- Construction firms accounted for 24.5% of all insolvencies in Australia, with 3,472 first-time insolvency events recorded, and a second wave is forming in 2026.
- 63% of Master Builders Victoria members are locked into fixed-price contracts that prevent them from passing on rising material and fuel costs, making many contracts financially untenable against typical residential builder margins of 5–10%.
- Significant input cost increases have been documented, including steel duties of up to 82%, PVC price rises of 27%, structural timber up 8.29% year-to-date, and diesel spiking 41% in March 2026 alone.
- Build Metric argues the insolvency crisis is primarily an estimating problem rather than a market problem, with builders submitting fixed-price contracts based on outdated material pricing rather than forward escalation allowances and current supplier costs.
- Managing Director Luke Rose states that builders who are surviving the current climate priced their work correctly at tender, and that estimates lacking escalation clauses or current pricing data are effectively guesses rather than accurate prices.
SOUTH MELBOURNE, Australia — 06 October 2026 — Build Metric, an Australian construction estimating and quantity surveying firm, says the second wave of construction insolvencies forming in 2026 shares the same root cause as the first: builders signing fixed-price contracts on estimates that did not account for the cost environment they were about to deliver into.
Construction firms accounted for 24.5% of all insolvencies, according to ASIC Series 1 data recomputed by Cyberate from the 24 August 2026 release — 3,472 first-time events, against 3,596 the year before. A second wave is forming. 63% of MBV members are locked into fixed-price contracts that prevent them from passing on material and fuel cost increases. Against typical residential builder margins of 5 to 10%, the material movements of 2026 have made the arithmetic on many of those contracts untenable.
The scale of the input cost movement is documented. The Australian Government imposed steel duties up to 82% on Chinese hot-rolled coil and increased rebar duties to 23.7% in May 2026. Plumbing supplier Iplex notified customers of increases of 27% on PVC, 36% on polyethylene and 31% on polypropylene, effective April 2026. Structural timber rose 8.29% year-to-date through Q2. Diesel spiked 41% in March 2026 alone. These are not annual escalation figures. Several moved inside a single quarter.
Build Metric's position is that the insolvency mechanism is not primarily a market problem. It is an estimating problem. A fixed-price contract written on an in-house estimate that treats today's material pricing as the delivery cost is exposed to every movement that follows. An estimate that includes forward escalation allowances, is indexed to current supplier pricing, and is reviewed before contract execution rather than submitted from a spreadsheet carried over from the last similar job is a materially different document.
"The market has been brutal, but the builders who are surviving it priced it properly at tender. We see the difference every day in the briefs that come to us. A builder-prepared estimate on a $2 million job that doesn't include a steel or copper escalation clause, doesn't have current plumbing supplier pricing, and uses last year's diesel rates is not a price. It is a guess. The market didn't change that mid-project. It was wrong at submission," said Luke Rose, Managing Director of Build Metric.
