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: December 14, 2023
A few isolated locations of mold growth were observed on the backside of the drywall within the bulk head.
The Office of the Environment met with Building Maintenance, who reported the cause of the growth was due to leaks associated with the Heating Ventilation and Air Conditioning (HVAC) system above the drywall bulkhead. They reported the leaks are difficult to correct due to the configuration of the bulk head, interering with accesiblity to the equipment.
It was decided that the entire bulk-head would be removed to allow HVAC technicians more complete access to the equipment above. The drywall will be removed and replaced with a drop-ceiling.
A board-approved restoration contractor began the removal of the bulk-head on June 15, 2023. The Office of the Environment visited the site on June 20 and confirmed the removal of the bulk head. Work was conducted with an enclosure (polyethylene sheeting) and air scrubbers utilizing High Efficiency Particulate Air (HEPA) filters.
