PART 3 EXECUTION

3.1 EXAMINATION AND PREPARATION

A. Prepare substrates using the methods recommended by the manufacturer for achieving best result for the substrates under project conditions. Verify elevations, pedestal heights and layouts. Establish accurate and level lines and patterns1. Substrate Requirements: Laid at ground or roof level over concrete, screed, EPDM,

rubber, single ply or other built up roofing systems, or directly over insulation materials, dependent on insulation densities and overall loadings.

B. Do not proceed with installation until substrates have been prepared using the methods recommended by the manufacturer and deviations from manufacturer's recommended tolerances are corrected. Commencement of installation constitutes acceptance of conditions.

C. If preparation is the responsibility of another installer, notify Architect in writing of deviations from manufacturer's recommended installation tolerances and conditions.

3.2 INSTALLATION

A. Install roof decking pedestals in accordance with manufacturer's recommendations. Securely place base supports at locations shown on shop drawings.

B. Locate pedestals at the proper elevation and placed in position prior to the installation of roof decking pavers.

C. Level Installation: Establish starting point and finished elevation of the roof decking paver surface, and determine the pedestal head support elevation by subtracting the thickness of the paver. Mark around the perimeter using transit, or laser leveling device.

D. Slope Compensation: Mount slope corrector to the pedestal head with fixing clips and set slope by rotating the mechanism through 360 degrees to the desired value. Adjust slope in increments of 0.5% up to a maximum 5% slope. Lock slope corrector as per manufacturer's recommendations to create a level and plumb paver surface.

E. Perimeter Containment: Provide field installed restraint, where roof decking is not constrained by an abutting wall. No movement shall be allowed at the perimeter of the roof decking greater than 3mm (1/8 inch).

F. Make final slight adjustments to pedestals as they are fully loaded by roof decking pavers.

G. Level each succeeding row of pedestals as the roof decking paver installation proceeds.

07 76 16-15

H. Ensure roof decking pedestals are maintained in a straight and consistent pattern and that installed deck pavers are level and do not rock back-and-forth under loading.

I. At roof deck access points for pedestrians, ensure that pavers are level and that the walking surface does not have randomly raised or uneven joints creating a tripping or safety hazard.

3.3 ADJUSTMENT AND PROTECTION

A. Adjustment: Eliminate rocking and uneven pavers; rotate pedestals for final adjustment after fully loaded.

B. Touch-up, repair or replace damaged products before Substantial Completion.

C. Protection: Protect installed products and finishes from damage during construction.
