COWI UK Limited is recognised as a leader in tunnel design and the development of underground space.

Every project stage

Our services cover the entire lifecycle of a tunnel, from feasibility studies, through design, construction support, to the operational phase and finally refurbishment.

Every tunnel type

Our experience covers the full range of bored tunnels from micro-tunnelling to large diameter TBMs in rock, soil and mixed conditions. We have knowledge of complex tunnel layouts in soft ground, using SCL sequential excavation and hard rock tunnelling including caverns, using drill and blast techniques. We also design support for traditional techniques such as hand mining. Together with COWI, COWI UK is experienced in the design of cut and cover tunnels and COWI is one of the world leaders in the design of Immersed Tube Tunnels.

Every sector

Staff have been involved in the design of tunnels for rail, road and power across the globe. We provide customers with all levels of support, from professional advice on a specific problem to the comprehensive planning and total engineering design and implementation of every scale of project.
