Halcrow and US consultant KBR have been awarded the programme management services contract on the 1.3bn project to build the world’s longest causeway between Qatar and Bahrain.
The two companies beat rivals including Mott MacDonald to oversee the contracting consortium on behalf of the client, the Qatar-Bahrain Causeway Foundation.
The construction contract was awarded in May to a consortium led by Qatari Diar and France’s Vinci Construction Grand Projets. The group also includes Germany’s Hochtief, Athens-based Consolidated Contractors Company, Belgium’s Dredging International, and the local Middle East Dredging Company.
Denmark’s Cowi is working as the design consultant.
Named the Friendship Causeway, the project will link Ras Ashiraj on the west coast of Qatar to the village of Askar on the east coast of Bahrain.
The 40km project will comprise 18km of embankments where the sea is shallow and 22km of viaducts and bridges over deep water, including two 400m cable-stayed bridges over shipping channels.
