Construction of the Qatar-Bahrain causeway, at 40 km said to be the world’s longest bridge, is due to start next year.
This will be a design-build operation in the hands of a consortium of construction companies led by Vinci Construction Grands Projets. The Middle East Dredging company Medco, a subsidiary of the Vinci Group company CFE, will carry out the dredging work required to build the motorway connection between Qatar and Bahrain.
The value of the contract recently signed between Vinci and Qatari Diar (causeway foundation) is put at US$3 billion.
The project is a joint venture between Vinci Construction Grands Projets and QDVC, a Qatari subsidiary owned 51 per cent by Qatari Diar and 49 per cent by Vinci and its contracting partners.
Other companies in the consortium are Hochtief and Athens based Consolidated Contractors International. The Danish engineering consultant COWI, which conducted pre-contract studies of the causeway, is working as design consultant for the consortium.
A further contract is expected to be awarded shortly for the client representative and program management role. The successful bidder reporting directly to Qatari Diar will be responsible to the client for managing construction of the project.
The causeway calls for design and construction of a dual carriageway motorway connection between the two island states. It will run over a total of 18 km of embankments where the sea is shallow and 22 km of viaducts and bridges over deep water. These will include two 400m cable stayed bridges over shipping channels.
Known as the Friendship Bridge, the causeway will reduce the journey time between Qatar and Bahrain to about 30 minutes compared with five hours by road at present. Work is to start after nine months of further studies and the structure itself is due for completion in 51 months.
