DocuSign Envelope ID: 9826C043- 4C32- 49CD- A4CC- DC28ABAB7CE7 <br />SECTION 237700 - VIBRATION AND SEISMIC CONTROLS FOR HVAC <br />PART 1 - GENERAL <br />1.1 SUMMARY <br />A. This Section includes performance requirements for delegated design of vibration and seismic controls. <br />1.2 PERFORMANCE REQUIREMENTS <br />A. Seismic - Restraint Loading: Refer to Structural Drawings for Seismic Design Category, Building Use Group, <br />and Seismic design parameters. <br />1.3 SUBMITTALS <br />A. Product Data: For all products provided. <br />B. Delegated- Design Submittal: For vibration isolation and seismic - restraint calculations and details indicated to <br />comply with performance requirements and design criteria, including analysis data signed and sealed by the <br />qualified professional engineer responsible for their preparation. <br />C. Welding certificates. <br />D. Qualification Data: For professional engineer. <br />E. Field quality - control test reports. <br />1.4 QUALITY ASSURANCE <br />A. Comply with seismic - restraint requirements in the North Carolina Building Code unless requirements in this <br />Section are more stringent. In addition to design and installation requirements in the North Carolina <br />Building Code, this contractor is responsible for furnishing all Special Inspections (as required) for <br />Seismic elements installed under this contract. <br />B. Welding: Qualify procedures and personnel according to AWS D1.1/D1.1M, "Structural Welding Code - <br />Steel." <br />C. Seismic - restraint devices shall have horizontal and vertical load testing and analysis and shall bear anchorage <br />preapproval OPA number from OSHPD, preapproved by ICC -ES, or preapproved by another agency <br />acceptable to authorities having jurisdiction, showing maximum seismic - restraint ratings. Ratings based on <br />independent testing are preferred to ratings based on calculations. If preapproved ratings are not available, <br />submittals based on independent testing are preferred. Calculations (including combining shear and tensile <br />loads) to support seismic - restraint designs must be signed and sealed by a qualified professional engineer. <br />PART 2 - PRODUCTS <br />A. Products shall be selected by engineer providing delegated design services. <br />Reece, Noland & McElrath, Inc. 237700-1 Orange County Board of Elections <br />Orange Co., NC 05/04/18 <br />
