INDIAN RIVER COUNTY JULY 25, 2014 <br />INTERGENERATIONAL RECREATION CENTER 100% CONSTRUCTION DOCUMENTS <br />3.1 EXAMINATION <br />A. Verify, with steel Erector present, elevations of concrete- and masonry -bearing surfaces and <br />locations of anchor rods, bearing plates, and other embedments for compliance with <br />requirements. <br />1. Prepare a certified survey of bearing surfaces, anchor rods, bearing plates, and other <br />embedments showing dimensions, locations, angles, and elevations. <br />B. Proceed with installation only after unsatisfactory conditions have been corrected. <br />3.2 PREPARATION <br />A. Provide temporary shores, guys, braces, and other supports during erection to keep structural <br />steel secure, plumb, and in alignment against temporary construction loads and loads equal in <br />intensity to design loads. Remove temporary supports when permanent structural steel, <br />connections, and bracing are in place unless otherwise indicated. <br />1. Do not remove temporary shoring supporting composite deck construction until cast -in- <br />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 />Base Bearing and Leveling Plates: Clean concrete- and masonry -bearing surfaces of bond - <br />reducing materials, and roughen surfaces prior to setting plates. Clean bottom surface of <br />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 />C. Maintain erection tolerances of structural steel within AISC's "Code of Standard Practice for <br />Steel Buildings and Bridges." <br />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 that will be <br />in permanent contact with members. Perform necessary adjustments to compensate for <br />discrepancies in elevations and alignment. <br />Level and plumb individual members of structure. <br />Make allowances for difference between temperature at time of erection and mean <br />temperature when structure is completed and in service. <br />E. Splice members only where indicated. <br />F. Do not enlarge unfair holes in members by burning or using drift pins. Ream holes that must be <br />enlarged to admit bolts. <br />G. 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 />AWS D1.1/D1.1M and manufacturer's written instructions. <br />STRUCTURAL STEEL FRAMING 051200-7 <br />
