INDIAN RIVER COUNTY JULY 25, 2014 <br />INTERGENERATIONAL RECREATION CENTER 100% CONSTRUCTION DOCUMENTS <br />1. Cut, drill, or punch holes perpendicular to steel surfaces. Do not thermally cut bolt holes <br />or enlarge holes by burning. <br />2. Baseplate Holes: Cut, drill, mechanically thermal cut, or punch holes perpendicular to <br />steel surfaces. <br />3. Weld threaded nuts to framing and other specialty items indicated to receive other work. <br />2.5 SHOP CONNECTIONS <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 specified. <br />Joint Type: Snug tightened. <br />B. 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. Assemble and weld built-up sections by methods that will maintain true alignment of axes <br />without exceeding tolerances in AISC 303 for mill material. <br />2.6 SHOP PRIMING <br />A. Shop prime steel surfaces except the following: <br />1. Surfaces embedded in concrete or mortar. Extend priming of partially embedded <br />members to a depth of 2 inches. <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 (applied fireproofing). <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 />1. SSPC-SP 2, "Hand Tool Cleaning." <br />2. SSPC-SP 3, "Power Tool Cleaning." <br />3. SSPC-SP 7/NAGE No. 4, "Brush -Off Blast Cleaning." <br />4. SSPC-SP 11, "Power Tool Cleaning to Bare Metal." <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 minimum dry film thickness <br />of 1.5 mils. Use priming methods that result in full coverage of joints, corners, edges, and <br />exposed surfaces. <br />1. Stripe paint corners, crevices, bolts, welds, and sharp edges. <br />2. Apply two coats of shop paint to surfaces that are inaccessible after assembly or <br />erection. Change color of second coat to distinguish it from first. <br />PART 3 - EXECUTION <br />STRUCTURAL STEEL FRAMING 051200-6 <br />
