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.
