This $30,000,000, twenty-three storey office complex, built in downtown Montreal for First Quebec Corporation (original developers), represents some 325,000 square feet of interior office space. Construction was significantly complicated by the fact that the structure envelops a massive, pre-existing substation and rectifier station providing power and ventilation to the entire Montreal subway system. A pedestrian tunnel below the street to the existing metro was also part of the project which was completed within budget, and within the scheduled eighteen month time period.
