Thinking about buying a mining dongas in WA? Good call.

But before you go slapping one on site, there’s a bit to sort out. Getting it delivered, set up, and signed off isn’t always straightforward. You’ve got logistics to think about, site prep to get right, and laws you’ve actually got to follow. Stuff it up, and you’ll waste time and cash.

This guide breaks down what you need to know so your portable dongas shows up, gets installed, and passes muster without the added drama.

Delivery Considerations

1. Transport Method Depends on the Size

• Small to mid-size dongas: Usually delivered using tilt trays or HIAB trucks.
• Larger units or modular setups: Need low-loaders and sometimes pilot vehicles.
• Wide loads: Will require permits under WA road transport rules. Main Roads WA has specific guidelines for oversize loads.

2. Access Roads and Site Location

• Does your site have sealed roads or red dirt tracks?
• Some remote or regional areas become inaccessible during the wet season (we’ll plan around it).
• Make sure the drop zone has enough clearance for the truck to swing in, set down, and leave safely.

3. Timing and Lead Time

• Lead times vary depending on stock, distance, and transport availability.
• Allow extra time for remote areas like the Pilbara or Kimberley (since our dongas are constructed and stored in Perth)
• Weather delays are more common than you think. A storm up north can easily push the whole week’s delivery back a few business days.

 Site Setup Requirements

 

1. Concrete Footings Are (almost always) Needed

The need for footings depends on a few factors:

• Soil type and compaction
• Building size and layout
• Wind classification (especially in cyclone zones)
• Long-term vs short-term install

That said, 99% of the time, footings will be required. Not just for compliance — but to keep your donga stable, level, and safe over time. Footings help prevent movement, reduce stress on the frame, and make sure the structure performs the way it’s meant to.

At Instant Transportable Offices, the final call always comes from a qualified structural engineer to meet NCC requirements and site-specific conditions.

2. Cyclonic vs. Non-Cyclonic Setup

Where your donga is going in WA makes a big difference to how it needs to be built and installed. If you’re setting up in a cyclonic zone (especially in parts of the Pilbara or the north coast) your setup needs to be tougher, heavier, and engineered to hold its ground.

Cyclonic Zones (Region C & D)

These areas can see winds hitting up to 288 km/h, so your building needs serious reinforcement:

• Cyclonic-rated concrete footings are a must. At Instant Transportable Offices, ours weigh up to 4750 kg and are engineered to handle these extreme conditions.
• You’ll also need custom tie-down systems, reinforced frames, and stronger roof connections to keep everything locked together.
• Positioning matters too. Buildings need to be strategically placed and anchored to reduce exposure to prevailing winds and flying debris.

All of this is designed and signed off by structural engineers to meet the standards in AS/NZS 1170.2:2021 and the National Construction Code.

Non-Cyclonic Zones (A & B)

In places like Perth Metro (Region A) where wind isn’t as extreme, the requirements ease up:

• Standard footings are still recommended for stability, but they don’t need the same level of reinforcement.
• Tie-downs are simpler, and overall building materials don’t need to be as heavy-duty.

3. Utilities and Services Setup

Power, water, and waste connections are essential for any donga to be functional — and these services must be installed correctly and legally to ensure compliance and long-term reliability.

• Electrical: All power connections must be carried out by a licensed electrician, whether connecting to mains power, generators, or solar systems. Units are typically delivered with pre-installed distribution boards, making final hookup straightforward for qualified trades.
• Plumbing: A licensed plumber is required to connect water supply and manage wastewater systems. This includes linking to mains, site tanks, or pressure systems, and ensuring proper drainage via holding tanks, leach drains, or an existing sewer connection.
• Waste Management: Depending on the location and unit type, different waste solutions may apply — all of which need to comply with WA health and plumbing codes.

At Instant Transportable Offices, we coordinate all of this for you. Our team ensures each installation is handled by qualified professionals, meeting all necessary standards and regulations. You can be confident everything is done by the book.

Compliance & Regulations in WA

1. Local Council Approvals & Planning

Most shires and councils across WA require you to submit an application before installing any transportable or temporary building — especially if it’s being used for accommodation or stays in place longer than a few weeks.

• Development approval or building permit may be required, depending on zoning and land use.
• Councils may ask for structural drawings, site plans, engineer certifications, and fire safety documentation (which we can all supply).

2. National Construction Code (NCC) Compliance

All buildings — even temporary or transportable ones — must comply with the National Construction Code (NCC), including:

• Structural integrity
• Energy efficiency (Section J)
• Fire safety
• Liveability standards, especially for accommodation use

Instant Transportable Offices build every unit in line with the NCC as standard, so it’s not something to worry about. If you need custom inclusions for a particular site or industry, those can usually be engineered in.

3. Work Health & Safety (WHS) Regulations

For any commercial or mining site, your dongas also need to meet WHS Act 2020 (WA) requirements. This includes:

• Safe access (stairs, landings, ramps where required)
• Secure anchoring (especially in cyclone zones)
• Adequate ventilation, lighting, and emergency egress
• Proper setup of utilities to prevent fire, injury, or contamination risks

Failing to meet WHS standards can get your site shut down. Therefore, it’s critical that everything’s installed by qualified professionals and signed off properly.

4. Cyclone, Bushfire, and Environmental Ratings

Your region determines additional compliance steps:

• Cyclone Zones: Need engineered tie-down systems and cyclone-rated construction (see earlier section).
• Bushfire-Prone Areas: May require compliance with BAL (Bushfire Attack Level) assessments.
• Remote or Heritage Zones: Could involve environmental or Aboriginal heritage clearances (especially in regional WA).
