Drawings and general provisions of the Contract, including General and Supplementary Conditions and Division 01 Specification Sections, apply to this Section. 1.2 SUMMARY A. This Section includes nonloadbearing steel fra ming members for the following applications: 1. Interior framing systems (e.g., supports for partition walls, framed soffits, furring, etc.). 1.3 SUBMITTALS A. Product Data: Furnish for each type of product used, include MSDS as applicable. 1.4 QUALITY ASSURANCE A. FireTestResponse Characteristics: For firere sistancerated assemblies that incorporate nonloadbearing steel framing, pr ovide materials and construction identical to those tested in assembly indicated according to ASTM E 119 by an independent testing agency. B. STCRated Assemblies: For STCrated assemblies, provide materials and construction identical to those tested in assembly indicated according to ASTM E 90 and classified according to ASTM E 413 by an independent testing agency. PART 2 PRODUCTS 2.1 NONLOADBEARING STEEL FRAMING, GENERAL A. Framing Members, General: Comply with ASTM C 754 for conditions indicated. 1. Steel Sheet Components: Comply with ASTM C 645 requirements for metal, unless otherwise indicated. BEARDSLEY DESIGN ASSOCIATES CORNELL NCP NON STRUCTURAL METAL FRAMING STANDARD SPECIFICATIONS 09 22 16 PAGE 2 OF 4 NOVEMBER 2, 2012 2. Protective Coating: ASTM A 653/A 653M, G40 (Z120), hotdip galvanized, unless otherwise indicated. 2.2 AUXILIARY MATERIALS A. General: Provide auxiliary materials that comply with referenced installation standards. 1. Fasteners for Metal Framing: Of type, material, size, corrosion resistance, holding power, and other properties required to fasten steel members to substrates. B. Isolation Strip at Exterior Walls: Provide one of the following: 1. AsphaltSaturated Organic Felt: ASTM D 226, Typ e I (No. 15 asphalt felt), nonperforated. 2. Foam Gasket: Adhesivebacked, closedcell vinyl foam strips that allow fastener penetration without foam displacement, 1/8 inch (3.2 mm) thick, in width to suit steel stud size. PART 3 EXECUTION 3.1 EXAMINATION A. Examine areas and substrates, with Installer present, and including welded hollowmetal frames, castin anchors, and structura l framing, for compliance with requirements and other conditions affecting performance. 1. Proceed with installation only after unsatisfactory conditions have been corrected. 3.2 INSTALLATION, GENERAL A. Installation Standard: ASTM C 754, except comply with framing sizes and spacing indicated. 1. Gypsum Board Assemblies: Also comply with requirements in ASTM C 840 that apply to framing installation. B. Install supplementary framing, and blocking to support fixtures, equipment services, heavy trim, grab bars, toilet accessories, furnishings, or similar construction. C. Install bracing at terminations in assemblies. D. Do not bridge building control and expansion joints with nonloadbearing steel framing members. Frame both sides of joints independently. BEARDSLEY DESIGN ASSOCIATES CORNELL NCP NON STRUCTURAL METAL FRAMING STANDARD SPECIFICATIONS 09 22 16 PAGE 3 OF 4 NOVEMBER 2, 2012 3.3 INSTALLING FRAMED ASSEMBLIES A. Where studs are installed directly against exterior masonry walls or dissimilar metals at exterior walls, install isolation strip between studs and exterior wall. B. Install studs so flanges within framing system point in same direction. 1. Space studs as follows: a. SingleLayer Application: 16 inches (406 mm) o.c., unless otherwise indicated. b. Multilayer Application: 16 inches (406 mm) o.c., unless otherwise indicated. C. Install tracks (runners) at floors and overhead supports. Extend framing full height to structural supports or substrates above suspended ceilings, except where partitions are indicated to terminate at suspended ceilings. Continue framing around ducts penetrating partitions above ceiling. 1. SlipType Head Joints: Where framing extends to overhead structural supports, install to produce joints at tops of framing systems that prevent axial loading of finished assemblies. 2. Door Openings: Screw vertical studs at jambs to jamb anchor clips on door frames; install runner track section (for cripple studs) at head and secure to jamb studs. a. Install two studs at each jamb, unless otherwise indicated. b. Install cripple studs at head adjacent to each jamb stud, with a minimum 1/2inch (12.7mm ) clearance from jamb stud to allow for installation of control joint in finished assembly. c. Extend jamb studs through suspended ceilings and attach to underside of overhead structure. 3. Other Framed Openings: Frame openings other than door openings the same as required for door openings, unless otherwise indicated. Install framing below sills of openings to match framing required above door heads. 4. FireResistanceRated Partitions: Install frami ng to comply with fire resistancerated assembly indicated and support clo sures and to make partitions continuous from floor to underside of solid structure. 5. SoundRated Partitions: Install framing to comp ly with soundrated assembly indicated. D. Installation Tolerance: Install each framing member so fastening surfaces vary not more than 1/8 inch (3 mm) from the plane formed by faces of adjacent framing.
