          PART 3EXECUTION
 
          3.1EXAMINATION
 
          A.Prior to installation, inspect previous work of all other trades. Verify that all work is complete and accurate to the point where this installation may properly proceed in strict accordance with framing shop drawings.
 
          B.If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
 
          3.2ERECTION
 
          A.Install cold-formed framing in accordance with requirements of ASTM C 754.
          ** NOTE TO SPECIFIER ** Delete references to welding connections when framing components are lighter than 16 gauge.
 
          B.Framing Installation:
          1.Erect framing and panels plumb, level and square in strict accordance with approved drawings.
          2.Handle and lift prefabricated panels in a manner to not 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.Butt all track joints. Securely anchor abutting pieces of track to a common structural element, or splice them together.
          5.Align and plumb studs, and securely attach to the flanges or webs of both upper and lower tracks.
          6.Attach wall stud bridging when required in a manner to prevent stud rotation. Space bridging rows according to manufacturer's recommendations.
          7.Provided temporary bracing until erection is completed.
          8.Where indicated in the drawings, provide for structural vertical movement using means in accordance with manufacturer's recommendations.
          9.Cut all framing components square for attachment to perpendicular members or as required for an angular fit against abutting members.
          ** NOTE TO SPECIFIER ** Provide the following for shaft wall construction.
 
          C.Shaftwall Framing Installation:
          1.Attach J-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 J-Runners or E-Studs not less than 3/8 inch (10mm) nor more than 1/2 inch (13mm) less than distance from floor to structure above. Position J-Runners or E-Studs at wall structural jambs. Do not attach to floor or overhead J-Runners.
          2.With steel frame construction attach J-Runners to beams and J-Runners or E-Studs to columns prior to fireproofing application. Where fireproofing is more than 1 in. thick, position Z-Clips at jambs no more than 4 inches (102mm) from floor and structure above and no more than 24 inches (610mm) o.c. between. Attach Z-Clips to steel frame with power-driven fasteners. Attach J-Runners and E-Studs to Z-Clips with two (2) 1/2 inch (13mm) type S-12 screws. Remove excess fireproofing from insides of J-Runners and E-Studs before installing liner boards.
          3.Cut liner boards 1 inch (25mm) less than distance from floor to structure above; erect vertically into floor and overhead J-Runners, and into jamb J-Runner or E-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 (10mm) nor more than 1/2 inch (13mm) 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 J-Runners.
          5.Do not splice Shaftwall Studs or E-Studs. For wall heights exceeding 16 feet (4877mm) attach shaftwall studs, E-Studs, or jamb J-runners to floor and overhead J-Runners with two (2) 1/2 inch (13mm) Type S-12 screws on shaft side and one (1) on floor side. Always fit liner boards tightly into studs or jamb runners. Always fit studs or jamb runners tightly over liner boards.
          6.Corners and intersections: Position jamb J-Runners or E-Studs at corners and T-intersections.
          7.Door openings: Install E-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 J-Runners with two (2) 3/8 in (10mm) Type S-12 screws pan head on shaft side and one (1) on floor side. Attach strut studs to door jamb anchors with two (2) 1/2 inch (13mm) Type S-12 pan head screws per anchor.
          8.For walls above doors miter-cut J-Runners legs and position J-Runner horizontally to fit tightly between strut studs to serve as opening head. At each jamb extend J-Runner upward into overhead J-Runner. Attach J-Runner webs to strut stud webs with 3/8 inch (10mm) Type S-12 screws spaced not more than 12 inch (305mm) oc, 2 inches (51mm) above opening head, and not more than 4 inches (102mm) from overhead J-Runner, using not less than 3 screws per jamb. Install Shaftwall Studs horizontally at not less than 24 inches (610mm) o.c.; attach to each mitered jamb J-Runner one (1) 3/8 inch (10mm) Type S-12 screw shaft side and one (1) 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 (2) 3/8 inch (10mm) Type S-12 screws on shaft side and one (1) on floor side.
          11.Do not exceed allowable stresses in Shaftwall Studs, E-studs or J-Runners.
 
          3.3PROTECTION
 
          A.Protect installed products until completion of project.
 
          B.Touch-up, repair or replace damaged products before Substantial Completion.
