What Secrets will be Uncovered at Champlain Towers South Collapse Site? We look at its Foundation. 

I so agree. Sad that it took the collapse to give us this, though… I hope this channel will continue to grow and present more in depth lessons like this one.

Civil Engineering is the King of all Consulting Engineers. This is it.

@@MegaSnow121 Sadly there are many building collapse's all over the world, so he will have plenty of material to make videos.

Thank you! That means a lot!

@@BuildingIntegrity I hope you do some video on the FIU bridge collapse soon.

It really is incredible. I look forward to these videos and set a good time to watch them.

You're right, but many technical professionals who can communicate well become managers.

It is also a perfect example of terminology being thrown out by the media that turns out to be so misleading it is erroneous.

@@KameraShy 100% usually I hear some sound bite on the news and then I have questions about a specific phrasing and it takes me HOURS to figure out what it might refer to. I wish the news would have a statement after certain clips like for more “free” information about terminology and specifics. I do like that some local stations have started streaming some stories and answering viewers questions live, definitely a move in the right direction.

When you focus on logic and common sense and not emotion and guesswork, it isn't hard.

Well said!

And let’s hope it may inspire more passionate folks to go into the industry. What a preview for the importance of always doing your best and to keep learning.

Everyone but the builders themselves.

Yes! Mr. Porter, you need to be teaching professionally (if you’re not already).

I was thinking much the same.

Exactly the same sentiment.

I concur I'm fascinated with all of this

Me too. Great presentation.

I agree completely. I’ve seen a number of people talking about what happened here, but these videos have been by far the most informative and educational.

Yesterday I watched 4hrs of these back-to-back (I wasn't well and needed to fill my time with something stimulating). I'm an arch. tech. and this is fascinating to me as someone in architecture. Certainly, a lot of the terms mentioned are things I am familiar with, but I graduated in 2019, and this chap is far more engaging as an educator than most of my lectures. He's on topic, he's clear and concise, and he always has a reference for the things he says, and his supplementary visuals are clear and explain what he says, not confuse it.

Ditto

Thanks for corroborating. May Allah (S.W.T.) bestow upon you His Blessings and Guidance.

As a P.E. (Professional Engineer) from California, I agree that this series of analysis "from a distance" is right on target and is a great educational series. I feel the regular flooding of the basement is a key to this tragedy and the explanation given could likely be found to be the cause. There are a few other possible scenarios related to the flooding that could also be contributing factors.

What do you think he is doing now?

Wow! Do you have any pics of the water appearing in places other than the collapsed condominium?

Which eventually washes away the ORIGINAL foundation, ergo building becomes unbalanced and collapses all due to Climate Change.

I feel the same way! I've learned so much from watching his show. He's great!

Yep, he's great at explaining, how a building is build. But let's take it one step further: If the building was rotten at the underground pillars, then it should have shown ample signs of deformation, which it didn't, and should have fallen over, not collapsed in it's own footprint, like we see at a controlled demolition.

Those drop heads at columns looked pretty lame compared to what we do in So Cal, 416 retired.

@@roddiener agreed. Californian’s coastal buildings are engineered to survive constant seismic movements, as the Pacific Plate slowly slides to the north. Their ferro-concrete pilings aren’t catastrophically failing.

Sheraton hotel here was built 1000x better than this building. You can see the ambit of rebar and the thickness used was much different to thus build. Had they done it using the same method that building would not have fallen down. Note Both were built in the beach here, just in different times

The garage floor survived intact. As a layman, I find that incredible, that so much fell on them and so much heavy equipment but the floor looks perfect. Can't tell the condition of the columns but clearly doesn't look like a foundation failure. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-hsmqBJj-Q1Q.html

@@yosefmacgruber1920 - Nobody, literally no one, believes that natural immunity and herd immunity are unimportant concepts. You're just confused.

Yeah. If you ever watch the show Mayday (Canadian show, may have different names in other countries) where they explain air crashes, it is almost always the result of a chain of events. If any link in the chain hadn't happened (eg. mechanic hadn't used the wrong screw, pilot hadn't ignored a fault indicator), the crash wouldn't have happened. I can almost guarantee that when they put the whole picture of this collapse together there will have been multiple occasions where if someone had taken the right corrective action on one problem, the chain would have been broken and the whole disaster would have been avoided.

Things like not letting big palm trees sit on your garage’s roof for a long long time?! Holy 💩 I don’t want to see big trees of any kind 50 ft near anything I live in now.

The beach was a few hundred feet away from the building on the east, and it was downhill to the beach. On the west side, the intracoastal waterway was a few blocks away.

The parking garage is not a habitable level, so doesn't count as a 'storey'. How many Developers over the years were voted into Local and State Govt.? TOO MANY! THIS is why exceedance on height/storey limits happen.

@Randy Carriere A boat? He had a yacht and a big one to boot....Just guessing

It tends to be liberals that hate to listen to facts because it hurts their feelings.

I down voted this particular vlog because I think he's really stretching on his ideas. He's seeing boogiemen everywhere he looks. Sure, there may have been differential settlement and maybe a void space, but the visual evidence shows relatively minor issues before/after the collapse near the foundation/basement slab. The cracks in the basement slab do not appear extensive (not enough that would lead any engineer to conclude there were serious, structure-compromising subsurface problems). Nor did the building show the telltale signs of distress that you'd expect in such a structure if what he is suggesting was actually happening. (if there were signs of meaningful differential settlement, they'd have likely installed piezometers/inclinometers and been monitoring the building closely - the consulting engineer in 2018 would surely have made mention of signs of differential settlement - but not a peep was made). He's dumbed-down his explanations to suit an uneducated audience, so it all sounds plausible to a layman. To someone who's in the business and done lots of foundations/concrete work and repairs on structures, I see a lot of dubious statements. What we have seen is ample evidence of the pool deck and plaza deck leaking like a sieve over many decades, causing significant spalling and corrosion of the slab. We are all-but certain the initial slab collapse was centered around the leaking planter area - which jives perfectly with the photographic evidence prior to the collapse showing extensive leaking/cracking of the slab in that area. We see almost no evidence of any damage at the basement slab/column interface now that the debris removal has exposed the basement slab - all the columns look good - if his conjectures were anywhere near accurate, we should have seen twisted/buckled/damaged column bases - but we simply don't. His other vlogs are excellent and I've upvoted all of them. This one had me shaking my head repeatedly.

@@rebeccacarraway480 I'm sure that's an entire other onion of it's own.

It's so obvious a lot of those guys are just watching this channel and then trying to present the info as if they knew it themselves. In reality, their videos are literally just like really bad book reports from 4th grade. It's basically atrocious "video-plagiarism." lol

NIST are pros at covering up controlled demolition so yeah not surprised here they are again.

@Hypercube Jones there are obvious detonation flashes. All sections of the building including the known demolition fell at free fall speed directly into their own footprints. Flashes before the initial collapse were the same time before the collapse. And just in case you don't know, it takes months to prepare a building for controlled demolition, not a day and a half nor even 10 days. That fact can be found in numerous places including Wikipedia. By the way, a natural falling building have 360 degrees around at which to fall. But all 3 sections fell directly down. The one and only way to accomplish what we saw originally was controlled demolition. Naturally falling structures also take longer than free fall speed. Pancaking floors, if that is even possible would take much longer than free fall speed. Every last floor truss would have to come off of every last column at the exact same time for the building to just drop at free fall speed. Don't be naive or stupid. The news lies. Rich people do horrible things. Rich people pay people off. And besides that, look carefully, there were no lights on in ANY of the condos, not in the "accidental" collapse or in the remaining condos on the other side as per the original video. Not one. Not one. So at 1:30 am EVERYONE was asleep with ALL the lights off? Really odd. Also look carefully at the remaining building before it's miracle time controlled demolition, ZERO patio furniture on any of the balconies. NONE! Not a lounge chair, table, chair, plant, bicycle, NADDA. All of this adds up to no one in the building. A planned controlled demolition and a lying main stream news media for views. Or a massive insurance fraud. Bet they build a 3 million dollar per condo unit next, because a poor 3/4 million dollar condo just ain't cutting it. It is beach front property. Follow that money and watch. Bet it's not gonna be a memorial site. Just like 9/11 ground zero...PUNK.

@@sundaywhiterabbit7679 show me a link to ANY video you've seen that shows detonation flashes, and we will do a frame-by-frame analysis.

@@nobodyknows3180 the ONLY one of the building collapsing. Detonation flashes going off all in the dark condos at precisely the same time before the collapse as the known controlled demolition. You find me a shred of evidence that a 12 story building can be prepared for controlled demolition in a day and a half or even 10 days. Not possible. It's crazy to believe that all 3 sections fell in 3 seconds which is exactly free fall speed strait down into the property. 3 sections because they are actually 3 seperate buildings, they have to have 2 hour firewalls between them at so many feet at per building code. Out of 360 degree direction they all 3 fell strait down, not over to the side at any angle. Free fall speed is only accomplished by separating every floor truss from every column at precisely the same time, otherwise the collapse would take longer than 3 seconds. I can find a video of a naturally collapsing 2 story grain silo that takes 6 seconds to come down. No trusses connected to columns just a shell of a silo takes twice as long to come down and not straight down. This all has every mark of controlled demolition. All other theories that avoid the topic are ridiculous cover ups for whatever purpose it was done for. Please for the love of God don't think wealthy people wouldn't lie, kill people or conspire to commit fraud or insurance fraud for some gain. However, I have very serious doubts anyone was even in the buildings at all. See there were no lights on in any of the apartments, as seen per the original collapse video as well as the one recorded minutes before. So no one in the entre building left any lights on at a mere 1:30 am? Odd to say the least. And as viewing the known controlled demolition, there isn't a single piece of patio furniture on any of the balconies. Then on top of that the news never showed the owners walking out and evacuating with their prized possessions. But they did catch residents from another condominium being evacuated and interviewed them. Odd don't you think? You gonna buy all the bs the news produces? They are government controlled and have all the tools of Hollywood at their disposal. Would they? Because it's more than obvious they COULD. which is so dangerous for all Americans to afford them such great power. We will literally believe ANYTHING they put in front of us. That's obvious too. What if Stalin or Hitler or Mengola had this under their power, what kinds of things might they do? I bet they will not build a memorial for all the victims there, my guess is an even more expensive luxury beachfront condominium.

@@sundaywhiterabbit7679 Don't forget the fact that there was a "deep fire" reported within the rubble which was supposedly hindering rescue efforts.. The fire/fires could have been from incendiaries or explosives.

That's what I was thinking....

Yes, I notice that too on beaches in California. I guess it is common on all beach front property. I forget how far away from the beach/water edge the tower was. It was mentioned on another channel video right after the collapse. Some people in California build houses right on the beach. I would not want one of those houses. I have seen how severe storms, not hurricane force, have swept away entire beaches, damaging houses built on the edge of the beach.

@@rollothecat2010 i think they said it was like 400 ft or something. Very close.

@@dafungusamungus6742 Thank you. That is far enough to not be a factor in terms of beach damage reaching the building. However, I do not know anything about hurricanes. I have been through tropical storms here and also blizzards when I lived in the Northeast.

@@rollothecat2010 yea man it was a weird ass building design. Why did they have the bottom hallowed out and standing on pillars? That just means if one beam fails they all will. There was no redundancy since that will drop a section of the building. They just assumed none of the pillars would fail. And boy they were wrong.

I understand that the residents of Champlain North (same construction) are somewhat concerned, being only 70 feet away.

As you and the OP stated that the garage floor water is most probably ground water intrusion, how would one propose to protect the underslab support structures against corrosion in area subject to high hydrostatic pressures? The vertical walls can easily be protected by using stub wall off slab with a keyed/waterstop joint and coated exterior, but how can you get underslab? Was the basement slab poured on "grade" or was it formed?

great point

I think that the water in the garage was due to the broken waterpipes. But I do wonder how far do you dig in that area before you hit water? This is a barrier island so I would expect water table to be high anyway. When they dug the foundation did they not seal something properly? Uus that part of the reason there was always water in the garage?

That is exactly what he said in the video. Are pointing out that you agree?

@@bwtawny In my area, you'll hit water at 2-3 ft below surface. Deep rooting trees don't survive. Root systems don't grow into the ground, they grow ON the ground. Katrina toppled more trees than snapped.

Great point. Did they import and compact material to fill a void? Was there a moisture barrier of some type where the concrete was removed?

can't wait tell we get to see a new Seconds from disaster

Here is a quote from NatGeo's series Seconds from Disaster "Disasters just don't happen, they are trigger by a series of critical events...".

It's usually a chain of events. Break a link in the chain, the disaster doesn't happen.

Not every day it makes completed 40 year old buildings fall over, though :)

We don't even have basements in California.

Here in So.Louisiana, if you dig a 2 ft. Post hole and take a lunchbreak, you'll come back to a hole full of water. Building a 30ft. deep coffer dam is a lot of fun.

Absolutely - shiny things sell homes, a sound building structure is sometimes secondary. In London developers have been underpinning 3-4 storey properties to build garages below the ground floor, undermining the structure and that of surrounding properties - there have been a few collapses - and all for that valuable parking space.

Good thing I live in the South! A lot of places here don’t have basements.

I always looked for the utility rooms in the basements first. If they weren't using engineered joists but just dimensional lumber I immediately assume the rest of the materials uses were crap and skipped to a different builder. Model homes where walls in hallways wove in and out over inches were another thing that floored me. It's the model home - the one you are showing off - if they couldn't be arsed to square the dang walls in their model home what the heck would they slough off in my house?!? It boggles the mind....

Indeed!

@@BuildingIntegrity I’m so glad I found this we’ve been watching the water with the neighbor for a couple of days now and we were all asking this question. This is what we see ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Wl7xiMcYpQQ.html we also seen the columns before they were cut and the skinny pylons looked flat on top ?

@@BuildingIntegrity FYI did you see this eyewitness report from the engineers on site? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-YsWfNSnvRW8.html The engineers examining the debris are finding that the original drawings DO NOT match the construction (final product)... Where the drawing indicates 4 steel rods of rebar in slab/columns there are actually only finding 2 rods...? = A 50% reduction in "Building Integrity"?! IDK what to make of this data but I figured you would. Like, wouldn't this call into question many buildings of that era, regardless of ongoing repairs made or not? Bc the actual plans were not reflected in the actual construction bc obviously the inspectors were not checking these basics? Thx.

@@auntijen3781 makes one worry for the Champlain North Building

Agreed

That wasn’t the sole factor

Wouldn't you think they'd use self-watering planters? The large plastic ones for tomatoes work great. The water backs up the hose slot when it's full. Something like that would he smart and would at least greatly reduce the water. Tomatoes you have to water daily, but most plants are just once a week. If that. When it's humid, it's less.

A recent video pointed out that the subsidence factor for this condo was pretty localized. Nearby properties not affected as much. I'm learning as I go here but I'll try to find the link to the subsidence map. But if this video and Perrotis comment pertain, the implications for barrier island condo construction up and down the coast is too immense to total up!!!

There are other buildings in the area with flooding garages. They are at random locations.

I would like to know why the columns in the collapsed section were narrower than in the section that did not collapse.

9 cut&

I am in EU and I constructed a house. Now not comparable but before we started we received instructions and one was 1m above waterlevel, so we had a crowling space underneeth the concrete slab for pipes and utilities but not usable as a garage or basement (other areas do allow basement and or garage). Noted we where in a region with high waterflooding possiblility. So the way we construct changes depending on soil and water presence. Thanks to your explanation I better understand the why and the mecanics of waterlevels and the connections and influence they have on a construction and buildings. It gives us knowledge how to and what to look at when we buy a condo, but also to keep looking during the years how a building is reacting to the changes occuring and how it shows even is the cause is invisible.

Sounds like a possible sinkhole which flordia has something like 22k of them that we know about

@@protipskiptoendofvideoandr286 Most of the sinkholes in Florida are due to soil/water erosion of the limestone layer which occurs in many places throughout Florida. It actually dissolves the limestone. However, many places in Florida do not have this limestone layer just just below grade level and therefore traditional sinkholes won't occur in these areas. This property was built on sand with no limestone layer immediately underneath grade. If it had limestone underneath they would have simply drove the pilings down to the limestone and be done with it.

Caribbean islands have different geology than the barrier islands of Florida.

@@michellem7300 my problem now is, there had been numerous “fixes” done to this building.... some one knew the potential of these issues and nothing was done due to what I feel is greed.

How deep can the scans go? I have wondered how foundations and piles are checked after these midrise buildings have been getting thrashed on the beach for 30-40 years? Or how are interior columns checked that are covered up with kitchens, vanities, walls etc.

@@williammcginnis7428 Thermal imaging only shows surface temperature of the object being scanned. This measured surface temperature can be the result of the transfer of the temperatures from the inside of the object to the outside, or it can be just from the surface. If you place you hand on a cool surface and them remove it after a minute, you will see the thermal outline of where your hand was. If an object has a covering over it, or behind a wall, then there will still be a transfer of object's internal temperature through the external covering. But the actual surface temperature of the covering will be slightly, or significantly, different due to the laws of thermodynamics for heat transfer. Heat travels from hot to cold. I would expect the temperatures on a column that is severely saturated with water to be cooler temperature than a column that is less, or not, saturated. This is due to the effect of heat transfer from the saturated columns to the large mass of colder underground/basement flooded water. Also, if a column is saturated with water, then there would be temperature gradient starting at the lower part of the column (cooler temp.) and going to the upper part of the column (warmer temp.), or from the most saturated area to the less saturated area. Additionally, if a beam is saturated, then the thermal image will show where the moisture is entering and how it is spreading. I am not familiar with the current methods of checking of foundations and piles on building. My posting is just to offer a suggestion to incorporate thermal imaging technology to test the columns, floors, and beams of buildings near the water. An initial thermal scan can not only provide a focus of areas that may require additional methods of testing, but also provide a method to aid in helping to determine the condition of a building. This is a non-destructive testing method. Thermal image scanning provides immediate results.

The way he describes how the water table affects the soil would make you think that every structure built on the beach may have this very same fate

@@MaryMacElveen The answer for apartment owners might be don't ask.

@@nodnoc Yes, exactly! So I think we need a follow-up video. Is it common for voids to form? Is that always an issue? Are newer buildings better-equipped to deal with it?

It's an interesting word and an even more interesting process. I became acquainted with the process when we had to do extensive (and very expensive) repairs to the parking deck of our condominium. We had to support the parking deck from below and jack-hammer out dozens of rebar and replace them. If you have to repair all the way through the slab in even one spot, the inspectors may require that the entire deck be demolished and replaced, rather than allow repairs..... At the first sign of spalling, engineers should be called in to ascertain the damages & action should be taken to repair the problem before it continues to spread. Otherwise you end up with repairs costing MILLION$ of dollars as in this case.

Two two aren’t mutually exclusive. It can be both tragic and fascinating.

lt's still fascinating and the unnecessary loss of life makes it even more so.

If you go back to his first video on this topic, you can learn along with each video. Josh is a great teacher! Understanding how it happened can help us all be more aware so it doesn’t happen again. This gives meaning to the loss of those who died. They would want to understand it too.

You wouldn't even be checking this out without the building collapsing so...

@@N0xiety I think what they’re trying to say is that if they had evacuated the building before hand and it collapsed with no one inside, it would be fascinating, but because people died it’s not fascinating. Which is completely incorrect. It’s just as fascinating regardless. Because people were killed, it’s also tragic, but that doesn’t make it any less fascinating.
