delivery, storage, AND HANDLING
Deliver materials to project site in original, undamaged, unopened containers bearing manufacturer's name, style, color and product number of each type of material.
Comply with manufacturer’s recommendations for storage of materials to be used in the work.
Unless otherwise required by the manufacturers of the materials, temperatures are to be maintained at 60 degrees F. or higher, and humidity at 20 to 40 percent, prior to, during and after installation.
Sequencing and Scheduling
Do not install acoustical ceilings until dust-generating activities have terminated, and above ceiling work is completed, tested and approved. Schedule installation of acoustic units after interior wet work is dry.
Upon completion of work, deliver stock of replacement materials of acoustical panels used in the work to the Projec or Construction Manager. Furnish at least ten percent [_10%_] percent or [__] panels, whichever is greater, of full-size units of each type, color and pattern of acoustical panel installed. Package extra materials in manufacturer’s standard, sealed, unopened boxes, labeled with manufacturer's name, style, number and color of unit, local distributor’s name, address and telephone number, and locations where installed in Project.
Existing suspension system shall be reused if possible and is [steel] [aluminum], approximately 1 1/2 inch (38 mm) high x [15/16 inch (8 mm)] [3/4 (18 mm)] wide, white exposed face, [ 2 by 2 feet (600 by 600 mm)] [2 by 4 feet (600 by 1200 mm)] grid, [except where light fixtures occur]. System [is] [is not] seismically braced. Any new grid system shall meet and form positive structural connection with existing system, using clips and other devices as necessary, which shall be concealed from view. Final appearance shall appear to be one continuous grid system.
Acoustical Panel (AP) MATERIALS
The suspension system and ceiling tile in the new kitchen expansion area shall match the existing kitchen area.
Certainteed VinylRock, 2 x 2 Vinyl Wrapped Smooth White Ceiling Tile.
GRID Suspension System (GS)
Suspension System shall be white heavy duty 15/16” , by Manufacturer Rockfon ---- Chicago Metallic Corp., 200 Snap
System Description: Systems shall be of steel construction as per CBC Standard 25-2 and shall consist of main and cross runners, perimeter trim, connectors, hangers and all accessories necessary for the complete installation.
All systems shall permit the installation of recessed lighting fixtures upon the flanges of the systems and any form of splice or other obstruction which would inhibit or render such installation of fixtures difficult will not be permitted.
Each intersection, splice and perimeter joint shall meet all seismic requirements of CBC Standard 25-2.
Finish: Factory finished white baked enamel over bonderized, electro-zinc-coated steel.
Main and Cross Runners:
GS 1: 15/16 inch (23 mm) flange suspension system, heavy-duty steel, grid module to suit panel size. Include 15/16 inch (23 mm) wide perimeter trim members with reveal to match that of existing commercial kitchen..
Connectors and Clips: Manufacturer's standard.
Hanger and Bracing Wires: Fed. Spec. QQ-W-461, Class 1, galvanized and annealed, 12 gage minimum.
Fasteners: Fasteners used for attachment of acoustical ceilings to building superstructure shall have an approved ICBO report.
Edge Sealer: Latex adhesive designed for the purpose of sealing field-cut edges of acoustic panels, as manufactured by Kelly-Moore, Inc., or equal.
Surfaces shall be dry and wet work completed prior to commencing installation. Inspect surfaces to receive acoustical work and report any defects. Starting work implies acceptance of surfaces and existing conditions.
<Include the following paragraph as appropriate.>
Air plenums occur above suspended ceilings in Room [____]. Verify that plenum surfaces are free of dirt, dust and loose construction soil and that construction work is otherwise complete, equipment installed and that surfaces and openings which might provide "leaks" are sealed prior to commencing installation of ceiling assembly.
Coordinate installation with other trades whose work adjoins or combines with acoustical ceilings. Unless otherwise shown, equipment, fixtures, etc., applied on or within acoustical panels are to be located symmetrically with respect to both axes. Provide grid members required to accommodate lay-in air diffusers and similar items of mechanical equipment.
Except as otherwise specified to meet structural requirements, make installation of grid systems and acoustical materials in strict accordance with approved manufacturer's specifications or recommendations and Drawing details. Where details and/or these Specifications are in apparent conflict with manufacturer's recommendations, the more stringent requirement shall apply.
Grid Suspension Systems:
Brace [new and existing] suspension to comply with CBC requirements a governing resistance to lateral forces and uplift as modified by Division 01 Section "Lateral Force Procedures".
Attachment to Building Superstructure: Install fasteners used to attach grid suspension system to building superstructure in accordance with the requirements of their approved ICBO report.
Install suspension systems in flat, level plane unless otherwise shown, joints in exposed members tight and aligned without offsets. Direction of main runners, where not specifically indicated, shall be determined by fixture layout.
Unless closer spacings are required by manufacturer of system, space hanger wires along main runners at 4 feet (1.2 m) maximum. Provide special hangers as required where items above ceiling obstruct normal hanger wires.
Provide hold-down clips for lay-in panels where required to prevent lifting and flutter caused by air pressures.
Install perimeter trim at wall and abutting vertical surfaces. Flange of trim shall be at the same level as flanges of main and cross runners.
Level suspension systems to a tolerance of 1/8 inches (3 mm) in 12 feet (3.6 m).
Unless otherwise shown on reflected ceiling plans, align grid members and tile joints parallel to perimeter walls with pattern centered in room areas both directions.
Seal field-cut panel edges of Type AP 2 panels with edge sealer.
Protect the finished installation from damage during balance of construction period. Remove any soiled or damaged items and replace with new before acceptance of Project by JKYog/Construction Mgrr,
