<br />Copyright 2001 AIA <br /> <br />MASTERSPEC Short Form <br /> <br />02/01 (R 05/06) <br /> <br />B. Shear Connectors: Prepare steel surfaces as recommended by manufacturer of shear <br />connectors. Use automatic end welding of headed-stud shear connectors according to <br />A WS D 1.1 and manufacturer's written instructions. <br /> <br />2.6 SHOP CONNECTIONS <br /> <br />A. High-Strength Bolts: Shop install high-strength bolts according to RCSC's "Specification for <br />Structural Joints Using ASTM A 325 or A 490 Bolts" for type of bolt and type of joint <br />specified. <br /> <br />1. Joint Type: [Snui~ tightened] [Pretensioned] [Slip critical]. <br /> <br />B. Weld Connections: Comply with AWS Dl.1 for welding procedure specifications, tolerances, <br />appearance, and quality of welds and for methods used in correcting welding work. <br /> <br />2.7 SHOP PRIMING <br /> <br />A. Shop prime steel surfaces except the following: <br /> <br />1. Surfaces embedded in concrete or mortar. Extend priming of partially embedded <br />members to a depth of2 inches (50 mm). <br />2. Surfaces to be field welded. <br />3. Surfaces to be high-strength bolted with slip-critical connections. <br />4. Surfaces to receive sprayed fIre-resistive materials. <br />5. Galvanized surfaces. <br /> <br />B. Surface Preparation: Clean surfaces to be painted. Remove loose rust and mill scale and <br />spatter, slag, or flux deposits. Prepare surfaces according to the following specifications and <br />standards: <br /> <br />1. SSPC-SP 2, "Hand Tool Cleaning." <br />2. SSPC-SP 3, "Power Tool Cleaning." <br /> <br />C. Priming: Immediately after surface preparation, apply primer according to manufacturer's <br />written instructions and at rate recommended by SSPC to provide a dry film thickness of not <br />less than 1.5 mils (0.038 nun). Use priming methods that result in full coverage of joints, <br />comers, edges, and exposed surfaces. <br /> <br />2.8 SOURCE QUALITY CONTROL <br /> <br />A. Owner will engage an independent testing and inspecting agency to perform shop tests and <br />inspections and prepare test reports. Comply with testing and inspection requirements of Part 3, <br />Article "Field Quality Contro1." <br /> <br />B. Correct deficiencies in Work that test reports and inspections indicate does not comply with the <br />Contract Documents. <br /> <br />C. In addition to visual inspection, shop-welded shear connectors will be tested and inspected <br />according to requirements in A WS D 1.1 for stud welding. <br /> <br />STRUCTURAL STEEL <br /> <br />05120 - 4 <br />
