Setting of Support Pedestal units signifies acceptance of building roof membrane and <br />protection board substrates. <br />3.2 PREPARATION <br />A. Keep area where Roof Paver Pedestal System is to be constructed free from nails, screws, <br />debris, etc. during entire job. Repair all damage to roof substrate. <br />B. Complete construction of all roof drain inlets and other drainage structures before the <br />commencement of Support Pedestal System installation. <br />C. Do not damage roof drains, roof substrate, and/or other drainage appurtenances during <br />installation. Report all damage immediately. <br />D. Protect HVAC, ventilation pipes and other structures during Roof Concrete Paver and Support <br />Pedestal System installation. <br />E. Clean and free projections and debris impairing the performance of the pedestals or the total <br />system from the substrate. <br />F. Establish accurate lines, levels and pattern. <br />G. G. Installation requirements vary for each individual project site. Provide Roof Concrete Pavers <br />materials used, pattern, grid layout, starting point, and finished elevation on plan view shop <br />drawings which have been prepared and approved. <br />H. Establish a starting point and the finished elevation of the Roof Concrete Paver surface. Mark <br />the Support Pedestal System elevation (finished elevation minus paver material thickness) <br />around the perimeter using a transit "torpedo" water level or laser leveling device. <br />L Define the paver surface area by accurately taking precise measurements. Mark off and square <br />all outside edges with control lines (chalk lines or spray paint). Install two (2) lines that are <br />perpendicular to each other across the paver surface area. Continue to mark a grid of lines in <br />both directions marking the location of each pedestal. Implement control lines as references to <br />periodically check the layout during installation to assure a square layout. <br />3.3 INSTALLATION <br />A. PEDESTAL SYSTEM <br />Install in accordance with manufacturer's instructions. <br />2. If required, place a Floating Insulation Base (FIB) board or Floating Foundation Base <br />(FFB) in the location on the grid of each pedestal. <br />3. Place a Support Pedestal where each measured grid line meets the perimeter. <br />a. Remove two (2) spacer tabs in line with one another on top of each pedestal <br />placed around the perimeter. <br />b. Remove all four (4) spacer tabs at corners. <br />4. Adjust each Support Pedestal to a "top of pedestal" elevation marked around the <br />perimeter. (Normally the deck support is positioned as close to the perimeter as possible, <br />with the two remaining spacer tabs aligned with the grid line.)
