Abu Dhabi Future Energy Company (Masdar) is preparing to reissue tender documents for the contract to build its headquarters at the Masdar City development in Abu Dhabi.

The contract was first tendered in 2008 when four companies submitted bids. In January 2009 Masdar shortlisted US-based Contrack International and Germany’s Ed Zueblin for the contract, saying that an award was expected during the first quarter of that year (MEED 22:1:10)

The tender was cancelled earlier this year.

Chicago-based Adrian Smith & Gordon Gill Architecture has designed the building as the world’s first large-scale “positive energy” building, generating more energy than it consumes.

Louis Berger Group is the project manager, Environmental Systems Design is the mechanical, electrical and plumbing (MEP) engineer, and the structural engineer is Thornton Tomasetti, all from the US.

Masdar is also close to awarding the contract to build the next phase, known as 1b, of its Masdar Institute of Science & Technology (MIST).

That contract, like the headquarters, was also retendered.

The Al-Ahmadiah/Hip Hing joint venture is already working on phase 1a of the MIST project.

The 6.5-square-kilometre Masdar City, designed by Foster & Partners, is set to be completed by 2016. It will eventually grow to accommodate 1,500 businesses and 50,000 residents.
