Building Defects and Forensic Building Services
When building defects surface after handover, the question shifts from delivery to evidence. Who is responsible. What caused it. What it will cost to put right. QBFS works through those questions with forensic site work, written defect reports that hold up in front of insurers and tribunals, and expert-witness services when matters head to determination or court.
What sits inside the defects pillar
Four distinct services, each with its own page:
- Post-completion defects — investigations into problems that show up after handover, from waterproofing failures to structural movement to non-conforming finishes
- Building defects report — the formal written report that sits behind every defect engagement, written for the audience that needs it (builder, owner, insurer, lawyer)
- Forensic building inspection — site-based evidence work for the harder cases, where root cause has to be proven rather than guessed
- Expert-witness work — independent reports and testimony for matters involving building defects, contract performance, or non-conformance disputes
All four work to the same methodology. Read the project record, walk the site, test the work against the contract and the standards, and write it up so the next decision can be made cleanly.
Why builders, owners, and lawyers use QBFS for defect work
The defects work needs three things at the same time: trade-level construction knowledge so you can see what actually happened, forensic discipline so the evidence holds, and written-report craft so the document does the job once it leaves the consultant's desk.
QBFS sits at that intersection. Paul has decades inside the build, plus a track record of producing reports that have stood up in determination and litigation. Reports are written in language a non-engineer can act on, which matters when an insurer is making a coverage call or a lawyer is briefing counsel.
The work is independent. QBFS is engaged by the party that needs the answer (builder, owner, developer, or legal team) and the report doesn't change to fit the brief.
When to engage QBFS on a defect matter
A few rules of thumb:
- As soon as a defect notification comes in. Early engagement means evidence is captured before site conditions change.
- Before a tribunal or court matter is filed. The strength of the case usually hinges on the quality of the inspection and the report, both of which benefit from time.
- If an insurer has questioned causation. A forensic report from QBFS gives the insurer's adjuster a clear evidence trail.
- If you're a builder and want an independent read. Builders sometimes engage QBFS to test their own position before a matter escalates. The report is just as honest either way.
How the defects work is delivered across Australia
The methodology travels. Site work runs wherever the property sits — Brisbane, Sydney, Melbourne, Perth, Adelaide, regional Queensland and northern NSW are common, with travel built into the engagement scope. Desktop review usually happens before the site visit, so the inspection time is spent on the right questions.
Reports follow Australian Standards, the NCC, and where relevant the local state's home-building or domestic-building legislation. For expert-witness work, reports follow the relevant court and expert-witness codes of conduct.

Common questions, answered.
- What counts as a building defect?
A building defect is a fault in the construction or materials that doesn’t meet the contract, the relevant Australian Standards, or the National Construction Code. Common examples include waterproofing failures, structural movement, non-conforming finishes, balcony water ingress, render cracking, drainage faults, and incorrect or missing fire and acoustic separation. QBFS investigates the underlying cause rather than just listing the symptoms.
- What is a building defects report?
A building defects report is the written output of a defect investigation. It identifies each defect, evidences the cause, names the responsible party where the evidence supports a view, references the relevant Australian Standards and NCC clauses, and proposes a rectification path. The report is structured so the audience that needs it — builder, owner, insurer, tribunal, court — can act on it directly.
- What does expert-witness work involve?
Expert-witness work is independent evidence for a legal matter. QBFS prepares an expert report following the relevant court’s expert-witness code of conduct, then makes the expert available for conferences with counsel, joint expert sessions, and giving evidence in chief and under cross-examination. Reports cover construction defects, contract performance, and non-conformance disputes.
- How long does the defects work take?
Each engagement is different. A targeted post-completion defect investigation can be reported in two to four weeks from the initial brief. Expert-witness work follows the matter’s timetable, with report drafting paced to the court’s directions. Complex multi-defect investigations or large commercial buildings can run longer; QBFS scopes the time upfront.
- Can QBFS act for either side in a dispute?
Yes. QBFS is engaged by the party that needs the work, and the report follows the evidence. That independence is part of why the reports stand up.
- What does the engagement cost?
The fee depends on the scope of the investigation, the number of defects, and whether the work includes expert-witness preparation. Call Paul on 0407 146 737 with the project details and a fee proposal follows the briefing call.
