    Miami Beach, Champlain Towers South apartment building collapse, Part 08

    Unless you (the contractor) are not ready when the inspector/engineer arrives, or the work is incorrect and the inspector/ engineer has to come back again, or the concrete pump broke and the pour took 8 hours longer than planned, or the contractor can't read the plan and submits 87 RFI's about...

    There is also what is called structural observation in section 17 of the building code. These observations are performed by the engineer of record. Structural observation is just a periodic site visit. Example, just before pouring the first deck, the engineer comes out and takes a look at it...

    I can imagine the conversation. Buyer to engineering consultant: "So, do you think we can salvage the foundation to save money?"

    3DSoftwareDev, I can clearly see the beams. No squinting, enhancement or imagination required. It's the only location in the building this arrangement of beams occurs. Obviously from the picture you can't tell the condition of the columns.

    I find it odd that beams 33,34 and 35 appear to be exactly in place. They also appear completely intact. Does this mean the columns below (N8,O8, N9.1 and O9.1) did not fail?

    The slab steps are in the model but they appear as beams when the slab is omitted to show the framing. Only the vertical portion of the step is shown. (In the shots that reveal the framing.) I did notice the beam38's are missing from the east stairwell. It's very interesting that they show...

    Agreed, that construction joint looks bad. It looks to me like the top reinforcement was terminated at the joint. There are possibly bottom bars, which look they were laying on the form work and not chaired up. No dowels, construction joint was not roughened. I saw a picture of the lobby deck...

    Ungrouted CMU wall. I don't see any rebar. It wouldn't take much to blow that over.

    Looks like a construction joint. They made the key way but no dowels..... I saw some video of the south retaining wall that looked similar.

    I agree that the hired engineer has seen something to indicate a possible geotechnical issue. Especially since the recommendation was for buildings east of Collins Ave. Also the timing of the recommendation raises suspicion. If he was just being overly cautious, why not make the recommendation...

    If both of these prove to be true, it gives actual evidence to the falling penthouse balcony theory.

    Isn't the view of the TikTok video approximately one column line east of where the AC units and roofing materials would have fell? If your your theory is correct, I think the ac units would be more to the right in the TikTok video???
