This new 577,000 sq. ft. 15-storey Class AAA office development features a cantilever podium supported with structural steel diagonal columns over a public space.
The project has four levels of underground commercial parking at 172,000 sq. ft. with 231 stalls.
It also includes a below-grade tunnel connection to the existing heritage buildings at 510 Front Street ands 495 to 517 Wellington Street.
The primary structure consists of cast-in-place concrete slabs with exposed tapered drop panels.
There are three central concrete cores that act as the lateral force resisting system.
The main structural challenge was designing the five-storey overhang podium that cantilevers approximately 15m from the building face with diagonal steel structs, over a six-storey high public outdoor space.
