Electrical assessments that tell you what's really there
Capacity audits, condition assessments, and compliance gap analysis — engineering rigour for due diligence.
An existing building's electrical infrastructure is rarely what the drawings say. Loads change over decades. Switchboards get modified. Capacity that looked adequate at design stage gets consumed by tenant fitouts, equipment upgrades, and ad-hoc additions. When a building changes hands, gets extended, or is converted to a new use, the question is: can the existing electrical infrastructure handle it?
MRGN's electrical capacity and condition assessments answer that question with engineering rigour. We audit the existing installation against available documentation, inspect the key assets, analyse actual load data where available, and produce a report that a lender, insurer, or planning authority can rely on.
What our reports include
- Measured vs. design capacity — we quantify actual headroom, not theoretical
- Condition grading — each major asset rated by condition and remaining service life
- Compliance gaps — items that don't meet current AS/NZS 3000 or relevant standards
- Risk register — ranked by consequence and likelihood
- Recommendations with order-of-magnitude cost estimates — so you can prioritise
Typical assessment scope includes main switchboards, distribution boards, main cabling, generators, UPS systems where present, and major mechanical services switchboards. We can also include EV charging readiness assessment — see our EVSE & BESS feasibility service.
While this is an electrical assessment, MRGN's multi-disciplinary capability means we understand how the electrical infrastructure serves the broader building — mechanical plant loads, fire service supplies, hydraulic pump requirements, and lift power demands. The report accounts for these interdependencies, not just the electrical installation in isolation. See our full design offering.
Frequently Asked Questions
- When do I need an engineering assessment rather than just a sparky check?
- Electricians test safety and compliance. An engineering assessment goes further: it analyses the upstream network, calculates actual vs. design load, identifies constraints that can't be seen from a visual inspection, and quantifies residual capacity for future loads.
- How long does an assessment take?
- A typical commercial building assessment takes 2–3 weeks from engagement to final report, depending on building size and documentation availability.
- Do you cover regional Victoria?
- Yes. We service metropolitan Melbourne and regional Victoria.
- Can the assessment be used for finance or insurance purposes?
- Yes. Our reports are prepared by a qualified engineer and suitable for due diligence, lender requirements, and insurance risk assessment.
- What's the difference between a condition assessment and a compliance audit?
- A condition assessment tells you what's there and what state it's in. A compliance audit compares the installation against current standards. Our assessments include both, plus the capacity analysis.
