Industrial and warehouse buildings in Australia — encompassing manufacturing plants, logistics distribution centres, cold storage facilities, and food processing factories — have MEP (Mechanical, Electrical, and Plumbing) requirements that differ fundamentally from commercial and residential construction. Large-volume spaces, process-specific ventilation, high electrical loads for machinery, and specialised drainage systems all demand industrial MEP drafting expertise. A poorly coordinated industrial MEP design can halt production lines, fail WorkSafe audits, and cost hundreds of thousands in unplanned downtime.
This guide covers MEP drafting requirements for Australian industrial and warehouse buildings, including large-volume ventilation, process cooling, high-power electrical distribution, industrial hydraulics, and compliance with WorkSafe regulations and NCC 2022. Whether you are a mechanical contractor, industrial developer, or process engineer, this resource will help you specify and coordinate MEP services for industrial facilities across Australia.

Ventilation and Mechanical Systems
Large-Volume Space Ventilation
Industrial buildings with clear heights of 8–15 metres and floor areas of 5,000–50,000 m² present unique ventilation challenges. The HVAC mechanical drafting must address thermal stratification (hot air at roof level, cold air at floor level), smoke exhaust for fire safety, and general dilution ventilation for occupant comfort. Solutions documented in MEP drawings include high-volume low-speed (HVLS) ceiling fans, ridge ventilators, wall-mounted supply and exhaust fans, and destratification ductwork.
Process Exhaust and Dust Extraction
Manufacturing facilities require dedicated exhaust systems for process fumes, welding smoke, paint spray booths, dust extraction (woodworking, metalworking), and chemical vapours. Each system must be designed to Workplace Health and Safety (WHS) exposure standards, with MEP documentation showing capture velocities at source, duct velocities to prevent settling (typically 15–20 m/s for dust), cyclone or baghouse filter specifications, and discharge locations compliant with EPA requirements.
Cold Storage Refrigeration
Cold storage and freezer facilities (operating at -25°C to +4°C) require specialist MEP design including refrigeration plant rooms (ammonia or synthetic refrigerant systems), insulated panel envelope coordination, floor heating (to prevent frost heave in freezer floors), condensation management at dock doors and temperature transition zones, and emergency ventilation for ammonia leak scenarios compliant with AS 1210 and AS 4674.
Industrial Electrical Systems
High-Power Distribution
Industrial facilities typically require significantly higher electrical capacity than commercial buildings. A mid-sized manufacturing plant may have a 2–5 MVA transformer supply feeding motor control centres (MCCs), variable speed drives (VSDs), process controllers, and general power distribution. Electrical drafting must document single-line diagrams showing transformer, main switchboard, MCC arrangements, power factor correction, and harmonic filtering — all compliant with AS/NZS 3000 and the local distribution network service provider (DNSP) requirements.
Hazardous Area Classification
Facilities handling flammable gases, vapours, or combustible dusts require hazardous area classification compliant with AS/NZS 60079. MEP electrical drafting must document zone boundaries (Zone 0, 1, 2 for gases; Zone 20, 21, 22 for dusts), specify explosion-proof (Ex-rated) equipment within each zone, and detail earthing and bonding arrangements to prevent ignition sources. This specialist documentation is critical for paint shops, chemical storage, grain handling, and pharmaceutical manufacturing facilities.
Emergency and Essential Services
Industrial buildings require emergency lighting (AS 2293), fire detection and alarm systems, and often essential power supply for process equipment that cannot tolerate power interruption. MEP documentation must show generator sizing and connection, UPS systems for critical process controllers, and automatic transfer switch (ATS) arrangements coordinated with the overall MEP design.
Industrial Hydraulic Services
Process Water and Drainage
Hydraulic drafting for industrial facilities covers process water supply (volume and pressure requirements for manufacturing), trade waste drainage (chemical neutralisation, oil separation, solids settlement), floor drainage in washdown areas (minimum 1:100 falls per AS/NZS 3500), and stormwater management for large roof and hardstand areas. Food processing facilities additionally require potable water treatment, clean-in-place (CIP) systems, and HACCP-compliant drainage arrangements.
Compressed Air Systems
Many industrial facilities require reticulated compressed air for pneumatic tools, process automation, and packaging equipment. While compressed air is typically a mechanical/process engineering scope item, MEP drafting must coordinate air compressor locations, receiver tanks, distribution pipe routing, and electrical supply to compressor motors within the overall services coordination model.
Fire Protection
Large industrial buildings require extensive fire sprinkler systems (AS 2118) often with Extra Hazard classifications requiring higher water density and larger pipe sizes than commercial buildings. MEP drafting documents sprinkler layout, fire pump room design, suction tank or town main assessment, hydrant and hose reel locations, and any specialist systems (foam for flammable liquid storage, deluge for high-risk areas). BIM coordination ensures sprinkler pipework routes do not conflict with overhead cranes, racking systems, or process equipment.
BIM for Industrial MEP
| BIM Application | Industrial Benefit |
|---|---|
| Clash detection | Identify conflicts between MEP services and overhead cranes, racking, and process equipment |
| Services routing | Optimise pipe and duct routes in large-span structures with limited mounting points |
| Quantity extraction | Accurate material take-offs for large-scale industrial pipe and duct runs |
| Maintenance planning | Embed asset data for preventive maintenance scheduling |
| Expansion planning | Model future equipment locations and services provisions |
For industrial refurbishment and expansion projects, Scan to BIM services capture existing services and equipment arrangements that may not match original as-built documentation, providing an accurate baseline for new MEP design work.

Frequently Asked Questions
What ventilation standards apply to Australian warehouses?
Australian warehouses must comply with AS 1668.2 for general ventilation, NCC 2022 for smoke hazard management, and WHS Regulations for workplace exposure standards. Large warehouses typically use a combination of natural ventilation (ridge vents, wall louvres) and mechanical ventilation (exhaust fans, HVLS fans) to manage temperature and air quality.
How is cold storage MEP different from standard warehouse MEP?
Cold storage facilities require refrigeration plant design (ammonia or synthetic systems), insulated panel envelope coordination, floor heating to prevent frost heave, condensation management at temperature transition zones, emergency ventilation for refrigerant leak scenarios, and specialist electrical design for low-temperature environments. These requirements significantly increase MEP complexity compared to ambient-temperature warehouses.
What electrical capacity does a typical manufacturing plant need?
Electrical capacity varies widely based on manufacturing processes. Light manufacturing (assembly, packaging) may require 100–500 kVA, while heavy manufacturing (metal processing, injection moulding) can require 2–10 MVA or more. MEP electrical drafting must include load schedules, power factor analysis, and coordination with the local DNSP for supply upgrades.
Do industrial buildings need BIM coordination?
BIM coordination is particularly valuable for industrial buildings where MEP services must coordinate with overhead cranes, process equipment, racking systems, and goods vehicle circulation. While industrial ceiling spaces are typically larger than commercial buildings, the services density and equipment interfaces create unique coordination challenges best resolved in a 3D model.
What fire sprinkler classification applies to warehouses?
Most Australian warehouses require Ordinary Hazard Group 3 (OH3) or Extra Hazard Group 1 (EH1) sprinkler classifications under AS 2118, depending on storage height, commodity type, and racking configuration. High-rack storage may require in-rack sprinklers. The classification directly affects pipe sizing, water supply requirements, and fire pump capacity — all documented in the MEP fire services drawings.
How does MEP drafting address hazardous areas?
Hazardous area classification (AS/NZS 60079) requires MEP electrical drafting to define zone boundaries on layout drawings, specify Ex-rated equipment within each zone, detail earthing and bonding arrangements, and coordinate with mechanical ventilation design that may reduce zone extent. This specialist documentation requires experience with industrial process safety standards.
