Will 1WTC make use of a mass tuned damper? Just curious.
Tower One doesn't need one, it's mass and structural rigidity well prevent sway that would be perceptible to people in the upper office floors.
Tuned mass dampers come in many forms and are actually rare in buildings outside of earthquake zones or structures with special considerations. The Citycorp building would fall over in a 75mph wind if it didn't have one. (Take a good look at it from street level)

ADF Group Inc. has been awarded a contract related to the construction of the Freedom Tower, Tower 1 of the World Trade Center Project. The contract refers to the fabrication and delivery of the steel superstructure and heavy steel components of an important portion of the future high-rise, a 108-story skyscraper, 1,776 feet (537 meters) high. It also includes the fabrication and delivery, in 17 different sections, of the base and mast of the 440-foot (133-meter) high antenna that will top this prestigious tower.

It looks spot on. Of course the resolution isn't that great.
The basic outline is dead on. They even have the ring supports correct and the vent hoods for the cooling towers.
The mast section count is correct but they don't mention it's weight. 440 tons. The lower mast sections are 20 feet high and they get taller as the weight decreases higher up.
Have you ever seen 9 inch solid round stock, you well if they build the spire to the current design.

The original towers were two huge boxes, therefore they had a lot of wind resistance. And to make it worse, they were positioned against the winds of the harbor.
If memory serves, one of the reasons the original towers were offset somewhat was so that when the wind blew, one tower would usually be in the other tower's wake, and this would reduce the forces on the towers.

I was 15 at the time, but I seem to remember that they were concerned with a possible resonance between the towers when the wind blew just right if they were side by side

I haven't seen a larger resolution of this pic, but good to know it's at least accurate. There have been so many revisions on this tower.

I have a few photos but I also have a quick question..if it's already been asked don't catch an attitude with me, I apologize. I was at the site yesterday and noticed these cables for the first time...what are they for?
And here are the others..they came out pretty dark.. sorry guys..was kinda in a rush also so I didn't take that many this time.
And two very bad ones that were actually kinda cool. I'll take these from an open window in a car someday.
I guess those cables are for many things: Have a look at the construction site at night: there are many lieghts. They need them to see anything. There are several lieghts on the cranes. The Subway Restaurant needs electrity too. All the machines, the cranes and several others, they all need electrity. Without electrity, no construction whould be possible.
Thank you for all the images.

(laughs) Well no offense, but of course the building needs lights and electricity..I've been there plenty of times at night. I didn't wanna guess and make a fool of myself but here it goes..They seem like tension cables for the windows that cover the lobby..?? Don't laugh! And you're very welcome for the photos!
^Yeah, your question went right over OneWorldTradeCenter's head.
I wonder if they lend some support for the open span in the lobby? Or are they purely an aesthetic touch?

Haha..Yeah, but it's alright, we all make mistakes. But as far as the aesthetic theory..I can see that too.. It definitely looks good. Surely someone will have the answer though .
I saw those cables as well. I thought you mean the other, but that whould be a funny question.
No, I think they are for the facade or the windows.
Haha no, no. I should've been a little more specific. But we're thinking similarly so maybe we're right. I keep thinking of the Time Warner Center's main lobby when I see this part of the tower..If I'm not mistaken, I believe that cables help keep the windows up in that part of the building..I could be wrong though..just an assumption.
Those cables are interesting. I would love to know the specifications on this tower. I would imagine a lot of consideration has gone into the protection of it especially near street level.
They are obviously anchored into the floor below from what can be seen in the photos and are fairly close together although not exactly very thick. It looks as if the lower beam is projecting further out than the one above so would mean that its possible it needs some support but I have never seen it done like that before. Im assuming that this particular floor must be unoccupied as I cant see them being very asthetic if in a window line.
So many questions!
