This 14-storey residential building overlooks the exquisite High Park in the City of Toronto. The building is located on Line 2 of the TTC subway, requiring an isolation solution to eliminate the perceptibility of subway train vibration within the subject structure.

The 14-storey building High Park Condos constructed right on top of the Toronto subway required an isolation solution to eliminate train vibration within the building.

A 63 Hz disturbing frequency generated by subway, measured 3 to 5 floors below ground level, 0.3 to 0.4 mm/s rms. Target vibration isolation ranged from 0.05 to 0.10 mm/s rms.

A turn-key solution was implemented to meet the performance and construction demands by isolating the footings of the building, using two reinforced steel pans, one within the other, with CDM-SEB isolation pads in between.

This provided a series of advantages such as: a water-tight system, exact placement of CDM-SEB pads, formwork to accept footing/column rebar and concrete, even distribution of column loads, and fire protection, ultimately reducing on-site labour costs, nuisances, and slower installation.

No perceived or measured vibration has been reported in the building structure.
