Cement Grout: Portland cement, ASTM C 150, Type I; and clean, natural sand, ASTM C 404. Mix at <br />ratio of 1 part cement to 2-1/2 parts sand, by volume, with minimum water required for placement and <br />hydration. <br />C. Nonmetallic, Nonshrink Grout: Premixed, nonmetallic, noncorrosive, nonstaining grout containing <br />selected silica sands, Portland cement, shrinkage-compensating agents, plasticizing and water-reducing <br />agents, complying with ASTM C 1107, with fluid consistency and a 30-minute working time. <br />PART 3 - EXECUTION <br />3.1 EXAMINATION <br />A. Examine supporting substrates and abutting structural framing for compliance with requirements, <br />including installation tolerances and other conditions affecting performance of cold-formed metal <br />framing. Do not proceed with installation until unsatisfactory conditions have been corrected. <br />3.2 INSTALLATION, GENERAL <br />A. Cold-formed metal framing may be shop or field fabricated for installation, or it may be field assembled. <br />B. Install cold-formed metal framing and accessories plumb, square, true to line, and with connections <br />securely fastened, according to manufacturer's recommendations and the requirements of this Section. <br />C. Cut framing members by sawing or shearing; do not torch cut. <br />D. Fasten cold-formed metal framing members by welding or screw fastening, as standard with fabricator. <br />Wire tying of framing members is not permitted. <br />E. Comply with AWS requirements and procedures for welding, appearance and quality of welds, and <br />methods used in correcting welding work. <br />F. Locate mechanical fasteners and install according to cold-framed metal framing manufacturer's <br />instructions with screw penetrating joined members by not less than 3 exposed screw threads. <br />G. Install framing members in one-piece lengths, unless splice connections are indicated for track or tension <br />members. <br />H. Provide temporary bracing and leave in place until framing is permanently stabilized. <br />I. Do not bridge building expansion and control joints with cold-formed metal framing. Independently <br />frame both sides of joints. <br />J. Install insulation in built-up exterior framing members, such as headers, sills, boxed joists, and double <br />studs, inaccessible upon completion of framing work. <br />K. Fasten reinforcement plate over web penetrations that exceed size of manufacturer's standard punched <br />openings. <br />L. Erection Tolerances: Install cold-formed metal framing to a maximum allowable tolerance variation from <br />plumb, level, and true to line of 1/8 inch in 10 feet (1:960) and as follows: <br />M. Space individual framing members no more than plus or minus 1/8 inch (3 mm) from plan location. <br />Cumulative error shall not exceed minimum fastening requirements of sheathing or other finishing <br />materials. <br />3.3 NONLOAD-BEARING INSTALLATION <br />A. Install continuous tracks sized to match studs. Align tracks accurately and securely anchor to supporting <br />structure as indicated. <br />B. Fasten both flanges of studs to top and bottom track, unless otherwise indicated. Space studs as follows: <br />DocuSign Envelope ID: 94E7997D-4F29-42F6-A9B4-0A160438D2A6
