Section 01

1. Why an Asset Register is the Foundation of FM

Without an accurate, granular asset register, facilities managers cannot price PPM contracts accurately, ensure statutory compliance coverage, or forecast capital lifecycle replacements. Maintenance schedules built without an asset baseline inevitably lead to missed plant items and unmanaged risk.

Section 02

2. Structuring the Spatial & System Hierarchy

Adopt a standard hierarchy: Estate → Site → Building → Floor/Zone → Room/Space → System → Asset Parent → Sub-component. Aligning naming conventions with Uniclass 2015 ensures interoperability across BIM models, CAFM databases, and contractor work orders.

Section 03

3. Asset Criticality and Condition Scoring

Score assets across Business Criticality (Life Safety, Operational Shutdown, Secondary Comfort) and Physical Condition (1: Good/New to 5: End of Life / Failure Imminent). This matrix informs maintenance frequency and capital expenditure priorities.
