    Miami Beach, Champlain Towers South apartment building collapse, Part 15

    If the deck collapse started at the wall on the southern end of the deck and then progressed northward toward the building, then why don’t we see the collapsed deck in the TikTok photos posted by Sym P. le above? These photos appear to show sprinkler pipes and drainage pipes that were hanging...

    Thank you, Optical98. Here is an unzoomed photo that you can zoom in on by scrolling in Windows 10:

    While we are asking for help in identifying objects, can anyone help me identify the object in the yellow box in the following photo?

    I was silent from August 21 until September 6, when you resurrected your ridicule of me by re-posting my own previous posts above. Why do you insist on abusing people instead of giving your own theories and defending them? Do you enjoy playing god instead of trying to come up with your own...

    Miami Beach, Champlain Towers South apartment building collapse, Part 12

    OK, guys, forget for a moment about how the objects might have gotten on the debris pile. The photo below shows the objects on the debris pile that happen to be found found at the same location as the objects in the TikTok video. Therefore, at least some of these objects should be the same...

    The rebar sticking up in the right hand square is from column 27, otherwise known as column M10. The pile was pushed from M11.1 toward the drive ramp before this photo was taken.

    SFCharlie, I agree with your cone dimensions. This was how I estimated the dimensions above, by comparing them to the cone dimensions.

    SFCharlie, Thank you for all your work above. I agree with the scale you show. But your green square doesn't agree with any of the objects that I have identified. The downward-pointing arrow to the left of your green square is what I have believed to be an AC condenser. And the arrow below...

    SFCharlie, the full video is titled "Recovery Efforts Continue at Surfside Collapse Site", and can be found at https://www.youtube.com/watch?v=jI6Up5Nv70c. The scene from which this photo was taken occurs at 4:45 into the 5:02 long video.

    It’s me again. But before you begin the ridicule again, please hear me out. The photo below shows the debris pile that was left at the end of the ramp for two days after everything else was removed. I believe that this was done because the Miami Dade recovery crew believed that the pile...

    Miami Beach, Champlain Towers South apartment building collapse, Part 11

    Just found two more security cameras on the pool deck. Unlike the two cameras found by Kreemerz in Part 2, which appeared to look south directly over the pool area and east to see people approaching the gate to the pool area, these two cameras appear to look south over the pool deck between the...

    Miami Beach, Champlain Towers South apartment building collapse, Part 10

    After reading the Miami Herald article “Surfside tower was flawed from day one” found by SFCharlie, it sure sounds like the CTS building was poorly designed and poorly constructed and was ready to collapse at any moment. But the article does hedge a bit, stating that “Although the trigger is...

    Below is a close-up of the CTS roof taken on 6/22/21 obtained by zooming in on the aerial photo supplied by Santos81. The brightness has been enhanced to provide greater contrast, but nothing else has been changed. With the brightness enhanced, by comparing the photo to another photo taken...

    Santos81 asked: Good point. I don't know how these light sources might change the relative brightness of the building features. But one can clearly see in the CCTV photo that the illumination is higher on the left-hand side of the building than on the right-hand side, implying that reflected...

    The first photo below shows the first frame of the surveillance camera video. On the extreme left-hand corner of the Champlain Tower building we can see that both windows and parapets appear to be dark while the undersides (i.e., ceilings) of the balconies appear to be light. This is because...

    Miami Beach, Champlain Towers South apartment building collapse, Part 09

    253RWD, thank you for the photo showing the door to the middle roof above. Fortunately, I had agreed earlier with Santosi81 and Murph_9000 that a door was there. Now, if you look closely at the photo you may see something interesting that you, Murph_9000, and Demented (who also posted the same...

    Santosi81 and Murph 9000, I agree with you. I was misled by the overhang of the elevator room.
