<br />A. General: Comply with ASTM C 754, and ASTM C 840 requirements that apply to framing installation.
<br />B. Suspended Ceiling and Soffit Framing:
<br />1. Suspend ceiling hangers plumb and free from contact with insulation or other objects within ceiling plenum that are not part
<br />of supporting structural or ceiling suspension system. Splay hangers only where required to miss obstructions and offset
<br />resulting horizontal forces by bracing, countersplaying, or other equally effective means.
<br />2. Where width of ducts and other construction within ceiling plenum produces hanger spacings that interfere with the location
<br />of hangers required to support standard suspension system members, install supplemental suspension members and hang-
<br />ers in form of trapezes or equivalent devices. Size supplemental suspension members and hangers to support ceiling loads
<br />within performance limits established by referenced standards.
<br />3. Attach hangers to structural members. Do not support ceilings from or attach hangers to permanent metal forms, steel deck
<br />tabs, steel roof decks, ducts, pipes, or conduit.
<br />4. Screw furring to wood framing.
<br />5. Wire -tie furring channels to supports, as required to comply with requirements for assemblies indicated.
<br />6. Grid Suspension System: Attach perimeter wall track or angle where grid suspension system meets vertical surfaces.
<br />Mechanically join main beam and cross -furring members to each other and butt -cut to fit into wall track.
<br />C. Partition and Soffit Framing:
<br />1. Where studs are installed directly against exterior walls, install isolation strip between studs and wall.
<br />2. Extend partition framing full height to structural supports or substrates above suspended ceilings, except where partitions
<br />are indicated to terminate at suspended ceilings. Continue framing over frames for doors and openings and frame around
<br />ducts penetrating partitions above ceiling to provide support for gypsum board.
<br />3. Frame door openings to comply with GA-600 and with gypsum board manufacturer's applicable written recommendations,
<br />unless otherwise indicated. Screw vertical studs at jambs to jamb anchor clips on door frames; install runner track section
<br />(for cripple studs) at head and secure to jamb studs.
<br />a. Install two studs at each jamb, unless otherwise indicated.
<br />b. Extend jamb studs through suspended ceilings and attach to underside of floor or roof structure above.
<br />4. Frame openings other than door openings the same as required for door openings, unless otherwise indicated. Install fram-
<br />ing below sills of openings to match framing required above door heads.
<br />3.2 PANEL PRODUCT INSTALLATION
<br />A. Gypsum Board: Comply with ASTM C 840 and GA-216.
<br />1. Space screws a maximum of 12 inches o.c. for vertical applications.
<br />2. On ceilings, apply gypsum panels before wall/partition board application to the greatest extent possible and at right angles
<br />to framing, unless otherwise indicated.
<br />3. On partitions/walls, apply gypsum panels vertically (parallel to framing), unless otherwise indicated or required by fire -
<br />resistance -rated assembly, and minimize end joints.
<br />a. Stagger abutting end joints not less than one framing member in alternate courses of board.
<br />gg g J g
<br />e a e
<br />b. At stairwells and other high walls, install panels horizontally, unless otherwise indicated or required by fire -resis-
<br />tance -rated assembly.
<br />4. Single -Layer Fastening Methods: Apply gypsum panels to supports with steel drill screws.
<br />5. Laminating to Substrate: Comply with gypsum board manufacturer's written recommendations and temporarily brace or
<br />fasten gypsum panels until fastening adhesive has set.
<br />B. Exterior Ceilings and Soffits: Apply exterior gypsum panels perpendicular to supports, with end joints staggered and located over
<br />supports.
<br />1. Fasten with corrosion -resistant screws.
<br />3.3 FINISHING
<br />A. Installing Trim Accessories: For trim with back flanges intended for fasteners, attach to framing with same fasteners used for
<br />panels. Otherwise, attach trim according to manufacturer's written instructions.
