SF Millennium Tower Is Unsalvageable, Will Have To Come Down (2023 Update)

Didn't someone say the building was initially designed as a lighter steel building and later changed to heavier concrete with no change to the foundation? It may well be T&R was not involved in the "upgrade".

Architects aren't the people who validate foundation designs that's an engineering firm's job, they're not experts on rock and dirt!

Well, that's the problem. Should have been designed and fixed by engineers.

"The Millennium Tower sits on a 10-foot-thick concrete mat foundation, held in place by 950 reinforced concrete piles driven up to 90 feet deep. Under the retrofit plan, the 52 new piles will extend into bedrock beneath the soils and will be structurally connected to the existing foundation by an extension of the concrete mat. That anchoring connection will transfer a portion of the tower's weight to bedrock."

The fix still does not address the obesity problem. The middle part is overweighted.

$2 million condos but you can only have balsa wood furniture.

Again, there were women involved. Original Cost to Build to Bedrock for Tower Like Millennium Put at Just $4 Million

The water intrusion means the rebar in their extensively cracked/fractured mat foundation is corroding, if they used metal that is. That's a potentially ticking time bomb leading to catastrophe.

Women are often involved in life. Sad that you don't like them.

The boomers made a pact with the devil to be 40 forever, other kinds of

40-year-olds are aware of this.

I say my good man I shall agree to remove myself from your well-manicured lawn/property but I do demand you cease these scurrilous accusations at once, or I shall have no choice but to compose a disparaging rejoinder regarding the provenance of your mother!

You do not know a goddamned thing about my mother, putz! Just like you don't know a f****ng thing about "boomers".

Your mother made a pact with the devil to infest the world with puerile shit.

Friction pilings don't go to bedrock.

Hey DecayedBrainMatter, you have a mother? You could have fooled me...

From your reference: "To calculate the capacity of a friction pile one has to multiply the pile surface area to the safe friction force developed per unit area.

The skin friction to be developed at a pile surface should be evaluated sincerely and a reasonable factor of safety should be considered."

"Sincerely" IS NOT an engineering term, at least in my five decades in practice. Maybe it is something that has been introduced by the Woke "engineers"

Tom S. is remarkably easy to fool. Even the most implausible Donald Trump lie fools him. You can't get much more gullible than that.

They might have meant carefully. If Tom S. has spent fifty years practising to become an engineer, he should have noticed that not every engineer is all that good at expressing themselves, but then again Tom S isn't all that good at noticing things he doesn't want to see.

If Tom S had actually mastered engineering, he might have noticed that a frictional force has a static component and component that is proportional to the speed of movement. The piles under a building are never entirely static - ground temperature is always changing, and at different rates at different places - so there is always a little movement going on.

Hey SNIPPERMAN, you ARE NOT an engineer and I am. I have NEVER encountered the word "sincerely" as related to engineering practices. Period. For you to say otherwise just indicates the dolt you are.
