It seems that they are begining to do the transitional element in the 57th st. side. The resolution of the camera is not good enough to be sure, but I think it looks like a different arrangement of rebar, like the two central columns are being expanded to both sides. Or maybe being divided into three smaller columns.

Why didn't they just start out with 7 columns instead of switching from 4 to 7???

I think because four columns take less space in the basement floors.

Great pics, must be huge from the street.

Damn I missed that big lift again...I walked by at 8:30 and nothing much was happening.

the lower floors on the 57 st side of the tower are more open because this will be part of the retail space. the retail space extends into the north half of the tower up to the sixth floor and i am sure they wanted a more open contiginous space with adjoining retail building yet to be built.

seems like everything is in order. I was worried with this "stop work" order thing

But if it is the forms causing the banding, then perhaps the forms flex/bow outward (due to the weight of the concrete) ever so slightly between ribs, and that affects the thickness of the concrete just enough to affect the rate of curing?

it looks like they cause it, allthough I wouldn't know why. The ribs are a necessity to prevent the forms from flexing under the load of concrete.

I am an structural Engineer from Sweden. The pattern can be from the ribbs caused by difference in temperature. While concrete hardens its chemical reaction creates a lot of heat, especially with high strengt concrete. The steel form cool down the concrete and locally where there are ribbs the cooling is more sufficient. This difference in cooling might effect the curing which can explain the pattern... What do you think?

Footprint of SWFC = 4 times the footprint of 432 P.A.

And will be only 200 ft or so shorter,, that's remarkable.

From 426m to 492m the difference is roughly 200ft not 200m

And he meant the SWFC not Shanghai Tower

432 Park (1,398 ft) would be comparable to the Jin Mao Tower (1,381 ft) in height.

and...

Nordstrom Tower (1,550 ft) would be comparable to SWFC (1,614 ft). Short by only 64 ft.

I still don't think enough of this building (or any of it actually) is on Park Avenue. This should be a W57th or 56th Street address.

@kairaka If you mean the Franklin National Bank Building, it will be between 15 august and 15 september. Mark my words
