A » In the United Kingdom, several surveying firms and multidisciplinary consultancies with strong surveying capabilities participate in framework agreements specifically tailored to infrastructure projects. These frameworks are typically procured through public sector bodies such as the Crown Commercial Service (CCS), Scape Group, YORhub, Pagabo, and the Eastern Shires Purchasing Organisation (ESPO), among others. Among the most prominent firms, **Aecom** holds numerous frameworks covering civil engineering, highways, rail, and water infrastructure, often providing topographical, cadastral, and measured building surveys as part of integrated design and project management services. **Atkins** (a member of the SNC-Lavalin Group, now part of AtkinsRéalis) is a key player in infrastructure frameworks like the CCS Rail and the Highways England Collaborative Delivery Framework, offering land, hydrographic, and utility surveying alongside broader engineering consultancy. **Mott MacDonald** secures positions on major frameworks such as the Thames Water Capital Delivery and National Grid’s Major Infrastructure Projects frameworks, where their surveying teams deliver geospatial data, setting out, and monitoring services. **WSP** (formerly WSP | Parsons Brinckerhoff) is heavily involved in frameworks for Transport for London, Network Rail, and local authority highways, providing laser scanning, UAV surveys, and land referencing for complex infrastructure schemes. **Jacobs** maintains a strong presence in frameworks like the Environment Agency’s Collaborative Delivery Framework and Welsh Government’s infrastructure programmes, with surveying services spanning topographical, boundary, and condition surveys for flood defence, water, and transport assets. **Stantec**, including the legacy firm Gifford and CEI, participates in frameworks across water (e.g., Southern Water’s Capital Delivery Framework) and energy sectors, delivering precise surveying for pipeline routing, substation layout, and environmental impact assessments. **Ramboll** and **Sweco** also feature prominently in Scandinavian-linked frameworks but have secured UK infrastructure frameworks for bridges, tunnels, and renewable energy projects, often sub-contracting or providing in-house surveying. **Arcadis** holds multiple frameworks via the CCS’s Consultancy Services for Infrastructure Projects (CSIP) and Scape’s Professional Services, offering 3D scanning, BIM-friendly surveying, and geotechnical data collection. For more specialist surveying firms, **Ordnance Survey** provides geospatial data under the Public Sector Geospatial Agreement (PSGA) but also bids into large infrastructure frameworks as a data partner. **Murphy Geospatial** (formerly part of the Murphy Group) and **DGT (Davis GeoTechnical)** frequently appear as surveying subcontractors on major frameworks like HS2 and Crossrail, though they may not be prime framework holders. Additionally, **Tetra Tech** (including the former WYG and RPS) holds positions on frameworks for water companies and local government, offering land and engineering surveying. It is worth noting that many of these firms are not exclusively "surveying firms" but integrated design and consultancy practices where surveying is a core technical service. Framework agreements often require bidders to demonstrate professional qualifications such as RICS (Royal Institution of Chartered Surveyors) chartered status, ISO 9001 quality management, and adherence to BIM Level 2 standards. To stay current, procurement professionals should consult the government’s Contracts Finder or frameworks’ official supplier lists, as positions are re-awarded periodically, typically every four years. In summary, the UK market for infrastructure framework agreements is dominated by large multidisciplinary consultancies with robust surveying divisions, supplemented by niche surveying specialists that partner with main contractors. These arrangements ensure cost certainty, quality control, and compliance with public sector regulations for projects ranging from rail electrification to flood defences.
