PART 3 EXECUTION

3.1 INSTALLATION

Install access flooring at the location and elevation and in the arrangement shown in the Instruments of Service. The floor system must be low-profile access floor system consisting of a series of modular removable, interchangeable units,, complete with all supplemental items, and be the standard product of a manufacturer specializing in access flooring systems.

Install the floor system in accordance with the manufacturer's instructions. Open ends of the floor, where the floor system does not abut wall or other construction, must have positive anchorage and rigid support. Maintain areas to receive access flooring between 60 and 90 degrees F, and between 20 and 70 percent humidity for 24 hours prior to and during installation.

Examine substrates, with Installer and manufacturer's authorized representative present, for compliance with requirements for installation tolerances, surface irregularities, and other conditions affecting performance of the Work. Proceed with installation only after unsatisfactory conditions have been corrected.

a. Verify that substrates comply with tolerances, dimensioned clearances, and other requirements specified in other Sections and that substrates are clean, dry, and free of conditions and deleterious substances that might interfere with system installation.

b. Verify substrates comply with minimum subfloor flatness (FF) of 25 and subfloor levelness (FL) of 20.

c. Verify electrical boxes and openings are installed in accordance with Drawings, and approved Shop Drawings.

3.1.1 Preparation for Installation

Clear out all debris in the area in which the floor system is to be installed. Thoroughly clean structural floor surfaces and remove all dust. Install floor coatings, required for dust or vapor control, prior to installation. Unroll undersheet under access floor system Work area.

Ensure sheets are contiguous, without wrinkles, and edges butted.

a. Install adaptive cabling distribution access flooring and accessories in accordance with approved Shop Drawings and under supervision of adaptive cabling distribution access-flooring manufacturer's authorized representative to produce an installation that complies with performance requirements and is free of instability, rocking, rattles, and squeaks.

b. Install flooring and ramps securely in place and properly seated. Do not force components into place. Anchor ramps to concrete through each predrilled hole with appropriate screw anchors or comparable product.

c. Install border components to provide a close fit with adjoining construction, with voids between 1/2 and 3/4 inch (13 and 19 mm) where panels abut vertical surfaces.
