The breakwater and the tunnel building contracts are to be executed in the UK and in Sweden.
The breakwater will consist of 23 stone groynes with sand fill to create beaches in between. Boskalis will execute the project through the VBA JV Ltd (a consortium of Volker Stevin, Boskalis Westminster and Atkins).
Work is scheduled to begin this summer and will be complete late 2015. Two medium-sized trailing suction hopper dredgers will be deployed on this project, with all the stone work being performed by dry equipment.
In Sweden, a joint venture of Boskalis and Züblin Scandinavia AB has won a contract from Trafikverket Göteborg for the design and construction of the Marieholm Tunnel and construction of quay walls in the city of Gothenburg.
This new traffic tunnel under the Göta Älv River will connect the urban districts of Marieholm and Tingstad in Gothenburg. The Design & Construct contract runs until end-2020.
For the realization of this project Boskalis will dredge a trench with a depth of around 20 meters into which the tunnel will be submerged, install the sand beneath and alongside the submerged tunnel and install a layer of rubble to protect the tunnel roof.
