These range from uses for transport infrastructure such as deep interchange stations to building basements for optimising developable space in otherwise constrained sites.

We also specialise in cavern, engineering creating large underground spaces in rock formations for energy and infrastructure projects, underground storage facilities and repositories or even deep underground scientific research facilities.

Our services range from early feasibility, through consenting, ground investigation, detailed design of basements, retaining structures and rock support, through to internal fit out and fire management and evacuation, as well as construction support and site supervision.

Our global expertise is internationally recognised, having authored key standards and design guides which are use worldwide to promote best practice, efficient design and the most robust technical solutions.
