When close-out becomes
a dispute.
Not every defect is caught in time. When a close-out turns into a claim — at NCAT, in court, or across the negotiating table — the side with the clearest independent evidence wins. Group 4 provides that evidence: expert defect inspection, quantification, causation and rectification-cost reporting, built on the same documented method that prevents disputes in the first place.
Home Building Act claims
Owners or owners corporations pursuing a builder over major or minor defects inside the six- and two-year statutory warranty windows.
NCAT & court proceedings
Defect disputes before the NSW Civil and Administrative Tribunal or the courts, where independent expert evidence carries the day.
Contractual & DLP disputes
Practical completion, defect liability period and final-account disagreements between developer, head contractor and trades.
Building bond & insurance
Strata building bond disputes over defect scope and cost, and defect claims under insurance or the statutory schemes.
Evidence, not opinion.
- Independent defect inspection — a structured, photographed inspection to a defined standard, not a walk-through and a view.
- Defect quantification & causation — each item located, categorised (major vs other under the Home Building Act), and assessed for cause, not just presence.
- Rectification scope & cost — a cost-coded schedule of what it takes to make good, defensible line by line.
- The expert report — a clear, written report prepared to the applicable expert code of conduct, with the detail behind it available for scrutiny.
- The defensible file — every inspection time-stamped and photographed, so the evidence holds up under cross-examination.
The method was always
a body of evidence.
Group 4's day-to-day work — the cost-coded register, the staged inspections, the reinspection discipline, the documented sign-off — produces exactly what a dispute needs: an independent, contemporaneous, defensible record. The same rigour that keeps a project out of a dispute is what wins one.
- Independent by definition. Engaged for one party's outcome, but the duty in expert evidence is to the tribunal or court first — and Group 4 works accordingly.
- Specialist, not general. Defects and close-out are the whole practice, not a sideline to a broader consultancy.
- Twenty years of tier-one delivery behind every assessment of what is a defect, what caused it, and what it costs to make right.
