SECTION 054000 - COLD-FORMED METAL FRAMING: continued
1.04 PERFORMANCE REQUIREMENTS:
A. Structural Performance: Provide cold-formed metal framing capable of withstanding design
loads within limits and under conditions indicated.
1. Design Loads: As indicated.
2. Deflection Limits: Design framing systems to withstand design loads without deflections
greater than the following:
a. Exterior Non-Load-Bearing Framing: Horizontal deflection of 1/600 of the wall
height where laterally supporting masonry veneer, and 1/240 of the wall height
elsewhere.
b. Roof Trusses: Vertical deflection of 1/240 of the span.
3. Design framing systems to provide for movement of framing members without damage
or overstressing, sheathing failure, connection failure, undue strain on fasteners and
anchors, or other detrimental effects when subject to a maximum ambient temperature
change of 120ºF.
4. Design framing system to maintain clearances at openings, to allow for construction
tolerances, and to accommodate live load deflection of primary building structure.
B. Cold-Formed Steel Framing, General: Design according to AISI's "Standard for Cold-Formed
Steel Framing - General Provisions."
1. Design exterior non-load-bearing wall framing to accommodate horizontal deflection
without regard for contribution of sheathing materials.
2. Roof Trusses: Design according to AISI's "Standard for Cold-Formed Steel Framing -
Truss Design."
1.05 SUBMITTALS:
A. Product Data: For each type of cold-formed metal framing product and accessory indicated.
B. LEED ® Submittals:

fraction by weight that is considered regional.
3. Product Data for Credit IEQ 4.1: For grout products installed inside the
weatherproofing barrier of the building and installed on site, submit documentation
including manufacturer's printed statement (MSDS Sheet) of VOC content of each
product.

framing; fabrication; and fastening and anchorage details, including mechanical fasteners.
Show reinforcing channels, opening framing, supplemental framing, strapping, bracing,
bridging, splices, accessories, connection details, and attachment to adjoining work.
1. For cold-formed metal framing indicated to comply with design loads, include Drawings
and structural analysis data signed and sealed by the qualified professional engineer
responsible for their preparation.
1.06 INFORMATIONAL SUBMITTALS:
A. Qualification Data: For professional engineer and testing agency.
B. Welding certificates.
