What Is a Construction Contract Dispute?
Construction projects rarely go exactly to plan. Delays, budget overruns, scope creep, defective work, and unpaid invoices are endemic to the industry. When disputes arise — between owners and builders, builders and subcontractors, or subcontractors and suppliers — they can escalate quickly and become expensive.
A construction contract dispute is any disagreement about the rights and obligations under a building or construction contract. These disputes can arise at any point in a project — during construction, at practical completion, or years later when latent defects emerge.
Queensland law provides several mechanisms for resolving construction contract disputes, ranging from fast-track adjudication under the Building Industry Fairness (Security of Payment) Act 2017 (Qld) (BIF Act) to full Supreme Court litigation. Understanding which option suits your dispute — and acting before time limits expire — is critical.
Common Types of Construction Contract Disputes in Queensland
1. Payment Disputes
Non-payment is the most common source of disputes in the construction industry. A builder may claim for progress payments not certified; a subcontractor may dispute a set-off or backcharge; an owner may withhold payment claiming defects or delay. Under the BIF Act, parties have access to rapid adjudication to recover payment claims — often within 35 business days of applying.
2. Scope and Variations
Construction contracts define the work to be performed. When an owner requests changes, or a builder claims additional work was always within scope, disputes arise over whether a variation was authorised and what it is worth. Variation disputes are among the most heavily litigated categories in the Queensland Supreme Court.
3. Delay Claims
Who bears the cost of delays? Builders may claim extensions of time (EOT) for owner-caused delays, weather events, or latent conditions. Owners may claim liquidated damages (LDs) where the builder failed to reach practical completion on time. Proving and quantifying delay claims requires careful analysis of the project programme, site records, and the contract terms governing EOT entitlement.
4. Defective Work
Defects may emerge during construction (patent defects) or only after practical completion (latent defects). Queensland’s QBCC Home Warranty Insurance scheme provides an additional layer of protection for residential work. For commercial construction, the contract’s defects liability period and rectification obligations are the primary mechanism.
5. Termination Disputes
Purported termination of a construction contract is high-stakes. A party who wrongfully terminates may itself be in repudiation, exposing it to a large damages claim. Construction contracts typically specify the grounds for termination, the notice requirements, and the consequences. Getting this wrong — even procedurally — can be catastrophic.
6. Subcontractor Disputes
In the chain from head contractor to subcontractor to sub-subcontractor, disputes about scope, payment, and liability multiply. The BIF Act applies to all tiers of the construction chain (with limited exceptions), making adjudication an important tool for subcontractors and suppliers who need to be paid quickly.
Key Legislation Governing Construction Disputes in Queensland
| Legislation | Key Provisions |
|---|---|
| Building Industry Fairness (Security of Payment) Act 2017 (Qld) | Payment claims, payment schedules, adjudication process for unpaid progress payments |
| Queensland Building and Construction Commission Act 1991 (Qld) | Licensing, home warranty insurance, QBCC dispute resolution, direction to rectify defects |
| Queensland Civil and Administrative Tribunal Act 2009 (Qld) | QCAT jurisdiction for residential building disputes up to $50,000 (and in some cases higher) |
| Uniform Civil Procedure Rules 1999 (Qld) | Supreme Court and District Court litigation procedure |
| Civil Liability Act 2003 (Qld) | Proportionate liability for economic loss and property damage in construction negligence claims |
Step 1: Review Your Contract Before Doing Anything Else
Before sending a letter of demand or filing an adjudication application, read your contract. Most standard form construction contracts — including ABIC, AS 4000, AS 4902, and HIA contracts — contain:
- Dispute resolution clauses — requiring negotiation, then mediation, before litigation
- Notice requirements — strict time limits for claiming extensions of time or extra costs
- Variation procedures — requirements for written instructions before claiming a variation
- Defects liability provisions — the period during which the contractor must rectify defects and the owner’s right to engage others
- Termination provisions — grounds, notice periods, and consequences
Critical point: Many construction contracts include “no notice, no claim” provisions. If you fail to give the required contractual notice for a delay event or variation within the specified time, you may lose your entitlement entirely — even if you have a valid legal claim. These provisions are strictly enforced by Queensland courts.
Step 2: Pre-Dispute Negotiation
Most construction disputes can and should be resolved without formal proceedings. Before escalating, consider:
- A without-prejudice meeting or telephone call to identify the other party’s position
- A formal letter of demand setting out the claim, the factual basis, and the amount sought
- A request for an engineer’s or superintendent’s determination (if the contract provides for this)
Negotiation is not a sign of weakness. Courts and tribunals expect parties to attempt resolution, and unreasonable failure to negotiate can affect costs orders.
Step 3: BIF Act Adjudication — Fast-Track Payment Recovery
If you are owed money under a construction contract — as a builder, subcontractor, or supplier — the BIF Act provides one of the fastest and most effective dispute resolution mechanisms available in Queensland.
The process in brief:
- Serve a payment claim on the respondent (must be a valid payment claim under the BIF Act — reference date, amount claimed, supporting statement)
- Respondent must serve a payment schedule within 15 business days (or the period in the contract, whichever is shorter) — failure to respond can lead to debt recovery proceedings or deemed acceptance
- Apply for adjudication if the respondent disputes the amount or fails to pay — apply within 10 business days of receiving the payment schedule (or within 20 business days if no payment schedule was served)
- Adjudicator’s decision — typically within 10 business days of receiving the adjudication response
- Enforcement — an adjudicator’s decision can be registered as a court judgment and enforced immediately
Adjudication under the BIF Act is a debt recovery tool. It does not resolve the underlying dispute permanently — a respondent can pursue a debt recovery or damages claim through the courts after paying the adjudicated amount. But it restores cash flow quickly, which is critical in construction.
For a detailed guide to the BIF Act adjudication process, see our article on Security of Payment in Queensland: How to Use the BIF Act.
Step 4: QBCC Dispute Resolution
The Queensland Building and Construction Commission (QBCC) provides a free dispute resolution service for certain residential construction disputes. The QBCC can:
- Inspect disputed work and issue a direction to rectify if defects are found
- Investigate complaints about licensed contractors
- Facilitate mediation between parties
- Determine complaints about defective or incomplete residential work
The QBCC’s jurisdiction is primarily residential. For commercial construction disputes, the QBCC’s role is limited — parties must rely on BIF Act adjudication or court proceedings.
Note: QBCC complaint time limits apply. For defects in completed residential work, a complaint must typically be lodged within 3 years (for structural defects) or 6 years (for other defects covered by Home Warranty Insurance). Read our guide to the QBCC complaint process.
Step 5: QCAT for Smaller Disputes
The Queensland Civil and Administrative Tribunal (QCAT) has jurisdiction to hear certain building disputes, including:
- Disputes about defective or incomplete residential building work
- Disputes between homeowners and QBCC licensed contractors where QBCC has issued a direction to rectify
- General building disputes up to prescribed monetary limits
QCAT is designed to be faster and less expensive than the courts. Parties can appear without legal representation, and the rules of evidence are relaxed. However, QCAT’s jurisdiction has limits — large commercial disputes and disputes about complex legal rights generally require the Supreme Court or District Court.
Step 6: Supreme Court and District Court Litigation
For disputes that cannot be resolved through adjudication, QBCC, or QCAT, full litigation in the District Court or Supreme Court of Queensland may be necessary. Construction litigation is typically conducted under the Uniform Civil Procedure Rules 1999 (Qld) and often involves:
- Expert evidence — quantity surveyors, engineers, building consultants, delay analysts
- Scott Schedule — a structured document listing each disputed item (defect, variation, delay event) with the parties’ respective positions, used by courts to manage complex construction claims
- Technology and Construction List — the Supreme Court’s specialist list for complex construction matters, with a judge experienced in construction law managing the case from filing to trial
- Security for costs — a court may order one party to provide security for the other’s costs, particularly where the claiming party is a corporation at risk of insolvency
Construction litigation in the Supreme Court is expensive and time-consuming. A straightforward dispute may take 12–18 months from filing to trial. A complex dispute can take 3–5 years. This is why BIF Act adjudication and early negotiation are so important — they can resolve disputes in weeks rather than years.
Limitation Periods: Do Not Let Time Run Out
Queensland’s Limitation of Actions Act 1974 imposes strict time limits on when legal proceedings can be commenced:
- Contract claims: 6 years from the date of the breach (or 12 years for claims under a deed)
- Negligence claims: 3 years from when the claimant knew, or ought to have known, of the damage (subject to an overarching 12-year longstop)
- Latent defects: A special rule applies — time may not start running until the defect was discoverable. However, the 12-year longstop is absolute.
BIF Act time limits are far shorter — typically 12 months from the reference date — and missing them can mean losing the right to use adjudication entirely for that claim.
Practical Checklist: If You Have a Construction Dispute
- ✅ Locate and read your contract — all pages, including any annexed schedules
- ✅ Identify the notice requirements for your type of claim and check whether you have complied
- ✅ Preserve your evidence — site diaries, photographs, emails, instructions, payment records
- ✅ Check whether a reference date has arisen for a BIF Act payment claim if money is owed
- ✅ Consider whether negotiation or mediation is required by your contract before formal steps
- ✅ Obtain legal advice — particularly before purporting to terminate or before taking any formal step
- ✅ Act quickly — limitation periods and BIF Act deadlines are unforgiving

Frequently Asked Questions
Can I use BIF Act adjudication for a commercial construction dispute, or is it only for residential work?
The BIF Act applies to both residential and commercial construction contracts. It covers any contract for carrying out construction work or supplying related goods and services in Queensland, subject to limited exceptions (including certain contracts with residential occupants for work on their own home).
What is a “reference date” under the BIF Act?
A reference date is the date on which a payment claim may be made. Under the BIF Act, reference dates arise on the dates specified in the contract for progress claims, or (if the contract does not specify) on the last day of each month during the construction period and on the date practical completion occurs.
My builder has abandoned the site — what can I do?
Abandonment by a builder may constitute repudiation of the contract, entitling the owner to accept the repudiation, terminate the contract, and claim damages (including the cost of completion by a replacement builder). You should first issue a formal notice under the contract requiring rectification or completion within a specified period, unless the abandonment is so clear that notice is unnecessary. Get legal advice before issuing any termination notice.
Can I withhold payment for defective work?
You may be entitled to a set-off against a payment claim if the contract provides for this. However, withholding payment without a proper contractual basis — or without serving a valid payment schedule under the BIF Act — can expose you to an adjudication application and enforcement of the full claimed amount. Always serve a payment schedule within time if you dispute a payment claim.
I am a subcontractor and the head contractor is insolvent — can I still get paid?
Queensland’s Project Trust and Retention Trust Account regime (under the BIF Act) was designed to protect subcontractors when head contractors become insolvent. Whether trust account protections apply depends on the project type and value. There may also be claims under the QBCC Subcontractors’ Charges regime, which allows a subcontractor to claim directly against the project owner in certain circumstances.
