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(s): August 12, 14, & 16 2024
Custodial staff reported leaks on August 8, 2024 in the Administrative Area, Staff Lounge, and Outside Room 20 after a precipitation event.
Administrative Area
The cause of this leak was reported to be due to a roofing contractor failing to patch a roof cut previously made.
On August 13, 2024, the Office of the Environment performed an initial assessment. Impacted materials included drywall, which were reported to have been wet for several days. The contractor responsible removed impacted drywall on the same day.
On August 14, 2024, the Office of the Environment visited the site and identified additional moisture impacted drywall to be removed. The Office of the Environment sent an email, to building maintenance to have the contractor to remove the moisture impacted drywall.
On August 16, 2024, the Office of the Environment observed that moisture impacted drywall had been removed and new drywall installed in the administrative office.
Outside Room 20

The Office of the Environment did identify porous materials above the ceiling outside Room 20 (duct insulation).
Building Maintenance evaluated the wet duct insulation, and determined that rain came through the outside air dampers on RTU-1 and damaged the duct insulation and ceiling tiles outside of Room 20.
Staff Lounge
Several wet ceiling tiles were observed in the staff lounge after the precipitation event.
The Office of the Environment did not identify porous materials above the ceiling in the staff lounge.
Building Maintenance evaluated roofing above the staff lounge and identified various penetrations.
The below actions were completed to prevent microbial growth.
Room 20 - The duct insulation and water damaged ceiling tiles were removed and replaced.
Staff Lounge - Building maintenance patched the identifed roof penetrations in this area.
Administrative Area - Contractor placed temporary patch on failed roof patch and removed/replaced water damaged drywall.
