Dana1; we never do anything half way, yes the curved walls and round roof will also be steel SIP

Torben; We are building the "shell only", for another Builder/Developer. I don't buy into the LEED program either,as you say too expensive, We strictly do "EnergyStar" when we do "turnkey" I'll see If he has the preliminary numbers. The panels drops/cutouts are getting recycled so thats a good thing for the environment. All steel stud framing on inside, so mold resistance and good indoor air quality will be maintained

It is an impressive project. I hope you post pictures of the tower assembly. Are they doing one of the vacuum tube elevators (no pit) surrounded by stairs?

Torben; The tower will be the last thing we do so we are still a couple weeks away from that, I will ost pictures. The Elevator has a pit

VERY cool!

Starting main hip span 44 ft, across 7/12 pitch, integral hip beams are 34ft. lonh and longest roof panel is 30 ft. long

Starting curved wall.............. Notching back side of panel curved wall 28 ft, tall

Mystery corner header, how is that held up?:

Can I assume that once the notched sections are bent to the curve the interior steel on the inner skin sections get re-attached somehow to preserve the structural integrity of the monocoque?

Dana 1;

Yes the skins that are peeled off are being stitch screwed back on as shown in this picture.

a more comprehensive group of pictures are posted on www.myspace.com/steelsips

I am not an engineer, but I'd be prepared to believe one if he told me that the curved outer skin is good enough to be structural even without the inner skin (assuming outer skins of panels are soundly attached to each other).  Assuming that that wall completes at least a half-circle and is not a very large radius, that curved outer skin probably has quite a lot of strength in all directions (vertical compression/tension, axial, and shear) just on its own.

That said, if it were my house, I'd ask for some straps or something to be attached across those seams on the inside as well.

rnortman;

When skins are re-attached stitched together, V re-foamed, the curved panel will most likely be stronger than when it was flat.

FYI: radius is 13' - 6"

Round wall complete: Next ...........the 32 segmented round roof

Is there going to be beer label on this side? :-)

Dana1; once the cone roof goes on , I would like to add some fins to the side just to freak out the neighbors

I like it! Do it! (even if it's only photoshopped. :-) )

Starting circular roof ............... ................

What's happening at the top of that post?  How are the panels connected there?  Is the post temporary or permanent?

.............Underside of hip roof, the supporting member is internal at the hip, leaving a clean underside Underside of 5 sided modified hip roof...... Inside of curved wall......... From this last picture you can begin to see the enornity of the structure, 23 ft. tall side walls, underside of main roof span is 36ft. at center from slab, tall enough to install a third floor loft area over the theater
