Thank you, I think I've called them everything from look-outs, to flying bridges, to flying stairways. I would have never guessed Diving Boards.

Looks like a crane might be going up inside the steel structure at the north eastern corner of 3WTC. The strange red steel is going up there, for what I think might be a custom built crane pad. But I don't know if it'll be for one of the 1280, or for a new crane at 3WTC. I could also be totally wrong and it'll have nothing to do with a crane, but it's worth mentioning.

I'd also say it's for the 1280, only because of the size of those white and red mast's that have been sitting there

Diving Boards, hmmm.... I hope nobody gets any ideas

As far as the possible crane pad at T3, I was wondering about that. If it's for T3 why would they put it on a corner instead of in the middle, and why can't the existing one be used for the steel too? And if it's for the hub it will need an awful lot of reach to get at the North side steel.

The first piece of that just showed up.

Last night they finally shifted the northbound lanes to the west, so that they can destroy the last temporary bridge and continue restoring West Street.
Lots of concrete pours happening there in the last time for the foundations of the future road, probably some more layers will follow..

[QUOTE=Beber;96053364]

<skip>

And about those 120' pieces, I'm really skeptical. I don't think there's any structural need for those ribs to come in only one piece. As someone said, they really don't need to support much weight other than theirs, so they could just assemble them on site. That's also why I'm surprised to see 50 tons pieces. I mean, that's almost as most as 1WTC's jumbo beams, and they really don't fit the same purpose. And I'm still wondering which pieces are 27' wide.

<skip>

Have you considered that some pieces of the central arch could be quite long and very massive? Even though it will be supported by the lower sections of the ribs, the central arch will cover a 300+ foot span.

Went over to the site today. I'd defiantly say this is for the M1280









Looks like these hydraulic lines on the right side are for it to jack up on the rail that is there

based on the fact that this is falcon's climbing rig, i would say that this is for tower 3.

I think that the calatrava steel belongs to skanska-koch.

The geometry of the building demands 3 cranes. (with the erector borrowing the concrete crane probably one day a week to erect the south face of the building).

This is problem that you run into with a core first construction. The core creates an obstruction for the steel erection.


pics are awesome tho, definitely a brand new custom basket for this weird corner.

Seems like it's safe to say it's another TG 2300 (?)

Thanks for the pics! I think thejacko5 is right here, it's most likely to be a crane for tower 3.

Man, those 1280s are driving us crazy.

maybe. falcon carries their own 1900's. I am not sure how many they have, but I know two are at Fordham University in midtown.

We will soon find out, doesn't seem like there are any more parts of it there so I assume they will bring more in soon

Seems like overkill to be adding a third crane (a climbing one at that) for tower 3 if they are only building the stump. Maybe it's a sign that they plan for the tower to continue rising all the way to the top without going on hold. Then again, they removed the forms inside of the core.

Any chance this new crane would be used for both tower 3 and the hub, or that it would erect one of the 1280s for the hub? We've seen cranes in one site help out with an adjacent site before, to some extent.

I dont think they have an option in order to complete the podium, regardless of whether they are going to continue erecting the building.

It would also be unlikely that they would use a crane from this building to help out on the hub. despite the fact that its right next door, they really have to be treated as if they are on separate sites.

Looks like they made a ramp with the dirt they brought in near the old crane pad

i am wondering how they are planning to pour the diving board areas. There are clearly shear studs all over those horizontal members but i do not see any shelf angles for decking like we did in the other areas. (the deck that was used is bridge deck, it usually sits below the top flange of the main members and it is tapered at the ends to make installation easier).

I guess it will all be formed out, but gee, what a pain.
