Back in the 1980's the threat of nuclear was a real threat to many Americans.
Things You Will Need
Building an underground bunker is a serious undertaking. You will need the advice of a liscensed contractor, a building permit, heavy machinery, power tools, surveying equipment, professional electrician and HVAC technician, and a licensed inspector. You will also need lumber, concrete, and rebar to construct your underground bunker.
Step 1First you will need to consult a licensed contractor to develop a design and construction plan.
Step 2With your contractor, you can now begin actually building your bunker. You want to make sure that the exterior walls of your bunker are concrete. I recommend at least 12 inch thick walls, but you can increase this at your preference. You can frame the inside walls with regular stud 2x4 and use sheetrock to create a familiar presence inside. Make sure all of the electrical and ventilation is complete before finishing your bunker.
Lastly, you want to ensure that you have stocked your underground bunker with enough supplies to last you and your family for at least 6-12 months. You can stock for as long as you feel comfortable but this should be a minimum. make sure you can included ample storage space for all of your supplies. You never know how much time you will actually have to spend in your bunker in the event of a real emergency, so it pays to be cautious.
We all hope that an underground bunker never actually has to be used. But, it is one thing that you certainly do not want to take the chance in not having!
