Seven million pounds of rebar.

Not exactly a record footing. When I was in college in El Paso in the 60's, ASARCO built a 828' tall stack for the refinery. The footing was 37,000CY. Given the technology and availability of concrete, it took 4 weeks to pour.

They then did a continuous slip form pour of the stack which was a double wall design. That took almost a full year of continuous pour.

They demoed it last year by dropping it whole. Made one heck of a "thump"!

Wasn't Hoover Dam a continuous pour? I read that they poured sections looking like stepping stones, or a three-dimensional checkerboard, but they were pouring around the clock I thought.

I'm sure that there are plenty of structures that were large continuous pours, but I think they were only considering footings.

My first full time regular job was working as a concrete inspector for the Louisiana Highway dept. in 1965. They were building the Paris Road Bridge over the new man made Mississippi River Gulf Outlet. When we poured the foundation for the piers that sat in the Outlet, we had one concrete plant dedicated to just that job with 20 trucks rolling continuously and we worked 30 hours straight to finish the pour. I don't remember how many yards it was but it was huge.

Now they have blockaded off the Gulf Outlet after it was proven that it caused the main flooding in New Orleans after Katrina. Oh well, one more multi-billion dollar boondoggle.

There must be something peculiar about this building/foundation that would not permit any cold joints...
...most solid pour foundations are in compression most of the time...?

How smart is an 1100' tall building in an earthquake area? I have seen how the put the buildings on springs and rollers, etc., but I wouldn't want to be in that building in strong quake.

California has earthquake design standards and a commercial building will have to actually be engineered, so my guess is that this building will be standing after an earthquake that will destroy a lot of older 2 story buildings.

Records only count if they're recorded! :laughing:
According to several news articles, the previous official record was 21,000 yards in 1999. The new record was just 200 yards over that, at 21,200.
