Scarborough Health Network - Airborne Isolation Rooms Renovation
Completion: August 25, 2025
Location: Scarborough
Size: 786
The Scarborough Health Network (SHN) project involved the construction of one airborne isolation room on Level 1, two airborne isolation rooms on Level 4, and upgrades to the Level 4 patient room HVAC services within the Crockford Pavilion at Scarborough General Hospital. Upon completion, the project delivers three fully redundant airborne isolation rooms and eliminates the split air-conditioning systems previously serving Level 4. While the hospital remained occupied throughout construction, the new airborne isolation rooms were vacant during renovations. All work was carried out in strict accordance with SHN Infection Prevention and Control (IPAC) requirements and the SHN contractor manual.
Mechanical Highlights:
As the mechanical contractor for this project, Kelson supplied and installed two air handling units, two condensing units, two mixed-flow Vari-Plume upblast laboratory exhaust fans, and a complete steam-to-glycol heating system skid with pump package. AHU-1 serves the Level 4 airborne isolation room and adjacent north patient rooms, while AHU-2 serves the Level 1 airborne isolation room and the Level 4 south patient rooms.
The scope also included relocating an existing rooftop unit to accommodate new glycol piping, with all new and relocated equipment fully integrated into the existing Building Automation System. A key challenge was performing work on the roof of an active hospital, including the safe installation of two 16,000-lb air handling units. Kelson worked closely with hospital staff to coordinate after-hours lifting operations, traffic management, and site logistics, ensuring minimal disruption to ongoing hospital operations.
