Review all available pertinent documents including design documents for the <br />original construction and renovation, investigative reports, and mechanical <br />equipment and building automation system submittals. <br />2. Develop and execute functional performance tests for the dedicated outside air unit <br />and exhaust fan(s). <br />3. Perform testing, adjusting, and balancing (TAB) measurements of exhaust air volume <br />and outside air deliver volume and measure the building pressurization relative to <br />outside air conditions. <br /> <br />Building Envelope RCx Services <br /> <br />HPBS will: <br />1. Review all available pertinent documents including design documents for the <br />original construction and renovation, investigative reports, and building envelope <br />component submittals. <br />2. Conduct a visual roof assembly inspection including coping, transitions, counter <br />flashing, and trim pieces. <br />3. Conduct a visual building envelope assessment per ASTM E 1186 guidelines including <br />building component intersections, penetrations and chases, and mechanical <br />equipment. <br />4. Perform a building pressurization (blower door) test per ASTM E 779 guidelines. <br />Where possible, an infrared camera and synthetic fog will be used to identify air <br />leakage sites. <br />5. Perform RILEM Tube Testing at two locations one each elevation of the exterior <br />block walls. The RILEM test measures the water absorption properties of the <br />waterproof sealant applied to the exterior of the building. <br />6. Perform four window water infiltration tests per AAMA 501.2 guidelines. This test <br />necessitates the removal of the interior gypsum around the window to observe <br />potential water intrusion. The County is responsible for removing and replacing <br />interior gypsum for testing. <br /> <br />Final Report <br /> <br />MBP will provide a final report consisting of our design analysis, results of functional <br />performance testing and TAB measurements, and corrective action recommendations. The <br />report will also include results of the HPBS building envelope investigation and testing including <br />documentation of air infiltration pathways and any code deficiencies in the building envelope <br />and roofing systems. HPBS will also provide recommendations to improve the building <br />envelope performance and to prevent future moisture and comfort issues. <br /> <br />Additional Services <br /> <br />DocuSign Envelope ID: 0DFBBD4D-198E-4270-BF28-A2F59EADA030
