AECOM offers a comprehensive tunnelling and underground structures consultancy service to clients seeking cost-effective, buildable, and state-of-the-art tunnel projects. Our team has proven global design experience across a wide range of tunnels in challenging geological conditions. We have successfully delivered sustainable projects in some of the world鈥檚 most congested cities, working collaboratively across multidisciplinary teams.
Our current projects include London Power Tunnels, Elephant & Castle Station upgrade, Pumped Hydro Storage schemes, Snowdonia Power Tunnels, and Thames Tideway Sewer. We also work for Network Rail, Water Authorities, and the UK鈥檚 Geological Disposal Facility for radioactive waste.
For example, on London Power Tunnels 2, AECOM was engaged to carry out the detailed design of eight deep shafts (around 15m diameter and 50m deep) in congested areas of London, connected by a 33km tunnel. The shafts were constructed in challenging ground conditions using techniques including secant piling, sprayed concrete linings, and segmental linings. Our engineers worked as part of a large international team to deliver this high-profile project and continue to pursue similar schemes.
