Construction of the Empire State Building

The Empire State Building was a city in the middle of a city. Inside was worker housing, cafes, and even its own postal system. Not only that, but it was a masterpiece in money-making. The method of construction was also revolutionary – the prefabricated beams could be assembled in record time, with over four floors built every week! With three onsite restaurants, the 3000 workers were kept fed and energized – so much so that the entire building was completed (and under budget) within six months.
