Project No. 21-1011 November 2024 054000 -6 <br /> <br />1. Spacing: Space individual framing members no more than plus or minus 1/8 inch <br />from plan location. Cumulative error shall not exceed minimum fastening <br />requirements of sheathing or other finishing materials. <br /> <br />2. Squareness: Fabricate each cold-formed metal framing assembly to a maximum <br />out of square tolerance of 1/8 inch. <br /> <br />PART 3 - EXECUTION <br /> <br />3.1 EXAMINATION <br /> <br />A. Examine supporting substrates and abutting structural framing for compliance with <br />requirements for installation tolerances and other conditions affecting performance. <br /> <br /> 1. Proceed with installation only after unsatisfactory conditions have been <br />corrected. <br /> <br />3.2 PREPARATION <br /> <br />A. Before sprayed fire-resistive materials are applied, attach continuous angles, <br />supplementary framing, or tracks to structural members indicated to receive sprayed fire- <br />resistive materials. <br /> <br />B. After applying sprayed fire-resistive materials, remove only as much of these materials as <br />needed to complete installation of cold-formed framing without reducing thickness of fire- <br />resistive materials below that are required to obtain fire-resistance rating indicated. Protect <br />remaining fire-resistive materials from damage. <br /> <br />C. Install load bearing shims or grout between the underside of wall bottom track or rim track <br />and the top of foundation wall or slab at stud or joist locations to ensure a uniform bearing <br />surface on supporting concrete or masonry construction. <br /> <br />D. Install sealer gaskets to isolate the underside of wall bottom track or rim track and the top <br />of foundation wall or slab at stud or joist locations. <br /> <br />3.3 INSTALLATION, GENERAL <br /> <br />A. Cold-formed metal framing may be shop or field fabricated for installation, or it may be <br />field assembled. <br /> <br />B. Install cold-formed metal framing according to AISI's "Standard for Cold-Formed Steel <br />Framing - General Provisions" and to manufacturer's written instructions unless more <br />stringent requirements are indicated. <br /> <br />C. Install shop- or field-fabricated, cold-formed framing and securely anchor to supporting <br />structure. <br /> <br />1. Screw, bolt, or weld wall panels at horizontal and vertical junctures to produce <br />flush, even, true-to-line joints with maximum variation in plane and true position <br />between fabricated panels not exceeding 1/16 inch. <br /> <br />D. Install cold-formed metal framing and accessories plumb, square, and true to line, and <br />with connections securely fastened. <br /> <br />1. Cut framing members by sawing or shearing; do not torch cut.
