Though it really doesn't show in my Google Sketchup model the column is a parallelogram. The section is far too long to be a bit of the "East Box Girder". As the man with the prints I'm calling it a super column. Time well tell. Either way, it's progress.

I know the object is much longer than any of the box girder segments that have already been installed.

Anyway, we shall find out soon. I hope the Earthcam doesn't malfunction again. It didn't update for several hours last night or this morning.

Box girder...

The more I stare at it, the more it looks like an upside-down "A" section of the box girder, but at least twice as long as the already-installed piece.



The uncertainty adds a little excitement to it all...

Edit: Here we go. Red is what has already been installed, and yellow is the section that is on the ground. (I suppose the new section could end up going to the north rather than the south.)

Now that I see it in direct sunlight I think y'all are right, box girder section. It's actually too small to be a super column.

I think it's an A too. Be kind of hard to build it from the top down. We'll find out in time.

When finished it will support the entire east side of the PATH station roof.

The big piece of box girder has been installed last night!

Two more are waiting!

Indeed, and they didn't wait for the weekend for a change.

I just realized that at the factory they weren't just checking that the sections would fit together correctly. They were actually doing part of the fabrication of the sections by assembling (at least some of) them from smaller pieces. Here we can see that a "C" section is missing its top and one side:



Here "C" has its other side, but is still missing its top. A worker is welding or cutting inside of a "D" section:



Even with today's computer technology and robotics, I guess they can't just fabricate the sections independently of each other at the factory and then assemble them for the first time in the field.

Swiddle I think you are exactly right.

Robots and CAM and all that are fine for making 10,000 units of something, but making one really big box girder, that's for craftsmen and big hammers.

Would you want to take a chance and send something as big as one of those box pieces out to the field not knowing for sure that it would fit ?

It would only be a very minor setback if some of the sections didn't fit together -- just a loss of a few hours and a couple hundred dollars.

Pics from SalSchiano from WiredNY, last night:

Did anyone see where the pieces were put? Can't spot them on earthcam..

Some time lastnight, during a break in setting up a new tower crane at Tower 2 the 18000 set the "E" section of box girder. Looks to be about one third of the entire girder now. I also see lots of temp supports for the Central spine over at the PATH station.

Side note: If the steel is sitting on a Harris truck, the part was made in South Plainfield, NJ by MRP LLC. The box girder is being made by the ADF Group at there plant in Canada.

OK, this time I have verification from a reliable source.

The first super column has been sitting there in the east tub near the 18000 for days now.

Photo by Patapsco over at SSP.

It's sitting there just below and to the right of the 18000, in two halves.

Look! Down on the ground! It's a box girder! It's a pillar! No, it's Supercolumn!

I was expecting several of the arch sections to be left out until the north tower crane is removed, with the south tower crane or a smaller crane placing them later on. But no, they're sticking the arches through the tower.



Will be interesting to see if the same is done for the top segments.

Earthcam shows that indeed the same is done for the top segments! Does anyone know if the arches also go through the southern crane?

One more thing, are there any photos from inside the temporary station? I would like to see how it looks from inside and how much of the work going on around it is visible from the inside..

I've been wondering the same thing, so I looked back through a couple threads for clues. Snipped from the original size of this photo from ajagendorf25:



We can see the north crane's tower in the foreground, and its base was designed to allow for the pass-through (no diagonal braces to get in the way). The south tower is the same, and we can just barely see one arch segment going through it.
