Progress payments are a fundamental part of construction, but for a property developer, they are about much more than simply paying the builder as the project moves forward.
Every payment affects project cash flow, development finance and, importantly, the developer’s financial exposure if something goes wrong.
That is why progress payments in property development need to be carefully structured, assessed and documented throughout construction.
The rule is straightforward:
Pay for progress — not promises.
What Are Progress Payments in Property Development?
Progress payments are staged payments made to a builder or contractor as construction work is completed.
For residential developments, payments may be linked to defined construction milestones such as:
Deposit
Base or slab
Frame
Lock-up
Fixing or fit-out
Practical completion
Larger developments often use monthly progress claims instead, with the builder claiming for the value of work completed during that period.
Whichever method applies, the principle should remain the same: the payment should reflect work completed and the builder’s entitlement under the construction contract.
How Does a Progress Payment Work?
The payment process should be established before construction starts.
The building contract should clearly identify when progress claims can be submitted, how they will be assessed, payment timeframes and how variations, retention and other adjustments will be treated.
A typical process looks like this:
Builder submits claim → Work is assessed → Claim is adjusted where necessary → Amount is certified → Developer pays
The assessment stage is where developers need to pay attention.
A builder’s progress claim may include incomplete work, materials, variations, provisional amounts or other costs requiring verification.
Receiving an invoice does not automatically mean the entire amount claimed should be paid.
The Biggest Risk: Paying Ahead of Construction
One of the most important principles of construction progress payments is ensuring the amount paid does not get ahead of the actual value delivered on site.
Consider a $4 million construction contract.
If $2.8 million has already been paid but the genuine value of completed work is substantially lower, the developer may be overexposed.
If the builder subsequently experiences financial difficulty, becomes insolvent or abandons the project, another contractor may need to be engaged to complete the works.
The developer could effectively end up paying twice for part of the construction.
This is why developers should continually monitor:
Contract value → Work completed → Amount claimed → Amount certified → Amount paid → Cost to complete
A development can appear to be progressing well physically while becoming financially vulnerable behind the scenes.
Progress Claims Should Be Properly Assessed
Developers should not simply rely on the builder’s assessment of their own progress.
Depending on the project and construction contract, progress claims may be assessed by a Superintendent, Contract Administrator, Quantity Surveyor or other appropriately appointed professional.
The assessment may consider:
Actual work completed
Previous progress payments
Approved variations
Provisional sums
Materials claimed
Retention or security
Incomplete or defective work where relevant
Remaining cost to complete
The objective is not to unnecessarily reduce what the builder receives.
Builders need reliable cash flow to pay trades, purchase materials and continue construction.
The objective is to ensure the builder receives what they are contractually entitled to — without the developer paying ahead of the work.
Variations and Progress Payments
Variations can quickly make progress claims difficult to understand.
Once numerous variations are added to the original contract sum, developers can lose visibility over what has been approved, what has been paid and what the project's final construction cost is becoming.
Variations should therefore be clearly documented and, where possible, identify:
The scope of the change
Reason for the variation
Cost
Builder's margin
Time implications
Approval status
Good variation management and good progress payment management go hand in hand.
If variations are poorly controlled, construction costs can drift significantly from the original development feasibility.
Progress Payments and Construction Finance
For financed developments, another layer is added to the process.
Before releasing a construction loan drawdown, a lender may require an inspection, valuation or Quantity Surveyor's report confirming construction progress.
Developers need to understand that the lender and builder have different relationships with the project.
The construction contract is generally between the developer and builder. A delay in the financier releasing funds does not necessarily remove the developer's contractual obligation to pay the builder.
The proposed progress payment schedule should therefore be reviewed alongside the project's financing arrangements before the construction contract is signed.
Retention and Security
Depending on the construction contract, retention or another form of security may also provide protection for the developer.
Rather than paying 100% of certain amounts immediately, part may be retained and subsequently released according to the contractual mechanism.
Other projects may use bank guarantees or alternative forms of security.
These provisions need to be understood from the beginning because they can become particularly important when dealing with defects, incomplete obligations or contractor default.
Be Careful With the Final Progress Payment
The final payment is one of the most important payments on the project.
Practical completion may trigger several contractual consequences, potentially including payment obligations, release of security, commencement of the defects liability period and handover of the project.
Before making the relevant payment, developers should ensure the works have been properly inspected and that the contractual requirements for practical completion have genuinely been satisfied.
Almost complete and practically complete are not necessarily the same thing.
Don't Ignore Security of Payment Requirements
Property developers should also understand the Security of Payment legislation applying in their state or territory.
A formal payment claim can trigger strict statutory deadlines and response requirements.
If a developer disagrees with a claim, simply ignoring it can create unnecessary contractual and legal risk.
Claims should be reviewed promptly, with the appropriate contractual or statutory response prepared where required.
Why Independent Contract Administration Matters
For larger developments, having someone independently administering progress claims can significantly improve financial control.
A properly appointed Superintendent or Contract Administrator can assess the builder's claim against actual site progress and the requirements of the construction contract.
This creates greater discipline around progress payments, variations, completion and project documentation.
More importantly, it gives the developer a clearer picture of a fundamental question:
Does the money leaving the project reflect the value actually being delivered?
Final Thoughts
Progress payments keep construction moving, but they also progressively transfer money — and financial leverage — from the developer to the builder.
They should therefore never become an automatic accounting exercise.
Successful progress payment management in property development requires developers to understand what has been completed, what has been claimed, what the contract requires and what remains to finish the project.
Builders should be paid fairly and on time for work properly completed.
But developers should maintain the same discipline with every claim:
Pay what is properly due. Pay it on time. But never let your payments get ahead of your project.
Frequently Asked Questions
What are progress payments in property development?
Progress payments are staged payments made to a builder as construction reaches agreed milestones or a specified value of work is completed. They allow construction costs to be paid progressively rather than upfront.
Should a developer automatically pay a builder’s progress claim?
No. A progress claim should be assessed against the construction contract and the actual work completed before payment is made. The amount claimed and the amount properly payable may not always be the same.
What happens if progress payments get ahead of construction?
Paying ahead can expose the developer financially. If the builder defaults, becomes insolvent or abandons the project, there may not be enough unpaid contract value remaining to complete the works with another contractor.
Who should assess construction progress claims?
Depending on the contract and project, progress claims may be assessed by a Superintendent, Contract Administrator, Quantity Surveyor or other appropriately appointed professional to verify progress and contractual entitlement.
How do variations affect progress payments?
Approved variations can increase or decrease the contract value and may be incorporated into progress claims. Developers should maintain clear records of each variation, its cost, approval status and payments made to maintain control over the project's final construction cost.
