Measuring 1,250-feet high, the Empire State Building is the best-known skyscraper in the world, and was by far the tallest building in the world for more than 40 years. The building's most astonishing feat however, was the speed in which it rose into the New York City skyline. Construction was completed in only a year and 45 days, without requiring overtime.
Ironworkers set a fervent pace, riveting the 58,000-ton frame together in 23 weeks. Just below them, plumbers laid 51 miles of pipe, electricians installed 17-million ft. of telephone wire and masons finished the exterior in only eight months.
The building was so well engineered that, in 1945, it was easily repaired after a B-25 twin-engine bomber plane crashed into it in the dense fog. The precise choreography of the project revolutionized the tall building construction industry.
Although it has been surpassed as the world's tallest building, the Empire State Building remains the standard against which all other skyscrapers have been judged for the last 65 years. ASCE also designated the Empire State Building as one of its Monuments of the Millennium.
