Imagine 3 inches ruining a multi-hundred million dollar development.
This high-rise apartment building in Lower Manhattan, called 1 Seaport, sits abandoned and unfinished.
What happened?
In short, the building is leaning about 3 inches at the top, and up to 10 inches on some floors depending on when you measure.
All skyscrapers in lower Manhattan are built on pilings driven into the bedrock.
But not 1 Seaport.
Part of the lot, which the developer purchased as a parking lot for $64 million in 2013, was originally under the East River.
Even as far back as the times of New Amsterdam, inhabitants of the city used infill to expand the island. Weāve filled the riverbeds with sand, dirt, and stone to make new lots on the rivers.
The bedrock foundation for most skyscrapers sits 50 feet below the surface; but the bedrock at this site is about 150 feet below the ground.
To build 1 Seaport into a 60-story highrise with 80 luxury condos, most of which would sell for several million dollars, the developers used a rare foundation construction method that involved injecting concrete into the ground to make it more solid.
To date, the partially-constructed site sits abandoned, and has since been sold off for pennies on the dollar.
The building likely canāt be inhabited without some very expensive fixes (if it can be fixed at all).
12 years after the original purchase of the lot for development, weāre as far as ever from people living there.
