The Maintenance Program
Maintenance is how Facilities keeps the floor standing, powered, and contained. The program covers both the facility plant — climate, power, water, and containment seals — and the field hardware that lives outside the wire: Instrumentation Mesh nodes and the Undertow bays that launch from the relay hangar. It runs on two rhythms, preventive and corrective, and every intervention closes against a record.
Preventive & Corrective
Preventive maintenance is scheduled work: filters, load tests, seal-integrity checks, and cold-store readings done on a cadence whether or not anything is wrong, so that hardware never drifts far from nominal. Corrective maintenance is fault-driven: it begins when something fails, degrades, or trips an alarm, and it ends when the fault is cleared and verified. The two together keep the gap between "nominal" and "broken" small enough that the floor never notices it.
Tied to Field Service Reports
Every corrective intervention is recorded as a Field Service Report (FSR). The link runs both ways: when Instrumentation Mesh fault telemetry crosses a threshold, GOVERNOR auto-drafts an FSR from the fault signature — affected node, symptom, last-good reading, and a first-pass diagnosis — and routes it to the maintenance queue before a human has seen the alarm. The technician confirms, corrects, and closes the FSR against the asset, so the program's history is the FSR history. Preventive work that uncovers a defect spawns an FSR the same way.
Maintenance Domains
Each domain carries its own cadence, owner, and governing SOP. Containment seals and field hardware run tighter than open-floor plant.
| Domain | Cadence | Owner | Governing SOP |
|---|---|---|---|
| Climate / HVAC | Monthly filter & setpoint check; quarterly coil service. | Facilities — Plant Lead | SOP library |
| Power / UPS | Quarterly load test; annual transfer-switch & battery drill. | Facilities — Plant Lead | SOP library |
| Water | Quarterly potability assay; biannual line flush. | Facilities — Utilities | SOP library |
| Containment Seals | Monthly seal-integrity test; pre-entry verification. | Facilities — Director-reviewed | SOP library |
| Instrumentation Mesh Nodes | Continuous health-poll; annual node audit; fault-driven swap. | Instrumentation Mesh — Mesh Control | SOP library |
| Undertow Bays | Pre-flight & post-flight check; monthly bay service. | Facilities — Undertow Relay Hangar | SOP library |
Maintenance Tracks
Preventive
Cadence-driven work — filters, load tests, assays, seal checks, and cold-store readings — run on schedule to hold every domain near nominal. Defects found here open an FSR.
Corrective
Triggered by failure, degradation, or an Instrumentation Mesh alarm. GOVERNOR auto-drafts the FSR from fault telemetry; the technician corrects and closes it against the asset.
Containment
Maintenance on HV and CV containment hardware. Two-person, Director-reviewed, and run to full doctrine before any seal is broken. The tightest track in the program.
