  I have been watching a handful of engineers doing various analysis’ and speculations. While I do enjoy getting information from many different sources, I gotta say that this channel is the most enjoyable of them all to watch.

  I have never in my life been interested in engineering. I can't stop watching these videos.

  the owner of this video said tonight that she didn't take the place because of the garage

  The forensic investigation of this poster is amazing.   This building was clearly distressed months (years) before collapse.  Too many people ignored warning signals.

  Hi! I am an architect specialist in restoration of heritage buildings (from Romania) so in my career I saw a lot of damage to the structure of a building including water damage. In the video you analize almost all the concrete columns show a wet moisture line at their base, 10 - 15 cm above the floor. That usually indicates presence of water through capillarity. All those columns are soacked in water, the water insulation is non existent below the floor. If that water is salty the corrosion is incredible. So the water migrates also through the floor, evaporates and then condensates on the slab above further contributing to the moisture in it.

  I think a lot of us are gonna end up being amateur structural engineers after getting through with this series lol

  I'm just a mom/preschool teacher and I don't know why, but I find your videos fascinating! I didn't think I would ever care about structural integrity, who knew!!

  I have never seen a more balanced, understandable and earnest attempt at finding an assignable cause. Thanks for ALL that you are doing.

  I’ll never walk in an underground concrete slab parking garage the same way again. Thanks for sharing!

  Remember folks, when looking at an apartment don’t just look at the apartment itself, take a look at the structure as well

  Good analysis. &nbsp;I am a structural eng. who designed over 50 suspended apartment slabs, &nbsp;and would like to add my 5 cents worth. &nbsp;Looking at your presentation, I think what was a big component of the failure is the part you can&apos;t see, and that is cracking directly over the columns at the top of the slab, within the negative moment regions. &nbsp;Those cracks from the top of the slab were open to direct water infiltration causing water damage to the slab, which in turn decreased the punching shear resistance of the slab until failure. &nbsp;This was a plate slab, meaning the punching shear resistance of the slab was near it&apos;s limit from day one. &nbsp;Over the years, degradation of the concrete strength over the columns would open the possibility of catastrophic failure due to punching and game over. &nbsp;<br><br>I wouldn&apos;t be surprised if water infiltrated the slab via the top cracks located over the columns and migrated horizontally to the bottom cracks located at mid span. &nbsp;It would be interesting to obtain forensic info on the state of the slab over the other intact column locations by removing the tiles and exposing the structural slab to determine its integrity. <br><br>I wonder if they had automatic sprinklers within the planters, causing a continuous supply of water in addition to the annual 5&apos; of rainfall in Miami. &nbsp;<br><br>Wasn&apos;t aware about the debris field until the end of the video. &nbsp;Holy crap! Looks like the slab failed progressively in bending, slab integrity was significantly weakened until nearby column punches through catastrophically and the whole thing comes down. &nbsp;Wow!! &nbsp;Cheers from Canada and keep up the great work and analysis.

  Forget about how nice the units, lobby, outside perimeter like a pool are. Care about the the structural foundation of the unit you choose to buy or rent. Your very life depends upon you doing so. Get an engineer to give it a once over.
