This contract package forms part of the overall development of project for the Design, Construction, Completion and Commissioning of Integrated Customs, Immigration and Quarantine Complex in Johor Bahru, Johor, which was generally referred to as Gerbang Selatan Bersepadu Project.

There are two (2) nos. 1600mm diameter treated water pipelines at Jalan Jim Quee and two (2) nos. 1600mm diameter treated water pipelines and one (1) no. 1800mm diameter raw water pipeline at Tanjung Puteri which need to be permanently relocated to facilitate the construction of new bridge, road and monsoon drain, associated with the Gerbang Selatan Bersepadu Project.

These pipelines are presently conveying treated water and raw water from Johore State to Singapore and are owned by the Public Utility Board (PUB) of Singapore.

Briefly, the scope of works for this contract package comprises the following major components:

  1. Supply and deliver to the site approximately 1800m long of 1600mm diameter and 210m long of 1800mm diameter mild steel pipes and associated specials, fittings and joint materials.
  2. Excavate, lay and joint 1600mm and 1800mm diameter mild steel pipeworks including filling and forming of embankment/platform wherever required.
  3. Expose existing pipelines at the points of inter-connection (10 locations), make preparation for cutting of existing pipes for jointing to the proposed new pipelines.
  4. Pressure testing, sterilisation, flushing and commissioning of the proposed new pipelines.
  5. Retrieve existing pipes when required.
In view of the anticipated difficulties in the laying of the proposed new pipelines in down town area of Johore Bahru and sensitivity of water supply disruption to Singapore during inter-connection works, the Turkey Contractor, Gerbang Perdana Sdn Bhd only invited Class ‘A’ contractors experienced in the laying of big diameter pipelines to participate in the tender for this contract package. Casavest (M) Sdn Bhd being one of the invited tenderers was awarded the contract due to the Company’s experience, track records and commercial competitiveness. Asia Baru Construction Sdn. Bhd. was appointed as sub-contractor by Casavest to carry out the pipelaying and associated works.
