Duo Construction Civil Engineering UK
Delivering large scale civil engineering, earthworks and remediation for UK infrastructure projects
Duo Construction is the civil engineering and infrastructure delivery division of Duo Group, providing specialist construction services for major projects across the UK. We focus on large scale earthworks, remediation and enabling works that support infrastructure, transport, energy, industrial and regeneration developments from early site preparation through to construction ready handover.
Our teams deliver complex construction scopes including bulk earthworks, ground improvement, material processing and reuse, drainage networks, reinforced concrete structures and environmental mitigation works. We operate on both brownfield and greenfield sites, often within constrained environments and live infrastructure corridors, where safety, quality control and programme certainty are critical to project success.
We work directly with Tier 1 contractors, joint ventures, developers and public sector clients, bringing proven experience from nationally significant schemes such as HS2, major motorway upgrades and long term industrial developments. Our approach is built around practical delivery, strong site leadership and value engineering, with a clear focus on reducing risk, managing cost and reusing materials on site wherever possible to improve sustainability outcomes.
Below are examples of key projects delivered by Duo Construction, demonstrating our capability to manage complex scopes, large volumes and challenging conditions at scale.
