The condition of the existing concrete cap, adjacent barrel vaulted ceilings, and masonry walls of the room and surrounding tunnel were investigated. While the overall condition and structural integrity of the masonry wall and ceiling are stable, some notable cracks in the masonry, missing masonry, staining and paint failure is evidence of water infiltration. The water infiltration has caused electrical outlets to be abandoned and needs to be addressed to curtail further damage to the structure.
