ST. BARBARA CATHOLIC SCHOOL TASK 2 75-24272-01 <br />DIOCESE OF ORANGE SEPTEMBER 12TH, 2024 <br />SANTA ANA, CA BID & PERMIT SET <br /> <br />METAL BUILDING SYSTEMS 133419 - 15 <br />PART 3 - EXECUTION <br />3.1 EXAMINATION <br />A. Examine substrates, areas, and conditions, with erector present, for compliance with requirements <br />for installation tolerances and other conditions affecting performance of the Work. <br />B. Before erection proceeds, survey elevations and locations of concrete- and masonry-bearing <br />surfaces and locations of anchor rods, bearing plates, and other embedments to receive structural <br />framing, with erector present, for compliance with requirements and metal building system <br />manufacturer's tolerances. <br />1. Engage land surveyor to perform surveying. <br />C. Proceed with erection only after unsatisfactory conditions have been corrected. <br />3.2 PREPARATION <br />A. Clean and prepare surfaces to be painted according to manufacturer's written instructions for each <br />particular substrate condition. <br />B. Provide temporary shores, guys, braces, and other supports during erection to keep structural <br />framing secure, plumb, and in alignment against temporary construction loads and loads equal in <br />intensity to design loads. Remove temporary supports when permanent structural framing, <br />connections, and bracing are in place unless otherwise indicated. <br />3.3 ERECTION OF STRUCTURAL FRAMING <br />A. Erect metal building system according to manufacturer's written instructions and drawings. <br />B. Do not field cut, drill, or alter structural members without written approval from metal building <br />system manufacturer's professional engineer. <br />C. Set structural framing accurately in locations and to elevations indicated, according to AISC <br />specifications referenced in this Section. Maintain structural stability of frame during erection. <br />D. Base and Bearing Plates: Clean concrete- and masonry-bearing surfaces of bond-reducing <br />materials, and roughen 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. Tighten anchor rods after supported members have been positioned and plumbed. Do not <br />remove wedges or shims but, if protruding, cut off flush with edge of plate before packing <br />with grout. <br />3. Promptly pack grout solidly between bearing surfaces and plates so no voids remain. <br />Neatly finish exposed surfaces; protect grout and allow to cure. Comply with <br />manufacturer's written installation instructions for shrinkage-resistant grouts.
