Hard Rock Hotel construction site collapse in New Orleans

[RBHeadge PE]

City inspection logs showed Treadaway gave contractors at the Hard Rock site the approval to pour slab on the 14th floor. Instead, GPS data from the city vehicle showed on that July day, Treadaway made a morning stop in Treme, then went to the Westbank, stopping at the University of Holy Cross, his home in Gretna and an Ochsner Clinic -- but not near the Hard Rock Hotel site.

I've heard this story before.

tl;dr The L&I inspector did the same thing. He killed himself out of guilt.

Thanks for sharing.
For whatever it's worth the city councilwoman, Kristen Palmer, who they talked about at the beginning of this video lost her recent election campaign.

They used W6x20 columns on the top floors? WTF were they thinking?? I have never seen something so small in a multi-story building.

Heck, we very rarely use a W6 for anything. Too hard to get a connection on one.

The engineer that signed off on this is facing a major legal battle, I know I could never get my calcs to pencil out on something that small for that type of load even when ignoring wind/seismic!

I’ve never seen a W6 used ever! Smallest we’ll go is a W8, for connections like mentioned above.

I've used W6 in the past for a short elevated walkway brace and in numerous pipe supports.

As for using them as part of the primary structural system, never.

We use W6 for spacers on a very rare occasion. But that is about it. If I am using a 6" anything it is usually a tube.

I really appreciate the "nothing lined up and the beams were too short so we just slugged weld metal in there to fill the gaps instead" approach.
