Payment

How are payments to contractors, design consultants and subcontractors normally structured?

Methods of payment vary according to the works. The four main types of contract sum are calculated as follows:

  1. Lump sum: The contract sets out a pre-agreed sum that the contractor/consultant/sub-contractor will be paid to carry out either a stage or the whole of the works that are required under the contract (subject to various provisions, including variations for which the contractor may receive additional monies)
  2. Measurement: The work is measured and valued according to a formula or schedule of rates
  3. Cost plus: Payment is by prime cost plus an added percentage for profit
  4. A combination of the above for example the base works may be a lump sum but variations may be carried out on a measured basis

For each of these methods, payment is usually made against the certification of completed works by the contract administrator. The inspection and certification of completed works can be made on a periodic basis (usually monthly) or a milestone basis (at pre-agreed specific milestones or stages).

Each Australian state and territory now has legislation dealing with security of payment for contractors, suppliers and subcontractors in the infrastructure industry and for those who provide related goods and services (such as engineers and architects).

While the detail varies from state to state, the SOP legislation has the following features:

  • It enshrines a statutory right to payment for infrastructure work and services. In some jurisdictions this right is granted even if there is a similar existing right in the relevant infrastructure contract. In other jurisdictions it is only granted if the relevant contract contains no payment regime.
  • It specifies a process which must be followed by both the party claiming under that statutory right, and the party who is liable to make payment.
  • It prohibits ‘pay when paid’ clauses and other clauses considered adverse to a contractor’s right to be paid for work carried out.
  • It prescribes a type of fast track dispute resolution in the form of adjudication of payment claims under contracts.

Some SOP Acts (such as those enacted in the Northern Territory and Western Australia) give a party a right to claim payment in respect of the work or services only if the relevant contract does not contain any provision for payment.

In other SOP Acts, notably those in Victoria, New South Wales and Queensland, the statutory right exists regardless of the presence in the applicable contract of provisions giving a right to a party to claim payment for work and services. This statutory right sits in parallel with the contractual right to payment.

The SOP legislation enacted in Australia has the following important impacts:

  • It ‘speeds’ up certification of payment claims and requires contractors to have efficient contract administration processes.
  • It improves the cash flow to subcontractor and suppliers, and means that contractors cannot rely on delaying payment to sustain cash flow and liquidity.
  • It may have reduced the number of major disputes as many of these may be resolved at the adjudication stage.

Depending on the jurisdiction in which the works are being carried out, most construction and infrastructure contracts need to contain provisions dealing with SOP.

Such provisions will not be standard, as careful consideration needs to be given to the nature of the project and how the payment provisions are intended to work. For example:

  • In some jurisdictions, imposing a pre-condition on payment of a contractor or subcontractor, such as the provision of insurance details or security, may be in breach of the relevant SOP Act.
  • Not all construction work is covered by the relevant SOP Act. Notable exclusions to the operation of the SOP Act in most jurisdictions are mining work, residential building work and work where the payment under the contract is not the value of the work performed but some other mechanism (as may be the case in a build own transfer project).
  • There still exists in some jurisdictions legislation which gives contractors a right to place a charge over monies payable to the contractor (in the case of Queensland) or a lien over property to secure payment (in the case of South Australia).
