Why is the uppermost part of the U/C (shown in the pictures on post #8146) covered in black tarp(?) ?

Why wouldn't it be? 1WTC had the same thing.

Also it's not a building that is covered with it, but a climbing formwork system.

The height of this building looks impossible for the footprint. It must be going to have some seriously sickly sway at the top.

You see black tarp (or many other colours) on loads of buildings around the world, varying from 20metres tall to 400metres or more, it's nothing out of the ordinary

But great pictures Brooklyn!

It is engineered to have as little sway as possible by using a mass damper.

God I love this building, its like a throwback to the older Skyscrapers with a modern twist. I firmly believe this will embed into the very fabric of the city just as the ESB, Chrysler etc. It really looks like the developers have put alot of thought into the impact on the skyline with this one and for that I'm grateful.

I hate how foreshortening makes the building look shorter than it really is when it's viewed at the base. Really looking forward to seeing this above the skyline from afar.

With the seemly random way they are installing the windows I'm beginning to think the workers are playing tetris. Why are they so random?

I think way worse is the window size. Hard to imagine how giant they are.

I hope the window size doesn't weaken the building.

Well, they're using ludicrously strong concrete... But (and someone please correct me if I'm wrong) the core is almost solely responsible for carrying to load of the building, isn't it?

For most buildings (such as this one), the core is responsible for the weight of the building. However, for some buildings such as the Old World Trade Center, the exterior wall provides the support.

It depends, you have to differentiate vertical loads and horizontal loads.

If asking about vertical loads (the mass of the building and all the objects and people it contains under the force of gravity) Then No, The vertical loads are supported roughly half and half by the core and the external columns ( I think the core a little bit more)

But if asking about the horizontal loads (wind, earthquakes) then yes, Most of the horizontal loads are carried by the more rigid core.

Edit: I thought this was the 1WTC thread. I stand corrected, in the case of this building the horizontal forces are also carried in a good percentage by the external columns, that are relatively placed together and tied by strong beams, as in the case of the old WTC, the external columns also function like a rigid wall, It is like it has a double core.

For the old WTC, it was the opposite. The horizontal loads were carried by the external columns, that were so closely placed, that they functioned like a wall. The vertical loads, the weight of the building, was carried also roughly 50-50 by the core (made of more widely separeted columns) and the external walls.

As someone who couldn't disagree more would you mind explaining your thought a little further for me, please? I'd truly appreciate hearing how you reached those conclusions.

This building does not replicate modern, glitzy skyscrapers. It's strong columns, big windows and lack of setback possess an art deco quality to them. Meanwhile, the white concrete and slender anatomy of the tower add a dash of modernism into the mix. And of course, its impact on the skyline is obvious, as it rises out of a mix of skyscrapers that are shorter than the rest of midtown.
