Retention and soil improvement of the Drammen cut & cover and tunnel


In Norway TREVI S.p.A. has been awarded by Veidekke Entreprenør, the largest Norwegian construction company, the retention and soil improvement of the Drammen cut & cover and tunnel, which is part of the Vestfoldbanen section from Drammen to Kobbervikdalen.

The project is complex, crossing a densely populated residential area with heavy traffic and several interferences on steep surfaces. It will provide a new 10 km double-track railway, 7 km of which will be in tunnel.

Bane NOR, the Norwegian state-owned company responsible for the railway infrastructure, is planning 270 km of new double-track from Lillehammer to Skien and the project is an important and challenging part of this development.
