Independent Technical Opinion

Clear building evidence when the technical issues matter.

Building disputes often turn on technical questions: whether work is defective, whether practical completion has been achieved, what caused the failure, what standard applies, and what rectification is reasonable.

Led by Graeme Boyd, Registered Building Practitioner and qualified carpenter with more than 20 years’ construction, supervision, project management and compliance experience, BuildNex WA provides clear and methodical opinions supported by site observations, measurements, photographs, the National Construction Code, relevant Australian Standards and accepted construction practice.

Reports are prepared to assist with:

  • State Administrative Tribunal of Western Australia matters.
  • Pre-action dispute assessment and settlement discussions.
  • Insurance and loss-related building defect matters.
  • Builder, owner and developer technical disputes.
  • Independent review of another consultant’s report or rectification scope.

Engaged for real dispute scenarios, not generic inspections.
