If it's 1:16, then each side would be 87.375 feet (1398/16).

If it's 1:19, then each side would be 73.579 feet (1,398/19).

If someone gives me the square footage I can check to see which one it is.

We know the building is 93.5' square so if the height stays at 1398'
the ratio is 1:14.935

If it ends up being actually 432 m then the ratio will be 1:15.158

I think if there's a such tall building in Manhattan will makes other buildings looks too short,the average height of midtown buildings is only about 200m,so this contrast is extremely big.
But I think build some such tall towers in Staten Island is wonderful,when I see the photos which takes at the GE Building's observation deck,I always imagine some towers above 1000m build in Staten Island will makes the scenery more attractive.

This is probably one of the best shots of a crane in action we've ever had. It being so close to the cam you can actually appreciate the size of the crane. I've noticed they have people walking around doing things on it while it is in action!!

Looks like new vertical rebar around the core is being put up right now!!

Any construction people around to tell us what we are seeing?

A lot of new rebar. I even see horizontal rebar to the right of the crane on the 56 cam. I don't think it is just lying there, I think it is already in place for the floor slab. The rest of the site is covered with wood, so there is no telling what they have already poured

3:30 and they are still working when normally they quit at 3:00 on the dot. This is good. Lots of progress today. Maybe one huge pour late next week?

Based on what I am seeing I am guessing 3 weeks for each basement floor. That should get them at grade by January if that is accurate.

Just seems like that FAA ordinance has been around for (as long as I can remember),, Just seems like in this day and age, of the futuristic skyscraper,, (several being built over 2000ft) they could, and should amend the height to 2500 to 3000Ft, in the US. One ? arrises why is there a 2200 ft radio mast in the Dakotas? On a different note, I know Hong Kong's ordinance says nothing can be taller than the surrounding Mountains,, Or else they were shooting for 2000ft with ICC, but had to downsize it to just under 1600, due to the ordinance..

I'm not a genius when it come's to skyscrapers,, can anybody answer,, looks like this bldg is "mostly" concrete from the renders,, even if there's a bunch of steel at 1400 feet,, how does the concrete keep from cracking in the wind, with such a narrow bulding at the dimensions it is??? Knowing the wind is definitly always blowing up in the air when it seems breezless "downhere"?

The most important feature allowing building with such proportions is probably tuned mass damper to be installed at a top of the tower. By swaying in the opposite direction to the towers sway it helps it stand straight.

The design is nice,other buildings with such height always be designed very thick,I have tired of that kind of shape,but this building is so slender and good looking.
Box shape is a classic design,and with the nice cladding will be better,I like the cladding of old WTC and Aon center,hope this building will also get the nice cladding.

also, i don't know the technical term for them, but every ten floors or so are those open air spaces that are supposed to help the building withstand turbulent wind forces
