John Jacob Rascob built the Empire State Building because he was competing with other entrepreneurs to construct the tallest skyscraper in the world. His main competitor was Walter Chrysler, who was attempting to build the world's tallest building in New York City at the same time.Know More
The French completion of the Eiffel Tower in 1889, at 984 feet, spurred American architects to outdo each other to construct the world's tallest skyscraper. In 1909, the Metropolitan Life Tower reached 700 feet and 50 stories. In 1913, the Woolworth building reached 792 feet and 57 stories. After the Bank of Manhattan building reached 927 feet and 71 stories in 1929, Walter Chrysler and John Jacob Rascob joined the fray. Each kept the details of the height of his building from the other. In the end, the Chrysler Building topped off at 1,046 feet, while the Empire State Building, at 1,250 feet and 102 stories, became the world's tallest skyscraper, a record it held until 1972, when the World Trade Center was completed. In 2009, when the Burj Khalifa building in Dubai was finished, it became the world's tallest building at 2,722 feet.
To build the Empire State Building, Rascob first bought the old Waldorf-Astoria Hotel, and demolished that building to use the site. In the race to be first and tallest, the Empire State Building was constructed in only one year and 45 days, and its cost was almost $10 million less than its $50 million budget. On the opening day, May 1, 1931, President Herbert Hoover symbolically lit up the Empire State Building from the White House by pushing a button.Learn more about Architecture

The Empire State Building, the Pentagon and the Lincoln Memorial are examples of famous buildings made in part from limestone. Limestone is considered prime building material and used extensively because of its high durability and carvability.Full Answer >
A major advantage of arch bridges is the fact that they are structurally sound for short spans, while a major disadvantage includes the amount of building materials needed to construct an arch bridge, even if it is of short length. Other advantages of arch bridges include the inexpensive costs of building materials such as stone and brick, and the ability to build more arches to span a wider distance.Full Answer >
The key to constructing an earthquake-resistant building is to minimize the forces acting upon it, rather than to maximize the strength of the building itself. Among the methods used to accomplish this are base isolation systems and energy dissipation devices.Full Answer >
