IR Thermography <br /> Amec Foster Wheeler utilized a Fluke TiR infrared (IR) camera to examine building materials for <br /> thermal gradients that could represent areas of possible excess moisture. Accessible building <br /> materials that appeared to be relatively cold in an IR image were assessed directly using a moisture <br /> meter and by manually examining materials. <br /> Moisture Testing <br /> Moisture content was measured in remaining gypsum wallboard (GWB) using a direct-reading <br /> moisture meter' and a non-penetrating moisture meter2. Moisture content readings were collected to <br /> identify building materials that contained sufficient moisture to support and amplify mold growth. The <br /> instruments used are designed for quantitative measurement of moisture content in wood, gypsum <br /> wallboard, plaster, and concrete. <br /> Wood with a moisture concentration of 20 percent or greater is considered "wet" and capable of <br /> supporting mold growth. Moisture content in gypsum wallboard is measured on a relative percent <br /> scale using the Delmhorst BD-2100.A moisture content of 0 to 0.4 percent is considered"dry," 0.5 to <br /> 0.9 percent is considered "borderline" and 1.0 percent and greater is considered "excess moisture" <br /> and capable of supporting mold growth. <br /> FINDINGS <br /> Visual Observations <br /> Time Observation <br /> 9:41 am Assistant Chief Brian Burkeen indicates new roof was installed at Station 11 Oct. 2014. Some <br /> other repairs have been completed and others are scheduled. <br /> 9:47 Some cracks observed on exterior stucco and interior in apparatus bay. <br /> 9:56 Dormitory drop ceiling removed. Gypsum wallboard(GWB)ceiling appears new, unpainted w/ <br /> joint compound. <br /> 10:00 Bathrooms, Men's&Women's—part of sheet vinyl floor removed at showers,est. 3' x 2'area. <br /> 10:05 Entered south attic space-wood hatch ladder with slight suspect visible growth black dots but <br /> not suspect mold growth. <br /> 10:15 Observed SVG (<2 ft2)On GWB on attic floor and A/C unit over exercise room. <br /> 10:19 Roof sheeting,trusses appear new, no SVG or water damage observed. Fiberglass batt <br /> insulation over floor GWB. Overall attic space appeared clean&free of water damage. <br /> 1 Delmhorst BD-2100. <br /> 2 Tramex Digital MRX, <br /> 5 <br /> 43 <br />
