SF's Millennium Tower fix will not resume as planned. Report shows work was causing further sinking.

After abruptly tilting another inch over just a few weeks during construction in June and July, a temporary stop was put on all work on Aug. 23.

Principal engineer on the project, Ronald Hamburger of Simpson Gumpertz and Heger, told SFGATE that the pause was intended for "two to four weeks." But now no restart date is planned after San Francisco officials at the Department of Building Inspection asked the tower's management not to resume construction.


The sudden drop of an inch on the Fremont Street side was observed after crews had drilled halfway down to bedrock to install new piles, and translates to 5 inches of lean on the 58th floor. Thirty-nine of the 52 new piles have so far been installed as part of the $100 million “perimeter pile upgrade.”

"That moratorium has been effective in halting the construction-related settlement and tilting," Hamburger told SFGATE on Monday. "We are presently working to develop modified construction methods so that construction can safely proceed, while keeping DBI and their expert review panel informed of our plans."

2. Oh, But They Don't Want To Do That

It would be so costly to have to rebuild.

Better to just use it until the day it comes crashing down and kills a bunch of people.

That's what it took in Floriduh. They did not want to pay the price for what it would have required to make that building safe.

3. Two weeks ago China demolished multiple unfinished buildings

because they were determined to be unstable. They had been left up for seven years.
