Opus Garage
Scope/Solutions
The Opus Garage was constructed in 1991 and was acquired by InterPark Holdings (InterPark). To provide visual interest, the garage’s exterior enclosure features a vinyl-coated chain link fence set in anodized aluminum channels at the parking slab perimeter and an aesthetic hollow structural steel tube design on the exterior. The coating on the steel tubes was peeling and the steel was corroding in isolated locations. InterPark wanted to better understand the facade’s maintenance needs and retained SGH to conduct a condition assessment of the facade elements, advise them if the steel tubes should be recoated, and provide an estimate of the costs associated with recoating.
Our investigation included:
- A visual survey of the steel tube assembly and the chain link fence
- Adhesion testing of the coating on the steel tubes
- Laboratory testing to measure the coating thickness, identify the coating composition to determine appropriate recoating options, look for surface defects that could affect recoating, and measure color fading
SGH observed localized areas where the coating was peeling and the steel was corroded. We determined that the steel frame coating, while generally sound, was reaching the end of its expected service life and recommended recoating it in the near future. SGH developed a conceptual recoating plan with cost estimates for InterPark’s planning or consideration.
