Empire State Building

Empire State Building








The Empire State Building is a 102-story skyscraper located 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 September 11 attacks in 2001, the Empire State Building was again the tallest building in New York (although it was no longer the tallest in the world). The Empire State Building was once again demoted to second tallest building in New York on April 30, 2012, when the new One World Trade Center reached a greater height. The Empire State Building is currently the third tallest completed skyscraper in the United States (after theWillis Tower and Trump International Hotel and Tower, both in Chicago), and the 15th tallest in the world (The tallest now is Burj Khalifa, located in Dubai). It is also the fourth-tallest freestanding structure in the Americas.
The Empire State Building is generally thought of as an American cultural icon. It is designed in the distinctive Art Deco style and has been named as one of the Seven Wonders of the Modern World by the American Society of Civil Engineers. 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 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.

History

The site of the Empire State Building was first developed as the John Thompson Farm in the late 18th century.[17] At the time, a stream ran across the site, emptying into Sunfish Pond, located a block away. Beginning in the late 19th century the block was occupied by the Waldorf-Astoria Hotel, frequented by The Four Hundred, the social elite of New York.



[edit]Design and construction

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.[citation needed] 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.[21][22][23]
Excavation of the site began on January 22, 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.[24] 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 project was completed ahead of schedule and under budget. Instead of taking 18 months as anticipated, the construction took just under fifteen. Due to reduced costs during the Depression, the final costs totaled only $24.7 million (372.8 million 2012 dollars) instead of the estimated $43 million. 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
