Tunnels and underground facilities

Norconsult has a large professional group consisting of more than 30 employees with extensive experience and cutting-edge expertise in the design of tunnel installations. The experience ranges from simple tunnel projects to the world's longest and deepest subsea road tunnels at Ryfast and Rogfast, as well as large railway projects such as the Ringerriksbanen. We have expertise in all subject areas within a tunnel project, and often work in collaboration with several other professional groups. The tunnel group is involved in all planning phases from early phase studies to construction planning and follow-up. We work closely with other infrastructure groups of the company and have a vital role in some of Norway's largest interdisciplinary road and rail projects. This includes both subsea tunnels as well as large and small road and railway tunnel projects within infrastructure facilities. All planning for new assignments is now performed in 3D / BIM-design.
