The Mayor of Chicago (USA) today announced the futuristic designs made by the five finalists competing for the renovation of O'Hare International Airport, including the Spanish architect Santiago Calatrava.
Next to the Valencian creator are the alliances formed by Fentress-EXP-Brook-Garza, Studio ORD, Foster Epstein Moreno and Skidmore, Owings & Merrill, local authorities revealed.
Among the proposals abound the sloping roofs, glass walls and some extravagant features such as hammocks that travelers could use to nap before the flight.
Also the naturalist touches, with the installation of trees, wooden roofs or patches of grass inside the terminal.
The Valencian architect presented a design that he described as "a masterpiece of modern terminal architecture", and which will be exhibited to the public along with the others until January 31 at the airport, on its website and at the Architecture Center of Chicago
The terminal conceived by Calatrava is shaped like a ship's prow with a white wavy roof that protrudes over the runway approaching the terminal.
In a message on his Twitter account, Calatrava said his proposal for this contest, which includes a popular vote, is a "world-class aviation concept" that presents a "dramatically elevated identity" for the Illinois airport.
The interior will be illuminated with skylights, abounding the color white on white that is a feature of his creations.
The Calatrava project is the most extensive, because it not only covers the global terminal of 2.25 million square feet (200,000 square meters), but also adds a business wing with gardens where there is now a parking lot.
The designs are conceptual and the Mayor did not report on the cost of the individual proposals.
The work, which will be the largest project in the 74-year history of O'Hare, will require about eight years and cost about 8,500 million dollars (7,400 million euros).
Chicago Mayor Rahm Emanuel said in a statement that the renovation will point to O'Hare catching up with other airports in the United States, such as Atlanta's Hartfield-Jackson international.
The remodeling of the airport will include the construction of a global terminal, which will go instead of the current number 2 and will be used mostly by United and American airlines.
In this terminal, domestic travelers can connect with international flights without delay and without having to travel to terminal 5, which is currently the base of international operations.
It is also expected that the remodeling will increase by 20% the boarding gates, which will reduce delays and accelerate the displacement of the 78 million passengers that use the airport annually.
