🔁 RTT Facilities — Lifecycle Framework
Governed Infrastructure Across Time
This document defines the Facilities lifecycle framework used to govern infrastructure systems across time, risk, and capital cycles.
It is grounded in the RTT Facilities Playbook and serves as the canonical lifecycle reference for all Facilities domains, including RTT‑AGERI.
1. Purpose#
Facilities systems evolve continuously.
The purpose of this framework is to:
- Treat infrastructure as a living system
- Provide a shared lifecycle vocabulary across domains
- Align scoring, intervention, and modernization with time
- Prevent lifecycle blind spots and deferred risk
- Preserve institutional continuity across generations
Lifecycle awareness is foundational to governance.
2. Lifecycle Phases#
Facilities assets progress through six canonical lifecycle phases.
Phase 1 — Design#
Intent Formation
- Requirements defined
- Standards selected
- Risk assumptions established
- Future conditions anticipated
Governance Focus
- Standards alignment
- Long‑horizon suitability
- Avoidance of future lock‑in
Phase 2 — Construction#
Physical Realization
- Assets built or installed
- Design intent translated into reality
- Initial quality and compliance verified
Governance Focus
- Compliance enforcement
- Documentation integrity
- Early deviation detection
Phase 3 — Operation#
Active Service
- Assets deliver intended function
- Performance monitored
- Environmental and load stress applied
Governance Focus
- Performance stability
- Drift detection
- Early harmonics identification
Phase 4 — Maintenance#
Life Extension
- Wear addressed
- Minor degradation corrected
- Service life extended
Governance Focus
- Preventive intervention
- Cost‑benefit balance
- Avoidance of maintenance‑only traps
Phase 5 — Modernization#
Planned Renewal
- Assets upgraded or replaced
- Systems realigned to future needs
- Resilience and redundancy introduced
Governance Focus
- Capital timing alignment
- Risk reduction
- Public communication and trust
Phase 6 — Decommissioning#
Governed Retirement
- Assets safely retired
- Environmental and continuity risks managed
- Knowledge preserved
Governance Focus
- Safety and compliance
- Transition planning
- Institutional memory capture
3. Lifecycle Is Not Linear#
Facilities assets may:
- Loop between phases
- Occupy multiple phases simultaneously
- Re‑enter modernization multiple times
- Skip phases under emergency conditions
Lifecycle governance prioritizes awareness, not rigid sequencing.
4. Scoring & Detection Across the Lifecycle#
Scoring frameworks apply throughout the lifecycle:
- Design / Construction — standards deviation
- Operation / Maintenance — drift and harmonics
- Modernization — propagation and capacity alignment
- Decommissioning — safety and continuity risk
Early detection is preferred at every phase.
5. Capital Timing Integration#
Lifecycle phases intersect with capital cycles:
- 10‑year — tactical stabilization
- 20‑year — strategic realignment
- 50‑year — generational transformation
Modernization is treated as a recurring lifecycle phase, not a failure state.
6. Governance & Accountability#
Lifecycle transitions trigger:
- Governance review thresholds
- Audit focus shifts
- Intervention class changes
- Public communication requirements
Lifecycle misalignment is treated as a governance risk.
7. Relationship to Domain Extensions#
Domain initiatives (e.g., RTT‑AGERI):
- Inherit this lifecycle framework
- Map domain‑specific assets to lifecycle phases
- Define phase‑specific scoring and interventions
They do not redefine lifecycle phases.
8. Canonical Status#
This framework is canonical.
All Facilities domains must reference it when defining scoring, intervention, modernization, and governance logic.
