b'NTCA FIVE-STAR FEATURE (continued) On the exterior, 12 x 12, 12 x 24 and 24 x 24 porcelain tile covered over 8,000 sq. ft. of balconies and decks on multiple levels, some with individual adjoining guestroom balconies or a common gathering balcony. Each location cre-ated a different issue of how to slope tile to drains without creating out-of-tolerance lippage. Plus, the rooftop pool deck was in direct sunlight and scheduled for a summer install, requiring crews to work in cool morning hours, and tent the work areas in the afternoons. They also had to keep materials cool to maintain a reasonable pot life in the heat. The 100,000 sq.ft. project required planning, finesse and superior craftsmanship over the 47-month timeline.

Exterior was a pedestal system engineered by Buzon with its screwjack pedestal system . The marble veining on the porcelain wall panels was designed to align through four different panel varieties. They were installed per TCNA W 244-19, via scissor lifts and rolling scaffolds 25 feet high. The illusion of continu-ous veining was aided by perfectly mitered tile corners, all fabricated onsite. Absolute precision was required for reception desk veining to come together at three differ-ent angles to form a monolithic cubic appearance.The overall project installed 8,000 sq. ft. on the interior and 10,000 sq. ft. at the exterior200 9 x 5 porcelain panels at the interior corridor walls and reception desk.382020|TECH'
