3.2 FIELD QUALITY CONTROL <br /> A. Employ independent testing laboratory to perform inspections and tests specified herein. <br /> B. Selection of testing laboratory is subject to Architect's acceptance. <br /> C. Submit reports of inspections and test results to Architect as soon as practicable after they <br /> are made. <br /> D. Provide necessary scaffolding or temporary platforms required by testing laboratory in <br /> order to perform their work. In event steel framework is found by them to be inadequate, <br /> and such scaffolding or platforms shall comply with safety regulations and shall be <br /> acceptable to testing laboratory. <br /> E. Inspections and testing of high strength bolted connections shall consist of following: <br /> 1. Review with testing laboratory requirements and demonstrate method to be used for <br /> tightening of bolts to comply with ASTM specifications. <br /> 2. Where power wrenches or manual torque wrenches are to be used,testing laboratory <br /> shall approve procedures for calibration of wrenches and installation of bolts. <br /> 3. Enable testing laboratory to observe field installations of bolts to verify that approved <br /> procedures are being followed for bearing-type connections and that plies of <br /> connected elements have been brought into snug contact. <br /> 4. For bolts in friction-type connections,allow verification by testing laboratory that <br /> bolts in completed connections have been tightened to required tensions. <br /> a. Test minimum of 1 bolt at connections consisting of 10 bolts or less and <br /> minimum of 2 bolts,but not less than 10 percent,at connections with more than <br /> 10 bolts. <br /> b. If 1 or more bolts in connection is below required minimum tension,all bolts in <br /> that connection shall be tested,or retightened and tested again,until approved by <br /> testing laboratory. <br /> c. At connections using several bolts,return wrench to "touch up"bolts previously <br /> tightened to assure that all are tightened to prescribed amount. <br /> F. Allow testing laboratory to visually inspect field welding of steel members in accordance <br /> with Section 6, Inspection of AWS Structural Welding Code. Full penetration field welds <br /> shall be tested ultrasonically. Correct work that is not approved and inspect until welds <br /> are acceptable to laboratory. Perform such additional inspecting and work at no <br /> additional cost to Owner. <br /> ADDENDUM#1 <br /> 1607.001 -ORONO ICE ARENA(CP-2) Page 05120 -7 <br />
