Project description:

The curtain wall is a two-storey set of windows on the east side of the Redpath Library Building. It was installed in 1952 and is nearing the end of its useful life. Replacing the curtain wall will prevent water infiltration. This renovation work consists of replacing the curtain wall of windows, a small section of flat roof, and the masonry surrounding the curtain wall. The project involves the removal of asbestos/contaminants in the areas surrounding the windows. The affected area will be completely wrapped, sealed off and inaccessible to ensure that staff and students are not exposed. Contractors will follow all the asbestos removal regulations as per the CSST standards. Precautions will be put into place during the work to protect the new McLennan-Redpath Terrace, and to separate the activities of the site from passersby. At no time will pedestrian circulation be prevented on the McLennan-Redpath Terrace.
