Summary

Extensive renovations to Union Station, in Toronto, ON, Canada’s busiest transportation hub and a National Historic Site will include expansion of the GO Transit concourse, new retail space and restoration of heritage elements.  Construction of the $640 million revitalization began in January of 2011.

The Union Station Revitalization includes a new 160,000 square-foot lower retail level, a new upper level transportation concourse area of about 126,000 square-feet for GO Transit passengers and a new northwest passage connecting Union Station to the underground PATH system at Wellington Street.

Concerns included noise, vibration and air contaminant emissions control, the potential for damage to heritage elements of the building structure during construction, and control of exhaust dispersion from two new generators. Novus’ involvement includes consultation during design and construction and focuses on:

  • Vibration control of building services in architecturally sensitive areas;
  • Control of noise from building services in the Great Hall and new retail areas;
  • Monitoring and assessment of ground and structural vibrations during construction;
  • Control of rail vibration impacts on new building services beneath the platform level; and
  • Regulatory environmental approval permitting.
