Navigate Construction Disputes with Expert Witness Services
In the complex and dynamic world of construction, building disputes are inevitable. Whether it’s a disagreement over costs, quality of work, or project timelines, having an expert witness and dispute resolution specialist can be crucial in resolving these issues efficiently and fairly.
ACP Quantity Surveyors provides expert witness and dispute resolution services across NSW, Victoria and Queensland, helping clients resolve these challenges with independent cost evidence.
The Crucial Role of an Expert Witness
Disputed construction costs are one of the most common issues that require the involvement of an expert witness. However, several other scenarios can necessitate our services. Contractual disagreements often arise from the interpretation of contract terms and obligations, while conflicts related to the quality of workmanship can lead to significant disputes over the standard of construction work.
Additionally, delays and extensions of time claims frequently result in disagreements over project timelines and the justification for delays. In these and other common construction disputes, an expert witness plays a vital role in providing clarity and resolution.
Expert Witness Services in NSW, VIC and QLD
ACP provides construction expert witness reports for building disputes in New South Wales, Victoria and Queensland. These disputes are commonly heard by the NSW Civil and Administrative Tribunal (NCAT), the Victorian Civil and Administrative Tribunal (VCAT) and the Queensland Civil and Administrative Tribunal (QCAT), as well as the courts.
Each report sets out independent cost evidence a tribunal or court can rely on, whether the dispute involves defective work, an unfinished build or the value of variations. The findings are explained in plain terms, so every party can follow how each figure was reached.
Most of ACP’s reporting is now prepared remotely, but expert witness work is the exception. Where a dispute calls for it, director Michael Sturgess inspects the site in person, including interstate.
Key Qualifications of an Effective Expert Witness
An effective expert witness must possess a unique set of skills and qualifications. Technical expertise is essential, as it ensures a deep understanding of construction processes, materials, and methodologies. Familiarity with industry standards and codes of conduct is also crucial, allowing the expert to provide insights that align with established practices.
Not only this, but the ability to present clear, concise, and unbiased evidence is paramount, whether in written reports or oral testimony. Experience in presenting evidence to the appropriate courts or tribunals is also necessary, ensuring that the information is communicated effectively and professionally.

Frequently Asked Questions
Do you provide expert witness reports outside NSW?
ACP prepares construction expert witness reports for disputes in New South Wales, Victoria and Queensland. Where a matter needs a site inspection, Michael Sturgess attends in person, including interstate.
Can an expert witness report be prepared before a dispute reaches a tribunal?
A report can be prepared at any stage, including during early negotiations between the parties. Independent cost evidence at that point often helps narrow the issues before a formal hearing.
What types of construction disputes need an expert witness?
Expert witnesses are commonly engaged for disputed construction costs, defective or incomplete work, variation claims and delays to the build. In each case, the report gives the tribunal or court an independent view of the costs involved.
What information do you need to prepare an expert witness report?
The building contract, plans, invoices, progress claims and any correspondence about the dispute help the quantity surveyor assess the matter accurately. ACP reviews these documents first and confirms the scope and fee before any work begins.
Is an expert witness independent of the party that engages them?
An expert witness owes their duty to the tribunal or court, not to the party paying for the report. ACP's findings are based on the evidence and the costs, whichever side of the dispute engages us.
