UHN Bickle Centre for Complex Continuing Care
TORONTO, ONTARIO
Acting as the Prime Consultant, this Project includes the replacement of nine air handling units, related return/exhaust fans, controls systems and associated electrical infrastructure in a phased approach, with temporary cooling/heating in order to keep the Facility fully operational. The Project also includes replacement of the normal and emergency power motor control centres and starters in the four major mechanical rooms and various energy saving initiatives including the conversation of the ventilation and hydronic systems to variable flow, installation of chilled water “energy” control valves on the air handling units and the installation of a heat recovery system on the Building’s exhaust.
Phase 1 of the project focused on the Level 1 Mechanical Rooms while Phases 2 and 3 involve the required work in Penthouse Mechanical Rooms and on-floor work to add variable air volume boxes to the air distribution system.
To mitigate risk on the project, Quasar and UHN opted for a CCDC5B procurement model to allow for Trade input on constructability and phasing to be incorporated into the design and finalization of documents prior to proceeding with construction. Quasar assisted with the creation and evaluation of the RFP for construction management services and subsequently worked alongside the Construction Manager / General Contractor in addressing critical items to the success of the project including early procurement of major equipment, provision of temporary ventilation systems and defining detailed switchover procedures to minimize downtime.
Due to the very tight tolerances in the existing mechanical rooms, and the desire to keep the facility fully operational throughout construction, Quasar performed a 3D point cloud scan of each mechanical room which was imported into the BIM design model for the project. This allowed for exact tie-in points to existing services to be identified and enabled precise dimensional accuracy of the new equipment relative to existing services/equipment, ensuring potential inter-ferences were resolved during the design phase rather than during the construction phase. The use of this technology and technique has since become Quasar’s standard for delivering complex work in existing mechanical rooms.
