Large crack reportedly forms in window of San Francisco's sinking Millennium Tower

 

A new defect in San Francisco's sinking and tilting Millennium Tower has appeared.

 

A large crack reportedly formed in a window on the 36th Floor of the building on Saturday, according to a resident.

 

NBC Bay Area reports Millennium Tower residents heard a "creaking sound and then a large pop" before the crack appeared at 2:30 a.m. Saturday.

 

Supervisor Aaron Peskin confirms there's a crack in a window and says, "Building management sent an email to all the tenets owners that they thought this crack had to do with the ongoing problems with the building—i.e., the settling, sinking of the building."

 

Peskin says the window system that's part of something called the "curtain wall" is designed to sustain hurricane force winds.

 

"If a window failed entirely it would rain shards of glass hundreds of feet below down onto one of the busiest, most congested parts of the city. The city better take this seriously," Peskin continued.

 

.....

 

Residents learned in 2016 that the 58-story building was sinking, and a flurry of lawsuits from  owners of condos followed, including one from the homeowners association seeking $200 million.

 

Residents paid anywhere from $1.6 million to $10 million for their units.

 

The building has sunk some 17 inches since construction began in 2005 and its tilting about 14 inches.

And why is anyone still living in that thing?

Sounds like building that needs to be razed.

no ****...   

High probability earthquake zone.

Building already unstable, and apparently crumbling. The glass cracking shows that it's already probably out of square or compressing.

 

Sure, i'll move in tomorrow.

It is pretty unbelievable with the amount of capital, underwriting, and plannin involved in a project like this that basic engineering flaws can occur


Eh, the bigger the project the more likely someone in a trade will take a short-cut. Look at the metrorail project here in VA. That's a near 3 billion dollar project and dudes are catching fines and charges for messing with the water to concrete ratio and falsifying documentation around it.

There are definitely a lot more variables on the large projects, no doubt.  Lot more opportunity for short cuts like you said

 

But this strikes me as basic engineering, the very foundation of the structure.  Not sure how that is possible

I hear you. If it's just a mistake, something must not have been caught during submittal review of the shop drawings. I'd hate to be the engineer of record for that mistake or his/her insurance company. 

I'm just guessing but it seems like there is a shear force working on the middle area of that building (it's 58 stories and the window in question is on the 36th floor) caused by the current tilt maybe, pulling against the existing supports.  And if that is the case, it's only going to get worse if the sinking/tilting continues.

You make good points...what if I knock $100 off your monthly condo fees? And, on Tuesdays, you'll get free use of our rooftop pool!

Flawed construction in an earthquake area?  Chileans know how that plays out.

Sometimes flaws are only discovered after things go wrong and earthquakes tend to expose them in rather dramatic fashion.  The millennium tower is showing its flaws early, which should result in the building being vacated until it can be fully repaired or torn down.  The Alto Rio Condo was only 15 stories, and looking at it laying on its side is frightening.  I wouldn’t want to be anywhere near the 58 story millennium in an earthquake.

Has anyone else here actually seen it in person? It won't fall.

 

There is already a retrofit in the works using micro piles to stabilize one side of the building. As the other side sinks it will straighten out. ?

 

The main problem (from what I've heard over the years) was that its allegedly not built on bedrock like some of SFs other bigger buildings. Rather, it was anchored with friction piles that are suppose to be driven deep enough to provide resistance. This is an acceptable practice but as we can see with this building, it does have a failure rate.

Looks like some one is trying to sell their condo on ES. ;)

....

 

 

Hell... San Franciscans know how that plays out   

 

 

(or at least san franciscans like

Paul Newman,

Steve McQueen

William Holden

Faye Dunnaway

Fred Astaire

Robert Wagner

and....

No no no! I blame Obama and all those brown people he let in to the country to do the construction. Geez, next you'll be saying it was rich white guys who caused the financial crisis, when we all know it was treasonous deep state socialists obsessed with sabotaging the Iraq war at all costs.
