A galvanized a frame at 1000 sq feet is about $8,000 not including foundation / footings and install and I am not sure how well galvanized works against bombs let alone bullets. I suppose if you have a back hoe and fill you could cover the galvanized a frame....
The concrete shelters are pretty slick though. For $30,000 k they are a pretty cost affective way to put a roof over someones head even if it lasts only 10 years.
