Construction of Bazis and Plaza's 1 Yorkville turned a major corner this past June, when the 58-storey, Roy Varacalli-designed condominium development reached grade in Toronto's posh Yorkville neighbourhood. Following the forming of the building's five-level below-grade parking garage, work on the first above-grade levels has been progressing slowly yet steadily on Yorkville Avenue, west of Yonge Street, with work now in full swing for 1 Yorkville's third floor.

The image below, captured along the project's Yorkville Avenue frontage, provides some insight into the forming process for structural columns. Rising from the third floor slab, two completed column sections can be seen on the right side of the image. Steel rebar protruding from the columns will be tied into more rebar, extending the columns' strength to the next level as the building grows higher. Formwork can be seen around one of the columns: the form holds liquid concrete is place as it cures.

Another view from roughly a week ago shows an interior stairwell installed to the height of a mid-level landing.

With forming for the third level well underway, the project's four-storey Victorian storefront facades along Yonge Street will soon have a rising tower as their new backdrop. During the later stages of construction, extensive cleaning and repair of these preserved frontages will give the project a heritage connection with Yonge Street's classic built form.

The most recent views from the site reveal the steel structural elements that will tie the preserved structure in with the new construction.

Unlike most point towers in new Toronto condominium developments, 1 Yorkville's floor plate remains a consistent size from the base of the tower all the way to the top. The unchanging slab means that construction should be speedy over the coming months, as fly forms will be able to be used on floor and floor.
