Do You Need a Capital Works Forecast, and How Do You Build One?

Every self-managed scheme eventually hits the same wall: the roof is getting old, the driveway is cracking, the lift hasn't been touched in fifteen years, and nobody can say with any confidence whether the capital works fund will actually cover it when the time comes. A capital works forecast is the document that answers that question before it becomes a crisis. It's not exotic — you don't need a $3,000 consultant's report to get a workable one for a small scheme — but it does need to be done properly, because it's the single input that turns "we hope the fund is enough" into "we know the fund is enough, and here's the levy that keeps it that way."

What a capital works forecast actually is

A capital works forecast (also called a sinking fund forecast, reserve fund plan, or maintenance plan depending on your state) is a schedule that:

1. Lists every major asset the scheme is responsible for — roof, render, driveways, lifts, pool equipment, fencing, common-area fixtures.
2. Estimates each asset's remaining useful life — how many years until it needs replacing or major work.
3. Estimates the cost of that future work, in today's dollars (and often inflated forward).
4. Spreads the total cost across the years so the fund holds enough, at the right time, without a single huge spike in levies.

The output is usually a year-by-year table: what work is expected, roughly when, roughly what it will cost, and what the fund balance and required annual contribution look like across the forecast period (commonly 10 years, sometimes longer).

Why it matters

• It sets the levy, not guesswork. Without a forecast, the capital works levy is usually set by "whatever we did last year plus a bit" — which drifts away from what the fund actually needs.
• It prevents special-levy shocks. A scheme that's been under-contributing for a decade discovers the gap all at once, right when the roof actually fails, and the fix is an unbudgeted five-figure special levy landing on every owner at once.
• It's often a legal requirement, not an optional planning nicety — see the callouts below.
• It protects lot values. Buyers' conveyancers routinely check the capital works fund balance and forecast during a strata search; a healthy, funded forecast is a quiet selling point, and an absent or hollow one is a red flag that shows up in negotiations.

What the forecast needs to cover

At minimum, a usable forecast for a small self-managed scheme should identify:

• Every major common-property asset with a finite life: roof covering, external paint, driveways/paths, fencing, lift(s) and lift components, pumps and shared plant, common-area flooring, guttering, waterproofing membranes, pool/spa equipment if applicable.
• Current condition and estimated remaining life of each — a rough visual assessment is enough for a small scheme; a professional building condition report is worth it for larger or older buildings, or where structural issues are suspected.
• Estimated replacement or major-works cost, in current dollars, ideally with a note on how the estimate was reached (a contractor quote, a rule-of-thumb rate per square metre, a previous invoice adjusted for time).
• The year the work is expected to fall due.
• The fund's current balance and expected income (the annual capital works levy), rolled forward year by year against the expected spending, so you can see whether the balance ever goes negative under the plan.

How to build one without hiring a consultant

For a modest self-managed scheme, this is genuinely a spreadsheet exercise, done properly:

Step 1: Walk the property and list the assets

Physically walk the common property with a committee member who knows the building, and list every shared asset with a finite life. Don't forget the unglamorous ones — guttering, external paint, fencing, driveway seal — that get forgotten until they fail.

Step 2: Estimate remaining life and cost for each

• For assets recently installed or replaced, use the manufacturer's or industry's typical lifespan (roofs, paint and driveway surfaces all have well-known ranges).
• For assets of unknown age or condition, get a tradesperson's opinion while they're on-site for something else, or commission a proper condition assessment if the building is older or the stakes are high (lifts, structural items).
• Use recent quotes, past invoices adjusted for time, or a per-square-metre industry rate for the cost estimate. It doesn't need to be precise to the dollar — it needs to be defensible and not wildly optimistic.

Step 3: Lay it out year by year

Build a simple table: year, expected work, estimated cost, running fund balance (opening balance + levy income − spending). Extend it 10 years (or whatever period your state expects — see below).

Step 4: Solve for the levy

Adjust the annual capital works levy until the running balance never goes negative across the forecast period, ideally with some buffer for cost overruns and bring-forward of unexpected work. This is the number the AGM actually needs to approve.

Step 5: Revisit it every year

A forecast built once and never touched again drifts out of date fast — costs inflate, assets age faster or slower than expected, and unplanned work happens. Review and roll the forecast forward at each AGM, adjusting the levy as needed.

Legal requirements differ by state

Whether a capital works forecast is compulsory, how far forward it must run, and how often it must be reviewed, is set by your state's legislation:

South Australia, Tasmania, the ACT and the Northern Territory each have their own sinking or reserve fund provisions with varying degrees of prescribed forecasting detail — confirm the current requirement for your scheme before relying on this guide alone.

Common mistakes

1. Treating the forecast as a one-off document

A forecast written once at registration and never revisited is worse than useless — it gives false confidence while quietly going stale.

2. Underestimating costs to keep the levy politically comfortable

A forecast built to justify a levy the committee already wants, rather than one built from honest asset estimates, just delays the reckoning and makes the eventual correction bigger.

3. Ignoring assets that "haven't failed yet"

Guttering, seals, and paint don't send a warning before they fail — they just fail. If it's a shared asset with a finite life, it belongs in the forecast even if it looks fine today.

4. Forgetting inflation

A cost estimated in today's dollars for work expected in year eight will cost more by the time it's actually due. Build in a reasonable allowance rather than assuming today's quote holds forever.

Frequently asked questions

Do we legally have to have a capital works forecast?

In several states, yes, at least once the scheme crosses a size threshold — see the callouts above for your jurisdiction. Even where it isn't strictly compulsory, not having one is a significant risk for the committee and for owners relying on an accurate strata search.

How far ahead should the forecast run?

Ten years is the common standard and matches the explicit requirement in states like NSW. Some committees run a shorter, more detailed near-term plan (three to five years) nested inside a longer, rougher ten-year view.

What if the fund is already behind where the forecast says it should be?

Raise the annual capital works levy to close the gap over a realistic period, and consider whether any near-term work genuinely needs a special levy to bridge the shortfall rather than waiting for the ongoing levy to catch up.

Can we build this ourselves, or do we need a professional?

For a small, straightforward scheme, a careful committee can build a workable forecast themselves using the steps above. For larger buildings, structural uncertainty, lifts, or anything with real safety implications, a professional building condition assessment or sinking fund report is worth the cost.
