National Course Specification: course details


RATIONALE

This is a specialist course providing an opportunity to study materials, processes and principles ofconstruction associated with low-rise buildings. It will contribute to the development of appropriateskills and knowledge for the built environment candidate and will make a significant contribution tohis or her general education and personal development through promotion of the core andtransferable skills important for future employment within the construction industry. The course will enhance the general education of the candidate by exposure to this exciting industry.The development of vocational competencies will also raise generic skills in communication,interpersonal relationships, logical, analytical and problem-solving, information collection andretrieval. Candidates will then be prepared for the future development of supervisory andmanagement skills. The course is designed to introduce the candidate to the types of solutions available when agreenfield site is to be developed for low-rise buildings. The course is intended to provide a soundappreciation of applied terminology, principles and techniques of building and architecturaltechnology, use and application of materials, methods of positioning and securing components,sequencing of operations, and the need to comply with recognised practices and relevant legislation. The course should appeal to those candidates who aspire to a practical creative career, enjoyteamwork, and seek variety in their work. It provides an important step both in the development ofconstruction skills and on the academic pathway to construction professional status. Candidates whohave studied Physics, Technological Studies, Craft and Design or Graphic Communication will findHigher Building and Architectural Technology to be an natural extension of their previous study. The course is particularly relevant for the candidate wishing to pursue a career in the constructionindustry, including occupations involving planning, programming, designing, detailing, measuring,taking-off, estimating, building control, quality control, supervision and inspection. Candidates may wish to progress to other specialist areas of the DET framework, such asConstruction, Civil Engineering, Land Use (Built Environment), or Building Services. This coursealso provides an appropriate entry point for candidates contemplating a career in Architecture,Quantity Surveying, Construction Management, Civil and Structural Engineering, Planning orBuilding Services. The units of Higher Building and Architectural Technology are also included in two of the ScottishGroup Awards in Construction. These awards are designed for candidates who wish to follow atechnician route in the construction industry. The component units of Higher Building andArchitectural Technology therefore provide some of the underpinning knowledge for ScottishVocational Qualifications (SVQs) which are based on the Construction Industry Standing Conference(CISC) occupational standards.


National Course Specification: course details (cont)


The aims of the course are to develop: • a systematic and logical approach to planning and sequencing construction operations• skills in constructional detailing• an appreciation of the uses and limitations of components and materials• an understanding of the functional considerations for the specification of components and

finishes• an understanding of design considerations in relation to the relevant building regulations,

British Standards and Codes of Practice Satisfactory completion of the course should provide the candidate with: • a sound knowledge of the factors affecting site preparation• a clear understanding of the relevance of planning and dimensional positioning• the ability to detail constructional work and specify appropriate components and materials• a positive attitude to the importance of shaping the built environment by the construction

industry• the ability to absorb, interpret and transmit information in graphical, spoken and written forms

COURSE CONTENT

All of the course content will be subject to sampling in the external assessment.

Each of the component units of the course highlights a key stage of the construction process.Completion of the Higher course with its external assessment component, in addition to thecompletion of the individual units, will provide candidates with a sound grasp of the principles ofbuilding and architectural technology related to the construction of low-rise buildings on greenfieldsites. Completion of the Higher course will enable the candidate to apply the various stages ofconstruction activities from planning the site to the development of a project.

To encourage the integration of knowledge and skills, and to assist candidates in the development oftransferable skills, it is recommended that the two units are presented concurrently rather thansequentially. The additional 40 hours assigned to the course will allow candidates time to develop arelated project and prepare for external assessment, to carry out further research and to practice theintegration of the skills acquired through study of the individual units of the course.

BUILDING TECHNOLOGY – PRINCIPLES AND PROCESSES

The following topics will be covered:

Site establishment

The emphasis of this unit is on allowing the candidate to develop skills in the planning of a site. Thisincludes the selection of a location for the site access, temporary roads, storage ofmaterials/components and temporary accommodation which is realistic in terms of allowingconstruction work to proceed in an efficient and effective manner. The specification of materials fortemporary roads should also be covered. In considering site safety and security, reference should be




made to the solutions adopted for security of the site and the protection of the public duringconstruction work. The provision of the following temporary services should also be covered:electricity, water supply, telephones and foul drainage.

Substructure construction

Study of this aspect might best begin with a brief introduction to the techniques and objectives of siteinvestigation, covering desk study, walk over and ground investigation. Reference should be made tothe techniques adopted for the ground investigation, namely trial pits and bore holes, together withinformation gathered from in situ testing and laboratory testing. In situ testing should include thecone penetration test (CPT), standard penetration test (SPT) and the field vane test. Laboratorytesting should include pH, sulphate, moisture content and particle size distribution. Excavation andearthworks should include foundation trenches, pits and earthwork support. Reference should bemade to the specification for fill materials and their correct compaction on site.

Simple foundation types should be limited to strip foundations, pad foundations, raft foundations,short bored piles and ground beams. Types of reinforcement used should be mentioned and thereasons why they are incorporated in the foundation. Reference should be made to the techniquesadopted on sloping sites.

Specification and supply of concrete mixes for foundations should include designated mixes andstandard mixes detailed in current standards (BS 5328: Parts 1-4: 1991). Reference should be made tothe correct methods for transporting, placing, compacting, curing and protecting the concrete.

Substructure walling, including the support for floors, position of damp-proof courses, damp-proofmembranes, service entries and sub-floor ventilation, should also be included.

Safety aspects of superstructure work should be stressed.

Superstructure processes

This study should cover the processes relating to the superstructure of a building. The followingshould be covered:

1 erection of structural steel and precast concrete frames2 cladding to framed buildings, including infill panels and profiled sheeting3 performance requirements of floors, walls and roofs4 construction of loadbearing walls and floors5 construction of pitched roofs and flat roofs

In selecting materials, candidates must takeaccount of the performance requirements of the various elements of a building, including walls,windows, floors, ceilings, flat and pitched roofs.




ASSESSMENT

To gain the award of the course the candidate must achieve all the component units of the course aswell as the external assessment. External assessment will provide the basis for grading attainment inthe course award.

When units are taken as component parts of a course, candidates will have the opportunity todemonstrate achievement beyond that required to attain each of the unit outcomes. This attainmentmay, where appropriate, be recorded and used to contribute towards course estimates, and to provideevidence for appeals. Additional details are provided, where appropriate, with the exemplarassessment materials. Further information on the key principles of assessment are provided in thepaper Assessment, published by HSDU in May 1996.

DETAILS OF THE INSTRUMENTS OF EXTERNAL ASSESSMENT

Part 1

A project devised by the centre, based on an SQA specification. This will be internally assessed andexternally moderated. The project will constitute 30% of the total external assessment and willrequire candidates to draw on knowledge and skills developed across the two component units of thecourse and to apply such to the development of a small housing scheme with an adjacent smallcommercial building. It is important to note that the project could be extended to generate all theevidence for internal unit assessment.

The project will provide candidates with the opportunity to apply knowledge and skills in lessfamiliar contexts and in the solution of more complex problems.

The specification for the project will provide a structure and clear parameters which will allowevidence to be generated for:

(a) external assessment for a pass at level C and an award at A(b) internal assessment of a number of unit outcomes

Relevant performance criteria for internal assessment will be identified in the project specification.

The total mark for the project will be 100.

Part 2

A 3 hour examination paper externally devised and externally assessed. The paper will constitute70% of the total external assessment. It will comprise sections A and B. Candidates will be requiredto attempt all questions in section A and three questions from five in section B.

The total marks for the paper will be 100 of which 40 will be allocated to section A and 60 to section B.

Section A will feature five short answer and/or restricted response questions examining thecandidate’s knowledge and understanding of construction principles, processes and materials acrossthe two component units.




Section B will feature five structured and/or extended response questions examining the candidate’sknowledge and understanding of building design and technological processes.

GRADE DESCRIPTIONS

The descriptions below are of expected performances at Grade C and at Grade A. They are intendedto assist candidates, teachers, lecturers and users of the certificate and to help establish standardswhen question papers are being set. The grade of the award will be based on the total score obtainedin the examination.

The grade descriptions below indicate the nature of achievement which is required for the award of agrade C and a grade A in the course assessment.

At C

Candidates can:

• use appropriate knowledge and understanding acquired through study of the component units• demonstrate a depth of understanding by, for instance, explaining the processes associated with

substructure and superstructure construction or by designing and detailing stair layouts• demonstrate the ability to integrate skills acquired in component units, for example, by

preparing proposals for the development of a small building site• provide a completed project report At A

Candidates can:

• provide technical descriptions of materials and components used and carry out comparisons ofperformance

• complete an appraisal of construction proposals by, for example, confirming compliance withcurrent legislation and British Standards

• produce a well-structured report containing, for example, conclusions and suggestions forrefinements and improvements to construction proposals

APPROACHES TO LEARNING AND TEACHING

Where appropriate, arrangements should be made to ensure that there will be no artificial barriers tolearning and assessment. The nature of a candidate’s special needs should be taken into account whenplanning learning experiences and selecting assessment instruments. Alternative arrangements can bemade as necessary. Although each of the component units may be taught sequentially, concurrent delivery is preferredsince this will allow candidates to gain an early appreciation of the overall process of constructinglow-rise buildings. It is not, however, recommended that delivery of the units be integrated.




Site visits, video presentations and slide presentations of recent building projects will help candidatesrelate construction principles and techniques to practical industrial situations. The study of buildingand architectural technology should be based on actual projects or hypothetical but realistic casestudies. Use should be made of the following: • current British Standards• Building Research Establishment digests, information papers, good practice guides, and defect

action sheets• current Building Standard (Scotland) Regulations

Throughout the course, contact with the building industry should be encouraged through site visits,investigations, visiting speakers, etc. This will help candidates to feel more involved with the industryand motivate them to further study. Issues of construction safety, quality and environmentalawareness and responsibility should permeate the learning and teaching process.

The additional 40 hours assigned to the course will allow candidates time to develop a project andprepare for external assessment, to carry out further research and to practice the integration of theskills acquired through study of the individual units of the course.
