  • 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)

No thermal anomalies indicative of moisture intrusion were detected. 

Under work order #72351, the HVAC unit that services the room was assessed by Building Services (HVAC). No concerns were identified.

The carpet was removed in one corner of the room. Under the carpet was another layer of fibrous material (likely the base of the carpet which had become delaminated from the top layer of carpet). This material had an evident musty odor.
