Civil and earthworks subcontracts in Australian Capital Territory: what to check before you sign
In Australian Capital Territory, a civil subcontract is read alongside the Building and Construction Industry (Security of Payment) Act 2009 (ACT), which gives you the right to make a payment claim and requires a payment schedule within 10 business days if the builder disputes it. The contract itself still decides the risks that cost civil and earthworks subcontractors most: latent conditions; quantities and remeasurement; standing time for plant and crews.

Australian Capital Territory rules that override your contract
Statute: Building and Construction Industry (Security of Payment) Act 2009 (ACT)
- If the builder disputes a payment claim, it has to answer with a payment schedule within 10 business days (or any shorter period in the contract).
- Jurisdiction follows the contract rather than where the work is performed, so Canberra-region jobs that cross the NSW border need care about which Act applies before any notice is served.
- Adjudication: through a private authorised nominating authority, with determinations typically within 10 business days of acceptance.
Where civil and earthworks subcontractors lose money
Latent conditions
Rock, contamination and services that weren't in the investigation reports can transform the cost of the job. A clause that puts all ground risk on you, regardless of the information provided, is one of the most expensive in civil work.
Quantities and remeasurement
Lump sums on uncertain quantities shift the risk to you. Schedule of rates or remeasure for bulk items protects against swings.
Standing time for plant and crews
When the builder or another party stops the work, your plant still costs money. Make sure stand-downs caused by others are paid.
Weather and wet ground
Wet ground can stop earthworks for days after rain stops. Extension of time and cost for weather should reflect that.
Three things to push for in your departures schedule
- Latent conditions shared, with relief where conditions differ from the reports
- Schedule of rates or remeasure for uncertain quantities
- Standing time paid when others stop the works
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 3 civil and earthworks contracts so far, under the 10-contract threshold, so these are national figures across all trades. Nothing under 10 contracts is ever shown.

Is this legal advice?
No. It is general information about common subcontract risks and the state's payment law as recorded in our registry. Statutory details change; check the current Act, and take the scanner's report to a construction lawyer for decisions with legal consequences.
