Owners corporations & building managers
Plinth is the living maintenance plan. It shows a building exactly what every asset will cost, when it falls due, and whether the fund will cover it — and unlike the report in your drawer, it never goes stale.

The problem
Every owners corporation pays a quantity surveyor a few thousand dollars for a 10–20 year maintenance plan. It arrives as a static PDF, gets tabled at the AGM, and is filed. From that day it slowly drifts out of date — and most are only revisited every three to four years.
Goes stale immediately
Costs, conditions and timing move. The PDF doesn’t. By the next review it can be years wrong.
No live fund tracking
There’s no running view of actual spend against forecast, or whether the fund is still on track.
No link to the works
The plan never connects to the jobs actually done — so it can’t correct itself.
“We recommend that costs and sinking fund calculations be updated every 3 to 4 years… visual inspection… this report is not a certification, a warranty or guarantee.”— from a major quantity surveyor’s own maintenance plan, describing its product.
The proof · Riverbank Tower
$17m short
78-storey Southbank tower, 540 lots, six owners corporations. A standard quantity-surveyor plan forecasts $42,084,006of works and sets the fund to be “in balance”. On the same levy, the reserve falls $17m below the safety floor by 2036 — and needs to lift to about $2,482,500/yrto hold the plan. A filed PDF can’t show the owners corporation that; Plinth shows it in one screen, and keeps it current.

What Plinth does
Live, not laminated
Type in the current fund balance and the whole forward projection recomputes instantly — escalation, shortfall year and the levy needed, all at once.
balance → forecast → verdict, in real time
Cost escalation, visible
A $100k job today is $141k in ten years. Plinth shows the compounding instead of hiding it.
6 months to 10 years
Every horizon a manager needs — near-term operational and long-term capital, on one screen.
Major works on a timeline
Every big-ticket repair, when it falls due, escalated to the dollars of that year.
An open register
Edit any cost, add your own items, remove what doesn’t apply — it all recomputes live.
$750 a year, per account
Covers your account and first building; $350/yr each extra. No five-figure report, no quote form.
