Experience Profile: TTC Union Station Upgrades

LRI ensured that the redesign of TTC’s iconic, foremost station met the fire protection and life safety requirements of the Building Code.

The redesign of the Toronto Transit Commission’s primary station involved the renovation of the existing concourse level at Union Station, modification of the existing Union Station platform to serve the University Line, and the construction of a new platform, to better serve the Yonge Line.

LRI’s extensive transit experience proved valuable, as it allowed the design team to navigate the approach to application of the Building Code, for this complex and critical subway improvement program. The team provided an extensive suite of services, including: the review of drawings, preparation of Building Code approaches and reports, performance-level evaluations, development of interpretations to address unique design challenges, and negotiations with the Authority Having Jurisdiction (AHJ). 

For this multi-faceted, composite project, LRI prepared an approach to station emergen-cy ventilation, to improve the existing performance level of the station. LRI collaborated with the City of Toronto, to discuss this approach and the degree of compliance to the Building Code, which was ultimately deemed satisfactory by the City.
