not just damaging the street that's the issue.

If the ground fails below the crane then you run the risk of the damaged crane and the "rescue" crane falling.


Given some of the horrific sink holes we’ve seen in that area I’m curious how stable the roads would be for projects like this. I guess you are spreading the weight substantially but it may be an extra layer of concern/research before rushing forward

I’m curious to know if the cranes are in free swing mode or if they are in a locked position. During wiind events the cranes are put in neutral and allowed to swing with the wind. If locked, it puts more pressure on the tower and foundation.

So what's the plan with the cranes/demo? Last I read is that they abandoned the plan to secure them with extra cranes. What else can be done? Or are they just going to let them fall? Anyway to protect the Saenger?

If that crane collapses, there is nothing you can quickly put up to protect the Saenger.

looking at the web pages for the architect and construction, they are pretty small outfits. I will guess that the bid package for the structural steel has a comment, "structure design by supplier". the documentation provided by the steel supplier has notes to the effect"drawing are generic for assembly use, loading design by owner".

quite possible there is no load design for the structure

Well since you know exactly what happened and how it happened and who's responsible, fill the rest of us in.

Good point. Who knows at this point? I don’t think the operators were thinking of protocol when they were getting out of that thing as quickly as possible. I still can’t imagine what was running through their heads as the building was collapsing around them.

Have there been any other videos put out from other angles? Surely there have to be some other cameras in the city that caught the collapse

What happens here when no entity involved in this actually has the assets to fix it? It’s sort of an interesting quandary we may have ourselves in with this debacle.

While sitting in traffic this morning on I-10, I got a good look at the site. The crane that is closest to Iberville has a noticeable lean. It's not massive and to my untrained eye, doesn't look like it's going to fall over soon... but it absolutely has a lean towards Iberville street.

I do wonder how the winds act in that area, considering the tall buildings along Canal to Poydras, and the shorter buildings from Canal into the quarter, will act on this building, which is right at the border of those two areas.

Maybe one of the OT weather experts can chime in.

I believe there are some large electrical duct banks that run under Canal St that are large enough to drive a truck through. I doubt it can support the weight.

On this build, I don't know. Going forward, maybe bond requirements need to be significantly raised to ensure someone / their insurer has enough capacity to handle "worst-case scenerio"? City doesn't issue permits until that is confirmed.

can fail in compression. It it just strong in compression. That's the f'c. Typical f'c used to be 3000psi but now is usually 4000-5000 psi. High strength goes into 10-12k and more.


Have we established that the slab works? From what I recall youre looking at 25' spans with 5.5" slab at f'c=4ksi...

Without doing the math I dont think this works on paper.

Builders Risk and Performance bond will likely cover most of this. Hell, the GL carriers will throw up a pretty decent sum of money if they can get a release and out of the litigation. These insurance companies know how expensive these types of litigation are. I can’t imagine there’s not enough insurance to cover the direct losses. The business interruption issues are going to be a whole different animal.

I'm not so sure about that.

I was talking to the owner of a company that had bid the buck hoist on that job and he was so glad they didn't get it. His takeaway was interesting.

1. Hard Rock will send a letter that they can't take over the property. This will start the snowball.

2. The bond will no longer be good so there will be no money there.

3. This will all fall on Citadel's liability policy and that is where everyone is going to get shafted. This will be considered a single occurrence accident and that is all the insurers are going to pay out. Anyone have a copy of Citadel's certificate of liability?

The city will end up having to foot the bill on most of this in the end.
