INDIAN RIVER COUNTY JULY 25, 2014 <br />INTERGENERATIONAL RECREATION CENTER 100% CONSTRUCTION DOCUMENTS <br />3.4 FIELD CONNECTIONS <br />A. High -Strength Bolts: Install high-strength bolts according to RCSC's "Specification for Structural <br />Joints Using ASTM A 325 or A 490 Bolts" for type of bolt and type of joint specified. <br />1. Joint Type: Snug tightened <br />Weld Connections: Comply with AWS D1.1/D1.1M and AWS D1.8/D1.8M for tolerances, <br />appearances, welding procedure specifications, weld quality, and methods used in correcting <br />welding work. <br />1. Comply with AISC 303 and AISC 360 for bearing, alignment, adequacy of temporary <br />connections, and removal of paint on surfaces adjacent to field welds. <br />2. Remove backing bars or runoff tabs where indicated, back gouge, and grind steel <br />smooth. <br />3. Assemble and weld built-up sections by methods that will maintain true alignment of axes <br />without exceeding tolerances in AISC's "Code of Standard Practice for Steel Buildings <br />and Bridges" for mill material. <br />3.5 FIELD QUALITY CONTROL <br />A. Testing Agency: Owner will engage a qualified independent testing and inspecting agency to <br />inspect field welds and high-strength bolted connections. <br />B. Bolted Connections: Bolted connections will be tested and inspected according to RCSC's <br />"Specification for Structural Joints Using ASTM A 325 or A 490 Bolts." <br />C. Welded Connections: Field welds will be visually inspected according to AWS D1.1/D1.1M. <br />1. In addition to visual inspection, field welds will be tested and inspected according to <br />AWS D1.1/D1.1M and the following inspection procedures, at testing agency's option: <br />a. Liquid Penetrant Inspection: ASTM E 165. <br />b. Magnetic Particle Inspection: ASTM E 709; performed on root pass and on <br />finished weld. Cracks or zones of incomplete fusion or penetration will not be <br />accepted. <br />c. Ultrasonic Inspection: ASTM E 164. <br />d. Radiographic Inspection: ASTM E 94. <br />D. In addition to visual inspection, test and inspect field -welded shear connectors according to <br />requirements in AWS D1.1/D1.1M for stud welding and as follows: <br />1. Perform bend tests if visual inspections reveal either a less -than -continuous 360 -degree <br />flash or welding repairs to any shear connector. <br />2. Conduct tests on additional shear connectors if weld fracture occurs on shear connectors <br />already tested, according to requirements in AWS D1.1/D1.1M. <br />E. Correct deficiencies in Work that test reports and inspections indicate does not comply with the <br />Contract Documents. <br />STRUCTURAL STEEL FRAMING 051200-8 <br />
