Security of Payment: How Subcontractors Recover Money Under SOPA

Security of payment in Queensland is governed by the Building Industry Fairness (Security of Payment) Act 2017 (Qld). The BIF Act provides contractors, subcontractors, and suppliers with a statutory right to recover progress payments for construction work and related goods and services. If a payment dispute arises, the Act provides for rapid adjudication — a binding interim process that resolves disputes within weeks. Boss Lawyers in Brisbane regularly acts for subcontractors, contractors, and principals in security of payment disputes across Queensland.

The Scenario

A common situation arises when a subcontractor completes $180,000 worth of electrical work on a commercial construction project in Brisbane. The subcontractor submits a payment claim to the head contractor, who either ignores it, disputes the amount without clear justification, or simply refuses to pay. The subcontractor has workers to pay, materials suppliers chasing invoices, and cash flow is tightening rapidly.

In situations like this, Queensland’s security of payment legislation provides a fast-track mechanism to recover money owed — without the cost and delay of traditional court proceedings.

The Legal Framework

The Building Industry Fairness (Security of Payment) Act 2017 (Qld)

The Building Industry Fairness (Security of Payment) Act 2017 (commonly known as SOPA or BIF Act) establishes a statutory right to progress payments for construction work and related goods and services in Queensland. Its purpose is to ensure money flows down the contracting chain and that subcontractors are paid promptly for work they have performed.

Key Features

• Statutory right to progress payments — any person who carries out construction work or supplies related goods and services under a construction contract is entitled to a progress payment (s 64)
• Payment claims — a claimant can serve a payment claim on the respondent identifying the work done and the amount claimed (s 68)
• Payment schedules — the respondent must provide a payment schedule within the required timeframe (usually 15 business days for subcontracts), indicating the amount they propose to pay and reasons for any difference (s 76)
• Adjudication — if the respondent fails to provide a payment schedule, or provides one for a lesser amount, the claimant can refer the dispute to rapid adjudication (s 79)

The Adjudication Process

Adjudication under the BIF Act is designed to be fast, cost-effective, and interim. Key features include:

• An authorised nominating authority (ANA) appoints an adjudicator
• The adjudicator must decide the dispute within 10 business days of accepting the application (extendable to 15 by agreement)
• The adjudication decision is binding on an interim basis — “pay now, argue later”
• If the respondent does not pay the adjudicated amount, the claimant can file the decision as a judgment debt in court and enforce it
• The respondent can also face suspension of work by the claimant if the adjudicated amount is not paid

How It Typically Unfolds

1. Serve a valid payment claim — the claim must comply with the Act’s requirements, including identifying the construction work, the amount claimed, and being served within the required timeframe. Strict compliance is essential
2. Wait for a payment schedule — the respondent has a limited window (typically 15 business days for subcontracts) to respond with a payment schedule
3. If no schedule or underpayment — the claimant can apply for adjudication. The application must be lodged within strict timeframes (generally 20 business days after the payment schedule was due or received)
4. Adjudication — the adjudicator reviews the payment claim, payment schedule (if any), and submissions, then issues a decision
5. Enforcement — if the adjudicated amount is not paid, the claimant can obtain a court judgment and enforce it through standard enforcement mechanisms (garnishee orders, examination hearings, etc.)

Key Takeaways

• Timeframes are strict and unforgiving. Missing a deadline — whether for serving a payment claim, providing a payment schedule, or lodging an adjudication application — can be fatal to your position
• “Pay now, argue later.” The adjudication process is deliberately tilted in favour of cash flow. A respondent who disagrees with an adjudication decision can still pursue the dispute through litigation or arbitration, but must pay the adjudicated amount first
• Respondents must engage. Failing to provide a payment schedule is one of the most common — and most costly — mistakes. Without a payment schedule, the respondent loses the right to raise reasons for withholding payment in adjudication
• The Act applies broadly. It covers most construction work in Queensland, including building, civil, mechanical, electrical, and fitout work. It applies to both commercial and residential projects
• Get the paperwork right. A payment claim that does not comply with the Act’s requirements may be invalid. Attention to detail in preparing and serving claims is critical

When to Seek Legal Advice

Whether you are a subcontractor preparing a payment claim or a head contractor who has received one, the strict timeframes and technical requirements of the BIF Act make early legal advice essential. A misstep in the process can mean the difference between recovering what you are owed and losing your right to claim.
