Go behind the scenes of BMO Field’s Phase 2 Expansion with PCL Senior Project Manager Neil Barrows to watch a 600ton crane lift roof sections into place, and learn about the complex engineering and planning involved in creating a new stadium within an existing structure. The massive roof trusses will be supported by four supercolumns constructed in each corner of the stadium. The supercolumns have been engineered to plug into bedrock using a system of micro piles drilled 7 meters into the ground. The east and west roof canopies are being built onsite in sections, and the south canopy will be assembled on site as one massive structure, to be lifted into position by the 600ton and 450ton crane.
