My knowledge of disaster zones is limited, but for military deployments - the other major customer - it's pretty in depth.
Here's the thing, there are two classes of structure, basically: Temporary and Permanent.
For a temporary structure - even longer term - a modern, modular tenting system (such as TEMS: http://www.mandbmag.com/tents/index.html) has this beat hands down in pretty much every way. Lighter, faster setup, faster tear down, adaptability, etc.
For a permanent structure, seriously? It would be much easier to build a traditional wooden structure once you've decided that you need one. You could even put the locals to work (which they would need) doing so. I find it very difficult to believe that anyone would want one of these dingy, musty things over a proper wood or concrete framed construction.
So where exactly does this fit in the spectrum? I'm not sure it does.
