You discover your builder has been placed into liquidation. The site is locked. The project is half-finished. Your tenant is supposed to move in in three months.
Where do you even start?
Builder insolvency mid-project is no longer rare. Rising costs, supply chain pressure, and tight margins have made contractor failure a normal part of the construction landscape. If it happens to you, the question is not “Can I avoid all loss?” but “How do I keep control of the site, the money, and the timeline?”
This is about practical decisions, not legal theory. You have three problems at once: an unfinished asset, a disrupted contract, and an insolvency process. The decisions you make in the first 72 hours will set the tone for everything that follows.
Can you finish the project with a replacement builder? Probably, but not without pain. Can you recover any money? Maybe, if you understand what you’re entitled to and where it sits. Can you avoid making the situation worse? Absolutely, if you stay clear-headed and avoid common traps.
This article walks you through what happens when a builder becomes insolvent during construction, what your rights are under your contract and the law, and what you should do next to protect your interests.
Key Takeaways
- Insolvency triggers contractual rights, most construction contracts allow termination if the builder goes into liquidation or administration, but you must follow the notice process exactly to avoid wrongful termination claims
- Secure the site immediately, your first priority is preventing unauthorised work, damage, or removal of materials while you assess your position and understand what’s on site
- Money recovery is difficult but possible, deposits and progress payments are usually lost unless you have insurance, retention money may be protected in trust accounts, and you’ll need to lodge a proof of debt in the liquidation
- Ownership of materials is not automatic, just because materials are on your site does not mean you own them; PPSR registrations and contractual terms determine who has priority
- Replacement builders cost more and take longer, completing a partially finished project with a new builder almost always costs more than the original contract price, and someone needs to take responsibility for defects in the original work
- Insurance may help, but only if you qualify, home warranty schemes exist for residential work in some states, but commercial projects rarely have equivalent protection unless you arranged specific insurance upfront
When a Builder Becomes Insolvent: What It Means for Your Project
Builder insolvency means the company cannot pay its debts as they fall due. In practice, it usually means an external administrator or liquidator has been appointed, and control of the company’s affairs has passed to them.
You will see one of three scenarios.
Voluntary administration. The builder appoints an administrator to try to save the business or arrange a better return for creditors than immediate liquidation. Work may continue in some cases, but the administrator has no obligation to finish your project.
Liquidation. The company is being wound up. Work stops. The liquidator’s job is to realise assets and distribute funds to creditors in order of priority. Your project is not the liquidator’s concern. Recovery of what you can is.
Receivership. A secured creditor (usually a bank) appoints a receiver to take control of specific assets. Work stops. The receiver’s loyalty is to the lender, not to you.
In all three situations, the practical effect is the same: work halts, the builder’s team leaves site, and the legal status of the contract changes. You cannot simply ignore the insolvency and keep paying invoices as if nothing has happened.
The insolvency triggers rights under your contract. It also starts a formal creditor process under the Corporations Act. You are now one creditor among many, and what happens next depends on how quickly and carefully you act.
The moment you learn of the insolvency, the contract and the project enter a different legal state. Decisions you make assuming “business as usual” will backfire.
Your First 72 Hours: Securing the Site and Understanding Your Position
The first three days after learning of the builder’s insolvency are critical. Panic will cost you. So will delay.
Here is what you need to do, in order.
Stop all unauthorised work. If subcontractors are still on site, tell them to stop immediately. You do not have authority to direct them to continue, and the builder no longer has authority to engage them. Work done after the insolvency may not be your responsibility to pay, but disputes about who authorised what will eat time and legal costs.
Secure the site. Change locks if you control access. Prevent anyone removing materials, equipment, or partially completed work. Ownership of those items is unclear until you review the contract and any PPSR registrations. Removing materials that belong to the builder’s estate or a supplier can expose you to claims from the liquidator.
Document everything. Walk the site with a camera or video. Record what work has been completed, what materials are on site, what equipment is there, and the condition of everything. Take photos of any defects or incomplete elements. This record will be essential when you negotiate with a replacement builder, lodge insurance claims, or prove debts in the liquidation.
Review your contract. Find the insolvency clause. Most construction contracts give the principal the right to terminate if the builder enters administration or liquidation. Read the termination provisions carefully. They will specify notice periods, who you must notify, and what you must do to validly terminate. Getting this wrong can expose you to a wrongful termination claim, even if the builder is insolvent.
Notify stakeholders. Tell your financier, insurer, quantity surveyor, and project manager immediately. If you have tenants waiting to move in, warn them of delays. If you have guarantees or bonds from the builder, notify the guarantor or insurer. Time limits often apply.
Avoid knee-jerk decisions. Do not immediately engage another builder to start work. Do not pay subcontractors directly unless you have clear legal advice that you are liable to do so. Do not remove materials from site assuming they are yours. Each of these actions can create new problems. Take 72 hours to understand your position before committing to a path.
In practice, most principals will do four things in the first week: secure the site, document what is there, read the contract, and get advice on termination and next steps.
If you engage a quantity surveyor to inspect and value the work completed, that report becomes your foundation for everything that follows: negotiating with the replacement builder, lodging a proof of debt, and claiming under insurance if available.
Reading Your Contract: Termination, Rights, and Risks
Your contract is your starting point. Not the legislation. Not what you think is fair. The contract.
Most construction contracts contain an insolvency clause. It usually says something like: “If the builder becomes insolvent, enters administration, or has a liquidator appointed, the principal may terminate this contract by written notice.”
That sounds simple. It is not.
Notice requirements matter. The contract will specify how you must give notice (email, registered post, hand delivery), who you must notify (the builder, the administrator, the builder’s solicitor), and how long the other party has to remedy or respond. If you give notice in the wrong way, or to the wrong person, the termination may not be valid.
Consequences of termination. Once you validly terminate, the builder’s obligation to complete the work ends. Your obligation to pay for completed work may continue, depending on the contract terms. You will need to engage a replacement builder to finish the project. The contract may give you the right to claim delay costs, defects costs, and the difference between the original contract price and the cost of completion. Those rights exist on paper. Recovering them from an insolvent company is another matter.
Risk of wrongful termination. If you purport to terminate but the termination is invalid (wrong notice period, wrong trigger, wrong process), you are in breach of contract. The liquidator can then claim damages against you for wrongful termination. That claim may include the builder’s loss of profit on the remaining work. It sounds absurd when the builder is insolvent, but it is legally possible, and it happens.
Interaction with the liquidator. Once the builder is in liquidation, the liquidator controls the company’s affairs. Any notice you give must go to the liquidator. The liquidator may disclaim the contract (walk away from it) or affirm it (try to keep it alive). In practice, most liquidators disclaim construction contracts because the builder cannot perform. Your termination and the liquidator’s disclaimer often happen at the same time. That is fine. What matters is that you follow the contractual process.
Step-in and assignment rights. Some contracts give the principal the right to “step in” and take over the builder’s role, engaging subcontractors directly and using the builder’s plant and materials to complete the work. Other contracts allow the principal to assign the contract to a replacement builder. These clauses are valuable if they exist, but they are not standard. If your contract does not have them, your only option is termination and re-tendering the remaining work.
Can you articulate, in one sentence, what your contract says about insolvency and termination? If you cannot, you do not yet understand your position.
A liquidator’s job is to maximise recovery for creditors. If your termination notice is defective, the liquidator will use that defect to argue you owe more money. Precision matters.
Money, Insurance, and Recovery Options
Let’s talk about what you have already paid, and what you might recover.
Deposits. If you paid a deposit upfront, it is usually gone. Deposits sit in the builder’s general account and form part of the insolvent estate. You rank as an unsecured creditor. In most liquidations, unsecured creditors recover cents in the dollar, often zero. Unless the builder was required to hold the deposit in trust (rare in commercial contracts), you will not get it back.
Progress payments. Money paid for work completed is not recoverable. You paid for value received. The fact that the builder later became insolvent does not change that. Money paid in advance for work not yet done may be recoverable, but again, you rank as an unsecured creditor and recovery is unlikely.
Retention money. This is different. In some states, retention money must be held in a separate trust account or project trust account. If it is held in trust, it is protected from the builder’s general creditors and should be available to you. In Queensland, for example, project trust accounts ring-fence retention and progress payments for the benefit of subcontractors and principals. Check whether your contract required retention to be held in trust, and whether the builder complied. If the money is there, you can access it. If it was not held in trust, it is part of the insolvent estate.
Home building compensation and warranty insurance. If this is a residential project in New South Wales, Victoria, Queensland, South Australia, or Western Australia, the builder may have been required to take out home warranty insurance. This insurance covers you (the homeowner) if the builder becomes insolvent and the work is incomplete or defective. Coverage is capped (usually $300,000 to $600,000 depending on the state) and you will need to lodge a claim with the insurer, supported by quotes to complete the work and a defects report. The insurer will then assess the claim and pay for rectification or completion, subject to the policy terms. This is a genuine safety net for residential owners, but it does not exist for commercial projects unless you arranged specific insurance upfront.
Proof of debt in the liquidation. You should lodge a proof of debt with the liquidator for any money you are owed: deposits, overpayments, costs of rectifying defects, costs of delays caused by the builder’s breach. Lodging a proof of debt does not guarantee recovery, but it is a prerequisite. The liquidator will assess the claim and include it in the distribution to creditors. If there are funds left after secured creditors are paid, you may receive a dividend. In practice, unsecured creditors in construction liquidations often receive nothing.
Security of payment claims. If the builder owes you money for completed work (unusual, but possible in some contract structures), you may have rights under your state’s security of payment legislation. These rights allow you to make a payment claim, refer the matter to adjudication, and potentially suspend work or terminate if payment is not made. Security of payment rights can survive insolvency in some circumstances, but they are complex and time-sensitive. Most principals do not have security of payment claims because they are paying the builder, not the other way around. However, if the builder has overclaimed or you are entitled to damages for delay, you may be able to set off those amounts against future payments.
Insurance you arranged. If you took out contract works insurance, delay insurance, or professional indemnity insurance for your consultants, check the policy terms. Some policies cover you for the cost of rectifying defective work or completing the project if the builder fails. These are not standard, but if you have them, notify your insurer immediately.
The blunt truth is that money recovery from an insolvent builder is difficult. The best outcome is usually minimising additional loss by finishing the project efficiently, not chasing the liquidator for funds that do not exist.
Lodge your proof of debt within the timeframe the liquidator sets (usually 28 days from the notice). Even if you recover nothing, having your claim on the record can support future litigation if you later discover the builder was trading while insolvent or engaged in misconduct.
Who Owns the Work and Materials Now?
This question causes more confusion than almost any other.
You assume that because materials are on your site, or because work has been done on your land, you own them. That assumption is often wrong.
Completed work. Once the builder has incorporated materials into the building (bricks laid, beams fixed, plasterboard installed), those materials usually become part of the land. You own them because you own the land. The builder cannot remove them. This is a basic property law principle. But there is a catch: if the builder has not been paid for that work, and a supplier has a valid security interest registered on the Personal Property Securities Register (PPSR), the supplier may have priority over you. The supplier can argue they retain ownership of the materials until paid, even though the materials are now part of your building. This creates a dispute. In practice, suppliers rarely try to rip materials out of a completed building, but they can and do threaten to do so to extract payment.
Materials delivered but not yet installed. Bricks stacked on site. Timber in the shed. Fixtures in boxes. These materials may not be yours. If the builder has not paid the supplier, and the supplier has registered a PPSR interest, the supplier owns the materials and can remove them. If the builder’s liquidator claims the materials as part of the builder’s estate, the liquidator can remove them. If you have paid the builder for those materials under a progress claim, you may have an argument that you own them, but that argument is not automatic. Ownership depends on the contract terms, whether title passed when you paid, and whether anyone else has a prior registered interest.
Plant and equipment. The excavator on site. The scaffolding. The builder’s tools. You do not own these. The builder owns them, or more likely, they are leased or subject to a finance agreement. The liquidator or the financier will remove them. Do not try to prevent that. You have no right to the builder’s plant.
What about retention of title clauses? Many suppliers include retention of title clauses in their terms and conditions, which say “title to goods does not pass to the buyer until payment in full”. If the supplier has validly included that clause and registered it on the PPSR, they can reclaim unpaid goods. If you have paid the builder but the builder has not paid the supplier, you may be caught in the middle. The supplier says “we own the materials, we are taking them back”. You say “I paid for those materials”. The reality is that both of you have been let down by the builder, and you will need to negotiate. Often, you end up paying the supplier again, then lodging a proof of debt with the liquidator for the amount you already paid the builder.
What should you do? Do not remove materials from site. Do not allow subcontractors or suppliers to remove materials until you have checked the PPSR and confirmed their interest. Conduct a PPSR search against the builder’s ABN to see what security interests are registered. If materials are subject to a registered interest, you will need to negotiate with the secured party. If they are not, and you have paid for them, you can argue they are yours.
Can you confidently say who owns the steel sitting in your site compound right now? If you cannot, you need to find out before someone drives in and removes it.
Paying the builder for materials does not automatically make you the owner. If the builder has not paid the supplier, and the supplier has registered security, you may need to pay twice or watch the materials leave your site.
Bringing in a Replacement Builder Without Making Things Worse
You have secured the site. You have terminated the contract. Now you need to finish the building.
Getting a replacement builder in is not as simple as calling three contractors and picking the cheapest quote.
Scope the remaining work carefully. You need a detailed scope that says exactly what is left to do, what is already done, and what is defective and needs rework. This is why the quantity surveyor’s report is essential. The replacement builder needs to know whether they are finishing 40% of a project or 60%, whether the existing work is to standard, and what risks they are inheriting.
Expect a pricing premium. Replacement builders charge more than original builders. They are stepping into someone else’s mess. They are taking on defect risk. They have no relationship with the subcontractors. They are working to a tight timeframe because you have already lost months. They price all of that risk into their quote. If your original contract price was $2 million and 50% of the work is done, you will not get the remaining 50% done for $1 million. You will pay $1.2 million, $1.3 million, maybe more.
Get a defects report. Before the replacement builder starts, get an independent expert to assess the quality of the work already done. If there are defects, document them. Agree with the replacement builder who is responsible for fixing them. If you do not do this upfront, the replacement builder will later say “that defect was there when we started, it is not our responsibility”, and you will be stuck with a dispute about who is liable.
Clarify warranty responsibility. Under most construction contracts, the builder warrants that their work is free from defects for a certain period (often 12 months for minor defects, 6 years for major structural defects under statutory schemes). If a new builder completes the project, who is responsible if a defect appears in the original builder’s work? Not the replacement builder, unless they agreed to take that on. Not the original builder, because they are insolvent and gone. The answer is usually: you. You carry the risk of defects in the original work unless you have insurance or can recover from the liquidator (unlikely). This is one of the hidden costs of builder insolvency. You may need to spend money rectifying defects that are not your fault and that you cannot recover from anyone.
Manage subcontractor continuity. Some subcontractors may be willing to continue working under a new head contract. Others will not. If a subcontractor is owed money by the insolvent builder, they will not come back unless you pay them what they are owed. That creates a tension: the liquidator may argue you have no obligation to pay the subcontractor because they contracted with the builder, not you. The subcontractor says they will not work unless paid. You say you already paid the builder. Someone has to give. In practice, you often end up paying the subcontractor again to keep the project moving, then lodging a proof of debt with the liquidator for what you have paid twice. It is frustrating, but the alternative is delay.
Re-tender intelligently. Do not just send the scope to three builders and take the lowest price. Interview them. Ask about their experience finishing other contractors’ work. Ask how they will manage defect risk. Ask for a detailed programme showing how long completion will take. Ask about provisional sums and variations. A cheap quote from a builder who does not understand what they are pricing will cost you more in the long run than a realistic quote from a builder who has walked the site and knows what they are dealing with.
Most principals underestimate the time and cost of bringing in a replacement builder. If you assume it will take three months and cost an extra 20%, you will be disappointed. Plan for six months and 30% extra, and be pleasantly surprised if you do better.
Negotiate a fixed-price contract with the replacement builder if possible, even if it costs slightly more. You have already absorbed one builder’s failure. The last thing you need is a second cost-plus contract that spirals out of control.
Common Traps When Dealing with Contractor Insolvency
Here is what goes wrong.
Trap 1: Terminating without following the contract process. You are angry. The builder has let you down. You send an email saying “you are fired, we are bringing in someone else”. That email is not a valid termination notice under the contract. The liquidator argues you wrongfully terminated and the builder’s loss of profit on the remaining work is your fault. You now owe damages. Follow the contract. Use the exact termination process it specifies.
Trap 2: Removing materials that are not yours. You see materials on site. You assume they are yours because you paid the builder. You use them to keep the project moving. Later, a supplier turns up with a PPSR registration and says “those materials are ours, you have used our property, you owe us the replacement cost”. You have exposed yourself to a conversion claim. Do not touch materials until you know who owns them.
Trap 3: Paying subcontractors directly without checking your obligations. A subcontractor comes to you and says “the builder owes us $50,000, if you do not pay us we will lodge a lien and stop the project”. You pay them. Later, the liquidator argues you had no obligation to pay them, and the $50,000 you paid was money that should have gone to the builder’s creditors. You have now paid twice: once to the builder under a progress claim, once to the subcontractor. You may not recover either payment. Before paying any subcontractor directly, get clear advice on whether you are legally required to do so.
Trap 4: Assuming insurance will cover everything. Home warranty insurance in residential projects has caps. It does not cover delay costs. It does not cover your time. It does not cover the premium you pay to the replacement builder. If you assume insurance will make you whole, you will be disappointed. Read the policy. Understand the exclusions. Budget for the shortfall.
Trap 5: Delaying action because you hope the builder will recover. If the builder is in voluntary administration, there is a slim chance they will trade out of it and complete your project. That chance is about 5%. Do not sit and wait. The longer you wait, the more the site deteriorates, the more subcontractors leave, the harder it is to pick up the pieces. Secure the site, document everything, and start planning for completion with a new builder. If the builder does recover, you can reverse course. But if they do not, you have not lost two months waiting.
Trap 6: Not lodging a proof of debt. You assume there is no money in the liquidation, so why bother? Lodge the proof of debt anyway. It costs nothing. It preserves your rights. If assets are later discovered, or if the liquidator pursues claims against directors for insolvent trading, you want your claim on record. If you do not lodge, you may be excluded from any distribution.
Each of these traps is avoidable. The common thread is acting on assumption instead of checking the contract, the law, and the facts.
When a builder becomes insolvent, instinct tells you to move fast and fix the problem. Instinct is often wrong. Moving carefully and getting advice first prevents most of the traps.
Managing the Timeline and Budget Blowout
Let’s be honest. This is going to cost you more money and more time than you planned.
How much more depends on how far through the project you were when the builder failed, how good your contract was, and how quickly you act.
Typical delay: 3 to 6 months. From the moment the builder stops work to the moment a replacement builder is on site and working will usually take three to six months. That includes securing the site, documenting the position, terminating the contract, re-tendering the remaining work, negotiating a new contract, and mobilising the replacement builder. If your project was supposed to finish in two months, it will now finish in five to eight months. Plan for that. Notify your tenants, your financier, your stakeholders.
Typical cost escalation: 20% to 40% of the remaining contract value. If half the work is done and the remaining contract value was $1 million, budget for the replacement builder to charge $1.2 million to $1.4 million. That includes the pricing premium, the cost of rectifying defects, the cost of remobilisation, and the cost of acceleration if you try to claw back lost time. If you can finish for less, excellent. But do not assume you will.
Other costs you will incur. Legal advice on termination. Quantity surveyor to assess completed work and value remaining work. Defects consultant to report on the existing work. Project manager to oversee the replacement builder (if you did not already have one). Insurance excess if you make a claim. Interest on your financing for the extended period. Opportunity cost if you are unable to lease or operate the building while it sits unfinished.
Add it up, and builder insolvency mid-project can easily cost you 30% to 50% more than the original budget, and six to twelve months more than the original timeline.
Can you carry that cost? Can your business absorb that delay? If the answer is no, you need to talk to your financier and your advisers now, not when you run out of cash three months into the replacement build.
The projects that recover best are the ones where the principal acknowledges the reality early, re-budgets, re-plans, and communicates transparently with stakeholders. The projects that go badly are the ones where the principal keeps pretending it will all work out and runs out of time or money halfway through the replacement build.
Build a contingency into your revised budget of at least 10% on top of the replacement builder’s quote. You will need it when variations arise, when defects are discovered, or when delays occur. Better to finish under budget than run out of money when you are 80% done.
Planning Ahead: Reducing the Impact of Builder Insolvency on Future Projects
You cannot eliminate the risk of builder insolvency. But you can reduce its impact.
Here is what smart principals do before they sign the next construction contract.
Pre-contract due diligence. Check the builder’s financial position before you engage them. Ask for recent financials. Check their credit rating. Search ASIC for any charges or securities registered against them. Talk to other clients. Ask how many projects they are running concurrently. A builder juggling ten projects is more likely to fail than a builder focused on three. If a builder refuses to provide financials or is evasive about their position, walk away.
Security and guarantees. Require the builder to provide a bank guarantee or insurance bond for a meaningful percentage of the contract value (10% to 20%). That guarantee is your safety net if the builder fails. You call on the guarantee to cover the cost of completing the work. Builders will resist this because it ties up their capital. Insist on it anyway. If they cannot provide a guarantee, they are not financially stable enough for your project.
Parent company guarantees and director guarantees. If the builder is a subsidiary or a special purpose company, require a guarantee from the parent company or the directors personally. This gives you a solvent party to pursue if the builder fails. Many builders set up project-specific companies with minimal assets to limit their liability. A guarantee from a solvent parent or director changes that equation.
Step-in rights and assignment rights. Draft the contract to give you the right to step in and take over the builder’s role if they fail, or to assign the contract to a replacement builder. This allows you to engage subcontractors directly, use the builder’s materials, and keep the project moving without terminating and re-tendering. These clauses are not standard, but they are negotiable.
Project bank accounts or trust accounts. In some states, you can require retention money and progress payments to be held in a project trust account. This ring-fences the money and protects it from the builder’s general creditors. It costs nothing to include this requirement in the contract, and it can save you significant loss if the builder fails.
Tighter payment milestones. Do not agree to large upfront deposits or progress payments for work not yet done. Structure the payment schedule so that you pay for value delivered, not value promised. If the builder asks for a 20% deposit before starting work, question why. A financially stable builder should not need that much upfront capital.
Insurance. If the project is high-risk or high-value, consider taking out contract works insurance that includes cover for builder insolvency. These policies are not cheap, but they transfer the risk to an insurer. If the builder fails, the insurer pays to complete or rectify the work.
Monitor financial health during the project. Do not assume that because the builder was solvent when you signed the contract, they will remain solvent. Watch for warning signs: late payments to subcontractors, requests to accelerate payment milestones, subcontractors walking off site, quality deterioration. If you see these signs, engage early. Ask direct questions. If necessary, suspend payments until you are satisfied the builder is solvent and performing.
None of these steps guarantee you will avoid builder insolvency. But they reduce your exposure, give you more control, and make recovery easier if it does happen.
The time to negotiate security, guarantees, and protective clauses is before you sign the contract, not after the builder has failed. Once the contract is signed, you live with the risk allocation you agreed to.
Final Thoughts: Keeping Control When a Contractor Collapses
Builder insolvency mid-project is expensive, disruptive, and stressful. You will lose time. You will lose money. You may lose faith in the construction process altogether.
But you can limit the damage.
The principals who manage this situation well are the ones who move quickly but carefully. They secure the site, read the contract, document everything, and get advice before acting. They do not assume the materials on site are theirs. They do not terminate without following the process. They do not pay twice unless they have to.
They accept that recovery from the liquidator is unlikely, and they focus instead on finishing the project efficiently with a replacement builder. They budget for cost escalation and delay. They communicate transparently with stakeholders.
And when they start the next project, they build in protections: security, guarantees, trust accounts, and better due diligence.
Contractor failure is now a normal part of the construction landscape. The question is not whether it will happen, but whether you are prepared when it does.
If your builder has just become insolvent and you are reading this because you do not know what to do next, here is the short version: secure the site, read your contract, document the position, get advice on termination, and start planning for completion with a new builder. Do not wait. Do not assume it will resolve itself. Act now.
And if you are planning a project and wondering whether your contract and your builder are robust enough, ask yourself this: if this builder collapsed tomorrow, do I have security, guarantees, and contractual protections that would allow me to finish the project without catastrophic loss?
If the answer is no, fix it before you break ground.
Litigation is complex, yes. But the pathway through builder insolvency does not have to be a disaster. With the right approach, you can keep control of your project, limit your losses, and get the building finished.
