Where floor coverings are by the access floor manufacturer, the type, color and pattern shall be selected from manufacturer s standard. All areas to be furnished with laminated floor panels must be maintained at ambient temperature between 50 to 90 F and at humidity level between 20% to 80% relative and shall remain within these ranges through installation and occupancy. B. High-pressure laminate floor covering shall meet requirements of NEMA LD3, and shall conform with one of the following grades: Grade HDH (1/8 / 3.0mm) or Grade HDM (1/16 / 1.5mm). C. High-pressure laminate floor coverings shall have an edge condition that is integral to the tile. Separate edge trim pieces are not acceptable. D.

Examine structural subfloor for unevenness, irregularities and dampness that would affect the quality and execution of the work. Do not proceed with installation until structural floor surfaces are level, clean, and dry as completed by others. B. Concrete sealers, if used, shall be identified and proven to be compatible with pedestal adhesive. Verify that adhesive achieves bond to slab before commencing work. C. Verify dimensions on contract drawings, including level of interfaces including abutting floor, ledges and doorsills. D. The General Contractor shall provide clear access, dry subfloor area free of construction debris and other trades throughout installation of access floor system. Page 14 Data Center R09/12

15 E. Area to receive and store access floor materials shall be enclosed and maintained at ambient temperatures between 35 to 95 F and relative humidity levels between 20 to 80%. At least 24 hrs. before installation begins, all floor panels shall be stored at ambient temperatures between 50 to 90 F and relative humidity levels between 20% to 80% and shall remain within these environmental limits throughout occupancy. 3.2 Installation A. Pedestal locations shall be established from approved shop drawings so that mechanical and electrical work can be installed without interfering with pedestal installation. B. Installation of access floor shall be coordinated with other trades to maintain the integrity of the installed system. All traffic on access floor shall be controlled by access floor installer. No traffic but that of access floor installers shall be permitted on any floor area for 24 hours to allow the pedestal adhesive to set. Access floor panels shall not be removed by other trades for 72 hours after their installation. C. Floor system and accessories shall be installed under the supervision of the manufacturer s authorized representative and according to manufacturer s recommendations. D. No dust or debris producing operations by other trades shall be allowed in areas where access floor is being installed to ensure proper bonding of pedestals to subfloor. E. Access floor installer shall keep the subfloor broom clean as installation progresses. F. Partially complete floors shall be braced against shifting to maintain the integrity of the installed system where required. G. Additional pedestals as needed shall support panels where floor is disrupted by columns, walls, and cutouts. H. Understructure shall be aligned such that all uncut panels are interchangeable and fit snugly but do not bind when placed in alternate positions. I. Finished floor shall be level, not varying more than inches (1.57 mm) 10 feet (3 m) or overall. J. Acceptance: General contractor shall accept floor in whole or in part prior to allowing use by other trades. ### End ### Page 15 Data Center R09/12
