The Norwegian Public Roads Administration has awarded the E03 Boknafjord tunnel project contract to a joint venture (JV) consisting of Implenia (80%) and Stangeland Maskin (20%). The total contract volume amounts to around US$404M.
The project consists of an 8.6km long tunnel with twin tubes and a 125m long stretch of road. The project is linked to the country’s E39 Rogfast project, which is one of Norway’s biggest infrastructure projects, and includes building the world’s longest and deepest underwater tunnel. The E03 Boknafjord tunnel project will start this month and is scheduled for completion in 2030.
Implenia will take charge of the excavation and tunnelling works. Stangeland Maskin will be responsible for the transport of the excavated material as well as for the construction of the road including the drainage works.
“We are excited to win such a major and prestigious project together with our JV partner Stangeland Maskin. The project E03 Boknafjord tunnel is a large and complex infrastructure project in line with our strategy, where we can contribute our many years of experience and proven expertise in tunnel construction and related civil engineering disciplines,” says Erwin Scherer, Global Head Tunnelling of Implenia.
