  1. “Mindfulness zone”? So Californian!

  2. Why complete it? What’s the reason for it?
    3
  3. The progress of the tilting has been arrested.
    3
  4. The tilt is only one quarter of one degree. Elevators and plumbing both work.

  5. It is an ordinary German name, like Frankfurter or Oppenheimer.

  6. He is just using the USD as a standard for comparison.

  7. The SF Chronicle reported on 22 June 2023 that the 18 supplemental piles were installed and fully loaded, and that the progress of leaning to the west had been arrested.

  8. That photo was in the parking garage, which is not part of the tower. It is a separate problem.

  9. New York City has a leaning building also. It can happen anywhere. In London, the tower containing Big Ben is leaning.
    2
  10. This is an international site. Units are arbitrary and trivial. Deal with it.
    2
  11. The progress of the tilting has been arrested as of late June 2023, as was reported in this thread a short time ago.

  12. Hamburger did not design this building. He is the remediation engineer.

  13. This is a concrete frame structure. It won’t be straightened by pulling on the frame, it will be straightened by supporting the foundation mat on the low side, then letting settlement of the high side bring the building back toward plumb. The tilt is only about one quarter of a degree. That is not enough to impose damaging stress on the frame.

  14. At sufficiently high altitude, the air is cleaner, it is quieter, and there are no insects.

  15. They showed both the Sears and Hancock buildings. What is your point?
    1
  16. A meter is about 39 inches.
    1
  17. Sure. Why wouldn’t they? The tilt is only a quarter of one degree.
    1
  18. A ball set on the floor will roll to the low side.

  19. yes

  20. Mr. Hamburger was not involved in the design and construction of this building. He is the remediation engineer.
    1
  21.  @johnstuartsmith — You revised it. That’s fair.
    1
  22. He did what he was hired to do. He stabilized the building.
    1
  23. So? Everybody knows that. The plan was discussed at length by all parties before he proceeded to implement it.
    1
  24. He is the engineer who stopped the progress of the lean.

  25. Wrong. The displacement at the top corresponds to a tilt of about a quarter of a degree. That has no effect on the plumbing.
    1
  26. Nothing. It is a UK-based site with an international audience. They may use any units they please. If anything is wrong, it is that some people in the US don’t seem to understand that both US Customary units and Metric units are legal in the United States, so they ought to be able to understand either and convert when necessary.
    1
  27. It is doing both. The west side was sinking more than the east side, which is why it tilted.
    1
  28. What does a man’s name have to do with it. “Hamburger” is a German name meaning “a person from Hamburg.” We once had a US Supreme Court justice named “Frankfurter.” Nobody made fun of him for it. The scientific head of the Manhattan Project was named “Oppenheimer,” a name of the same form. Would you make fun of him for his name? Suppose somebody named a sandwich for the city of Oppenheim? How would that matter to Oppenheimer’s reputation?
    1
  29. Why not? It’s like Frankfurter (a former justice of the US Supreme Court) or Oppenheimer (the physicist who was scientific director of the Manhattan Project). It is just a German surname for someone from a particular town.

  30. The latest report I have read (SF Chronicle 22 June 2023) states that the progress of the leaning has been arrested by the remedial work. Hamburger did not cause this problem, he is the person fixing it.

  31. Everybody is wondering why the foundation wasn’t designed to reach bedrock in the first place. Naturally, no one wants to claim responsibility for that bonehead mistake. The first phase of the “fix” has been installed and it does what it was supposed to do — arrest the progress of the lean to the west.
    1
  32. The problems with this building are not typical.
    1
  33. The building is privately owned. Of course the owners want to fix and maintain it.
    1
  34. As of late June 2023, the 18 new piles have been placed and fully loaded, and the progress of the leaning has been arrested.
    1
  35. The expansion of the canal is the problem. The original locks are sized for sustainable use.
    1
  36. It isn’t about to fall over, but the market for units in the building has definitely been hurt by the inconvenience of the problem.
    1
  37. For large buildings, architects rely on structural engineers to make it work. No doubt there are engineers who specialize in foundations. The question is, why was the foundation underdesigned?
    1
  38. This is a British site with an international audience. Of course they will use Metric units. Conversion to US units is trivial. If you have the means to access YouTube channels, you have the means to access a free conversion tool. Look into it. You look foolish demanding something from someone who owes you nothing.

  39. The Home Insurance building was considered the first. It is gone.
    1
  40. The maximum offset at the top of the tower was about 2.5 feet. That corresponds to a tilt of only about one quarter of one degree of arc.
    1
  41. I wouldn't call it super tall. It is comparable to others in the area.
    1
  42. There was a settlement for the decreased value of the property.
    1
  43. This is a European site.
    1
  44. Librarians call it the “European War.” If you knew what they meant, then they communicated their meaning. They may use whatever style of name they please.
    1
  45. Hamburger’s proposed fix has done what it was intended to do.
    1
  46. It isn’t a joke name. It is a German name which no doubt is much older than the sandwich. We once had a distinguished member of the US Supreme Court named Frankfurter. I don’t remember anyone making fun of his name. I guess that’s a sign of the decline of civilization in the United States.

  47. I think a modest earthquake will help bring it into plumb, now that the west side is supported.
    1
  48. The whole building is tilted. There is not just one tilted side. But you have to be looking in a north-south direction because it is leaning west.
    1
  49. The root cause is that the original foundation has no pilings reaching bedrock. The soil conditions at that site would not support the building as designed. Blaming the neighboring project was just an attempt to distract from the design defect, in my opinion. According to a recent report, the 18 additional pilings have reached bedrock. Since loading the new pilings, the lean has been arrested and reduced by one inch.
    1
  50. That was a magnitude 7 ‘quake. Not the big one. We call it the “pretty big one.”
    1
  51. Hamburger did not create this problem. He was hired to fix it, and it seems he has.
    1
  52. This is a British channel.
    1
  53. In the USA, we use whatever units suit the situation. We are bimetral. Metric and US units are equivalent. It doesn’t matter which a presenter uses in his video. This one is presented by a publisher with an international audience, so naturally uses Metric values.
    1
  54. Hamburger did not design this building. He is the engineer who is fixing it.
    1
  55. It would not be easy and it would be hugely expensive.
    1
  56. Don’t leave out the smash and grab thieves.
    1
  57. The fix using 18 new piles on the west has done what it was supposed to do. It has arrested the progress of tilting toward the west.
    1
  58. As of late June 2023, the 18 additional piles have been placed in bedrock, have been fully loaded at one million lbs each, and the progress of the leaning to the west has been arrested.
    1
  59. His reputation notwithstanding, his solution has worked, so far.

  60. I was in the Bay Area for that. The structures which suffered major damage had specific weaknesses that made them vulnerable. Modern high-rise buildings rode it out fairly well. A magnitude 7 earthquake is significant, but does not cause general disaster, only localized damage.
    1
  61. The city was partly responsible for the problem.
    1
  62. In a condominium, the unit owners generally do own the land as tenants-in-common.
    1
  63. The conversion is grade school arithmetic. You can manage it.
    1
  64. That layer was excavated on the site of the Millennium Tower. I expect that would be done routinely.
    1
  65. The 18 piles have arrested the sinking on the west side, so further settlement on the east side will tend to straighten the building.
    1
  66. Hamburger’s plan has arrested the progress of the leaning to the west. That is what he was hired to do. At this point, he is looking good. Remember, he did not create this problem.

  67. “Always”? Where do you get that? This happens to be a site based in the UK. If you don’t like it, find another.

  68.  @4vinylsound — As I said, listen to something else if this doesn’t suit you.
    1
  69. For a building that height, the lean is only a quarter of one degree.
    1
  70.  @icarusamerica3436 It’s still a standard, but sometimes things go wrong. In this case, the building was put up plumb, level, and square, but then started to lean because of an inadequate foundation. The builders putting up the superstructure can’t be blamed for this. It’s on the foundation engineers, mainly.

  71. Bauernkind 85 — These projects won’t affect General Motors.

  72. That’s a lame reason to watch or not watch a video. This site has an international audience, so it is expected that they would favor Metric units. They are based in Britain, not North America. Units are arbitrary and conversion of units is trivial. I am interested in the substance of a presentation, not insignificant details of notation.

  73. Hamburger did not create this problem. He was hired to fix it and he has.

  74. Otis manufactures in S. Carolina as well as China. They sell products around the world and have installed a few thousand elevators in China, so it is not surprising that they would have a plant in China.

  75. His solution worked.
    1
  76. This site has an international audience and is based in Britain. Their content is better than most of the other sites which have discussed this building.

  77. The company that did the geotechnical work has been acquired by another company.
