Implenia wins large and complex tunnelling project in Norway – E03 Boknafjord tunnel

The Norwegian Public Roads Administration assigns the E03 Boknafjord tunnel project to a joint venture (JV) consisting of Implenia (80%) and Stangeland Maskin (20%). The total contract volume amounts to around CHF 375 million (NOK 4 billion), Implenia’s share is approximately CHF 300 million.
 
The project consists of an 8.6 km long tunnel with two tubes and a 125 m long stretch of road in the day zone. It is linked to the E39 Rogfast project, which is one of Norway’s biggest infrastructure projects, building the world’s longest and deepest underwater tunnel. The E03 Boknafjord tunnel project starts this month already and is scheduled to be completed in 2030.

Implenia is in charge of the excavation and tunnelling work as well as of the interior construction of the tunnel. 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.
 
Implenia convinced with the best total package and smart solutions
