and equipment including:

► building fire integrity;

► means of egress;

► signs;

► lighting;

► fire fighting services and equipment;

► air-handling systems;

► automatic fire detection systems;

► occupant warning systems;

12.4 Termites

One aspect of maintenance gaining increased attention is the control of termite activity. All school projects should now incorporate protective measures against termite attack on the buildings forming part of the project. These measures create barriers to concealed access but do not ensure permanent protection against termites without active and ongoing maintenance. Maintenance requirements applying to the selected system of protection should be communicated to the school in its operation and maintenance manuals.

The Department publication Use of Termiticides in Schools provides advice in this regard (https://edugate.eduweb.vic.gov.au/sc/sites/Infonline/Health%20and%20Safety/Protocol%20for%20Use%20of%20Termiticides%20in%20Schools%20(2006).pdf ).

Each provision should be separately itemised.

As the cost schedule is based on fixed price (lump sum tenders which already include contingencies and escalations), no further amount is added to the budget for a school for these sub-elements.

The amount for fees covers only consultants; fees associated with services (electricity, etc.) and lodgements (permits, etc.) are included with the relevant element.

Loose furniture and loose equipment are separate from fitments (15 FT) and special equipment (16 SE). These latter are usually installed or fixed in place as part of the building contract. The cost of loose furniture and loose equipment need not necessarily be included in this contract or attract consultant fees. A decision on this matter should be made for each project.

Where some part of a building will be due for maintenance during the period that the builder is in possession, on-going maintenance may be included in the building contract. A decision on this matter should be made (and the cost determined) for each project.

Note: Builders Work and Allowances

Where work on engineering services and the like is performed by nominated sub-contract or separate contract and included in any element, any monetary allowance for builder’s profit and attendance on the nominated sub-contract or separate contract and any builder’s work in connection therewith shall be included with the element concerned.
