Technical Hierarchy (ISO 14224).
A 9-level equipment taxonomy that turns your P&IDs, SLDs and vendor drawings into a queryable asset structure — the foundation for every downstream reliability decision.
What we produce
- ·Site → System → Equipment Unit → Sub-unit → Component boundaries
- ·Consistent tagging so CMMS, DCIM and EPMS can reconcile
- ·Documented equipment boundaries (what is 'the chiller' vs 'the chilled-water plant')
- ·Traceable back to the source drawing revision
Data-center examples
| Level | Chiller example | HV transformer example |
|---|---|---|
| 1 Industry | Data Center | Data Center |
| 2 Business Category | Colocation | Colocation |
| 3 Installation | TKO Campus | TKO Campus |
| 4 Plant/Unit | Chilled Water Plant A | 11kV Switch Room |
| 5 Section/System | Primary loop | HV distribution |
| 6 Equipment Unit | Chiller CH-01 | Transformer TX-02 |
| 7 Sub-unit | Compressor | Windings |
| 8 Component | Bearing set | Bushing |
| 9 Part | Vibration sensor | Buchholz relay |
Why it matters for AI-era halls
New density and liquid-cooling assets (CDUs, manifolds, rear-door heat exchangers) are being bolted onto legacy hierarchies. Without a refresh, criticality and FMEA inherit the wrong parents — and energy-audit evidence for critical building services won't reconcile.
A reliability assessment scoped to one hall.
Fixed scope, fixed fee. You leave with a baseline asset model, a FMEA-ranked risk register, and an evidence starter pack.
