Correct! I forgot to mention the frame word. Dark green refers to the complete portal frame, which is composed by either a lower/sub portal frame and an upper portal frame.

Haven't been paying much attention to the WTC lately, but I checked the cams and saw some massive scaffolding in the hub. What's that all about?

^That's the ultimate deadline, the deal is to get it done as soon as possible.

During the last couple of weeks there's been meetings with all major contractors to coordinate and create a single scaffold and an upcoming platform that can be used simultaneously by electricians, ironworkers, skylight folks, glass envelope folks and painters.

Otie, how is it that you know so much about the Calatrava train station? Do you work there?

How will they be able to put up the rest of the "ribs" with the two cranes being in the way? They will have to remove them at some point...


And a question that does not "belong" here, I suppose: how will they be able to lower the last crane standing on top of WTC 1, will they have to use an helicopter?

Keep up the good work Otie: this forum is my daily stop!

The Skanska M1280D cranes are meticulously positioned to fit through the skylight opening.





Cranes modeled by Peter Madrigal.

Thank you for that answer, I've been wondering that too. Very nice rendering by the way (as always I should say). But now I'm wondering why they need a crawler for the rafters, because your renders make it look like the M1280E could do that job quite easily. I suppose it's because it makes them harder to dismantle afterwards, but it doesn't seem impossible either.

Also, I found some more or less recent pictures on Flickr. Here are a few of them, credit goes to Cinco.

I was wrong when I stated the crawler would come to erect rafters, it looked that way on a file I saw. Rafters will be indeed erected by Skanska cranes, from shortest to longest.

The crawler will be used to assist Enclos team on skylight installation. It looks like there's going to be stepped "dancing floors" on top of the scaffold, arranged pretty much like a stepped pyramid.

Thanks, I even modeled the boom and lines at different angles to allow easy use in other modeler's projects. Each is a separate downloadable component. You can adjust hook height by moving the block/hook and then dragging the end of the line with hidden geometry one to line up with it, I might have the templates hidden so you can rig it at a custom angle. The only thing I didn't model was the light on the tip of the boom, but the creator should be on the contributors list on the info page.

More On-Topic, It really highlights the height of the rafters.

Will probably use them for animations of construction, still in the conceptualization phase.

The red scaffold will be used by ironworkers to weld, other trades will be using these suspended, stepped "dancing platforms" hanging from the fixed arches.

Otie, do you know the welding specification for this part of the hub? See if you can find out if it is AWS D1.1 or D1.8 (D1.8 is the seismic code - used in high profile buildings, fault areas, high value targets)
