PART 3 - EXECUTION

3.01 CARPET REMOVAL

A. Remove and dispose of all existing carpet and materials to make subfloor acceptable for installation if applicable.

3.02 INSPECTION

A. General: Do not start work until work of other trades are substantially completed. Inspect surfaces to receive carpet and verify that all such work is complete to the point where this installation may properly commence. In the event of discrepancy, notify Construction Manager. Do not proceed with installation in areas of discrepancy until all such discrepancies have been fully resolved. Start of carpet installation indicates acceptance of subfloor conditions and full responsibility for completed work.

3.03 INSTALLATION, GENERAL

A. General: Comply with manufacturer's instructions and recommendations for installation of this type of carpet.

B. Prepare the subfloor to ensure a successful installation as directed in carpet manufacturer’s published installation guidelines.

C. Employ use of manufacturer’s recommended adhesive that requires no subfloor moisture testing when installed with standard adhesive and the slab meets ASTM F-710 including proof of the presence of an intact moisture vapor retarder per ASTM E-1745 (Class B or Better) in direct contact with the concrete slab, no standing water, no free liquids present, no evidence of moisture staining, no hydrostatic pressure, and a pH level that does not exceed 12. For all other conditions or when the above requirements are not met, the limits are in-situ relative humidity (maximum RH 95% per ASTM F-2170) and/or moisture vapor emissions (maximum 10 lbs./1,000 SF/24 hrs. per ASTM F-1869).

D. On-grade and below-grade concrete slabs must have an approved vapor retarder (ASTM E-1745) which is properly installed (ASTM E-1643).

E. Carpeting shall be installed in the format recommended by manufacturer or at owner’s approval.

Cut carpet tile evenly and accurately to fit neatly at walls, columns, and projections. Extend carpet under open-bottomed and raised-bottom obstructions, and under removable flanges of obstructions.

F. Installed carpet tiles shall be free from ripples, ravels, frays, and puckers. All loop pile carpets will demonstrate some fuzzy edges due to normal manufacturing conditions. Tractor tile joints and trim fuzzy edges or loop blossoms after installation.

G. Expansion Joints: Do not bridge building expansion joints with continuous carpeting; provide for movement.

3.05 CLEANING AND PROTECTION

A. Remove and dispose of debris and unusable scraps.

B. Vacuum carpet using two motor, top loading, upright commercial machine with brush-only element, utilizing a high filtration dust bag. Remove spots in accordance with carpet manufacturer’s guidelines and replace carpet where spots cannot be removed. Remove any protruding face yarn using sharp scissors. Be certain to trim any loose yarns or fibers at all seams.

C. Following cleaning and vacuum carefully protect the carpeting from soiling and damage until final acceptance. Protection shall be accomplished by using approved protection paper. Edges shall be lapped 6 inches and secured with non-asphaltic tape. Covering shall be kept in repair and damaged portions replaced during the construction and move-in period.

D. Maintenance Materials: Deliver usable scraps to Owner's designated storage space, properly packaged and identified. Dispose of smaller pieces as construction waste.
