PART 3    EXECUTION
3.1	EXAMINATION
A.	Do not install roof deck until supporting construction is in place.
B.	Examine support framing and field conditions for compliance with requirements for installation tolerances and other conditions affecting the performance of work of this section.
C.	If supporting construction is the responsibility of another installer, notify the architect of unsatisfactory preparation before proceeding.
3.2	PREPARATION
A.	Clean surfaces thoroughly prior to installing steel deck.
B.	Locate steel deck bundles to prevent overloading of support members.
C.	Place steel deck in accordance with approved installation drawings.
3.3	INSTALLATION
A.	Install and fasten deck and accessories in accordance with the Contract Documents, approved installation drawings, manufacturer's documented instructions, and requirements of ANSI/SDI C.
1.	Welds shall comply with AWS D1.3.
B.	Install temporary shoring, if required, before placing concrete.
C.	Place deck panels on structural supports and adjust to final position with ends aligned. Attach firmly to the supports immediately after placement 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.	Trades that subsequently cut unscheduled openings through the deck are responsible for reinforcing the openings.
F.	Reinforce steel deck openings per contract documents and approved shop drawings.
G.	End Bearing: Install deck ends over supports with a minimum end bearing of 1.5 inches. unless otherwise shown on approved installation drawings.
H.	Side Closures: Fasten to supporting structure and deck in accordance with the Contract Documents, approved installation drawings and requirements of ANSI/ SDI RD.
I.	Acoustical Batt Insulation: Supplied by the deck manufacturer and installed by the erecting contractor prior to installation of insulation.
3.4	FIELD QUALITY CONTROL
A.	Steel deck is not to be used as a working platform or storage area until units are in position and permanently attached to the structure.
B.	Construction loads are not to exceed load carrying capacity of the steel deck.
3.5	INSPECTION AND REPAIR
A.	Roof Decking: Before roof insulation placement, the deck shall be inspected for tears, dents, or other damages that will affect the structural performance of the deck.
3.6	PROTECTION
A.	Protect installed products until completion of project.
B.	Touch-up, repair, or replace damaged products before substantial completion.
