We provide specialist design services at all stages of project delivery, from concept through to detailed design for permanent and temporary works. Working with our in-house research and development department, we can thoroughly investigate innovative concepts prior to implementation.

Permanent Works Design

Our chartered civil and structural engineers have extensive experience across a breadth of tunnelling and infrastructure schemes. With specialists in 2D and 3D finite element analysis, we are industry leaders in the effects of soil-structure interaction, allied with capabilities in addressing foundation and subterranean designs through in-house geotechnical engineers and engineering geologists.

Our in-house experience includes:

  • Shaft design, including design of small and large scale shaft and tunnel linings
  • Sprayed concrete tunnels
  • Cross passages and tunnel junctions
  • Escalator and station tunnels
  • Water-retaining structures
  • Multi-storey steel frames
  • Large scale pump and motor foundations
  • Sea outfalls and more.

Temporary Works Design

We undertake all aspects of temporary works designs, from the smallest detail to complex, multi-stage bespoke solutions.

We offer review services for subcontractor and proprietary suppliers’ designs, plus evaluation of temporary works proposals.
