Highways Structures Engineering

Much of the UK's highway infrastructure is ageing and needs repair, protection and strengthening to stay safe and in service. We work on bridges, gantries and other structures across the Strategic Road Network and local authority networks, delivering steelwork, coatings, access and structural repairs with our own teams.

Tier 1 contractor for local authorities

For local and regional highway authorities, we work as Tier 1 principal contractor, managing schemes from design and access planning through to handover. Because our structures, coatings, access and fabrication teams are in-house, authorities deal with one contractor accountable for safety, quality and programme, with fewer subcontract interfaces to manage. 

Tier 2 partner on National Highways SDF2

We operate as a Tier 2 supply chain partner under National Highways' Scheme Delivery Framework 2 (SDF2), the programme for renewing, maintaining and enhancing England's motorways and major A roads. We work alongside Tier 1 contractors to deliver specialist structures packages, bringing self-delivered capability that reduces interfaces and keeps programmes under control.

Our highways services

  • Bridge repairs and refurbishment: repair and refurbishment of steel and concrete highway structures
  • Structural strengthening and steelwork repairs: repair strategies designed to meet minimum viable product (MVP) requirements, keeping structures safe and in service at the lowest whole-life cost
  • Surface preparation and protective coatings: blasting and high-performance coating systems that extend asset life
  • Gantries, parapets and fencing: repairs and corrosion protection to keep roadside structures fit for purpose
  • Access and encapsulation: scaffolding, rope access and encapsulation designed around traffic management and lane closures
  • New footbridges: steel gantries, footbridges and bridges designed and fabricated at our Blackburn facility

Minimising disruption to road users

We plan access, encapsulation and working methods around the traffic management in place, so that more work is done within each closure and lanes reopen on time. We work with the client's engineers to agree shared targets for safety, programme and cost from the start.
