Well, after a continued erection (of steel) it is better if they finish


Anyway, the steel erection continues, in a few hours, more columns were placed and one more on the way.

Looks like the core has taken 8 days for it to rise by one floor. I know that the western section for the podium does not exist anymore however it is a huge increase in pace.

Yes, core construction has increased significantly.

They poured the east section 2 days ago and they began jumping yesterday!

Nice to see the steel rise. These columns look so thin for a supertall building.

The beams for the tower portion is bigger than the podium section.

Yes, you can see the difference between the two columns in this picture.

I don't know much on the subject, but maybe the big ass core bears most of the podium's weight.

I would take a safe gander that that could have something to do with it. The core is impressive. I find it to be the most impressive part of the structure just as the fortified concrete base of One World is the most impressive part of that building. I mean, its stronger than the concrete in the Hoover Dam! Damn!

Podium is only 11 floors, while the columns on the periphery of the main tower go all the way up to 46 (south) and 62 (north).

In addition columns on the main tower are part of moment frame on the periphery which increases the load.
