1.4.1 Physical Requirements

1 ***************************************************************************

1.4.2.1.1 NOTE: For each different type of carpet specified:

1.4.2.1.2 Use Table I at end of text to determine carpet wear classification.

1.4.2.1.3 Use Table II at end of text to determine minimum requirement for carpet construction necessary to meet the wear classification defined from Table I for the pile yarn type and pile fiber chosen. Insert surface texture, pile yarn type, pile fiber, finished pile yarn weight, pile density, width, gage, dye method, and attached cushion requirement as necessary for each carpet type. Pattern and color for each carpet shall be indicated in the drawings in the finish/color schedule. Designate each carpet with a letter or number symbol to key locations indicated in the finish/color schedule.

1.4.2.1.4 Specify carpet width and attached cushion requirement, if applicable. State carpet width as minimum permissible, bearing in mind that wider carpet minimizes number of seams. “Standard” width for most commercial carpet is 12 feet.

1.4.2.1.5 Some cushion-backed carpet is available in width of 6 feet.

1.4.2.1.6 Edit entire Part 2 to delete items that do not apply.

Vacuum the carpet until it is clean.

NOTE: Tables I and II shall be used to determine which type of carpet is appropriate for the facility being outfitted. Table I shall first be used to determine the carpet wear classification for the facility being outfitted. Then once this has been determined, Table II shall be used to determine the carpet construction necessary to meet the wear classification defined from Table I for the pile yarn type and pile fiber chosen.

NOTE: For Table I: Classifications are based on potential number of users, type of traffic, required appearance levels, and anticipated frequency of use. Multiple classifications are assigned where significant differences among similar facilities/areas are likely. The lowest classification shown determines minimum quality permissible for a given facility/area. Use higher classifications than minimum where indicated by potential usage conditions. Classification for stair carpet for all facilities is “SEVERE.”

14.4.4.1.2 The areas to receive resin grout must be clearly indicated on the drawings or defined in the specifications. Due to the higher cost of this grout, its use will generally be limited to areas such as:

14.5 Within the areas bounded by a line 600 mm (2 feet) outside of the trough areas for ranges, kettles, and ovens.

15 Within the areas of potwashing and dishwashing. In small kitchens where it may be impracticable to subdivide areas for grouting, resin grout method F114 or F133 may be used throughout.

15.4.4.1.1 For severe chemical exposure such as meat packing plants and photo labs, resin grout method F134 will be used throughout and a resin setting-bed will be required. Wherever resin setting-bed is used, the concrete slab will be steel-troweled finished to the final slope of the finished floor. The tile shall be set in a 3 mm (1/8 inch) thick layer of epoxy-or furan-resin mortar. When using furan resins, the concrete slab will be neutralized or painted in accordance with the resin manufacturer’s directions.

1.7.6.5.1 Ceramic Tile grout shall be prepared and installed in accordance with CS.

1.7.6.6 Installation of Marble Thresholds

NOTE: Where the top of tile floors will occur at a different elevation from the top of finished floors in adjoining spaces, provision for marble thresholds or saddles will be edited appropriately.

1.7.6.6.1 Thresholds shall be installed where indicated in a manner similar to that of the ceramic tile floor. Thresholds shall be the full width of the opening. Head joints at ends shall not exceed ¼ inch in width and shall be grouted full as specified for ceramic tile.

1.7.6.7 Expansion Joints

1 ***************************************************************************

1.9.13.2.1 Note: Expansion-joint details will be indicated on the drawings. Details as provided in TM 5-805-6 will be used as applicable. Location of expansion joints should, insofar as practical, be located outside the areas of tile finishes.

2 ***************************************************************************

1.7.6.7.1 Joints shall be formed as appropriate and per manufacturer’s recommendation.

1.7.6.8 Cleaning and Protecting

1.7.6.8.1 Completed tile surfaces shall be thoroughly cleaned in accordance with manufacturer’s approved cleaning instructions. Acid shall not be used for cleaning glazed tile. Floor tile with resinous grout or with factory mixed grout shall be cleaned in accordance with instructions of the grout manufacturer. After the grout has set, tile wall surfaces shall be given a protective coat of a non-corrosive soap or other approved method of protection.

1.8 WOOD FLOORING

NOTE: This guide specification covers the requirements for ceramic tile for walls and floors, porcelain tile, quarry tile, paver tile, and marble thresholds. Tile grouted with epoxy or furan resin is included, but quarry tile subject to severe chemical exposures is specified in Section 09330 CHEMICAL-RESISTANT QUARRY TILE.

Comments and suggestions on this guide specification are welcome and should be directed to the technical proponent of the specification. A listing of technical proponents, including their organization designation and telephone number, is on the Internet.

Recommended changes to a UFGS should be submitted as a Criteria Change Request (CCR).

Use of electronic communication is encouraged.

This guide specification includes tailoring options for floor tile, mosaic tile, quarry tile, detectable warning tile, porcelain tile glazed wall tile, and marble thresholds. Selection or deselection of a tailoring option will include or exclude that option in the section, but editing the resulting section to fit the project is still required.
