Destined to become Canada’s tallest building, the One, located at Yonge and Bloor Streets, will grace the Toronto skyline with an ambitious and thoughtful design. The 85-storey tower will combine seven levels of retail and restaurants, a 175-room hotel and a roughly 60-floor stack of condo apartments with multilevel penthouses.
The design scheme pushes the structure to the edges of the building. On each of its four sides are two “mega-columns,” as the architects call them, with diagonal bracing that extends up the façades, suspending a series of rectangular blocks within.
Walters has been contracted by Mizrahi Developments to fabricate and install the core structure (starting two levels underground and up to level nine above ground consisting of columns, diagonal bracing and horizontal ties) as well as adjacent structural steel for the podium and the facade retention.
As the concrete structure goes up, each corner of the building will have a set of two diagonal braces, every six floors. There will also be a tuned mass damper on the top of the building.
Walters’ team also assisted with some value engineering aspects of the project.
The construction of an 85-storey skyscraper in downtown Toronto at Bloor and Yonge will present some site logistics-related challenges.
Our detailing and engineering team is working hard on what the architect calls “mega-columns,” which are a set of four wide flange sections that will be put together in the shop and shipped to the site.
