Blooody hell!!! That is just sweeet!!!!


For those who aren't familiarized with the geometry, the pic shows a huge arch segment with transition pieces being welded into it. The whole thing should be turned 90° counter-clock wise. Large railing things just left to these folks will eventually hold the skylight machinery. At the beginning of the very first arch segment (just in front of the pic) is noticeable what is called the exhaust vent cylinder.

Little holes are exhaust vents on rendering. v

Thanks.

Those are the metallic catwalks I referred early, should be the last major components to be installed, they will protect the machinery from weather and allow maintenance personnel access the skylight.

Wow! Thanks for the explanation and renderings, Otie. Makes one realise the outside of this structure is only half of it. I wonder how the skylight-mechanism is going to work! It sure looks like a pain in the ass making this thing weatherproof

Upper portals, arch segments+transitions, rafters are made in the 4/5 workshops they have in the area. The picture was taken few days ago.

the sectors shown are the middle ones, close to the middle of one arch because the surfaces are less skew.

You can clarily see the connection flange, the fan conduit inside, the lip touching the ground (with the lip flange) and the transiction segments being welded to the arches. Small pipes (in couples) are for electrical pourposes. The arches also have a short portion of lower upperportal that will be welded on top of the main upperportals you altready see on site, but at this stage of the works, in the pic, those elements are not in place yet

As Otie said, this position is just for workshop preferable works. the segments will then be separated and shiped. To check the perfect geometry of the sequence after we have modelled the whole arch, with the help of a laser scanner, all the main corners and edges are monitored during welding and verified.

The fabrications for some of the other projects they are working on is also extremely impressive. Especially the size (and probably weight) of some of them is huge. Although I suspect that the geometry of none of them is any more complex than that for this project.

For a moment I thought that Calatrava himself was the guy placing the steel...until I realize that your text started on the right of the picture

Amazing that it is made in Italy, home of spaghetti?

I must say, this project was quite difficult, but we have made many high complex jobs with really good results that were fabricated in Italy. We are not that bad, to be frank!

Otie, forgive me if it's been asked before, but will the skylight slide into the pocket between the catwalks and the main structure?
