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: June 7, 29, July 12, and August 18, 2022
The ceiling appeared water damaged (paint bubbling) at the corner of the locker room and shower area.
Elevated moisture was detected in this area. A nearby ceiling access panel was opened.
Approximately five square feet of mold growth was observed on the top of the ceiling.
Building Maintenance reported concerns with the Heating and Ventilation and Air Conditioning (HVAC) drain pan (Air Handling Unit -4 (AHU-4) located in the mechanical penthouse located above the locker rooms.
Building Maintenance requested that the drywall ceiling be removed in both the girls and boys locker rooms to further assess the potential future leaks.
Due to the identified mold growth and the potential to identify additional mold growth during work, the drywall ceiling removal was completed by a board-approved restoration contractor. Critical barriers such as doors and ventilation supplies/exhausts were covered with 6-mil polyethylene sheeting during removal. No additional mold growth was identified during the removal project within the Boys and Girls Locker Room.
Additional mold growth was identified in the Boys Bathroom that adjoins the locker rooms during the project. The penthouse mechanical room is also located above two bathrooms. The mold growth was identified on the topside of the drywall ceiling.
An access panel was also cut into the Girls Bathroom for assessment. No mold growth was observed on the Girls Bathroom side. The drywall ceiling in the Girls Bathroom remains.
Building Maintenance (HVAC) utilized a contractor to replace the drain pan for AHU-4. Work was completed on August 2, 2022.
A board-approved restoration contractor removed the drywall ceiling in the Boys and Girls Locker Room and the Boys Bathroom that adjoins the Locker Rooms. Building Maintenance replaced the ceilings in these areas with drop-ceiling. Removal work for the three areas was completed on August 14, 2022.
