Structurally, this standard 9 storey building consisted of structural framing, concrete slabs, block and brick facade components and concrete footings and foundations.

The goal of the project was to demolish the entire 9-storey building down to grade level and remove all below grade elements such as the footings and foundations. Once all concrete was removed, the empty basement had to be backfilled.

The challenge was space—there was no space between 89 Avenue road and the neighbouring buildings. In order to utilize our equipment safely in this tight space, machines were driven through the building so that the structure could be demolished from the inside out.

Logistics and close proximity to neighbouring buildings as well as the roadways along Avenue Road were both major challenges during this project. PDI used outriggers and netting along the north and south elevations to allow for a top-down demolition, preventing debris from falling against, or onto, adjacent structures.




Watch Priestly Demolition do the unthinkable—and take down the entire Gardiner Expressway Eastbound Ramp in just 5 weekends. This is a fresh new look at the masters of bridge demolition. See drone footage, time-lapse video, and project highlights of this rapid demo from the PDI team, plus a behind the scenes look at how this project plan comes together, and the people who make it happen.

Victor Mine, Ontario’s First and Only Open Pit Diamond Mine

Must see demolition of the Victor Mine, where calling in for backup isn't an option. Priestly Demolition flies in additional heavy equipment by Hercules aircrafts, to complete the project in this remote location near James Bay in Northern Ontario.

Underwater Demolition of the Glen Miller Dam 3

Priestly Demolition dives into the murky waters of the Trent Severn Waterway—hammering and removing concrete 16 feet below the surface. This underwater demolition provides a whole new set of challenges, but that's nothing new for PDI and the bigger the challenge, the more excited we get. Watch now to see how it's done.
