Tunnelling excellence

Providing industry-leading design and construction tunnelling expertise complemented by our precast manufacturing service

  • Delivering specialist tunnelling projects combined with an in-house professional underground design service
  • Pioneering innovative ways of working and using value engineering to help our customers achieve their goals

As one of the UK’s leading tunnelling businesses we offer customers the all-round capability to deliver projects of all sizes in every type of ground condition.

Our customers receive a bespoke service through our vastly experienced tunnelling team, a design capability through our team at Morgan Sindall Engineering Solutions, and the provision of quality assured concrete tunnel linings manufactured in our own purpose-built factory. Our team has helped to pioneer numerous innovations within the UK tunnelling industry in the past 20 years, including waterproof sprayable membranes, the ‘tunnel beamer’ and the ‘lasershell’ method of tunnel construction. All of these developments are driven by a strong desire to improve the safety and quality of underground works. This approach to innovation allows us greater flexibility to tailor projects individually to customer requirements, using custom-built rather than ‘off the shelf’ solutions.

Our tunnelling projects include the £422 million Lee Tunnel for Thames Water (as part of the MVB joint venture), which stretches for seven kilometres 90 metres below London and features some of the deepest shafts in Europe. We also delivered the C510 Whitechapel and Liverpool Street Station tunnels contract for Crossrail, where we constructed all station tunnels, as part of the BBMV joint venture.

In addition to the above capabilities, we offer feasibility and option studies, buildability advice, risk analysis and production of cost estimates.
