I'm posting this to get ideas for my underground bunker. I am a welder so I have decided to go the steel box route.
1-I will be building it myself.
2- I want it to be 8' tall x 8' wide x 12' long.
3- Will be using 4'x8'x 3/16" sheets. Trying to decide on the reinforcment ribs, either 3" channel (4.1 # ft) or maybe square tubing on 24" centers. Not sure what size tubing would be of the same strenghth. Or would I need larger channel??
4- Need to figure out a design for strong secure entry hatch. Second entry would be drainage tube big enough to crawl through, just in case.
5- I would like to make an elevated floor ,about 18"-24" with removable floor panels for storage underneath.
6- Still need to figure out about ventilation.
Also as said I will be doing this myself, secrecy is golden it seems. So I will be building the unit in sections and lowering them into the hole and finish welding them together down there. I still need to figure out a good rust proofing method. Was thinking about using the same type tar that you paint on basement walls defore you backfill. Any thoughts??
Also might run power from closest place to bunker for electric to run lights,dehumidifier etc. Still need a back up system though. Thinking solar??
Have well on property so a way to get water if electric is down is on my mind also.
Planning on burying this thing under 24" dirt.
All ideas are invited as I have never built one before. But that has never stopped me in the past.
Thanks
