PART 3    EXECUTION
3.1	EXAMINATION
A.	Examine substrates, areas and conditions, with Installer present, for compliance with requirements for existing conditions, installation tolerances, and other conditions affecting performance of structural glass flooring.
1.	Verify that substrates comply with tolerances and other requirements specified in other Sections.
2.	Verify that pitch of 1/8 inch per foot is achievable.
3.	Proceed with installation only after unsatisfactory conditions have been corrected.
3.2	INSTALLATION
A.	Install glass flooring in accordance with manufacturer's instructions and approved submittals and the following:
1.	Do not use panels with chips, cracks, voids, discolorations, and other defects that might be visible in finished work.
2.	Rigidly secure non-movement joints.
3.	Install anchors with separators and isolators to prevent metal corrosion and electrolytic deterioration and to prevent impeding movement of moving joints.
4.	Seal joints watertight.
B.	Erection Tolerances: Install glass flooring systems to comply with the following maximum tolerances:
1.	Alignment: Limit offset from true alignment to 1/16 inch where surfaces abut in line, edge to edge, at corners, or where a reveal or protruding element separates aligned surfaces by less than 3 inches; otherwise, limit offset to 1/8 inch.
2.	Location and Plane: Limit variation from true location and plane to 1/8 inch in 12 feet but no greater than 1/2 inch over total length.
3.3	CLEANING AND PROTECTION
A.	Protect structural glass flooring from damage during construction until date of Substantial Completion. Do not apply markers to glass surface. Remove nonpermanent labels, and clean surfaces. Clean glass on both surfaces.
B.	Remove and replace glass that is broken, chipped, cracked, or abraded or that is damaged from during the construction period.
