Miami Condo Collapse: More Contributing Factors, Root Cause

Рет қаралды 163,499

Күн бұрын

In this video on the Miami condo collapse we will discuss additional stressor s and contributing factors that may have had a role in the condo collapse of the Champlain Towers South. We know that the palm trees disappeared sometime around 2018 and we don't know if they were pulled out by heavy equipment that maybe should not have been on the pool deck, or if it was from a weekend pool deck that got weaker when the trees toppled these are questions that we need to find the answers to.
The Champlain Towers South condo complex collapse was located at 8777 Collins Ave. in Surfside, FL, which is just north of Miami beach.

You are amazing to listen to. My dad is an architect from back in the late 60s 70s so I was around draftsmen...and the hatted lawsuits of leaky roof days (let's justleave that for now). .But,.... you are one of the finest engineers I have ever seen. I agree with yr complete theory of what happened and more than a theory but you hit the nail on the head with all your points of reasons this fell. My heart just bleeds for the victims and the family friends and all. Still in my prayers . I also pray EVERY CONDO OUT THERE IS STEICTLY CHECKED OVER BY SOMEONE OF YR CALLIBUR FOR SAFETY AND THESE BUILDS SHUT DOWN IF NO UP TO PAR. Your view in the extra weight by each owner's remodels is also dead on. This should be seen as an issue throughout ALL condos and owners to stick to higher guidelines when doing remodeling. There needs to be weight limit set on all ALL type upgrades no matter what it is. My question is this....if they would of shored up under the structure down in the garage until further repairs and testing could of been done....would it of kept this disaster from happening. ??? Great work brother and GB you for all yr HARD work. Sis Monica

Jeff, in one of your first videos I brought up the point about newer updates to the old original materials. I worked for years cleaning condos and many original units had Plexiglas shower stalls, ugly partical board cabinets and 'orange peal' paint on decks. The old stuff weighed less than granite and marble. I asked different managers how the buildings could hold all that extra weight. Many things together may have caused "the perfect storm" scenario. One thing that may not have been thought of was that during our frequent hurricanes here on the gulf coast is that the intense wind causes the rain to be driven sideways. That would've forced even more water between the floors and layers of tiles. Knowing what I know about them, you couldn't give me a unit. Keep up the great work. You have the most sensible narritive of all.

Interesting Jeff at 11:00 you are talking about weight of improvements. I also thaught about the weight of all the natural stone floors in every room in every condo! You know in the 80s it was all carpet and cheap ceramic in the kitchen and linoleum in the baths. You know that they had to level the floor first, then thinset, and grout. That's a lot of weight. So I guess adding weight to a structure that's failing with basically rotting rebar. Ooof scary. You sure think of everything! I like it!

@billj5645 2 жыл бұрын

Adding a granite floor or granite countertop is a very small percentage increase in load, you can do the math yourself. There is always the concept of the straw that broke the camels back, but we have evidence that the failure initiated outside of the building.

@@billj5645 it is unkown what percentage of the cause was due to increased loading on those columns. Also, not really... those are such small columns, spaced rather far apart, and also at least 13 floors. You do the math, what was around 136 condos plus the common areas. That's a lot of square feet of natural stone, marble, granite countertops, etc. What may not be a factor though is that the average weight of humans went way up since 1979 and everyone was at home sleeping with all their cars full in the garage.

Ever since I started thinking about it I sometimes worry about the weight of the furniture, myself, and the weights and bench in my upstairs room, as I find it surprising that just a regular wooden floor in a regular house can take all that weight. So sometimes I'll get really paranoid about the floor collapsing. Yet I don't really think there's any more weight in there than most other upstairs rooms in other houses. So to see all that heavy marble and granite throughout the condo, it makes me think 'Wow, that's pretty extreme!'. I would not feel comfortable being in a place like that.

@@cathyclark6652 Correct! Because if tremors and earthquakes can effect buildings built on the Miami coast that already have damage from water and chlorine and high water levels, storm damage, sand beds instead of rock beds then many buildings are in jeopardy possibly! We need to know for peoples safety whether this is an additional threat to high rises , condos, or any other building in that area! When buildings have been through this in addition to storm damages and such there is bound to be some damage and with the building having settled over time as well then the differential stress on the building would be worse during an earthquake or storm situation than it would during regular times and since settling doesnt occur evenly it makes the building less sound over time! All these things must be evaluated and changes made to design as well as where a building can be and how high it can be and such when built on sand ! Also what the video said about the heavier materials added to the building over time without regard for weight and apparently not engineered but done as just a home remodel to a single story dwelling!

@@Funsho97 I live in a condo. We don’t vote on repairs as owners. We vote fir the board and the board makes decisions on maintenance and repairs. They also should be reserving fund’s for maintenance like roof, paint, driveway maintenance, pool resurfacing, etc. those major repairs should be budgeted for reserves every year so that when it needs to happen, you don’t get slapped with a $100k assessment like these poor people did. Their board was clearly negligent at surfside. I’m not entirely fond of the board where I live but they are fiscally responsible with money. Trees come down when they are dangerous. When I remodeled my kitchen, we took out a wall but kept the load bearing support pole and one board member questioned my . Why not take out that pole? Well we got the drawings from the county and it points right to the pole “load brg “ so we kept it. Apparently my neighbor across from us remodeled the same kitchen and took the pole out. Our board had surveyors out in the property a week later. That is what a responsible board does. And that leads to another point, as Jeff points out in this video, how many people remodel their condos and do whatever they want and have no idea how it affects the integrity of the building as a whole?

He mentioned that he is not being allowed on the property any longer, along with their engineer. He said he raised the issue in a letter to Mayor Cava, but in her email reply, Surfside's Mayor did not agree at all as to why they can no longer investigate the site. The Mayor says that the Surfside engineer is no light weight; he investigated the collapse of the World Trade Center hit by the Jet, and the Tamiami walk bridge collapse. The Mayor also mentioned that the Federal investigation will take years, and he wants answers ASAP. Like your analysis; great work you've done !!!

Jeff, I respectfully submit that your drawing doesn't show the reason for the beam under the flower box/planter....the building actually juts out at that point, in that area and is supported by that beam. The beam was not to support the planter. What collapsed first was the outside deck which took that beam along with it and then the jut-out came down shortly afterwards. All this happened in a progressive manner. Once that facade came down it brought the outside wall along with it which then progressed to the rest of the structure. Sort of like dominoes.

My question is about the shear walls, maybe we have more code requirements here due to having to deal with seismic activity, but they are also supposed to help a building stay upright in high wind situations, I believe. Now while neither of those caused this collapse, building codes in seismic areas often require shear walls in more places then I seem to see them on the plans that you show. In this area the idea of shear wall are that if a great enough earthquake occurs that the building starts to collapse it will only collapse to the shear wall, and we see that in this collapse the shear walls at least in part of the building did stay up even though the forces were enough to sheer away floors and walls when the pool deck collapsed and then those pulled down other parts of the building. It seems like if they had placed, as out codes would mandate a shear wall in the area behind the lobby running east-west, when the pool deck went it might have taken down the front of the building that did fall first and then have stopped allowing the back part of the center section to remain as well as the eastern side of the building. It just seems to be that the plans did not have the shear walls that should have been placed that would have stopped so much of the building from falling instead of just normal walls that could not bear the load and fell forward towards the pool deck and pulled down by the from when it fell. I just wonder if this was a design flaw of sorts as probably code there does not anticipate seismic issues, just hurricanes. I also have to wonder, when you showed some of the major renovations that were carried out in many of these units - to renovate do they not need permits and does not the city and/or the HOA have a say as to what can be done or materials used for renovation taking into considerations of what the units were rated for in weight and calculate how much more weight can even be added to a unit, or in that area is there not too much oversite in this way. I actually went and looked at some other real estate photos from units for sale or sold before the collapse that has been renovated before the sale or going on the market and actually saw one where all the carpet was removed and marble was put down pretty much throughout the unit making me think that with all marble floors, as well as countertop, bigger and heavier appliances as well as solid wood cabinets that that unit may have come close to adding almost a ton to that floor. I suppose someone calculated whether the building could hold that and not crash down into the unit below, but if you had many units that were at or slightly over their weight limit (not to mention heavy furnishings) once the building was unstable would that extra weight not tend to pull the building over if one side of the unit lost support?

Jeff - Thanks for another great video! I really appreciate your ability to analyze each new piece of evidence that comes to light, while being cautious to not overstate its significance before all the facts are in. My one suggestion is that maybe it's time to do a sort of "roundup" video of what we know so far, how the facts interrelate, and what important facts remain to be learned. I've got to admit that the jump from palm trees last time to the deck resurfacing this time was a little jarring, although on reflection they both relate to the same two key issues: what circumstances may have compromised the strength of the deck and columns, and how much weight were they being asked to bear. But for me at least, a look at how the pieces of the puzzle fit together (so far) would be welcome at this point.

@petercofrancesco9812 2 жыл бұрын

Usually the cause is simple. They neglected fixing a know issue of water drainage problem with the deck. But most people are only concerned with cosmetic repairs and saving money.

Not necessarily, you have all that weight pulling on a column it could be in tip top shape and would collapse. The columns are designed by physics to support the load on top of it not to the side, its why they flat up collapse if something pulls on it or someone crashes into them with enough force, they're stupid string vertically, extremely brittle in comparison horizontally. It's why we need shear walls and other horizontal reinforcement, so a strong wind doesn't just blow it over like the big bad wolf from the three little pigs.
