This twenty-seven storey office tower, designed by the architectural consortium Dimakopoulos Ass. and Larose, Laliberté et Pettrucci, opened in 1986. It occupies a very visible place on the Dorchester Square/Place du Canada heritage site. The paving stones on the nearly 10,000 sq. ft. esplanade around the building needed to be replaced and waterproofed. The work consisted in replacing every element of the system.
One of these elements contained asbestos. These fibrocement panels had to be decontaminated; this work was done outside normal business hours so as not to cause any inconvenience to the building’s employees or visitors. In addition, eight-foot-tall fences were put up for the safety of pedestrians.
- Removed the elements of the esplanade, including high-risk asbestos
- Re-did the waterproofing membrane
- Applied new insulation
- Laid new granite flagstones on studs
- Spot corrections to the surface level
