../Word/01%2033%2029.doc

../Word/01%2033%2029.doc

../Word/01%2033%2000.doc



Deliver manufactured materials in the manufacturers' original unbroken

packages or containers which are labeled plainly with the manufacturers'

names and brands. Keep cementitious materials dry and stored off the

ground, under cover, and away from sweating walls and other damp surfaces

until ready for use. Keep materials wrapped and separate from off-gassing

materials, such as paints and adhesives. Do not use materials that have

visible moisture or biological growth.

1.5 GYPSUM PLASTER FULL SIZE SAMPLE

After selection of an acceptable texture, construct a sample [panel] [wall]

separate from the building, minimum size of [2400] [_____] mm ([8] [_____]

ft)in height, by [2400] [_____] mm ([8] [_____] ft) in length, using 150

mm(6 inch) metal studs, and gypsum board, metal lath and gypsum plaster.

The sample wall must show all aspects of gypsum plaster work, including but

not limited to, expansion joints, control joints, corner extrusions,[

[electrical][ mechanical][ and][ fire sprinkler] penetration[s]] and casing

beads. A sample of a control joint and extrusion butt joint must also be

incorporated into the sample wall. Finish work must match the approved

sample panel.[ Divide the panel into four equal quadrants with the

expansion and control joints to show each phase of work, lath, scratch coat,

brown coat, and finish coats.] Provide and protect the sample wall from

damage during the length of the contract.

1.6 SCHEDULING AND ENVIRONMENTAL REQUIREMENTS

Commence application only after the area scheduled for gypsum plastering

work is completely weathertight. The heating, ventilating, and air-

conditioning systems must be complete and in operation prior to application

of the plaster. If the mechanical system cannot be activated before veneer

plastering is begun, the plastering may proceed in accordance with an

approved plan to maintain the environmental requirements specified below.

Apply plaster prior to the installation of finish flooring and acoustic

ceiling.

1.6.1 Environmental Requirements

***************************************************************************

NOTE: Gypsum plaster is a very thin coating that

will be adversely affected by extreme of non-uniform

drying conditions and by rapid changes in

temperature. It should not be used in spaces where

adequate environmental control cannot be obtained.

***************************************************************************

Do not expose the gypsum base to excessive sunlight prior to plaster

application, as bond failure of the plaster may result. Maintain a

continuous uniform temperature of not less than 10 degrees C (50 degrees F)

and not more than 27 degrees C (80 degrees F) for at least one week prior to

the application of veneer plaster, while the plastering is being done, and

for at least one week after the plaster is set. Shield air supply and

distribution devices to prevent any uneven flow of air across the plastered

surfaces. Provide ventilation to exhaust moist air to the outside during

plaster application, set, and until plaster is dry. In glazed areas, keep

windows open top and bottom or side to side 75 to 100 mm (3 to 4 inches).

Openings can be reduced in cold weather. For enclosed areas lacking natural

ventilation, provide temporary mechanical means for ventilation. In



unglazed areas subjected to hot, dry winds or temperature differentials from

day to night of 10 degrees C (20 degrees F) or more, screen openings with

cheesecloth or similar materials. Avoid rapid drying. During periods of

low indoor humidity, provide minimum air circulation following plastering

and until plaster is dry.

[1.7 FIRE RESISTIVE COATINGS

***************************************************************************

NOTE: For fire-resistive assemblies, drawing details

must follow the tested and approved designs. The

addition of gypsum plaster to an approved gypsum

wallboard design will improve the fire-resistive

properties of the partitions. Tested and approved

designs are published by gypsum wallboard

manufacturers, Underwriters Laboratory, and Factory

Mutual, and are included in the Gypsum Association

Fire Resistance Design Manual.

***************************************************************************

Comply with specified fire-rated assemblies for design numbers indicated per

UL Fire Resistance or FM APP GUIDE.

loose sand must contain a minimum of 36 kg (80 lb) of dry sand in 0.0283 cu

m (one cu ft).

2.8.1.3 Mixing (Do's)

Mix the material while the mixer is in continuous operation in the following

sequence:

a. Add maximum close to 90 percent of estimated quantity of water.

b. Add approximately one-half of the sand. If vermiculite or perlite is

used, add all the aggregate.

c. Add cement and approved admixtures. [Add lime prior to cement.]

d. Add remainder of sand.

e. Mix with remainder of water as required. Mix until the mixture is

uniform in color and consistency.

2.8.1.4 Mixing (Don'ts)

Avoid excessive mixing and agitation. Discard gypsum plaster which has begun

printed instructions.

2.9 BONDING AGENT

***************************************************************************

NOTE: Bonding agents may be surface applied or

integrally mixed with the plaster. Use Integral

bonding agents only after review of the

manufacturer's documentation of testing and past

performance. Check compatibility of the bonding

agent with the plaster mixtures. Bonding admixtures

increase the potential for shrinkage of the plaster.

ASTM C631, interior application.

PART 3 EXECUTION



3.1 SURFACE PREPARATION

Clean surfaces before application of gypsum plaster of projections, dust,

loose particles, grease, bond breakers, and foreign matter. Do not apply

plaster directly to surfaces (1) of masonry or concrete that have been

coated with bituminous compound or other waterproofing agents, or (2) that

have been painted or previously plastered. Before plaster work is started,

wet masonry and concrete surfaces thoroughly with a fine fog spray of clean

water to produce a uniformly moist condition. Check metal grounds, corner

beads, screeds, and other accessories carefully for alignment before

starting work. Do not apply gypsum plaster to surfaces containing frost.

3.2 WORKMANSHIP

3.2.1 Slump Tests

Apply Plaster by hand or machine. When a plastering machine is used,

control the fluidity of gypsum plaster to have a slump of not more than 75

mm (3 inch) when tested using a 50 by 100 by 150 mm (2 by 4 by 6 inch) high

slump cone. Subsequent to determining water content to meet the specified

slump, do not add additional water to the mix. Conduct the slump test

according to the following procedure:

a. Place cone on level, dry, non-absorptive base plate.

b. While holding cone firmly against base plate, fill cone with plaster

taken directly from the hose or nozzle of the plastering machine,

tamping with metal rod during filling to release air bubbles.

c. Screed off plaster level with top of cone. Remove cone by lifting it

straight up with a slow and smooth motion.

d. Place cone in a vertical position adjacent to freed plaster sample,

using care not to shake or move base plate.

e. Lay a straightedge across top of cone, being careful not to shake or

move cone. Measure slump in mm (inch) from the bottom edge of the

straightedge to the top of the slumped plaster sample.

3.2.2 Application

Apply gypsum plaster in three coats, except as follows:

Gypsum plaster applied to [masonry] [and] [gypsum lath] using the two-

coat double-up method.

Apply base coats with sufficient pressure and ensure plaster is sufficiently

plastic to provide a strong bond to bases. Work base coats into screeds at

intervals from 1500 to 2400 mm (5 to 8 ft). Plaster must not be continuous

across expansion and control joints occurring in walls, partitions, and

ceilings. Finish work level, plumb, square, and true, within a tolerance of

3 mm in 2400 mm (1/8 inch in 8 ft), without waves, cracks, blisters, pits,

crazing, discoloration, projections, or other imperfections. Form plaster

work carefully around angles and contours, and well-up to screeds. Take

special care to prevent sagging and consequent dropping of applications.

There must be no visible junction marks in finish coat where one day's work

adjoins another.[ Plastered surfaces to receive[ rubber or vinyl base



coves][ wood base boards] must extend to wood ground indicated as backing

for base.] Plaster not required behind built-in cabinets and equipment[,

and [_____]] unless part of a fire-rated assembly.

3.2.3 Control And Expansion Joints

[Install control joints at locations indicated before applying gypsum

plaster. Vertical joints must be continuous and butt horizontal joints

against the vertical joints. ]Check expansion, control joints and

accessories to ensure unrestrained movement, metal lath not continuous

behind the joints, and area between joints do not exceed 14 sq m (150 sq

ft).

3.2.4 Curing

3.2.4.1 Gypsum Plaster

Before the plaster has set, provide environmental controls to prevent the

plaster from drying too fast. After the plaster has set, provide for rapid

drying to develop high strength.

3.3 GYPSUM PLASTER WORK

ASTM C842.

***************************************************************************

NOTE: Gypsum basecoat plaster may be by one of two

methods for a three-coat or two-coat (double back)

systems. The three-coat plaster system will require

a basecoat of a scratch coat, cross raked, partial

drying, and a brown coat. The two-coat plaster system

requires a scratch coat and a brown coat that is

applied (double back) within a few minutes to the

unset (moist) scratch coat. The cross raking of the

scratch coat is omitted in the double back system.

***************************************************************************

3.3.1 Gypsum Plaster Thickness Requirements

Plaster thicknesses are from face of metal lath plaster base (scratch coat)

or solid base surfaces.

a. Vertical Surfaces

Base Types Base Coat Finish Coat Total Thickness

inch).

c. Where vertical and horizontal concrete surfaces require more than 16 mm

(5/8 inch) and 10 mm (3/8 inch), to produce required lines or surfaces,

[attach metal plaster base for plaster application] [as indicated].

3.3.2 Gypsum Plaster Basecoat Work

3.3.2.1 Gypsum Two-Coat System

Apply the first coat to cover the base with sufficient material and pressure

to form a good bond on the wall or ceiling base. Before the first coat has

set and without scratching or cracking the surface, apply a second coat

(double back) of the same material proportion as the base coat to the

screeds. Straighten to a true surface without application of water, and

cross rake or scratch to receive the finish coat.

3.3.2.2 Gypsum Three-Coat System

Apply scratch coat 5 to 6 mm (3/16 to 1/4 inch) thick to cover the base with

sufficient material and pressure to form a good bond on the wall or ceiling

base. Rake or scratch the surface and allow to set firm and hard. Apply

the brown coat to bring the base coat out to the screeds, compact and

straighten to a true surface without the application of water, and cross

rake or scratch to receive the finish coat.

3.3.3 Gypsum Plaster Finish Coats

***************************************************************************

NOTE: Do not specify rough textured finishes

bathrooms, kitchens, and other similar type places,

which require a constant cleaning cycle.

***************************************************************************

***************************************************************************

NOTE: There are six gypsum finish coat plasters,

each with a specific function:

Smooth Finishes: Gypsum-lime putty trowel finish

Keene's cement-lime putty trowel finish Prepared

gypsum trowel finish

Float Finishes: Keene's cement-lime sand float

finish Gypsum-sand float finish

Acoustical Plaster Finishes

***************************************************************************

Moderately moisten or fog spray base coat of plaster that has become dry

before finish coat is applied. Accelerate plaster, if necessary, to provide

a setting time of not more than 4 hours from the time the plaster is mixed.

3.3.3.1 Lime-Putty and Gypsum-Gauged Finish Coats



Apply lime-putty gypsum-gauged finish white coat or aggregated white coat

[and high strength gypsum gauged finish] over the base coat, scratch in

thoroughly, lay on well, double back, and fill out to a true, even surface.

Allow the finish to dry a few minutes, then trowel well with water. Apply

maximum pressure in order to compact the finish coat and provide a smooth

finish free from blemishes and irregularities. Apply trowel finish coats of

gypsum-gauged lime-putty over properly prepared base coats as thin as

possible and 2 to 3 mm (1/16 to 1/8 inch) thick for conventional plaster

system, except as necessary in spots to level out hollows in base coat.

3.3.3.2 Keene's Cement Lime-Putty Finish Coat

***************************************************************************

NOTE: Do not use Keene's cement as finish coat over

a portland cement plaster basecoat, or on monolithic

concrete, due to the probability of unsatisfactory

bond between gypsum and portland cement materials.

***************************************************************************

Apply finish over gypsum-sand base coat only, scratch in thoroughly, lay on

well, double back, and fill out to a true, even surface. Allow the finish

to dry a few minutes, then trowel it well with water. Apply maximum

pressure in order to compact the finish coat and provide a smooth finish

free of blemishes and irregularities. Continue troweling until the finish

sets.

3.3.3.3 Gypsum Sand Float Finish Coat

***************************************************************************

NOTE: Specify type of float required to produce the

texture desired.

***************************************************************************

Apply finish over the base coat, scratch in thoroughly, lay on with a trowel

to an even surface, and then float with [_____] floats to a true, even

surface, free of slick spots or other blemishes. Apply sand float finishes

to a maximum thickness of 3 mm (1/8 inch) except as necessary to level out

hollow spots.

3.3.3.4 Acoustical Plaster Finish Coat

Apply finish in accordance with manufacturer's printed instructions and in

the thickness necessary to provide the sound absorption coefficient

specified, but not be less than 13 mm (1/2 inch) thick.

3.4 ORNAMENTAL PLASTER WORK

Complete ornamental work before the finish coat of plaster is applied to

adjoining areas. Plaster for ornamental work must consist of a mixture that

will produce satisfactory results for the respective conditions, be

reinforced properly with fiber or zinc-coated steel wire netting as

necessary to provide permanent construction, and be rigidly secured in

place. Run plain moldings in place to templates and guides, with true

radial lines for curved work; where it is not practicable to run such

moldings, cast or run them on a bench and then secure in place firmly.

Cornices and moldings must be straight or curved, true to line, and corners

neat.



3.5 PATCHING AND POINTING

Cut out and patch loose, cracked, damaged, or defective gypsum plaster.

Patch must match existing work in texture, color and finish flush with

previously applied gypsum plaster surfaces. Point work abutting or

adjoining finish work in a neat manner. Remove droppings or spatterings

from surfaces. Leave clean and in a condition to receive paint or other

finish. Remove protective covering from floors and other surfaces, and

rubbish and debris from [the interior and exterior of] the building.

1.2 GENERAL REQUIREMENTS

***************************************************************************

NOTE: Select either the one or two-coat system. The

one-coat is slightly lower in cost, requires less

installation time, and requires only one plastering

material on the job. The two-coat system has greater

crack resistance and is more resistant to damage.

The one-coat system should be used where appearance

is the sole consideration. The two-coat system

should be used where physical abuse is a

consideration.

***************************************************************************

Except where otherwise indicated or specified, conform to ASTM C754, ASTM

C843, and ASTM C844. Apply the gypsum veneer plaster as a [one coat] [two

coat] system over a special gypsum base. The veneer plaster, gypsum base,

and joint reinforcement must be products of the same manufacturer. The

extent and location of veneer plaster must be as shown on the drawings.

Metal framing is specified herein. [Wood framing specified in Section 06 10

../Word/01%2033%2029.doc

../Word/01%2033%2029.doc

../Word/01%2033%2000.doc



Deliver and store plaster materials in the manufacturer's original unopened

containers. Store materials off the ground within a completely enclosed

structure or enclosed within a weathertight covering. Store gypsum base and

gypsum backing board flat to prevent warping and protect from excessive

exposure to sunlight. Keep materials wrapped and separate from off-gassing

materials, such as paint and adhesives. Do not use materials that have

visible moisture or biological growth.

1.5 SCHEDULING

Commence application only after the area scheduled for veneer plaster work

is completely weathertight. The heating, ventilating, and air-conditioning

systems must be complete and in operation prior to application of the

plaster. If the mechanical system cannot be activated before veneer

plastering is begun, the plastering may proceed in accordance with an

approved plan to maintain the environmental conditions specified below.

Apply plaster prior to the installation of finish flooring and acoustic

ceiling.

1.6 ENVIRONMENTAL REQUIREMENTS

***************************************************************************

NOTE: Veneer plaster is a very thin coating that

will be adversely affected by extreme or non-uniform

drying conditions and by rapid changes in

temperature. It should not be used in spaces where

adequate environmental control cannot be obtained.

***************************************************************************

Do not expose the gypsum base to excessive sunlight prior to plaster

application, as bond failure of the plaster may result. Maintain a

continuous uniform temperature of not less than 10 degrees C (50 degrees F)

and not more than 27 degrees C (80 degrees F) for at least one week prior to

the application of veneer plaster, while the plastering is being done, and

for at least one week after the plaster is set. Shield air supply and

distribution devices to prevent any uneven flow of air across the plastered

surfaces. Provide ventilation to exhaust moist air to the outside during

plaster application, set, and until plaster is dry. In glazed areas, keep

windows open top and bottom or side to side 75 to 100 mm (3 to 4 inches).

Openings can be reduced in cold weather. For enclosed areas lacking natural

ventilation, provide temporary mechanical means for ventilation. In

unglazed areas subjected to hot, dry winds or temperature differentials from

day to night of 10 degrees C (20 degrees F) or more, screen openings with

cheesecloth or similar materials. Avoid rapid drying. During periods of

low indoor humidity, provide minimum air circulation following plastering

and until plaster is dry.

[1.7 FIRE RESISTIVE CONSTRUCTION

PART 3 EXECUTION

3.1 STEEL FRAMING

***************************************************************************

NOTE: Since the veneer plaster is a thin, hard

coating, it may be damaged by excessive deflection or

racking of the partition. Partitions should be

isolated from the structural building frame so that

movement of the frame does not distort the

partitions. Where heavy loads such as wall hung

cabinets, counters or hospital TV sets are indicated,

the partitions must be strengthened to support the

applied loads.

***************************************************************************

ASTM C754. Space framing at 400mm (16 inches) on center maximum.

Partitions must support applied loads such as cabinets and counters without

exceeding the permitted deflection.

3.1.1 Partition Framing System

Metal non-load bearing framing and furring system must be capable of

carrying a transverse load of 24 ksm (5 psf) without exceeding either the

allowable stress or a deflection of L/240. Provide studs of 0.45 mm (0.0179

inch) minimum thickness for partitions having the same material and the same

material thickness on both sides. For partitions using 0.45 mm (0.0l79

inch) thick studs, the surfacing material must cover the full height of the

partition on both sides, or the stud flange must be otherwise supported to

insure rigidity. Provide studs of 0.84 mm (0.0329 inch) minimum thickness

for partitions having different materials or different material thickness on

the two sides. At partition ends, corners, and intersections, and at jambs

of openings, fasten studs to runners with screws.

3.1.2 Special Framing

Build framing for beams, columns, soffits, and other special items to the

sizes, shapes, or forms indicated. Secure rigidly at each intersection with

screws.

3.1.3 Shaftwall Framing System

Shaftwalls must be standard, tested designs. Metal framing must be in

accordance with the shaftwall manufacturer's printed instructions.

3.1.4 Ceiling Openings

Provide support members at ceiling openings such as required for access

panels, recessed light fixtures, and for air supply or exhaust. Locate



support members of not less than 38 mm (1 1/2 inch) main runner channels and

suspension wires or straps to provide at least the minimum support specified

herein for furring and wallboard attachment. Provide intermediate

structural members for attachment or suspension of support members.

3.1.5 Wall Openings

At wall openings the framing system must provide for the installation and

anchorage of the required subframes or finish frames. Attach steel frames

securely through built-in anchors to the nearest stud on each side of the

opening with wallboard screws. Provide 0.84 mm (0.329 inch) minimum

thickness double studs at both jambs of all doors openings. For doors over

1200 mm (4 feet) wide, double doors, and for extra-heavy doors (such as x-

ray doors), provide doubled studs [_____] millimeters (inches) minimum

thickness. Spot grout door frames at the jamb anchor locations with joint

compound applied just prior to application of gypsum base.

3.1.6 Blocking

Provide blocking when mounting equipment. Cut[ metal][ or][ wood] blocking

to fit in between the framing members. Rigidly anchor blocking to the

framing members. Under no circumstances will accessories or other wall

mounted equipment be anchored directly to the veneer plaster system.

3.2 APPLICATION OF GYPSUM BASE

Apply gypsum base and gypsum backing board to framing and furring members in

accordance with ASTM C844 and the requirements specified herein. Gypsum

wallboard may be used for the base ply in two-ply construction. Provide

gypsum base and backing board of maximum practical length, using full length

boards for vertical application. Install separate boards in moderate

contact without forcing in place. Install boards tight against the framing

so as to eliminate any offset in the face plane between adjoining boards.

Stagger end joints of adjoining boards. Fit abutting end and edge joints.

Cut boards as required to make close joints around openings. Gypsum base

may be adhered to gypsum backing board with an adhesive, except where

prohibited by fire rating. In multi-layer construction, offset joints

between layers. Offset joints on opposite faces of the partition.

3.2.1 Curved Surfaces

Use bending radii in accordance with ASTM C844, TABLE 5. Bend gypsum base

into place without damaging the face paper. If the base is dampened to

facilitate bending, dry thoroughly, and apply a bonding agent (ASTM C631)

before plastering.

3.2.2 Cavity Shaftwall System

Install gypsum backing boards, core boards, and gypsum base in accordance

with the shaftwall system manufacturer's printed recommendations to achieve

the fire rating required.

3.2.3 Control Joints

***************************************************************************

NOTE: Control joint locations should be shown on the

drawings. Control joint spacing in walls or wall



furring must not exceed 9000 mm (30 feet). Control

joint spacing must not exceed 9000 mm (30 feet) in

either direction in restrained ceilings, and 15000 mm

(50 feet) in either direction in ceilings with

perimeter relief. Joints should be provided at the

wings of L, U, and T shaped ceiling areas.

***************************************************************************

Control joints in ceilings and walls must be one piece manufactured products

designed for use with a veneer plaster system.

3.2.4 Vapor Retarder

Install foil-backed gypsum base or gypsum backing board with the reflective

surface against the framing members. Install polyethylene vapor retarder

with joints over framing members, and with joints lapped the full width of

the framing members.

3.3 JOINT REINFORCEMENT

Reinforce all interior angles and flat joints prior to application of the

veneer plaster. Do not use self-adhering fiberglass mesh tape.

Reinforcement must be a special mesh reinforcing strip embedded in veneer

plaster, or paper gypsum wallboard tape embedded in joint compound.

3.3.1 Mesh Reinforcing

Embed the mesh reinforcing strip in veneer plaster, so that embedment

material is both under and covering the reinforcement. Allow areas of

reinforcement to preset, and leave rough enough for proper bonding of the

plaster coat. Reinforcement must be set but not dry, before the application

of veneer plaster.

3.3.2 Paper Tape Reinforcing

Press the paper tape into a bedding coat of setting type joint compound, and

immediately cover with a skim coat of the same compound. After the bedding

and skim coats are set, apply a fill coat of joint compound. Set the

reinforcement and dry thoroughly before application of veneer plaster.

3.4 APPLICATION OF GYPSUM VENEER PLASTER

***************************************************************************

NOTE: Veneer plaster may be applied to masonry or

concrete surfaces as well as to gypsum base. Special

conditioning and treatment are required for masonry

or concrete surfaces to receive veneer plaster.

Review ASTM C843 and manufacturer's literature to

determine requirements applicable to the project, and

modify this section accordingly. Note that any

cracking of the substrate will result in cracking of

the plaster.

***************************************************************************

Apply gypsum veneer plaster in accordance with ASTM C843, and with the

manufacturer's approved installation instructions where such instructions

are additional to or more restrictive than the requirements of ASTM C843.



Apply plaster as a [one-component] [two-component] system. Minimum plaster

thickness must be as recommended by the manufacturer, but must in no case be

less than[1.6 mm(1/16 inch) for one-component system.] [1.6 mm(1/16 inch)

for base coat and 0.8 mm (1/32 inch) for finish coat of a two-component

system.]

3.4.1 Mixing

Clean mixer between batches to avoid accelerating the setting time. Do not

add other plaster materials to modify the properties of the veneer plaster.

When extreme conditions so demand, small quantities of commercial retarder

or accelerator may be added to the mixing water to adjust setting time.

When used, the retarder or accelerator must conform to the veneer plaster

manufacturer's recommendations.

3.4.2 Application

Trowel plaster on by hand. Apply with sufficient material and pressure to

develop bond and to provide the specified component thickness.

3.4.2.1 Base Coat

***************************************************************************

NOTE: Delete base coat requirements when one-

component system is desired.

***************************************************************************

Scratch in the base coat tightly, then immediately double back using

material from the same batch. Fill all voids and imperfections and level

the plaster to a true surface without the application of water. For good

bond or adhesion, roughen the final surface for bond by brushing or cross-

raking with a fine wire rake. For application of finish coat, set the base

coat and partially dry. If the base coat is totally dry, dampen before

finish coat application.

3.4.2.2 Finish Coat

***************************************************************************

NOTE: A smooth-troweled finish will normally be

specified. If a textured finish is desired, it may

be added to the specification. The texture pattern

should be specified, i.e., swirl, skip trowel, etc.

Some texture finishes may require a greater coating

thickness.

***************************************************************************

Scratch in the finish coat tightly, then immediately double back using

material from the same batch. After the plaster has been allowed to set up

slightly, lightly trowel the surface without the addition of water, filling

all voids and imperfections and eliminating surface irregularities. When

the plaster has become firm and prior to set, smooth-trowel the surface

using water sparingly. Avoid over troweling.

3.5 CLEANUP AND PATCHING



Remove plaster splashes from adjacent surfaces. Repair defects in the

veneer plaster. Plaster surfaces must be smooth, clean, and in condition to

receive the finishing materials that will be applied.

1.4 DELIVERY, STORAGE, AND HANDLING

1.4.1 Delivery

Deliver materials in the original packages, containers, or bundles with each

bearing the brand name, applicable standard designation, and name of

manufacturer, or supplier.

1.4.2 Storage

***************************************************************************

NOTE: Gypsum board provides a sink for adsorbing

high short-term emissions of VOCs, formaldehyde,

particulates, or other air-borne compounds.

Materials with high short-term emissions include, but

are not limited to: adhesives, sealants and glazing

compounds (specifically those with petrochemical

vehicles or carriers); paint, wood preservatives, and

finishes; control and/or expansion joint fillers;

hard finishes requiring adhesive installation; gypsum

board (with associated finish processes and

products); and composite or engineered wood products

with formaldehyde binders.

***************************************************************************

Keep materials dry by storing inside a sheltered building. Where necessary

to store gypsum board and cementitious backer units outside, store off the

ground, properly supported on a level platform, and protected from direct

exposure to rain, snow, sunlight, and other extreme weather conditions.

Provide adequate ventilation to prevent condensation. Store per

manufacturer's recommendations for allowable temperature and humidity range.

Do not store gypsum wallboard with materials which have high emissions of

volatile organic compounds (VOCs) or other contaminants, including [_____].

Do not store panels near materials that may offgas or emit harmful fumes,

such as kerosene heaters, fresh paint, or adhesives. Do not use materials

that have visible moisture or biological growth.

1.4.3 Handling

sagging or damage to the edges, ends, and surfaces.

1.5 QUALIFICATIONS

Furnish type of gypsum board work specialized by the installer with a

minimum of [3] [_____] years of documented successful experience.

1.6 SCHEDULING

***************************************************************************

NOTE: Use one or both of the following procedures to

minimize the exposure of gypsum wallboard to

materials or finishes which have high short-term

emissions of VOCs, formaldehyde, particulates, or

other air-borne compounds.

***************************************************************************



[The gypsum wallboard must be taped, finished and primed before the

installation of the highly-emitting materials, including [_____].] [The

gypsum wallboard must be installed after the installation and ventilation

period of the highly-emitting materials, including [_____].]

Commence application only after the area scheduled for gypsum board work is

completely weathertight. The heating, ventilating, and air-conditioning

systems must be complete and in operation prior to application of the gypsum

board. If the mechanical system cannot be activated before gypsum board is

begun, the gypsum board work may proceed in accordance with an approved plan

to maintain the environmental conditions specified below. Apply gypsum

board prior to the installation of finish flooring and acoustic ceiling.


***************************************************************************

NOTE: Gypsum board is a thin sheathing that will be

adversely affected by extreme or non-uniform drying

conditions and by rapid changes in temperature. It

should not be used in spaces where adequate

environmental control cannot be obtained.

***************************************************************************

Do not expose the gypsum board to excessive sunlight prior to gypsum board

application. Maintain a continuous uniform temperature of not less than 10

degrees C (50 degrees F) and not more than 27 degrees C (80 degrees F) for

at least one week prior to the application of gypsum board work, while the

gypsum board application is being done, and for at least one week after the

gypsum board is set. Shield air supply and distribution devices to prevent

any uneven flow of air across the plastered surfaces. Provide ventilation

to exhaust moist air to the outside during gypsum board application, set,

and until gypsum board jointing is dry. In glazed areas, keep windows open

top and bottom or side to side 75 to 100 mm (3 to 4 inches). Reduce

openings in cold weather to prevent freezing of joint compound when applied.

For enclosed areas lacking natural ventilation, provide temporary mechanical

means for ventilation. In unglazed areas subjected to hot, dry winds or

temperature differentials from day to night of 10 degrees C (20 degrees F)

or more, screen openings with cheesecloth or similar materials. Avoid rapid

drying. During periods of low indoor humidity, provide minimum air

circulation following gypsum boarding and until gypsum board jointing

complete and is dry.

PART 3 EXECUTION

3.1 PREPARATION

Do not start tile work until rough-in for plumbing, heating, ventilating,

air conditioning, and electrical work has been completed and tested [and

membrane waterproofing has been installed and tested]. Protect the work of

other trades in area where tile work is to be done.

3.1.1 Preparation of Tile

***************************************************************************

NOTE: According to manufacturers, the prefinished

wax surface is no longer available. Factory-coated

units should be specified, if available, when

experience indicates that application of wax in the



field is unsatisfactory. Used as a protector for

epoxy or furan grout - verify with the tile

manufacturer if this is avaialble. Once grouting is

complete, wax should be steamed off and removed.

When factory coated units are not selected, add

language to require the application of a sealer and

grout release agent per manufacturer's

recommendations.

***************************************************************************

[Factory coat] [Coat] with hot paraffin wax to produce a thin continuous

film on the face surfaces only of quarry tile units to be installed and

grouted with furan. Apply wax in such manner that it will not get on edges

or backs of tile. Handle tile in a manner that will prevent waxed surfaces

of units from touching the backs or edges of other units. Remove from the

job tile with wax on edges or backs. Verify that wax used is acceptable to

grout manufacturer. With flatback or serrated back tile use 6 mm (1/4 inch)

square notched trowel with notches on 13 mm (1/2 inch) centers.

3.1.2 Preparation of Concrete Floors for Setting Beds

***************************************************************************

NOTE: Where tile is to be installed, concrete slabs

should not have air entrainment or other additives in

the mix, nor sealers or curing compounds applied

without specific approval of mortar and grout

manufacturer. Slabs should have steel trowel and

fine broom finish and be free of laitance. In case

of any question on condition of slab, it should be

tested for bondability with a Dillon Dynamometer and

show a tensile bond of not less than 2068 kPa (300

psi). These requirements should be incorporated in

Section 03 30 00.00 10 CAST-IN-PLACE CONCRETE

***************************************************************************

Before tile is applied, test structural floor for levelness or uniformity of

slope by water. Fill, level, and retest areas as required to meet

tolerances specified in TCNA Hdbk and retest. When specified levelness or

uniformity of slope is obtained, prepare floors for setting bed in

accordance with TCNA Hdbk. Free floors of sealers, coatings, oil, dirt, and

dust. Prepare floors before application of resin mortar in accordance with

printed instructions and recommendations of the mortar manufacturer.

3.2 INSTALLATION

Except where specified otherwise herein, apply materials in accordance with

manufacturer's printed instructions, including recommended safety

requirements.

3.2.1 Setting Bed

Using a plain (not serrated) trowel, apply a continuous setting bed of

chemical-resistant mortar, not less than 3 mm (1/8 inch) thick. Apply only

over a floor area that can be tiled during "open time" of mortar. Place

tile into setting bed and tap lightly to a true plane. Level tile as it is

placed. Maintain uniform tile joints of 6 mm (1/4 inch) minimum and 10 mm

../Word/03%2030%2000.00%2010.doc



(3/8 inch) maximum width. Allow the setting bed to cure sufficiently to

anchor tile in place, but not less than 24 hours, at a floor temperature of

not less than 16 degrees C (60 degrees F). When furan setting bed is used,

first install a glass reinforced asphalt membrane. With flatback or

serrated back tile use trowel with 6 mm (1/4 inch) square notches on 13 mm

(1/2 inch) centers.

3.2.2 Tile Joints

After the setting bed has cured, fill tile joints with chemical-resistant

grout. Spread grout on surface of tile and work it into the open joints

with a trowel. Fill joints flush with top surfaces of tile. Remove excess

grout with one pass of a trowel or squeegee pulled diagonally across joints

in order to prevent imperfect filling and low joints. Immediately fill

voids, pinholes, and depressions with additional grout. Protect completed

joints from dampness. Permit grout to harden for not less than 72 hours.

Flush cure joints with tile edges; contour depression must not exceed 1.2 mm

for 6 mm (3/64 inch for 1/4 inch) wide joints or 2 mm for 10 mm (1/16 inch

for 3/8 inch) wide joints. Sealants for expansion joints provided by the

grout manufacturer must be compatible with grout and setting mortars.

Completely fill joints with no back up foam or rope. Install joints maximum

6000 mm (20 feet) on center above slab around room peripheries and columns

but not at drains.

3.2.3 Tile Installation

Install and grout tile with water cleanable tile setting and grouting epoxy

in accordance with TCNA Hdbk.

3.3 CLEANING

After grout has hardened, scrub and wash tile surfaces with steam or hot

water to melt wax coating and remove excess grout. Remove remnants of grout

with wide-bladed paint scraper or other tool that will not damage tile.

Rinse tile with clean warm water applied with a flat sponge. Remove excess

water from floor, and leave floor dry when work is completed. Remove tile

from which surface grout cannot be removed without damage to tile. Remove

damaged tile and provide new tile.

3.4 PROTECTION

Cover finished tile floors with clean building paper before permitting foot

traffic on them. Place board walkways on floors that are to be continuously

used as passageways by workmen.

requirements for wood strip and plank flooring for

gymnasiums, handball and squash courts, and other

special purpose applications.











present.




***************************************************************************

PART 1 GENERAL

1.1 SUMMARY

***************************************************************************

NOTE: Wood strip flooring is very sensitive to

ambient humidity conditions since all wood flooring

will expand and contract as relative humidity varies.

In order to keep the flooring manufacturer's warranty

valid after installation, the areas in which the wood

floors are installed must be adequately ventilated

with natural or mechanical air circulation at all

times during the life of the flooring.





If prior experience at the site indicates that

relative humidity during sustained heating periods

will fall below 35 percent, the office in charge of

building maintenance should provide equipment to

introduce moisture into the floored area when

required; conversely, if relative humidity increases

to 50 percent or higher at any time, measures should

be taken to dry the floored area, including turning

on the heat.

At sites with humidity problems, the maintenance of

the flooring may require: 1) The design of a

localized HVAC system to also react to and

automatically control ambient humidity conditions

through the life of the flooring; or 2) Continuous

monitoring of relative humidity with on the spot

corrective actions, as needed, without altering the

HVAC system. These alternatives could be very

expensive or impractical. The designer, in the

absence of local experience, should coordinate with

local manufacturers to specify compatible floorings

which have performed well locally; that is, the

designer should check gymnasiums in the area when

building a gymnasium floor; the same for handball

courts, etc. Of course, the designer has the option

of purchasing commercially available floating or

sleeper systems specifically designed to reduce the

possibility of buckling and cupping brought on by

moisture buildup or specifying other types of

flooring when a cost analysis (including all HVAC

variations) indicates that wood strip flooring is not

economical.

***************************************************************************

This specification is written to allow the Contractor to build wood strip

floorings for gymnasiums, handball and squash courts, and other special

purpose applications but does not preclude the installation of competitive,

manufacturer standard, integrated systems.

PART 3 EXECUTION

3.1 TERRAZZO PROPORTIONS

3.1.1 Underbed

Use underbed composed of one part portland cement to [4] [4.5] parts sand.

Add water to provide workability at as low a slump as possible. Spread to a

level 13 mm (1/2 inch) below the finished floor, to a thickness of

approximately 30 mm (1-1/4 inches).

3.1.2 Terrazzo Topping

Topping must be composed of one 43 kg (94 pound) bag of portland cement per

91 kg (200 pounds) of marble chips and approximately 20 L (5 gallons) of

water. Add color pigment as needed, but not to exceed 1 kg (2 pounds) per

bag of cement. Add water in sufficient quantity to provide workability at

as low a slump as possible.

3.2 INSTALLATION

Submit drawings indicating the type, size, and layout of divider strips and

control joint strips and color of floor areas.

3.2.1 Underbed Placement



Clean and saturate concrete surfaces with water in accordance with NTMA Info

Guide. Do not treat concrete substrate to receive bonded terrazzo with

curing agent or additives which would preclude bonding. Remove excess water

from the subfloor before slushing and brooming with neat cement paste.

Place the underbed on the concrete subfloor and screed to an elevation 13 mm

(1/2 inch) below the finished floor. Install divider strips in the

semiplastic underbed. Firmly trowel the underbed along the edges to insure

positive anchorage of the divider strips. Install control joint strips over

subfloor expansion joints and extend the full depth of the underbed.

3.2.2 Setting Divider Strips

Set in accordance with layout indicated while underbed is still plastic.

Set strips to straight lines and to the proper level to ensure that tops of

strips will show uniformly after completing grinding and finishing

operations. Fit joints and intersections tight. Where divisions in field

work are not shown, divide field work into squares or rectangles of uniform

size and not more than 1800 mm (6 feet) on a side. Divide borders by strips

to coincide with the layout of division strips in the field of floors.

Place edging strips at doorways between terrazzo and other types of flooring

and along the edges of terrazzo borders adjoining other types of floor

finishes or floor coverings. Place expansion strips over control joints,

construction joints, and expansion joints.

3.2.3 Placing Terrazzo Topping

Slush and broom the underbed in accordance with NTMA Info Guide with neat

cement paste of the same color as required for the topping. Place the

topping in panels formed by divider strips and trowel level with the top of

the strips. Seed the troweled surface with chips in the same color

proportions as contained in the terrazzo mix, trowel and roll with heavy

rollers until excess water has been extracted. Trowel the terrazzo to a

uniform surface disclosing the lines of the divider strips.

3.2.4 Curing

Cure the terrazzo until the topping develops sufficient strength to prevent

lifting or pulling of terrazzo chips during grinding. Keep the completed

terrazzo continuously moist and free of traffic during the curing period.

Cure by covering with a liquid membrane-forming compound, sheet materials,

wet sand, or sprinkling with water.

3.2.5 Finishing

[Finish in accordance with NTMA Info Guide.] [After curing the grout coat

for a minimum of 72 hours, grind the floor using a No. 80 or finer grit

stone. In the latter stages of grinding, use grit stones or other abrasive

in the grinding machine of a grain or fineness that will give the surface a

honed finish. Grind and rub by hand small areas, inaccessible portions, and

corners that cannot be reached by the grinding machine. The honed surface

of finished terrazzo must show not less than 70 percent of the area as

exposed aggregate evenly distributed, and conform in appearance to the

approved samples. Finished thickness of terrazzo topping must be a minimum

of 13 mm (1/2 inch).]

3.2.5.1 Rough Grinding



After topping has cured, machine gring the terrazzo using the wet method, to

a true even surface using No. 24 or finer grit followed by No. 80 grit or

finer grit stone. Finish floor surface must not vary by more than 2

mm/meter (1/4 inch in 10 feet).

3.2.5.2 Grouting

After rough grinding, cleanse and rinse the floor with clean water. After

removing excess rinse water, grout the floor using identical portland

cement, color and pigments as used in the topping taking care to fill voids.

After the grout has attained its initial set, cure the surface for a minimum

of 72 hours.

3.2.5.3 Fine Grinding

After grout has cured, gring the surface with fine grit stones until all

grout is removed from the surface. Upon completion of grinding, the

terrazzo flooring must show a minimum of 70 percent of marble chips. Submit

two 150 x 150 mm (6 x 6 inch) (minimum) samples of each color of terrazzo

3.3 CLEANING AND SEALING

Wash the terrazzo with a neutral cleaner and, where required, clean with a

fine abrasive to remove stains or cement smears. Rinse the cleaned surface.

When dry, apply a terrazzo sealer in accordance with the manufacturer's

directions.

3.4 PROTECTION

cover and protect the terrazzo work from damage until completion of the work

of all other trades.

***************************************************************************


requirements for resinous terrazzo flooring and

conductive resinous terrazzo flooring.











present.




***************************************************************************

PART 1 GENERAL

***************************************************************************

NOTE: The resinous terrazzo floor systems covered by

this guide specification may be used in lieu of

portland cement terrazzo where the light weight of

the thin set system would be advantageous.

The conductive resinous terrazzo flooring is

primarily intended for use in areas where volatile

materials are handled, clean-rooms, parachute

assembly areas, etc. These systems, which have a

wear factor four times better than cementitious

terrazzo and five to six times better than vinyl may

be used, when economically justified, in hard wear

areas where there is a need for a high degree of

cleanliness, a decorative effect, and some chemical

resistance. These systems will not be used over





lightweight concrete and will not be used in lieu of

quarry tile in kitchens.

The selection of a floor system for a location where

resistance to specific conditions is important should

be based upon the ability of the system to withstand

required exposure conditions. For example,

polyesters are suitable where resistance to

detergents is required but should not be used in

laboratory or other areas where spillage of sodium

hydroxide or similar strong alkaline solution occurs;

epoxies should not be used where resistance to

oxidizing acids is required or where resistance to

temperatures in excess of 54 degrees C (130 degrees

F) is required; latex mastic and resin emulsions

should not be used where resistance to strong acids

or alkalis is required. Each job should be evaluated

on its own merits considering exposure conditions,

costs, and local experience with the various systems.

Areas to receive terrazzo will be shown on the

drawings. Color should be shown by specifying a

selected plate number from the NTMA publication,

"Terrazzo Information Guide." Example: NTMA

terrazzo catalog, plate No. S-301-4. Colors selected

may be any combination of standard marble granules of

domestic origin available in the local market, but it

is highly desirable that color combinations be

designated by NTMA color plates.

***************************************************************************

1.1 SUMMARY

***************************************************************************

NOTE: Conductive floors will be used at operations

where explosives having an electrostatic sensitivity

of 0.1 joule or less such as primer, detonator,

igniter, and incendiary mixtures are exposed.

Conductive floors are also required where the

following are performed:

a. Loose unpacked ammo with electric primers.

b. Exposed electro-explosive devices.

c. Electrically initiated items with exposed

electric circuitry.

d. Hazardous materials that could be ignited by

static discharge from humans.

***************************************************************************

Apply resinous terrazzo flooring, in the colors indicated, in the areas

shown on the detail drawings. Submit two 150 x 150 mm (6 x 6 inches),

(minimum) samples of each color of resinous terrazzo and two 150 mm (6

inches) lengths, of each type of strip. Flooring must be [[an epoxy

terrazzo system that conforms to the requirements specified in paragraphs

2.01A and B of NTMA Info Guide][ or ][a polyester terrazzo flooring system

that conforms to the requirements specified in paragraphs 2.01A and B of

NTMA Info Guide.]] [a conductive [epoxy terrazzo system that conforms to the

PART 3 EXECUTION

3.1 PREPARATION OF CONCRETE SUBFLOOR

Do not commence installation of the floor topping until the concrete

substrate has cured for at least 28 calendar days. Prepare the concrete

surfaces in accordance with the instructions of the resin manufacturer.

3.2 MIXING, PROPORTIONING, AND INSTALLATION

***************************************************************************

NOTE: Terrazzo topping thickness will be determined

by the marble chip size indicated in the selected

NTMA-01 color plate referenced in paragraph MARBLE

CHIPS. If the cross-section is less than 10 mm (3/8

inch) the use of No. 1 and No. 0 size chips will be

required. Delete last sentence if resinous terrazzo

bases are not required.

***************************************************************************

Mixing, proportioning, and installing must be in accordance with the

approved instructions of the manufacturer. Install strips in locations

indicated. Appply the topping to give a finish thickness of [6] [10] mm

([1/4] [3/8] inch). Provide cove type bases cast-in-place with 25 mm (1

inch) radius cove and [100] [150] mm ([4] [6] inch) high.

3.3 TESTING

Between 30 and 45 days after flooring installation is completed, and prior

to its use, test the conductive resinous terrazzo flooring in accordance

with paragraph 12-4.1.3.8(b)(7) of NFPA 99. The resistance of the

conductive floor at any one location must be more than 5,000 ohms in areas

with 110 volts service, more than 10,000 ohms in areas with 220 volt

service, and average less than 1,000,000 ohms and more than 25,000 ohms in

all areas. Submit certificates indicating conformance with specified

requirements. Accompany certificates with certified test reports showing

that the conductive resinous terrazzo floor has been tested and meets the

requirements specified.

3.4 CLEANING AND SEALING

***************************************************************************

PART 1 GENERAL

***************************************************************************

NOTE: The floor systems covered by this guide

specification are primarily intended for use in

biological laboratories, in similar areas which are

subject to hard wear or spillage of chemicals and

require a high degree of cleanliness, and for

explosive and ammunition facilities.

These systems are for use over normal weight concrete

and will not be used over lightweight concrete. The

selection of a floor system for a location where

resistance to specific chemical conditions is

important should be based upon the ability of the

system to withstand required exposure conditions.





For example, polyesters are suitable for use where

resistance to detergents is required but should not

be used in laboratory or other areas where spillage

of sodium hydroxide or similar strong alkaline

solution occurs; epoxies should not be used where

resistance to oxidizing acids is required or where

resistance to temperatures in excess of 54 degrees C

(130 degrees F) is required. Each job should be

evaluated on its own merits considering exposure

conditions, costs, flammability of materials, and

local experience with the various systems. All

provisions relating to the systems not selected will

be deleted.

Check other sections of the specifications to ensure:

1. No vermiculite or perlite aggregates in concrete

substrates.

2. No curing compounds or sealers on concrete

substrates.

3. New concrete receives single trowelled finish;

and no burnished finishes.

4. Vapor barrier is provided under all concrete

slabs-on-grade.

5. Only exterior grade plywood on new plywood

substrates. No interior grade or interior grade with

exterior glue. Plywood is nailed with annular ring

or spiral nails only.

6. No dimension lumber substrate in new

construction; when existing lumber substrates are to

be covered, overlay with 50 by 50 mm (2 by 2 inch)

mesh hardware cloth.

On the drawings, show:

1. Location of resinous flooring. If more than one

type is to be used, key each to location on the

drawings.

2. Details of special items such as coved bases,

expansion joints, control joints, stairs, and floor

drains.

3. Details for grounding of conductive floors.

2.12 CARPET

***************************************************************************

NOTE: If more than one carpet type is required for a

project, use a separate paragraph for each carpet

type. Designate each carpet type with a letter or

number symbol. Use the same designations to key

carpets to locations on the drawings and in Section

09 06 00 SCHEDULES FOR FINISHES.

ADA Requirements: Carpet must be securely attached;

have a firm cushion, or backing, or no cushion; and

have a level loop, textured loop, level cut pile, or

level cut/uncut pile texture. The maximum thickness

should be 13 mm (1/2 inch). Fasten exposed edges of

carpet to floor surfaces and have trim along the

entire length of the exposed edge.

Nylon fiber is typically abrasion resistant and

durable in all pile configurations using filament

fiber, has good stain removal characteristics, and is

recommended for commercial installations.

Triexta (PTT) fiber is recommended for both

commercial and residential installations. For

commercial installations, triexta offers excellent

durability, resiliency and crush resistance that is

suited for high-traffic areas. Permanent stain

resistance, bleach resistance and colorfastness built

right into the fiber, make triexta carpets easy to

clean and will extend the life of a commercial

carpet. Residential installations will benefit from

these attributes as well as softness and comfort

under foot. Additionally, some triexta fibers

contribute to the biobased material requirement.

Polyethylene terephthalate (PET) recycled polyester

fiber has permanent fade resistance, is permanently

colorfast, has a permanent stain resistance which is

higher than other type fibers, is impervious to harsh

chemicals, and has the lowest static buildup. PET

type polyester carpet, once crushed under continued

high pressure, is less likely than nylon carpet to

rebound. PET carpet is not recommended for severe

and moderate wear level areas and should be limited

to light wear areas.

../Word/01%2033%2029.doc

../Word/01%2033%2029.doc

../Word/09%2006%2000.doc



Wool is a natural fiber, which is inherently flame

resistant, forming a char that will neither melt nor

drip. Wool is also rapidly renewable and resilient,

and due to the scaly character of its fiber it

scatters optical light, thus reducing soiling

visibility. Wool is highly recommended for shipboard

use due to it being inherently flame resistant.

Wool, cotton, jute, hemp and sisal carpets may not

meet accepted performance requirements of commercial

carpet. Verify suitability, availability and

adequate competition before specifying these

products.

Flexible and modular components, like carpet tile,

reduce the labor and materials costs related to

operations and maintenance, churn, and future

renovations.

Continuous dye process uses two to three times less

water than batch dyeing during manufacture.

***************************************************************************

Furnish first quality carpet; free of visual blemishes, streaks, poorly dyed

areas, fuzzing of pile yarn, spots or stains, and other physical and

manufacturing defects. Provide carpet materials and treatments as

reasonably nonallergenic and free of other recognized health hazards.

Provide a static control construction on all grade carpets which gives

adequate durability and performance. Submit manufacturer's catalog data and

printed documentation stating physical characteristics, durability,

resistance to fading, and flame resistance characteristics for each type of

carpet material and installation accessory. Submit manufacturer's catalog

data for 1) Carpet, 2) Carpet Cushion, and 3) Moldings. Also, submit

samples of the following:

when the project is designed by an Architect or

Interior designer. Select color from manufacturers

standard colors or identified as a manufacturers

color in this specification only when the project is

very simple and has minimal finishes.

When the Government directs that color be located in

the drawings add a note that states: "Where color is

shown as being specific to one manufacturer, an

equivalent color by another manufacturer may be

submitted for approval. Manufacturers and materials

specified are not intended to limit the selection of

equal colors from other manufacturers. The word

"color" as used herein includes surface color and

pattern."

Prior to specifying a custom color finish, research

to determine if additional cost and lead time is

feasible. Note there is often a minimum order

requirement; this requirement will also affect future

orders.

When a manufacturer's name, stock number, pattern,

and color is used, be certain that the product

conforms to this specification, as edited.
