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: April 3, 2019 and May 13, 2019
The stained tile in the closet was damaged due to water. The teacher indicated this tile becomes wet after heavy rain fall.
No odor or mold growth was observed above the drop-ceiling.
The fireproofing located above the drop-ceiling was probed with a moisture meter. No elevated moisture was detected.
No duct work or plumbing was observed above the drop-ceiling with the exception of one fire suppression line. This line was not located directly above the stained ceiling tile.
The roof was inspected and the sealing of the coping/flashing was questionable.
Building Services (Roofing) was contacted. Building Services was aware of the issue and indicated the flashing was missing an end-dam. Building Services was already working to schedule a contractor to correct the issue.
The Office of the Environment revisited the area as it was raining (5/13). No water infiltration was observed. The rain may not have been "heavy" enough to cause infiltration.
The stained ceiling tile was replaced by custodial services as it was damaged from water infiltration.
Building Services (roofing) worked with a roofing contractor to open the wall and perform the repairs.
