The contract was awarded by Norwegian National Rail Administration, Jernbaneverket. Evacuation tunnels between Larvik and Porsgrunn will also be part of this construction assignment, bringing the total tunnel work to 8.8km.

"This method of procurement, which involves the evaluation of several variables, such as organisation, resources and expertise, is something we welcome and believe benefits all parties," says Hakon Tjomsland, regional director at NCC Construction Norway.
