Toronto’s Air Canada Centre (ACC), home to the NHL’s Toronto Maple Leafs and the NBA’s Toronto Raptors, also serves as one of Southern Ontario’s premiere entertainment venues and convention centres.
Built within the façade of an art deco postal building, the ACC consists of seven main levels: two parking levels, the event surface, the main concourse, a suite level, an upper concourse, and media and group sales suites in the roof. Nestled in each end of the building are smaller lodge and balcony suite levels. The ACC also features an office tower.
The structural design included a cast-in-place concrete bowl supporting cast-in-place concrete floors and precast seating. The bowl was designed without expansion joints by carefully considering the internal forces of thermal and shrinkage effects.
Challenge: The client required an accelerated building schedule.
Solution: We worked with the construction management team, the structural steel subcontractor, and the mechanical engineering contractor to build mechanical rooms within the roof structure. To do this, we supported a partially completed roof using four temporary support towers inside the arena. By using this roof erection process, we shaved two months off the construction schedule.
