I don't; the drawings stayed with the firm I with at the time of the design. I used the ATAS standard details for their proprietary panels, but with the warning from the manufacturer that the panels were most commonly used in southern states, and that they would be vulnerable to leaking if ice dams occured, I treated the metal roofing as an outer shell for a membrane roof beneath. I set the Bermuda roof on a system purlins or sleepers that would allow any water that might get under the panels to drain down across the protective membrane below. In essence, I treated the Bermuda roof like a rain screen before the term became part of the architectural lexicon. Ideally, the rolled seams used in traditional Bermuda installations such as Kentuck Knob or Dobkins would have been water tight in and of themselves, but the budgets with which I worked at the time would not allow that level labor, so I made do with what was available commercially.DRN:
Do you still have the details of the roofs you designed?
It was noted that the ATAS system used metal caps at the hips...that was the standard and preferred detail by the manufacturer, but there was an alternate detail that would allow the "stepped hip" more commonly associated with Bermuda roofs, which is what I used. The panels on either side of the hip line met but were held apart a fraction of an inch at the hip joint. Beneath the joint, what could best be described as an inverted 'V' section step flashing was inserted to allow water that got between the panels to drain down. I don't recall exactly how the panels locked into the step flashing, but as I remember there was a means to prevent water from traveling horizontally away from the hip.

Happy scrolling ! SDR
The Carnegie Mellon PDF also shows steel in there especially over the full height french doors of the living room. There is a large steel channel in the section but there is also a smaller steel box beam laid on it's side over the top of the doors with 1-3/4 in steel angles extending from it. I don't really understand this yet
Correction to my post immediately above where I describe the apex of the hip roof. There are not two smaller rafters that frame into the western end of the larger steel flitch beam over the living room, there are three. Still there is a lot of steel and bolts where those members come together.
...Of those three smaller rafters that form the hip, the southern most one bears directly over a full length mitered glass detail! So one has to wonder how is he dispersing the weight here? It's a very heavy roof of wood, steel and copper.
B7 has some very interesting details but the notes are not legible.
Has anybody a clue what the "steel box beam" (tube steel section) is all about? Some form of lintel I guess.
Wait -- when was this book published ?

... in 2005. There is no price listed on the book. I got my copy free; Don Hoffmann sent me his copy, given to him by Mrs. Hagan.
The book is about the whole experience from Mrs. Hagan's point of view. It's not all that informative on technical matters, though there are some interesting photos taken during construction, plus a preliminary plan (pg 9) by Davy Davison, which FLW rejected emphatically (according to Geiger) and an as-built roof plan (pg 11) showing a slight error by FLW in aligning the two major roofs, leaving a flat place next to the kitchen mass that rises above the roof. Typically, FLW flew into a rage over this flaw, and blamed others for not catching it.
