' 40-27 BUILDING <br />STRUCTURAL STEEL FRAMING <br />F <br />1 <br />1� <br />BRPH ARCHITECTS -ENGINEERS, INC. <br />3.2 PREPARATION <br />A. Provide temporary shores, guys, braces, and other supports during erection to keep <br />structural steel secure, plumb, and in alignment against temporary construction loads <br />and loads equal in intensity to design loads. Remove temporary supports when <br />permanent structural steel, connections, and bracing are in place unless otherwise <br />indicated. <br />Do not remove temporary shoring supporting composite deck construction until <br />cast -in -place concrete has attained its design compressive strength. <br />3.3 ERECTION <br />A. Set structural steel accurately in locations and to elevations indicated and according to <br />AISC 303 and AISC 360. <br />B. Baseplates: Clean concrete- surfaces of bond -reducing materials, and roughen <br />surfaces prior to setting plates. Clean bottom surface of plates. <br />1. Set plates for structural members on wedges, shims, or setting nuts as required. <br />2. Weld plate washers to top of baseplate. <br />3. Snug -tighten anchor rods after supported members have been positioned and <br />plumbed. Do not remove wedges or shims but, if protruding, cut off flush with <br />edge of plate before packing with grout. <br />4. Promptly pack grout solidly between bearing surfaces and plates so no voids <br />remain. Neatly finish exposed surfaces; protect grout and allow to cure. Comply <br />with manufacturer's written installation instructions for shrinkage -resistant grouts. <br />C. Maintain erection tolerances of structural steel within AISC 303, "Code of Standard <br />Practice for Steel Buildings and Bridges." <br />D. Align and adjust various members that form part of complete frame or structure before <br />permanently fastening. Before assembly, clean bearing surfaces and other surfaces <br />that are in permanent contact with members. Perform necessary adjustments to <br />compensate for discrepancies in elevations and alignment. <br />1. Level and plumb individual members of structure. <br />2. Make allowances for difference between temperature at time of erection and <br />mean temperature when structure is completed and in service. <br />E. Splice members only where indicated. <br />F. Do not use thermal cutting during erection unless approved by Engineer. Finish <br />thermally cut sections within smoothness limits in AWS D1.101.1M. <br />G. Do not enlarge unfair holes in members by burning or using drift pins. Ream holes that <br />must be enlarged to admit bolts. <br />C06922.001.00 05 12 00 - 9 <br />05-22-14 <br />
