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.

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 CDMSEB 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.
