Union Station in Toronto is the busiest transportation hub in all of Canada. As the gateway to the downtown core, it provides access to various forms of transportation. The train area of the station is covered by a heritage designated structure, built in the late 1920s, and covers eight acres. As part of a complete roof replacement, one acre of the roof will be removed and a translucent glass structure will be built that will float above the existing structure. The construction is to be phased over seven years to maintain operations within the existing transit facility.
The project includes construction and rehabilitation of train platforms as well as the replacement of electrical, mechanical, and low voltage systems throughout the entire Train Shed. The project involved the survey and analysis of the existing heritage facility, developing a custom electrical and mechanical design solution, and the installation of the design including power distribution, lighting, specialty lighting, fire alarm, plumbing, drainage, HVAC, fire suppression, telecommunications, PA speakers, CCTV, PINS, and extensive EMI analysis as a result of the possibility of electrification of the trains through Union Station. A new electrical substation and emergency generator was installed to supply the lighting and systems throughout the Train Shed. Custom light fixtures were designed to match the original 1929 heritage light fixtures and an extensive raceway system was designed to work within the heritage limitations.
