Date(s) of Assessment: August 18 and 21, 2023
The Office of the Environment was requested by Building Maintenance to assess moisture impacted materials regarding a slow leak within Classroom A6.
Building Maintenance (Plumbing) reported that the leak had been repaired.
The Office of the Environment visited the site on August 18, 2023 to collect moisture readings and observe the impacted area. The Office of the Environment found that wooden cabinetry, drywall behind the cabinet, drywall on the left hand side of the cabinet, drywall within the hallway adjacent to the cabinetry, and carpet beneath the cabinetry were moisture impacted. Since the Office of the Environment could not determine how long the materials had been impacted, a restoration contractor was utilized to remove the materials.
In order to remove impacted drywall behind the cabinetry, the cabinetry was removed from the wall.
Upon removal, visible mold growth was identified on the bottom portions of the cabinetry and drywall behind cabinetry (eleven square feet in total).
A board-approved contractor removed the impacted casework, drywall, and carpet from the space and discarded. Work was completed within a containment and High Efficiency Particulate Air (HEPA) scrubbers operating within the work space.
