Building inspections by competent persons and cadets

This information relates to the inspection of stages for single, detached class 1a buildings.

Competent persons

A competent person is a person who a building certifier decides is competent to help inspect an aspect of a stage of building work.

See Part 5 of the Building Regulation 2006 for the requirements for competency.

Cadets

A cadet is a person appointed to help a building certifier perform building certifying functions.

They are usually:

  • employed by a local government or private certifier
  • completing studies to become licensed as a building certifier.

Cadets are not licensed and can only help building certifiers assess and inspect building work under supervision.

If a cadet is employed by a local government or private certifier, they can't be used as a competent person by these employers.

However, a building certifier from one organisation may use a cadet from another organisation if the cadet meets the regulation requirements.

Cadastral surveyors

If a building certifier relies on inspection help for the siting of a building, the competent person must be a cadastral surveyor.

Inspections for Class 1a and 10 buildings

Footing stage

A building certifier can rely on a suitably qualified competent person to help inspect aspects of the footing stage for single detached class 1a buildings.

However, for aspects relating to boundary clearances and reinforcing steel in the footing system, the competent person must be a cadastral surveyor and registered professional engineer.

The building certifier must sign the inspection certificate for the footing stage, even if they rely on a competent person for all aspects.

Final stage

A building certifier must conduct an inspection for the final stage. A competent person can inspect some, but not all, aspects of the final stage.

Certificates

The competent person must give the building certifier a Form 16—Inspection certificate/aspect certificate/QBCC licensee aspect certificate (PDF, 158KB) for work they complete so the building certifier can confirm a stage is complete.

To certify a stage, a building certifier needs certificates for all the relevant aspects that make up the stage.
