Hi, Dino --I saw three columns installed just north of the east end crane, but am having a hard time figuring out what they are.

Aren't they a bit close to the center line of the building to be rib bases?

Or, are you referring to the steel work along the north wall?

No no, I meant those 3 columns at the crane..They're part of the main structure which will rise there..The show just begun..

That's what I thought at first glance until I went back and looked where I had done this on Jan 19th (rain/fog is obscuring the current view):

When you look at the KPI webcams you can see that the first three columns of calatrave arches are placed and more are following soon. Please can someone update something about the situation that is going right with the project?

Here's a pic from the webcam that shows the rib bases connected to the surrounding steel:

I think they snuck in a fourth rib base, too. Things are moving!

Steelwork is going on pretty quickly, and seeing what just arrived on site, it's going to get more interesting. You'll notice the two (one?) big pieces under the mobile crane hook, that just got delivered.

I seen them last night, pretty big. That is a 625 ton crane so they must be atleast 50-90 tons.

Looking at the webcams today I see a lot of new steel that has arrived - excited to see it go up! Also, a large concrete pour today.

Four new Calatrava columns already erected, plus at least two more waiting on site.

And a red crane (?) part was also delivered.
Question for the crane experts, could it be inserted in one of the two existing cranes or does it look like they erect a new one?

That is a jacking system for the tower cranes, It is most likely to be used on the tower crane closest to Church st. because when the crane swings, he will hit the steel due to its height (steel). I am pretty sure that you would have to take apart the crane to add the jacking system.

am i the only one who cannot see any of the Calatrava arch/ribs in these overhead pictures? I can't make any sense of what I am looking at... it just looks like a jumble of steel bits and pieces.. can anyone annotate the pics to highlight where the progress is happening? Thanks!

Look closest to the crane's tower, there are vertical pieces that appear a different color (off-white instead of rust). They aren't the arches yet - just the beginning. If you look at some of the renderings you can get a sense for where they may be - inside of the hub.

Thanks for the link!

So you mean the tower crane of Tower 3? Any info which crane they use for the huge steel pieces of the hub? Some time ago there were rumors that maybe the 18000 will be used again in a later stage of the project..

[Swiddle]

Massive concrete pour going on now for most of the remainder of the B3 level. According to the KPI TV cam, they started sometime before 1:45 AM NYC time. I don't think I've ever seen them start so early for a pour for the hub.
