The initial scope was to provide LEED Fundamental and Enhanced Commissioning services for Walsh-Bondfield Partnership in the P3 project to redevelop the hospital site in downtown Toronto.  The existing hospital was demolished, and the new construction of this 400,000 sq. ft. facility was completed in two phases, achieving LEED Gold Certification. The redeveloped Women’s College Hospital replaced all existing buildings and consolidated most hospital services in one location, enhancing the hospital’s stature as a leader in women’s health care, research, and education.

In mid-construction phase, our scope was expanded from LEED Commissioning to whole building commissioning as construction progressed. The scope expanded to further mechanical systems testing, and eventually to the whole building commissioning review, including mechanical, electrical, building envelope, vertical transportation and ICAT. This was an indication of the client’s confidence that Isotherm can ensure all commissioning elements are met in accordance with the Project Agreement and the PSOS. We also provided additional technical support for trouble-shooting specific difficult issues, e.g. optimizing controls sequence to work with the Enwave central steam and chilled water services, and isolation room and operating room pressurization issues.

Being able to communicate clearly and the ability to identify any gap in the commissioning process with the Project Agreement were the reasons why we were entrusted to manage the overall commissioning process for all building systems. The level of details we provided in design reviews and documentation reviews was valued.  The successful tracking and ultimately the resolution of the commissioning issues was one of the reasons why this project achieved LEED Gold certification when the initial target was silver rating.
