Three cross-reference identifiers in this template — Maximo Asset Number, Plantroom Asset No, and BMS Asset No — and the fact that they're separate fields rather than one generic "asset number" tells you exactly what kind of facility this was built for. An airport with a CAFM system running Maximo, a BMS controller layer, and a physical plantroom tag scheme generates three different numeric identifiers for the same piece of mechanical plant. A chiller sitting in the NT Pier 5 plantroom has a Maximo work order number, a BMS point address, and a physical tag bolted to the casing. All three need to be in the record.

When Plant Lists Live in Three Different Systems

The facilities engineering team that knows where everything is tends to exist until three key people leave and the institutional knowledge walks out with them. What survives is documentation — and documentation that only lives in Maximo, or only in the BMS, or only in a spreadsheet that one engineer maintains, is documentation that fractures the moment those systems need to talk to each other during a fault investigation.

An AHU that trips out at 0300 on a Sunday night generates a Maximo work order, a BMS alarm, and a call to the on-call engineer who's trying to identify the unit from a location code and a brief description in the alarm log. That engineer needs to know: what terminal zone is it in, what voltage does it run on, who's the supplier/manufacturer for emergency parts contact, what was the inspection status at the last scheduled maintenance, and what's the BMS asset address so they can pull the trend logs. Five separate questions that this database answers from a single filtered record.

The Technical Specification Fields

Voltage — 415V three-phase, 240V single-phase, 110V — is the field that determines isolation procedure. Switching a 415V three-phase AHU offline for maintenance requires a different isolation protocol, different PPE classification, and in most jurisdictions a different permit level than a 240V single-phase toilet extract fan. This distinction is not subtle from an electrical safety standpoint. Having voltage in the asset record means a permit-to-work issued against that asset can be written correctly without the issuing engineer having to verify electrical classification against a separate drawing package.

Current and Phases extend that picture. A 100A three-phase circuit breaker for an air-cooled chiller is a significantly different isolation and reinstatement task than a 32A single-phase feed. The emergency responder who doesn't know this before they approach the equipment is working blind.

kW is the operational load figure — useful for electrical load calculations, for understanding the energy consumption profile of a zone, and for commissioning verification when a replacement unit is installed.

Pressure (bar) applies to pressure vessels, pressurisation units, F&E tanks, and calorifiers — the asset types where operating pressure is a statutory compliance parameter under PSSR 2000. A pressure vessel without a recorded working pressure in the asset register is a compliance gap. Weight applies to assets where lifting and structural load calculations matter: a large air-cooled chiller on a roof requires structural assessment that depends on knowing the equipment weight.

Inspection Status and Plant Condition

Inspection Req distinguishes STAT (statutory inspection — pressure vessels, lifting equipment, and other assets with legally mandated inspection intervals), NON-STAT (planned maintenance without statutory requirement), Planned (scheduled PPM), and RTF (run-to-failure — assets where replacement is more cost-effective than maintenance). That four-way classification drives the maintenance planning entirely differently for each asset type.

Plant Condition — Good, Adequate, Poor — gives the condition assessment that capital planning decisions are made from. A facility with fifteen AHUs in Good condition and four in Poor condition is a facility with a capital replacement requirement in the planning queue. Without this field updated regularly, the facilities manager is making capital budget requests based on intuition rather than documented assessment.

Inspection Req set to STAT combined with Plant Condition set to Poor is the combination that triggers an urgent escalation to the client — that's a statutory inspection requirement on equipment that's already in poor condition, which is a safety and compliance risk rather than just a maintenance backlog item.

The location dropdown — twenty-four terminal zones across South Terminal, North Terminal, and NTX — pins each asset to its physical position without requiring a text description that varies by who entered it. ST Pier 2 means the same thing to every engineer on the team.

The barcode field connects physical asset tags to database records via scan — no manual lookup, no transcription error, no time spent hunting through the asset list to find the right record when you're standing in front of the plant.
