This $290-million, 430,000-sq-ft addition more than doubled the casino and resort’s convention space.

The design-build project comprises four buildings on approximately 32 acres: a three-story, 250,000-sq-ft multipurpose building; a high-bay, 120,000-sq-ft advanced test facility; a one-story, 3,000-sq-ft visitor center; and a 2,500-sq-ft central utility plant.

Surrounded by high desert land and rolling hills within the Navajo Nation, Kayenta II Solar marks the second phase of a tribally developed, owned and operated solar facility, the first of its kind in the U.S.

This project was the third and final phase of the 1.9-million-sq-ft renovation and expansion of the aging airport terminal.

The project team faces big challenges in merging older structural systems with plans that call for newer, more open spaces.

The entertainment portion of the downtown Las Vegas resort will open this fall, with the hotel tower to follow by the end of the year.
