One Bloor West
One Bloor West, formerly known as The One, located at Yonge and Bloor Streets, will grace the Toronto skyline with an ambitious and thoughtful design. This 85-storey tower, designed by Foster + Partners in collaboration with Core Architects, now stands as the tallest residential building in the country and the second-tallest man-made structure after the CN Tower. Walters Group played a pivotal role in this skyline-defining project, supplying and installing over 4,500 tons of structural steel, including the fabrication of eight mega-columns and diagonal bracing that support the tower’s distinctive design
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 to fabricate and install over 4,500 tons of structural steel (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.
