Date(s) of Assessment: July 3 - 9, and 31, 2019
On July 31, 2019, the Office of Environment revisited the three portables after Building Services performed work. The questionable drywall in portables 127 and 128 were inspected and no mold growth was observed on backside of drywall or within the wall cavity. These areas were dry via use of a moisture meter.
Building Services removed a potion of drywall in Portable 116 and identified mold growth on the backside of the drywall.
Building Services removed impacted materials in Portable 116. They repaired possible moisture sources in all three portables, such as securing and sealing open screw holes and caulked the exterior lighting, mounted near the doors.
