Finish: Manufacturer's standard paint applied to factory -assembled and -tested <br />equipment before shipping. <br />1. Epoxy Powder coating or electro-galvanized isolation on springs and housings. <br />Zinc plate all bolts, nuts and washers. <br />PART 3 - EXECUTION <br />3.1 EXAMINATION <br />A. Examine areas and equipment to receive vibration isolation and seismic- and wind - <br />control devices for compliance with requirements for installation tolerances and other <br />conditions affecting performance. <br />B. Examine roughing -in of reinforcement and cast -in -place anchors to verify actual locations <br />before installation. <br />C. Proceed with installation only after unsatisfactory conditions have been corrected. <br />3.2 APPLICATIONS <br />A. Multiple Pipe Supports: Secure pipes to trapeze member with clamps approved for <br />application by OSHPD. <br />B. Hanger Rod Stiffeners: Install hanger rod stiffeners where required to prevent buckling of <br />hanger rods due to seismic forces. <br />C.
