Specialist Engineering for Highways Infrastructure
Supporting bridges, highways and civil structures with temporary works, structural jacking, bearing and expansion joint replacement, inspection and maintenance — delivered safely across the UK and Ireland.
Engineering support for bridges and highway structures
Highway and bridge structures carry enormous loads and must stay safe and serviceable while traffic keeps moving. 3RS Engineering delivers complex highways works — from bearing and expansion joint replacement to temporary works, structural jacking and heavy lifting — often within tight possessions and live carriageway constraints.
Our combined civil, structural and mechanical capability means a single accountable team can take a scheme from early engineering input and methodology through to manufacture, installation, inspection and commissioning — reducing risk and keeping critical infrastructure open.
Practical engineering expertise for highway structures
We provide end-to-end support across bridge and highways projects, from early involvement and technical planning through to manufacture, installation, inspection and commissioning.
Early Contractor Involvement
We work with clients, designers and principal contractors from the early stages of a scheme to develop safe, buildable and cost-effective engineering solutions — covering methodology, temporary works, programme and value engineering before works begin on a live highway.
Typical support includes
Site Installation & Maintenance
Our experienced site teams deliver installation, replacement and maintenance works on live highway and bridge structures, with a strong focus on safety, programme and keeping traffic moving.
Typical support includes
Product Selection & Manufacturing
We review drawings, specifications and site requirements to select the right products and materials, and where bespoke components are required we support with manufacture and procurement — with fabrication delivered to EN1090 (EXC3).
