San Francisco's Leaning Tower Keeps on Tilting Over

The video discusses a building that has been tilting at a rate of 3 inches per year. A $100 million project to stop the tilt was abandoned in 2021 as it proved ineffective. The building, which opened in 2009, initially saw high apartment sales, but prices plummeted due to the tilting and sinking issues. Currently, the building's tilt has reached 26 inches, and if it continues, essential systems like elevators and plumbing may fail. An engineer suggests attaching 18 steel piles to bedrock to stabilize the structure.
