Last month, crews from TMG Builders were in the process of preparing a block of heritage building frontages at the site of Bazis and Plaza's 1 Yorkville, a 58-storey condominium tower designed by architect Roy Varacalli with heritage restoration elements overseen by ERA Architects. In the past few weeks, the complex and delicate process of demolishing the rear portions of these heritage structures has been completed, and work has now moved onto the shoring phase of construction.

It is assumed that TMG Builders will be using the pile and lagging system for 1 Yorkville's shoring as a waterproof caisson should not be required here. The process involves the insertion of vertical steel wide flange beams, or soldier piles, into the earth, which are then supported by the addition of horizontal timber lagging as excavation progresses down towards the development's foundations below a five-storey underground parking garage.

The real trick at 1 Yorkville will be to keep the foundations of the heritage frontages facing Yonge Street intact as as excavation and then construction proceeds immediately behind them. Approximately the first 10 metres of each of those buildings have been saved and that portion will be restored and reopened as retail along Yonge Street when construction is finished. Above and behind them, residents of the 577 new homes in the development will enjoy 1,207 square metres of indoor amenity space, plus an additional 830 square metres of outdoor amenity space, most of it occupying the fourth and fifth floors and adjacent outdoor spaces, with the remainder on the roof of the tower.
