away from the discussion about cranes (it certainly is a big one), here you can find quite regularly updates of the whole site (including tower 4):

In my opinion they should have made a different monument and make twin towers instead of this single one, maybe with a nice designed sky bridge between them. This tower just deserves a twin brother.

It's a quirk in the software. When the thread gets near the end of a page, it starts listing the next page even though it doesn't exist yet.

Surprised nobody's mentioned the massive concrete pour on the memorial today, which is now covered with wood like the earlier pours were. I wonder why they rebar and pour the exposed section about the north edge of the south pool? They did on the other side of the memorial entrance hole.

what really makes me mad about supertalls is they always seem to get setbacks and end up going on hold or being cancelled. im just glad that this building WILL be built. I really enjoy the design

This is great news! For some reason, I was thinking they wouldn't start erecting them until the end of September.

The PANYNJ schedule for Freedom Tower last year stated that installation of the beams would not happen until Q4.

They are weeks ahead of schedule.

I've been pondering this too. The perimeter columns probably get smaller/lighter at higher levels, but it's hard to believe that the ones just beyond the reach of the crawler cranes are significantly smaller than the ones within reach. Perhaps the crawlers just help get the columns in a position so that the tower cranes can safely lift them?

The perimeter columns on the lower floor (mostly the lobby) are more than triple height, so it is likely that its triple height (and assumed triple weight) is what keeps the cranes in the core from actually putting them in place.

The tower cranes had to work together to lift those columns. I don't think they can do that in all directions now because of all the erecting steel blocking the north crane. The columns will definitely get lighter as they go up. I'd guess the length is probably dictated by whatever the tower cranes can lift.
I was wondering if the crawler was going to travel down Fulton St. too

It's 8:30 AM and I don't see any new columns, but the crane has been moving around a lot and I do see a lot of activity and lots of people.

WTC Tower 4 seems quite active too.

once again, the new red crawler crane will be used not only for columns but for everything else around freedom tower, that includes help build new path station, memorial building, etc...

It looks to me like the first column is laying on its side to the immediate east side of the wooden tracks and is being prepared to be lifted into place. there are all kinds of people next to it and you can see about a dozen or so people on the roof of the path station near by. Should be fun.
