K. Shapes and plates noted to be galvanized shall be hot-dip galvanized in compliance with <br /> ASTM A123. <br /> L. Bolts and similar threaded fasteners noted to be galvanized shall be hot-dip galvanized in <br /> compliance with ASTM A153. <br /> 2.3 SHOP QUALITY CONTROL <br /> A. Owner will select and pay for services of independent testing laboratory(ITL)to perform <br /> testing of shop full penetration welds as follows: <br /> 1. Full Penetration Welds: Test 100% of all full penetration welds exceeding 5/16 inch, <br /> using Ultrasonic Testing per AWS,D1.1 Section 6. Test 25% of all full penetration <br /> welds less than 5/16 inch,using Magnetic Particle Testing per ASTM E-109, <br /> performed on root pass and on fmished weld. (Technical II). <br /> B. Contractor will pay for services of independent testing laboratory to perform tests listed <br /> below: <br /> 1. High Strength Bolting: <br /> a. Preparation: Visually inspect mating surfaces and bolt type for all slip-critical <br /> bolted connections for general conformance with the Contract Documents prior <br /> to bolting. (Technical II). <br /> b. Slip Critical Bolts and Tension Bolts: Test bolt tightening in 10% of all bolts. <br /> Test a minimum of two bolts in each connection. Verify that all plies of <br /> connected elements have been brought into contact,at 100%of connections. <br /> Verify all tips are removed from"twist-off'bolts. (Technical II). <br /> c. Bearing Bolts: Visually inspect to confirm all plies of connected elements have <br /> been brought into contact, at 100% of connections. (Applies only to bolts <br /> designed for values not requiring exclusion of threads from failure plane,all <br /> other bolts require testings as for tension bolts.) (Technical II). <br /> 2. Shop Welding: <br /> a. Fillet Welds: Visually inspect 100% of all fillet welds for size,length and <br /> quality,per AWS D1.1. (Technical II). <br /> b. Partial Penetration Welds: Test 100% of all partial penetration welds exceeding <br /> 5/16 inch,using Ultrasonic Testing per AWS D1.1, Section 6. Test 25% of all <br /> partial penetration welds less than 5/16 inch,using Magnetic Particle Testing per <br /> ASTM E-109,performed on root pass and on finished weld. (Technical II). <br /> ADDENDUM#1 <br /> 1607.001 -ORONO ICE ARENA(CP-2) Page 05120-5 <br />
