Millennium Tower, San Francisco, leaning more than predicted

It apparently settled (1 inch) in three months what was predicted in one year. And earlier predictions had settling the core region, not to one side. According to a report, it's leaning 22 inches (from vertical), ostensibly at the top of the building!

They had better sling some big ropes around it and the adjacent buildings so it doesn't fall over.

If it topples, it'll take other buildings with it. Just image a M6 earthquake or stronger. If they get liquefaction in an earthquake - I wouldn't want to be nearby.

Indeed! That could be catastrophic.

Rune Storesund, UC Berkeley Center for Catastrophic Risk Management, so much said so. It seemed an understatement.

The developers behind the sinking Millennium Tower paid for an independent review of the tower itself before it was built, but not of the site it sits on, according to new testimony at City Hall on Thursday.

The Government Audit and Oversight Committee quizzed Jack Moehle, a professor of structural engineering at UC Berkeley, whom Millennium Partners and its engineer consultants hired to conduct an independent peer review of the building design while it was being entitled.

“The interest was to do an internal review to ensure that the structural system selected was suitable,” Moehle told city lawmakers at Thursday’s hearing. “[So] that if there was a formal peer review for the city later that most questions would be dealt with already.”

Moehle says he inspected the high-rise’s design from top to bottom—but no lower than the bottom. A geotechnical review—i.e., an assessment of the condition of the soil under the building site—wasn’t part of the process, because no one ever hired a geotechnical engineer.

This last part is fundamental to such projects. I don't know if they did or did not hire a geotechnical engineer. That requires different expertise than a structural engineer who looks at the building structure within the building envelop.
