LOS ANGELES (CBSLA.com) — Developers made history Sunday at the site of the former Wilshire Grand hotel in downtown Los Angeles.
Adjudicator for the Guinness Book of World Records Michael Empric announced just after 11:30 a.m. that workers had broken the world record for the longest continuous pour.
The Wilshire Grand has a largest pour of 21,200 cubic yard, which is a new Guinness World Records title,” Empric said.
The Associated Press reports that the concrete pour of 82 million pounds of concrete lasted over 18 hours. The concrete was poured into a massive pit in order to build the foundation for the much-anticipated, 73-story tower.
“It’s a symbol of a Los Angeles that’s coming back,” Los Angeles Mayor Eric Garcetti said Saturday. “It’s putting the recession in the rear-view mirror, creating jobs.”
Along with breaking the world record, planners had also expected to save funds due to the consecutive pouring as opposed to taking breaks in between.
The $1 billion project includes office space, restaurants, retail, and 900 hotel rooms.
The hotel is scheduled to open in 2017.
Hoover dam was bigger, and it was continuous.
How would it feel to be that high during an earthquake?
Hoover dam was a lot of separate pours. They allowed the concrete to dry before pouring the next level.
The vibrators had the biggest and hardest job
Now ... if they were going to pour 73 stories of WALL ... now THERE'S a Guiness World Book of Record !!
OOPS ... write (pun intended) in front of my eyes ... 21,200 yds
A whole lotta shakin’ goin’ on.
“Hoover dam was a lot of separate pours.”
They had to keep stopping to fish bodies out:-)
“They had to keep stopping to fish bodies out:-)”
I’m not certain that they actually did fish the bodies out.
As I recall reading about the building of the dam, they became part of the foundation.
That’s a lot of kickbacks.

73 floors? In LA? Doesn’t seem wise.

I’ve seen that hole at 7th and Fig here in downtown L.A (the better part of DT LA). Didn’t dawn on me that construction for the building required that much amount but I think the building is just to top the opposite building across it.
ping
1,177 yards per hour.
118 trucks an hour.
looks like they have 11 boom pumps.
107 cy per pump per hour.
that's dumping some concrete.
if they were pouring a 4" thick driveway that would be 1,696,000 SF.
73 stories in one of the most seismically active places in America??
Kinda scary, if you ask me.
It was always my understanding that if you pour too much concrete at once the heat would make it take forever to set. I read the reason they poured the Hoover Dam in sections is that if they had poured it all at once it would still be curing today. I imagine concrete has gotten better in the last 80 years but I would think the general principle woudl still be the same
That’s what I was wondering. Certainly the dam couldn’t have been continuous from bottom to top, could it? How would the bottom of the forms withstood the concreto-static pressure till it cured? I’d have assumed they’d pour it like a layer cake in maybe 20-foot layers. Even if it wasn’t, I could still see single pours bigger than this one. But how would Guinness have missed such an obvious one? And what about 3-gorges dam in China? That one’s immense.
A body would a been a problem with structural integrity.
