PART 3    EXECUTION
3.1	EXAMINATION
A.	Do not begin installation until substrates have been properly prepared.
B.	If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
3.2	PREPARATION
A.	Clean surfaces thoroughly prior to installation.
B.	Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
1.	Confirm pedestal size selected does not exceed compressive strength of pedestal supporting substrate.
3.3	INSTALLATION
3.4	Leveling Plate Requirements: Shimming adjustment requires, approx. 10 leveling plates per 100 pedestals. Irregular deck surfaces or pavers of varying thickness increase number required.
A.	Install in accordance with manufacturer's instructions.
B.	Horizontal Leveling: On deck areas where a dead level paver surface is required, full shimming with leveling plates and multiple stacking of pedestals shall be utilized.
C.	Method:
1.	On deck perimeter and around protrusions where it is not practical to cut pavers to fit (i.e. canted roof-wall junctures), coarse gravel with binder (if required) shall be used in voids.
2.	Following predetermined layout, locate first row of paver stones at an exterior edge of deck, using 1/2 pedestals at edges and 1/4 pedestals at corners and at partial angled paver locations.
3.	Place pedestals with projecting ribs facing upwards to ensure uniform paver stone joint spacing. Place pavers tight to spacer ribs to ensure even spacing.
4.	Place paver stones by lowering horizontally rather than nosing into position to eliminate possible indentation of substrate.
5.	Align and shim as required as work progresses. Vertical difference between pavers for walking surfaces shall not exceed 1/8 inch (3 mm).
6.	Run subsequent rows of pavers parallel to first row.
7.	Where multiple stacking of pedestals is employed, locate leveling plates on top of upper pedestal, never in-between or below pedestals.
3.5	PROTECTION
A.	Protect installed products until completion of project.
B.	Touch-up, repair or replace damaged products before Substantial Completion.
