← BackInfrastructure Planning
Purpose: plan scalable water, power, transport, and service infrastructure with phased growth and resilience controls.
Quick Start
- Map critical services and dependency chains.
- Prioritize life-support systems first.
- Design modular phases, not one-shot buildouts.
- Define contingency modes for each utility.
Priority Matrix
| System | Priority | Redundancy Need | Failure Impact |
|---|
| Water supply | critical | high | immediate health risk |
| Power core loads | critical | high | service collapse |
| Transport access | high | medium | response delays |
| Comms network | high | high | coordination failure |
| Secondary amenities | medium/low | low | comfort reduction |
Decision Table
| If this happens | Do this now | Backup action | Verify |
|---|
| Demand exceeds capacity | activate demand shedding tiers | deploy temporary module | critical loads maintained |
| Single-point failure found | add bypass path | stock emergency spare kit | service continuity test passes |
| Budget cut mid-phase | protect critical scope only | defer noncritical modules | core objectives still met |
| Site disruption event | switch to contingency mode | relocate temporary services | minimum service levels restored |
Common Mistakes and Fixes
- Mistake: no phased roadmap. Fix: staged architecture with checkpoints.
- Mistake: hidden cross-dependencies. Fix: dependency graph review.
- Mistake: no fallback load plan. Fix: predefined shedding tiers.
- Mistake: weak maintenance integration. Fix: lifecycle cost and service schedule from start.
Scenario Drills
Drill 1: Utility Outage Simulation
- Take one utility path offline in model.
- Run contingency switchover sequence.
- Measure downtime and impact.
- Goal: restore critical service within target window.
Drill 2: Capacity Spike
- Simulate 30% demand surge.
- Apply demand tier controls.
- Validate critical systems remain stable.
- Goal: zero critical service interruption.
Printable Checklist
- [ ] Critical systems mapped
- [ ] Dependencies documented
- [ ] Phased roadmap approved
- [ ] Redundancy points installed
- [ ] Contingency mode tested
- [ ] Maintenance plan integrated
- [ ] Review cadence scheduled
Safety note: infrastructure planning fails when resilience is postponed. Build fallback paths early.
