Background of Study:

Bandar Bukit Kayu Hitam is Kedah's main border town on the Malaysia-Thailand Border. It is managed under the jurisdiction of Majlis Daerah Kubang Pasu (MDKP). The Department of Irrigation and Drainage, Kedah (DID Kedah) had receives many reports and complaints from local residents and industrial investors due to the flash flood problems. Flooding frequently occurs since year 2006 and the latest occurred on 7th 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.

DID Kedah suspected that the overflow from the detention pond located inside golf club cannot cater to the peak flow from the rainfall event, hence cause flooding further downstream. As a consequence, this area is rather flood prone especially during heavy downpour. In order to solve the flooding issue, DID Kedah requires the service of an established consultant who is familiar with stormwater design in Malaysia using the Urban Stormwater Management Manual for Malaysia (MSMA) by the Department of Irrigation and Drainage (DID) Malaysia, to conduct feasibility study and subsequently produce the mitigation plan to overcome the problem.

It is on such approaches that The Department of Irrigation and Drainage, Kedah (DID Kedah) is inviting Perunding Pinang Sdn. Bhd. (hereafter refers to as the consultant) to prepare Kajian Kejuruteraan dan Rekabentuk Terperinci Bagi Rancangan Tebatan Banjir, Bukit Kayu Hitam, Kedah Darul Aman. This four month study was awarded on 1st October 2012.

 

Objectives of Study:

The primary goal of this work is to implement stormwater management system so that the impact of urbanization on stormwater environment that affects the livelihood of urban community could be reduced tremendously through eco-friendly 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.

iv. To construct stormwater collection and conveyance systems from a catchment to its receiving waters that curtail minimal impact to the surrounding areas by managing and improving the quality of stormwater runoff from urbanized catchment and its pollution loads in order to reduce the adverse effects of non-point source contamination on the receiving water environment and by eliminate point source pollutions discharges where possible to stormwater systems and receiving water in order to reduce the adverse effects of point-source contamination.

 

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. Engineering Surveys and Geotechnical Investigation

ii. Hydrological and Hydraulic Analysis

iii. Detailed Planning and Design

iv. Channel/Pond Bank and Slope Protection Works

v. Working Drawings and Tender Documents

vi. Drainage/Pond/River Reserve and Land Acquisition Plans

vii. Operation and Maintenance Manual

viii. Use of Local Materials

ix. Training for JPS Staff
