    The Building Integrity channel did a very good job of explaining the causes of this towers flawed foundation system. While the construction of the transit center may have contributed to the issue, the buildings foundation design is to blame. The bay area is well known for the layers of silt and clay that underlay many areas. Where the tower was built used to be under bay water until filled in. I believe the builders wanted the city of San Fransisco to pick up the 5 million dollar tab for setting pilings all the way to bedrock, so went the cheaper route when the city refused. Now they are spending more than that just in lawyers fees.

      @j. rodman
      My understanding is that the de-watering that occurred for the excavation of the transit center may have accelerated the sinking problem, but was very unlikely to be the cause. I saw a nearby project that used cased pilings being installed after the de-watering and excavation for the transbay center, where an outer steel tube is driven into the ground while the center is being emptied out with a drill system, then the center filled with reinforced concrete. I remember watching this process, and they were pulling a lot of water out with each load of material. I could see the different material being pulled up as they went through the different layers. That bay clay is a sticky gooey mess.

      @Michael Dintcheff not necessarily... as mentioned, water seemed to seep through the walls. So possibly it's just an issue related to corrosion of the reinforcement bars. As corrosion increases the volume of the rebar, internal stresses can lead to the concrete covering starting to crumble. I would definitely check what's going on with the water ingress.

      @Michael Dintcheff accurate, yessir. The more that wall breaks down, the less load it takes, that weight doesn’t go away, just gets transferred to other places, weaker places, places not meant to hold that much, so it becomes a bigger problem literally every minute they’re not doing anything.

  • Scott Kirby
    Scott Kirby Рік тому +174

    one major issue you skipped. the lean was spotted in 2011 before the transit centre even started digging. Also the height and weight of this building (being both tall and concrete, a first of that combo in the area) is far outside of the norm yet they didn't go to the bedrock even when that is common for most towers anyway. so instead it will cost 20-50 times the cost to put a pile to that depth now than during construction.
    I personally expect a it to be written off as the lawyer and repair costs spiral to more than the building is worth.

    The cracking basement/parking walls are freaking me out. The house I grew up in had a full basement that wasn't built properly, so when it rained, water would come down the front wall of the house and seep through the underground wall, flooding the basement. You'd hear these loud, scary creaks and noises.
    It also had a concrete carport that butted up to the front door, and about five years in, the slab sank 12-14 inches. I was so happy the day we moved out!

    My mom used to work in a 23 story building (on the 22nd story). Every time I went up there and looked out the window, it seemed like the building was tilting down. I just chalked it up to my fear of falling or an optical illusion. I mean, the building didn't fall, right? Well, now I really wonder...maybe it was leaning. It was the second oldest 20+ story building in the city and the elevators were constantly stalling...

    Truth is, during the foundation construction they dug open a sub-terrain well-spring. As they pump the well dry the soil will compact. Since it appears to be a massive well, the building is a goner and the city's construction approval is dubious.

      It’s fairly common to use large helical piles in dense soil. This is far from the only building to be built this way - with the vast majority having no issues.
      The real issue here is probably the unexpected level of groundwater that needed to be pumped out and caused significant settling.

    A couple of small not addressed in the video:
    1. The original construction was supposed to be steel, not concrete. The change in materials made it a much heavier building than the foundation was intended to support.
    2. Millennium Tower is built on land that was once part of the bay but was filled in during the mid to late 1800's. This type of land is tricky to build on in areas with earthquakes, even for much smaller structures.

      I wouldn't be nervous in San Fran's TransAmerica building, which is anchored to bedrock and which did not drop a single pane of glass in the Loma Prieta earthquake. I am never nervous in the 100 story Hancock tower, or the Sears (Willis)Tower's 110 stories. High rises have always seemed to me to be a very trustworthy type of building. But I'd be nervous as hell in this building, as well as many other high rises built since the 70s. It appalls me that a 58 story building in San Francisco was not anchored to bedrock, and it seems to me that too many buildings built since 1980, especially, were built to the minimum, with every corner cut the builders could squeeze in, and with no concern as to the long-term viability of the building. What do THEY care- they're not building for long-term ownership, they're building to sell the units as quickly as possible and run with their profits.

    In Brazil, there’s a city that has a large quantity of tilted buildings, due to soil compression and stress on foundations. The city is called Santos, and if you ever look at the pictures (specially if taken from the shoreline) the leaning buildings are quite noticeable, even by walking on the streets you’ll notice how much they sunk. The funny thing is that a lot of people live in those buildings and don’t seem to care that much, some owners try to correct the tilt by leveling the floor using a thin layer of concrete.

    The term piling is used. Actually, the video shows drilled piers being installed. Earlier news articles reported that this same type of foundation system (drilled piers) were used for new construction adjacent to this tower. Moreover, during the installation of the piers for the new construction, the drilled pier contractor was removing more soil from the cased holes then typical. In other words, soil (sandy fill) was caving into the cased holes as the casing was being advanced. This resulted in a loss of ground around the existing drilled piers for the Millennium Tower. Such loss of ground compromised the ability of the existing drilled piers to resist vertical and lateral loads causing tilt.

    Don’t think so, this towering mistake one day will have to come down. Most probably this structure has been built over a former stream which wasn’t accurately mapped and later filled in with dirt. Especially the way the concrete in the basement is affected by corrosion is a definite sign of a much higher water pressure in the vicinity of this corrosion. Such pressure most possibly caused by seepage. In many cases the forces of seepage is much, much higher than what pumps can ever produce.

Especially when ebb and flood tides also play a role in such an environment, the ‘topsoil’ of such an estuary will over time be cleaved by dozens or even hundreds little and bigger stream beds. The existence of such stream beds will imply that as soon as the land is reclaimed, the possibility of seepage through these old stream beds will almost always remain. Especially when they’re not diverted, let’s say, upstream. Or, otherwise said, diverted from the higher elevation to the lower laying surface of the reclaimed land. In that effect, as soon as groundwater accumulates inside the body of soils of the higher elevations, it will seek its way through the soil on a path of lowest resistance. Exactly those old stream beds form the excellent pathway for accumulated excess of groundwater to have its effect on soils which are part of reclaimed lands. This in fact means that such soils need to be researched thoroughly for possible subterranean streams, before these soils are ever considered to carry a load similar to the millennium tower. I humbly think such research either hasn’t been carried out, or, at the very least not thoroughly enough. To put such a structure on a sticky foundation is a rather odd one, especially when one considers the underlying bedrock isn’t that far away. Also, the solution to just adapt just one side of the foundation of this structure is yet another sign that the constructors are just asking for more trouble. San Fransisco definitely got its version of the Pisa tower, that’s for sure.

    When the tower opened in 2009, (1:38 m/s) everything was not fine. The expert panel, commissioned by then mayor, Edwin Lee & his 301 Mission Seismic Safety Committee, concluded that the deformation of the mat foundation occurred before 2009.
    The project's Geotechnical Engineering Firm had issued its second settlement forecast.
    Further, the Transbay Joint Powers Authority installed over a hundred crack monitoring gauges in the basement of the tower BEFORE the City issued the projects Certificate of Final Completion.

      @W. Harrison I agree that engineering via political theorizing is a bad idea. Engineering is a discipline where the cold hard facts should always determine the outcome. But it appears that in this case a well-connected male civil engineer in a private company mis-designed a building and has never owned up to it. It is more typical in such situations that the bad engineering was approved via the influence of an "old boys network" than that a woman (and a feminist, if you are correct) was pressured into approving it. So, do you have evidence for this claim, apart from the general observation that San Francisco has ultra-progressive politics, which I will not dispute?
      Note that I am agreeing with you here on some points, while questioning your premise that "San Francisco has ultra-progressive politics, therefore this particular error must be a product of those politics".

It changed the entire look and feel of that area in downtown San Francisco. But for today, nobody would notice.. it’s surrounded by much taller new towers including the city’s’ tallest. Salesforce Tower. It broke my heart when I heard it was sinking. That was about 7 years ago now. It’s crazy how much the city has allowed it to sink. The elevator shafts are over 1.25 inches from the building. Which makes it illegal under California standard building code requirements. I’m surprised they have red tagged it and taken it down by now. They really must want to save this skyscraper as it was such a huge investment to San Francisco. The destruction would be horrific if this thing came down. The street below, Fremont, is constantly busy. Then there’s the brand new billion dollar Salesforce Bus Terminal with a public park right on top. Children that play at that park. And those who live / work in the neighboring towers. A catastrophe waiting to happen. So sad. I hope they can fix it, and fast!

    There are two other options that may be used. The first one is to to build a L-type support foundation on the side that is sinking. That will cost less than to dig to rock support. The second is to use the building that it is leaning towards to, to connect the two buildings at the highest point possible with a support structure very similar to sky walks, but in this case mainly to keep the tower from tilting any further.

    • Bernd Jendrissek
      Bernd Jendrissek 16 днів тому

      @That one guy The connection only has to resist lateral movement, not vertical movement. It doesn't need to support the weight of the entire building, just the moment of the weight over something like a "center of support". Which, because it's such a tall, skinny tower, isn't all that great (compared to the total weight). (I realize I'm switching between weights and moments here, but in the interest of my not having to write 5 pages to treat this rigorously, please just take this comment as a shorthand for all of that.)

    • frank nilson

      @That one guy I agree with what you are saying. That is why I said that proper calculations must done to cater for the weight of the building, the strength of raw-bar, and concrete. The first suggestion that I placed suggested that the support, similar to a book stand be placed on the outside of the tower where proper drilling, digging can be done easily without trying to work underneath the building. Depending on the weight of the building, the size of the platform could be calculated, i.e. the breadth, length, height, depth and weight and with additional concrete foundation columns at the far end of the book stand, you could achieve your goal. Hopes this makes sense to you.

    • That one guy
      That one guy 11 місяців тому

      @frank nilson but the building isn’t sinking because it’s tilting, it’s tilting because it’s sinking. A connection to another building would have to be able to hold the weight of an entire building sinking into the ground.

    • frank nilson
      frank nilson 11 місяців тому

      @That one guy The first method will work like a book stand that keeps the books in place. If the calculations and concrete and steel support are done properly it will work. The second method is basically the same, as the building next to it is that book stand that is already fixed, and with a proper support as high and strong as possible will keep the tower from tilting. Without pressure on the foundation then in both cases, the ground will not sink as much unless the soil is very acidic which could destroy any rock formations such as dolomite.

      @Bernd Jendrissek Here's what I'm saying;
      After your P trap, the pipe is supposed to slope away, so that water (or debris) can be washed away. Slope it the wrong way and everything stays stuck in the P trap. How much stuff goes down the kitchen sink? Bathroom sink?
      You ever install a kitchen? I have. Let's say you have your 2" or 1.5" pipe sloped the wrong way, behind the sink, running along the wall, until it gets to the main.
      Unless you have access to the wall from the other side, you are pulling off countertops, removing cabinets THEN breaking the drywall to fix the slope, then re-installing it.
      Every try to remove granite? Without breaking it? With the sink cut? Do you know how easy it breaks?

      @frankpinmtl Ok but opening up drywall is nothing compared to having to open up masonry let alone concrete (this is a skyscraper we're talking about). I don't know about San Francisco but in my city large buildings' sewer systems are generally in accessible places, although there may be short sections hidden behind drywall.
      And still, for the flow to reverse, a building's lean would have to exceed the 1:50 gradient that's the lower limit for sewer pipes (and more likely something like 1:20).

      @Bernd Jendrissek So let's say the plumbing is run a certain way, with a slope to allow the natural gravity to flow the water. Tilt a building in the other direction, all of a sudden your water doesn't flow down the pipes, but back up

      Probably should be, it's gonna take a hell of a lot more than one man to stabilize an entire skyscraper

    Im pretty sure the pile depth was based on the soil test and it showed it was safe. however sometimes, you need to dig more LOL

    I spent 6 months in San Francisco over a 7 + 3 year duration + other visits. I can't believe any builder of a skyscraper would not anchor the building supports to the bedrock, given the earthquake issues. All you had to do was read the paper/Guardian or talk to somebody about the ever-present issues associated with building retrofits, seismic stability of particular regions, and building single family homes on the equivalent of "floating pads".
    Because I am a project manager, have read numerous case studies, along with reading the other comments, I am inclined to think that the so called extra time needed to anchor the support of the building was more of an issue than the cost, but perhaps I am mistaken.

      in many cases for smaller buildings, you really don't need it. But the Millenium tower is both in the top 5 tallest buildings and the only really tall building made of concrete (oh, that was a late change, the foundation was already set for a steel frame...no need to recalculate). So this was a damn easy call. Even so many even medium-to-tallish building will go down to the bedrock for extra safety and just to have margin of error.

    Had no idea you can extend foundations on a high rise after built. Very interesting I wonder how the do it.

    Reminds me of an over 2000-year-old story about building a house on sand or rock. They should have anchored to bedrock from day 1

    Remember the building that collapsed in Surfside, Florida? They kept saying it was safe. When someone tells you there's no "immediate danger", that's when you need to start running for the hills.

    Dubai used some inland-origin desert sand to create land reclaimation but changed to sands from the sea because inland-origin sand is unstable. However, it is good how they showed what can be done as having unstable sand encourages the reclaimed to be used for something that is not buildings (such as crops, like coconut, etc.). The inland-origin sand is abundant but the places in the sea you might put it are not so much. Heavy railway for inland-origin desert sand, one day could restore permafrost eroded land _(but it is only part of the "ingredients", such as rock)._

    Okay cool. I also noticed the garage walls are crumbling because of groundwater.
