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 8, 2019
It was reported that a custodial sink had been left on overnight, causing water to leak into the Media Work Room.
The origin of the leak (2nd Floor Custodial Closet) was assessed. No porous materials were impacted (floor tile, concrete block walls, and metal shelving).
Areas below the custodial closet were assessed:
Several boxes were found to be saturated.
The ceiling tiles had already been replaced prior to the Office of the Environment arriving onsite.
Approximately 10 Linear Feet of fiberglass pipe insulation was identified to be wet.
While above the drop-ceiling, a hole was observed in the ductwork/VAV box. The hole was covered with an air filter rather than sealed with sheet-metal. Although unrelated to the leak, this issue also needs to be resolved.
The wood cabinetry below the leak was assessed using a moisture meter (wood setting). No elevated moisture was detected.
The wet boxes were removed by the Office of the Environment and were to be discarded by Custodial Services.
The impacted pipe insulation was replaced by Building Services (HVAC).
A work order was created for Building Services to assess and correct the holes in the duct work.
