Identify deficiencies that may impact IEQ and/or sources of odor concerns. Typically includes the following depending on the nature of concern, but not limited to:
- interview/questionnaire of concern individual(s)
- inspection above drop ceiling (condition of roof deck, pipe insulation, return air plenum)
- inspection of ventilation system (operation of variable air volume box and outdoor air dampers, check controls, measurements of carbon dioxide, temperature and relative humidity, sources near outdoor air intake, measure return and supply air volume, cleanliness of coils, liner and condensate pan)
- inspection of exterior
- inspection below drop ceiling (housekeeping, sink and floor drain traps, signs of past and present moisture concern via visual and/or moisture meter, mold growth, ensure connection of current and capping of abandoned sanitary vents, odorizers, excessive plants and fabric items, identify potential pathways, and measure volatile organic compounds, carbon monoxide, and lighting)
Date of Assessment: April 7, 13, 14, 2026
The Office of the Environment observed water damaged drywall, delaminated cove base, and loose fiberglass wall panels within the custodial closet.
No visible mold growth was observed on the drywall beneath the fiberglass panels or cove base during the initial assessment.
Floor tiles surrounding the slop sink were found to be water damaged and loose; however, no visible mold growth was identified beneath the tiles at that time.
Exploratory demolition performed by Building Maintenance (Carpentry) on April 10, 2026, revealed mold growth on the backside of the drywall in the custodial closet and the adjacent offices.
During a follow-up site visit on April 13, 2026, the Office of the Environment observed approximately 40 square feet of visible mold growth on the backside of the drywall. The Office of the Environment, Building Maintenance (Carpentry) and a board approved restoration contractor developed a remediation plan while onsite.
At the time of assessment, the faucet was tested and normal use of the slop sink resulted in water splashing onto adjacent walls.
Building Maintenance (Plumbing) identified that the vacuum breaker on the faucet was leaking.
The observed splash patterns combined with the identified faucet deficiency, are considered the primary contributing factors to the mold growth in the custodial closet and adjacent offices.
The Office of the Environment utilized a board-approved restoration contractor to remove the impacted drywall and loose floor tiles. The contractor also cleaned and encapsulated surfaces to remain (framing and furniture).
A board approved contractor installed new drywall, waterproofing, and fiberglass panels in the custodial closet.
The vacuum breaker on the faucet was replaced.
