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
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.
