PART 3 - EXECUTION
3.1 EXAMINATION
A. Examine substrates, areas, and conditions, including structural framing and substrates to which
linear plastic ceilings attach or abut, with Installer present, for compliance with requirements
specified in this and other Sections that affect ceiling installation and anchorage and with
requirements for installation tolerances and other conditions affecting performance of linear
plastic ceilings.
B. Proceed with installation only after unsatisfactory conditions have been corrected.
3.2 PREPARATION
A. Measure each ceiling area and establish layout of linear plastic strips to balance border widths
at opposite edges of each ceiling. Avoid using less-than-half-width strips at borders, and
comply with layout shown on reflected ceiling plans and on Coordination Drawings.
3.3 INSTALLATION
A. Comply with ASTM C 636/C 636M and seismic requirement indicated, per manufacturer's
written instructions and CISCA's "Ceiling Systems Handbook."
B. Suspend ceiling hangers from building's structural members 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, countersplaying, or other equally effective means.
3. Where width of ducts and other construction within ceiling plenum produces hanger
spacings that interfere with location of hangers at spacings required to support standard
suspension system members, install supplemental suspension members and hangers in
form of trapezes or equivalent devices.

4. 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 and appropriate for substrate to which
hangers are attached and for type of hanger involved.
5. Secure rod hangers to structure, including intermediate framing members, by attaching to
inserts, eye screws, or other devices that are secure and appropriate for both structure to
which hangers are attached and type of hanger involved. Install hangers in a manner
that does not cause them to deteriorate or fail due to age, corrosion, or elevated
temperatures.
6. Do not support ceilings directly from permanent metal forms or floor deck. Fasten
hangers to cast-in-place hanger inserts, postinstalled mechanical or adhesive anchors, or
power-actuated fasteners that extend through forms into concrete.
7. When steel framing does not permit installation of hanger wires at spacing required,
install carrying channels or other supplemental support for attachment of hanger wires.
8. Do not attach hangers to steel deck tabs.
9. Do not attach hangers to steel roof deck. Attach hangers to structural members.

more than 3 inches from ends, leveling with ceiling suspension system to a tolerance of
1/8 inch in 12 feet. Miter corners accurately and connect securely.
2. Do not use exposed fasteners, including pop rivets, on moldings and trim.
D. Install suspension system carriers so they are aligned and securely interlocked with one
another. Remove and replace dented, bent, or kinked members.
E. Cut linear plastic strips for accurate fit at borders and at interruptions and penetrations by other
work through ceilings.
F. Install linear plastic strips in coordination with suspension system and exposed moldings and
trim.
1. Align joints in adjacent courses to form uniform, straight joints parallel to room axis in
both directions unless otherwise indicated.
