The goal of this project was to increase tourism from international locations by promoting direct flights with new gates big enough for wide-body aircraft, including one for the super-jumbo, double-deck A380 aircraft. This called for improvements to Terminal 3, expanding international gates from seven to fourteen, and constructing an underground tunnel connecting the D Gates directly to the U.S. Customs and Border Protection (CBP) arrival facility. Other improvements included a self-boarding system, new flight information display system, charging stations, and expansion to the seating / hold area.

At the D Gates connection point, a three-story building was constructed with structural concrete walls and composite concrete slab on decks. The tunnel was constructed with structural reinforced concrete and utilized a single-sourced waterproofing system that wrapped the entire concrete structure to ensure groundwater could not migrate into the tunnel. Martin-Harris self-performed the structural concrete.

The interior of the tunnel includes a 100’+ escalator; two 2-stop elevators; four moving walkways (180’ long); ceramic and glass wall tiling; Terrazzo flooring; stainless steel cladding; curved metal wall panels with custom, curved LED light fixtures; custom wallpaper screen printed with vintage photos; backlit advertising signage; and a smoke control system with 4 fire wall curtains. 

This project was unique for several reasons; one of those being that it took place on the tarmac. Another was the immense amount of planning and coordination required to keep the power shutdowns from affecting Airport Operations in the D Gates. Work was scheduled off-hours, re-routed, and temporary power was brought in to ensure operations never lost power.

Martin-Harris also assisted with numerous smaller projects at the same time. These included upgrading power to the Jet Bridges to handle the new planes, assisting with the installation of the Vanderlande Baggage Handling System in Terminal 3, and various upgrades and repairs.

This project is the recipient of the ENR Southwest Best Regional Project and the NAIOP Southern Nevada Spotlight Merit Award in the Renovation category.
