2.1.2 In rastructure and Utilities

The basic utilities such as treated water supply, telephone and electricity lines

are immediately available. However, the relevant authorities should be given

adequate notice of the projects requirement, to enable the relevant agencies

to make the necessary preparation or upgrading works to meet the additional

demand posed by the project. Drainage does not seem to be a problem as

water can be discharged into Jikang River.

2.1.2.1 Electricit

Electricity for the proposed project will be connected from the existi ng

electrical mains near the project site. The electrical line is connected to

the grid network of electricity supply in the state via the SESCO sub-

station designed for the proposed project earlier.

2.1.2.2 Treated Pipe Water Suppl

Treated pipe water shall be connected to the proposed project site via

the existing water supply pipeline. An elevated water tower with a

capacity of 180 m shall be constructed at project site as indicated in

Figure 2.3. The elevated water tank/reservoir of 180m in capacity

shall adequately provide for approximately 1,500 PE (for an average of

0.12 m/person/day). The elevation and cross-sectional details of the

high level water tank are illustrated in Appendix V.

2.1.2.3 Telecommunication

Telephone and facsimile lines are available in the area. The relevant

authorities shall be informed in advance so that the necessary

upgrading works could be implemented in tandem with the project

development. This is to ensure that unnecessary disruption s, for

example due to line congestion and so on, to the existing users are

minimised.

2.1.2.4 Road Net ork

An existing tar-sealed Julau Feeder Road was available and indicated

in Figure 2.3. A network of internal roads had been designed for the

convenience and efficient function ing of the proposed project (see

Roads and Drainage Plan in Appendix V).

ABC Sdn Bhd 2-6

2.1.2.5 Se age and Solid Waste Management

The proposed project had been designed to utilise independent central

sewage treatment plant (SPT) for the treatment of the sewage. The

SPT is capable of treating raw sewage and the system will be equipped

with overflow pipes connected to monsoon drain.

Solid wastes generated by the proposed project activities are managed

by making prior arrangement with the municipal council to regularly

collect and dispose off the garbage. The municipal shall be responsible

for the disposal of the collected waste at municipal approved

dumpsites.

2.2 PROJECT SCHEDU E

The development of the proposed project commenced on 15 August 2008, and will

take about 27 months to complete. Earthwork will take a few months to properly fill

and compact the project site to design level. Its scheduled completion is targeted by

14th November 2010.

2.3 PROJECT ACTIVITIES

Various primary activities normally associated with a project of this nature at differentstages of the development include the followings :-

y Site Investigation,

y Site Preparation,

y Construction,

y Operation and maintenance, and

y Abandonment.

2.3.1 Site Investigation

The activities carried out during this stage are geotechnical investigation, land

surveying works, soil sampling, channel diversion and environmental study.


7/16



ABC Sdn Bhd 2-7

2.3.1.1 EIA Stud

An EIA study is considered necessary to ensure that the proponent is

fully aware of the various measures that may need to be undertaken to

ensure that the project is implemented in an environmentally friendly

manner.

Thus, the study was conducted to assess the potential impact of the

project on the environment as well as to explore the various options

available to ensure that the project development continues to be

implemented with minimal impact on the environment.

2.3.2 Site Preparation

The project site is partially located on hilly land covered with rubber trees.

During the site visit, the project site was been partially cleared. Sitepreparation will entail the clearing of vegeta tion within the project boundary.

Boundaries were tagged or marked before clearing activities commenced.

During clearing, tree felling and clearing activities must be confined to the

proposed project site only. The project contractor shall avoid unnecessary

felling of crop trees along the edges. Site clearing involves cutting, removal

and disposal of everything above the ground level. Biomass consists of tree

branches, stumps, logs, undergrowth, long grasses and loose vegetative

materials.

Biomass will be collected and/or stacked at the northern vacant land of the

project site for natural degradation. If burning is the alternative, then burning

permit must be obtained from NREB in advance. Dumping vegetative and

earth wastes into waterways or streams is strictly prohibited. Clearing are

confined to construction site. The main operating equipments to carry out

these activities are bulldozers, excavators, compactors, and chainsaws.

Exposed soil surfaces and open spaces must be immediately established with

turf grass such as AxV n VW

X Y ` V aW

b c Y Y X Y and any suitable leguminous cover

crops.

2.3.3 Construction

The construction and completion of the proposed project shall consist of

several components, namely, earthworks, filling, embankment, turfing, and

construction of interior roads, drainage and buildings. The operating

equipments involved at this stage are crane, bulldozers, diggers, excavators,


8/16



ABC Sdn Bhd 2-8

scraper, and trucks. The various activities associated with the development

stage include:

y Mobilisation;

y Establishment of site office and workers accommodation;

y Site preparation temporary access, diversion channels and

earthworks;

y General construction construction of internal roads, drainage,

culverts and buildings;

y Traffic generation during construction Stage;

y Disposal of construction waste; and

y Landscaping.

2.3.3.1 Mobilisation

Mobilisation refers to the process of transporting heavy machinery and

plants to site needed for the project development; for example piling rig

and excavators. Julau Feeder Road and KJD Road are the primary

access routes.

2.3.3.2 Excavation and Filling

The project ground is located on a continental soil with calcerous

sandstones and siltstones on a secondary forest , and therefore the

ground level is generally undulating or hilly . For this project, the

proponent aims to attain balanced cut-and-fill volumes within the site,

while maintaining the design platform levels ranging from 19.0 to 31.0

MSL as indicated in Earthwork Layout Plan in Appendix V and

Plates 1, 4, 5 and 6 (C apter 3). Fill materials shall be acquired from

higher elevations within the boundary of project site and fill them on

lower sports of the site to design levels.

For this project, an estimated soil volume of approximately 280,000 m3

shall be cut from the higher spots and filled on relatively lower grounds

to design levels within the site boundary. Mathematically, it is extremely

remote that additional fill materials will be needed, or excess cut

materials will have to be transported out of site. However, a layer of

topsoil shall be excavated so that suitable fill can be used in its place.

Excavated topsoil will be stockpiled on site boundary before it is

restored on the site for landscaping or to support plant growth for

erosion control.

2.3.3.3 Establis ment o Site O ice and Workers

Accommodation

This relates to the construction of temporary workers accommodation

workshops (if any), storage sheds and site office. The project shallestablish a base camp that may consist of site office, fuel depot,

storerooms, workers quarters for the proposed Project. Some of the

labour forces are from nearby areas, i.e. Sibu, Julau and/or from other

areas such as Bintangor and Sarikei.

2.3.3.4 Site Preparation

The construction of infrastructures includes the building of drain

network and internal road network. The perimeter and internal drain

networks serve as effective channels for surface runoffs from the site.

The internal roads serve to facilitate the mobilisation of construction

machineries and the transportation of construction materials to site and

within the site.

2.3.3.5 Embankment

Embankments are generally constructed from excavated materials

nearby, and are predominantly carried out using excavators

(comparatively a much better choice over other construction equipmentwith respect to workability and practicality) . Fill materials must be well

compacted to produce comparatively less erodible materials against

the erosive actions of rainfall.

2.3.3.6 General Construction

General construction refers to the construction of the various buildings

and related facilities associated with the proposed project.

2.3.3.6.1 Construction of Internal Roads

When the existing ground is filled to the designed profiles,

the finished sub-base will be topped up with road base

materials (consisting of rock materials, mainly) and wearing

stability (consisting of asphaltic materials). Compaction

activity shall be carried out using suitable compaction


10/16



ABC Sdn Bhd 2-10

equipment. At this stage, activities anticipated are

transportation of aggregates, laying and compaction of

aggregates.

The wearing course consists of a premix-wearing course

(Asphalt concrete) constructed on a base course. Activities

consist of careful and thorough cleaning of road base,

furnishing and applying bituminous priming material in

accordance with the JKR Arahan Teknik (Jalan) 5/85. The

design life is taken as fifteen (15) years from year of

completion of construction in Year 2010. For this pavement

design, a sub-grade CBR value of 5% is adopted.

The components of the pavement for this design consist of

the followings:

y Premix surface (Wearing Course and Binder Course).

y Base course (crushed aggregates).

y Sub-base course (crushed aggregates).

Road furniture such as traffic signs, road markings and road

shoulders shall be prepared when the road is near

completion. The design structure of the road furniture and

shoulder shall follow the JKRs Specification for Road Works

(1988).

2.3.3.6.2 Construction of Drainage System and

RC Culverts

The construction or installation of drainage structure will

usually be carried out simultaneously during earthwork and

site clearing activities. Other activities include haulage or

removal and disposal of excavated materials, and shaping

and finishing of earthworks involved in accordance with the

approved plan and specification.

When the existing ground shall be excavated and filled to the

designed elevations, and compaction activity will be carried

out using suitable compaction equipment. The framework of

the culverts will be built according to design specifications,

and to be followed by pouring of mortal to complete the


11/16



ABC Sdn Bhd 2-11

culverts. The castings of the culverts include the casting of

the base, wall and top of the culverts.

2.3.3.6.3 Construction of Building

Activities associated with structural construction include

piling, laying of steel bars and BRC mesh, concreting andhoisting of construction materials. Heavy construction

equipment such as piling rigs are utilised at this stage.

2.3.3.7 H drological Anal sis

Hydrological analysis involves the determination of catchment runoff

based on the catchment characteristics and the rainfall intensity for

specific storm duration. The Modified Rational Method adopted from

Hydrological Procedure No.16 published by Drainage and Irrigation

Department (DID) Sarawak was used to generate peak design runoffs

for the respective sub-catchments.

2.3.3.8 Disposal o Construction Wastes

Various types of solid wastes will be generated during the development

and construction stage. These include earth wastes, plant debris, oil

waste, bituminous and earth soils or left over. The general construction

of the project involves the utilisation of construction raw material s,which inevitably result in the generation of wastes such as unused

materials, wrappings and containers. The construction waste

associated with this type of project includes broken bits and pieces of

roofing material, BRC mesh, steel bars, cement spills and concrete

chipping, piping, bricks, hardware, tiles, sanitary ware, glass, plastic

sheets, empty cans and wooden crates. Those wastes shall be

disposed off at approved dumpsites.

2.3.3.9 Tra ic Generation during Construction Stage

The source of workers could be from nearby townships such as Julau

Town, Sibu Town and Bintangor-Sariket areas, and thus transportation

of workers to and from the site may cause additional trips to the local

traffic. However, the existing traffic along Julau Feeder Road is in a

free-flow condition (not congested at all); additional traffic resulted from


12/16



ABC Sdn Bhd 2-12

the construction activities are not expected to cause any adverse

impact to the local traffic.

Most of the machineries and materials for construction will be

transported from Sibu Town. The material transportation trucks will

inevitably generate additional t rips during construction stage, especially

along KJD Road and Jalan Sibu-Bintulu. However, the number of

additional vehicle trips generated by the project would not be significant

and would not elevate the level of service within and beyond project

site even during the peak or off -peak hours.

2.3.3.10 andscaping Works

This involves the final phase of the project development whereby

exposed surfaces shall be turfed; trees are planted at strategic locationalong the internal road network to provide adequate greenery and a

conductive setting for the residents and aesthetic enhancement for the

project.

Spot turfing is a re-vegetation technique where clumps of grass are

planted in spots on a bare earth surface. Spot turfing shall be carried

out on all earth slopes and sensitive areas. Clumps of grass, about 15

cm diameters are placed 1cm apart, compacted and left to grow, with

frequent watering and fertilizing. It is an effective method to control

surface erosion through rapid establishment of dense grass cover over

bare earthwork.

2.3.4 Operation and Maintenance

During the operation phase, the following services must be maintained to

ensure a conducive and healthy working and living environment with the

project site:-

y Solid Waste collection and disposal,

y Sewage treatment,

y Future traffic generation,

y Drainage cleansing,

y Water supply, and

y Electricity supply.


13/16



ABC Sdn Bhd 2-13

Various activities associated with the operational stage of a project are related

to:-

i. Occupation of the newly completed educational buildings and facilities

units by the staff and students,

ii. Generation, Collection and Disposal of Solid Waste,

iii. Sewage Generation and Discharge,iv. Future Traffic Generation, and

v. Maintenance of Utilities, Amenities and Services.

The following description provides a brief outline of the various activities

associated with the operational stage, namely: -

2.3.4.1 Occupation o t e Ne l Completed Project

The proposed SMK Julau No.2 shall be ready for occupation by the

Ministry of Education as soon as the relevant authorities have issued

the Certificate of Fitness (CF). The issuance of the certificate of fitness

is subject to the successful completion of the project. As such, the

developer will be required to comply with all the requirements of the

local authority.

2.3.4.2 Generation, Collection and Disposal o Solid Waste

The generation of solid waste will be one of the most significant

aspects of the occupational stage of the project. Based on an

estimated average waste generation rate of 0.85 kg per person per

day, the daily volume of waste has been calculated to be around 765

kg per day.

The indiscriminate disposal of waste can adversely affect the aesthetic

aspects and surface water qualities. Due to the warm temperatures,

the waste material degenerates very quickly. Thus, improperly

disposed garbage serves as a conducive breeding ground for disease

vectors, which could result in increased incidence of communicable

diseases.

2.3.4.3 Se age Generation and Disc arge

The proposed project is designed to accommodate an estimated

equivalent population of 900 individuals when the proposed SMK Julau

No.2 is fully in operational. Based on the projected design wastewater

flow of 250 litres per person per day, the estimated average sewage


14/16



ABC Sdn Bhd 2-14

flow for the development is projected to be approximately 225 m3

per

day. As such, raw sewage has a great potential to pollute the

environment, thus proper handling is essential before the sludge and

effluent generated by the development can be disposed of without

adversely affecting the environment (details are addressed in C apter

5).

2.3.4.4 Future Tra ic Generation

The academic/teaching staffs and students at the school will inevitably

generate additional trips per peak hour upon completion of the

development. Additional vehicles will ply the local route, namely KJD

Road and Julau Feeder Road. As such, the number of vehicles

generated by the project would not be significant and is not expected to

affect or elevate the level of service at the junction of the project site

even during the peak hours.

2.3.4.5 Maintenance o Utilities, Amenities and Services

Various utilities, amenities and services p rovided within the project

need regular maintenance if they are to continue to serve the end

users efficiently.

2.3.5 Abandonment Stage

Project abandonment may occur at any stage during the development.

Possible causes of project abandonment are the downturn of the national

economy, which may cause problem to government funding and financial

stability, unforeseen technical or management problems and changes in

government policy on the nature of development earmarked for the site.

Thus, relevant activities associated with project abandonment will be

determined by the stage at which it occurs.

However, abandonment during the construction stage or the occupational

stage necessitates the project proponent to consider plans for the removal or

disposal of temporary structures and facilities and the restoration works at the

site. Nevertheless, project abandonment is very unlikely considering the

government commitment to the undertaking of the project.

2.4 PROJECT OPTIONS

As part of the EIA study, various available options for the project developme nt had

been evaluated to ensure that the best possible option would be adopted. The

various possible options associated with the proposed project are outlined in the

following paragraphs.

2.4.1 NO PROJECT Option

A No Project option means that:-

o The on-going planning and design activities would have to cease

and the project abandoned resulting in financial loss to the

government and developer. As such the designated site for the

development project will remain undeveloped until sufficient fund

is obtained to continue the project as planned for the area.

o The potential benefits associated with the proposed development,

which is the development of education to improve and provide

better study environment will not be realised.

2.4.2 Alternative Site

The problems associated with the development of the project at an

alternative site include-

o Difficulty in obtaining strategically located state land to be alienated

to the project proponent for development.

o Problems associated with land acquisition, if private land is

acquired and developed for such purpose.

o Cost of land acquisition may make the project unfeasible or

financially unattractive for the proponent.

o Additional cost to the project proponent in terms of the cost of site

investigation activities, architectural and engineering designs and

so on.


16/16



ABC Sdn Bhd 2-16

2.4.3 Project as Planned

The development of the project as planned is the recommended option

because:-

o The strategic location of the project site, which is in the outskirt of

Julau Town and accessible by good road network.

o It will facilitate the outward expansion of Julau and the development

of the town outskirts by bringing development to the periphery of the

town limit, thus reducing the development pressure and inevitable

traffic build up in the inner town areas.

o The project site is accessible which located along Julau

Feeder Road, one of the main access roads linking Julau Town with

it suburban peripheral, making it an ideal location for an education

place.
