With the greatest of ease, an Empire State Building construction worker nonchalantly breezes by at a dizzying height above New York City. Building the renowned Art Deco skyscraper took a workforce of 3,500 men a total of seven million hours, during which they constructed an astounding storey-a-day. In April of 1931, they completed the building nearly two months ahead of schedule and $5 million under budget. A spectacular engineering achievement, the Empire State Building was named one of the Seven Wonders of the Modern World by the American Society of Civil Engineers.
