Bill Collingwood

Bill has over 20 years of experience in the engineering and construction industry. He applies his industry experience and expertise to a variety of new construction projects including university and hospital campuses, multi-use high-rise structures on the Portland Waterfront, and wood-framed residential projects in the Pacific Northwest as well as many along the Oregon Coast.

Over his career, he has performed detailing of various complex assemblies such as unitized and stick-built curtain wall, window wall, metal panel, precast, and masonry veneers. His responsibilities in the field include review and assessment of all enclosure assemblies, such as below-grade waterproofing, window and wall cladding assemblies, waterproof deck and balcony membranes, and roofing membranes.

Bill has taken a lead role in condition assessment and investigation work, orchestrating and managing all aspects of field work. On the ground, he leads contractors and other RDH staff in collection of information through destructive and non-destructive efforts.

Since joining RDH in the Portland office in 2005, Bill’s mechanical engineering and building science background has been a valuable in-house resource, as he has contributed his HVAC and energy expertise to RDH projects.
