In 1930, a major construction project was started on the island of Manhattan in New York City. It was completed in 1 year and 45 days, and finished ahead of schedule. The reported height of the building to its tip is usually given as 1,250 ft (not including the lightning rod). It took 57,000 tons of steel to construct the steel skeleton. The building has 6,500 windows, more than 100 floors, and at peak times, as many as 3,400 workers at one time. The total cost of this iconic building-the Empire State Building, if you haven't already guessed-was approximately $24 million.
