The West Tower of the Bay Adelaide Centre is a signature building in the heart of Toronto’s financial district. Part of a larger development consisting of three office towers, an urban park and an open plaza area, the West Tower takes the modernist form of a sheer tower of glass highlighted by elegantly notched corners. It became Toronto’s first high-rise office building to receive core and shell LEED Gold certification.
The structure’s reinforced concrete core combines with composite truss floor framing to maximize the number of floors while respecting City of Toronto shading guidelines. The building incorporates three large heritage façades, including the stone façade of the 1926 National Building.
Challenge: Develop a structural system for a 51-storey tower that helps the project meet a tight construction schedule.
Solution: Construction crews used jump form technology to build the core at the rate of one floor every three days. Long-span structural steel framing was built on three floors every ten days. Crews minimized lost days due to inclement weather using a protective RCS system and also carried out construction within an already built and occupied parking garage
