After another month of construction on The One, it’s becoming even harder to ignore the simple fact that this project is already changing the intersection of Yonge and Bloor, and is beginning to have the same effect in every direction. The Mizrahi Developments project has now surpassed the 30-storey mark on its journey to 85-storeys and supertall status, and we have another month’s worth of photos to pick from that show the latest milestones in moving the project forward.
Beginning with what we can see from ground level, last month's start of installation of the Rail Climbing System (RCS), described here, have continued over the last few weeks, showing more exciting progress. Just last week, Yonge Street was closed to traffic temporarily to allow the crew to safely hoist up more pieces of the RCS to be fixed to the building frame. Part of this process is captured in the image below.
The black section being hoisted up in the image above is part of a set of identical elements that are hung vertically from a pre-installed truss that spans horizontally across each face of the building. Together, they create a continuous wall that serves two important functions; first, the inside of the hanging element provides a safe working platform for the crew to continue the installation of the building envelope, providing wind protection and eliminating the need to lift them up from ground level. Secondly, the RCS also will protect the street from any falling debris, allowing the grade level retail unit to be opened safely while construction of the tower continues.
As we can see in the image below, the east wall of the RCS is now complete while work continues on the north wall. Not pictured, we can report that the west wall is also complete, while the south wall will feature a unique system that is designed to be installed around the crane.
Throughout the installation of the RCS, exterior finishing work has slowed down, but the crew was able to make some progress where they could on the west elevation. Last week saw the champagne-tinted cladding installed on the corner hangers, while the super-columns are still waiting for their cladding treatment. Also of note was the installation of glazing to seal the narrow volume connecting the tower to the western elevator structure (right). This linking volume will provide access into the tower spaces from the elevators to the four floors above the retail level, including where anyone going further up will transfer to the tower elevators.
Moving up to the current top of the tower, the slab of the 31st floor has been poured and set, and forming work has now moved on to creating the cruciform wall configuration. Thanks to the UT Forum contributors who track the building’s progress daily, we can estimate that the rate of forming is averaging out to about eight days for each level.
Finally, with the tower rising rapidly now, the latest update is that the crew has once again lifted the crane to a new height. The process involved two stages, pictured in the images below. First, a new connection point was installed, adding another point of contact between the crane and the tower at a higher position.
Next, a new section of the crane mast was hoisted up from ground level to be inserted into the existing mast with the help of a motorized system.
With the RCS nearly complete, the crew will soon be able to resume the installation of the exterior envelope across the standard height floors. Meanwhile, with the crane lifted, forming work will continue at its steady pace, building the tower up week by week.
