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(s) of Assessment: October 9 & 10, 2024
Building maintenance reported that a plumbing leak occurred due to a damaged hot water coil associated with the Air Handling Unit (AHU) located above the room.
The leak impacted carpeted floor in rooms C29 & C28 and the drywall walls separating rooms C29 & C28. Ceiling tiles in room C29 were also impacted by the leak.
Building Maintenance (HVAC) isolated the leak.

Room C28 & C29
- No elevated moisture was detected in the carpet or drywall.
Hallway Adjoining C28 & C29
- No elevated moisture was detected in the drywall.
Conclusion
Building maintenance was informed that materials were dry and that cove base could be replaced.
The above drying activities were conducted to prevent a shift in fungal ecology due to the moisture intrusion event.
Building Maintenance to replace damaged hot water coil which caused the leak.
Water damaged ceiling tiles were removed and replaced with new ceiling tiles.
