Building in solid rock, unless you have a suitable cavern to use as a superstructure, will require blasting and drilling, which also will exceed the scope of this page.In areas with poor drainage or a high water table, the option of building deep will require more engineering than this page will offer. Soft soil can offer only limited resistance to bomb energy, so building in soft soil requires a deep excavation with highly reinforced construction.

Bomb shelters must be able to sustain minimal damage in a near miss or direct hit from exploding ordinance.X Research source Here are some explanations why this is critical to success. To be successful on this project (where failure could, one might assume, leave you dead) requires a thorough survey of the site you choose. Develop a site plan for the location you plan on building your bomb shelter at.
