Completed on-time and under-budget in June 2009, Bay Adelaide Centre, West Tower is Toronto’s first and only LEED® Certified Core and Shell Gold high-rise office building. The building is anchored by prestigious legal and accounting firms and represents a new standard for premier “AAA” class commercial properties. Integrating past and present, the project successfully incorporates the historic National Building façade at 347 Bay Street into the stunning design of a premier 51-storey office property.
The success of the building resulted in the need for the addition of mechanical and electrical systems to meet the demands of tenants. The need for a power supply required the addition of a new generator and provisions for another in the future. Located in the mechanical penthouse, the generator room was upgraded for vibration and acoustic isolation, electrical loadbank and diesel fuel supply.
Challenge: The primary structural challenge of the project was related to the installation of the new equipment at the top of a 51-storey office building in the downtown core of Toronto.
Solution: Working with an erection contractor, Entuitive assisted in developing an installation procedure within the constraints of the existing building structure and access to the generator room. A derrick was selected that could be transported to the roof via the service elevator in small pieces and then assembled in place. A crane location was selected that minimized the need to reinforce the roof while providing the needed crane radius for the generator and loadbank installations. The generator was installed in several sections that were small enough to fit through an existing mechanical shaft into the generator room.
