Roads & Highways

Civil structures for roads and highways: retaining walls, culverts, noise barriers, cut-and-cover structures and foundations for highway equipment.

Not the alignment but the structures along it: everything that has to be analysed and reinforced.

What we take on

  • Retaining walls, cantilever walls and reinforced soil structures
  • Culverts, cut-and-cover structures and underpasses
  • Foundations for noise barriers, sign gantries and portal structures
  • Temporary works and excavations within the highway

The interface it turns on

The highway design fixes the alignment and the cross-section, the ground decides the foundations, and the construction sequence has to allow the traffic management to work. We provide reliable structural dimensions early, so the highway designer is not building on assumptions.

Existing structures

With existing retaining structures the work starts with the survey: what is there, how is it founded, and does any record exist. Only then does a repair or replacement strategy follow.
