Your numbers, not ours
Work out a planning allowance for your wall
Supply the dimensions and a rate you already have from a quote, a quantity surveyor or your own research. The tool does the multiplication; it does not supply a Geelong price.
Why no Geelong rate is published
Method: how this retaining wall Geelong allowance is calculated
Wall length times average exposed height times a rate gives a face-area figure, and the buffer widens it into a range. That arithmetic is deliberately all this tool does. Publishing a fixed Greater Geelong square-metre number would hide how much the true figure moves once the site is actually looked at, so the rate has to come from you: a written quote already in hand, a quantity surveyor, or a conversation with a contractor.
Two walls with an identical face area can carry very different totals. A driveway, parked vehicles, a pool, a shed or steep upper ground sitting above the wall changes the design loads before a material is chosen. Demolition of an old structure, excavation in tight ground, post or footing depth, and a full drainage system, filter fabric (a permeable membrane that keeps soil out of the drainage layer), aggregate and a lawful outlet, are usually priced separately from the visible face.
Access changes the number again. A narrow side gate, an established Geelong West lot, or a steep growth-area boundary can restrict machinery, slow material delivery and add spoil-removal cost that a flat per-square-metre rate never captured in the first place.
Use the allowance as an opening figure, then compare written quotes on dimensions, demolition, excavation, posts or footings, drainage, engineering, permits, finish, access assumptions and exclusions, not on the headline rate alone. Consumer Affairs Victoria sets out what a written building contract should cover.
