Date of Assessment: August 26, 2020
On August 25, 2020, Building Services contacted the Office of Environment regarding a work order (#164881) they were responding to involving a HVAC condensate overflow. The incident occurred August 21. Building Services started drying by removing carpet squares and vinyl cove base of the impacted drywall (walls surrounding the HVAC unit in the storage closet). Fans were placed to assist with drying.
On August 26, 2020, the Office of Environment assessed the situation. The carpet squares were in the main hallway. The back sides were dry, but some of the fabric surfaces were damp. The carpet squares were turned over to expose the fabric side. Fans were placed to assist with drying them. The drywall was dry with the exception to the corner of the closet where it protrudes out near the door of the principal's office.
Building Services was informed to remove the corner portion of the wall and provide air movement to the corner. The floor and drywall could be repaired the next day. Building Services was instructed to coordinate with Custodial Services to have the carpet squares cleaned.
Building Services completed drywall repair (except painting) and carpet install on August 28.
Building Services addressed the clogged HVAC condensate pan/drain.
The above actions were taken to prevent microbial growth resulting from the incident.
