Completed in 2008, BMO Field has a seating capacity of 20,000, is located in downtown Toronto and is home to Major Soccer League (MLS) franchise, Toronto FC. The enormous popularity of the Toronto FC and the stadium itself has influenced the ownership to expand the current seating capacity, add more types of seating and to construct a roof over all of the seating areas. The expansion will also include changes to the field and seating to allow for the use of the facility by a Canadian football team.
The expansion included extensive renovations to the west interior spaces, elimination of the north seating and rework of the southern region to accommodate for Canadian Football League matches, the addition of 7,500 seats as part of an upper deck to the east and the construction of a new roof over the east, west and south seating stands.
Challenge: The nature of the design and the space required the construction of a long span roof over the existing seating stands.
Solution: Multiple options for the roof structure were provided with consideration for cost and constructability. It was determined early on that the erection of the roof would drive the cost and scheme for the framing. In order to provide better optimal solutions, a structural steel sub-contractor was engaged early in the process to provide “design assist” and construction services.
