Project Highlights:

Modern Niagara helped the City of Ottawa expand its 21st-century public transit system with expert electrical, mechanical, sheet metal and piping insulation services for a number of light-rail stations — several underground and one above-ground.

On the mechanical front, our work on the Lyon, Rideau, Parliament, and Lees Avenue stations included installing air handling units, refrigerant piping, condensing units and drainage as well as large bore tunnel piping at the above-ground location. Our team also:

  • Purchased, supplied and installed all mechanical equipment and heat tracing
  • Performed all sheet metal and piping works
  • Managed mechanical sub-trade insulation procurement
  • Supplied air and return-air systems (along with drawing air from large tunnel ventilation)
  • Installed employee washrooms, fans, VAVs, FCU’s heaters, AC units (elevator shafts), sanitary and storm pits (including pumps)
  • Performed the balancing on the mechanical system

Meanwhile, our electrical work included connections to high voltage transformers, a completely new distribution system, high-end lighting and lighting control system, fire alarm system, and conduit pathways for the communications and system wide track integrators. We were responsible for communications cabling as well as the P/A systems and Information Display systems at Rideau and Parliament stations. We were also responsible for all wiring and connections to all equipment supplied by the mechanical contractor, including exhaust fans, unit heaters, and air handling units.
