Abu Dhabi government-owned investment firm Mubadala Development Company has invited contractors to prequalify for the contract to build the Four Seasons hotel on Sowwah Island.

The planned five-star hotel will be a 144-metre high tower with a gross floor area of about 100,000 square metres.

The 200-room hotel will contain restaurants, a swimming pool, spa, gym and conference centre. The development will also include 124 apartments and a 6,000 sq m retail area. In addition, the hotel will have 16,000 sq m of car parking space.

The estimated duration of the contract is 24 months, scheduled to begin when enabling works are completed in the fourth quarter of 2010.

Mubadala is also responsible for the development of the rest of Sowwah Island, located between Reem Island and the port area of Abu Dhabi Island.

In January, it awarded the local/Lebanese Arabian Construction Company (ACC) an estimated AED800m ($218m) contract to build the Rosewood Abu Dhabi Hotel on Sowwah Island.

The project covers the construction of a five-star hotel with 189 rooms and 139 serviced apartments, a retail area, basement parking and other facilities including a swimming pool, health club and spa. The total built-up area is about 100,000 sq m.

In March, it awarded the joint venture of the local/Belgian Six Construct Abu Dhabi and South Korea’s Samsung Corporation an estimated AED4.7bn contract to build Cleveland Clinic, which will also be on Sowwah Island.

When complete, Cleveland Clinic will be a 364-bed, 220,000-square-metre hospital with parking spaces for 3,200 cars.

Work is already under way on other parts of the island. Oger Abu Dhabi has been building the estimated AED4bn Sowwah Square development since mid-2007, and the local Al-Naboodah Construction Group has been working on the island’s infrastructure since mid-2008 (MEED 8:3:10).
