The hotel will be built on Al Maryah Island in Abu Dhabi's new central business district. Construction of the five-star hotel, which will be 144m high and have a floor area of 100,000m2, will start straightaway and is scheduled for completion by the end of 2015.
Carillion chief executive Richard Howson said: ''We are delighted to have been selected for this prestigious contract, which reflects our reputation for delivering high-quality projects. We look forward to working with Mubadala to design and build this state-of-the-art hotel and to building on the strong, long-term relationship we have with Mubadala in Abu Dhabi."
The contract was classified as a probable order in Carillion's interim management statement last month.
Al Maryah Island (formerly Sowwah Island) is a 114ha mixed-use development, designated by the emirate's Urban Planning Council to be the capital's central business district. The island is being developed in three phases, starting with Sowwah Square, which will provide 450,000m2 of office, hotel and retail space. The island is at a midpoint between Abu Dhabi's existing downtown district, upcoming developments at Al Reem Island and Mina Zayed, and the new cultural district on Saadiyat Island.
Al Futtaim Carillion is currently delivering two other contracts in Abu Dhabi for Mubadala Development Company, namely the £600m contract to construct New York University Abu Dhabi on Saadiyat Island and a £20m enabling-works contract for a military maintenance repair overhaul centre at Al Ain.
