PART 3 EXECUTION

3.1 EXAMINATION

A. Do not begin installation until substrates have been properly prepared.

B. Verify layout of hangers will not interfere with other work.

C. Verify layout conditions will not adversely affect installation.

D. If layout or substrate preparation is the responsibility of another installer, notify Architect of

09545-21

unsatisfactory preparation before proceeding.

3.2 PREPARATION

A. Clean surfaces thoroughly prior to installation.

B. Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.

3.3 INSTALLATION

A. Install in accordance with manufacturer's instructions.

B. Install suspension system in accordance with ASTM C 636 and as supplemented in this section.

C. Measure each ceiling area and establish layout of panels to balance border widths at opposite edges of each ceiling.

D. Suspend ceiling hangers from building's structural members, plumb and free from contact with insulation or other objects within ceiling plenum. Splay hangers only where required and to miss obstructions; offset resulting horizontal forces by bracing, countersplaying, or other equally effective means.

E. Where width of ducts and other construction within ceiling plenum produces hanger spacings that interfere with location of hangers, use trapezes or equivalent devices. 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.

F. Do not support ceilings directly from permanent metal forms or floor deck; anchor into concrete slabs.

G. Do not attach hangers to steel deck tabs.

H. Install edge moldings and trim of type specified at perimeter of open cell ceiling area and where necessary to conceal edges of panels. Miter corners accurately and connect securely.

I. Install suspension system runners so they are square and securely interlocked with one another. Remove and replace dented, bent, or kinked members.

J. Lay-In Panels:1. Fit panels in place, free from damaged edges or other defects detrimental to

appearance and function.2. Lay units in accordance with the approved reflected ceiling plan.3. Install units after above ceiling work is complete.4. Install units level, in uniform plane, and free from twist, warp, and dents. Press panels

from above to set into grids. Do not pull from face.

3.4 ERECTION TOLERANCES

A. Maximum Variation from Flat and Level Surface: 1/8 inch in 10 feet (3 mm in 3 m).

B. Maximum Variation from Plumb of Grid Members Caused by Eccentric Loads: 2 degrees.

3.5 PROTECTION AND CLEANING

A. Protect installed products until completion of project.

09545-22

B. Clean adjacent surfaces and remove unused materials and debris from site.

C. Clean panels by vacuuming, brushing, or washing with water. Allow panels to dry after washing, before replacing.

D. Remove and reinstall improperly installed material.

E. Remove damaged ceiling panels, replace with undamaged ceiling panels.

F. Touch-up, repair or replace damaged products before Substantial Completion.
