The major 1,000m³ concrete pour we've all been waiting for at The One has finally happened. The Mizrahi Developments' project saw the walls of its fifth level poured on Saturday, October 23. The landmark retail, restaurant, hotel, and condo tower has been under construction since 2017, and crews will soon begin working to prepare forms for its sixth level, which will be the final non-repeated level in the tower.
In the shot above by crane operator Erik Millette, we can see how the wall forms have begun to be removed on the fifth floor. In the space where the red concrete pump reaches through, we can see a crew member on an scissor lift, the lift positioned in front of a doorway, similar to the one that can be seen in the same space further to the left. This space will effectively become a back-of-house function area for the future hotel. Other parts of this floor will feature The lobby of the hotel—also functioning as a condo amenity—plus a hotel bar and restaurant, will feature in other spaces on this level.
In our last update, we cited that more than 100 truckloads of concrete would be needed for the fifth floor pour of the building, designed by UK-based architects Foster + Partners with Toronto's Core Architects. Seen below on Saturday the 23rd, that concrete was brought to the site in what looked like a long parade of cement trucks which conveniently stationed themselves on the north side of a temporarily closed block of Bloor Street, across from the development.
In the image below from Wednesday, October 27, we can see a crew member standing atop a form recently filled with concrete, and next to a structural steel column encased with rebar. The formwork the crew member is atop of will be coming down shortly as the new concrete continues to cure, while formwork will next be placed to create the sixth floor slab. Form work will also be erected around the sixth and seventh floor columns ahead of the next concrete pour.
The sixth floor will be a shared amenities level for both the hotel and condo, while the seventh floor will be home to the first of 10 floors that will house hotel suites. Above that, all levels will be dedicated to the residential suites of the condo. The seventh floor will also be the first floor where forms will begin to be reused, as hotel levels will all be the same size and shape, allowing construction to pick up speed as reusing forms is much less time consuming. The 17th and 18th levels will be a mechanical suite for the building's lower floors, then residential levels — with another set of repeating layouts — begin on the 19th level.
The One was approved at a height of 85 storeys, 308.6 metres. The building is among the pair of projects currently contending for the title of Canada's tallest building, along with the 312.5-metre SkyTower at Pinnacle One Yonge, which is now in the early stages of construction only a couple of kilometres to the south. Seeking a height increase from the City, The One is now proposed to rise to 94 storeys and 338.3 metres high. If the increase is permitted, The One would retain the record as the tallest building in the country.
