Skanska starts on Amsterdam metro project

Cementation Foundations Skan-ska has scooped a £26m deal that marks the start of the £625m North-South Metro line project in Amsterdam, Holland.
In joint venture with local firm Franki Geotechnics, Skanska will construct diaphragm wall foundations at three city centre sites.
The deal involves 70,000m2 of retaining wall spanning 1.7km and to a thickness of 1.2m and depth of 45m. Skanska will work under a form of partnering incorporating unit rates and target costs, with the client, the City of Amsterdam, taking responsibility for risk.
The work is complicated by the narrow streets and the city's canal network with the water table just 1m below ground.
