[GSBN] Lightweight concrete roofs

[Bob Theis]

We've been considering this technique for work in Haiti, but I never  
got a reply to my email to George Nez, asking, among other things,  
whether the technique has progressed beyond the experimental roof  at  
the University of Colorado.

Does anyone know of further work with it? I'm especially wondering if  
someone has tried making corrugated or folded plate panels.
