Empire State Building

The Empire State Building is a 102-story landmark skyscraper and American cultural icon in New York City at the intersection of Fifth Avenue and West 34th Street. It has a roof height of 1,250 feet (381 meters), and with its antenna spire included, it stands a total of 1,454 ft (443.2 m) high. Its name is derived from the nickname for New York, the Empire State. It stood as the world's tallest building for 40 years, from its completion in 1931 until construction of the World Trade Center's North Tower was completed in 1972. Following the destruction of the World Trade Center in 2001, the Empire State Building reclaimed the position of tallest building in New York (although it was no longer the tallest in the world). Once the new One World Trade Center is completed, it will once again be demoted to second tallest building in New York.

The Empire State Building is designed in the distinctive Art Deco style, and has been named by the American Society of Civil Engineers as one of the Seven Wonders of the Modern World. The building and its street floor interior are designated landmarks of the New York City Landmarks Preservation Commission, and confirmed by the New York City Board of Estimate. It was designated as a National Historic Landmark in 1986. In 2007, it was ranked number one on the List of America's Favorite Architecture according to the AIA. The building is owned and managed by W&H Properties. The Empire State Building is currently the third tallest skyscraper in the United States (after the Willis Tower and Trump International Hotel and Tower, both in Chicago), and the 15th tallest in the world. It is also the fourth-tallest freestanding structure in the Americas. The Empire State Building is currently undergoing a $550 million renovation, with $120 million spent in an effort to transform the building into a more energy efficient and eco-friendly structure. Receiving a gold Leadership in Energy and Environmental Design (LEED) rating in September 2011, the Empire State Building is the tallest LEED certified building in the United States.

The Empire State Building was designed by William F. Lamb from the architectural firm Shreve, Lamb and Harmon, which produced the building drawings in just two weeks, using its earlier designs for the Reynolds Building in Winston-Salem, North Carolina, and the Carew Tower in Cincinnati, Ohio (designed by the architectural firm W.W. Ahlschlager & Associates) as a basis. Every year the staff of the Empire State Building sends a Father's Day card to the staff at the Reynolds Building in Winston-Salem to pay homage to its role as predecessor to the Empire State Building. The building was designed from the top down. The general contractors were The Starrett Brothers and Eken, and the project was financed primarily by John J. Raskob and Pierre S. du Pont. The construction company was chaired by Alfred E. Smith, a former Governor of New York and James Farley's General Builders Supply Corporation supplied the building materials. John W. Bowser was project construction superintendent.

Excavation of the site began on January 21, 1930, and construction on the building itself started symbolically on March 17—St. Patrick's Day—per Al Smith's influence as Empire State, Inc. president. The project involved 3,400 workers, mostly immigrants from Europe, along with hundreds of Mohawk iron workers, many from the Kahnawake reserve near Montreal. According to official accounts, five workers died during the construction. Governor Smith's grandchildren cut the ribbon on May 1, 1931. Lewis Wickes Hine's photography of the construction provides not only invaluable documentation of the construction, but also a glimpse into common day life of workers in that era.

The construction was part of an intense competition in New York for the title of "world's tallest building". Two other projects fighting for the title, 40 Wall Street and the Chrysler Building, were still under construction when work began on the Empire State Building. Each held the title for less than a year, as the Empire State Building surpassed them upon its completion, just 410 days after construction commenced. The building was officially opened on May 1, 1931 in dramatic fashion, when United States President Herbert Hoover turned on the building's lights with the push of a button from Washington, D.C. Coincidentally, the first use of tower lights atop the Empire State Building, the following year, was for the purpose of signaling the victory of Franklin D. Roosevelt over Hoover in the presidential election of November 1932.
