  • Millennium Tower, a skyscraper in San Francisco, is sinking and leaning.
  • A recent segment on “60 Minutes” showed staggering footage of the cracks spreading in the building’s basement.
  • Residents of Millennium Tower are fleeing the building and selling their multimillion-dollar condos at a loss.

The situation over at Millennium Tower, a 58-story skyscraper in San Francisco that is sinking and leaning, is likely to get worse before it gets better.

Earlier this month, “60 Minutes” aired a segment on the troubled tower that showed huge cracks running across the basement of Millennium Tower.

“There’s enough of them, a spiderweb of cracks, that you have be concerned about what’s going on underneath,” said Jerry Dodson, a resident who lives on the 42 floor, in an interview.

Dodson, an engineer and a lawyer, told “60 Minutes” that structural and geotechnical engineers suggested he make daily rounds of the building’s basement to check on the stress gauges. These devices measure in millimeters the growth of cracks on the columns rising from the foundation.

The cracks are a constant reminder of the building’s slow descent into packed sand and rubble. Millennium Tower has sunk 17 inches and tilted 14 inches since it was completed in 2008.

What caused the residential high-rise to sink depends on who you ask.

The developers of Millennium Tower, Millennium Partners, argue that construction nearby is to blame for any sinking or tilting. They claim builders of the new transportation hub next door pumped too much water from the ground during a construction process known as dewatering.

When the water levels under the Millennium Tower dropped, the sand compressed and caused the building to settle, according to Chris Jeffries, a founding partner of Millennium Partners.
