3.3	INSTALLATION
A.	Metal Framing - General:
1.	Coordinate erection of system with appropriate sections in Division 01.
2.	Install steel framing to comply with ASTM C754 and with ASTM C840 requirements applicable to framing installation.
3.	Isolate steel framing from building structure to prevent transfer of loading imposed by structural movement at locations indicated below:
a.	Where edges of suspended ceilings abut building structure horizontally at ceiling perimeters or penetrations of structural elements.
b.	Where partitions and wall framing abuts overhead structure.
c.	slip-type joint as detailed to attain lateral support and avoid axial loading.
4.	Do not bridge building expansion and control joints with steel framing or furring members. Independently frame both sides of joints with framing or furring members.
B.	Metal Framing - Walls and Partitions:
1.	Install runners or track, at floors, ceilings and structural walls and columns where gypsum board stud system abuts other construction. Where studs are installed directly against exterior walls, install asphalt felt strips between studs and wall.
2.	Stud Spacing: Maximum 24 inches (610 mm) on center unless noted otherwise.
3.	Installation Tolerances: Install each steel framing and furring member so that fastening surfaces do not vary more than 1/8 inch (3 mm) from plane of faces of adjacent framing.
4.	Blocking: Bolt or screw steel channels to metal studs. Install concealed wood blocking for support of plumbing fixtures, toilet partitions, wall cabinets, toilet accessories, hardware and other related items requiring backing support as indicated.
5.	Standard Track and Studs: screw gypsum directly to Track and Studs starting at Floor.
6.	Versadry Track and Standard Studs: lift gypsum 2.0 inches to rest on Versadry track ledge, then screw gypsum directly to Track and Studs.
C.	Metal Framing - Suspended and Furred Ceilings:
1.	Secure hangers to structural support by connecting directly to structure where possible; otherwise connect to cast-in concrete inserts or other anchorage devices or fasteners as indicated.
a.	Do not attach hangers to metal deck tabs.
b.	Do not attach hangers to metal roof deck
c.	Do not attach hangers to underside of concrete slabs with power actuated fasteners.
2.	Install metal ceiling framing per ASTM C754, and space main runners at 4 feet (1219 mm) on center, maximum.
3.	Do not connect or suspend steel framing from ducts, pipes or conduit.
4.	Keep hangers and braces 2 inches (51 mm) clear of ducts, pipes or conduits.
5.	Sway-brace suspended steel framing with hangers used for support.
D.	Metal Framing - Shaft Wall:
1.	Anchor tabbed track perimeter framing at abutting horizontal and vertical construction.
2.	Anchor with approved fasteners spaced maximum 24 inches (610 mm) on center.
3.	Apply indicated sealant in a continuous application at the perimeter.
4.	Space CT Studs at 24 inches (610 mm) on center. Adjust the spacing at ends of shaft wall construction so end studs are minimum 8 inches from the ends.
5.	Install the first liner board panel. The panel length shall be 3/4 inch (19 mm) less than the total height of the framed section. Plumb the panel against the web of the tabbed track and bend out tabs in tabbed track to secure the panel in place.
6.	Insert a CT Stud into the top and bottom tabbed track and fit tightly over the previously installed 1 inch (25 mm) panel. Allow equal clearance between track and stud at top and bottom tabbed track. The stud length shall be 3/4 inch (19 mm) less than the total height of the framed section.
7.	Install the second 1 inch (25 mm) liner board panel inside the tabbed track and within the tabs of the CT studs.
8.	Install succeeding studs and panels in the same manner as described for the first and second panels until the wall section is complete.
9.	Anchor the final panel section at 12 inches (305 mm) on center with tabs from the tabbed track.
10.	Where wall heights exceed the standard or available length of the liner board panels, the panels shall be cut and stacked with joints occurring within the top or bottom third of the wall height. The shorter panels shall be minimum 24 inches (610 mm) long and of sufficient length to engage 2 studs.
11.	For doors, ducts or other large penetrations or openings, install jamb track as perimeter framing. Use 20 gauge track with a 3 inch (76 mm) back leg for elevator doors and block cavity. Install 12 inch wide gypsum filler strips for doors exceeding 7 ft 0 inches (2134 mm) height.
E.	Metal Framing - Area Separation Wall:
1.	Foundation: Position 2 inch (51 mm) C-runner at floor and attach securely to foundation at ends and 24 inches (610 mm) on center. Caulk under runner at foundation with minimum of 1/4 inch (6 mm) bead of acoustical sealant when specified to reduce noise transmission.
2.	First Floor: Install H-studs and insert liner board. Attach two thicknesses of 1 inch (25 mm) liner board vertically in C-runner with long edges in H-stud. Continue installing H-studs and liner board alternately until wall is complete. Attach horizontal C-runner to top of liner board, fastening flanges of C-runner at all corners on both sides of liner board with 3/8 inch (9 mm) drill point screws.
3.	Intermediate Floors: Attach C-runner to C-runner cap on wall below, staggering end joints at least 12 inches (305 mm) . Fasten C-runner together using double 3/8 inch (9 mm) screws at ends and 24 inches (610 mm) on center. Fasten H-studs to adjacent framing with aluminum breakaway clips. Attach breakaway clips to H-stud with one 3/8 inch (9 mm) drill point screw and to adjacent wood framing with 1-1/4 inch (32 mm) drywall screw. Install fire blocking between solid wall system and adjacent framing at floor lines, bottom of truss line and any other locations according to code requirements.
4.	Roof: Cut liner board and H-studs to follow roof pitch. Fasten H-studs to framing with an aluminum breakaway clip.
