How Does Insurance Work During Construction?

Published 26 June 2026 · Last updated 26 June 2026

Quick Answer

Insurance during construction in Australia covers various risks like property damage, liability, and worker injuries. Key policies include Contract Works Insurance, Public Liability Insurance, and Workers' Compensation Insurance. Developers must ensure comprehensive coverage to protect against unforeseen events.

Insurance during construction is essential for managing the myriad risks that can arise on a project. In Australia, developers need to be aware of the specific types of insurance required to cover potential damages, liabilities, and worker-related incidents. The primary policies include Contract Works Insurance, Public Liability Insurance, and Workers' Compensation Insurance.

Contract Works Insurance is the backbone of construction insurance, covering risks such as damage to the property under construction from events like fire, storm, or theft. It also typically includes coverage for materials and equipment on site. Public Liability Insurance protects against claims for third-party injuries or property damage caused by construction activities. Workers' Compensation Insurance is mandatory, covering medical expenses and lost wages for employees injured on the job.

A common misconception is that standard home insurance or business insurance policies will suffice during construction phases. However, these are generally inadequate as they do not cover the specific risks associated with construction activities. Developers should ensure they have policies tailored to the construction industry to avoid substantial financial losses.

To see how this plays out, consider a developer working on a 10-unit residential project in Melbourne valued at $2.5 million. The developer secures Contract Works Insurance with a premium of $15,000, Public Liability Insurance for $5 million coverage at $8,000, and Workers' Compensation Insurance based on payroll. During construction, a severe storm causes $200,000 in damages to the site. The Contract Works Insurance covers these repairs, ensuring the project remains on schedule without additional financial burden.

In our experience reviewing thousands of properties across Australia, developers often overlook the need for periodic reviews of their insurance coverage as the project progresses. Changes in project scope, increased material costs, or extended timelines can affect the adequacy of existing coverage. Another frequent oversight is not confirming that subcontractors carry their own insurance, which can leave gaps in protection.

The answer can differ depending on your situation. For example, owner-builders might need different coverage compared to commercial developers. Projects involving heritage-listed buildings may require specialised insurance due to the unique risks involved. Additionally, developments in bushfire-prone areas might face higher premiums or specific requirements.

Given the complexity and potential financial impact of construction insurance, it's crucial to consult with a Chartered Quantity Surveyor and an experienced insurance broker. They can tailor your insurance package to your specific project needs, ensuring comprehensive coverage and compliance with all legal requirements.

  • Review your current insurance policies to ensure they include construction-specific coverage.
  • Consult with an insurance broker to explore comprehensive options tailored to your project.
  • Regularly update your insurance coverage as your project progresses and changes.
  • Verify that all subcontractors have adequate insurance in place.
  • Document all incidents and claims meticulously to support any insurance claims.
  • Engage a Chartered Quantity Surveyor to assess your project's risk profile and insurance needs.
