If you compare these two pics from http://www.pinterest.com/roadcruiser...tion-10182013/ you will see that the west side is at least as far as the east side. I think the position of the cranes is not symmetric inside the oculus, that is why it seems that the east side is ahead.

Anyway, there is progress on both sides, and it seems that the bolted parts can be erected a lot faster, so hopefully they keep the current pace..

No, Enclos has been doing several mock-ups of different sections for testing purposes before shop order was done. It certainly looks fantastic!

Port Authority has WTC space to spare
By Lois Weiss

October 23, 2013 | 1:01am

"...In other WTC news, the gleaming white marble `West’ portion of the East West Concourse that runs from the PATH station into Brookfield Place’s cool glass cube will finally open later this week.

Designed by Santiago Calatrava, the concourse was mired in architectural minutiae that threatened to delay the opening by several months.

Sources told us one of the nettlesome items was a “peg” near the ceiling and other fasteners needed to cover the joints of the side panels, which ended up requiring finely detailed fireproofing and painting.

At one point in the spring, it became obvious that each of the over 150 joints was taking eight days to complete, so a faster alternative was chosen.

“It’s great and handsome looking,” Durst said of the completed Concourse."

Good news above, and I see the first transition segment with a bolt plate on the NW corner. I believe there are two more pieces with welds to go in on the east side. The one I see on the EarthCam looks similar to the piece in the previously posted image of the last welded piece connected to the first bolted one on the ground. And it looks like it was installed as a single piece.

If they start bolting them together in pairs on the ground and installing them 2 at a time that will really speed things up. It should also be taking less time to set each piece because they can put a few bolts in and have it lined up right away instead of having to brace it into position before they weld it.

BTW it looks like in order to put the bolts in place they actually have to climb INSIDE the arch segment? And when they do the last piece in the middle how will the guy get out?

I agree. I doubt they would try to lift two at once. It would require too many pieces to be in right spot to attach to two portals. I think adjusting the arch with one portal is already time consuming.

Where is the eastern entrance to this concourse? Where does it come out at the western end in the WFC?

This picture refers to a very particular element. The arch is compused by welded segments for the first 9 or 10 members from the abutments. Afterwards the arches will be bolted to eachother.

You can see the top bevel of metal sheets is brown because these is no rust protection paint (in order not to contaminate the welding process) and you can clearly see the 3 temporary lugs (to hold pieces in place while welding is made).

The sides touching eachother are the first bolted slice flange. In fact the lips carry their own drilled flanges and there won't be any more lip stiffener in the middle of the coming segments. The man is just making a piece of rod bar going through the holes on one flange to the others on the opposite one. This to force (with a leverage) the alignment of the the holes. Then the first bolt can be tightened.

We detailed all the arch segments for the workshop. Sectors in place were called "welded", next ones are going to be "bolted", this is the only one we called "welded/bolted" for is quarter (so 4 in total).

Hope I was helpfull.

PHOTOS: Marble Underground Walkway Opens at World Trade Center
http://www.dnainfo.com/new-york/2013...d-trade-center











Quote:
LOWER MANHATTAN — A 600-foot underground walkway linking the World Trade Center with Brookfield Place opened to the public Thursday.

The WTC west concourse offers the first glimpse of the highly anticipated Santiago Calatrava-designed World Trade Center PATH transit hub, which will fully open in two years.

The marble, white-arched passageway connects the temporary WTC PATH station, which has an entrance at West Broadway and Vesey Street, with the glass-enclosed Brookfield Place Pavilion across West Street in Battery Park City. The pavilion also opened for the first time Thursday.
Quote:
The pavilion and passageway will eventually lead to the rest of the $3.9 billion WTC transportation hub and the nearby Fulton Transit Center, which are both still under construction.
