What Thomas & Adamson does

Thomas & Adamson is a UK-headquartered construction and property consultancy founded in 1935, providing cost and project management, building surveying, hotel consultancy, construction safety (CDM), and project monitoring services. It serves enterprise and public-sector clients across health, life sciences, major infrastructure, defence, commercial, build-to-rent, and hospitality sectors, with named mandates including the Hinkley Point and Sizewell C nuclear power stations and the Old Oak Common railway station development. The firm operates from offices in Scotland, London, and the Middle East with a team of over 100 professionals, and in September 2025 extended its service portfolio with a Digital Measured Survey Service led by a dedicated lead surveyor, using 3D laser scanning and drone-based geospatial measurement to deliver faster, higher-precision site data to construction and property clients.

The firm's revenue model is professional services: project-based consulting engagements priced via quote-based fees, with revenue tied to staffing and contract duration rather than product or platform licensing. Distribution is direct, with multidisciplinary project teams based in regional offices delivering services to enterprise clients; go-to-market leverages the firm's 90-year brand heritage and credentials on nationally significant infrastructure projects, supported by industry press visibility and a corporate web presence.

Since 2024 Thomas & Adamson has operated as a wholly-owned subsidiary of Egis Group, a global engineering, consulting, and operations firm with approximately 22,000 employees across more than 70 countries. Egis formally rebranded Thomas & Adamson under its own brand in March 2026, with the legacy website redirecting to Egis; the firm retains its team and operating identity while gaining access to Egis's multinational resourcing and cross-border project delivery capabilities.
