I.1 Flooring

I.1.1 CARPET

Use the standard field carpet in all typical office areas.  Accent carpet and carpet borders are to be used in officer suites, conference rooms, corridors, and lobbies.  The accent carpet or a carpet border may be used in other areas if approved by the DPW. 

A minimum of 6’ of walk off carpet is to be used at all doors accessing the exterior where carpet is used inside the door.  Walk off mats are to be used at all exterior doors where a material other than carpet is used inside the door.

Provide 5% minimum overstock for future modifications.

Mohawk direct glue down carpet (or equal) (GS-OOF-84404) is recommended.

I.1.1.1 Guidance, Warranties, and Requirements

All carpet must meet the criteria set forth in ? Is there an army standard for carpet?.

LEED™ provides credits in the Material sand Resources as well as the Indoor Environment Quality categories for sustainable options that could be relevant to carpet and adhesive selection.  More details on sustainable carpet selection are provided below in Section I.1.1.4 Sustainability.

I.1.1.2 Type/Size Requirements

24” square carpet tiles are preferred.

6’ or 12’ rolled goods are acceptable in low traffic areas like office and conference areas.

I.1.1.3 Quality Considerations

 Different height carpets next to each other are generally inappropriate; proper preparation and consideration must be given to resolve this prior to installation.

Brand name continuous nylon fibers will wear better and provide more resilience than those made from polyester, acrylic, or olefin fibers.

Staple fibers are not allowed.

I.1.1.4 Sustainability

Whenever possible, sustainable carpet materials must be used.  Sustainable properties of carpet that should be considered are:

Recycled content:  either industrial waste and/or post consumer waste.

Recyclability of the product at the end of its life.

Yarn fiber type and dye method.

Proper cushion/padding material will extend the carpet life.

Expected life cycle for carpet as a whole.

Reduction or absolution of toxic chemicals, VOCs, and pollutant emissions.

I.1.1.5 Cushions/Padding

All carpet shall have an attached cushion/padding such as on carpet tiles or cushion/padding should be added to 12’ rolled goods.

All carpet shall meet all ADA requirements.  Maximum pile thickness shall not be more than ½” thick.

I.1.1.6 Use and Selection

See charts in the Interior portion of Section 8 for locations and instances where carpet is an acceptable flooring material.

Carpet on stairs is not recommended.  Other more durable material should be used, i.e., rubber treads.

I.1.1.7 Solid Colored Carpet

Solid color carpeting is to be used sparingly.  If solid color carpet is installed, it should be installed so the “hand” is always in the same direction.  Solid color carpet can be used as an accent or border carpet.  If an entire room of solid colored carpet is to be installed rolled goods are preferred over carpet tiles.

I.1.1.8 Pattern Selection

Patterned carpets are preferred.  Patterns help to “mask” soiling in traffic areas.  Use only patterned carpets with distinguishable designs and patterns.  Patterned carpet should be multi-colored with three or more colors, not just shades of the same color.
