It is indeed amazing what ironworkers have done, and still do.
This all reminded me of a PBS I saw about 20 years ago documenting the construction of One Worldwide Plaza (I found it again on
this Youtube channel, I think for the production company, which seems to have quite a few other interesting looking documentaries).
I hope they've documented the design and construction of this building from beginning to end. I suspect, given what it is, they have done. I find skyscrapers, and 'monuments' generally, and the work people do to design and construct them, fascinating.
