What a great mnemonic.

The saga of San Francisco's sinking Millennium Tower continues, as the structure's movement has now created a 1-inch gap between the main tower and a 12-story podium, according to reporting by the San Francisco Chronicle.

LOL. You are an optimist.
Not by chance-—they planned it that way. The area used to be a small boat harbor that gradually degenerated into a landfill. The buildings there are on pilings. In the case of this tower the claim is they just got tired of sinking piles and finally convinced themselves they had enough “friction” in the mud. They are nowhere near bedrock. Investment hint: don’t buy into this one.
The Italians had to buttress the foundation as well, because it was getting worse.
It does! 26 inches to the west.
“The Italians just laugh .................”
The work they’ve done to keep it up (but still leaning on purpose) is impressive and some of it is visible at the site. Notice the curvature of the construction, it started leaning during construction.
Though I have to say I was more taken with the Duomo nearby.
Get away Get AWAY!! Crash, Boom.
Duct tape would degrade too quickly in San Fran's salt air. This is clearly a job for zip ties.
It’s kind of a layer cake. Top layer is fill, then a layer of something called “old bay clay” and then a layer of the “Colma formation”. Finally get down to a bedrock formation. The fix, currently under construction is steel micropiles driven to bedrock.
The original design, which is the same for all of the tall buildings in the area was friction piles driven into the Colma formation.

What a great mnemonic.
No but the bay tides do cause erosion under neath some of the buildings
Much of that area is built on fill. When I worked in the area and watched construction of skyscrapers, they often had to stop work when old ships were found in the fill. What was left of the ships was carted off to museums. In the 1800's, creeks and streams went far inland and the bay shore also extended inland. During and after the gold rush days, this watery land was filled with debris from abandoned ships. Up until the 1960's, bay marshland was filled in with garbage and debris until environmental laws put a stop to it. Much of the financial district is built on reclaimed bayshore marshland. There were very few towers south of Mission Street in the 1960's; now there are many dozens of hi-rise towers up to 50 stories.
He supposedly dropped cannonballs off the top of the tower to measure the pull of gravity on different masses...........

My Nephews Parents in Law live in that Apartment (probably the only conservatives in the building) I believe his Father in law is the head of Tenants committee they put together working with Lawyers. They are smart, they are living in Sonoma in what was a Vacation home fixer upper that they jumped up the timeline in getting it fixed and now they spend a majority of their time there and not in a building that might possibly topple over.
According to the article it has also SUNK 18 INCHES.
An entire story will be a basement in the near future?
I am not going into that tower, and probably no where near either.
I was meaning that the Italians would laugh at the San Franciscans and their measly 1 inch lean.........
The Leaning Tower of Frisco.
San Francisco: It’s not JUST a literal sh*thole, its also unstable and off-balance. Sad to see what has happened to that once beautiful city.
When it falls, the human feces will soften the blow...
