B&K will start construction of the clam-shaped pool roof next month.
The build of the Subtropical Swimming Paradise is on track, with all the Glulam wooden beams that support the roof in place and basement works almost complete.
Construction of the roof will begin in July with a completion date for the entire structure of January 2014.
B&K’s contract is worth £93m and also includes work on restaurants, spa, a 75-bedroom hotel, sports hall, conference spaces, supermarket and other associated buildings.
ISG has won a separate £61m contract to build 624 lodges at the site while Birse has a £26m roads and technical infrastructure deal.
