What Mason Clark Associates does

Mason Clark Associates Limited is a privately held UK multidisciplinary engineering consultancy, founded in 1990 and headquartered in Kingston upon Hull with additional offices in Leeds and York. The firm employs 51-100 people and delivers civil engineering, structural engineering, bridge engineering, conservation engineering, building surveying (including party wall and 3D reality capture), cost management/quantity surveying, and project management/CDM services.

Its core offering is a single-source, integrated consultancy rather than a packaged product, combining traditional engineering design with inspection technologies including 3D laser scanning, drone-assisted visual surveys and (from late 2025) the Sensequake Larzé wireless sensor platform integrated with the 3D-SAM cloud environment for Ambient Vibration Testing and Structural Health Monitoring. The firm is staffed with conservation-accredited engineers (CARE register), NEC4-accredited supervisors, and chartered members of IStructE and RICS, and is accredited to ISO 9001, ISO 14001, Constructionline Gold, CHAS, Cyber Essentials and IStructE corporate membership.

Revenue is generated on a fee-for-service basis via direct commissions and through appointments to public-sector professional services frameworks (YORconsult3, EN:Procure Gen-4 to 2029, Fusion21, Hull City Council Engineering & Regeneration). The firm's primary customers are local authorities in Yorkshire and the Humber (Hull City Council, Leeds City Council, East Riding of Yorkshire Council, North Lincolnshire Council, City of York Council) for infrastructure, bridge and conservation work; secondary segments include heritage trusts, education institutions, water utilities and private commercial clients.
