La Mirage is a 29-unit, 7-storey, terraced, cast-concrete apartment that was 22 years in age (constructed circa 1994) when the Strata Building Committee contacted BC Building Science to complete a building envelope renovation.
Working with the Strata’s Building Committee, we created a practical renovation strategy to address systemic failure where evident and we developed an effective retention and maintenance strategy at areas where systemic wall failure had not yet occurred.
The work recommended and completed included:
- Replacement of the existing stucco with new rainscreen wall;
- Cleaning, painting, and sealant replacement at all existing stucco clad walls;
- Complete refurbishment of the existing waterproofing systems at the concrete terraces;
- Application of a new, polyurethane-based waterproofing system over the original concrete surfaces;
- Full removal of the original planters and replacement of the original railings with new;
- Replacement of all windows and doors at all wall areas where new cladding was installed;
- Retention of the existing windows and doors at all wall surfaces where the cladding was retained;
- Full painting of the existing, sloped metal roof systems including fastener replacement; and
- Other typical or localized repair and maintenance work.
The final project cost was over $1.5M, inclusive of all costs.
