    in this and other Sections that affect ceiling installation and anchorage and with

    requirements for installation tolerances and other conditions affecting performance of

    acoustical panel ceilings.

    B. Proceed with installation only after unsatisfactory conditions have been corrected. 3.02 PREPARATION

    A. Measure each ceiling area and establish layout of acoustical panels to balance border

    widths at opposite edges of each ceiling. Avoid using less-than-half-width panels at

    borders, and comply with layout shown on reflected ceiling plans.


    A. General: Install grid members to comply with ASTM C 636 and seismic requirements

    indicated, per manufacturer’s written instructions and CISCA’s ―Ceiling Systems


    B. Manufacturer’s reference: install in accordance with manufacturer’s current printed


    C. Drawing reference: Install in accordance with approved shop drawings and locate

    ceiling in accordance with main tee dimensions relative to elevations. D. Drop ceiling applications:

    1. Lay out ceiling area as indicated on reflected ceiling plan before any installation.

    2. Hanger wire installation: Secure hanger wires to upper structural elements and

    space hangers so that each hanger wire supports a maximum of 16 sq. ft. Lay-

    out as reflected and dimensioned in reflected ceiling plan.

    3. Space main tee members a maximum span of 48‖ on center.

    4. Space cross tees as indicated on reflected ceiling plan, usually 24‖ and/or 48‖.

    5. Install bracing wires to suspension members and to supports without attachment

    to metal formwork, steel decks or steel deck tabs.

    6. Install trim, and similar accessories as necessary and as applicable to meet

    project requirements where indicated on drawings.

    7. Install wearing soft gloves to reduce transfer of oil to finished framing members.

    8. Install mains and tees as to align joints in a straight parallel/perpendicular fashion

    as indicated on reflected ceiling plan. Fit all joints tight and flush.

    9. If cross tee’s chromate clips are to be field painted, paint after installed but before

    panel installation.

    10. If installation of grid is not wall to wall, but free style, install trim before panels.

    11. If grid is terminated at walls or not complete 24‖ modules, care should be taken

    as panels have cutting limitations.

    12. Trim WireWorks Panels and Forms Weave panels as needed with hacksaw or

    linesman’s pliers. Forms Ripple, Small Wave and Big Waves can only be cut

    parallel to the inner design wires, NOT perpendicular.

    13. Install panels by dropping down into grid frame from above.

    14. Remove all manufacturer-applied temporary protective coverings, clean and

    touchup minor finish damage. If parts were damaged, remove and replace as


    15. Upon completion, clean all exposed surfaces of decorative suspension grid

    including trims and edge molding.

    3.04 CLEANING

    A. Clean exposed surfaces of grid members and panels, 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 ceiling

    components that cannot be successfully cleaned and repaired to permanently eliminate

    evidence of damage, including dented and bent units.

    Safety First!

    Follow good safety and industrial hygiene practices during handling and installing

    of all products and systems. Take necessary precautions and wear the appropri-

    ate personal protective equipment as needed. Read material safety data sheets

    and related literature on products before specification and/or installation.
