IEQ Investigation Process

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) Investigated: August 16 and September 17, 2018

Mold growth was observed on the ceiling (approximately two-square inches). The mold growth was cleaned/disinfected upon discovery.

The roof was assessed by Building Services. The roof contained penetrations allowing for water to enter the portable. The roof was repaired.

After the roof was repaired, the Office of the Environment planned on making a test cut into the ceiling (where the mold was found) in order to assess the backside of the ceiling. Prior to this occurring, the school called indicating the portable had leaked again (9/17/2018).

The Office of the Environment visited the site and found a possible moisture intrusion concern with the front wall of the portable. This leak was not in proximity to the mold found on the ceiling and was believed to be occurring for a different reason.

Building Services returned to inspect the building envelope and identified concerns with the flashing detail.

The portable was vacated due to the active leak.

The portable is over 18-years old.

The Office of the Environment understands the portable will be demolished and replaced when funding becomes available.The portable will remain unoccupied.
