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 of Assessment: August 14 and 15, 2023

The Office of the Environment was contacted on August 14, 2023 to evaluate water damaged materials from a leak that occurred on August 10, 2023, due to an open valve on the Cradlerock Elementary side of the facility (Room 194). Please see IEQ Report CXCRES2023000299 regarding the response actions associated with Cradlerock Elementary. 

During the assessment, it was identified that water (originating from Room 194) impacted drywall within Room 196 of Lake Elkhorn. 

Moisture impacted drywall was identified directly adjoining a built-in instrument storage rack constructed of wood. The storage rack was removed from the wall to determine if additional drywall was impacted. 

Elevated moisture was detected in the drywall and base portions of the instrument storage rack directly contacting the drywall. Additionally, suspect mold growth was also observed on the wooden base of the storage rack and behind the cove base adjacent to the storage rack. 

Corrective Actions
August 15th, 2023

The cove base, drywall, and impacted portions of the built-in were removed by the board-approved restoration contractor. 

Building Maintenance was reminded to inform the Office of the Environment as soon as reasonably possible should a leak impact drywall or wooden materials.
