SECTION 01400 <br />QUALITY CONTROL <br />A325 or A490 Bolts". <br />a) For connections using high -strength bolts installed using Load Indicating <br />Washers, the Owner's testing agency need not be present during the <br />entire installation and tightening operation, provided the Owners testing <br />agency provides the following: <br />1) Inspection of the surface and bolt type for conformance to plans and <br />specifications prior to the start of bolting. <br />2) Verification of the minimum specified bolt tensions visually and by <br />using the feeler gauge as "no go" inspection on a few bolts in each <br />connection (10 percent or two bolts, whichever is greater). <br />b) For connection using high -strength tension control bolts, the Owner's <br />testing agency need not be present during the entire installation and <br />tightening operation, provided the Testing Agency provides the <br />following: <br />1) Inspection of the surface and boll type for conformance to plans <br />and specification prior to the start of bolting. <br />2) Visual inspection of 100 percent of the high -strength bolts for <br />properly installed tension. <br />5. Miscellaneous Metal: Where miscellaneous angles, channels, studs, and <br />similar shapes are detailed for support of major components of the work, <br />the welds, bolts, and material aie subject o the same testing requirements <br />as other structural supporting members. <br />Steel Decking <br />1. General: Continuous inspection shall be provided for field attachment of all <br />steel roof and floor decking; check and verify attachment and location of all <br />closures and accessories. <br />2. Welding inspection: In addition to the specified operator qualifications, <br />prior to each welder starting work on the job and periodically as the testing <br />agency determines, each welder shall perform a weld test to demonstrate <br />to the inspector his ability to produce a satisfactory weld. The weld test <br />shall be as follows: <br />a) Weld at least two samples of deck material to a base steel section <br />simulating the framing with one weld each sample. Twist the deck <br />sample with respect to the base until failure occurs. If the decking <br />tears or if the welds shearing in torsion show the proper fusion area, <br />the welds are satisfactory. <br />b) Questionable welding of the permanent decking shall be checked by <br />the inspector by suitable means, including ultrasonic methods if <br />applicable. <br />J. Shear Stud Connectors <br />1. General: Special inspection shall be provided for the shop and field installation <br />Capital Projects Commuter Rail 01400-8 IFB No. RTA/CP 21-06 <br />Everett Station Phase 2 QUALITY CONTROL <br />
