Modular Home Transport Damage: What to Do

If a module is damaged during delivery, make the area safe first. Record the damage when safe, notify the relevant project parties and insurer, and seek the required assessment before non-urgent repairs or further installation.

Do not assume the module must be replaced, or that it is safe to install. The next decision depends on the damage, contract, insurance and engineering advice.

Immediate response checklist

1. Step 01Protect people. Follow the site or transport operator's safety process. Contact emergency services or suitable professionals if there is an immediate hazard.
2. Step 02Record the condition when safe. Photograph the damage and surrounding area. Note the date, location and delivery stage. Do not delay necessary safety action to collect evidence.
3. Step 03Notify the relevant parties promptly. Contact the supplier, builder, transport operator and insurer or broker as appropriate. Keep a written record and obtain claim instructions.
4. Step 04Preserve the delivery records. Keep consignment notes, arrival photographs, condition reports and any comments recorded at handover.
5. Step 05Arrange assessment. Ask which engineer, inspector or certifier needs to review the module and proposed repair.
6. Step 06Confirm the next step in writing. Resolve repair approval, further movement, insurance instructions and installation checks before non-urgent work continues.

If emergency work is needed to prevent harm or further damage, record it as soon as practical. Follow professional and insurer instructions without assuming every cost will be recoverable.

Who is responsible for transport damage?

Review who arranged transport and the agreed transfer of risk. A supply-only purchase can differ from a supply-and-install contract. Loading, road transport, unloading and final placement may involve different parties.

Contracts matter, but they are not the only consideration. Applicable law, the cause of damage and insurance terms can also affect the outcome. A private clause cannot remove applicable consumer guarantees.

Use the builder and manufacturer responsibility guide to clarify reporting and investigation. Do not decide liability from the delivery stage alone.

Check transit insurance separately

Ask which policy covers the module during the actual journey. Construction cover may include transit, or it may require a separate policy or endorsement. Loading, lifting and storage can have different conditions.

A carrier's insurance certificate does not establish the module's full cover. Confirm the insured parties, limits, excess, exclusions and notification process with the insurer or broker.

Read the modular home insurance guide before modules leave the factory. After damage, follow the applicable claim instructions rather than guessing who will pay.

OSOM access: notice or permit?

OSOM means Oversize Overmass. The required road-access arrangements depend on the vehicle, load, route and jurisdiction. An eligible move may operate under a notice; another may need a permit.

NHVR's access guidance distinguishes notices from permits. Ask the operator to identify the arrangement covering your load and route. Confirm its conditions, including any travel, escort or road restrictions that apply.

For WA and NT, confirm requirements with the local transport authority. Do not assume an NHVR route approval covers those jurisdictions.

An access permission is not proof of insurance or a guarantee against damage. Route planning, load restraint and the loading method still need review by the responsible operator and professionals.

Review handling and route risks before delivery

• 01Load restraint: confirm the module's approved restraint and support requirements with the operator and supplier.
• 02Route clearances: review overhead obstacles, bridge restrictions and tight approaches for the actual loaded vehicle.
• 03Lifting: agree the lifting method, approved lifting points and responsible team.
• 04Site access: check ground conditions, unloading space and any exclusion area.
• 05Handover: record who receives the module and checks its arrival condition.

Use the delivery access checklist as a starting point. It does not replace the operator's route assessment or an engineered lifting plan where required.

Repair or replacement needs an assessment

Visible damage does not establish whether a module can be repaired. A qualified professional should assess the affected structure, weather protection, connections and other relevant parts.

Ask whether the repair changes the approved design or requires new engineering and inspection records. Confirm insurer instructions and contractual approval for the work. Keep the assessment and repair records for the final approval and handover process.

Do not accept an informal patch as proof that the home meets its requirements. Equally, do not promise replacement before the cause, repair options and legal or contractual obligations are assessed.

Agree the response before delivery day

1. Step 01Name the person responsible for the module at each delivery stage.
2. Step 02Confirm the notice or permit and route conditions for the actual movement.
3. Step 03Confirm insurance, claim contacts and any notification requirements.
4. Step 04Agree arrival inspections and condition-report records.
5. Step 05Define who authorises repair, further movement and installation after an incident.

These checks also help separate transport damage from defects found after handover. The warranty and defects guide explains the separate protections to check.

Frequently asked questions

Who is responsible if a modular home is damaged during transport in Australia?

Responsibility depends on the cause, project contracts and applicable law. Check who arranged transport and when risk transfers. Notify the relevant parties without assuming the factory, carrier or site builder is automatically liable.

Does insurance cover a modular home while it is being transported?

Do not assume cover. Ask the insurer or broker to confirm the module, journey, loading, unloading and storage arrangements. Cover may be included in construction insurance or need separate protection, subject to policy terms.

What should I do if a modular home is damaged in transit?

Make the area safe, record the damage when safe and notify the relevant project parties and insurer promptly. Keep delivery records. Seek the required professional assessment before non-urgent repairs or further installation.

Does every oversize modular delivery need an OSOM permit?

Not necessarily. An eligible movement may operate under a notice; another may require a permit. The operator must confirm the applicable load, vehicle, route and jurisdiction conditions before travel.

Does a damaged module always need replacement?

No conclusion should be assumed. Obtain a suitable professional assessment of the damage and repair options. Confirm insurance instructions, contractual decisions and any engineering or certification requirements before proceeding.

The bottom line

Prioritise safety, preserve evidence and notify promptly. Resolve the damage assessment and next steps in writing. Clear responsibility, access and insurance arrangements should be in place before delivery, not worked out after an incident.

Start your Planning Assessment for a proposed project. For an active delivery incident, contact the project parties, insurer and appropriate professionals directly.
