🛠️ RTT Facilities — Intervention Playbook
From Detection to Action
This document defines the Facilities‑level intervention framework used to translate observation, scoring, and governance decisions into coordinated action.
It is grounded in the RTT Facilities Playbook and applies across all Facilities domains, including RTT‑AGERI.
1. Purpose#
Facilities interventions are not ad‑hoc responses.
The purpose of this playbook is to:
- Provide a shared intervention vocabulary across domains
- Ensure interventions are governed, auditable, and predictable
- Align action with lifecycle phase and capital timing
- Prevent escalation through early, proportional response
- Maintain public safety and trust during change
Domain‑specific initiatives extend this playbook with asset‑specific detail.
2. Intervention Triggers#
Interventions may be triggered by:
- Scoring thresholds (drift, harmonics, propagation)
- Audit findings
- Environmental or climate events
- Operational incidents
- Cross‑system dependency risk
- Governance escalation
Triggers are documented and reviewable, not discretionary.
3. Intervention Classes#
Facilities interventions fall into three primary classes:
Class I — Preventive Interventions#
(Early, Low‑Disruption)
- Target emerging risk
- Occur before service degradation
- Often align with routine maintenance windows
Examples:
- Targeted reinforcement
- Monitoring upgrades
- Minor component replacement
Class II — Planned Modernization#
(Capital‑Aligned)
- Address structural or systemic risk
- Aligned with 10 / 20 / 50‑year cycles
- Require governance approval and public communication
Examples:
- Corridor upgrades
- Redundancy introduction
- Standards‑based replacement
Class III — Emergency Response#
(Immediate Safety Action)
- Triggered by imminent or active failure
- Prioritize safety and continuity
- Followed by audit and root‑cause review
Examples:
- Emergency shutdowns
- Temporary bypasses
- Rapid stabilization measures
4. Lifecycle Alignment#
Interventions are mapped to lifecycle phases:
| Lifecycle Phase | Typical Intervention |
|---|---|
| Design | Standards correction |
| Construction | Compliance enforcement |
| Operation | Preventive intervention |
| Maintenance | Tactical stabilization |
| Modernization | Planned replacement |
| Decommissioning | Safe retirement |
Interventions outside expected phases require justification.
5. Governance Flow#
All interventions follow a governed flow:
- Detection — scoring, observation, or incident
- Classification — intervention class assigned
- Review — governance threshold applied
- Authorization — approval recorded
- Execution — coordinated action
- Audit — outcome reviewed
- Learning — models updated
This flow preserves accountability and learning.
6. Capital & Resource Integration#
Interventions are explicitly tied to:
- Capital planning cycles
- Resource availability
- Workforce capacity
- Contractor coordination
Emergency interventions may bypass capital planning but must be reconciled post‑event.
7. Cross‑System Coordination#
When interventions affect multiple systems:
- Facilities‑level governance is invoked
- Cross‑system propagation risk is assessed
- Communication is coordinated across stakeholders
No domain intervenes in isolation when dependencies exist.
8. Public Communication#
Interventions that affect residents require:
- Clear explanation of purpose
- Advance notice when possible
- Safety guidance
- Post‑intervention reporting
Public trust is treated as a critical success metric.
9. Relationship to Domain‑Specific Playbooks#
Domain initiatives (e.g., RTT‑AGERI):
- Reference this playbook for intervention structure
- Define asset‑specific actions and thresholds
- Provide technical execution detail
They do not redefine intervention classes or governance flow.
10. Canonical Status#
This document is canonical.
All Facilities domains must reference this playbook when defining interventions.
