Temporarily brace framing until entire integrated supporting structure has been completed and permanent connections are secured. B. Installation: 1. Install load bearing shims or grout between the underside of wall bottom track or rim track and the top of foundation wall or slab at stud locations to ensure a uniform bearing surface on supporting concrete or masonry construction. 2. Install sealer gaskets to isolate the underside of wall bottom track or rim track from the top of foundation wall or slab at stud locations. 3. Install continuous top and bottom tracks and securely anchor at corners and ends. Squarely seat studs against webs of top and bottom tracks. Space studs as indicated, set plumb, align, and fasten both flanges of studs to top and bottom tracks. a. Install and fasten horizontal bridging in stud system, spaced in rows not more than 48 inches apart. b. Isolate non-load-bearing, curtain-wall framing from building structure using vertical slide clips or deflection track designed to accommodate structural frame vertical deflection and lateral drift requirements without transferring vertical forces into framing members that are not engineered to support axial loads while providing lateral support. c. Install miscellaneous framing, components, accessories and connections to provide a complete and stable wall-framing system. 4. Tolerances: Install structural metal stud framing with a maximum variation of 1/8- inch in 10 feet, and with individual framing members no more than plus or minus 1/8-inch from plan location. Cumulative error shall not exceed minimum fastening requirements of sheathing, surfacing or other finishing materials. 5. Repair: At no cost to the Owner, repair galvanized coatings that become damaged. Comply with ASTM A 780, Annex A2 using galvanizing repair paint. END OF SECTION AWCWEST 13H02 COLD FORMED METAL FRAMING
