Date of Report
During a Tier II IEQ Walkthrough, elevated moisture was detected near the front doors of both portables.
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) of Assessment: August 13, 2019

The Office of the Environment requested Building Services (Carpentry) to remove and replace the wet drywall (it was undetermined how long the material had been wet and conditions behind the drywall had not yet been assessed).

Upon removal, mold growth was observed on the backside of the drywall to the right of both doors (two to four square feet per portable).

A definitive cause of the leak could not be determined (reported heavy rain while investigating). It is thought that the moisture and mold growth may have been the remnants of a historical issue that had since been corrected.

Corrective Actions
August 13th, 2019

The impacted drywall and wet insulation was removed. The door thresholds were re-set and the door frame was re-caulked as a precaution.
