If we think that in certain circumstances the ground behaves like a fluid, such as on the banks of rivers, on the seashore or even in land with a high water table during seismic events, (soil liquefaction) a structure that floats to prevent differential subsidence. This solution is typical in medium-sized buildings when we excavate the ground in a proportion equal to the weight of the building. And by mediums I mean the order of twenty levels of height.

Yes, generative design has been present on Revit for about 2 years now, and it has been improving ever since. Check Autodesk Fusion 360, they are already using AI for creating generative designs.

Hey, what's the worst could happen?

Yes, engineering is amazing, and it has been done many times. Depending on the design, you can compensate so it actually floats (steel structure), or compensate at the bottom, like you would in a compensated foundation (concrete structure), so the tide wouldn't affect the bridge. You have many design choices, and again, there are many examples already across the USA.

Think of the bridge as a boat, if the accesses are articulated, the bridge will rise and fall with the tide. The idea is not new in Japan and in Seattle there are floating bridges.

@@pabloviadas7564 A hurricane can mess a boat up pretty bad.

That is exactly what the story said. duuuh

The project has been halted multiple times after the Texas Department of Transportation identified several problems with the foundations, most notably excessive torsion and other stresses during construction. Again these are official reports from the TxDOT.

Today, the structures that have lasted the longest are in the United States.

You're very welcome!

This water is from a new pool constructed in the roof!!!

Discard the theory of water. Water can damage structures, true. But not to the point of collapse. I have reviewed many structures in contact with groundwater laden with sulfates and chemicals. And that has not brought them down. What is appreciated are columns with cracks due to vertical loads. Let's not turn it around, the building was overloaded beyond its design capacity.

@@pabloviadas7564 If the Piles was taking on saltwater for years and it was showing up as water on floor of parking area in and by 3 main columns that was first to come down in video..

Yes of course. Wait for our next video. It's overload damage. We have evidence.

So a heavy AC unit on the roof that disappeared, somehow caused the pool deck on the ground floor to collapse first?

Oh really, like when the HOA called in an engineer to give a report on the structural concerns, and the engineer told them it was bad, so the HOA told the town of Surfside and the Lead Building Instructor who review the report, then came to the HOA meeting a few weeks later and told the HOA that the building was fine and safe and they have nothing to worry about? Sounds like they took all the proper steps, except for being incredibly distrustful of government officials.

Do not tell anybody. But you're right. A real estate company sold a Pent House at 8777 with a pool. I don't know if they built it or were just planning it.

@@817nickmw Look, I check structures in Mexico City where every 18 months there is a significant earthquake. The terrain is very bad, the worst in the world. And believe me, a structure is not verified. We use a laser point cloud scanner and high precision accelerometer registers. And even then nobody does anything.

No it isn't, it's completely wrong.

Sorry. To the next.

Sorry.

Dale una vista a la serie de videos sobre el colapso de la Linea 12, en el Canal de Editorial Viadas, la contraparte en español de Virigina eLearning.

Do not discard it. But there are many concrete structures in contact with water, salt water and black waters. And they have not collapsed. For example, sites foundations where the flattish level is highly contaminated with black water, the concrete becomes severely damaged, but not to the point of collapse. Here it is clear that there is an overload in a precariously structured building.

I doubt that only maintenance may have avoided disaster. It should have been dismantled and restructured. Placing with an additional metallic structure. In all frames. Or more appropriate; Contracy again.

Thanks for the precision. But this does not rule out the hypotheses of overload in a poorly structured building. Note the connections between the slabs and the columns. Up to seven consecutive levels were clearly detached. Of having had beams or at least capitals, the disaster had been avoided.

@@pabloviadas7564 indeed

Wasn’t there work on the roof ongoing at the time prior to the collapse? Some residents were complaining about the noise of the work I believe. I’m curious what type of work was being done up there.

The problem was not just that machinery. There was a huge accumulation of air conditioning equipment as seen in photographs. A normal building could charge it without problem. But if you observe the structuring, the relationship between the slabs and the columns is precarious. It is most of the lack of capitals or even beams.

@@pabloviadas7564 There was no accumulation of air conditioning equipment. Everything you see was there in the 1979 plans, in the same general locations as originally built. Most of the units will have been replaced over the years, but the overall load and the way it is supported by the roof slabs and columns is largely unchanged. It is highly unlikely to be a major factor, unless the original design was catastrophically bad but somehow took 40 years to fail. Even the new big HVAC is likely irrelevant, as it combined two separate units which came to about the same size and it sat on the same 4 columns used for that since 1981 (two of those columns are still mostly intact, supporting the middle of the surviving northern end). Everything (CCTV, witness statements, etc) points to the collapse starting in the outdoor patio / plaza / pool deck, or in the basement garage. Lack of critical maintenance appears to be the primary causal factor, allowing major structural elements to fail, although the design and construction may well have had issues which contributed.

Each of these AC condensers weigh about 150 pounds each. They aren't what caused the collapse. Not even close.
