PART	EXECUTION

EXAMINATION

Verify that floors and ceilings are level and ready to accept partitions.

Verify that facility is clean, dry, and protected from outside weather.

INSTALLATION

Comply with manufacturer's printed instructions, except where more stringent requirements are mandated by governing authorities, and except where project conditions require extra precautions or provisions.

Erect partitions plumb and square, accurately fitting to suspended ceilings and over floor coverings; adjust to correct for floor irregularities.

C.	Carpeted Floors: Use fasteners that rigidly secure partitions without damaging or defacing carpeting.

D.	Suspended Ceilings: Use fasteners that rigidly secure partitions without damaging or defacing grid or ceiling.

E.	Mechanically fasten floor track to substrate at both sides of door frames, finished ends, and other areas where additional rigidity is required.

F.	Position studs vertically in floor and ceiling tracks at frequency required by panel size; install three cross channels per stud in accordance with manufacturer's instructions.

G.	Install panel clips in accordance with manufacturer's instructions; install panels on framework, taking care to seat all panel clips on cross channels.
