Abu Dhabi delays pumping station tender to 2010

08 December 2009

Project is part of $572m strategic tunnels enhancement programme

Abu Dhabi Sewerage Services Company (ADSSC) has extended the bid deadline for an estimated AED2bn ($572m) contract to build a pumping station as part of its strategic tunnels enhancement programme to 5 January. The previous deadline was 7 December.

The utility first asked contractors to submit bids in early September.

The prequalifiers include Bouygues, Vinci Construction Grand Projets, both of France, Kuwait’s Kharafi National with Lindenberg-Emirates and the local/Lebanese Arabian Construction Company (ACC), Brazil’s Odebrecht, and the local/Australian Al-Habtoor Leighton Group (MEED 22:11:09).

ADSSC has already awarded one construction contract for the tunnels programme, and has selected preferred bidders for two further contracts. The programme will transport sewage from Abu Dhabi Island to treatment plants at Al-Wathba (MEED 13:9:09).

Italy’s Impregilo won the AED891m contract to build the middle section of the 40-kilometre-long tunnel from Mussafah to Mafraq in the first week of September.

ADSSC has also chosen Impregilo as the preferred bidder for the second contract estimated at AED785m. It involves the construction of a 15.6km, 5-metre-diameter tunnel between Mafraq and Al-Wathba.

South Korea’s Samsung Corporation is the preferred bidder for the third contract, estimated to be worth AED1.1bn, to dig the 16.1km, 4-metre-diameter tunnel from Abu Dhabi Island to the Mussafah area.

US-based CH2M Hill is the programme manager for the entire scheme.
