Set to become Canada's tallest building, Mizrahi Developments' The One is preparing to pass a major milestone at Yonge and Bloor in Downtown Toronto, as the Foster + Partners and Core Architects-designed luxury condo and hotel project gears up for its first above-grade structural work since construction began in 2017. Over the last several months crews have formed the below-grade portions of the supercolumns that will support the hybrid exoskeleton structure, while constructing the parking levels and basement retail concourse level. With the lower levels in place, the next steps will see the ground floor to come together.
Following the forming of the P1 level—the uppermost of the project’s underground garage—crews formed a 609 m²/6,551ft² retail concourse level, which will combine with the flagship 831 m²/8,940 ft² retail space at ground level. Throughout November, just above where the concourse retail's ceiling will be installed, a network of steel cross-bracing has been attached to the supercolumns spanning the tower's footprint.
The lattice of bracing attaches to the vertical supercolumns at the point where the tower’s signature ground-floor canted columns will meet them. The outward pressure created by the massive load being transferred from above has to be counteracted, so the bracing will prevent the vertical columns from bowing outward as the tower loads are applied.
The connecting points between the vertical supercolumns and the canted columns are now visible at grade in the images above. Upcoming work on the ground floor will include the installation of the canted columns, which will allow for the retail space to be free of a central elevator core. Similarly, the podium floors above will be free of a central elevator core, and accessed from west side elevators. The central elevator core will only begin as of where the hotel floors begin in the tower above.
