Abu Dhabi Airports Company (Adac) has invited shortlisted contractors to resubmit bids in September for the estimated AED1bn ($272m) contract to build the airside areas for the midfield terminal building at Abu Dhabi International airport.

Contractors submitted bid for a remeasurable contract in early June. The contract has now been changed to a lump-sum contract and about six of the original bidders have been asked to submit fresh bids.

The contract will support the 65 contact gates and up to 19 remote stands that the proposed terminal building will have. The construction work involves infrastructure and civils works around the midfield complex, including 300,000 square metres of pavement concrete, 600,000 sq m of flexible pavement with taxiway connections to the existing and future taxiway systems, and the installation of utilities such as power, stormwater drainage and a jet fuel system.

In late June, the consortium of Turkey’s TAV, Athens-based Consolidated Contractors Company (CCC) and the local Arabtec Construction has been awarded the estimated AED10.55bn ($2.87bn) contract to build the midfield terminal building at Abu Dhabi International airport.

The midfield terminal will be built between the two existing runways at Abu Dhabi International airport. The total built-up area will be 630,000 sq m and it will also include a multi-storey car park. The terminal will include 27,000 sq m of retail and food and beverage outlets. It will also comprise 65 contact gates that will be able to accommodate the Airbus A380 aircraft.

The consortium for the terminal building completed a AED4bn ($1.1bn) contractor financing deal for the construction work in early August. All the funds are in place and the terms agreed, although a final signing to mark the conclusion of the contract is not expected to occur until early September, according to sources close to the deal.
