Dome

Concourse with people mover in center; exposed structural elements recalls 19th century glass and iron construction made modern by uniform white paint; United and American both established nationwide hubs at the airport in the 1980s, which continue to operate today. United developed a new $500 million Terminal 1 ("The Terminal of the Future" or "Terminal of Tomorrow") designed by Helmut Jahn and A. Epstein and Sons, with Turner Construction as the construction manager, and Thornton Tomasetti serving as the structural engineer. Jahn described his design as drawing inspiration from the exhibition halls and railway stations of the turn of the twentieth century, with open floor space and lots of natural light. The 850 ft. tunnel connecting Concourse B and C, also designed by Jahn, has become one of O’Hare’s defining features. Jahn worked with artist Michael Hayden and composer William Kraft to design the complex light sculpture called “Sky’s the Limit,” which covers the ceiling of the tunnel and undulates to music, computer controlled. It includes 466 neon tubes and lighted panels. Source: Wikipedia; http://en.wikipedia.org/wiki/Main_Page (accessed 3/30/2014)
