End-to-end scheduled maintenance solutions
Many generalist engineering firms treat electrical planning as a purely paper-based exercise. They draft switchboard designs and control schematics on computers in offices without visiting the physical plant floor. When independent contractors attempt to install these designs, they frequently discover physical spatial constraints, restricted access, or realise that the upgrades require twice as long as the plant’s allowed shutdown window. This disjointed planning leads to extended, revenue-draining offline periods and unsafe workarounds that fail regulatory audits.
MEX Engineering Group provides a complete, end-to-end industrial electrical planning solution. We lead with a maintenance-first reliability mindset, beginning with our customisable Service Level Agreements (SLAs). Our embedded industrial electricians build deep site memory, auditing your current load profiles, switchboard conditions, and cable routes first. By coordinating closely with your maintenance leads, we map out detailed project timelines, custom Motor Control Centre (MCC) layouts, and Low Voltage distribution schemes. This thorough planning guarantees that when we execute the installation, every wire, breaker, and PLC module fits perfectly and goes live precisely on schedule, with zero contractor handoff risk.
Our Customizable SLA approach
- Client-focused consultation: We meet directly with clients to understand their specific operational needs and challenges.
- Menu-based customization: We build custom packages ‘off a menu’ so you can choose the exact support required.
- Targeted scope: We only include services the client actually wants—no unnecessary add-ons or bloat.
- Tailored pricing: Pricing is tailored accordingly.

How we saved $17,000 per hour by reducing downtime
Our client’s plastic pallet washing facility is a critical piece of their supply chain infrastructure that runs 24/7. MEX Engineering Group was engaged to provide 24-hour operational assistance and critical preventative maintenance shifts to ensure the plant could survive the severe demands of continuous production.
By embedding a team of three maintenance electricians and one mechanical fitter, we organise all trades, source parts, and execute scheduled preventative repairs over four targeted weekend shifts. Since taking control of the preventative asset care on-site, unplanned downtime has decreased significantly. With client downtime valued at approximately $17,000 per hour, our engineered preventative maintenance strategy delivers considerable, measurable savings across their business operations.
Reliable electrical planning framework
We follow a structured 6-step framework to transition your electrical requirements from initial concept to safe, live plant integration:
Site capacity & demand analysis
We audit your existing power infrastructure, review as-built drawings, and log live current loads to establish a reliable baseline.
SLA integration & scheduling
We align your long-term planning needs under a customised Service Level Agreement (SLA) to schedule routine reviews on a predictable monthly budget.
System design & schematic CAD drafting
Our engineers compile precise, AS/NZS 3000 compliant CAD schematics, detailing all Low Voltage power routes and control panel specs.
Shutdown window optimisation
We break down the installation into micro-stages, pre-building panel components in our workshop to minimise on-site commissioning time.
In-house execution & wiring
Our full-time, licensed industrial electricians install the planned switchboards, route cables, and integrate controls safely on site.
Validation & compliance handoff
Providing reliable SLA options for non-full-time needs, embedding our tradespeople post-breakdown to stabilise daily operations, clear backlogs, and build deep site knowledge.

Frequently Asked Questions
How does a Service Level Agreement (SLA) support our electrical planning?
Historically, emergency electrical response has relied on informal, reactive phone calls, which exposes plants to unpredictable costs and delays. We solve this by formalising our support into subscription-based Service Level Agreements (SLAs). Instead of dealing with the constant friction of ‘do and charge’ billing, an SLA secures technical priority and dedicated resource planning for a predictable, fixed monthly fee. We build custom SLAs off a menu to meet your exact needs with guaranteed response times.
Why do facilities often underestimate the true cost of unplanned downtime?
Many operations managers look only at the direct cost of an electrician’s callout or a replacement part, ignoring the cascading financial losses of idle workers, disrupted downstream supply chains, and missed delivery targets. Unplanned outages from electrical failures can cost tens of thousands of dollars per hour. By scheduling routine preventative inspections and upgrades under a structured SLA, you actively protect your throughput and secure your long-term cash flow.
How does AS/NZS 3000 compliance affect electrical planning?
Under Australian law, all Persons Conducting a Business or Undertaking (PCBUs) must ensure their electrical installations are safe. AS/NZS 3000:2018 is divided into Part 1 (safety performance outcomes) and Part 2 (deemed-to-comply installation practices). When planning any electrical modification, our engineers design systems that meet both Part 1 and Part 2 standards, ensuring that any alterations or repairs are completely compliant and fully prepared for SafeWork audits.
Are your electrical maintenance services compliant with Australian Standards?
Absolutely. WYes. Every piece of work we execute is carried out strictly in accordance with AS/NZS 3000 (Wiring Rules), AS/NZS 3008, and NECA-backed safety regulations. Our in-house TÜV Nord-certified CMSE® professionals also ensure safety PLC logic and emergency stop loops are compliant with AS/NZS 4024.
Do you use subcontractors for your electrical maintenance?
No. While we maintain a robust network of industry partners, we deliver our core services using our own highly trained, full-time industrial electricians. This strict in-house engineering capability eliminates contractor handoff risks and ensures that your electrical safety is managed by technicians trained in our own dedicated facility.
