Concern
During an IEQ Tier II Assessment, performed on August 9 and 12, 2019 by the Office of Environment, past mold growth was observed on the underside of several roof deck panels in weight and wrestling rooms.

Additionally, the casework along exterior wall in room A113 was identified to be wet per moisture meter. Wood rot and fungi was present at the base of the platform.
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)
Findings

Date(s) of Assessment: August 9, 12, and 13, 2019

Weight Room and Wresting Room

The impacted roof decking was addressed by a Board approved restoration contractor from August 14-16, 2019.  The surfaces were cleaned / disinfected and coated (spray applied) with an antimicrobial encapsulate.  To protect surfaces from paint and debris, the work areas were contained with 6-mil polyethylene sheeting. Air scrubbers were also operated within the work area during application.  The growth is considered to be from a past event and appeared to involve sections where roof penetrations (i.e. roof drains, HVAC equipment) exists and/or existed.

Room A113

The casework in room A113 was removed and the impacted trim (backside and base) were cleaned/disinfected and re-conditioned (i.e. sanded and painted) before re-installing.  The wood base platform was removed and then newly constructed.  An exterior expansion joint was not adequately sealed and gaps existed at the joint formed by the floor and wall.  All corrective action work was performed by HCPSS Building Services.
