PROJECTS > New Gadek Treatment Works and Bulk Transfer - Package B

Project Background
The existing 4.5 Mld Gadek Treatment Works was built some 40 years ago. It was in a dilapidated and obsolete state and refurbishment was uneconomical. A decision was made by Perbadanan Air Melaka (PAM) to demolish this existing Treatment Works and to construct a modern one in the same locations with nominal capacity of 55 Mld to cater for the increasing water demand. An open tender was called by PAM and Asia Baru Construction Sdn. Bhd. was successful in its bid and was awarded the contract on a fixed non-escalating lump sum price to design, construct, test and commission the treatment works for a construction period of 20 months and henceforth operate and maintain the Works during the 12 months Defects Liability Period.

Briefly, the scope of work for the project comprised the following major components:

> Demolition and disposal of the existing treatment works.

> Site formation works, turfing, access roads, drainage system, security fencing and gates.

> Intake and raw water pumping station including river protection works.

> Raw water pumping main.

> Process unit comprising aerator, mixing chambers, flocculation tanks, settling tanks including clarifier control building, filter tanks and filter control building and lastly, contact and clear water tank.

> Administration building.

> Chemical and chlorination building.

> Waste water handling unit comprising washwater settling tanks and sludge pumphouse, sludge thickening tanks and sludge balancing tank.

> Sludge lagoons inclusive of inlet, outlet, drainage and protection works.

> Treated water pumping station.

> Other ancillary buildings like TNB substation, consumer switchroom, guard house, store and weigh bridge.

> 750mm Fid. MS pumping main from the Treatment Works to the new Bkt. Tiga balancing reservoir and connection to the existing reservoir.

> 18.0 ML balancing reservoir at Bkt. Tiga inclusive of switchroom, site formation works, turfing, access road, drainage work, gate & fencing.

> Complete M&E works for the Water Treatment Plant comprising pumping plant, electrical plant, process and chemical plant, instrumentation and SCADA system, building services, sewerage disposal system, service water system, tools, tests instruments and spare parts for all items of the Plant.
Project Information
Client / Owner: Perbadanan Air Melaka (PAM)
Consultant: SMHB Sdn. Bhd.
Main Contractor: Asia Baru Construction Sdn. Bhd.
Sub-Contractor: N/A
Date of Commencement: 1st August 2001
Date of Completion: 30th June 2003
Project Methodology
The project site was rather congested considering the number of buildings / structures and the relatively large sludge lagoons (2 nos.) to accommodate a 55 Mld Water Treatment Plant. This calls for logistics skills and careful project planning and execution of works to avoid unnecessary constraints due to the limited space and hence maneuverability between structures and temporary storage during the construction stage.

With a dedicated project implementation team tasked to liaise and coordinate closely with all the various trades involved at site and with the cooperation of all parties concerned, the execution of the works for both civil and M&E were accomplished without many hitches.

Given the shortage of workers as generally experienced by the construction industry from July 2002 onwards, Asia Baru Construction Sdn. Bhd. together with its M&E Sub-contractors came out relatively unscathed. After completion of installation works and upon landing TNB power supply which was slightly delayed, series of site tests were carried out for all the plants and equipment in the presence of Consultant's representatives. This was followed by pump performance test, setting to work and commissioning of the whole treatment plant for 7 days continuously.

The whole project was completed within the approved extended contract period. Hence, adding another milestone and achievement to Asia Baru's already impressive track record of successfully completing another water supply project as complicated as a water treatment plant. This time as a Main Contractor for both the Civil and M&E Works.

This was quite a formidable achievement by Asia Baru Construction Sdn. Bhd., considering that the contract was won under a very competitive environment of an open tender. More so under the challenging circumstances of labour shortage and rising construction costs during the implementation stage.
