Hi all.

Hi roman.

All tall structures sway in the wind. Some more than a meter in the strongest winds they will encounter - the plan is to control the frequency so as to not make it so noticable. To make something very tall completely rigid also makes it brittle. The BK can sway 1.5 meters each way ...

Fury,

Thanks for the correction, but I thought that was implied. When I say " reason why rarely skyscrapers today have any swaying at all" , with "any swaying at all" I mean "perceivable", and always compared to structures of equal size (when I'm comparing structures from different time periods).

For example, Trump Tower in Chicago has a less swaying than towers of equal size built decades ago. So that it is almost imperceptible. Something that helps when you are selling the penthouse since not many people like living in a place that does not "seem" stable.

Anyways, your correction was needed and appreciated

Rebuildgroundzero-Webcam is back (hopefully not just for a few days..)

Direct link: http://www.malistebde.com/groundzero...11/rgz_000.jpg

Well suited to follow the cladding progress and the top of the building, especially when the discovery cam on 7WTC no longer catches the top!

The Waldorf Astoria or Astoria,Queens? If it is the Waldorf, then why not stay at the Millenium Hilton? You can get a suite there for about $350 per night with PERFECT views of the entire construction site.

Astoria queens, i have friends there. But i've already been to "Sir Harry's" barlounge in the Waldorf Astoria. It's a perfect place to enjoy a selfmade ginger ale. :-) and you get a refill for free haha xD. Sorry for getting offtopic. ;-)

I usually don't repost pictures, but never say never

I wouldn't be too sad if they stop steel construction now or during the next two months. With the current height it would be a nice addition to New Yorks skyline.
Luckily this building was not made to fit into the skyline, but to stick out of it. So there are still more than 200 yards to go. Halftime show is over. Prepare yourself for the 3rd quarter

An office in the corner would be cool with the small angled windows!
