About Us

The Firm

Structures need to stand the test of time. Quality and longevity, it’s at the heart of our firm.

TLSE Engineering was founded in Vancouver, BC, in 1990 with a vision to make breathtaking structures a reality through a collaborative engineering and architectural effort. We are an independent firm of highly qualified structural engineering consultants and an active member of the Structural Engineers Association of British Columbia (SEABC) and the Engineers and Geoscientists of British Columbia (EGBC). From low to high rises, we design all structural aspects of any type of building structure. We offer a range of services, and have expertise and proven experience with all major construction materials – concrete, steel, and timber. Our projects span across Canada and the globe including in China, Japan, Korea, Turkey, and the United States.

We are a recognized leader in the design of mid-rise timber structures, garnishing awards from the Canadian Wood Council (CWC). Most recently, CWC presented us with the Wood Design Award in 2015 and the Engineering Award in 2016.

We are also pleased to inform you that TLSE Engineering is Organizational Quality Management (OQM) certified by EGBC.
