The local/Belgian Six Construct Abu Dhabi has won the estimated AED1.8bn ($490m) contract to build a new headquarters for state-owned Abu Dhabi National Oil Company (Adnoc).

The new 342-metre tall building will be located adjacent to the current Adnoc headquarters, at the intersection of Corniche road and Bainunah street in Abu Dhabi.

The scheme includes an office tower, podium and atrium, basement parking areas, a separate underground car park, and a tunnel connecting the office tower with the car park. The total built-up area will be about 190,000 square metres.

The other companies that submitted bids for the contract include the local/Australian Al-Habtoor Leighton Group; the local Arabtec Construction; South Korea’s Hyundai Engineering & Construction; Australia’s Multiplex; Turkey’s Nurol; and Germany’s Ed Zueblin (MEED 17:2:10).

Abu Dhabi’s Arabian Foundations was the contractor for the enabling works package. The architect is US-based Hok. The US’ Hill International is the project manager.

At least two other major headquarters buildings are built in Abu Dhabi. In December last year, sovereign wealth fund Abu Dhabi Investment Council (Adic) formally awarded the local/UK Al-Futtaim Carillion the estimated AED900m contract to build its new offices.

In May last year, International Petroleum Investment Company (Ipic) awarded an estimated AED900m contract to the local Commodore Contracting Company for its headquarters.
