The new, larger checkpoints feature clear-span designs that maximize the amount of usable area. The column-free spaces improve circulation, alleviate congestion and support long-term growth by creating room for future increases in screening capacity and throughput. Extending the finishes from other areas of the terminal, wood-clad beams, a travertine-stone feature wall and patterned terrazzo enhance the ambiance and blend the aesthetic from the atrium to the concourse. Full-height glass walls provide exterior views and bring abundant daylight into the checkpoints. Using occupancy sensors, time clocks and daylight sensors, the design helps reduce the use of artificial lighting when natural light is sufficient.
