This is just a guess, but I think they are safety tie offs for workers on the scaffolding. If you look closely at the top few pictures you can see the straps hanging around the scaffolding...

Yes..One crane is enough..I was more worried about the distance between the crane and building..At first I thought they wont be able to connect the crane to the building when approaching the top..Then I took a look at the pics..Here's the situation:



Blue - Part of the building which goes to the top (306 m)
Green - Entrances
Gold - Crane position (It's right next to the entrance)
Red - Possible connection to the tower

They tryin' to use every inch of the site..Very interesting and complex construction..

That, or hangers for the scaffolding..If you look at previous pics from last month, you'll see a lot of complex scaffolding inside the lobby..My guess is that they used this to hang scaffolding to the roof of lobby..Now they have moved the scaffolding but left the straps..We'll see what will be with that..

One interesting fact..When Carnegie tops out in 2012, it will be 6th tallest building in New York and 3rd tallest to the roof, right next to 1WTC and Empire State Building..Only taller buildings in 2012 will be BofA Tower, Chrysler and New York Times Tower, only because of spires.. 4WTC will be right nex to Carnegie..

The structure will be made of concrete, not steel?

Steel construction is much faster due to the drying process of concrete correct?
The wood seen in the pictures must be used for forms.

Depends on the size of project..On some projects they use additives for faster drying..As you can see Carnegie rise 1 floor per week, the same as 1WTC and 4WTC with steel construction...

Yes, the wood is for forms..

Which form of construction is stronger? Which will last longer? Concrete or steel?

Well, this is think about which we could talk for hours..There's no definition or rule which will last longer..Everything depends on how it's calculated and projected, how it's done and how it's taken care of during usage..

At the end depends of what's goin' on around..

If fire hit building made of steel it could happen what happened to old WTC..Steel is not fireproof..(Yes, there is fireproofing spray but here depend again how bad the fire is)
But on the other hand, steel is great to hold up an earthquake while concrete is not..


As I said, this is huge theme to talk about and everything depends on what are you lookin' for in it...But to answer which will last longer, I can say only that depends on how you taking care of it..

I also have this doubt. We can only imagine where is the core, seeing the project plans. But we're not sure...
