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

By fluid I guess it means suspended on liquid.

Here is the image of liquid rust I had in mind:

It is possible to see the liquid dripping from the PVC drain in this excellent video by our friend Jeff:

That photo begs so many questions. I believe that is a catch bucket under a leaky elbow fitting that has been doped up with no success. Where do you start with that? Is this pvc drain like the one elsewhere that simply drains onto the floor at a column? Then the problem here would be the water is just running onto the floor at the non-preferred spot. And is that a junction box that the water is running onto? And is that covered with pitch to keep the water out. What the hell is going on there? Is the rust primarily from the junction box? Not that it is not a problem. Is this the standard for maintaining this building? Maybe I am seeing things.

Edit: Someone watched one too many flex seal commercials. Anyway sealing threaded pvc fittings is not always as simple as it should be. Too much tape and they crack. Where is the documentation that shows these drain pipes were ordered to be installed to drain onto the floor. And how did they decide where they should go? Or did Joe the plumber do it under cover of darkness?

One more thing in the picture that I wanted to point out in that picture. Some sort of concrete chunk left clinging to the wall by a thread. So the slab cracked apart there after mostly pulling out of the wall and pivoted down.

Agreed, it is disturbing. That is/was a junction box. If you watch the video you will see there is a bucket below to catch the runoff.

clinging to the wall by a thread

It seems to be resting on something that is jutting out of the wall. It could be an illusion. Just what it looks like. Is that a drain for the planter? Is there a hole in the wall there after the site is cleared?

After more looking and comparing I think what see jutting from the wall is circled below in a different view. And what you see as the slab is a diagonal crack going up the wall. And it looks like the wall is partially collapsed here. Well that would be something.

Thanks Reverse_Bias,
There was a conduit that ran along the wall feeding the light on the corner of the 8-foot wall and possibly also the water cooler at the corner of the pool deck. I'm sure that is what that diagonal line is.

a different view

Thanks zebraso
I see the lump sticking out, that appears to align with the hole in the CMU wall above. Looking at that 7 news image.

Is there a hole in the wall there after the site is cleared

The wall was also cleared.

 

[zebraso]

Is it fair to say this is what we are talking about? (in my faint red circle)

I think the area circled is further west than the hole in the wall. The location of the hole in the wall was just west of the single cone where the hoses (since MWI supplies industrial pumps) run down the wall.

I had to enhance your image to see it, but I think it's there.

further west than the hole in the wall

Thanks, I was thinking that was a possibility. The perspective is pretty tough. Not sure. I agree it looks far away. It looks like it's halfway to the end of the wall but I can't quite say for sure if that's right, because the farther things probably appear not as far as they really are. I think that's correct as to the perspective. It's a bad angle.

 

[zebraso]

I have a feeling I am about to see all kinds of things. So I better stop. But I will just note that I did not really notice part of the planter wall is resting on the truck. I have a tough time seeing that diagonal line as conduit in your enhancement. But the boundary wall looks deformed to me. That just does not look very planar. And I don't mean like in those photos of units where is was claimed the floors were sagging when it was probably the lens.

 

[spsalso]

"Liquid rust"?

Maybe. Maybe not.

I see a LOT of brown goo on top of what looks like a small transformer (not a junction box). I don't see evidence of how it got there from above. Nor do I see how it could have been generated by the POSSIBLE transformer inside.

Please stop "reaching", and come of with real evidence!

It looks a little too much like ballast tar. But that's crazy too. I'll go with brown goop on that one.

I might be over enhancing contrast so maybe it's just a dark spot on the wall. Don't think it would be that important to the collapse anyway

Good spot, that pic shows down into the hole much better.

just a dark spot on the wall

That post demo damage is farther to the west too. I had to find a photo back about 6 threads ago. It more than 2 cmu faux columns down from the still standing wall. So there is no deformation in the area of interest that would suggest a wall collapse. On a positive note there appears to be no tar buggy in that hole either.

 

[IanCA]

I don't see evidence of how it got there from above.

If you watch the video you can see the liquid dripping from the PVC pipe.

Nor do I see how it could have been generated by the POSSIBLE transformer inside.

I'm pretty sure it was a chemical reaction between the salty water and the carbon steel box.

Please stop "reaching", and come of with real evidence!

FeCl2 + H2O -> FeO + 2HCl

 

[zebraso]

I'm pretty sure it was a chemical reaction between the salty water and the carbon steel box.

If I leave a coffee can beside the kitchen sink for too long I get a rust ring. Salt not needed. I mean the water is dripping on the steel box and the flanges at the bottom are partially dissolved. It would be a miracle if there were no rust stains wherever that water drips and runs.

It is most likely a transformer deferring to electrical. Transformer boxes can have cooling vent holes in the top. So they might have covered those holes to keep the dripping water from entering. Did they use a brown garbage can lid? Maybe. That's code right?
And the stains on the white bucket are reddish brown.

Edit: closer look at video and it look like a rectangular enclosure that may have ventilation holes under a drip edge. The spots with water running down may be bridges created by iron oxide deposits to the drip edge. (Lot of conjecture). Probably designed for damp environments. NEC?
