blast resistant modular buildings for security and safe haven purposes

I'm exploring avenues of interest regarding "Blast resist= ant modular buildings".

My interest today is to explore the need of these buildin= gs for safe havens and security purposes.

I am associated with multiple manufacturers of these cust= omized buildings.

The wall thickness varies pending the blast pressure (bul= let penetration size prevention in certain apps) and generally ranges from 1/4"= to 1/2" thick metal.

These units are distributed globally and are heavily on/o= ff shore in the petrochemical environment.

Internally they can be configured to satisfy the simple n= eed of showering or to the latest of computerization.

Pending normal business credit issues the units can be ou= tright purchased or can be rented making it easy for middle management to satisfy = the needs of safety or security.

Commonly the units are transported via tractor trailer (3= 0' to 40'

each building) or can be rigged with axles so that it can= function as a mobile command center.

Multiples of the buildings can be stacked together to cre= ate multi-level &/or multi-room field offices.

These are not in any way lightweight designs that will bl= ow apart in a low order hurricane or sustain damage by common household catast= rophe means.

Any feedback is appreciated.
