The Western Australia framework
The relevant legislation is the Building and Construction Industry (Security of Payment) Act 2021 (WA).
The contract date matters. The 2021 Act applies to contracts entered into on or after 1 August 2022. Earlier contracts require consideration under the former provisions. We identify the applicable scheme before reviewing the claim, response and adjudication pathway.
Our preparation work
We review the parties and contract, identify the claimed entitlement, reconcile the amount and organise the evidence. The written case addresses the disputed issues and links them to the supporting documents.
Dates and documents
Provide the contract date, project location, each payment claim and schedule, the payment due date and evidence of when documents were sent and received. Include any earlier adjudication involving the same work.
