The Ricoh Coliseum, built in 1921 as part of the Canadian National Exhibition, now serves as the home arena for the AHL’s Toronto Marlies. Located next to a large convention centre, the renovated facility also hosts functions such as the Royal Canadian Horse Show and the Toronto International Boat Show.
The event surface was lowered to improve sightlines to accommodate the addition of hockey to the facility and 3,000 seats were added to the seating bowl. The project team also removed the main roof structure and replaced it with one 15-ft higher to accommodate private suites hung from its perimeter. Unlike the previous roof structure, the new roof structure can support the scoreboard and concert loading.
Challenge: The project team had to replace the roof quickly to meet an aggressive construction schedule while removing columns in the four corners of the Colisseum that obstructed sightlines.
Solution: The selection of structural framing was critical to meeting client deadlines. Existing perimeter masonry walls and the lower seating bowl were maintained, and new structural steel columns were located between the existing framing. These columns are supported by micro piles which, in turn, support the long-span structural steel roof.
