          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.Lay out as shown in construction drawings. Secure J-Tabbed Track at perimeter framing and plumb to ceiling, floor and sides. Attach with suitable fasteners, spaced not more than 24 inches (610 mm) o.c. Apply a bead of non-hardening, flexible sealant to the perimeter.
          2.Preplan the stud layout 24 inches (610 mm) o.c. and adjust the spacing at either end so the end studs will not fall closer than 12 inches (305 mm) from the end.
          3.Erect the first 1-inch (25.4 mm) shaft wall liner panel, cut 3/4 inch (19 mm) less than the total height of the framed section. Plumb the panel against the web of the J-Tabbed Track and bend out tabs in J-Tabbed Track to secure panels in place. If tabs are not used, screw the liner panel to the J-Tabbed Track.
          4.Insert CT Shaftwall Stud, cut 3/4 inch (19 mm) less than the overall height, into the top and bottom J-Tabbed Tracks and fit tightly over the previously installed 1 inch (25.4 mm) panel. Allow equal clearance between top and bottom J-Tabbed Track.
          5.Install the next 1-inch (25.4 mm) shaft wall liner panel inside the J-Tabbed Tracks and within the tabs of the CT Shaftwall stud.
          6.Progressively install succeeding studs and panels as described above until the wall section is enclosed. The final panel section may be secured with tabs from the J-Tabbed Track at 12 inches (305 mm) o.c.
          7.Where wall heights exceed the standard or available length of shaft wall liner panels, the gypsum panels may be cut and stacked with joints occurring within the top or bottom third points of the wall. Joints of adjacent panels should be alternately staggered to prevent a continuous horizontal joint. Any butt joints must be factory edge to factory edge with pieces pushed tightly together. Gypsum panels must engage a minimum of 2 tabs of the CT Shaftwall Stud.
          8.CT Shaftwall Studs cannot be spliced. They must be installed full height, one piece. J-Tabbed Track when not attached of the structure shall not be spliced.
          9.Do not attach J-Tabbed Track to the CT Shaftwall Studs.
          10.For doors, ducts or other large penetrations or openings, install J-Tabbed Track as perimeter framing. Use 20 gauge, 0.0329 inches (0.83 mm) track with a 3 inches (76 mm) back leg for elevator doors and block cavity with 12 inches (305 mm) wide gypsum filler strips for doors exceeding 7-foot (2 m) height.
 
          D.Drywall Penetration Barrier Mesh Installation:
          1.Barrier Mesh sheets may be installed with diamond running in direction most suitable.
          2.ClarkDietrich BM-Clips shall be installed to secure the mesh to the framing members.
          3.Mesh joints occurring on framing members may either join staggered or butt together.
          4.It is acceptable to overlap mesh joints to achieve tie-in.
          5.BM sheets shall join, begin and terminate on a framing member.
          6.BM sheets not joining on framing member shall be wire tied with 18GA steel tie wire.
          7.Wire tying shall be no less frequent than the installation of Mesh Clips.
 
          3.3PROTECTION
 
          A.Protect installed products until completion of project.
 
          B.Touch-up, repair or replace damaged products before Substantial Completion.
