Common use cases
- Early project scoping
- Comparing prefab, custom, and retrofit shelter approaches
- Matching threat model, budget, site conditions, and maintenance reality
Knowledge base category
Shelter Types
Compare private underground bunkers, protected rooms, storm shelters, earthbag structures, steel systems, concrete systems, and compound-scale protected-space concepts.
System risks
- Choosing a shell before the support systems are mapped
- Confusing storm, fallout, safe-room, and long-duration occupancy requirements
- Treating buried structures as simple storage containers
Planning questions
- Is the project above-grade, below-grade, or hybrid?
- How long must the space remain occupiable?
- Which systems must keep working without outside infrastructure?
