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)
Dates of Assessment: November 8, 9, 24, December 8, 2021, and February 2, 2022.
November 8, 2021: Building Services contacted the Office of Environment regarding a small flooding event impacting the hallway outside of the auditorium. The hallway floor tile and carpeting and a 10' x 10' section wood stage (doorway to hall) were impacted. The cause was due to a slop sink left on within a custodial closet. Building Services did the initial assessment and deployed fans and dehumidifiers. The base board of the stage was removed in order to force air under the wood floor (void between stage and wall).
November 9, 2021: The Office of Environment performed an assessment. No additional areas of concern. The carpet in the auditorium lobby was dry as determined by the use of a moisture probe. The wood stage was still wet.
November 24, 2021: The Office of Environment checked on the drying of the stage. The stage was dry with an exception of a 4' x 4' section in the corner beside the door.
December 8, 2021: The Office of Environment determined the stage was completely dry with the use of a moisture meter calibrated for wood. The Office of Environment requested the underside of the wood be observed for mold growth in the area of the stage that took additional time to dry.
February 2, 2022: Building Services reported no mold growth was observed under the stage with the use of a flexible cable camera.
The above actions were taken to prevent the potential for microbial growth.
Building Services observed the underside of the wood stage impacted by water with the use of a flexible cable camera. No mold growth observed.
