The smaller buildings at the site of the former Grace Hospital in Windsor are to be torn down this week.

The Brett Building, at the corner of University and Oak avenues, as well as the boiler house and carpenter's building, will come down this week if all goes according to plan.

City engineer Mario Sonego says the demolition company has finished clearing those structures of any hazardous materials, such as asbestos.

"It went quite well, actually, from what I understand. That's good," Sonego said. "We've still got a lot of work to do inside the big former hospital part of the building. So that's going to take a little longer, but so far, no surprises, and things have gone on schedule."

Sonego says a special excavator needed for the demolition has arrived in Windsor.

"They're going to be starting on the smaller buildings and start nibbling away with their claws and excavators," Sonego said. "It won't be like a dramatic blowing up or anything like that."

The full demolition is supposed to take five months.
