What Doig+Smith does

Doig+Smith is a UK-headquartered construction consultancy founded in 1936, delivering four core professional services — Cost Management, Project Management, Building Surveying, and Principal Designer — to public and private sector clients. It operates from three offices in Glasgow (headquarters, The Onyx Building, 215 Bothwell Street), Edinburgh (The Malt House, 2 Canning Street), and London (Tallis House, 2 Tallis Street). The firm has delivered projects across more than a dozen verticals including healthcare, education, transport and marine, aviation, commercial real estate, heritage, distilleries, and renewable energy, with individual project values ranging from approximately £380,000 to over £604 million (Queen Elizabeth University Hospital). Notable clients include NHS Lothian, RBS, British Airways, SSE, ScotRail, City of Edinburgh Council, and the University of Strathclyde, with several long-running framework and secondment relationships.

The business is structured as Doig and Smith Ltd, a private limited company registered in Scotland (company number SC372452), with no identified parent company, external investment, or institutional backing. Ownership is held by co-owners and directors including Fraser McQuarrie, Paul Owens, and Alastair Archibald. The firm employs between 101 and 250 staff across its three offices, organized into multi-disciplinary teams led by directors and technical directors with chartered credentials (RICS, APM). The leadership team includes a mix of senior directors, technical directors, associate directors, senior quantity surveyors, senior project managers, and trainees working toward chartership, indicating a structured career-development pipeline.

Revenue is generated through professional services fees negotiated on a project-by-project basis, procured via competitive tendering, framework agreements, and direct appointments. The firm does not publicly disclose revenue, and its go-to-market relies on direct B2B client engagement with public bodies and enterprise clients. Doig+Smith's differentiation rests on 89+ years of brand heritage, multi-disciplinary in-house capability, repeat client relationships, and accreditations including Investors in People Platinum and consecutive Building Magazine Top 50 Employer recognition (2016-2018). The firm shows no disclosed AI/ML capabilities, no proprietary software products, and no patents or technology assets beyond standard construction consultancy tooling.
