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 /> 1:00 Station 1 walkthrough w/Mark Hill and Asst.
