Background of Study
:
Kawasan
Perindustrian PKNK Bukit Kayu Hitam is located at Bukit Kayu Hitam,
Kedah's main border town on the Malaysia-Thailand Border. The industrial
park is one of the main economic hub in the area, housing important
industries and factories. The industrial park was developed by
Perbadanan Kemajuan Negeri Kedah (PKNK) and is still managed by the
company, which is a business subsidiary of the Kedah State Government.
PKNK received several reports
and complaints from the industrial park occupants and investors in
regards to the flash flood issue in the area. Flooding frequently occurs
since year 2006 and the latest occurred on 07th March 2012. A total
rainfall depth of 168 mm over a 2 hours period has been recorded at
Bukit Kayu Hitam Rainfall Station (MADA’s station) for this event. It
involves the upstream area of the catchment which includes Black Forest
Golf & Country Club and its surrounding area. Among the worst hit areas
include the Asian Composite Manufacturing (ACM) Sdn. Bhd., which suffers
flood damage in the count of millions of ringgit.
A round table discussion held
among PKNK, ACM Sdn. Bhd., and other related government agencies had
identified the cause of flooding. It was concluded that the 3.5m x 3.5m
channel flowing in front of ACM Sdn. Bhd. could not cater to the runoff
coming from various sources around the catchment. One of the sources of
runoff is actually the catchment within the PKNK Industrial Park. Runoff
from upstream development (factories along Jalan PKNK 6 and Jalan 7) was
collected and discharge into the said main drain at a single location.
During peak of event the excessive runoff would form water jets, landing
water directly into ACM Sdn. Bhd. compound rather than into the drain.
Therefore, an improvement of the drainage system is imminent to improve
the situation and prevent further flooding. PKNK proposed to divert the
said catchment so that it discharges directly downstream, by-passing the
said under-capacity channel.
It is on such approaches that
PKNK is inviting Perunding Pinang Sdn Bhd. (hereafter refers to as the
Consultant) to prepare the technical and financial proposal for Cadangan
Menaiktaraf Sistem Saliran Bandar dan Kolam Takungan di Kawasan
Perindustrian PKNK, Bukit Kayu Hitam, Kedah Darul Aman. In response, the
Consultant is submitting this technical and financial proposal after a
few initial site visits to establish the basic understanding of the
Client’s requirements.
Objectives of Study :
The primary goal of this work is
to implement stormwater management system so that the impact of
urbanisation on stormwater environment that affects the livelihood of
urban community could be reduced tremendously through effective
stormwater management facilities. In order to achieve this, the work
shall meet the specific objectives of urban stormwater management are as
follows;
i. To implement stormwater
facilities that give up to date solution for the flooding, drainage and
stormwater management problems in the existing built-up areas in order
to reduce the adverse effects of flooding on people and property and to
protect the existing and proposed development by implementation of an
integrated stormwater management by providing an appropriate level of
affordable flood protection to community expectations.
ii. To upgrade the effectiveness
of the existing stormwater infrastructure network within the project
area in a way that meets the needs of the community and where possible,
by providing and maintaining stormwater management infrastructure at an
acceptable quality of service, taking into account environmental effects
and public expectations.
iii. To provide control
structures against excessive sediment and floatable rubbish in
watercourses to acceptable levels by managing the catchment activities
using at source control measures to prevent any acceleration of the rate
of erosion from generated from developed areas, on land and in stream
channels.
Scope of Work :
Pursuant to the objectives as
outlined above, the scope of work is drawn to describe the structured
mechanism on how the project should be executed, as well as providing
details on the issues and the associated areas to be addressed. The
scope of work covers various components with activities ranging from
data collection, identification of issues, planning and preparation of
supporting documents. The scope of works shall include but not be
confined to the following:
i. Hydrological and Hydraulic
Analysis.
ii. Detailed Planning and
Design.
iii. Channel/Pond Bank and Slope
Protection Works.
iv. Working Drawings and Tender
Documents.
v. Tender Administration.
vi. Construction Supervision,
Contract Administration and Commissioning of Completed Works.
vii. Drainage/ Pond/ River
Reserve and Land Acquisition Plans.
viii. Operation and Maintenance
Manual.
ix. Use of Local Materials.
x. Design Report.
