Use deck designed in accordance with specifications for "North American Specification for the Design of Cold -Formed Steel Structural Members" prepared and published by American Iron and Steel Institute; and in compliance with SDI Design Manual, Publication No. 31 prepared and published by Steel Deck Institute. 2. Form deck units in lengths to span three or more supports, with flush, telescoped, or nested 2 -inch laps at ends and interlocking or nested side laps, of metal thickness, depth, and width as indicated. a. Nominal height: Fluted profile, see Structural Drawings for specific deck profiles. b. Formed sheet width: 24 or 36 inches see Drawings for specific deck profiles; 12 inches for deep deck type. B. Steel Roof Deck: Provide roof deck or acoustical roof deck to comply with this specification and structural drawings. C. Metal Closure Strips: Fabricate metal closure strips, for cell raceways and openings between decking and other construction, of not less than 0.045 -inch min. (18 gage) sheet steel or to match adjacent decking gage, whichever is heavier. Include cover plates required to cover gaps where deck units abut or change direction, around columns, to cover access holes used for welding, and closures where required. Form to provide tight -fitting closures at open ends of cells or flutes and sides of decking. PART 3 - EXECUTION 3.01 INSPECTION A.
