Concrete and formwork subcontracts in Queensland: what to check before you sign
In Queensland, a concrete subcontract is read alongside the Building Industry Fairness (Security of Payment) Act 2017 (QLD), which caps subcontract payment terms at 25 business days. The contract itself still decides the risks that cost concrete and formwork subcontractors most: liquidated damages without a cap; weather and inclement days; quantity and design changes.

Queensland rules that override your contract
Statute: Building Industry Fairness (Security of Payment) Act 2017 (QLD)
- Payment terms for subcontractors are capped at 25 business days after the payment claim. A longer term in the contract doesn't change that.
- If the builder disputes a payment claim, it has to answer with a payment schedule within 15 business days (or any shorter period in the contract).
- Adjudication applications go to the QBCC Adjudication Registry rather than a private nominating authority, and if the builder misses the payment schedule deadline it becomes liable for the full claimed amount and is barred from raising reasons at adjudication.
- Adjudication: generally 30 business days from the relevant trigger for a standard application, lodged with the QBCC.
- Statutory trusts apply on some projects.
Where concrete and formwork subcontractors lose money
Liquidated damages without a cap
Because structure sits on the critical path, a late pour can delay the whole project. An uncapped liquidated damages clause exposes you to the builder's entire delay cost. Push for a cap, commonly 5 to 10 percent of the subcontract sum.
Weather and inclement days
Check whether wet days give an extension of time automatically or only above an allowance, and whether you need to notify each day. A daily notice requirement with an absolute bar is easy to miss in a wet month.
Quantity and design changes
Thickened slabs, extra reinforcement and late design changes change your quantities. A lump sum with no remeasure or rates for changes leaves the extra concrete and steel unpaid.
Pump, crane and access dependencies
If access, crane time or pump positions depend on the builder, the contract should treat interruptions as delay events, not your risk.
Three things to push for in your departures schedule
- Liquidated damages capped at 5 to 10 percent of the subcontract sum
- Extension of time for inclement weather with a simple monthly notice
- Agreed rates for quantity changes and design revisions
The free scanner finds these clauses in your actual contract in about two minutes and writes the departures schedule for you.
What the Index says
Live figures from the Australian Subcontract Index, 90 real subcontracts. The Index holds only 8 concrete and formwork contracts so far, under the 10-contract threshold, so these are national figures across all trades. Nothing under 10 contracts is ever shown.

Concrete and formwork subcontracts in QLD: common questions
How long does a builder in QLD have to pay a concrete and formwork subcontractor?
No more than 25 business days after your payment claim, whatever the contract says. If the builder disputes the claim, it has 15 business days to answer with a payment schedule giving its reasons.
Are uncapped liquidated damages normal in concrete subcontracts?
They are common, which is why they are worth negotiating. An uncapped clause can expose you to the builder's entire delay cost for a package that may be a small share of the project. A cap of 5 to 10 percent of your subcontract sum is a widely used market position.
Where do QLD concrete and formwork payment disputes go?
