Oh man, are they going to build scaffolding to rest the forms on for all 89 floors? Seems like a pain to me.

Take into account that what you see on the cam is just the base of the tower.
The lower floors will be build later filling much more of the site.

Nah, just on the first floor I think. They have to protect workers from stuff which could fell down. Plus, they have to put wood around those concrete columns since they will carry a lot of huge stuff in and out, they sure don't want to take off those perfect corners.

(22.86 is 93.5 feet and half of 1wtc and about the same as the upper parts of the woolworth building.)

I think this building it's like a big breakable white cookie.
So beautiful.

There is indeed a great resemblance to a cookie.
btw they are working late today, even now another form is going in on the west side.

Each side is 93.5 feet, and with a height of 1,398 feet, the ratio is 14.95:1 , which is still extremely thin. I know that previous estimates posted here stated 16:1 and 19:1, but that's now known to be incorrect.

28.5m per side is wider than I thought.

A few months ago, we were discussing its square footage, and guessed each side was around 95 feet, and someone confirmed 93.5 to be the official number.

Never realized they did that instead of those forms. Thatīs how they do it here since I remember paying attention to buildings constructions when I was a kid. And they wouldnīt have forms for specified constructions...they are the same and adjustable.

@ LAF2 Well ok then. But I remain hopeful the height will increase.

A question: Anyone why we see the forms on the 56th street side but not on the 57th street side?

I think it is because, since they are only four, the columns must be bigger, so the standarized forms wont work there, hence, they use ordinary formwork. Besides the 56th st. side is the actual facade, the 57th st. side, on the lower levels, won't be the facade, It would be hidden behind the retail base, so it won't need this formwork, use to give the facade a smoother finishing. (and I guess it is standard gray concrete in the 57th st. columns, as in the core)
But we certainly see the formwork when they pass from four to seven columns.

They are still just in the initial stages in setting up the system for how the perimeter will rise. You can see this on the 56 street side. Once this system is fully up and running things will progress much faster. There are always a few bugs to work out. The perimeter form system will not be fully in place until the tower rises above the retail floors and the 57st tower facade forms are in place. I am certain that the overhanging scaffold you can see on the 56 st side now will then completely encircle the tower and will rise with each floor much like the core.

If you don't watch this construction site like a hawk, you will miss action. I have noticed, that an opening has been created on the forecourt, presumably for the Alimak material hoist that will climb alongside the tower as it rises. I certainly wish I saw the opening being created.

Every day, an action-packed day at 432 Park Avenue.

Looking back at the screenshots I have taken, I saw that the area where the opening occurs, when the slab was being formed, that area was boxed out, and the slab poured around it. No concrete was poured in that area. It was then just a matter of cutting the wood forming below to create the opening. Going back to the foundation screenshots, that area occurred as a recessed slab on the bottom-most floor slab.

it just occurred to me, that the penthouse is going to be the same size as the floor visible/under construction right now, which you can compare to the surrounding buildings :o

even a half-floor apartment is going to be massive
