No haha, its almost about the same height as the tallest World Financial Center tower. Should be taller than it soon.

The next vertical steel beams will surpass 7 World Trade Center, 3 WFC and almost 200 West Street (Goldman Sachs Tower)

Sorry, you are right. I misread his question as the entire set of 4 towers making a line.

I went into the city today with my camera. So I got to take some shots from another perspective.

Nice photo, it clearly shows how DIRTY the glass is.

I hope they get moving on the steel soon. The last couple weeks have been pretty mediocre.

I noticed that they constructed the entire core of the Shard before the other beams and the frame was assembled. Is there an advantage to doing it this way? Why isn't One World Trade Center being built this way?

Always like that right after a place is built. A lot of it is just dirt dust from construction.

Zen where are you, this guys got question I can't answer.

Here's a question isn't there another building, beside the shard you dude can compare this to.

The core wouldn't be that strong as far as side loading went by itself. If you had a windstorm or eathquake without the curtain wall to support it you might have a problem.

Zen has answered this question before. If I remember correctly, the Shard's method of constructing the core first and bolting the steel to it, is a more traditional method of skyscraper building. Quick and easy. With 1wtc, the core goes up aftewards and encases the steel, making the overall integrity of the tower much much stronger. In other words, it might be a little more difficult and a little more expensive, but it's a lot better.

It's because 1WTC has steel beams in the core..They have to build steel construction first, connect floor beams to them and then they wrap core steel into concrete..It's called reinforced concrete..It's strong as hell..

AND with the added statement that the Shard is plently strong. 1WTC is obviously designed to be overdone due to the locations history.

Yes..Reinforced concrete..Steel beams are in the concrete because it's way stronger than concrete itself..The best way to explain it is when you look at the pressure..If you put huge pressure on the concrete itself, it will break..But steel in that situation has ability of bending and it absorb the pressure way better..When you put steel into concrete you give this ability to the concrete..Steel makes it way stronger and absorb pressure way better..

Not so much pressure as tension. The concrete is the strength pressure wise and the steel is the strength tension wise. So if you tried to bend the core with a hurricane or airplane, the concrete would be the strength of the opposite side of the bending force and the steel the stregth on the side that was getting pushed. Same with the tower swaying in a quake sort of, except the buildings own inertia is the load.
I'm just guessing, but I think that bolting the floors to the steel frame in the core is a lot stronger than just bolting them to concrete.

Dunno if this has been posted or not, but the rebuildgroundzero.com website seems to have been hacked by somebody. The webcam is not available as of this writing.
