. Locate the mock-up installation at [the local dealership][approved off-site location][_____]. Do not order
furniture systems for the project until the mock-up has been approved. Review of the mock-up may result in adjustments
to the product, layout and finishes. The approved mock-up can be used in installation.
1.2.4 ALTERNATE DESIGN
NOTE: Minor differences exist among different manufacturer's product. This
paragraph pertaining to an "alternate design" was written in order not to exclude
a manufacturer when an equally acceptable solution is proposed.
Manufacturers who are unable to provide workstations that conform exactly to the furniture layouts and typical
workstation types shown in the contract drawings, may submit alternate designs for consideration by the Contracting
Officer. Alternate designs shall meet or exceed the following criteria. Alternate designs that are submitted
but do not meet these criteria will be rejected. The alternate design shall provide workstations and components
of the same basic size and configuration shown, with only the sizes of the individual components within the workstation
changed to meet the standard product of the manufacturer or site conditions.
1.2.4.1 Component Requirements
The types of components or elements utilized shall be as shown on the drawings and as specified in PART 2 PRODUCTS
of this specification. The storage capacity, number of workstations accommodated, width of aisles, or workstation
configuration shall not be reduced.
1.2.4.2 Wiring Configuration
Alternate configurations shall support the circuiting and connection capabilities identified under the provisions
pertaining to power distribution of paragraph POWER AND COMMUNICATIONS. Generally any alternate will be acceptable
which involves only a variation in size or quantity that exceeds the specified configuration.
1.2.5 Sustainable Design
1.2.5.1 Local/Regional Materials
NOTE: Using local materials can help minimize transportation impacts, including
fossil fuel consumption, air pollution, and labor. Using materials harvested
and manufactured within a 500 mile radius from the project site contributes
to the following LEED credit: MR5. Coordinate with Section 01 33 29 LEED(tm)
DOCUMENTATION. Use second option if Contractor is choosing local materials
in accordance with Section 01 33 29 LEED(tm) DOCUMENTATION. Use second option
for USACE projects. Army projects will include option only if pursuing this
LEED credit.
[Use materials or products extracted, harvested, or recovered, as well as manufactured, within a [800][_____]
km[500][_____] mile radius from the project site, if available from a minimum of three sources.] [See Section
01 33 29 LEED(tm) DOCUMENTATION for cumulative total local material requirements. Furniture and materials may
be locally available.]
1.2.5.2 Environmental Data
[Submit Table 1 of ASTM E 2129 for the following products: [_____].]
1.2.5.3 Certification
Product shall be third party certified by GEI Greenguard Indoor Air Quality Certified, SCS Scientific Certification
Systems Indoor Advantage or equal. Certification shall be performed annually and shall be current.
1.2.6 Performance Requirements
Panels, spine walls, frames and frame covers, connection system, work surfaces, pedestals, shelf units, overhead
door cabinets, lateral files, locks, accessories, and miscellaneous hardware shall meet testing as specified.
ISO 9001 certified manufacturers may perform inhouse testing. Manufacturers not ISO 9001 qualified will be required
to produce testing by an independent testing laboratory. Component specific requirements are listed in appropriate
paragraphs.
1.2.6.1 Selected Components
Workstations shall conform to the requirements of BIFMA X5.5 and BIFMA X5.6 with the following exceptions: Panels,
spine walls and panel, or spine wall supported components shall be tested and pass in accordance with the requirements
of BIFMA X5.6 and representative items shall be selected for testing based on worst case situations (i.e., the
deepest and widest work surface or shelf). Perform the keyboard drawer or shelf test applying a 19 kg 50 lb
load to the center of the keyboard shelf for a period of 5 minutes. Any loosening of attachments, permanent
deflection or damage to the operation of the drawer or shelf will be cause for rejection.
1.2.6.2 Panel Acoustics
NOTE: Consider using non-acoustical panels when storage units cover more than
half of the panel surface as the acoustical advantage is lost and the stronger
non-acoustical unit is less expensive.
Acoustical performance ratings should be based upon the workstation design.
While NRC and STC ratings contribute to overall acoustical performance, the
acoustical role of panels is relatively minimal in the overall environment when
compared to sound absorptive properties of other finish surfaces. Most major
manufacturers do not comply with the higher 0.80 NRC and 24 STC without providing
their more costly high performance panels. The designer must determine if the
additional acoustical performance is worth the added cost to the Government.
Designer must coordinate NRC and STC requirements for panel heights above 1200
mm (48 inches).
Delete paragraph if acoustical panels are not required.
Provide acoustical panels with a minimum noise reduction coefficient (NRC) of [0.65] [0.80] [_____] when tested
in accordance with ASTM C 423 and a minimum sound transfer coefficient (STC) of [14] [20] [24] [26] [_____] when
tested in accordance with ASTM E 290. Conduct the test on the entire assembled panel, full face area (the complete
core, adhesive, decorative fabric, frame and joining components).
1.2.6.3 Panel Glazing
NOTE: Curved glazed panels should not be specified since most products utilize
an acrylic glazing. Acrylic glazing is not acceptable since it does not meet
flame spread and smoke development requirements.
Tempered glass shall conform to ASTM C 1048, Kind FT, Condition A, Type I, [Class 1 Transparent] [Class 3 - Light
reducing, tinted or translucent].
1.2.7 Pattern and Color
NOTE: Include a reference to Section 09 06 90 COLOR SCHEDULE or drawings for
all items requiring a finish color. This includes the following items when
applicable: Work surfaces, Storage Units, Tackboards, Erasable Marker Boards,
Signage, Slat Tile, Panels, Stacking Panel Frames, Spine walls, Screens, Connectors,
Trim and Accessories. Specify both sides of panels.
Pattern and color of finishes and fabrics for panels [and spine walls], components, and trim shall be [in accordance
with Section 09 06 90 COLOR SCHEDULE] [as shown on the drawings] [_____].

2.9.3 Power Distribution
<AST/>
NOTE: The 8-wire system is currently the most common system utilized for applications
serving mixed loads including electronic data processing equipment. This is
available in several configruations from which to choose. Since EDP equipment
generates high levels of harmonics (* see footnote below), a full size neutral
should be provided for each EDP circuit. Alternately, it is recommended that
the phase conductor not be loaded to more than 12A or that an oversized neutral
be specified. To minimize interference from electronic noise to sensitive data
processing components, the EDP equipment should be placed on the dedicated circuits.
In the absence of other criteria, use of an isolated ground conductor is not
recommended for the EDP circuits (See IEEE Std. 1100). If the amount of EDP
load is extensive and the conventional load is minimal, a modified 8-wire system
should be provided.
Non-linear loads such as computers, copiers, laser printers, electronic lighting
ballasts, and uninterruptible power supplies cause harmonic distortion on power
distribution systems. The majority of workstation loads are non-linear, harmonic
producing loads. Designers must ensure that the building power distribution
equipment can support these non-linear loads. IEEE Std 519 and 1100 provide
details concerning the causes, effects, and means of compensation for non-linear,
harmonic producing loads on power systems. Harmonic compensation may include,
but is not limited to: specifying K-rated transformers, derating transformers,
oversizing neutrals to 200 percent of the ampacity of the phase conductors or
phase bus, using phase conductors and terminals with higher ampacities and/or
higher temperature ratings, supplying non-linear loads from dedicated isolation
transformers, and installing shunt filters. See UGGS-16415A for further guidance.
Surge suppression and power conditioning receptacle modules are available.
However power conditioning for specific loads (particularly portable equipment)
is normally a User responsibility and is not provided as part of the construction
contract. The Air Force has identified specific responsibilities of the user
and suppliers of end-use equipment. (See Air Force ETL 89-6 for specific criteria
or verify specific requirements for electrical support.)
<AST/>

[power][ and ][communications] raceway and the capability of disconnecting and connecting external circuits to
the electrified raceway in the panel[ and ][spine wall]. The communications receiving raceway shall have capacity
for at least [six][twelve][twenty] 4-pair category 5 cables. Power and communications wiring may share a common
wireway if a metal divider is included to ensure electrical isolation. Doors or access openings shall be included
for entry of communications cable. The electrified power raceway shall be of the [8-wire][6-wire][ or ][5-wire]
configuration indicated.[ Unless otherwise indicated, conductors of the 8-wire system shall be allocated as
follows: the three-phase system shall have one equipment ground, one isolated ground, [one neutral] [one oversized
(133 percent minimum) neutral], and two each dedicated phase.] [Unless otherwise indicated, conductors of the

commercial grade conforming to NEMA WD 1 and NEMA WD 6. If receptacles are not interchangeable or will not permit
field adjustment of phase and circuit selection, 10 percent spare devices of each type shown on these plans shall
be provided. [All][General use] receptacles shall be of the duplex configuration; unless otherwise indicated,
special use receptacles shall be of the simplex configuration with the blade/pin arrangement identified on the
plans. Coordinate the color of receptacle bodies with the color of the panel [and spine wall] trim. Isolated
ground receptacles shall [be orange] [or] [have distinct markings] [be of a different color than other receptacles].
Field applied identification shall be permanent; stick-on or non-setting adhesives shall not be used. The contractor
shall provide [5][_____] percent spare devices for each configuration and type of receptacle. A minimum of [5][_____]
receptacle removal tools shall be provided for systems that require special tools for proper receptacle removal.
2.9.3.2 Power Cabling Variations
The paragraph Power Distribution has identified specific cabling configurations. Since universal conventions
have not been established, variant configurations available from various manufacturers will be considered. Alternates
shall allow the same circuiting, device connections, neutral and ground separation, and upstream feeder connections
as shown on the plans. Variations shall be approved in advance. See paragraph ALTERNATE DESIGN. An example
of an acceptable variation includes the use of a manufacturer's configuration which allocates individual conductors
differently, but which has the same quantity of conductors and allows devices to be physically connected in the
field as shown on the plans. It is not necessary that the manufacturer's labeling codes or terminology match
the designations used on project plans or in the specifications; however, neutrals and grounds shall have insulation
color coded per standard practice or be provided with tags, colored tape, colored ribbons or similar identification.
(The reference to "dedicated" conductors in this specification pertains to circuit connections upstream and load
connections downstream of panels; it is not necessary that manufacturer's designations correspond.)
2.9.4 Electrical Connections
<AST/>
NOTE: The direct wired configurations should be suitable for most applications.
All wiring should be contained within raceways or wireways. The exposed cord/plug
arrangement should not be used, unless specifically requested by the user.
If used, ensure that the design conforms to the limitations of Article 605-8
of NFPA 70.
Code-enforcing personnel in some areas require separate hard wired junction
box interfaces from building services to furniture system installations. If
the facility will be under their jurisdiction, the design must conform and the
junction box configuration must be provided in lieu of the direct wired. If
the facility will not be under local jurisdiction, the direct wired configuration
could be provided per User request; however, it is preferred that the Government
design be consistent with local practice. If top entry service poles are used
for power interfacing, the junction box configuration is preferred for all locations.

indicated on the drawings.
2.9.8.1 Luminaire Configuration
<AST/>
NOTE: The lamp and ballast types should be indicated on the drawings. Use
of electronic ballasts and T8 lamps is strongly encouraged as a means of meeting
energy conversation goals for the building. Although there are no national
standards for electronic ballasts, technical requirements are covered in Section
26 20 00 INTERIOR DISTRIBUTION SYSTEM. Electronic ballasts are the most efficient
fluorescent ballasts, eliminate visual flicker and are quiet. When used, the
electrical design must consider the harmonics and electromagnetic energy generated
by these ballasts. Specific areas which should not have electronic ballasts
are medical electronic equipment areas and areas equipped with infrared remote
control or security devices. It is important to inform Users of the benefits
and risks of electronic ballasts and to involve them in the decision regarding
their use.
<AST/>
Luminaires and lamps shall be as specified in Section 26 51 00 INTERIOR LIGHTING and as modified herein. Luminaires
shall be linear, circular, or compact fluorescent type and shall have prismatic lenses, baffles, or other shielding
device configured to minimize glare by shielding the lamp from the view of a seated user. Provide a built-in
reflector. Task lights for each workstation shall provide a minimum of [810] [650] lx [75] [60] foot candles
of light (horizontally measured), without veiling reflections, on the work surface directly below and a maximum
of 500 mm 20 inches from the luminaire.[ Personal luminaires (non-undercabinet type) shall be constructed of
aluminum and plastic. The luminaire shall articulate at three distinct joints. The minimum adjustable arm range
shall be 10 inches. The luminaire shall be [slat tile mounted][desk mounted][panel mounted][freestanding][_____].]
All diffusers, grilles or other coverings shall be easily removable to permit cleaning and relamping. Provide
luminaires with energy efficient ballasts and lamps as indicated. If the type is not identified on the plans,
F32T8 lamps in 1220 mm 4 foot units with high frequency electronic ballasts shall be used. Each luminaire shall
have an easily accessible on-off switch and one rapid-start ballast. A variable intensity control is acceptable
if the low setting is equivalent to "off" with zero energy consumption. Multiple switching is also acceptable.
Ganged luminaires or shared ballasts shall not be used. Lamps and ballasts shall conform to the requirements
of Section 26 20 00 INTERIOR DISTRIBUTION SYSTEM.
2.9.8.2 Wiring
<AST/>
NOTE: If the facility will be under the jurisdiction of a city code, verify
requirements. Some locations require hard wired connections.
<AST/>
Each luminaire shall have a 1830 mm6 foot minimum, factory installed, heavy duty electrical cordset with a grounded
plug for luminaries that are mounted on the same wall as the receptacle. Luminaires mounted on non-powered wall
shall have a 2743 mm9 foot minimum, factory installed heavy duty electrical cordset with a grounded plug. Direct
or hard wire connections are not acceptable. Unless otherwise indicated, cords shall be concealed. Cord concealment
shall be built-in within panels [and spine walls] or shall utilize field installed, manufacturer approved accessories.
Cords may be extended through dedicated channels located at any point within panels [and spine walls] or may
be placed in vertical slots or in the space between panels [and spine walls] if held in place by retainers and
concealed by a cover plate. Vertical wire managers shall be prefinished and cut to size and shall extend from
the task light level down to the top of the work surface below the task light. Each manager shall be attached
to a panel vertical edge or connector strip without damage to the surfaces.
2.9.9 Communications
Communications wiring shall be extended to, and installed in, the electrified panels [and spine walls] as shown
on the plans. Communications jacks shall be installed at designated locations.[ Provide a communication consolidation
point at the end of the cubicle. The consolidation point shall consist of a [24][48] port patch panel that is
rated for Category [5][5e]. The panel that covers the consolidation panel shall be lockable. All locks shall
be keyed alike. these locks shall not be keyed the same as any other item associated with the workstations.]
Communications work may be performed in conjunction with the installation of workstations or may be separately
executed at the Contractor's option; however, equipment, materials, and installation shall conform to the requirements
of [Section 26 20 00 INTERIOR DISTRIBUTION SYSTEM] [Section 27 10 00 BUILDING TELECOMMUNICATIONS CABLING SYSTEM]
[_____] and all interfaces shall be properly coordinated.
2.9.10 Special Systems
<AST/>
NOTE: Include this paragraph only in projects where requirements for shielded
facilities (TEMPEST, Red/Black, EMP, etc.) and secure wiring have been called
out in project criteria. Specific requirements for cable arrangement, separation
of Red/Black lines, etc., need to be verified for each project. Provide metal
raceway, channels, etc. throughout. Separation distances required for exposed
cable or wiring in nonmetallic raceways are much greater than for wiring installed
in totally enclosed metal raceway. Site specific details and/or notes should
be prepared for each project.
<AST/>
Designated raceway systems shall provide management for secure and nonsecure power, computer and telecommunications
cabling. Secure distribution shall be separated from nonsecure distribution [in accordance with details shown
on the plans] [by running secure lines along top located raceway and nonsecure along the bottom of the workstation
panel [and spine wall]].
