Yes, that calendar was considering no major delays. The most likely reason for it to take longer is the winter of 2013-2014.

Went by the site with a real camera today and took a bunch of pics. Fortunately they were doing a lot of work and it was pretty interesting. They were lowering a rebar cage on the south side and trying to get it to fit over the vertical rebar beams.

When they were first lowering it. These are on the west side.

The rebard on this site is massive but it looks like the floor space will be comparatively small.

On the above note the blue horizontal bar - it is a bit hard to make out from the core. It is what the crane is holding up and in turn the support wires from it go down to the rebar.

The guy hanging on the side was bolting in the form.

Some very quick welding or cutting. I couldn't tell which it was.

Great update, by these pics it's easy to understand how big the windows will be compared to a person.

This project is really cool, I was just wishing that the top would not just be a flat area. IMO, this building would look better with some decoration on top.

Way to go NY!

I wonder if the facade will consist of precast forms that are fastened to this metal framing. It seems that there are holes to attach such forms.

Not sure I understand what you mean? What holes are you referring to?

I assume that the metal exterior here that the worker is bolting into place is just a form for concrete and it will be removed, correct?

Not sure that I see any other holes.

The holes are on the white framing at the bottom.

There are rivet holes on those metal pieces. I would have thought that concrete forms would be wooden -- not metal.

Understood. The holes seem to all be on the bent pieces - the inside wall seems to have no holes which means it could be a concrete form.

I've seen metal concrete forms before. For example they used them for the concrete at the base of WTC 1

Not certain that that is what they really are - that is just my uniformed guess. I'd love if others fill us in on the details of what we are looking at.

Once, looking at the camera, that has not much detail, I thought that those forms were made of precast concrete, that would serve as a form and as something as the facade cladding. A few days ago I realized I was wrong.

Those are metal forms, the holes are to fix them together. Metal forms are common, they are more durable than wooden ones, you can use them many times.

The facade will be not more than the exposed white concrete of the structure, as builder37 said

The form-work is therefore designed and built to accomplish this. The entire system of exterior forms was custom built for this project and made from stainless steel in order to achieve the architectural requirements - and to maintain the required cycle times.

The white metal framing has already been said to be the mold for the white concrete. So im sure we will get some more white outer concrete pours next week for the horizontal sections they where just installing the rebar for today.

Thanks for the clarification. In a few weeks, we'll see for ourselves when the forms move up.
