That's because they want the core to be a refuge from any **** that happens. Brilliant idea.

I wonder what the core's steel structure will look like higher up, perhaps smaller thinner beams or something?

Looks such a weak core (because of the thin steel beams) in the pics but should be very resistant and safe. Great pics...

Come on people. The steel is going to be encased in concrete. How many times does this have to be said?

Is the official height (1.776 feet) measured from Vesey Street/12th Avenue? Does anybody know what is the total (actual) height of the tower itself (I mean, from the bedrock)?
I have the same question about the former twin towers. Was the height of the towers (1.368 and 1.362 feet high) measured from the street level or from the plaza level?

Thanks!!

So that concrete core will be lifting alot each time is rises.. crane alone would weigh around 200 tonnes-plus..

Sharpies. Lots of them.

Or aluminum cladding. Take your pick.

From earthcam, it appears that the formworks for the north core have jumped today! Finally!!

BS, you cannot build a structure that withstands multiple airplane crashes. The architect from WTC 7 e.g. has designed it that it can stand 12h after a plane has made major structural damages to it.So habitants have enough time to escape.Its virtually impossible to construct anything that can 100% withstand a single airplane crash, not to mention a multiple! We should care about what exactely we say here and not speak out exxagarated speculations and things we dont know for sure.

I believe 1WTC is supposed to withstand more than one plane crash, that' true. The concrete walls of the core are 3 feet thick and all the concrete is three times stronger than New York City building codes. The real reason the Twin Towers fell was because the steel was weakend by the fires started by the plane fuel, not due to force of the planes cashing into buildings.

It didn't melt... it was only weakened by the heat

The north core form has been raised. Before they were flush with the formwork for that floor, but now they are above them.

I believe the Twin Towers were 1,368 feet and 1,362 feet measured from Street level not the plaza. One World Trade Center will be 1,776 feet above street level.

<Zen gets out the prints and takes a look, does some calculations and begins to type>

Tower One is 1,368 feet high from the finished first floor (elevation 311' 2") to the top of the parapet (elevation 1,679' 2"). The communications mast (or whatever is going to go on top) brings it to 1,776 feet.
