Ask a developer what a quantity surveyor report is and you will often get one answer, when there are really two products with almost nothing in common. The first is a one-off assessment of your building contract and budget, written before a lender commits. The second is a recurring certificate issued through construction, usually monthly, that decides how much of your facility gets released this month. Same profession, same firm in many cases, different scope, different timing, and very different consequences when it goes wrong.
The cost plan sits with your quantity surveyor and the drawdown mechanics sit in your facility agreement. Between them they decide when money leaves your account and when money arrives in it. This guide covers what each report contains, where each sits in the programme, how a progress certificate interacts with the security of payment legislation in your state, what the reports tend to cost, and the questions worth putting to your quantity surveyor before you engage one.
Figures, timeframes and legislative references below were current at the date of writing and do change. Each linked primary source is the place to confirm the position that applies to your project.
What is a quantity surveyor report?
A quantity surveyor report is an independent assessment of construction cost or construction progress, prepared by a cost professional who acts for whoever engaged them. That last part matters more than anything else in this guide. The report is a product of an engagement, and the engagement determines whose interests the report is written to protect.
Developers generally meet the profession in three separate settings:
- Cost planning for you. Order of cost estimates, elemental cost plans, tender reviews and value management, engaged by you or by your project manager to work out whether a scheme is buildable within budget. This is covered separately in the quantity surveyor cost estimation guide.
- Reporting for a lender. An initial cost report before financial close, then progress certificates through construction. The lender appoints the consultant, the report is addressed to the lender, and you usually pay for it.
- Reporting for the tax return. A capital works estimate, sometimes called a depreciation schedule, prepared after practical completion where you hold rather than sell. Different product again, covered further down.
The two reports this guide focuses on are the second group, because they are the ones that gate money. The Australian Institute of Quantity Surveyors sets standards of practice for the profession and publishes the Australian Standard Method of Measurement, which is the measurement convention most cost plans in Australia are built on. There is no single statutory form for either report, so scope is set by the engagement letter, and scope is where most disputes start.
What is an initial cost report, and what does the lender use it for?
An initial cost report is an independent review of your building contract, your project budget and your programme, prepared before a construction facility settles, so the lender can decide whether the numbers you have given them will actually deliver the building.
It goes by several names depending on who is writing the engagement letter: initial cost report, initial quantity surveyor report, financier’s report, or a pre-construction report. The label does not change what the lender is buying, which is an opinion from someone the borrower does not control.
What an initial cost report typically covers
Scope varies, but a report prepared for a development facility will commonly work through:
- The building contract. Contract type, contract sum, whether the sum is fixed or subject to rise and fall, the schedule of rates, provisional sums and provisional quantities, and prime cost items. The report generally comments on whether the sum looks fair and reasonable against comparable projects.
- Documentation completeness. How far the design has progressed, what is still to be resolved, and which items are carrying a provisional sum precisely because nobody has designed them yet. Thin documentation at contract signing is one of the most reliable predictors of variation pressure later.
- The budget outside the contract. Consultant fees, authority and headworks charges, site costs, connections, and anything the builder is not carrying. This is where a project budget and a building contract commonly diverge, and where a lender’s total development cost can land above the developer’s.
- Contingency. Whether the allowance is adequate for the contract type, documentation maturity and site risk. Lenders often form their own view on the required construction contingency and set it above the developer’s figure.
- Programme. Whether the construction period is achievable, what the critical path looks like, and whether the programme sits inside the facility term with room to spare.
- The builder. Capacity, current workload, financial capability and track record on comparable work, which overlaps with your own process for choosing a builder.
- Cashflow. A drawdown forecast the lender can set its facility against.
Why the lender orders the report rather than you
Because the value of the report to the lender is precisely that you did not write it. A cost plan you commissioned, however well prepared, is a document produced for the borrower. A report addressed to the financier, with a duty of care owed to the financier, is evidence they can act on.
The practical consequence is that you may pay for a report you do not control and, on some engagements, do not automatically receive. Whether you get a copy, whether you can rely on it, and whether the consultant owes you anything at all are questions answered in the engagement letter rather than in general practice. Where a developer has already paid for their own cost plan, some lenders will accept a reliance letter extending the existing consultant’s duty of care to the financier instead of commissioning a fresh report, though this tends to depend on who prepared the original and how recent it is.
The initial report also has a habit of changing the deal. If the assessed contract sum, contingency or programme differ from what went into the credit submission, the lender’s total development cost changes, and so does the equity contribution required before the first drawdown. That is a repricing event discovered late, and it is worth building into your timeline rather than your assumptions.
What is a progress certificate, and when is one issued?
A progress certificate is a periodic, usually monthly, certification of the value of work properly completed on site to a given date, prepared for the lender so it can release the next tranche of a construction facility.
The rhythm on most projects runs like this. The builder submits a progress claim under the building contract. The superintendent or contract administrator assesses it under the contract. Separately, the lender’s quantity surveyor inspects the site, assesses the claim against actual physical progress, adjusts it where the claim runs ahead of the work, and issues a certificate to the lender. The lender releases funds against the certificate, subject to the conditions in the facility agreement. Those conditions and the mechanics of the release are covered in the guide to construction loan drawdowns.
Note the two separate assessments. The certificate that governs your loan and the certificate that governs your contractual payment obligation are not necessarily the same document, are not necessarily issued by the same person, and are not necessarily for the same amount. That gap is where developer cashflow pain generally lives.
What happens during the site inspection
The consultant walks the site, compares what has physically been built against the claim, and forms a view on the percentage of each trade or element genuinely complete. Beyond the walk, a progress certificate will commonly deal with:
- Materials on site and off site. Whether unfixed materials are included, whether title has passed, and whether off-site materials are covered by vesting or by a bond.
- Variations. Which variations have been approved, which are claimed but not yet agreed, and what the running total is doing to the contract sum.
- Retention or security. What is being held, and against what.
- Programme. Actual progress against the construction programme, and whether the practical completion date still looks achievable. This is where an early view of delay usually surfaces first, well before anyone issues a formal notice.
- Quality and compliance observations. Generally limited, and generally not a substitute for a building surveyor or a defects inspection.
Cost to complete: the number that actually governs the facility
The percentage complete figure gets the attention, but the number that tends to drive lender behaviour is the estimated cost to complete: what it would now take, from today, to finish the building.
A facility is usually sized so that undrawn funds plus remaining equity are enough to complete. If the cost to complete rises above what remains available, the facility is out of balance, and the standard consequence is that the borrower tops up equity before further drawdowns are released. The certificate is where that gets picked up, which is why an unremarkable-looking monthly report can turn into a capital call.
The lever is that cost to complete moves for reasons other than overspending. Unapproved variations, provisional sums running above allowance, prolongation, and a shrinking contingency all push it up while the physical percentage complete looks perfectly healthy. Tracking it in your own development cashflow between certificates, rather than learning it from the certificate, tends to be the difference between a conversation and a surprise.
How do the two reports differ?
| Initial cost report | Progress certificate | |
|---|---|---|
| Timing | Once, before financial close | Monthly through construction |
| Question answered | Is the contract sum and budget reasonable, and is the programme achievable? | What has been built, what is it worth, and what will it cost to finish? |
| Primary audience | The lender’s credit team | The lender’s facility manager |
| Typical trigger | Credit approval condition precedent | Builder’s progress claim |
| What it can change | Total development cost, contingency, equity required at settlement | Amount released this month, whether the facility remains in balance |
| Site visit | Sometimes, often desktop with a site inspection | Almost always |
| Main developer risk | A reassessed budget that moves the deal after you have committed | A certificate for less than you claimed, creating a funding gap against the builder’s payment date |
The distinction that trips people up is that the initial report is an opinion on a forecast, while a progress certificate is an assessment of a fact. You can argue about the first with evidence and comparables. You have much less room to argue about the second, because the consultant has stood on the slab.
Where do the reports sit in the development programme?
Sequence matters more than most developers plan for, because two of these reports sit on the critical path to money.
Feasibility and acquisition. An order of cost estimate or a preliminary cost plan, engaged by you. No lender involvement. This is where a rate per square metre carries most of the weight, and where the construction cost per square metre you use can quietly decide whether a site looks viable.
Design development and Development Application (DA). Elemental cost plans updated as the design resolves. Useful for value management before documentation gets expensive to change.
Tender and contract. A tender review or contract sum analysis, engaged by you. If you intend to seek development finance, briefing this work so that it is capable of supporting a later lender engagement can save a duplicated exercise.
Credit approval to financial close. The initial cost report. This one is on the critical path. It is commissioned after credit approval in principle and before settlement, and a report that returns unfavourably at this point can move settlement dates that are already contractual.
Construction. Monthly progress certificates, running for the whole build period, plus a final certificate at practical completion in most engagements.
Post-completion. A capital works estimate if you are holding the asset. Not on anyone’s critical path, but easier and cheaper to produce while the construction records are still assembled.
The trap is treating the initial report as a formality booked in the same week as settlement. Turnaround depends on documentation quality and site access, and the report cannot be finalised against a building contract that is still being negotiated.
How does a progress certificate interact with security of payment legislation?
A quantity surveyor’s certificate to a lender has no standing under the security of payment legislation, and does not extend the statutory clock for responding to your builder’s payment claim. The claim and schedule mechanics themselves are covered in the guide to the Security of Payment Act.
This is the single most useful thing on this page. Every state and territory has a statutory payment regime. Where a builder serves a valid payment claim, the party liable to pay generally has a fixed number of business days to serve a payment schedule setting out what it proposes to pay and why. Miss the window, and the consequences can include becoming liable for the full claimed amount, with limited scope to run reasons for withholding that were not in the schedule.
The lender’s quantity surveyor works to the facility agreement and to their own engagement, not to that statutory clock. If the certificate lands after your statutory deadline, the deadline still applies. Aligning the claim date in the building contract, the certification cycle in the facility agreement, and the statutory response period is a contract drafting question worth raising before the contracts are signed, not after the first claim arrives.
The timeframes and mechanics differ by jurisdiction.
New South Wales
The Building and Construction Industry Security of Payment Act 1999 applies. New South Wales government guidance on responding to a payment claim states that a payment schedule must reach the claimant within 10 business days after the payment claim is received. Guidance on making a payment claim notes that only one claim may be made for each reference date, being the date stated in the contract or, where the contract is silent, the last day of each month. Published due dates for payment vary by the claimant’s position in the contracting chain.
Victoria
The Building and Construction Industry Security of Payment Act 2002 applies, and it has changed materially. The Building and Plumbing Commission states that amendments made by the Building Legislation Amendment (Fairer Payments on Jobsites and Other Matters) Act 2025 took effect from 15 April 2026.
The changes the Commission lists include the removal of the dual concepts of claimable variations and excluded amounts, replacement of reference dates with a monthly entitlement to claim, an extension of the time to make a payment claim from three months to six months, payment and release terms capped at 20 business days, new notice-based time bar restrictions, and a change to the definition of business day to exclude 22 December to 10 January. The Commission also states that the changes affecting construction contracts apply to all construction contracts, including those entered into before the amendments came into operation.
If your Victorian project was documented before April 2026 and is still running, the payment provisions in that contract may not read the way they operate now. That is a question for your construction lawyer rather than your quantity surveyor.
Queensland
The Building Industry Fairness (Security of Payment) Act 2017 applies. The Queensland Building and Construction Commission states that where you do not intend to pay the full claimed amount by the due date, you must give the claimant a payment schedule within 15 business days after being given the payment claim, or earlier if the contract states another timeframe, and that a payment schedule must state all reasons for paying less or withholding payment. Queensland also operates a statutory trust regime over parts of the contracting chain, which changes how retention and progress money is held rather than how it is certified.
Western Australia and the Northern Territory
Both operate a different model to the eastern states, built around adjudicating payment disputes rather than a claim and schedule cycle.
In Western Australia, the Building and Construction Industry (Security of Payment) Act 2021 applies to construction contracts entered into from 1 August 2022, with contracts entered before that date continuing under the former 2004 legislation. The state’s security of payment guidance sets out the staged reforms, which included a retention trust scheme introduced in phases.
In the Northern Territory, the Construction Contracts (Security of Payments) Act 2004 applies. Northern Territory government guidance on contracts with missing or invalid provisions states that a provision requiring payment more than 50 days after the payment is claimed must be read as amended to require payment within 28 days after it is claimed.
South Australia, Tasmania and the Australian Capital Territory
All three operate claim and schedule regimes broadly modelled on the New South Wales approach, with their own timeframes and thresholds: the Building and Construction Industry Security of Payment Act 2009 (SA), the Building and Construction Industry Security of Payment Act 2009 (Tas), and the Building and Construction Industry (Security of Payment) Act 2009 (ACT). The response periods in these three jurisdictions are not identical to each other or to New South Wales, and residential work is treated differently in some of them, so the specific number of business days is worth confirming against the Act that governs your contract rather than assumed from an interstate project.
Who issues the certificate under a standard form building contract?
Under most standard form contracts the superintendent issues the progress certificate that binds the parties, and the lender’s quantity surveyor issues a separate certificate that binds nobody but informs the lender. What the superintendent does and who can hold the role is covered in the guide to the contract administrator and superintendent. Confusing the two is a recurring and expensive mistake.
Standards Australia updated AS 4000 in 2025, the first significant revision of the general conditions of contract in almost three decades, with simplified drafting, consolidated definitions and alignment to changes in law since 1997, while keeping the underlying risk allocation. Under this family of contracts the superintendent assesses the contractor’s progress claim and certifies an amount, and the certificate triggers the principal’s payment obligation. The certificate is generally provisional and on account. It is not an acceptance of the work, and it does not stop the principal bringing a claim for defective work later.
Two structures are common in practice. On smaller projects the same firm may act as both superintendent and lender’s quantity surveyor, which is efficient but places one consultant in two roles with different duties. On larger projects the roles are separated, and the developer sits between two assessments that may disagree. Which arrangement applies to you is set in the building contract and the facility agreement, and the interaction between the two documents is worth reading together rather than separately. The contract type also changes what there is to certify: a guaranteed maximum price contract and a lump sum contract produce very different variation and provisional sum reporting.
What do quantity surveyor reports cost, and who pays?
Fees are set by the market rather than by any published scale, so what follows is indicative market practice rather than a rate you can rely on. A quote against your actual scope is the only figure that means anything.
Broadly, three pricing models are common. Percentage fees against construction value are typically quoted somewhere in the range of half a per cent to two per cent for full cost management engagements, moving with project size and complexity, and the percentage generally falls as project value rises. Fixed fees are common for a defined deliverable such as an initial cost report. Hourly rates apply to advisory and dispute work.
For a one-off initial cost report on a mid-sized residential project, fixed fees in the low thousands to low tens of thousands of dollars are commonly quoted, moving with the contract sum, documentation quality and turnaround. Progress certificates are often priced per certificate or as a monthly retainer for the construction period, so the total is a function of your programme length as much as your project size. A twelve month build and an eighteen month build with the same contract sum can carry meaningfully different monitoring cost.
Who pays is usually simple: you do. The lender appoints the consultant, and the facility documents generally make the borrower responsible for the cost, either paid directly or capitalised into the facility. Two things are worth checking in the facility documents before signing. First, whether the fee is capped or open-ended, since a project that runs long will generate certificates for as long as it runs. Second, what happens if the lender requires a further report after a variation, a delay or a change in market conditions.
For feasibility purposes these fees sit in professional fees within total development cost, and the monitoring component is better modelled as a monthly line across the construction period than as a single lump at financial close, because that is how it is actually incurred.
A worked example: reports across a 24-unit townhouse project
All figures below exclude Goods and Services Tax (GST) and are illustrative only.
A developer is taking a 24-unit townhouse project to a construction facility.
| Line | Amount |
|---|---|
| Gross realisation, 24 units at $1,050,000 | $25,200,000 |
| Building contract sum | $12,600,000 |
| Professional fees and consultants | $1,050,000 |
| Statutory and authority costs | $620,000 |
| Finance costs | $1,180,000 |
| Selling and marketing, 3 per cent of gross realisation | $756,000 |
| Contingency, 5 per cent of contract sum | $630,000 |
| Costs excluding land | $16,836,000 |
| Land and acquisition costs | $4,520,000 |
| Total development cost | $21,356,000 |
| Development profit | $3,844,000 |
| Margin on total development cost | 18.0 per cent |
The initial cost report comes back with two adjustments. The consultant assesses two trade packages as under-priced against comparable projects and recommends an additional allowance of $480,000 against the contract sum. The lender adopts that reassessment and applies its 5 per cent contingency to the reassessed sum of $13,080,000, lifting contingency by $24,000 to $654,000.
Nothing about the scheme has changed. No variation has been issued, no design has moved, and the builder has not asked for anything. Only the assessment has changed.
| Line | Original | After initial cost report |
|---|---|---|
| Costs excluding land | $16,836,000 | $17,340,000 |
| Land and acquisition costs | $4,520,000 | $4,520,000 |
| Total development cost | $21,356,000 | $21,860,000 |
| Development profit | $3,844,000 | $3,340,000 |
| Margin on total development cost | 18.0 per cent | 15.3 per cent |
If the lender sizes the facility at 65 per cent of total development cost, the debt line moves from $13,881,400 to $14,209,000 and the equity requirement moves from $7,474,600 to $7,651,000, an additional $176,400 to be found before the first drawdown. The margin has fallen by 2.7 percentage points and the equity has risen by roughly $176,000, on a report the developer commissioned and paid for. The relationship between cost and the funding line is set out further in the guide to loan to cost ratio.
The point is not that the consultant was wrong. It may well be that the two trade packages were under-priced and the report saved the project a mid-build blowout. The point is that this outcome arrives after credit approval, close to settlement, and is worth carrying as a scenario in the feasibility rather than as a possibility nobody modelled.
Is a tax depreciation schedule the same thing?
No. A capital works estimate prepared for a tax return is a separate engagement, produced after the building is finished, for an entirely different purpose.
Where a developer holds the completed asset rather than selling it, deductions for capital works may be available under Division 43 of the Income Tax Assessment Act 1997. The Australian Taxation Office (ATO) guidance on working out capital works deductions sets out the basic mechanics.
The connection to quantity surveying comes from Taxation Ruling TR 97/25, which addresses how construction expenditure is established. Where actual construction expenditure cannot be determined, the Australian Taxation Office (ATO) accepts an estimate from an appropriately qualified person, and a quantity surveyor with expertise in the relevant type of construction is among those the ruling identifies. The ruling also indicates that published building cost guides are not accepted for estimating actual construction cost unless used merely as a guide by an appropriately qualified person, since a rate per square metre drawn from industry averages is not specific to the building being assessed.
For a developer who has built the asset, actual construction expenditure is usually well documented, so the estimating question may not arise in the same way it does for a purchaser of an existing building. What tends to matter more is the split between capital works and plant and equipment, and the treatment of costs that are neither. Those are questions for your accountant, and the interaction with a build-to-hold strategy is covered in the guide to Division 43 depreciation for build-to-hold developers.
Two practical notes. Assembling the schedule is materially easier while the construction records, contract, variation register and final account are still to hand. And the firm that monitored the build for your lender is not automatically the right firm for the tax work, because the skill sets and the client relationship are different.
Does a quantity surveyor have to be registered?
It depends on the state, and the position is less uniform than most developers assume.
In Victoria, quantity surveyor is a registration category for building practitioners. The Australian Business Licence and Information Service records that a registration of building practitioners as a quantity surveyor is required to estimate and monitor construction costs for all classes of building and types of construction, applying knowledge of construction methods and materials from concept design to completion. The registration is administered by the Building and Plumbing Commission under the Building Act 1993 and the Building Regulations 2018, and is renewed annually.
No equivalent standalone statutory registration category for quantity surveyors appears in the other states and territories. In practice, where there is no statutory registration, professional standing tends to rest on membership of the professional body and on certification. The Australian Institute of Quantity Surveyors certifies practitioners and publishes the standards of practice and code of conduct its members are bound by, and its certified grade requires an assessment of professional competence.
Two things follow for a developer. First, checking Victorian registration is a straightforward search, and worth doing on a Victorian project. Second, in every jurisdiction the more useful checks are professional indemnity insurance at a level proportionate to your project value, demonstrated experience in your building type and procurement route, and whether the individual signing the report is the individual who inspected the site.
How do quantity surveyor reports work in New Zealand?
The commercial mechanics are similar and the statutory framework is different.
New Zealand development lenders generally require the same two products: an initial assessment of the contract and budget before drawdown, and periodic certification through construction. The Construction Contracts Act 2002 governs payment claims and payment schedules. Where the contract does not provide otherwise, a payment schedule must be provided within 20 working days after the payment claim is served, and a progress payment becomes due and payable 20 working days after a payment claim is served. The Ministry of Business, Innovation and Employment publishes guidance on the Act, and quantity surveying work falls within the definition of construction work under it.
The same timing point applies as in Australia. A certificate prepared for a lender does not alter the statutory response period, and where a contract sets shorter timeframes than the default, the contract governs.
Professionally, the New Zealand Institute of Quantity Surveyors administers the Registered Quantity Surveyor designation and maintains a directory of registered practitioners. As in most of Australia, that registration is a professional credential rather than an occupational licence.
How do the reports flow into your feasibility?
Three places, and only one of them is obvious.
The cost line. The reassessed contract sum and the lender’s contingency, not your own figures, are what the facility is sized against. Carrying the lender’s view as a scenario alongside your base case tends to be more useful than discovering it at credit committee.
The timing line. Progress certificates set the shape of your drawdown curve. A facility that is only released against certified progress means your funding follows the build rather than leading it, which affects when interest starts accruing and how much working capital you carry between certificate and release. Building the certification lag into your cashflow, rather than assuming funds arrive on the claim date, is generally closer to how the money moves.
The equity line. Cost to complete is the mechanism through which a construction overrun becomes an equity call. Because it is assessed monthly by someone outside your business, it is one of the few project risks with a fixed reporting cycle. Modelling how much headroom sits between undrawn funds and cost to complete, and watching what erodes it, gives you the warning the certificate itself will not.
What to ask your quantity surveyor
Before you engage, or before you accept a lender’s appointee:
- Who is the client on this engagement, who does the duty of care run to, and will I receive a copy of the report?
- What is expressly excluded from scope? Are authority contributions, headworks, site remediation and connection costs in or out?
- What documentation set is the assessment based on, and what happens to the assessment when the design develops further?
- How will provisional sums, provisional quantities and prime cost items be treated, and how will you flag one running above allowance?
- What is the turnaround from site inspection to issued certificate, and what triggers a delay?
- How will cost to complete be calculated, what does it assume about outstanding variations, and will you flag it before the facility goes out of balance?
- Who physically inspects the site, and is that the same person who signs the certificate?
- What is your professional indemnity insurance limit, and does it sit sensibly against this contract sum?
- What are the total fees for the construction period, are they capped, and what triggers an additional fee?
- If we disagree with an assessment, what is the process for putting evidence to you, and what is the timeframe?
What to ask your construction lawyer
- Do the payment claim dates in the building contract, the certification cycle in the facility agreement, and the statutory response period in our state actually align?
- What is our exposure if a lender’s certificate arrives after the statutory deadline for serving a payment schedule?
- Which document governs if the superintendent’s certificate and the lender’s certificate disagree, and what do we pay in the meantime?
- What does the facility agreement say about who bears the cost of additional reports, and is that liability capped?
- For our Victorian contract signed before April 2026, which of the amended provisions now apply to it, and what changes in practice?
- Can the lender’s consultant be replaced, and on whose decision?
What to ask your accountant
- Given our hold or sell strategy, is a capital works estimate worth commissioning, and at what point?
- How should the split between capital works and plant and equipment be approached for this building type?
- Are the fees for the initial report and the progress certificates treated as a cost of the project or as a finance cost, and does that treatment affect our position?
- What construction records should we be retaining now to support a capital works claim later?
Key takeaways
- Initial cost reports and progress certificates are two different products. One assesses a forecast before financial close, the other assesses a fact every month through construction.
- The lender appoints the consultant, the report is written for the lender, and you generally pay for it. What you receive and what you can rely on are set in the engagement letter.
- Cost to complete, not percentage complete, is what usually determines whether a facility stays in balance and whether you face an equity call.
- A quantity surveyor’s certificate to a lender does not extend the statutory clock for responding to a payment claim under your state’s security of payment legislation. Victoria’s regime changed materially from 15 April 2026, and the Commission states the contract-related changes apply to contracts entered into before that date.
- Under standard form contracts the superintendent’s certificate is what binds the parties. The lender’s certificate binds nobody but decides what you can draw.
- Victoria registers quantity surveyors as a class of building practitioner. Elsewhere in Australia, and in New Zealand, standing tends to rest on professional certification rather than an occupational licence.
