Division 9 Finishes
- Extravagant, costly and/or high maintenance finishes should be avoided.
- CPCC must approve the color selections of all finishes.
- Finishes that have minimal tolerances and place unrealistic expectations on the installing contractor(s) should be avoided.
- All finish materials shall be evaluated on five levels. No one factor shall be evaluated solely:
- Initial Cost
- Life cycle cost, ease of repair
- Contribution to the aesthetics/use of the space
- Contribution to the sustainability to the environment
- Compliance to accessibility and ADA
Gypsum Wall Board
- Provide 5/8” minimum thickness
- Specify and check during construction that the GWB is installed close to (1/4” max.) the floor slab. Otherwise, if there is a significant gap, the rubber base is installed and gets pushed in later by the vacum cleaner or furniture and becomes unsightly.
Ceramics and Quarry Tile
- Floor Tile; 12” x 12”, or 8" x 8" (6” x 6” min.) porcelain ceramic tile. Large floor areas should have a subtle pattern of different colors. Avoid intricate patterns or patterns with stark contrasts.
- Wall Tile; 4-1/2" x 4-1/2" glazed ceramic tile equal to Dal-Tile Glazed Interior Wall Tile by Dal-Tile Corporation. Standard Grade quality conforming to ANSI 137.1-1980.
- Quarry Tile Care; In instances where quarry tile is specified as the building floor covering, the Contractor will clean the quarry tile floor with Hillyard Seal - 341 or approved equal. Colors selected shall minimize the showing of dust and/or footprints.
Suspended Acoustical Ceilings
- Acoustical Tile; (general use) 2' x 2' x 3/4", non-directional, mineral board lay-in panels, tegular edge, equal to Armstrong # 1820 fine fissured with NRC .70 and light reflectance .84
- Other Ceilings are acceptable such as painted GWB and painted exposed structure. Avoid exposed structure treatment in instructional spaces unless special treatment is provided (acoustical deck, quiet ductwork, etc) so that the instructor has a quiet space to teach in.
- Suspended Grid; Heavy duty, double web, exposed grid system, prefinished 15/16 inch wide by Armstrong, Donn, or Chicago Mettalic.
- Avoid creating code situations where the suspended acoustical ceiling system is part of a required rated assembly. Any proposed rated acoustical ceilings must receive prior approval from the Construction Director before proceeding with the contract documents.
- On significant renovation or demolition projects, Designer shall determine with the Owner if the old ceiling tile can be recycled. Armstrong World Industries has developed a program that will pay the cost of shipping old ceiling tiles to its plant for reuse.
- First, the Owner will need to determine what the old ceiling tiles are and call the Armstrong recycling program at 1-888-CEILINGS to get qualified and understand the specific logistics.
- Once qualified, the Contractor removes the ceiling tiles and stacks the tiles on wood pallets and wraps them up.
- Armstrong will arrange for a truck to pick up the material.
- Floor Tile; Vinyl composition, 1/8" x 12" x 12", as manufactured by Kentile, Armstrong or equal, meeting or exceeding Federal Specification #SF-T-321 B, Type 4. Colors selected shall minimize the showing of dust and/or footprints (no all black or all white floors). Large floor areas should have a subtle pattern of different colors. Avoid intricate patterns or patterns with stark contrasts.
Designers must specify that the concrete substrate be tested for moisture and insist on receipt of the test results prior to the vinyl tile installation. One common test that Armstrong recommends is an ASTM F1869-98 Standard test method for measuring moisture vapor emission rate of a concrete subfloor using anhydrous calcium chloride.
- Base; Rubber cove base, 4", as manufactured by Roppe Rubber, Johnsonite Rubber Company, Flexco, or equal, meeting or exceeding Federal Specification #SF-W-40A, Type 1. Use premoulded corners.
There are other acceptable floor coverings such as terrazzo, thinset epoxy terrazzo, seamless vinyl flooring, etc. Avoid the use of marmoleum. Large floor areas should have a subtle pattern of different colors. Avoid intricate patterns or patterns with stark contrasts.
Specify carpet that meets the following characteristics. Avoid carpet allowances in the contract documents.
- The NC Department of Administration Purchase and Contract Division has developed a Qualified Products List (QPL) of carpets generally used by public schools, community colleges, and universities. Unless there is a special requirement to deviate from this list, the Designer is requested to use the QPL list as a resource for specifing carpet for CPCC. Refer to the QPL for Carpet and whenever possible, specify a recycled and/or recyclable carpet from the QPL 7720-38, Class 3 (or higher) list.
- Generally all carpet shall be a 100% nylon loop pile with a minimum face weight of 28 oz., with a 10 year warranty. Nylon 6 or 6.6 branded, dye system solution dye.
- Offices and Conference rooms: Backing needs to be at least a High Tuft Bind Synthetic: primary backing of woven polpropylene standard performance with a 10 year warranty.
- Corridors, Classrooms, high traffic areas: In areas that could become wet, provide a high performance moisture barrier backing with a lifetime warranty against delamination and edge ravel.
- Carpet construction shall be an anti-microbal dense textured loop with a gauge of 1/8 minimum (1/10 preferred). Stitch rate: 8 or 10 per inch. Pile height: .013 to .015. Face yarn weight: 28 oz. minimum, anti-microbal.
- Specify a patterened carpet, textured loop graphics, or at least a 4-ply tweed pattern. Avoid 3-ply heather tweeds or other inexpensive carpets that will not hide dirt.
- The CPCC standard furniture is a neutral color. The floor plane is an opportunity to introduce some color. Differentiate floor colors from function to function, or differentiate floor colors from floor to floor in a multi-story building.
- Limit the amount of exterior finishes that require painting.
- Interior paint on GWB shall have an eggshell finish
- Interior paint on CMU shall have an eggshell finish over block filler.
- Avoid the use of variegated wall coverings such as Zolotone.
- Fabric wrapped panels may be specified in special spaces with high acoustical needs, such as: Large lecture/auditorium, Boardroom, Video-Conferencing room, etc.. Panels are fabric covered and have a ¾” thick fiberglass blanket core with extruded PVC edges.
- Vinyl wall covering may also be specified in special spaces and specified as an ADD Alternate in the Classrooms under a chair rail. Specify 21 ounce weight minimum. Other durable materials under a chair rail in the classroom will be considered.
