The 7-storey, 102-unit apartment building was
constructed around 1981. The building includes a single-story underground
parkade which extends beyond the building perimeter. The slab over
the parkade provides landscaped areas at the front and rear as well
as some exterior parking spaces. The structure consists of post-tensioned
concrete slabs on a reinforced concrete frame. The original exterior
wall system consisted of steel stud construction with a conventional
stucco finish. The balconies typically include an enclosed solarium.
In 1994 and 1995, extensive repair and maintenance
work was implemented at the building and parkade to ensure the long
term serviceability of the structure. These repairs included the
following work:
non-destructive testing of all post-tensioning tendons
in the parkade and plaza deck using RIMT
replacement of 28 tendons designated by RIMT
concrete crack repairs on balconies
installation of waterproofing membrane on balconies,
on main floor and on plaza deck
waterproofing of PT anchors
re-cladding exterior walls with EIFS above second
floor, artificial stone at grade level and granite panels on commercial
area
replacement of masonry balcony panels with prefinished
aluminum railings
replacement of roofing system on commercial area
Based on the RIMT® assessment, 28 post-tensioning
tendons were replaced. Forty existing tendons were permanently wired
for RIMT® monitoring during the service life of the structure.
