Brian Chapnik MASc, PhD, PEng Principal Acoustical Engineer

Brian Chapnik is a founding Principal Engineer of HGC Engineering. Since 1990, Dr. Chapnik has been an active contributor on many building projects that have become well-known architectural landmarks in their localities. He works with leading developers, architects, engineers, builders, and planners, providing comprehensive assessment and design services for all acoustical-related aspects of large, complex and often mixed-use commercial, residential and institutional developments across North America.

Brian is an expert in achieving acoustical privacy and sound intelligibility goals of difficult acoustic spaces such as those found in corporate office towers and luxury high-rise condominiums. He is well respected for his analysis and control of structure-borne noise and vibration caused by building mechanical systems and for his expertise in optimizing building facades to mitigate environmental noise intrusions from highway, rail, air traffic, and industry.

Notable projects include One Bloor, a luxury residential high-rise at the corner of one of the most prominent intersections in downtown Toronto; MaRS Discovery District one of the world’s largest medical and technology urban innovation hubs; Women’s College Hospital redevelopment, an expansion of Canada’s leading academic, ambulatory hospital and a world leader in women’s health; and Ripley’s Aquarium of Canada, a major and popular Toronto tourist attraction.
