Building tunnels is a high risk business that calls for special experience. COWI’s tunnel consultancy services draw on decades of underground experience around the world.

Whether underwater, underground or both, tunnels and other subsurface structures have a wide variety of uses. During its history COWI has been involved in the construction of all manner of tunnels around the world, and in all types of soil.

COWI’s services cover the entire lifecycle of a tunnel, from feasibility studies to the operational phase and finally rehabilitation or decommissioning. We provide customers all levels of support, from professional advice on a specific problem to comprehensive planning and total engineering design and implementation of large-scale projects.

Half century of expertise

Our longstanding experience with all phases of tunnel and infrastructure construction ensures that the design meets the needs of the individual project. Over the past half century, we have developed a particular in-house knowledge that has earned us an international reputation as a world leader when it comes to tunnelling. 

Full-service consultancyBuilding underground is a complex and detailed process that normally requires affiliated services such as ventilation, risk management and service life design. But since tunnels seldom stand alone, COWI can also deliver integrated rail, road, bridge and marine engineering services.
