PART	EXECUTION

PREPARATION

Coordinate work with related trades; scribe and cope decking for accurate fit. Allow installation of related work to avoid cutting and patching.

Select decking boards of longest possible lengths. Discard boards that are warped, twisted, bowed, crooked, or otherwise defective.

INSTALLATION

Install decking square, plumb, and level, closely fitted and securely fastened.

Use thin shanked nails with blunt points to prevent splitting.

Use 3 inch (10d) nails to fasten decking with nominal thickness of 2 inches. Use 2-1/2 inch (8d) nails to fasten decking with nominal thickness of 1-1/4 inches (31.7 mm). Length may be reduced by 1/4 inch (6.3 mm) if ring or spiral shank nails are used.

Provide one nail per joist for deck boards 2 inches (50 mm) wide, two nails per joist for deck boards 4 inches (100 mm) and wider.

Fasten deck with screws long enough to penetrate 1 inch (25 mm) into support members. Provide 1-1/2 inches (38 mm) penetration for structural components.

Secure decking with blind fastening system following manufacturer's instructions.

FIELD QUALITY CONTROL

Decking may be rejected, whether or not installed, for excessive warp, twist, bow, or crook, as well as for improper cutting or fitting.

ADJUSTING AND CLEANING

As work proceeds, maintain premises free of unnecessary accumulation of tools, equipment, surplus materials, and debris related to this work.
