PART 3    EXECUTION
3.1	EXAMINATION
A.	Do not begin installation until substrates have been properly prepared and related work penetrating the plane of the roof is completed.
1.	Carefully inspect installed work of other trades and verify that such work is complete to the point where work of this section may properly commence.
2.	Notify the Architect in writing of the conditions detrimental to the proper and timely completion of work.
B.	Verify the Following:
1.	Substrates, membranes, and protection boards are ready for installation of pedestal and paver system.
2.	The roof deck will sustain the weight of the pedestal paver system.
3.	Deck dimensions and elevations and pedestal heights before commencing work.
3.2	PREPARATION
A.	Clean and prepare deck free of all debris in accordance with manufacturer's instructions.
B.	Install membrane protection layer under all pedestals if specified by roofing membrane manufacture.
C.	Establish accurate lines, levels, and pattern.
3.3	INSTALLATION
A.	Install in accordance with manufacturer's instructions, approved submittals, and in proper relationship with adjacent construction.
1.	Determine starting point and layout the paver and pedestal grid layout determining where full and cut pavers will be installed.
2.	Mark perpendicular guidelines on substrate surface to ensure square layout.
3.	Install initial pavers along guidelines forming a "T" pattern.
4.	Install Pavers tightly butted into pedestals. Form even joint width determined by pedestal spacer tabs.
5.	Checks shall be made constantly for correct elevation and spacing of the installed pavers using laser level, automatic leveler, or mason's line.
6.	Slight irregularities in paver thickness and/or deck heights can be compensated for by using one or more regulation shims.
7.	Any section of paver, pedestal or protection course which is not restrained by an abutting wall or parapet must be "boxed in" by some field installed restraint.
3.4	CLEANING AND PROTECTION
A.	Clean products in accordance with the manufacturers recommendations.
B.	Touch-up, repair or replace damaged products before Substantial Completion.
3.5	ROUTINE MAINTENANCE AND CARE
A.	Remove and replace pavers, which are loose, chipped, broken, stained or otherwise damaged. Make sure edge restraints stay intact and are structurally sound.
B.	Remove mortar stains and all other types of soiling from exposed paver surfaces, wash, and scrub clean.
C.	Efflorescence is a naturally occurring white residue or stain that is on the surface of new concrete. The residue will dissipate naturally with time.
D.	Provide final protection and maintain conditions in a manner acceptable to installation, which ensures paver work being without damage or deterioration at time of substantial completion.
E.	Joints and drains should be kept clean to protect from water back up.
