Kind of a dirty work site. How hard is it to pick up a broom and sweep those steps, jeez?

That Jersey City website said those steps are the 'grand staircase' to One World Trade Center....all of my NJ suspicions confirmed.

That's an amazing picture and we can see just how huge this thing will look when it's done. We can also see why the lower portal pieces at the ends are different than the rest of them, they connect to beams already in place under the semicircular "balcony". Once they are done it probably won't be noticeable after they finish welding and painting them.

I hope they leave as much of that steel as possible exposed, it will look awesome!

BTW I think a while back there was a render posted from almost that exact spot. It would be interesting to compare to the real thing.

Is the transit Hub going to look like that pure white we see in the renderings or will it look like a steel silvery color?

The Transit hub has reached above street level!

We're going vertical!

You can see several pieces on the lower part of the webcam.

Portal Rib Construction

Does anyone have any details on the internal construction of the individual portal ribs (assuming they're not solid)?

They don't look like much yet... But it's finally above ground anyway.

I noticed this morning that the portal ribs in place (at least the three on the north side) have guy wires attached for support. I'm curious about the construction sequence - will they start attaching the arch segments as more ribs are put in place, building outwards from the entrance structures, or will all of the ribs go in before working on the arches?

No, there's a sequence involved.

First, 8 upper portal frames get bolted and guyed to their respective place,4 north and 4 south, following an outward-in installation. Each of them get guyed and temporary bracing is held between north and south (on skylight opening).

Then, 8 transition segments (4 north and 4 south) will arrive, each piece has its respective arch piece that will connect the portal frame to an adjacent one.

Bolting and welding begins, load is transfer to abutments and guy wires get removed.

Repeat.

Thanks for the information - much appreciated!

A total of 8 ribs have been installed at the east end (4 north, 4 south). It looks like they've installed some temporary bracing between them - possibly to help with alignment pending installation of the transition segments and rib segments?

Fascinated by the large number of unique pieces of steel that will go into this project. I'm guessing that other than possibly the ends, no two pieces of the above ground steel will be alike, unless the north and south counterparts might be mirror images of each other....

I pondered this. I think that because of the ribs being different lengths on either side, even portals that look identical from the outside are probably structured differently internally.
