PART 3 EXECUTION

3.01 EXAMINATION

A. Verify that subfloor surfaces are smooth and flat within the tolerances specified for that type of work and are ready to receive carpet.

C. Cementitious Sub-floor Surfaces: Verify that substrates have fully cured and ready for flooring installation by testing for moisture, alkalinity (pH) and compression strength.

1. Test as Follows:

a. Alkalinity (pH): ASTM F710.

b. Internal Relative Humidity: ASTM F2170.

c. Moisture Vapor Emission: ASTM F1869.

2. Obtain instructions if test results are not within limits recommended by flooring material manufacturer and adhesive materials manufacturer.

3. Verify cementitous sub-floor and any fillers have reached minimum 3000 psi strength.

D. Verify that required floor-mounted utilities are in correct location.
