What RDH Building Science does

RDH Building Science is a privately held, North American professional services firm founded in 1997 and headquartered in Burnaby, British Columbia. The firm delivers building enclosure consulting, facade engineering, structural engineering, construction management, energy and climate advisory, asset management, forensics, historic and heritage consulting, and applied research services to owners, developers, architects, contractors, and government entities. RDH employs 300 or more technical specialists across 16 offices in Canada and the United States, with US professional engineering services delivered through an affiliated Washington professional corporation.

The firm's service architecture is a single unified consulting practice supported by a separately monetized Training and Publications division. Core engagements are project-based and delivered directly to enterprise and institutional clients, with pricing determined by scope, complexity, and team composition rather than published rate cards. RDH's go-to-market combines relationship-based business development with extensive technical content marketing, including design guides, webinar series, and e-learning programs co-developed with industry associations (RAiNA, CAGBC, BC Housing) and manufacturers (ROCKWOOL). The firm generates revenue across at least ten market verticals including mixed-use, residential, civic and government, commercial office, healthcare, life sciences, higher education, K-12, spiritual and cultural, and aviation and transportation.

RDH operates as an employee-controlled partnership-style professional services firm with no disclosed external funding, private equity ownership, or institutional investors. Its competitive positioning rests on the depth of its senior technical bench, its library of standards-grade publications that are embedded in Canadian and US building codes and utility incentive programs, and its ability to integrate building science, structural, and facade engineering under one roof for complex envelope projects.
