PART 3 - 	EXECUTION
3.1	EXAMINATION
A.	Examine substrates and structural framing to which metal panels attach or abut, with installer present, for compliance with requirements specified in this and other Sections that affect installation and anchorage, and other conditions affecting performance of metal panel ceilings.
B.	Proceed with installation only after unsatisfactory conditions have been corrected.
3.2	PREPARATION
A.	Coordination: Furnish layouts for cast-in-place anchors, clips, and other ceiling anchors whose installation is specified in other Sections. 
B.	Measure each ceiling area and establish layout of acoustical metal pan units to balance border widths at opposite edges of each ceiling. Avoid using less-than-half-width units at borders and comply with layout shown on reflected ceiling plans.
C.	Survey substrate for wall attachment to assure squareness and proper elevation for wall panel installation.
3.3	INSTALLATION
A.	General: Install metal panel ceilings, per manufacturers shop drawings provided, per manufacturer's written instructions and to comply with publications referenced below.

1.	ClSCA "Ceiling Systems Handbook"

2.	Standard for Ceiling Suspension System Installations - ASTM C 636

3.	Standard for Ceiling Suspension Systems Requiring Seismic Restraint - ASTM E 580

4.	IBC (International Building Code) Standard for Seismic Zone for local area

B.	Suspend ceiling hangers from building's approved structural substrates and as follows: 

1.	Install hangers plumb and free from contact with insulation or other objects within ceiling plenum that are not part of supporting structure or of ceiling suspension system.

2.	Splay hangers only where required to miss obstructions; offset resulting horizontal forces by bracing, counter-splaying, or other equally effective means.

3.	Where width of ducts and other construction within ceiling plenum produce hanger spacings that interfere with location of hangers at spacing required to support standard suspension system members, install supplemental suspension members and hangers in form of trapezes or equivalent devices. Utilize supplemental suspension members and hangers to support ceiling loads within performance limits established by referenced standards and publications.

4.	Where used secure wire hangers to ceiling suspension members and to supports above with a minimum of three tight turns. Connect hangers directly either to structures or to inserts, eye screws, or other devices that are secure; that are appropriate for substrate; and that will not deteriorate or otherwise fail due to age, corrosion, or elevated temperatures.

5.	Space hangers not more than 48" on-center, along each member supported directly from hangers, unless otherwise indicated; and provide hangers not more than 12" from ends of each member.

6.	Level grid to 1/8" in 10' from specified elevation(s), square and true.

7.	Adjust suspension system runners so they are square (within .5 degree from 90 degrees) and securely interlocked with one another. Remove and replace dented, bent, or kinked members.

C.	Secure bracing wires to ceiling suspension members and to supports acceptable to Architect/Engineer and/or inspector. Suspend bracing from building's structural members and/or structural deck, as required for hangers, without attaching to permanent metal forms, steel deck, or steel deck tabs (unless directed otherwise).
D.	Install edge moldings and trim of type indicated at perimeter of acoustical ceiling area and where necessary to conceal edges of acoustical metal pan. Method of edge trim attachment and design of edge trims to be approved by Architect.
E.	Scribe and cut metal panel units for accurate fit at penetrations by other work through ceilings. Stiffen edges of cut units as required to eliminate evidence of buckling or variations in flatness exceeding referenced standards for stretcher-leveled metal sheet.
F.	Install metal panel units in coordination with suspension system.

1.	Align joints in adjacent courses to form uniform, straight joints parallel to room axis in both directions, unless otherwise indicated. Install directionally patterned or textured panels in directions indicated on approved shop drawings. Panel- joints shall flow smoothly and in a straight line within 1/8" in 10'. Intersections shall be continuous.

2.	Fit adjoining units to form flush, tight joints. Scribe and cut units for accurate fit at borders and around construction penetrating ceiling.

3.	When required by the jobsite, remove protective film from panels only when space is completely clean and free of airborne particles. Use white cotton gloves for final installation of panels into grid system.
3.4	ADJUST AND CLEAN
A.	Adjust components to provide uniform tolerances.
B.	Replace all ceiling components that are scratched, dented or otherwise damaged.
C.	Clean exposed surfaces with non-solvent, non-abrasive commercial type cleaner.
3.5	CLEANING
A.	Clean exposed surfaces of suspended decorative grids, including trim and edge moldings, after removing strippable, temporary protective covering if any. Comply with manufacturer's written instructions for stripping of temporary protective covering, cleaning, and touchup of minor finish damage. Remove and replace grid components that cannot be successfully cleaned and repaired to permanently eliminate evidence of damage, including dented and deformed grids.
