A $100 million fix to stop a San Francisco luxury high-rise from sinking and tilting even more is on hold while engineers try to learn why the building has sunk another inch (2.5 centimeters) during the repair.
Doug Elmets, spokesman for the Millennium Tower, said in a statement that pile installation to beef up the building’s foundation is on hold for two to four weeks as they try to understand why the “increased settlement rate and available means of mitigating this.”
Elmets said the building is safe...
But by 2016, the building had sunk 16 inches (40 centimeters) into the soft soil and landfill of San Francisco’s dense financial district. It was also leaning, creating a 2-inch (5-cm) tilt at the base and a 6-inch (15-cm) lean at the top. Residents sued the developer and designers

Blow it up real good.
Wait for The Big One - if the Yellowstone Caldera doesn’t belch first.

usually a lean is top to base
Working in downtown San Francisco many years ago came across a plaque on the ground marking “the original edge of the San Francisco Bay” it was 6 blocks in from the bay. Grant St was the first street by the bay and it is in the middle of North Beach.
Have everyone in the building move to opposite of the lean. It will balance out.

Nothing in San Francisco is straight.
I seem to remember that a fair amount of San Francisco is on reclaimed land. They should’ve consulted the Dutch, they’re masters at it.

The building has to be on driven piles. It would be interesting to see how the developers spec’d that out.
