Orange County Architectural Renovations Smith Sinnett / 2023036 <br />Hillsborough, NC Orange County Asset Management Services <br />HYDRAULIC ELEVATORS 14 24 00 - 11 <br />PART 3 - EXECUTION <br />3.1 EXAMINATION <br />A. Examine elevator areas, with Installer present, for compliance with requirements for installation tolerances and other <br />conditions affecting performance. Verify critical dimensions and examine supporting structure and other conditions <br />under which elevator work is to be installed. <br />1. For the record, prepare a written report, endorsed by Installer, listing dimensional discrepancies and <br />conditions detrimental to performance or indicating that dimensions and conditions were found to be <br />satisfactory. <br />2. Proceed with installation only after unsatisfactory conditions have been corrected. <br />3.2 INSTALLATION <br />A. Install cylinder plumb and accurately centered for elevator car position and travel. Anchor securely in place, <br />supported at pit floor and braced at intervals as needed to maintain alignment. Anchor cylinder guides at spacing <br />needed to maintain alignment and avoid overstressing guides. <br />B. Welded Construction: Provide welded connections for installing elevator work where bolted connections are not <br />required for subsequent removal or for normal operation, adjustment, inspection, maintenance, and replacement of <br />worn parts. Comply with AWS standards for workmanship and for qualifications of welding operators. <br />C. Sound Isolation: Mount rotating and vibrating equipment on vibration-isolating mounts designed to effectively <br />prevent transmission of vibrations to structure and thereby eliminate sources of structure-borne noise from elevator <br />system. <br />D. Install piping above the floor, where possible. Where not possible, install underground piping in Schedule 40 PVC <br />pipe casing assembled with solvent-cemented fittings. <br />E. Lubricate operating parts of systems as recommended by manufacturers. <br />F. Alignment: Coordinate installation of hoistway entrances with installation of elevator guide rails for accurate <br />alignment of entrances with car. Where possible, delay installation of sills and frames until car is operable in shaft. <br />Reduce clearances to minimum, safe, workable dimension at each landing. <br />G. Leveling Tolerance: 1/4 inch, up or down, regardless of load and direction of travel. <br />H. Set sills flush with finished floor surface at landing. Fill space under sill solidly with nonshrink, nonmetallic grout. <br />I. Locate hall signal equipment for elevators as follows, unless otherwise indicated: <br />1. For groups of elevators, locate hall push-button stations between two elevators at center of group or at <br />location most convenient for approaching passengers. <br />3.3 FIELD QUALITY CONTROL <br />A. Acceptance Testing: On completion of elevator installation and before permitting use (either temporary or <br />permanent) of elevators, perform acceptance tests as required and recommended by ASME A17.1 and by governing <br />regulations and agencies. <br />B. Advise Owner, Architect, and authorities having jurisdiction in advance of dates and times tests are to be performed <br />on elevators. <br />C. Make necessary adjustments of operating devices and equipment to ensure elevator operates smoothly and accurately. <br />3.4 CLEANING <br />A. Before final acceptance, remove protection from finished surfaces and clean and polish surfaces in accordance with <br />manufacturer’s recommendations for type of material and finish provided.
