Great pics NYCLuver!

Wish y'all could see them through my eyes.

I may have been to hasty in my judgment of the persons who wrote the PA's quarterly report.

In the 6th pic NYCLuver posted you can see hanging scaffold, I believe the base curtain wall contractor is using it to install clips on the girts.

Are those the tridents in that picture at the base? Are they staying above ground?

Skyscrapers, you are comparing a "Big Apple" to a plum. Both are tasty but very different.

A concrete structure does not need spray on fireproofing and I have yet to meet a contractor that wanted to clean fireproofing off of glass. Also, notice all the stuff in the way on Tower One, like the crane decks and the safety nets.

Let the tower get a bit higher, let the structure take shape.

No one wants to see curtain wall go up only to see it get messed up by other trades.

Think of the curtain wall as a beautiful silk dress, it's the last thing she puts on before a night (or a century) on the town.

A concrete/rebar 60 story building and a steel beam building 60 floors tall.
Is one building stronger then the other?.

That all depends on what you consider strong.

Both can take the gravity load equally well. But steel buildings withstand earthquakes MUCH better.

They are about equal under wind loads.

In a severe fire the concrete building is stronger.

As for cost, the steel building is more expensive, but will go up faster, so it's actually cheaper, the savings being in Labor. (A concrete building is cheaper than steel when it comes to fire codes, so the bottom line cost is about the same.)

If you want to put up a 60 story apartment building, go with concrete, and pray there are no earthquakes. Otherwise, go with steel.

(One can make a concrete building as good as a steel building as far as earthquake performance, but the amount of rebar needed to properly "Cage" the concrete would be more expensive than a steel building.)

In New York, I would go with reinforced concrete, in Los Angeles, I would go with steel.

I'm a Structural Engineer, can ya tell.

Thanks Zen.
800 are working on 1 WTC today. Do you know if that will increase when the number goes to 10,000 on the entire project?.

I was there last Saturday, and this is probably not the first time this has been asked, but what's with the crane sitting at about the 10th floor, northwest corner?

Will be nice to see once this rises above the rest of the towers.

Remember also that the Burj Khalifa didn't start its cladding until the building was at around the 80th floor. There's also this building to keep in mind...



Even the aluminum cladding and window installation on the Twin Towers didn't start until the buildings were about half of their final height...

Yeah, but the point is that it is kind of rare today.

Why? Because buildings are so radically different today then they were 30 years ago? Each building is individual and has an individual time frame, so relax. It's going to be built, the tower is progressing full speed ahead, and the cladding will go up when the cladding will go up.

Looks like some insane weather moved through the city yesterday. Fortunately it looks like all is well at the site: http://www.panynj.gov/wtcprogress/live-camera.html

Liking the new viewing angle of the PA webcam... gives you a perspective on how big it's getting. They had to move the camera pretty far away to get a full shot of 1 WTC.

Is it really? If you can come up with examples to the contrary, then fine. But wouldn't it make more sense not to put up the curtain wall before construction of most of the building is complete? Would it not make sense to prevent the relatively-delicate window facade structure from being damaged by all the construction equipment and debris by, I don't know, not putting it up prematurely?

I know we're all getting tired of seeing the tower's skeleton and would love to see the glass tower finally take shape, but geez.... patience, people, patience.

The docks no longer exist today because they were essentially the dumping ground for the original World Trade Center's excavated foundation. The Battery Park City area ground is essentially all landfill.

Also, take note that the original World Trade Center site was created in a process not too different than the process used to create public housing projects - eminent domain. The previous tenants on that site was Radio Row, a thriving electronics business and residential district. Of course, the PA NY/NJ couldn't quite make the claim that this was a "slum" that needed to be cleared in the name of progress and development, as had happened to many residents throughout the city whose homes were taken and razed for public housing and other projects. But the result was much the same, only prettier and more successful.

If they keep going at this rate, is it unfair to expect they will be past the projected 55, at the end of the year?
