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 patterns
1.
Substrate Requirements: Laid at ground or roof level over concrete, screed, EPDM,
07 76 16-11
rubber, single ply or other built up roofing systems, or directly over insulation
materials, dependent on insulation densities and overall loadings.
3.2
3.3
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.
INSTALLATION
A.
Install products in accordance with manufacturer's instructions.
1.
For Water Run-Off: Minimum slope of 2 percent.
2.
Larger Applications: Manufacturer recommends pedestals be pre-sorted and pre-set
to proper elevation and placed in position prior to installation of decking.
3.
Limitations: Pedestal system shall not be used for decks over which wheeled or
vibrating machinery are to be used.
4.
Point Loads: Such as planters, seating, furniture or heavy objects should be
supported by additional pedestals.
B.
Perimeter Containment: Sections of decking not restrained by parapet or foundation wall
must be ' boxed-in' and contained by manufacturer approved perimeter containment.
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.
