SPOILS by MAIN&FRANK
Before a building comes down, we work out what it's worth in pieces. The audit becomes a set of colour-coded drawings a contractor can price, and the materials leave site with somewhere to go. Concrete has a buyer. So do brick, hardwood, steel and most of what's bolted to the walls. The skip bin is what's left when nobody planned.
Construction and demolition waste is the country's largest waste stream, and it arrives in big sorted lots at known addresses. The problem is timing. Once the excavator is booked and the skip contract is signed, nobody re-plans the job around salvage. The audit has to land earlier than that.
of construction and demolition waste generated in Australia each year, more than all household waste combined
tonnes of that waste still ends up in landfill, most of it concrete, brick and timber with working markets

Demolition sites already talk in spray paint: services located, trees kept, walls marked for removal. We borrow the convention. Each material and fitting in the audit carries one of four colours, and the same code runs through the drawings and the inventory.
Reinstate
Straight back into the new build
The best pieces go directly into what you're building next. Hardwood floors, face brick, steel sections, stone. The new place starts with a history.
Store
Cleaned · catalogued · banked
Materials worth keeping but not needed yet are cleaned and catalogued, then held in the material bank until a later stage or another site wants them.
Sell
Money back against the demolition
Salvage-grade items with a market go to dealers and salvage yards. The proceeds come off the cost of the demolition.
Downcycle
Separated to spec · landfill last
What can't be reused gets separated for downcycling into soil, rubble, road base and energy. The skip bin is the last resort, not the plan.
Dashed line = to be removed. The oldest convention on a demolition drawing.
01
We measure, model and value the existing building. Every material, every fitting: what it is, what it's worth, where it can go.
02
Colour-coded demolition and recovery drawings your contractor can price and follow, plus the waste documentation your council asks for.
03
Materials routed to their destinations and documented on the way out. You keep the record, the value and the story.
The audit on its own. Find out what your building is worth in pieces before anyone swings at it.

Waste levies hurt and councils want plans. We solve the compliance problem, cut the tipping bill and give your knockdown a story worth telling.
Get value back from the house you're demolishing, then build the next one with pieces of it. The new place starts with a history.
Diversion numbers for the ESG report, material supply for the next site, and a defensible answer on demolition waste.
Your council already wants this.
Most councils require a Waste Management Plan before they'll approve a demolition. SPOILS is that plan, except this one pays for itself: levies avoided, salvage value returned, materials banked for the build.
Timing is the whole game, so we built a tool for it. The Demolition Map reads council planning portals, state application systems, tender registers and the trade press, and plots each demolition, strip-out or site clearance as a scored lead on a map of Australia. It refreshes every Monday at 6am Sydney time.
Leads surface at application or public-notice stage, weeks before demolition tenders close. That's when a recovery plan can still change the job.
Each lead carries a 0–100 score built from scale, waste volume, permit certainty and who's named on the job. A weatherboard teardown scores a 38. A tank farm scores a 93.
Rules-based estimates of what's in each building, with a confidence level per material and the same four marks as the audit. The assay starts before we've set foot on site.
The same tower shows up in a DA register, a tender notice and the trade press. We merge those into one record and keep every source link and weekly snapshot.
Book the assay before the excavator arrives. We'll tell you what the building is worth in pieces, and what it costs to find out.
