Scheme to transport wastewater from island to Al-Wathba treatment plants
Abu Dhabi Sewerage Services Company (ADSSC) has received bids from four groups for the estimated AED2bn ($572m) contract to build a pumping station as part of its strategic tunnels enhancement programme.
The bids were submitted on 7 January.
The bidders are Kuwait’s Kharafi National with Lindenberg-Emirates and the local/Lebanese Arabian Construction Company (ACC); Germany’s Ed Zueblin; Brazil’s Odebrecht; and the local/Australian Al-Habtoor Leighton Group (MEED 7:12:09).
ADSSC has already awarded one construction contract for the tunnels programme, and has selected preferred bidders for two more contracts.
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 also chose 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.
The programme will transport sewage from Abu Dhabi Island to treatment plants at Al-Wathba.
US-based CH2M Hill is the programme manager for the scheme.
