NEW ORLEANS -- Several construction workers had to run to safety on Saturday morning as a large portion of the Hard Rock Hotel, which has been under construction for the last several months, came crashing down suddenly.

It was not immediately clear what caused the collapse or if anyone was injured.

Eyewitness video provided to WWL-TV shows the moment collapse began.

Upper floors began to fall on top of each other before the Basin Street side of the building fell to the ground below.

3. Oops!!

Somebody forgot to put Bolt A into Slot B.

Hope everyone is ok.

4. Looks as though it's

still under construction?

5. It is, per the article n/t

6. Video of the collapse.

Unbelievable.

EDIT: Used "share" link instead. There was something wrong with the old link. Thanks to Dennis Donovan for the tip.

8. Thank you!

9. YT changes the link if you've watched any part of the video...

...and inserts a time stamp. To override it, click on the "Share" arrow below the video and copy that link (make sure the "Start at" checkbox isn't checked).

10. scary

16. 👀 damn

[Hotler]

11. Hurry, hurry, hurry, over budget, behind schedule,

working from permit or bid set construction drawings instead of "For Construction" drawings. Post tension slabs suck, structural steel doesn't fall like that.

[Mike 03]

14. Was wondering about the cause.

It's bad enough when old buildings collapse, but it's hard for lay people like myself to understand why brand new or under-construction buildings do. "Post tension slabs"--does this mean the collapse was at the foundation level?

[Hotler]

15. Post tension slabs have cable tendons that ...

run all the way thru the slab from edge to edge in a grid like pattern similar to reinforcing steel (rebar). The slab is supported from below with jacks and wood forms. The slab is poured and after 3-4days of the concrete curing, the tendons are pulled tight and the support removed.

They may have removed supports to early before the concrete cured or, the concrete mix might have been bad.

You never want to see construction mishaps. I'm sure OSHA is onsite by now.

18. Sort of like tightening a bed sheet?

Makes it more firm and strong eh. My cheap analogy. That's interesting.

22. What is the advantage of using cable tendons rather than rebar?

nt

[Hotler]

24. I'm not an engineer. I'm in the structural steel side of construction. My guess is....

the hydraulic units they use can put some serious hurt (tension) on the tendons, a lot more than the rebar could take. It may be a cost thing also, cable tendons every eight feet vs. rebar every three feet.

[ornotna]

12. Well that sucks

I hope there weren't too many construction workers on site.

[Aristus]

13. Let me guess:

Non-union labor?

Is Louisiana a 'right-to-produce-shoddy-work' state?

[Cirque du So-What]

21. My first thought

Trade union workers serve an apprenticeship, including classroom and on-the-job training that far surpasses standards for jackleg contractors.

17. One dead, 18 taken to hospitals, 3 unaccounted for.

[Iggo]

19. Not funny anymore.

Thanks for the update.

[Demovictory9]

20. omg. thanks for the update.
