Sky Lobby Diagrid Ceiling
The Leffler Group was tasked with designing and providing a BIM model of the hotel lobby ceiling that fullfills the Architect's intent of imitating the steel diagrid canopy, creating a continuous barrel vault effect.
The model was used to determine the final shapes and locations of custom GFRG and aluminum extrusions, along with framing and drywall.
Exact wire hanger locations were coordinated with MEP models to ensure proper support.

Sub-AGTS CFS Framing
The Leffler Group designed a Cold-formed steel support system for equipment items spanning under the Above Ground Transit System platform (the train platform above). The high cyclic vibrations of the platform do not allow any permanent equipment anchorage to its underside.
The largest span includes 12" deep joists 25ft-45ft clear under the largest portion of the platform.

Escalator Framing
The Leffler Group designed artwork support for walls in the 5 story tall continuous escalator atrium which extends from the transit arrival platform to level 5 of the main terminal.
The custom artwork weighs upwards of 5,000 lbs mounted to the walls and ceilings.
