Electrical Design & Drafting
JMB Engineering delivers full electrical design and drafting services, from concept studies and feasibility through to detailed design packages ready for construction. We support projects across data centres, renewables, water infrastructure, mining and heavy industry — from greenfield builds to brownfield upgrades.
Our design team produces drawing packages to Australian standards, covering everything from high-voltage switchroom designs and underground mining electrical reticulation through to data centre power distribution, renewable energy connection design, and control system documentation.
What We Deliver
- Concept and feasibility electrical design
- Detailed electrical design packages
- Single-line diagrams and schematic drawings
- Cable schedules and cable routing designs
- Equipment specifications and datasheets
- Switchboard and MCC design
- Control system functional specifications
- PLC design and PLC I/O listings
- Instrumentation and control system design
- Hazardous area classification and documentation
- Electrical layout and general arrangement drawings
- As-built documentation and redline markups
- Standards compliance reviews (AS/NZS 3000, AS/NZS 3007, MDG series)
Sectors We Support
Our electrical design and drafting is delivered across a broad range of industries: data centres (power distribution, switchroom and reticulation design), renewable energy (solar, wind and battery storage connection and reticulation design), water infrastructure (treatment plants, pump stations and pipelines), coal mining (underground and surface, NSW and Queensland), metalliferous and hard-rock mining, and utilities, gas and heavy industry.
Design packages are backed by our in-house power system studies and protection engineering capability — so your design is verified for fault level, protection and load flow before it reaches site.
Frequently Asked Questions
What does electrical design and drafting cover?
It covers the full electrical design package — switchboard design, control systems, PLC and instrumentation, hazardous area classification, cable sizing, single-line diagrams and construction-ready drawings — to AS/NZS standards.
Do you design for data centres and renewables?
Yes. We design electrical systems for data centres, renewable projects (solar, wind, BESS), water treatment, mining and heavy industry, tailoring redundancy and reliability to each sector’s requirements.
Which CAD and design standards do you work to?
All design is delivered to AS/NZS 3000 and relevant sector standards, with drafting in industry-standard CAD, coordinated with power system modelling so the design is verified, not just drawn.
Can you take a project from concept to construction?
Yes. We deliver from concept and feasibility through detailed design, drafting and construction documentation, with the modelling and protection work integrated so the design is engineering-verified end to end.
All design work is reviewed by experienced chartered engineers and delivered to a standard suitable for regulatory submission and construction. Contact JMB Engineering to discuss your electrical design and drafting needs.
