When will they start putting in the big ribs that stick all the way out of the ground and form the main structure?

When they are done with all the underground and street level work. They still haven't installed the steel beams for the Hub at the Greenwich Street side.

Not for a long time. Like RoadCruiser said, the underground work must be completed before the "ribs' are installed. The ribs are attached and supported by the underground steel.

One step at a time.

WOW! this place just keeps blowing my mind!!! don't know if I should call it a sculpture or a building. What an experience it will be to walk through it when it's completed.

It is truly both. That is Santiago Calatrava's trademark.

What's truly amazing is the engineering that goes into this. These components are so incredibly custom. It's an a rarity to see something complex like this built in North America.

No, while half of the ribs will get attached to B1 ceiling and half to the B2 ceiling, the two steel arches surrounding the skylight will be the responsible to carry and spread every load of the ribs, until that happens they'll have to be guyed.

The first two large east/west spine spans will go in first then, Otie? And then be guyed until the north/south ribs are connected?

Just want to make sure I understand correctly.

Is it just me, or is construction of the vehicle security center moving at an extraordinarily slow pace? The circular steel lattice structure has looked virtually unchanged for three months...it just seems to be moving at a snails pace. I thought they were racing to finish this in order to avoid delaying WCT1 opening?

I don't know how you can say that. here are two pictures of the site. One from 3/13/2012 and the other from today 6/13/2012. There appears to have been a tremendous amount of progress.

Wow...it is just me lol. It's just my perception I suppose. A watched pot never really boils, huh.

IrishInNYC, who posts at WNY, works at the VSC. If you have any questions I'm sure he could answer them.

I'd say the fixed arch will go out first, but I don't have that type of info.

Looks like the Greenwich Street area is finishing off soon. All the cement work appears to be done now. They're now adding dirt on top of it. I guess that's one of the steps they need before they lay down blacktop. (that and crushed gravel)

When all is said and done, This part of Lower Manhattan will resemble a 21st century version of the massive density only a few feet away.

World Trade Center Transportation Hub Assumes Its Sinuous Form



By DAVID W. DUNLAP
July 10, 2012

It has cost much more and taken far longer than expected, but as the structural form of the World Trade Center Transportation Hub by Santiago Calatrava begins to emerge, it’s clear that New York and New Jersey will get some serious architecture for all that time and money.

Passers-by have no way yet to gauge how much progress has been made, since the work so far has occurred below street level. PATH commuters who have been threading through and around barriers know something big is going on, but cannot really see what it is. Absent any visible signs, it has been easy to focus on the budget, now nearly twice the original estimate of $2 billion, and on the construction timetable, which has stretched to 10 years from 4.

But for the first time, completion is imaginable. The public centerpiece of the project, an aboveground entrance at Church Street known as the Oculus, has taken on its finished oval shape. The sweeping ceiling beams of the mezzanine are in place. Wherever one turns, the sensuous curves of Mr. Calatrava’s design have taken tangible form.

[Innsertnamehere]

will you require tickets to enter the park when the construction is complete? or is it a permanent thing? if it is permanent, why?

[Noll]
