1.6 DELIVERY, STORAGE, AND HANDLING
A. Protect steel deck from corrosion, deformation, and other damage during delivery, storage and handling.
B. If ground storage is needed, store deck bundles off the ground, with one end elevated to provide drainage. Protect bundles against condensation with a ventilated waterproof covering. Stack bundles so there is no danger of tipping, sliding, rolling, shifting or material damage. Check bundles periodically for tightness, and retighten as necessary so wind cannot loosen sheets.
C. Place deck bundles on the building frame near a main supporting beam at a column or wall. Do not place bundles on unbolted frames or on unattached or unbridged joists. Ensure that the structural frame is properly braced to receive the bundles.

PART 3 EXECUTION
3.1 EXAMINATION
A. Examine support framing and field conditions for compliance with requirements for installation tolerances and other conditions affecting performance of work of this section.
3.2 PREPARATION
A. Place deck in accordance with approved placement plans.
B. Do not place deck panels on concrete support structure until concrete has cured and is dry.
C. Locate deck bundles to prevent overloading of support members.
3.3 INSTALLATION, GENERAL
A. Install deck panels and accessories according to Steel Deck Institute specifications and recommendations, and in accordance with placement plans and requirements of this section.
B. Install temporary shoring, if required, before placing deck panels.
C. Place deck panels on structural supports and adjust to final position with ends aligned. Attach firmly to the supports immediately after placement in order to form a safe working platform.
D. Cut and neatly fit deck units and accessories around openings and other work projecting through or adjacent to the decking.
E. Do not cut unscheduled openings through the deck without the approval of the Architect; reinforce openings as directed.
3.4 INSTALLATION, FORM DECK
A. Anchor deck units to steel supporting members by arc spot puddle welds of the following diameter and spacing, or fillet welds of equal strength:
1. For deck units with metal thickness equal to or greater than 0.028 inches (22 gage, 0.7 mm) use 5/8 inch (15 mm) minimum visible diameter welds with the weld pattern shown on the design drawings.
2. For deck units with metal thickness less than 0.028 inches (22 gage, 0.7 mm) weld deck through manufacturer's standard welding washers with the weld pattern shown on the Drawings.
3. Mechanical fasteners, either powder actuated or pneumatically driven, or screws may be used in lieu of welding to fasten deck to supporting framing, provided they have been specifically approved by the Architect.
4. Fasten side laps and perimeter edges of units between supports at intervals not exceeding 36 inches (1 m) on center, using one of the following methods:
a. #10 self drilling screws;
b. Crimp or button punch;
c. Arc puddle welds - 5/8 inch (15 mm) minimum visible diameter or 1 inch (25 mm) long fillet welds.
B. Install deck ends over supports with a minimum end bearing of 1.5 inches (40 mm).
C. Fasten pour stops and girder fillers to supporting structure according to manufacturer's recommendations.
D. Fasten column closures, cell closures, and Z closures to deck to provide tight fitting closures at open ends of ribs and sides of decking. Fasten cell closures at changes of direction of deck units unless otherwise directed.
3.5 REPAIRS
A. Before concrete placement, inspect deck for tears, dents, or other damage that may prevent the deck from acting as a tight and substantial form. Determine the need for the repair or temporary shoring of deck.
