GENERAL NOTES
A. THE ELECTRICAL CONTRACTOR SHALL COORDINATE ANY AND ALL WORK WITH OTHER TRADES
INVOLVED IN THE PROJECT, PRIOR TO THE INSTALLATION OF HIS EQUIPMENT SO AS TO AVOID
CONFLICTS DURING CONSTRUCTION AND ALLOW FOR OPTIMUM MAINTENANCE AND WORKING SPACE.
B. ALL WORK AND MATERIAL SHALL BE PROVIDED IN ACCORDANCE WITH STATE, LOCAL AND NATIONAL
CODES AND ORDINANCES.
C. EACH CONTRACTOR SHALL PROVIDE HIS OWN SUPPORT OF ALL DEVICES AND EQUIPMENT PROVIDED

B. Gypsum Board* — 5/8 in. (16 mm) thick, 4 ft (122 cm) wide with square or tapered edges. The gypsum board type, thickness, number of
layers, fastener type and sheet orientation shall be as specified in the individual U300 or U400 Series Design in the UL Fire Resistance
Directory. Max diam of opening is 32-1/4 in. (819 mm) for steel stud walls. Max diam of opening is 14-1/2 in. (368 mm) for wood stud walls.
The F and FH Ratings of the firestop system are equal to the fire rating of the wall assembly.
2. Through-Penetrants — One metallic pipe, conduit or tubing to be installed either concentrically or eccentrically within the firestop system.
The annular space shall be min 0 in. to max 2-1/4 in. (57 mm). Pipe may be installed with continuous point contact. Pipe, conduit or tubing to be
rigidly supported on both sides of wall assembly. The following types and sizes of metallic pipes, conduits or tubing may be used:
A. Steel Pipe — Nom 30 in. (762 mm) diam (or smaller) Schedule 10 (or heavier) steel pipe.
B. Iron Pipe — Nom 30 in. (762 mm) diam (or smaller) cast or ductile iron pipe.
C.Conduit — Nom 4 in. (102 mm) diam (or smaller) steel electrical metallic tubing or 6 in. (152 mm) . diam steel conduit.
D.Copper Tubing — Nom 6 in. (152 mm) diam (or smaller) Type L (or heavier) copper tubing.
E. Copper Pipe — Nom 6 in. (152 mm) diam (or smaller) regular (or heavier) copper pipe.
3. Fill, Void or Cavity Material* — Sealant — Min 5/8 in. (16 mm) thickness of fill material applied within the annulus, flush with both surfaces
of wall. At the point or continuous contact locations between pipe and wall, a min 1/2 in. (13 mm) diam bead of fill material shall be applied at the
pipe wall interface on both surfaces of wall.

3.1 EXAMINATION
A. Examine substrates, areas, and conditions, including structural framing and substrates to which acoustical tile
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 acoustical tile ceilings.
1. Proceed with installation only after unsatisfactory conditions have been corrected.
3.2 PREPARATION
A. Testing Substrates: Before installing adhesively applied tiles on wet-placed substrates such as cast-in-place
concrete or plaster, test and verify that moisture level is below tile manufacturer’s recommended limits.
B. Measure each ceiling area and establish layout of acoustical tiles to balance border widths at opposite edges of each
ceiling. Avoid using less-than-half-width tiles at borders, and comply with layout shown on reflected ceiling plans.
3.3 INSTALLATION, SUSPENDED ACOUSTICAL TILE CEILINGS
A. General: Install acoustical tile ceilings to comply with ASTM C 636 and seismic design requirements indicated, per
manufacturer’s written instructions and CISCA’s "Ceiling Systems Handbook."

ACOUSTICAL TILE CEILINGS 09 51 23 - 6
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. Splay hangers only where required and, if permitted with fire-resistance-rated ceilings, to miss obstructions;
offset resulting horizontal forces by bracing, countersplaying, or other equally effective means.
4. 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.
5. 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 and that will not deteriorate or otherwise 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.
10. Space hangers not more than 48 inches o.c. along each member supported directly from hangers, unless
otherwise indicated; provide hangers not more than 8 inches from ends of each member.
11. Size supplemental suspension members and hangers to support ceiling loads within performance limits
established by referenced standards and publications.
C. Secure bracing wires to ceiling suspension members and to supports with a minimum of four tight turns. Suspend
bracing from building’s structural members as required for hangers, without attaching to permanent metal forms,
steel deck, or steel deck tabs. Fasten bracing wires into concrete with cast-in-place or postinstalled anchors.
D. Install edge moldings and trim of type indicated at perimeter of acoustical tile ceiling area and where necessary to
conceal edges of acoustical tiles.
1. Apply acoustical sealant in a continuous ribbon concealed on back of vertical legs of moldings before they
are installed.
2. Screw attach moldings to substrate at intervals not more than 16 inches o.c. and not 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.
3. Do not use exposed fasteners, including pop rivets, on moldings and trim.
E. Install suspension system runners so they are square and securely interlocked with one another. Remove and
replace dented, bent, or kinked members.
F. Arrange directionally patterned acoustical tiles as follows:
1. Install tiles with pattern running in one direction parallel to long axis of space.
3.4 CLEANING
A. Clean exposed surfaces of acoustical tile ceilings, including trim and edge moldings. Comply with manufacturer’s
written instructions for cleaning and touchup of minor finish damage. Remove and replace tiles and other ceiling
components that cannot be successfully cleaned and repaired to permanently eliminate evidence of damage.

B Insulate all supply diffusers and ducted return grilles with 2"R6 Duct Wrap.Cut diffusers so there is a folder
2"lap on all four sides.Take with FSK tape where insulated flex meets duct insulation so there are no raw
edges of fiberglass.
C Install multiple layers of insulation with longitudinal and end seams staggered.
D Install insulation with least number of joints practical.
E Insulated Ducts Conveying Air Below Ambient Temperature:
1.Insulation on all pipes or ducts conveying air or liquids below the ambient temperature is required to
have a continuous vapor barrier.On all insulation with a vapor barrier,seal the joints,duct wrap seams,

projections with a vapor-barrier coating/mastic as specified in the individual insulation sections.
2.For insulation application where vapor barriers are indicated,extend insulation on anchor legs from
point of attachment to supported item to point of attachment to structure.Taper and seal ends at
attachment to structure with vapor-barrier coating/mastic.
3.Install insert materials and install insulation to tightly join the insert.Seal insulation to insulation
inserts with adhesive or sealing compound recommended by insulation material manufacturer.
4.Cover inserts with jacket material matching adjacent pipe insulation.Install shields over jacket,
arranged to protect jacket from tear or puncture by hanger,support,and shield.
