81 Bay Goes Above the Railways

February 16, 2018

Last summer, Walters was selected to supply the engineering, detailing, fabrication and erection of approximately 15,000T of structural steel at CIBC Square’s main office tower located at 81 Bay Street in Toronto. Our scope includes the main tower, podium, an overbuild and a PATH bridge (Toronto’s downtown pedestrian walkway) to the Air Canada Centre.

81 Bay’s overbuild development will be divided into six phases with erection scheduled from April 2018 to early 2021. This portion requires the supply, detailing, engineering, fabrication and erection of approximately 1,900 tons of structural steel and metal deck over Toronto’s Union Station rail corridor. Our scope of work also includes the delivery coordination for oversize trusses over land and by rail. Once complete, this overbuild will support a one-acre public park that will include a restaurant, skating rink, trees, hills and other landscaping features.

This project primarily consists of 100+ large trusses and infill, creating some interesting challenges ahead as some of the larger trusses will need to be carried into position on multiple rail cars. Just-in-time deliveries, due to very limited space for staging on-site, are also a challenge. In addition, all site work will need to be performed between midnight and 5am to prevent any disruptions to the on-going Toronto train schedules.
