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.
1.
Verify bearing elevations supporting members are correct before framing materials are installed.
2.
Select fasteners of adequate type, number, and quality to perform intended functions.
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 1007.
 
** NOTE TO SPECIFIER ** Delete references to welding connections when framing components are lighter than 16 gauge.
 
2.
Weld in compliance with AWS D.1.3.
3.
Install in compliance with applicable sections of the AISI's Standard for Cold-Formed Steel Framing General Provisions.
B.
Wall Systems:
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. Provide a sill sealer or gasket barrier between all concrete and steel connections.
4.
Butt all track joints. Securely anchor abutting pieces of track to a common structural element, or butt-weld or splice them together.
5.
Align and plumb studs, and securely attach to the flanges or webs of both upper and lower tracks except when vertical movement is specified.
6.
Frame wall openings to include headers and supporting studs as shown in the Drawings.
7.
Coordinate erection of studs with requirements of door frames, window frames, and other similar openings.
8.
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.
9.
Attach wall stud bridging in a manner to prevent stud rotation. Space bridging rows according to manufacturer's recommendations.
10.
Coordinate installation of wood bucks, anchors, and wood blocking with electrical and mechanical work to be placed within or behind stud framing.
11.
Provide temporary bracing until erection is completed.
12.
Provide stud walls at locations indicated on Drawings as "shear walls" for frame stability and lateral load resistance.
13.
Where indicated in the Drawings, provide for structural vertical movement using a vertical slide clip or other means in accordance with manufacturer's recommendations.
14.
Maintain clearance under structural building members to avoid deflection transfer to studs. Install extended leg ceiling runners.
15.
Coordinate placement of insulation in stud spaces after stud frame erection.
3.4
ERECTION TOLERANCES
 
** NOTE TO SPECIFIER ** Include erection tolerances when important to the Project. Tolerances required vary depending on nature of subsequent construction of finish. Flat, smooth surface finishes require rigid erection tolerances.
 
A.
Section 01400 - Quality Requirements: Tolerances.
B.
Maximum Variation From Indicated Position: 1/8 inch in 10 feet (3 mm in 3 m).
C.
Maximum Variation From Plumb: 1/8 inch in 10 feet (3 mm in 3 m).
 
** NOTE TO SPECIFIER ** Include the following article when a project is located in seismic resistance or high wind exposure category zones as defined by the authority having code jurisdiction; thereby requiring Special Inspections for the structural system. Coordinate this provision with any Special Inspections requirements stipulated in Section 01400 - Quality Requirements. The inspection is conducted by the Owner's Special Inspector (IBC 2000 chapter 17 and BOCA 96 chapter 17) but must be scheduled by the Contractor.
 
3.5
FIELD QUALITY CONTROL
A.
Inspection: Cooperate with Owners inspection agency for periodic special inspections required by local code authorities.
