Specialists in all forms of tunnel design and construction in soft ground and hard rock by TBM, drill and blast, immersed tunnel and jacked box techniques. We have planned and designed numerous road, rail, metro, water and service tunnels in all corners of the earth including the SMART road/water tunnel in Malaysia, Boston Central Artery in the USA, Lesotho Highlands Water Project in Africa, the Channel Tunnel between the UK and France, and much of the London Underground metro system.
