What Chapmanbdsp does

Chapmanbdsp is an independent UK-headquartered building services engineering and environmental design consultancy founded in 1972, operating across five offices in London, Birmingham, Dubai, Abu Dhabi, and Riyadh with a workforce of 200+ multidisciplinary staff. The firm delivers an integrated portfolio of services spanning MEP (Mechanical, Electrical and Public Health) engineering, environmental and sustainability consultancy, vertical transportation design, advisory services, and smart building consultancy, supported by two proprietary tools: a BRE-validated Carbon Calculator and an in-house Sustainability Implementation Plan (SIP) web platform covering 16 environmental concepts. Chapmanbdsp has collaborated across 32 countries on landmark schemes including Battersea Power Station, Britam Tower, 100 Liverpool Street, Kingston University Town House (2021 RIBA Stirling Prize winner), and multiple London School of Economics buildings. The firm holds ISO 9001 and ISO 14001 certifications, Investors in People Silver/Gold accreditations, and operates as a CIBSE-approved Training & Development provider since 2018.

The business model is professional services project-based consultancy, earning fees through fixed-fee engagements negotiated individually by project scope and complexity. Go-to-market is enterprise field sales: Board Directors personally manage relationships with developers (British Land, Battersea Power Station), institutions (LSE, Kingston University), and corporates (Apple, Capital Group, PwC UK, Diageo), supplemented by strategic appointments via competitive tendering and partnerships such as Keysource (data centres) and First Q Network (European delivery). Marketing is primarily content-led through website case studies, LinkedIn presence, and industry awards (BCO, RIBA, CTBUH, Prix Versailles). Customer segments span commercial real estate, education, hospitality, mixed-use developments, cultural venues, and residential, with recent deliberate expansion into data centres and smart building technology consulting.

Revenue mechanics rely on utilisation of qualified engineering staff against multi-stage (RIBA-aligned) project lifecycles, with recurring repeat-client work and adjacent regional expansion (notably Saudi Arabia for Vision 2030) acting as growth vectors. The firm is privately held with no disclosed parent company, external institutional investors, or acquisition history, owned by its founding partners and current Board.
