<br />. Basement ceilings contain sporadic damage such as water stains, peeling paint, and <br />visible fungal contamination. Additional contamination likely occurs on concealed <br />surfaces of damaged gypsum board ceilings and ceiling tiles. <br /> <br />. Gypsum wallboard at the perimeter wall of the Women's restroom contains visible water <br />damage and fungal contamination. The observed conditions are consistent with effects <br />caused by moisture intrusion through foundation walls. <br /> <br />. Exterior grading and walkways exhibits neutral to negative slope towards foundation <br />surfaces. The observed conditions will lead to high moisture burdens which further <br />increase the likelihood of moisture intrusion, water damage, and fungal contamination. <br /> <br />Above-Grade Walls: City Hall BuHdlng <br /> <br />The following conditions are suggestive of prior moisture intrusion and a moderate to high likelihood of <br />sporadic fungal contamination within perimeter wall assemblies: <br /> <br />. Exterior surfaces of the brick veneer exhibit prominent water stains and efflorescence. <br />The observed conditions are consistent with effects caused by high water burdens <br />resulting from prolonged exposures to water from landscape irrigation systems., <br /> <br />. Mortar joints in the brick veneer exhibit significant deterioration. The observed conditions <br />were likely exacerbated by high water burdens. Deteriorated mortar joints also represent <br />prObable routes for moisture intrusion. <br /> <br />. The brick veneer exhibits numerous cracks that are likely due to structural ,settling. I <br />cannot rule out the possibility of cracking due to expansion and contraction of water- <br />damaged substrates. Unsealed cracks represent probable routes for moisture Intrusion. <br /> <br />. Weep holes are installed at lintels above doors and windows; however, weep holes occur <br />irregularly. at the base of walls. The observed conditions do not provided adequate <br />drainage of moisture that may enter the drainage plane (I.e. behind the brick). The <br />likelihood of mortar occlusion behind the brick veneer remains unresolved. <br /> <br />. Brick sills lack positive slope away from window openings. Mortar joints elt the Sills show <br />significant deterioration. The observed conditions represent probable routes for moisture <br />intrusion. . <br /> <br />· Caulked joints at windows and expansion joints exhibit significant deterioration. The <br />observed conditions represent probable routes for moisture intrusion. <br /> <br />· Seals at window frames exhibit significant deterioration. The observed conditions <br />represent probable routes for moisture intrusion. Window frames exhibit water stains and <br />corrosion. Water stains also occur between window panes. <br /> <br />· Painted gypsum wallboard at perimeter walls exhibit blistering, peeling paint, aM <br />sporadic fungal growth. The observed conditions are consistent with effects caused by <br />moisture Intrusion at perimeter walls and windows. <br /> <br />Plumbing Failures: City Hall Building <br /> <br />Several ceilings exhibit water stains consistent with effects caused by plumbing leaks and/or leaks <br />from condensate lines from HVAC systems. Concealed surfaces may harbor fungal contamination. <br /> <br />Built Environments.
