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


China

Recommended Posts

I've been reading more on this and San Fran only recently allowed skyscrapers and no one seems all that certain about how they'll fair because there's not much data on buildings that big, built on sand (yikes), being hit by earthquakes.

 

How can anyone justify paying over a million for a condo in a sky scraper built on sand in an earthquake zone? Real estate has risks, but that's a great deal more than usual.

There's no doubt in my mind we are pushing the boundaries of what we should or should not be doing in regards to where we live and grow food.  We've gotten away with more than it not being a problem (though hard to ignore communities in middle if nowhere getting hit by wildfires).  I did not know that about SF having skyscraper ban, but not surprised it lifted with land value skyrocketing.  Honestly that sounds more like the easy way out, not the safe one.

With the Millennium Tower, San Francisco got a foretaste of what it means to have a structurally compromised skyscraper. If the city is hit by a severe earthquake, experts fear there could be many more.

 

The area around Millennium Tower is considered among the most hazardous for earthquakes. The United States Geological Survey rates the ground there — layers of mud and clay — as having a very high risk of acting like quicksand during an earthquake, a process known as liquefaction.

Good article on the situation in San Fran in general, worth a click if the topic interests you.

SF taxpayers face steep legal bill over sinking, leaning skyscraper

 

Oct. 3 (UPI) -- San Francisco's Millennium Tower is quickly becoming a boondoggle for city taxpayers, who may have to pay millions more to fix the sinking skyscraper.

 

The residential tower has sunk 18 inches and leans more than a foot to the side since it opened in 2009 -- physical changes the building's owners blame on the Transbay Transit Center across the street.

 

Taxpayer money will pay for Jones Day, an attorney defending the city from claims by the developer and residents that the Transbay Transit Center construction caused the 58-story luxury high-rise to tilt.

 

Nine lawsuits have so far been filed by parties to the case.

 

...

 

In addition to the sinking and leaning, the Millennium Tower also recently showed a crack on one of the 36th floor windows -- which was a mystery until Wednesday.

A report concluded the crack was caused by some exterior impact, not a construction problem. It could take several months to replace the window.

 

The Transbay Transit Center, which has been renamed the Salesforce Transit Center, was closed closed after cracks were discovered in a steel beam. Officials are still trying to determine what caused them.

What's considered a skyscraper? There are 60+ buildings 400+ feet (roughly 35+ stories) tall in SF right now. 

 

And many of them aren't new....

 

 the latest definition is over 40 floors and more than 492 ft according to wiki.

 

it used to refer to much shorter ones
