Repair and Renew

Infrared thermographic scans were performed on the exterior walls and roofs of 21 Melinda St., 25 King St. W., 30 Wellington St. W., and 199 Bay St. to identify thermal bridging and air leakage, following ASTM E1186-17 under pressurized and depressurized conditions.

Anomalies were documented, with recommendations for further investigation, glazing retrofits, and additional roof scans in warmer conditions to assess moisture issues. Findings and thermographic images were provided in detailed reports to guide remediation and improve thermal performance.

This new 7-storey, 600,000 square-foot hospital, connected to a 145-bed long-term care facility, includes 164 beds and expanded cancer care services. Building envelope scope included 3D thermal modeling, drawing and glazing fabrication reviews, construction monitoring, performance verification testing, and LEED v4 Building Envelope Commissioning. 

For over a decade, Engineering Link has supported Colliers with the annual glass replacement program at Royal Bank Plaza. We developed a glass purchasing program based on failure trends, provide technical guidance for reglazing and spandrel panel refurbishment, and conduct site inspections during replacement. Our role has expanded to include investigations and repair detailing for curtain wall leaks.

A phased IGU replacement program was developed following a detailed window assessment that included drawing reviews, field investigations, exploratory openings, infrared scans, and thermal modeling. Design and contract administration began in early 2020 for approximately 40,000 sf of glazing over three years, targeting energy-efficient retrofits that preserved the original appearance. The selected solution aligned with York Region’s carbon-neutral goals, improving window performance by 20% while retaining existing frames to reduce costs and disruptions.
