Re: San Francisco high-rise sinking, tilting

^ Yeah, thanks for that clarity. I've been thinking more about this and I think it really comes down to: if there is a major earthquake, this building is toast.

If it is and does come down, it will probably damage quite a few buildings around it, too.

Re: San Francisco high-rise sinking, tilting

Even if the city deemed the Building has a very dangerous hazard I bet the developer could auction off the condos for the right price --I bet people would still buy those condos just to live in San Fran. Hazard or not they would risk their life.

Maybe they would, but the hazard of a building that size collapsing is not limited to those who choose to live inside it:

Right, the building really should be vacated and imploded in a controlled manner before it comes down on its own, though I don't know how feasible it is with TransBay next door. Money is money, it comes and goes, but people are gone forever when they are killed.

This building was a colossal mistake, but let's not make it a deadly mistake.

How is the city Inspectors at this point not recommending this?
The city, taxpayers, insurance company, developers, consultants better start digging deep into their pockets at this point.

Itís doesnt take a building structural engineer to say this building is toast

Is there any possible way to salvage the foundation and connect it to bedrock as is?

Re: San Francisco high-rise sinking, tilting

i think it's less likely to totally fail anytime soon.

the tower is probably closer to a leaning tombstone (for now).

Well, yes, it does. We can't make that definitive "toast" assessment on our own, only offer conjecture. Buildings/structures are surprisingly resilient and are designed with redundancies to account for miscalculations, oversight or failure of members. A structural engineer can assess exactly what members are weakened and to what degree, then offer a verdict.

Yes, as has been discussed here, there is a method to underpin it, but it will pretty much cost as much as building a new tower and doesn't undo damage that may not be apparent yet (like to the curtain wall assembly).

Re: San Francisco high-rise sinking, tilting

On Saturday, a drone being used to inspect the building lost its signal and crashed onto the street below. On Monday, someone will rappel down the side of the building and tape the crack. I'm thinking, with the lean, the carriages typically used for window-washing may not work.

Re: San Francisco high-rise sinking, tilting

scary thought; can/will the lean accelerate?

Re: San Francisco high-rise sinking, tilting

Here is a link to the video of the drone crashing.

https://sanfrancisco.cbslocal.com/20...lennium-tower/

The window washing system is apparently broken, thus the rappeling.

The reporter is in error. The leans is 14 inches, not two.

According to CurbedSF, the tilting of the building in the first half of 2017 was at a rate of 2.5 inches over that six month period. That brought the tilt to 14 inches, the numbers seem not to have been updated since. One can reasonably assume that if it had stopped sinking and tilting, it would be headline news in the San Francisco Chronicle.

The plaintiff's lawyers claimed in the summer of 2017 that the building could tilt an additional 8-10 inches over the next two years (from June 2017).
