The 58-story Millennium Tower cost an estimated $350 million to build in 2008, but the cost to fix the sinking and tilting skyscraper may climb even higher, reaching even to $500 million.
San Francisco Chronicles Mattier and Rosswho first broke the story of the Millennium Towers meandering foundations in 2016now report that a potential engineering fix for the building involves securing only half of the structure to bedrock with hundreds of long micropiles in the foundation and then letting the other side continue to sink until the building straightens itself.
After the structure is level again, further piles will attach the entire building base to bedrock, and all will be righted in the world. The process could take as long as five yearsand come with a hefty price tag.
Pennsylvania-based construction company Nicholson explains that micropiles are:
High-performance, high-capacity drilled deep foundation elements typically between 512 inches in diameter that can extend to depths of 200 feet and achieve working loads of over 200 tons. Micropiles are comprised of high-strength steel casing, rebar and grout.
[...] Micropiles are generally used when there are difficult ground conditions, such as natural or man-made obstructions, sensitive ground with adjacent structures, limited access/low headroom and/or karstic geology. They are commonly used to replace deteriorating foundation systems [...] or reinforcement including embankment, slope and landslide stabilization.
Mattier and Ross go on to report that some of the buildings well-heeled inhabitants arent fond of this fix; there are other competing proposals for how to get the tower and its ritzy business back on an even keel.

And curry favor at the same time. Screw what the government regulators say. The experts are full of it. The repubes will gladly trust and sign checks over to their reincarnated republican "god-emperor" Dirty Donny" himself.
