You are able to present your analysis in a comprehensive way without one of the so-called professionals interrupting.

There's tons of ethical, professional experts creating incredible and highly reliable content on KZbin. It's a fantastic educational resource for any field. Unfortunately, there's also no shortage of creators spreading inaccurate, potentially harmful information across the platform. Sometimes this occurs as the result of the creator overestimating their knowledge level in the topic (for example, if a university sophomore majoring in structural engineering tried to make a series comparable to the one we are watching). But it's most often people with zero background in the topic saying things "outside of the mainstream" (for example, the numerous conspiracy theory videos on this incident). Of course, this is true of the entire internet. We have unprecedented access to all of the best information in existence... But we also have unprecedented access to all of the worst, most unreliable information in the world. And oh can prove very difficult to determine *which* information is quality. The inaccurate videos tend to be far more sensationalized and intriguing to a wider audience, which can be dangerous. I hate to speak unkindly of your field, but broadcast information steadily became increasingly sensationalized over at least my lifetime. This is obviously far less of an issue when information is being appropriately sourced and thoroughly fact checked prior to broadcast. But I suspect that it has caused a lot of confusion in the general public about who to believe on the internet. Highly sensationalized and dramatic content created by the public is a red flag for unreliable information in this setting. But it doesn't feel like a red flag considering the captivating way that so many broadcasters et al choose to present reliable information. I'm not sure if that makes sense. But the best solution to the internet information paradox is to continue trying to educate the public on how to spot user-created content that is reliable. This channel is a great example of one that hits countless "green flags". We know exactly who this person is and we know which company he is affiliated with. It's easy to look into his credentials and see that he is highly qualified to discuss this topic. His tone is not at all sensationalized and he clearly explains the limitations of his access to information. He's also careful not to speak in absolutes, as absolutes would be highly inappropriate at this phase of the actual investigation. He provides links to all of the documents and other forms of forensic evidence in all of the videos, which helps minimize the odds that any particular bit of information has been taken out of context or completely fabricated. His easily identifiable credentials and expertise grant him the ability to explain structural engineering concepts, including ideas about what *may* have happend -with appropriate disclaimers-, without needing to provide outside sources to back up his explanations. This is all around a great channel for anyone who is actually looking to understand the broad picture. Those who are looking for morbid entertainment and *SHOCKING SCANDAL* rather than education may not stay on this channel long, but thankfully there is an ever growing number of people who are supporting the channel and getting reliable information.

I appreciate the way you are treating the enormous amount of speculation. You are explaining what science is involved in each theory, while also making clear what is fact and what is theory. I found you because of my (admittedly) morbid curiosity. Because you are so good at explaining the concepts involved, I'm actually sort of going to school and learning new and interesting things. I think your work must be fascinating because it’s so interdisciplinary. Geology, chemistry, materials science, physics, math and so much more! You would make an excellent teacher. I appreciate that you’re taking time away from your family vacation to wield science and logic against our national problem of speculation and rumor. I think your work is also clarifying the crucial importance of building codes and their enforcement. Yes, on good days those regulations are probably expensive and onerous. This tragedy reminds us that onerous and expensive is better than dead. I also thank you for your commitment to remaining silent until you have both something worthwhile to say and have researched it properly. Very little good can come of this awful tragedy. It seems you are doing your part to help us learn, and that’s a good thing. Still would have rather the building stayed put.

I live in a similar structure and can tell you that we have more than considerable ventilation in our underground parking, along with numerous large floor drains throughout. With the amount of drainage provide we would never see a large accumulation of standing water. I would be curious to know what the actual building plans indicate regarding the level of ventilation and drainage required? Standing water in a below grade facility will obviously create issues, even if clean versus salt water. Just consider taking a shower without the bathroom fan turned on, water drips off the ceiling in that example. Thank you Josh for your analysis and clear presentation.

I’ve been in industrial construction my entire career and worked in nearly every state in the union, with a 3 year stint career change, of doing mid & high rise form work (concrete construction) in central and primarily, South Florida. I’m now back in the industrial construction realm and for a reason…SAFETY! I’m a HSE professional and with the quality of most (not all) trades and contractors in south florida, lack of education, training etc..it made me nervous to walk my own projects in Ft. Lauderdale, Aventura, d-town Miami, you name it and this was all within the last 5 years. I’m not saying poor quality is the cause, as I’m not there and even if I was, it’s too early to determine. But, given what I know of the craftsmanship and sink holes in Florida, I’d be absolutely shocked if both weren’t THE dual root cause. Though by textbook, you’re only supposed to have one root cause and multiple potential indirect causes in any investigation, in the construction world. However, I think this’ll be the exception to the rule. God bless the victims, families and those “awful” first responders, risking their lives to try and save someone else’s.

That is really useful data. Disturbance of nearby soil absolutely could cause be the root cause. People here seem to conclude its corrosion and poor maintenance. However, it could very well be erosion leading to a broken foundation, leading to column damage, then spalling and rusting. What people are noticing very well could be a result and not the root cause. Residence should be able to confirm structural damage around the time of new construction or within a year or two later.

Location being what it is, you could literally list condos in those buildings with "3 bed, 2 bath, non-zero chance of death" and people would still pay ridiculous amounts of money to buy them. I suspect a number of tenants of this building knew it was in terrible shape. Maybe not to what extent, but if you told them, "hey we're really concerned about the condition of this building, we need you to move out so we can do some really serious renovation/repair work. It isn't safe for you to be here while the work is being done" I'd bet good money a large percentage of them would have been quite pissed and told you to go scratch.. Or threatened lawsuits, etc. I know this because I've dealt with it before working in real estate. People will tolerate INSANE things to live in a desirable location.

Looks like the columns have not been redesigned for the extra live and dead loads. I don't believe this have been a contributing factor, but I wanted to point it out. Also, a huge steel structure (freshly painted in red) can be seen on top of rubble coming from the middle section of the already stressed roof, may be installed to hold and HVAC system... more unaccounted loads!

Under the a/c units are lengths of red painted metal supports to hold the units on the building, but attached to the building. Photos & description were about the possibility that the roof fell first. Early photos of the debris shows those red metal bars & ladder to access the elevator room on top of the pile. That is evidence that the roof didn’t come down first but last.

I'm late to the game on this and not as smart as the guy running this channel, but I have experience in construction including running a site which was situated over less than optimal ground conditions (it was found to be a historic landfill the conditions of which led to a redesign of the foundations mid-project). It seems that the timeline for the condo collapse starts at about 21 minutes before the building fell when the video taken by a couple next door showed chunks of concrete and a pipe pouring water, all located in the parking garage. My guess is that a post tensioning cable had finally rusted to the point where it failed, inside the first floor slab, causing the slab to "slouch" under the weight of the planters, etc. located in the pool area. About 14 minutes after that from what I can tell, is when the pool deck fully collapsed, vertical supports punching through the slab and the weight and position of the slab now putting horizontal pressure on the three supports which then failed shortly afterwards. The shaking in the building and the sounds could have partly been created as the post tensioning cables popped, one by one, leading the entire building to shake as the first floor slab was compromised.

@@BuildingIntegrity Thanks. I also noticed that the building manager stated that the water intrusion occurred in the parking garage under the collapses section of the building and that the part of the building that remained standing did not have an issue with salt water intrusion. The manager said that he brought this issue up repeatedly and that the owners said that it had been that way for years. So for years the sea water flowed in with high tide and out under that building creating a bigger and bigger void under the building. The 2018 report did not mention this root cause issue and instead only mentioned that they saw a some cracks here and we see a leaky planter box over there etc. The building manager repeatedly told the owners that it "was not normal" to have all of that sea water in the garage. He was ignored. The owners response was don't worry it has been like that for years, just keep the pumps going to keep it drained was nonsensical. It would appear that the engineer in 2018 was not even aware of this issue. I would assume that with all of that cracking the engineer probably should have called for a more thorough inspection and he probably should have contacted the building department. Also why are these buildings only inspected every 40 years?

From Japan. In the past, Japan had a shortage of sand for concrete due to the construction rush associated with the rapid growth in the 1970s, so some contractors used sea sand that had not been washed thoroughly. The salty concrete corroded the rebar quickly, which expanded, and after only 20 years or so, the concrete began to peel off at railroad overpasses and tunnels. It is the same as what can be seen in the Google image of this building before it collapsed. So the railroad company spent a lot of money to repair it.

When a lot of people say the same thing, especially people that are not associated with each other, there tends to be some truth to those comments. When a building that’s inland (vice being built in the ocean itself) gets seawater inside the underground parking garage, there’s a very serious issue that if not fixed, will eventually lead to the collapse of the structure itself. Concrete is not completely watertight, thus, it takes a thicker wall to keep water from penetrating. If there happens to be rebar that’s within the range for which salt water can penetrate, than that rebar is going to swell up like particle board…from the expanding rust. If the concrete cracks for any reason, then water can penetrate even deeper, weakening the concrete further.

If the consensus says that there was seawater around the support columns then the consensus can be that it was causing corrosion in the support columns. The consensus can also be that the movement of the water can cause erosion. The consensus can also be that both were occurring. The consensus can also be that a reduction of strength of support columns can lead to a lack of support. The consensus can be that gravity is found everywhere and that objects that are not supported will fall until they reach something that can support them.

Water pooling in the garage could indicate that ground water. The water could have been displacing sand, soil, or whatever material is underneath the garage as water level rises and drops. If this happened at low tide, then it could be that the water displaced a little more material. And this time the hole was big enough to cause columns to finally give way. This is a single point of failure problem. Those 3 columns could have all failed at the same time with a sink hole. I don't think corrosion is the root cause. The pictures of the spalling don't look great but don't look catastrophic. Corrosion is unlikely to make several columns fail within a second. If this were a collapse over a day or two, I could beleive corrosion. With the video of rescuers in the garage, they should be able to see if those 3 beams broke or not. That would be really good data.

@@MrJamyang24 if you think that. Then clearly the design must have been flawed. That would be bad engineering practice. Two columns should have no trouble holding up the 1 failure, at least for a while. Yes, there is evidence of corrosion, but consider that columns are over engineered to handle much more load than required and there should be evidence of rapid deterioration when heading to failure. These things don't just suddenly snap. The rusting metal needs to blow out big chunks of concrete before such failure. Someone would have noticed if deterioration continued over time. I wouldn't rush to what you think is likely, but to think about what could have happened. Think single point of failure with cascading failures. I would hate to think that corrosion may lead to imminent failure or else there are many building that are about to drop. If that were the case, every structure by the beach is in big trouble and people should be worried.
@MrJamyang243 жыл бұрын
Yes, the design was clearly flawed! Factors of safety were inadequate to compensate for the aggressive corrosive effects and the poor understanding of the soil mechanics. The 2018 survey found serious damage to the structural integrity due to corrosion in many of the structural components . With chronic corrosion at the lower levels of the column outer line, buckling and eccentricity loading burst these three columns for the expected reasons cited in 2018 Survey. The facade sunk and tore most of the rest of the building with it as it experienced forces never intended to be felt by the surrounding structural components Basically, all the columns at lower levels had weakened and could not carry the additional loads caused by the spectacular failure of just one.
@coolpix2223 жыл бұрын
To be honest, I think corrosion is not good and spalling is not good. But, based on seeing the video and other evidence, my professional opinion is that there was a catastrophic event that took place in the middle of the parking lot at those columns. And certainly corrosion could be a contributing factor. But as I hear today that there was construction next door in 2015, and complaints of structural problems to the south tower as a possible result, that is what I listing is the top of the list for root cause, 2nd is failure to understand the water problem in the garage. Water up and down with the tides should have been a massive red flag. That could only mean bad news and something people cannot see. They needed to bring in sensors to check the ground beneath. Probably it was next suspected nor checked. Flowing water leads to erosion and thus could have left a void, as I call it a sink hole. The up and down displacement would have moved the ground under it. The question is how long has that been happening? If for a long time, its not likely the construction next door. I believe that spalling and corrosion are the result of something else. It is possible that those beams were sinking and thus spalling appeared followed by corrosion. They could also be two independent problems. Corrosion is extremely unlikely to lead to a catastrophic event in this case. Many people would have saw big chucks of concrete falling off and often before the columns just give way. But as someone said, the beams on the fallen part were much smaller. That could mean it didn't have the load margins that the other side had. So, it could be a few contributing factors and a catastrophic event like a sink hole or void with cascading failures that immediately followed. This isn't going to be hard to figure out one they evaluate that center section of the parking lot and to see if that around sunk in.

>If the maintenance were done would it have supported the building and prevented the collapse? Hmm this is what im wondering too. As per the report by that engineer in 2018, the slab that goes from under the pool all the way to under the building was being weakened. So I guess they would have had to put something in place to keep the structure of the building maintained because the report said the entire slab would need to be replaced since it has *already* significantly deteriorated. From putting it all together (including the report from the lady who was on the phone to her sister when it happened..... The lady on the phone to her sister (this lady wouldve effectively been above the pool in one of those close to the pool condos, said that "pool was sinking". Given that slab goes from the pool directly under the building where she would've been. which also lines up with how the building collapsed on the video.... The slab failed (but not fully) but we can see the area around the pool has failed, and that the pool area has been lowered during the collapse. I guess the slab was strong enough to resist a "light" pool, but could not stop the dynamic loads of the moving building and disintegrated. But it would appear the failure originated from this slab where water would pool.

Morabito Engineers identified the problem in their report. They stated that the pool deck hadn't been laid to a fall and combined with a failed water proof membrane, the slabs structural integrity was compromised. The weakest spot on the pool deck is likely where there is ponding where the slab had sagged, discernible by the damp pavers near the swimming pool. This area corresponds with the largest span of the slab between narrow columns that have punched through the slab. Additional loading from a likely saturated planter next to the building combined with pooling water found the weak spot; the rusted out connections between slab and columns. The North Tower pool deck has been rennovated. Let's hope they caught it before that structure was compromised by water ingress.

I'm so sorry for all those lost, and the families impacted by this tragedy. I'm watching videos like this to help me understand why constructions failures happen and be more aware when I'm on construction sites. In your previous video you identified what you thought were Post Tension Tendons. Those were likely electrical conduits running within the decks. P-T Tendons, whether Uniform or Banded would be in groups for a multi-story building as they act as beams to carry the slab load. You would only find single tendons in home construction for slab on grade concrete to mitigate cracking. The foundation plan in this video is interesting in that the section of the building that did not fail is separated from the sections that failed by what looks like a shear wall at the elevator core. That would lead me to believe that the shear walls (basically long support structures like one long column) did their job in holding up that section of the building. One could deduce that column failure (for whatever reason) around the ramp and separated by that shear wall caused the failure of those other sections. Also, if you have ever been in a parking structure as cars drove by you would notice a bounce in the structure, this bounce causes a cyclical type load, so the load on those columns near the ramp is not static. Cyclical loads are more critical to the overall integrity of the structure.

Hey Building Integrity, A previous manager from the building recently explained that YES every high tide the Parking Garage would flood with water, He said it was a constant issue and they tried to use pumps to remove the water but could not keep up with the levels & yes it was Sea Water! here is the video the former manager speaks towards the end ... kzbin.info/www/bejne/nZmalKGPbLWegrc

@Oh Happy Day Because they paid a ton for the condo & also could possibly have a signed agreement or something along those lines keeping them there, I know for a fact they were paying $800 for + amount of years to cover "maintenance" which we now know is BS & someone was pocketing the money.

Thanks for taking the time to give us these clear and no BS explanations, much appreciated... and a thousand times better than the "news" (MSM). Enjoy your vacation!
