A contract to build an immersed tube tunnel in Stockholm has been awarded to a joint venture of Ed Züblin and local firm E Pihl & Son by Banverket, the Swedish Rail Administration.
The 370m long immersed tube will be executed on the rail project on a design and build basis by the JV for approximately US$200M. The tube will be in the southern section of the link in the Fjarden river between Riddarholmen and Sodermalm.
As part of Banverket’s 6km long City Line (or “Citybanan”) double track link which will be built entirely in tunnel, the immersed tube will be a key element in de-bottlenecking the rail capacity in the capital.
The project has been under development for more than two decades, has a total budget of US$2.5bn, and is due to come into operation in 2017. Two new stations – Station City and Odenplan with extensive excavation for a network of passages plus drill and blast drives for the twin bore running tunnels are key features in the project. Züblin and Oden have been opening an access tunnel. Consultants include WSP Group.
