A continuation of our discussion of this failure. Best to read the other threads first to avoid rehashing things already discussed.

This video is interesting too.. a walk through including the garage that someone did of the building in 2020 -

They don't show the exact columns that are suspected to have failed, but they all look like they're in good shape. All of the columns that punched through are in it. She does seem to show some exposed rebar in the garage, but it's under the portion that didn't collapse.

I saw at least one security camera in the garage from that video.

New 2020 Garage video shows area under the pool deck/parking area that collapsed.
Start @ 4:40 and walk-through continues to the exit ramp.

@ 4:07 they view some ceiling crack repairs under the portion of the building that remained standing. (near Parking spots 55 & 66)

Jbourne.

The Columns highlighted Js1580 post are visible in the video @ 4:50 to 4:53.

The slab (garage ceiling) looks a mess of painted over, patched up ("repaired" cracks, and are those Stalactites on the underside?? Possibly underneath de-laminated paint, or what.

there's also standing water everywhere.

 

[GPR_Tech]

They are likely unremoved epoxy injection ports and not stalactites.

JimmyP80 - Sure.. but if someone told you that this building was being condemned during this video because it was going to collapse in the next year, wouldn't you still ask what would cause that? I live in Seattle, and I didn't see anything in there that I haven't seen in many apartment buildings here.. and worse. None of them suddenly collapsed though. A little standing water in garages is pretty normal really.. the cars bring it in when it rains. It was built to withstand hurricanes that can completely flood the building too.

It's sort of interesting that only about half of the garage ceiling has that problem too, most of it seems to be in perfect shape. Near the entrance it doesn't end where the building starts upstairs, but about halfway between the columns instead.

The column on the left in that pic is the one from the tiktok video, and the one on the right is the pillar that seems to be collapsed in the video.

Js5180, in your patio deck picture with orange column marked, I think I see two more columns I circled in green. Where are these columns in relation to the the column line your marked from tik tok video?

 

[gonefishing2]

Also notice the bottom right hand corner marked in picture that punched thru on other end of planter

I cannot imagine the slump for any sort of corrosion resistance... don't even use this for ICF walls...

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

Thanks GPR_Tech, it all makes sense now!

Video below shows good views of garage on walkthrough - 9 min in to 12+ min in:

This is the Champlain Towers North walkthrough, and has been posted (not to mention translated) before.

 

[GPR_Tech]

NOTE that is a video of the NORTH tower and not of the SOUTH tower. (South is the one that collapsed)

As predicted, there is now political pushback to the proposal to inspect all older condos in Florida. In another month the whole event will be part of forgotten history.

Great find, DavPC! I wonder who had this video on hand all these years, perhaps a TV news archive?

Makes you wonder how the repair work was done, as you noted.

9 inch slump? Really? Unbelievable! Seems that the cement company had a hard time even making it. Actual was only 8,5". Ran out of water on batch 9/9?

 

[gonefishing2]

The screen shot from GPR_Tech's 2020 walk thru shows the beam that connects the perimeter of the building at column line L, and this beam tie for perimeter of the East side of the building exists starting with K column line thru M as well as 3 more column lines.

Seems like this strong tie between building perimeter and patio deck would tug even harder on the building once the patio end collapsed? Tug harder than if just flat slab in that area.

and they added water on site?

Column Line I does not have this beam tie to patio deck
