PART 3 EXECUTION
 
3.1
EXAMINATION
A.
Before beginning installation, verify that substrate conditions previously installed under other sections are acceptable for installation of metal framing in accordance with manufacturer's installation instructions.
B.
Verify that rough-in utilities and chases are in correct locations and do not interfere with framing placement.
C.
If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
3.2
PREPARATION
A.
Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
3.3
INSTALLATION
A.
General Erection Requirements:
1.
Install cold-formed framing in accordance with requirements of ASTM C 754.
B.
Wall Framing:
1.
Erect framing and panels plumb, level and square in strict accordance with the Drawings and the approved shop drawings.
2.
Handle and lift prefabricated panels in a manner so as not to cause distortion in any member.
3.
Anchor runner track securely to the supporting structure. Install concrete anchors only after full compressive strength has been achieved.
4.
Provide a sill sealer or gasket barrier between all concrete and steel connections.
5.
Butt all track joints. Securely anchor abutting pieces of track to a common structural element, or butt-weld or splice them together.
6.
Align and plumb studs, and securely attach to the flanges or webs of both upper and lower tracks except when vertical movement is specified.
7.
Frame wall openings to include headers and supporting studs as shown in the Drawings.
8.
Coordinate erection of studs with requirements of door frames, window frames, and other similar openings.
9.
Install jack studs or cripples below window sills, above window and door heads, at freestanding stair rails and elsewhere to furnish support, securely attached to supporting members.
10.
Attach wall stud bridging in a manner to prevent stud rotation. Space bridging rows according to manufacturer's recommendations.
11.
Coordinate installation of wood bucks, anchors, and wood blocking with electrical and mechanical work to be placed within or behind stud framing.
12.
Provide temporary bracing until erection is completed.
13.
Provide stud walls at locations indicated on Drawings as "shear walls" for frame stability and lateral load resistance.
14.
Where indicated in the Drawings, provide for structural vertical movement using a vertical slide clip or other means in accordance with manufacturer's recommendations.
15.
Maintain clearance under structural building members to avoid deflection transfer to studs. Install extended leg ceiling runners.
16.
Coordinate placement of insulation in stud spaces after stud frame erection.
 
** NOTE TO SPECIFIER ** Include the following paragraphs for shaft wall construction. Delete if not required.
 
C.
Shaftwall Framing Installation:
1.
Attach runners plumb with one another, long leg on shaft side, at floor and structure overhead using power-driven fasteners located 2 inches (51mm) from each end and 24 inches (610mm) o.c. between. Cut jamb runners or studs not less than 3/8 inch (10mm) nor more than 1/2 inch (13mm) less than distance from floor to structure above. Position runners or studs at wall structural jambs. Do not attach to floor or overhead runners.
2.
With steel frame construction attach runners to beams and runners or studs to columns prior to fireproofing application. Where fireproofing is more than 1 inch (25 mm) thick, position Z-Clips at jambs no more than 4 inches (102 mm) from floor and structure above and no more than 24 inches (610 mm) o.c. between. Attach Z-Clips to steel frame with power-driven fasteners. Attach runners and studs to Z-Clips with two 1/2 inch (13 mm) type S-12 screws. Remove excess fireproofing from insides of runners and studs before installing liner boards.
3.
Cut liner boards 1 inch (25 mm) less than distance from floor to structure above; erect vertically into floor and overhead runners, and into jamb runner or stud. Where wall height exceeds maximum length of liner board, position board end joints within upper and lower 1/3 of height from floor to structure above; stagger joints in adjacent boards. Achieve tight fit at mating board ends.
4.
Cut shaftwall studs not less than 3/8 inches (10 mm) nor more than 1/2 inch (13 mm) less than distance from floor to structure above. Fit first shaftwall stud over leading edge of first liner board. Install remaining liner boards and shaftwall studs. Do not attach shaftwall Studs to runners.
5.
Do not splice shaftwall studs or studs. For wall heights exceeding 16 feet (4877 mm) attach shaftwall studs, studs, or jamb runners to floor and overhead runners with two 1/2 inch (13 mm) Type S-12 screws on shaft side and one on floor side. Fit liner boards tightly into studs or jamb runners. Fit studs or jamb runners tightly over liner boards.
6.
Corners and intersections: Position jamb runners or studs at corners and intersections.
7.
Door openings: Install studs plumb at each jamb of swinging doors. Install jamb struts plumb with long legs on shaft side at each jamb of elevator doors. Attach jamb strut studs to floor and overhead runners with two 3/8 inch (10 mm) Type S-12 screws pan head on shaft side and one on floor side. Attach strut studs to door jamb anchors with two 1/2 inch (13 mm) Type S-12 pan head screws per anchor.
8.
For walls above doors miter-cut runners legs and position runner horizontally to fit tightly between strut studs to serve as opening head. At each jamb extend runner upward into overhead runner. Attach runner webs to strut stud webs with 3/8 inch (10 mm) Type S-12 screws spaced not more than 12 inch (305 mm) oc, 2 inches (51 mm) above opening head, and not more than 4 inches (102 mm) from overhead runner, using not less than 3 screws per jamb. Install shaftwall studs horizontally at not less than 24 inches (610 mm) o.c.; attach to each mitered jamb runner oner 3/8 inch (10rmm) Type S-12 screw shaft side and one floor side.
9.
Provide additional liner boards, gypsum shims and fillers at elevator door frames as necessary to maintain fire integrity of the tested labeled frame construction. Construct opening in conformance with frame manufacturer's fire test report; secure copy of fire test report from frame manufacturer and maintain on site for elevator inspector.
10.
Small openings: Frame openings with E-Studs or J-Runners at jambs; frame heads and sills with J-Runners. Attach head and sill J-Runners to jambs with two 3/8 inch (10 mm) Type S-12 screws on shaft side and one on floor side.
11.
Do not exceed allowable stresses in shaftwall studs, studs or runners.
