And do you know what was the total height of the whole former twin towers' structure? I mean, do you know how far was the street level from the bedrock (I suppose it's the same with this tower, the Freedom Tower)?

I believe I read originally then there are supposed to be 4 tower cranes when full construction began.

The site plans call for 2 more cranes to be added to the north and south sides of the tower some time after all the ground floor and plaza slabs are in place.

The server crash last night prevented me from adding to my last post.

The bottom floor B4 is at 240 feet, or 71 feet below the first floor. The foundations go 4 to 12 feet deeper, then there are the rock anchors that go 80 feet below the top of the foundations.

So, from the lowest basement level to the top of the parapet is 1,439 feet.
Measured from the bottom ends of the rock anchors to the top of the spire Tower One is 1,927 feet.


From what information I have (the prints for the Memorial) the Twin Towers went just as deep give or take a foot or two.

We should care about what exactely we say here and not speak out exxagarated speculations and things we dont know for sure.
Actually, I wouldn't be surprised if the towers were able to withstand multiple impacts. The 767s only removed about 15% of the core and exterior columns of the towers on 9/11, so even they probably could have withstood more impacts, and the new WTC1 is designed specifically to be stronger than the original towers. So withstanding more than one plane crash wouldn't be a surprise and certainly isn't an exagerated speculation. The reason the towers collapsed on 9/11 was from the fires, not simply damage from the plane impacts.

Actually, they seem to like to pour concrete on days when it's raining out.

Typically buildings are measured from the street level that the main building entrance is situated on ie where the buildings adress is situated. many buildings have service or side rds that may be lower but dont count

I hope there are plans for a defense system. They will probably remain secret, however. On a bus tour of the Hoover dam, the tour guide said look up at the top of those hills. If he hadn't told us, I would never know.

THIS IS ONE OF MANY EARLY RENDERINGS, WHICH IS NOT BEING BUILT:

The first rendering in RKOwens post is the latest rendering, it also matches the prints.

With the MTVA deal officially dead the communications rings and mast are probably going to change.

One of the things that struck me about the communications mast is that the guy wires are 6 inch diameter Kevlar.

A new quarterly report (1Q2009) was just released on wtcprogress.com.

The second quarter milestones for 1WTC are,

Complete North Core Shearwall to B1:
Complete placement of reinforcing steel and high strength concrete for the North Core of One World Trade Center to bring it up to the B-1 level – the last level before grade.

South Core Crane Jump: (*this appears to have already been met)
This represents the movement of the southern tower crane from the supports within the South Core to the erection steel above the core. This movement will facilitate continued erection of the southern core. The South Core Crane has already made one previous jump.

Finish Concrete Placement on the #2 – Auxiliary Shear Wall:
This will enable the start of the slab work to be located at street level, which will facilitate vehicle and equipment access to support the above-grade construction.

Complete First Three Sections of Cutback of the Vesey Street Deck:
Removal of these pieces of Vesey Street north of the One World Trade Center site will allow the installation to continue on the remainder of the building’s exterior columns and completion of basement deck construction in that area. This area of Vesey Street is already inside the fenced-off area and will not affect pedestrian movements.

I'm hoping that the ring does change. I like this look way, way better:



By the way, Zen, do you know if they're still planning on having that rain-catching idea incorporated into the roof design somehow? How would that work? I though the circular ring was supposed to be what caught the water.

Also, in the past two minutes I just saw David Shuster (he's guest hosing Countdown) claim three times that Condaleeza Rice claimed the other day that the Twin Towers were 80 stories tall. In fact, I remember her speech about this the other day and she said that she was horrified by the videos of people jumping out from the 80th floor. In the South Tower at least, I'm sure there were people jumping from the 80th floor. She never said the towers were 80 stories. No big deal, just this guy seems to deliberately lie sometimes.

6 inch Kevlar? Where in the world did you see that or better yet why in the world would somebody consider that. That sounds like a ridiculous decision.

Is anyone else able to read the "6 month look ahead" graphic in the report? The text is really small, and when I zoom in on the PDF it's just WAY too blurry to make out a single word.
