Comment: Monolithic concrete domes

(See in situ)

Monolithic concrete domes

are where I'd look for a truly "permanent" structure that can actually handle a tremendous amount of exterior weight. And the cost is basically on par with these....?

I don't know. Very expensive and heavy, but robust temporary structures or just very crappy permanent structures?

The more I think about it the dumber it seems. You could have a far nicer temporary structure for the same cost and less time/equipment or a far better permanent structure for the same cost/equipment, but slightly more time. I just don't see a place for this "technology", even in the military.
