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. Locate deck bundles to prevent overloading of support members.
3.3 INSTALLATION, GENERAL
