DoT actively encourages participation of Aboriginal businesses in the delivery of its state-wide works program and is striving to exceed targets set within the State Government’s Aboriginal Procurement Policy.

Project bank accounts (PBAs)

A project bank account (PBA) is a bank account that operates under a trust for Department of Transport construction contracts that meet certain value thresholds. Rather than monthly payments being made from Department of Transport directly to the contractor’s regular bank account, monthly payments are paid into the PBA and funds are the dispersed to the contractor’s regular bank account and participating subcontractors and suppliers in the supply chain at the same time.

  • PBAs are intended to:
  • provide a degree of insolvency protection;
  • speed up the payment process for parties lower down in the supply chain; and
  • increase transparency and accountability in the payment process.

PBAs apply to construction contracts where the tender sum is at or above $1.5 million (including GST), and the contractor will engage one or more subcontractors. The model only applies to first tier subcontractors, not second tier subcontractors.

How does this affect contracts?

  • Department of Transport works contracts at or above $1.5 million now include the use of PBAs.
  • Head contractors are required to:
  • Establish a PBA at the start of the contract.
  • Advise details of eligible subcontractors (contract value >$20,000 (inc. GST))
  • Payment claims will include the progress claim from the Contractor, plus a breakdown of payments for subcontractors.

PBA documents

Where a PBA applies, relevant documents will have been provided to you upon contract award. A copy of the Contractor’s Guide to setting up a PBA for Department of Transport contracts is provided below.

Further information

Further general information can be found below, however Department specific amendments may apply so always refer to documentation provided upon contract award.
