This public works project at McCarran International Airport in Las Vegas, featuring a central utility plant covering 100,000 sq ft, is constructed of cast-in-place concrete and structural steel, with tilt-up exterior walls. The plant has a below-grade water basin that holds approximately 250,000 gallons of water feeding six concrete cooling towers with a dedicated boiler room and chiller room, as well as an exterior power yard with backup generators. The central utility plant is located approximately 1,000 ft away from the airport’s massive new Terminal 3 project and will supply chilled and heated water for the terminal’s mechanical system through an underground tunnel.
