City of Santa Ana Public Library Renovation <br /> Group 4 Architecture Research + Planning, Inc. <br />RFI #121 – April 16, 2025 Group 4 Project No. 22575-01 <br /> <br /> <br />10 2226-8 OPERABLE PARTITIONS <br />PART 3 - EXECUTION <br />3.1 EXAMINATION <br />A. Examine flooring, structural support, and opening, with installer present, for compliance with <br />requirements for installation tolerances and other conditions affecting performance of <br />operable panel partitions. <br />B. Proceed with installation only after unsatisfactory conditions have been corrected. <br />3.2 INSTALLATION <br />A. General: Comply with ASTM E557 except as otherwise required by operable panel partition <br />manufacturer's written installation instructions. <br />B. Install operable panel partitions and accessories after other finishing operations, including <br />painting, have been completed. <br />C. Install panels from marked packages in numbered sequence indicated on Shop Drawings. <br />D. Broken, cracked, chipped, deformed, or unmatched panels are not acceptable. <br />E. Broken, cracked, deformed, or unmatched gasketing or gasketing with gaps at butted ends <br />is not acceptable. <br />3.3 FIELD QUALITY CONTROL <br />A. Optional Testing: City reserves the right to field sound test partition installation within 60 days <br />of installation. City Representative shall engage a qualified, professional, acoustical engineer <br />to perform field tests and to prepare test reports. Cost of the field sound tests shall be <br />responsibility of the City. <br />B. Testing Methodology: Perform testing of installed operable panel partition for noise isolation <br />according to ASTM E336, determined by ASTM E413, and rated for not less than STC <br />indicated. Adjust and fit partitions to comply with STC test method requirements. <br />C. Repair or replace operable panel partitions that do not comply with requirements. <br />1. Should operable panel partitions fail to achieve the specified STC, partition supplier <br />shall make corrections/adjustments and pay for the cost of retesting. <br />2. In the event that the specified STC is not achieved after corrections/adjustments and <br />retesting and the partition supplier has not been able to demonstrate that flanking <br />sound through the surrounding building construction is the cause for failure then the <br />partition supplier, at its own cost, shall replace the operable partition with a new <br />partition that is capable of achieving the specified STC and pay for the cost of field <br />sound testing this partition installation. <br />D. Prepare written test and inspection reports and submit to the City Representative. <br />3.4 ADJUSTING <br />A. Adjust operable panel partitions to operate smoothly, easily, and quietly, free from binding, <br />warp, excessive deflection, distortion, nonalignment, misplacement, disruption, or <br />malfunctioning, throughout entire operational range. Lubricate hardware and other moving <br />parts as indicated by wall manufacturer.
