Flood Mitigations Works, Kuching (Phase 1), Sarawak
The Department of Irrigation and Drainage commissioned the contract for the construction of the first two kilometers of the Flood Bypass Channel at the downstream end of the Sarawak River. The turnkey contractor for the project was a joint venture between Naim Cendera Sdn Bhd and Ambang Project Management Sdn Bhd.
Phase 1 Stage 1 included the excavation of two kilometers of the proposed eight kilometers flood bypass channel, construction of disposal site for dredged materials and the access roads. Excavation for the channel was mainly carried out using cutter suction dredgers by pumping the dredged material to sedimentation ponds before the water was discharged back to the river. An environmental monitoring programme was also undertaken to ensure that discharged water met the standards allowed by the authorities.
The site was handed over to the Naim Cendera Sdn Bhd and Ambang Project Management JV in September 2008 whereupon the contractor immediately mobilized personnel, machinery and resources to commence site clearing, earthworks and associated works for the channel and the disposal site. The project was successfully completed on schedule on 31st March 2010.
