- 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.

- 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, FLOOR DECK
-
- A. Anchor floor deck units to steel supporting members by
- arc spot puddle welds of the following diameter and
- spacing or fillet welds of equal strength:
- 1. Weld diameter: Minimum visible 5/8 inch (15 mm).
- 2. Weld spacing: Weld edge ribs of panels at each
- support. Space additional welds an average of 12
- inches (300 mm) apart but not more than 18 inches
- (460 mm).
- 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.
- 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. End Bearing:
- 1. Install deck ends over supports with a minimum end
- bearing of 1.5 inches (40 mm).
-
- C. Pour Stops and Girder Fillers: Fasten pour stops and
- girder fillers to supporting structure according to the
- manufacturer's recommendations.
-
- D. Floor Deck Closures: 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 floor
- deck units unless otherwise directed.
-
- 3.5 REPAIRS
-
- A. Before concrete placement:
- 1. Inspect the deck for tears, dents, or other damage
- that may prevent the deck from acting as a tight and
- substantial form or that would impair structural
- capability.
- 2. Repair tears, dents, or other damage.
- 3. Obtain the approval of the Architect.
-
- B. Determine the need for temporary shoring of deck before
- concrete placement.
