Part 3: Execution
3.01 Examination
A. Examine surfaces scheduled to receive suspended units for unevenness, and irregularities that would affect quality and execution of work. Do not proceed with work until unsatisfactory conditions have been corrected.
3.02 Installation
A. Do not begin installation until sufficient materials to complete a room are received.
B. Install materials in accordance with manufacturer’s printed instructions, governing regulations, fire resistance rating requirements, and industry standards applicable to work.
C. Measure each ceiling area and establish layout of acoustical units to balance border widths at opposite edges of each ceiling. Avoid use of less-than-half width units at borders, and comply with reflected ceiling plans wherever possible.
D. Symmetrically locate grid layout in each space. Coordinate work with other trades so that lighting fixtures, grilles, and other ceiling fixtures work with grid layout.
E. Do not use universal splices or other splices which would obstruct passage of recessed lighting fixtures through grid openings or limit fixture relocation upon flanges of ceiling grids.
F. Support suspension system from structure above, not from ductwork, metal deck, equipment or piping.
G. Space hangers not more than 6 inches from ends and not more than 4 feet on center.
H. Install edge moldings at the perimeter of each ceiling area and at locations where edge of units would otherwise be exposed.
1. Secure moldings to building construction by fastening with screw anchors into substrate through holes drilled in vertical leg. Space holes no more than 3 inches from each end and not more than 16 inches on center along each molding.
2. Level moldings with ceiling suspension system, to a level tolerance of 1/8 inch in 12 feet.
3. Miter corners of moldings accurately to provide hairline joints, securely connected to pervent dislocation. Cope exposed flanges of intersecting suspension system members, so that flange faces are flush.
4. Furnish additional tees for supporting grilles, diffusers and lighting fixtures. Refer to reflected ceiling, HVAC and electrical plans for locations.
5. Provide tegular edge at walls and at other abutting vertical surfaces. Field paint cut edges to surface color and sheen.
I. Arrange units and orient directionally-patterned units, if any, in manner shown on reflected ceiling plans.
3.03 Cleaning
A. Clean exposed surfaces of ceilings, trim, edge moldings and suspension members to comply with manufacturer's instructions for cleaning and touch-up of minor finish damage.
B. Remove work which cannot be successfully cleaned and repaired to permanently eliminate evidence of damage.
3.04 Protection
A. Provide required protection for the ceilings, including dust control, so that the work will be without damage and deterioration at the time of acceptance by the Owner.
