How ESM Determinations Apply to Utilities, Transport, and Emergency Services

When a fire alarm fails in a busy train station or a smoke-control system breaks down in a hospital, the consequences are rarely limited to one building. Critical infrastructure like utilities, transport hubs, and emergency services depends on fire and life-safety systems that must perform reliably under pressure. In Victoria, the document that ties that performance to a clear maintenance routine is the maintenance determination.

A maintenance determination (MD) is a formal document prepared by a relevant building surveyor that specifies which essential safety measures (ESMs) a building must maintain, the level of performance they must achieve, and how often they must be inspected, tested, and maintained. For facilities that operate critical services, getting this right is not a paperwork exercise. It is a safety obligation.

What a maintenance determination actually does

In Victoria, an MD is required when an ESM is provided or altered by a building permit that does not need an occupancy permit, or by an emergency order or building order issued under Part 8 of the Building Act. It sets out three things:

• The specific ESM that is the subject of the determination.

• The level of performance the ESM must achieve to fulfil its purpose.

• The frequency and inspection type, testing, and maintenance required.

For buildings constructed before 1994 that have not been upgraded, a maintenance determination and schedule can also define the ongoing maintenance obligations. The document is issued by a registered building surveyor and must be kept with the building's records, alongside the annual essential safety measures report (AESMR).

Why this matters for critical infrastructure

Utilities, transport, and emergency services operate buildings where failure is not an option. A power station, a water treatment plant, a rail interchange, or a fire station all rely on systems such as fire detection, emergency lighting, smoke control, fire doors, and evacuation signage. When these are neglected, the risk is not just to the building itself, but to the people who depend on it.

Consider the consequences of an ESM failure in a transport hub. A smoke-control system that cannot pressurise corridors, or fire doors that do not close properly, can slow evacuation and put passengers at risk during an emergency. In a hospital or emergency services facility, a faulty alarm or an unmaintained backup system can delay response exactly when seconds count.

The link between determinations and maintenance schedules

A maintenance determination is closely tied to the maintenance schedule. The determination establishes what must be maintained and to what standard, while the schedule sets out the routine that keeps it in that condition. For many facilities, this means regular testing of fire alarms, inspection of emergency lighting, verification of fire doors, and servicing of smoke and detection systems.

These obligations do not disappear between annual reports. The Victorian Building Authority requires that records of all inspections, testing, and maintenance be kept, and that the annual report be prepared within 28 days of the anniversary of the occupancy permit or maintenance determination.

Where facilities commonly fall short

The most common failures are not dramatic system breakdowns, but quiet gaps in the maintenance routine. These include missing records, blocked exits, reactive maintenance instead of scheduled testing, and fire doors that are not checked or repaired. For critical infrastructure, these gaps are especially serious because the stakes are higher.

A signed annual report does not prove that equipment works. It only confirms that a report was completed. The value of a maintenance determination is that it forces the underlying question to be answered: is this system actually performing to the level required, and are we maintaining it often enough to guarantee that performance?

Who is responsible

Responsibility for ESM maintenance falls on the building owner, who must ensure that the measures identified in the maintenance determination are maintained in accordance with the specified requirements. For utilities, transport operators, and emergency services, this responsibility is often distributed across facilities teams, contractors, and specialist service providers. Clear records and defined accountability are essential to avoid gaps.

The wider safety picture

Regulators in Victoria have made clear that non-compliance with essential safety measure obligations can place occupants, passers-by, and adjoining properties at risk. For critical infrastructure, this risk extends beyond a single site. A failure in a transport hub can disrupt public services, while a failure in an emergency facility can compromise community safety.

This is why a maintenance determination in Victoria is more than a compliance formality. It is the mechanism that connects a building's design intent to its ongoing performance, ensuring that life-safety systems remain capable when they are needed most.

Final thoughts

For utilities, transport networks, and emergency services, essential safety measures are not optional extras. They are the systems that protect people during an emergency. Maintenance determinations give these facilities a clear framework for knowing what must be maintained, to what standard, and how often.
