Governor General residence, Dome rehabilitation
BTC’s role on this project team was as Building Envelope Consultant, acting on behalf of the owner. Our responsibilities included design review, quality assurance, air leakage and thermographic testing of all building envelope components, including air/vapour barrier, waterproofing and thermal insulation of all new foundations, wall assemblies (Curtain wall, siding and masonry) and roofing. This project was particularly challenging to ensure fully airtight and watertight connections to the existing buildings, above occupied spaces in a cancer treatment centre.
