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