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 existing stadium provides seating surrounding all sides of the single use soccer pitch. The north, south and east seating stands include exterior concourses at grade for access and washrooms and concession. The larger west stands include an upper exterior concourse as well as interior functions such as change rooms, team offices and the like. The west stands have two levels of seating also includes an upper media level.
The expansion includes 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. Construction will be performed during the 2015 and 2016 off-seasons commencing in the fall and ending in the spring of each year.
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.
