Masdar, the £13bn UAE project to create the greenest city on earth, has invited five UK organisations to tender for the contract to design its sustainability standard

They are Aecom, Arup, BRE, Hyder and WSP. Cyril Sweett is advising BRE on the cost element of its bid.

The standard will set out sustainability targets for the project. Abu Dhabi Future Energy Company, the developer of the 5.5 million m2 city, invited bids at the beginning of June and it is understood shortlisting is imminent.

A source close to the bidders said the standard was intended to go beyond anything done before. He said Masdar would be likely to aim to be carbon positive, water neutral and waste neutral.
