Off-Site Glazing, On-Site Outcomes: Lessons from a Modular Precast Tower

This session presents Tower D within the Valhalla Village development in Toronto, a modular precast tower utilizing pre-glazed concrete panels. It explores how off-site fabrication influences building envelope design, detailing, and QA/QC processes. Drawing on both in-plant testing and observed on-site performance, the presentation highlights key challenges and lessons learned from interface performance in managing air, water, and thermal control continuity.
