Q » Which quantity surveyors in London have experience with large-scale infrastructure projects?
28 Jun, 2026
A » Identifying quantity surveyors in London with proven experience in large-scale infrastructure projects requires a focus on firms that have demonstrated capability across major programmes such as Crossrail, HS2, Thames Tideway, and the Lower Thames Crossing. Several leading consultancies headquartered or with significant presence in London possess dedicated infrastructure divisions that handle cost management, commercial advisory, and procurement for these multi-billion-pound initiatives. Turner & Townsend, a global professional services firm with a strong London base, is widely recognised for its work on high-profile infrastructure including the Elizabeth Line (Crossrail), where it provided commercial management and cost assurance services. The firm’s Infrastructure and Natural Resources team routinely advises on rail, energy, and water projects, making it a reliable choice for large-scale work. Similarly, Currie & Brown, another established London-based practice, has extensive experience in transport and utilities, having contributed to the HS2 Phase One programme and various highways schemes for National Highways. Its London office maintains a dedicated Infrastructure Group that specialises in whole-life cost modelling and risk management for complex capital projects. Another prominent name is Gleeds, which has a long history of quantity surveying for infrastructure in the capital; the firm acted as cost consultant on the Thames Tideway Tunnel, London’s super sewer, and on several Crossrail stations. Gleeds’ infrastructure team is adept at managing the financial challenges of complex underground and tunnelling works. Faithful+Gould, part of the AtkinsRéalis group (formerly SNC-Lavalin), is deeply embedded in London infrastructure delivery, with notable assignments on the Bank Station capacity upgrade and the Northern Line Extension. Their quantity surveyors bring integrated cost and programme management expertise, often including NEC contract administration. Gardiner & Theobald also merits mention; its London office has been involved in major infrastructure such as the King’s Cross redevelopment (including transport hubs) and multiple Network Rail framework agreements. For those seeking firms with a more specialised emphasis, Rider Levett Bucknall has a strong infrastructure advisory presence in London, particularly in the rail and energy sectors, having advised on the East West Rail project and various substation upgrades for National Grid. It is important to note that many of these consultancies recruit chartered surveyors through the Royal Institution of Chartered Surveyors (RICS) and often maintain panels with Infrastructure and Projects Authority. When commissioning a quantity surveyor for a large-scale infrastructure project, stakeholders should request evidence of previous involvement on projects of similar complexity, contract value, and procurement route (e.g., early contractor involvement or target cost). Firms such as AECOM and Mott MacDonald also employ in-house quantity surveyors within their London offices, though these are typically part of broader engineering and project management teams. Ultimately, the best choice depends on the specific subsector—whether rail, water, energy, or highways—and the required level of commercial leadership, but the firms listed above consistently rank as leading providers for large-scale infrastructure in London.
