🧱 RTT Facilities — Domain Specification

Canonical Substrate Definition

This document defines the RTT Facilities domain as a shared substrate for all facilities‑related initiatives, including domain‑specific extensions such as RTT‑AGERI.

It is grounded in the original RTT Facilities Playbook capture and serves as the authoritative reference for scope, lifecycle, governance, and cross‑system integration.

1. Domain Definition#

Facilities are the physical, operational, and communicative systems that enable cities and regions to function safely, reliably, and continuously.

RTT Facilities treats infrastructure as living systems, governed across:

• Asset classes
• Lifecycle phases
• Risk and failure modes
• Capital timing
• Governance and accountability
• Multi‑audience communication

Facilities work is inherently cross‑system and long‑horizon.

2. Asset Classes#

The Facilities domain encompasses, but is not limited to:

• Electrical infrastructure (above‑ground and underground)
• Water systems
• Wastewater systems
• Transportation corridors
• Communications infrastructure
• Public buildings
• Emergency and resilience systems

Each asset class may have one or more domain‑specific initiatives (e.g., RTT‑AGERI for above‑ground electrical systems).

3. Lifecycle Framework#

Facilities are governed across the full lifecycle:

1. Design
2. Construction
3. Operation
4. Maintenance
5. Modernization
6. Decommissioning

Scoring, audits, and interventions may occur at any lifecycle phase, but modernization decisions are explicitly aligned with capital timing cycles.

4. Risk, Failure, and Propagation#

Facilities governance explicitly accounts for:

• Asset degradation and drift
• Environmental and climate stressors
• Human and operational factors
• Failure modes and cascading failures
• Cross‑system propagation (e.g., electrical → water → emergency response)

Domain‑specific initiatives may model propagation internally, but cross‑system propagation is governed at the Facilities level.

5. Governance Model#

Facilities governance operates across multiple layers:

• GHQ — global standards, scoring systems, audits, indices
• Cities — implementation, operations, capital planning
• Operators & Contractors — maintenance and modernization execution
• Residents — safety, awareness, and public trust

Governance artifacts include:

• Constitutions and charters
• Audit protocols
• Escalation pathways
• Capital and accountability integration

Facilities governance prioritizes early detection, transparent decision‑making, and public accountability.

6. Capital Timing & Modernization#

Facilities modernization is aligned with:

• 10‑year tactical cycles
• 20‑year strategic cycles
• 50‑year generational cycles

Scoring systems and audits inform when and where capital is deployed, replacing reactive maintenance with governed modernization.

7. Audience Segmentation#

Facilities documentation is intentionally segmented by audience:

• GHQ
• City leadership and operators
• Contractors and maintenance teams
• Residents and the public

Each audience receives purpose‑built artifacts to prevent scope bleed and maintain clarity.

8. Domain Extensions#

Domain‑specific initiatives live within the Facilities framework and inherit its lifecycle, governance, and capital logic.

Examples include:

• RTT‑AGERI — Above‑Ground Electrical Resilience Initiative

Domain extensions must:

• Reference this Facilities spec
• Avoid redefining shared concepts
• Provide domain‑specific scoring, standards, and guidance

9. Canonical Status#

This document is canonical.

Changes should be rare, deliberate, and coordinated with GHQ governance.
Domain‑specific documents should reference this spec rather than duplicating it.
