Expert Witness Services

Independent expert opinion for building code, access, defect and incident matters

We assist solicitors, insurers, owners, builders, consultants and project teams with clear, evidence-based technical opinions across disputes, investigations and regulatory matters.

Independent technical advice for complex building matters

Expert evidence is most useful when the issues are technical, the compliance pathway is unclear, or the facts need to be assessed against the BCA, relevant Australian Standards and accepted building practice.

ATLR provides independent expert advice in relation to technical disputes, defect matters, injury-related incidents and project-specific building regulatory issues. Our role is to provide clear, reasoned opinions within our area of expertise, based on the available evidence, relevant codes and standards, and project-specific circumstances.

Independent, objective and evidence-based

  • ATLR’s role as an expert is to provide independent technical opinion, not advocacy.

    Our opinions are based on the relevant code and regulatory framework, the available evidence, site conditions and the specific issues in dispute. We understand the importance of clear reasoning, careful documentation and opinions that are practical, defensible and appropriately scoped.

    This is a natural expansion of the wording already used on the current Expert Witness page, which emphasises independent expert advice and clear expert opinions
