Watching the construction of the transport hub is quite exciting but it's so bloody confusing! Super columns? Box girders? I'd love to understand better what I'm seeing.

Where are all of you getting your knowledge from?

great pics!

Here is the pic I promised, it's from the construction sequence drawings so it's thin on detail. (Less for me to edit.)

The super columns are clearly shown. The bottom chord of the truss is a plate girder, the rest of the truss is box beams.

All that temprary steel that can be seen on the earth cam is there to support this thing as it's being built. The same thing, but longer is going in on the west side of the #1 subway box.

This is a 200 foot long railroad bridge plain and simple. What makes it special is it's location.

Much of it comes from me. I have 30 years of construction experience and a full set of drawings. But, the drawings are classified information, so I have to watch what I post on line.

From the broadsheetdaily.com,

"W.T.C. Transportation Hub
D.C.M. continues working on welding and decking on the PATH Hall roof. Erection of the East Side Shoring platform continues. Welding of the East Box Girder is also moving forward. Another hammerhead column on the B platform was erected this week. Framing at the south end of Track 1 was tied into the newly poured sections of the D15 wall. Welding on the two super columns on site continues.
Infrastructure & Project Development
In the Central Chiller Plant this week, the welding for the 1,000 ton chiller piping continued, installation of control wiring and sprinklers moved forward, and high pot testing was conducted. At the river water pump house, two of the refurbished sluice gates were delivered and rigged into place. The sluice gate actuator motors were set into place and installation of control wiring began. The 4160 cable pull from the pump house to the main plant began this week.
· Streets, Utilities and Related Infrastructure
Drawings for Phase II 100% final design Package 1 have been signed. Final preparation and compilation of the documents is underway to be ready for distribution. Design and construction coordination of the streets & sidewalks for the subsequent Phase II packages continues. Con-Ed is progressing with the steam main installation at Liberty St & Greenwich St. Coordination of the sewer work on South Greenwich between Liberty and Cedar with ECS, Con-Ed and Logistics continues. Construction coordination of the Greenwich and Liberty Street utilities with other programs for Phase I continue."

Zen, thanks for the pic of the diagram. That's much clearer than the one I was looking at. Dino, great pictures from vickisando. The closeup ones really give you a better idea of how huge and complicated the site is.

It looks as though they may have run into a snag with the center spine. Today they removed the temporary support that they had placed next to the west wall a couple weeks ago.

There is word that the first piece or pieces of the truss are arriving on-site in about 10 1/2 hours.

It's my opinion that they will need further assembly on-site before they are actually erected.

Now they're putting that temporary support back in place. On the temporary platform is, I believe, the permanent support column that goes at the west end of the center spine. Guess you could call it a "tailbone".

I can't figure out where these will go:

Been waiting for this. I have a lingering question though. Are some sections of the "ribs" cut where the craine stands?

The crane towers were custom built so that the ribs pass right through them. Those sections of the tower are made of smaller pieces bolted together so they can be taken apart and removed.

Correct.

The first section of the central arch is in place. It looks to be the third one in from the left. The first pic above shows one of the temporary A frame supports being lowered into place.
