<br />Copyright 2001 AIA <br /> <br />MASTERSPEC Short Form <br /> <br />02/01 (R 05106) <br /> <br />PART 3 - EXECUTION <br /> <br />3.1 ERECTION <br /> <br />A. Examination: Verify elevations of concrete- and masonry-bearing surfaces and locations of <br />anchor rods, bearing plates, and other embedments, with steel erector present, for compliance <br />with requirements. <br /> <br />1. Proceed with installation only after unsatisfactory conditions have been corrected. <br /> <br />B. Set structural steel accurately in locations and to elevations indicated and according to AISC's <br />"Code of Standard Practice for Steel Buildings and Bridges" and "[Specification for Structural <br />Steel Buildings--Allowable Stress Design and Plastic Design] [Load and Resistance Factor <br />Design Specification for Structural Steel Buildings]." <br /> <br />C. Base[ and Bearing] Plates: Clean concrete- and masonry-bearing surfaces of bond-reducing <br />materials, and roughen surfaces prior to setting baser and hearing] plates. Clean bottom <br />surface ofbase[ and hearing] plates. <br /> <br />1. Set baser and hearing] plates for structural members on wedges, shims, or setting nuts as <br />required. <br />2. Weld plate washers to top of base plate. <br />3. [Snug-tighten] [pretension] anchor rods after supported members have been positioned <br />and plumbed. Do not remove wedges or shims but, if protruding, cut off flush with edge <br />of baser or bearing] plate before packing with grout. <br />4. Promptly pack grout solidly between bearing surfaces and baser or hearing] plates so no <br />voids remain. Neatly finish exposed surfaces; protect grout and allow to cure.[ Comply <br />with manufacturer's written installation instructions for shrinkage-resistant grouts.] <br /> <br />D. Maintain erection tolerances of structural steel within AISC's "Code of Standard Practice for <br />Steel Buildings and Bridges." <br /> <br />3.2 FIELD CONNECTIONS <br /> <br />A. High-Strength Bolts: 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: [Snug tightened] [Pretensioned] [Slip critical]. <br /> <br />B. Weld Connections: Comply with AWS D1.1 for welding procedure specifications, tolerances, <br />appearance, and quality of welds and for methods used in correcting welding work. <br /> <br />1. Comply with AISC's "Code of Standard Practice for Steel Buildings and Bridges" and <br />"[Specification for Structural Steel Buildings-Allowahle Stress Design and Plastic <br />Design] [Load and Resistance Factor Design Specification for Structural Steet <br />Buildings]" for bearing, adequacy of temporary connections, alignment, and removal of <br />paint on surfaces adjacent to field welds. <br /> <br />STRUCTURAL STEEL <br /> <br />05120 - 5 <br />
