Brisbane retaining walls plain-English terms

RPEQ: a Registered Professional Engineer of Queensland who can prepare or certify engineering design where the wall requires it.

Form 15: a Queensland design certificate commonly used to state that a design or system complies with the relevant requirements.

Agi pipe: slotted drainage pipe installed behind the wall to collect subsoil water and send it to an outlet.

Geofabric: filter cloth that separates soil from drainage gravel so fine material does not clog the drain.

How this is calculated

What this tool computes: checklist progress equals checked preparation items divided by the 13 listed items. The result is a readiness prompt, not a pass or fail decision.

What it does not compute: it does not decide whether approval is required, certify a design, quote the job or replace advice from a contractor, engineer, certifier or council.

Benchmark sources: Brisbane City Council retaining wall guidance, QBCC licence guidance and Queensland Development Code information.

Assumptions

The checklist assumes a Brisbane wall enquiry and helps organise site facts. It does not approve the wall, certify a design or confirm licence requirements for the exact contract.
