Retaining wall scope calculator

Calculate face area, then record the access, drainage, surcharge and approval inputs a real quote still needs.

Retaining walls Canberra: what the number leaves out

Face area is only a starting dimension. A quote also considers system, excavation, post holes or footing, access, spoil handling, drainage, surcharge, corners, steps, demolition, engineering, approvals and reinstatement.

How this is calculated: method, assumptions and sources

The tool multiplies entered length by average retained height. It does not apply a dollar rate because a site-unseen rate would imply false precision. For approvals, consult ACT Planning BA guidance, DA guidance and City Services stormwater guidance.

Next step

Send the dimensions with photos, suburb, access, drainage symptoms and what sits above the wall for a site-specific scope.
