A step-by-step operational guide for head contractors and civil subcontractors to ensure payment claims, payment schedules, and variation notifications stay legally compliant.
The Statutory Backbone of Construction Cash Flow
The Building and Construction Industry Security of Payment Act provides subcontractors and head contractors with an enforceable legal framework to recover payments without engaging in lengthy courtroom litigation. However, the legislation operates on rigid, non-negotiable statutory timelines that punish administrative delay.
Step 1: Establishing Valid Reference Dates
A payment claim must be served on or from each contractual reference date. In the absence of an express clause, statutory default reference dates apply. Serving a claim prematurely or failing to identify the relevant reference date can render the entire claim legally invalid under adjudication.
Step 2: Mandatory Endorsement Language
In NSW and the ACT, payment claims must state that they are made under the relevant Security of Payment Act. Furthermore, head contractors issuing claims to principals must accompany the claim with a compliant Supporting Statement confirming that all secondary subcontractors and workers have been paid up to date.
Step 3: The Critical 10 Business Day Payment Schedule Window
When receiving a payment claim from a subcontractor, the respondent has 10 business days (or shorter if stipulated in the contract) to provide a formal Payment Schedule. If you fail to serve a Payment Schedule within this timeframe, you become legally liable to pay the entire claimed amount on the due date for payment, forfeiting the right to dispute the quality or quantity of work.
Step 4: Substantiating Variations with Evidence
Never rely on verbal handshakes on site. Every variation must be backed by a written Site Instruction (SI) or Request for Information (RFI), accompanied by marked-up drawings, plant hire dockets, and labour timesheets. SUCHAN manages this evidentiary pipeline to ensure every claim withstands rigorous legal scrutiny.
