The $220M expansion to the Yorkdale Shopping Centre added an additional 145,000 sq. ft. and 40 new stores. RJC provided structural engineering consulting services for this retail expansion which included a two-storey steel superstructure and a five-level cast-in-place concrete underground parking structure. The design included a column-free loading dock with 100 feet long steel trusses supporting the superstructure above. RJC also provided design services for various feature elements, including a segmented-curved “Sail Wall” consisting of structural glass and architecturally exposed steel tubes, and a cable-stayed structural glass wall with custom stainless steel fittings.
