Facing the room's green board, the bottom right of the window to right of the green board was wet per use of moisture meter.  Spotty mold growth was observed on the backside upon cutting an inspection square.

Portable 143

Drywall on both sides of the door (ramp side) was severely wet per use of moisture meter.  Heavy mold growth was observed on the backside upon cutting an inspection square.

Corrective Actions
July 19th, 2019

Building Services started removing impacted items (i.e. drywall, insulation, sub floor, door thresholds) and made some repairs, such as addressing deck at door (eliminate rain from pooling and entering under door), installing gutters above doors, and installed and sealed exterior lights at doorways.

The work became time consuming, thus a contractor was brought in to complete work which is in progress of being completed before the start of the school year.
