The marathon concrete pour begins Saturday evening and is expected to last 20 hours without interruption. The attempt will be verified by an official from Guinness World Records.
About 2,000 truckloads of concrete will be driven throughout the weekend to the construction site in downtown LA where a skyscraper called the New Wilshire Grand will be built.
... For the past several months, crews have prepared the site by digging an 18-foot-deep pit and lining it with 7 million pounds of reinforcing steel. They will then add 84 million pounds of concrete.
Because the concrete must be poured within 90 minutes of being mixed, trucks must arrive on time. In case of freeway jams, alternate routes have been mapped.

Hell, yeah! Good luck, and let’s rock!
I just saw that o the news and thought oh boy time for some pretty bad mixs ad 40 more at the site
I sense that spmebody will be making a time lapse video of this extravaganza!
Thanks!
Misleading title Alert!!
The word "building" qualifier is sorely missing.
There are more than a few existing concrete arch dams worldwide which easily exceed this pour.
"What gives Davey, we pouring concrete today?"
they paved paradise and put up a parking lot
Might see a surge of Missing Persons....
Oh wait, it’s not Chicago
What about Hoover dam? Was that not considered continuous?
ah, but were they continuous?
Fast pours are catastrophes waiting to happen. I have seen formwork for walls buckle and bow multiple times by flowing in concrete faster than they were designed for... The pressure is greater as the aggregate is not locked together and the concrete behaves like a fluid. A very DENSE fluid.
The ties through the concrete snap and nothing is holding the inside and outside forms together. Rut roh!
Slow, even pours placing the concrete in lifts all along the structure while vibrating it with a donkey pecker as you go... that is the best route.
Good luck.
No it wasn't. The Hoover Dam was poured in multi ton block increments. Faster heat dissipation and quicker curing time.
I don't believe this current pour will set up in two weeks. Two months...maybe.
An 1,100 foot skyscraper in middle of earthquake country. What could go wrong?
How do they keep it from getting too hot?

I’ve heard that the Hoover Dam will continue to cure for another 45 years.
Precisely. Bump.
Right!
My first thought was, “What about Hoover Dam?!”
And parking for 60 vehicles.
Sounds like it will make for a good reef after the big one hits.
