PART 1:       GENERAL

1.01        RELATED SECTIONS

                A.            Section 018110 – Green Building Guidelines

1.02        INTENT AND BACKGROUND

A.            The intent of this standard is to establish a benchmark standard of quality for all carpet installed in Cornell University buildings. 

B.            This standard addresses the minimum acceptable quality of carpeting for general use in medium to heavy traffic areas such as classrooms, student spaces and administration offices.  For extra traffic or special use (i.e. low static - computer) areas consult with Facilities Engineering to determine an appropriate specification.

C.            Acceptable carpet shall comply with all current building codes at the time of purchase and installation.

D.            Installation practices shall conform to manufacturer’s recommendations and industry standards “Best Practices” in all cases.

E.            Use of broadloom carpet shall only be used in areas of low traffic or highly specific designed areas.   When carpet is used, carpet tile is the preferred product and attic stock should be incorporated into the project.

1.03        OBJECTIVES

A.            Cornell desires a high quality carpet product that meets the functional, aesthetic and fiscal needs of the University and supports the University’s commitment to sustainability.

B.            A wide range of styles and colors should be available at locked, high-volume contract pricing.

1.04        ROLES AND RESPONSIBILITIES

A.            This standard should be considered alongside Cornell Design and Construction Standard 018110 – Green Building Guidelines, which require all new buildings and major renovations to meet LEED/30 standards.  Specific items that could potentially affect the selection of carpet products under the requirements of this standard include minimum recycled content, recyclability of the product after its useful lifespan, life cycle costs and construction waste reduction.

B.            Approved Cornell University preferred carpet manufacturer, local distributors and installers shall be used.  Check with Cornell’s Office of Supply Management for current approved installers.  On capital projects that are bid, the preferred carpet manufacturer should be the basis of design. (Currently Interface and J+J Flooring Group)

PART 2: PRODUCT REQUIREMENTS

2.01        GENERAL

The following items apply to both tile and broadloom carpet products:

A.            Aesthetics:  Carpet colors are to be of a serviceable mixture such as tweeds, multi-colored combinations, or monochromatic color combinations.  This is especially important in high-traffic, high-stain areas.  Solid color carpeting is not preferred.

B.            Mergeability:  Carpet that is of same style/color, but from different dye lots and/or manufacturing dates, must be able to be merged and used interchangeably, both at initial installation and at later selective replacement, to create a continuous carpeted surface.

C.            Warrantee:  20 year full term, non-prorated period:

             No edge ravel, zippering, backing separation, shrinking, stretching and static electricity.

             Secondary Backing will not delaminate.

             No more than 10% face yarn loss.

             Will maintain tuft bind wet or dry.

             Carpet should not require the use of chair pads.

             The stain resistant properties of the fiber must be permanent and cannot be removed by commercial cleanings or abrasive wear.  Products are free of perfluorinated (PFC) stain resistance treatments.

             Modular tile will remain dimensionally stable and not cup, dome or dish under normal use.

             Mergeable dye lots – product must be able to be replaced without visual recognition.

             Will maintain anti-microbial effectiveness.

             10 year warrantee on installation.

D.            Minimum Performance Standards:

National Voluntary Laboratory Accreditation Program (NVLAP) certified test results that meet or exceed the following testing requirements:

             Flammability (Pill) Test (CPSC FF 1-70)

             Flooring Radiant Panel (ASTM E-648) Class 1

             Smoke Density Test (ASTM E-662)  450

             Static Generation Electrostatic Propensity (AATCC-134) Under 3.0kV

             Color fastness to Light (AATCC 16-E) AATCC grey scale for color change minimum of 4 or better after 60 AFUS for solution dyed yarns.

             Carpet tile only:  Dimensional Stability (Aachen Method ISO 2551) _less than 0.1%

2.04        ADHESIVES

A.            Concern for safe and healthy environments in Cornell facilities has prompted the adoption of very stringent standards requiring the use of quality, non-toxic adhesives for carpet installations.  The manufacturer and products listed below have been determined to be acceptable adhesives for carpet installation in campus buildings.  This approval is proprietary and specific to the manufacturer and products listed.  Selection and appropriate use in given applications is at the discretion and responsibility of the installer.  Such approval will in no way preclude the requirements to provide a Material Safety Data Sheet (MSDS A1000, A10001, A1100, A11001, A2000, A2001, A2100, A21001) for all materials used on installations.  “Or equal” substitution of adhesives must be approved in writing and submitted with all evaluation data before being bid or used for campus applications.
