I think this was used as a temporary support for the flying stairs, I don't think they put up yet another tower crane, Otie wrote some time ago that a crawler will be used to erect the wings of the hub.

From Olympic Lad: "On the webcam currently, I can see what appears to be a completely new kind of piece of steel, which we haven't seen kicking around the site before. Exciting times!"

Looks like some round steel pieces that might fit into the holes at each end.

But with all the fog there today, it's hard to tell.

That's what I reckoned too. From looking at various renders etc, it looks as though there may be a circular lift shaft in those areas, so could be for that?

This is getting quite detailed

PS. More abutment pieces arrived to Port Redhook, steel deliveries being coordinated at meetings with NYC departments.
Wow that's perfect! I hope they do hold public events at the oculus plaza it would kinda be like what they used to do at the original plaza=]

part of the reason for the tent is for protection from direct weather like rain, the other part is because they are probably doing gas shielded arc welding.

argon is used to shield the weld wire from impurities in the air. so when the welder strikes and arc, argon is released from the tip where the weld wire feeds from , creating a mini atmosphere.

Yes, white mast sections were temporary supports for the diving boards, but now that welding is complete and load completely transfered, they weren't useful anymore. They are also removing all kind of temporary supports just below the Subway box, the grand staircase that connects PATH hall with Transit Hall is also taking shape, with rebar almost complete.

Logistic plans are still being reviewed and coordinated between the two major contractors of upper Oculus (Skanska Koch for steel erection and Enclos Corp for skylight). Current plan is to erect everything of Oculus (including upper portals, transitions, arch and rafters) using the Skanska cranes and the crawler will be used only by Enclos to assist on skylight.

Just looking on the street view cam and 3WTC cam, appears there have been a few dozen white sections delivered, currently on a flatbed, any idea if these are Upper Portal sections? I'm unfamiliar with how they should look on delivery!

Hmm, can't really tell. The cylindrical shaped steel is definitively for abutment elevators.

The first of the cylindrical pieces for the elevators is being installed currently!

Great to see that other areas of the hub besides the portals are under construction.
Six portals left by the way!

Now that I've evaluated with more detail the stepped terraces at the HUB-Tower 3 area, it looks like it suffered several redesigns as well:

The original Calatrava/Peter Walker design proposed several planters in a curved line that would oppose the Oculus outline. The paving would be uniform and completely smooth.

Since then, the arrangement has changed. The 2010 drawings show two different designs: the first one depicts straight planters with stepped terraces between them and T3, all 9 trees would be placed within the planters; and the alternate design does not show any planters but only a couple of stone seats and trees planted in a very similar way like the Memorial.

Now that I check with more detail the Earthcam view, I can clearly see they opted for the alternate design, no planters after all

Oh, I was told white marble is still being reviewed for the transit hall, tile dimension is being discussed wether it will be 24x24ft or 12x12ft.

From WTCProgress,


"The shape of the WTC Transportation Hub Oculus can been seen from high above the WTC site."

Yup, we will never see the beautiful planters that were proposed

8 trees after all, Gleditsia Triacanthos specie

Is that going to be the finished tile layout for the square in Otie's picture? I really like the gradual fade effect around the Oculus.

Do you have the tile dimensions right?

Would that be inches? 24x24 in (2ft x 2ft) or 12x12 in (1ft x 1ft)
I agree the curved planters and tree planting would have been a better transition from a squared building to the curved oculus. I assume the steel understructure for the trees would have been much more expensive.
