A newly built high-rise residential tower in San Francisco that's home to famed 49ers' quarterback Joe Montana and Giants' outfielder Hunter Pence is slowly sinking and shifting, and may ignite a court battle between residents and the city.
The 58-story Millennium Tower, located at 301 Mission Street just south of the city's financial district, was completed in 2008 and has sunk 16 inches and shifted 2 inches to the northwest since opening, according to a report issued by an independent consultant obtained by KTVU-TV.
The owners of the $350 million building told KTVU the construction next door of the Transbay Transit Center, a $4.5 billion project to serve as a hub of mass transit, has caused the ground movements.
P.J. Johnston, spokesman for Millennium Partners, which built the tower, told KTVU in a written statement that the transit center has been a negative impact on the luxury high-rise.

They mean the 57-story Millennium Tower.
“perhaps the anchors/pilings are not always sufficient to support the entire weight of the building”
Then that would be a failure of the engineers. I’m no engineer or architect, but it’s just plain common sense that you anchor these kinds of buildings to bedrock with sufficient structural support so that the weight of the building is transferred to the bedrock and not the intervening material. Anything less is courting disaster.
Great. Now the whole building will be full of slant-eyes.
Ideally, but sometimes not. In theory, depending on the ground, deep enough pilings should provide enough restive force for the weight of the building. Effectively the foundation "floats". Apparently calculations were off on the ground around this building and this one is "sinking".
I wonder who the engineers were. Chinese?
I guess no one paid attention to the the Ocean Tower at South Padre.

Maybe Mexican, who knows?
It certainly is- from at least one direction.
The $350M builder/owner could take the Larry Silverstein way out ... I’m sure there are a few million willing jihadi’s to call upon for a collision, then make the collapse happen.
You pond the pilings down until you hit bed rock.
Stand an ISIS suicide bomber on the side of the building that’s offset from level and blow him up. See if that levels the building.
Suppose the bedrock is 100 feet down. It does not seem possible that a skyscraper could be built on 100 foot long legs, no matter how thick they were, without any cross-bracing. So the fill does have something to do with supporting the building.
According to some answers from engineers on Quora, foundations of skyscrapers do not always go to bedrock.
One of the piers of the Brooklyn Bridge does not go all the way to bedrock and yet it has stood for over 133 years.
Go see a pile-driver in action.
Pier 66, in Ft. Lauderdale did the same thing 70s!
I believe they used hundreds of tons pressurized grout to stabilize.
