Debunking the Manhattan skyscraper bedrock myth

Economist Jason Barr and his colleagues measured the bedrock depth in Manhattan and correlated it with building height. In doing so, they busted the long-held belief that there were no skyscrapers between Midtown and the Financial District because of insufficient bedrock.

What the economists found was that some of the tallest buildings of their day were built around City Hall, where the bedrock reaches its deepest point in the city, about 45 meters down, between there and Canal Street, at which point the bedrock begins to rise again toward the middle of the island. Indeed, Joseph Pullitzer built his record-setting New York World Building, a 349-foot colossus, at 99 Park Row, near the nadir, as did Frank Woolworth a decade later.
