1.3 INFORMATIONAL SUBMITTALS Qualification Data: For professional engineer Welding certificates 1.4 QUALITY ASSURANCE A. Comply with seismic-restraint requirements in the IBC unless requirements in this Section are more stringent. PART 2 EXECUTION 2.1 APPLICATIONS Hanger Rod Stiffeners: Install hanger rod stiffeners where indicated or scheduled on Drawings to receive them and where required to prevent buckling of hanger rods due to seismic forces. Strength of Support and Seismic-Restraint Assemblies: Where not indicated, select sizes of components so strength will be adequate to carry present and future static and seismic loads within specified loading limits. 2.2 FIELD QUALITY CONTROL Perform tests and inspections. Provide evidence of recent calibration of test equipment by a testing agency acceptable to authorities having jurisdiction. Test to 90 percent of rated proof load of device. Remove and replace malfunctioning units and retest as specified above. Prepare test and inspection reports. 2.3 ADJUSTING Adjust isolators after piping system is at operating weight. Adjust restraints to permit free movement of equipment within normal mode of operation. VIBRATION AND SEISMIC CONTROLS FOR PLUMBING PIPING AND EQUIPMENT PART 1 GENERAL 1.1 PERFORMANCE REQUIREMENTS A. Seismic Restraint Loading: Site Class as Defined in the IBC: D.
