RE: the "flying beam" - figured that was an offloading.... so we have a flanking maneuver going on. Next time photos are taken, would love to see a pic of the north side......

Looks like it's only two or three more mechanical floors before the first office floor. And with the way things are going now, that should be very soon.

Well, it worked on the Shanghai World Financial Center, and look how good it turned out. Plywood or metal forms can be cut, enlarged, or reduced in size to maneuver around the steel cage.

Another column this morning, the 19th of the 24.

NYguy, do you have a schematic showing why the column installed yesterday is slightly tilted? I know it has to do w/ the rail system, but a schematic showing the column and the base column installed long ago on which yesterday's column was attached and the relative to the location of the tracks will be instructive. This anomaly will be the source of questions for years to come and it will be great to have an instructive illustration.

I think that office floors will be from the 20th floor (so, there are a lot more of mechanical floors...)

I don't think that there is anything special here, the outer structure is always connected to the core.

Actually, from the lobby to the first office floor, it counts as floors 1-19(different ceiling height must be the culprit), and there are only 5 mechanical floors.

The Shanghai WFC's exterior was connected to the core(only that the concrete core rose faster than the building itself, vice versa for this project), however this building requires that the steel rises faster than the concrete. I was a bit skeptical about this last year, but it all makes sense now.

Wow! Construction is really moving along at a swift pace. I hope the weather stays decent for a while.

There are no floors 7 through 19 and they are erecting the 4th floor on the east side so we'll see office floors before spring.

The forms are modular and there really aren't that many beams to work around. It's also made simpler because the floor slab is actually keyed right into the core wall.

Would you settle for a pic of the north side from foundations to the 4th floor ?

And maybe a plan view too. The column in question is the third one in from the left near the top. The curved dotted lines are the PATH clearance envelope.

And one for NYGuy

Ah, my eye wasn't tricking me with the second picture. The northeast corner of the tower was slightly less chamfered than the other three corners, but I believe that's where the diagonal column is. It manages to come out to a perfect tapering when at street level, so it's hardly noticeable. And the North core...it's amazing that they managed to span the concrete over the PATH tracks without reducing it's payload. This tower never ceases to amaze me.

Thanks. It's nice to have a little clarity on just what's going on with the top of this tower. The ring will give an open "dome-like" appearance with the spire being the final piece of the puzzle.

Puzzlecraft · #**6233** Posted **Oct 16, 2009, 7:39 AM**

Zen, thanks for the schematics, much appreciated. I see that the "base column" is in fact vertical, but offset due to the tunnel, and then the tilted column making up for the offset. I was trying to visualize if the "base column" was also tilted but see that is not the case.

I curious to know if the tilted column on the north side will be visible through the eventually fancy prismatic glass wall or if cleverly hidden so that everything appears symmetric for each side.

BStyles · #**6234** Posted **Oct 16, 2009, 2:11 PM**

I hope not. That will ruin the symmetry of the tower, especially when it's backlit at night.

I like that plan view showing the PATH tracks. Thanks.

Great shots NYGuy.

Glad you like em meh cd.

Great pictures so 20 of the 24 perimeter columns are up. 4 more left 2 go and they all could and should be up by next week or the week after
