Compliance, insurance & legal — related to our QS services
Banks typically require contract works insurance to cover the build during construction, along with public liability cover from the builder. They may also want to see evidence of builder guarantees and, once the home is complete, standard house insurance. Your lender or broker can confirm the exact requirements for your situation.
In most cases, yes. Banks usually want to see that building consent has been granted before they fully commit to funding the construction. This reduces the risk of design or compliance issues that could delay or prevent the build. Some lenders may offer conditional approval earlier, but final drawdowns generally depend on consent being issued.
The bank will usually require a Code Compliance Certificate before converting your construction loan to a standard home loan or releasing any final retention amounts. The CCC confirms that the work complies with the Building Code and consent. Without it, the bank may view the property as incomplete and higher risk.
If a dispute arises, it is important to review the building contract, keep clear records, and seek advice early. Banks generally do not get involved in contractual disputes but may pause or adjust funding if the project stalls. A quantity surveyor can help assess the value of work completed and variations, which can be useful in resolving disagreements.
Yes. A quantity surveyor can assist with cost planning, progress claims, variation assessments, and documentation that banks and lawyers rely on. By keeping costs transparent and well documented, a QS helps you meet lender conditions and reduces the risk of disputes. This support is especially valuable on larger or more complex projects.

Loan eligibility & pre-approval — related to our QS services
Most banks in New Zealand expect at least a 20 percent deposit for an owner occupied construction loan, although this can vary by lender and by your overall financial position. For investment properties, the required deposit is often higher. The exact percentage can also depend on the location, type of build, and how strong your income and credit profile are.
Yes, a professional quantity surveyor report can significantly strengthen a loan application. It gives the bank confidence that the build costs have been independently checked and are realistic for the scope of work. This reduces the risk of cost overruns and helps the lender assess whether the project is viable within your budget and borrowing capacity.
Most New Zealand banks issue pre approvals that are valid for around 60 to 90 days, but this can vary by lender. If your circumstances change or the project details shift significantly, the bank may need to reassess your application. It is a good idea to check the expiry date on your pre approval letter and talk to your lender or broker if you are getting close to that date.
It is sometimes possible, but not guaranteed. If the final quantity surveyor estimate is higher than the bank initially assumed, the lender may ask you to increase your deposit, reduce the scope of the project, or provide additional security. In some cases the bank may decline or reduce the loan amount if the project no longer fits within their risk settings.
Loan eligibility and pre approval — related to our QS services
Most New Zealand banks require proof of income, recent bank statements, a summary of assets and liabilities, and details of any existing lending. For construction loans they also require building consent, a signed building contract, and a detailed cost estimate prepared by a quantity surveyor. Some lenders may also request payslips, IRD summaries, and evidence of your deposit or equity position.
Most banks in New Zealand expect a deposit of around twenty percent for an owner occupied construction loan. Investment properties often require a higher deposit. The exact amount depends on the lender, the type of build, and your overall financial position.
A quantity surveyor report can strengthen a loan application because it provides an independent assessment of the expected construction cost. Banks rely on this report to confirm that the project budget is realistic and that the lending amount is appropriate for the scope of work.
Most banks issue pre approvals that remain valid for sixty to ninety days. If your circumstances change or the project details are updated, the bank may reassess your application. It is important to check the expiry date on your pre approval letter.
It is sometimes possible, but not guaranteed. If the final quantity surveyor estimate is higher than the bank expected, the lender may request a higher deposit, additional security, or changes to the project scope. In some cases the bank may reduce or decline the loan amount.
Progress payments & drawdowns — related to our QS services
With a construction loan, the bank usually releases funds in stages rather than paying the full amount upfront. These stages often align with milestones such as foundations, framing, closed in, and completion. A quantity surveyor or valuer may be asked to confirm that the work claimed has been completed before each drawdown is approved.
Banks use progress claim reports to verify that the value of work completed on site matches the amount being claimed. This protects both you and the lender from overpayment or paying ahead of actual progress. A QS will review the contract, variations, and site progress, then certify a fair value for the bank to release.
If the builder claims more than the QS believes has been completed, the bank will usually rely on the QS assessment. You may need to discuss the difference with your builder and agree on a revised claim. In some cases, documentation or site evidence can resolve the gap. The goal is to ensure payments fairly reflect actual progress.
You can sometimes pay minor items directly, but for a construction loan the bank generally expects to control the main progress payments. If you pay large amounts outside the agreed drawdown process, you may affect the bank’s security position and your own cash flow. It is important to discuss any direct payments with your lender before proceeding.
If costs increase during construction, you may need to contribute additional funds, adjust the scope, or seek an increase in lending. Banks are cautious about cost overruns and will want to see updated QS reports or revised contracts. Early communication with your lender and QS is crucial so that options can be explored before the project stalls.

Risk & lending conditions — related to our QS services
New builds carry additional risks such as cost overruns, delays, consent issues, and contractor failure. Banks factor these risks into their lending criteria and may require more documentation, higher deposits, or independent QS reports. Existing homes are easier to value and have fewer unknowns, so the risk profile is different.
Yes, in some circumstances banks can change conditions, especially if there are significant changes to the project, cost increases, or issues with repayments. They may request updated QS reports, revised contracts, or additional equity. While this is not common in well managed projects, it is important to keep your lender informed throughout the build.
Your credit history is a key part of the bank’s assessment. Even with a strong project and solid QS report, poor credit or past defaults can limit how much you can borrow or whether the bank will lend at all. It is wise to check your credit record early and address any issues before applying for a construction loan.
Yes. With turnkey contracts, the builder carries more of the construction risk and you usually pay on completion, so banks may treat the lending more like a standard mortgage. With progress payment contracts, the bank releases funds in stages and relies more heavily on QS or valuer reports. The structure of your contract can influence how the bank views risk.

Yes. With turnkey contracts the builder carries more of the construction risk, so banks may treat the lending more like a standard mortgage. Progress payment contracts require staged funding and QS involvement.
Valuations & QS reports — related to our QS services
A bank valuation focuses on the market value of the completed property, while a quantity surveyor cost estimate focuses on the cost to build it. The valuer looks at comparable sales, location, and market conditions. The QS looks at materials, labour, subcontractors, and construction methodology. Banks often use both together to assess risk and lending limits.
The best time to obtain a quantity surveyor report is once your plans and specifications are reasonably developed but before you finalise lending and sign fixed contracts. This allows the QS to price the project accurately and gives the bank confidence in the numbers. If you make major design changes later, an updated report may be required.
Banks generally prefer to see as few provisional and PC sums as possible, because they introduce uncertainty into the final cost. Some allowances are normal, especially for finishes or site works that are not fully defined, but large or numerous provisional sums may cause the bank to question the overall budget. A QS can help tighten these allowances where possible.
Not necessarily. The bank will consider the QS estimate alongside the valuation, your income, deposit, and overall risk profile. Even if the QS estimate is sound, the lender may cap the loan based on their internal policies, maximum loan to value ratios, or your servicing ability. The QS report informs the decision but does not guarantee a specific lending amount.

Progress claim basics — related to our QS services
A progress claim is a request for payment for work completed to a certain point in the project. It allows the builder to be paid in stages rather than waiting until the end of the job.
Progress claims are usually made monthly or at agreed milestones such as foundations, framing, and closing in. The timing is set out in the building contract.
The builder usually prepares the progress claim, and a quantity surveyor or valuer may be asked to review and certify it for the bank or owner.
Banks want progress claims certified to confirm that the value of work completed matches the amount being requested. This protects both the lender and the borrower from overpayment.
Yes. You can ask for clarification, request supporting information, or engage a quantity surveyor to review the claim before payment is made.
QS role in progress claims — related to our QS services
A quantity surveyor checks the contract, previous claims, variations, and work completed on site. They then assess a fair value for the current claim.
You may not need a QS for every claim on a small project, but for larger or bank funded projects regular QS involvement is common and often required.
Yes. A QS provides an independent view of the value of work completed, which can help resolve disagreements between owner and builder.
QS certification reduces the risk of disputes but cannot remove it completely. Clear contracts and good communication are also important.
No. Many owners engage a QS for their own peace of mind, even when the bank does not require it.
Retention and final claims — related to our QS services
Retention is a portion of each payment that is held back until the end of the project. It provides security that defects will be fixed.
Retention is usually released in two parts, at practical completion and after the defects liability period ends, provided defects are resolved.
A final claim is the last payment request that includes any remaining contract sum, agreed variations, and retention due for release.
It is often wise to have a QS review the final claim to confirm that all work and variations are correctly valued before final payment.
Yes. The parties can agree to reduce or remove retention, but this should be clearly recorded in the contract or a formal variation.
Under and over claiming — related to our QS services
Over claiming occurs when the value claimed is higher than the value of work actually completed. This can create cash flow and trust issues.
Under claiming occurs when the builder claims less than the value of work completed. This can strain the builder cash flow.
A QS compares the claimed amount with the work completed and the contract rates. This helps ensure that claims are fair and accurate.
Yes. Repeated over claiming may indicate poor financial management or pressure on the builder cash flow and should be taken seriously.
You should request more detail, compare the claim with site progress, and consider engaging a QS to review the claim.
Valuations and loan drawdowns — related to our QS services
For some projects, the bank uses valuations or QS reports to confirm that the property value or work completed supports the next loan drawdown.
An as completed valuation estimates the market value of the property once construction is finished. Banks use it to confirm that the completed project supports the lending amount.
The bank may request an updated valuation if the project scope changes, costs increase, or the build takes longer than expected.
Yes. If a valuation comes in lower than expected, the bank may reduce the loan amount or require additional equity.
A QS report supports a valuation by confirming realistic construction costs, which helps the valuer and bank understand the project more clearly.
Yes, site visits allow a QS to verify completed work, assess progress claims, identify risks, and ensure the project aligns with the contract and budget. Regular site inspections improve accuracy, reduce disputes, and provide clients with independent oversight throughout the build.
Communication and reporting — related to our QS services
Good communication helps avoid mistakes, delays, and disputes.
Common reports include cost reports, progress reports, and programme updates.
Updates are usually provided weekly or monthly depending on project size.
Yes. A QS can provide cost reports and progress claim reviews.
Poor communication can lead to delays, disputes, and cost overruns.
Cost control — related to our QS services
Cost control is the process of monitoring spending and keeping the project within budget.
Costs increase due to variations, delays, material changes, or unexpected site conditions.
Clear drawings, early planning, and regular cost checks help avoid overruns.
Yes. A QS tracks costs, reviews claims, and checks variation pricing.
A cost report shows the current project cost, committed costs, and forecast final cost.
General project management — related to our QS services
Project management is the process of planning, coordinating, and controlling a construction project from start to finish.
Good project management helps keep the project on time, on budget, and within scope.
A project may be managed by a project manager, builder, architect, or quantity surveyor depending on the structure of the job.
A project manager oversees communication, scheduling, cost control, and quality.
Yes. Even small projects benefit from clear planning and oversight.
Quality and compliance — related to our QS services
Quality control ensures that work meets the required standards and specifications.
Quality may be checked by the builder, project manager, architect, engineer, or QS.
Compliance ensures the building meets legal and safety requirements.
Yes. Poor quality work can lead to rework, delays, and extra cost.
A QS can review work completed and assess the cost impact of defects or rework.
Scheduling and timelines — related to our QS services
A construction schedule is a timeline that shows when each stage of the project will be completed.
Schedules change due to weather, material delays, design changes, or contractor availability.
Clear planning, early decisions, and regular communication help keep the project on track.
Critical path is the sequence of tasks that determines the minimum time needed to complete the project.
A QS can help identify cost related schedule risks and review progress claims.
Absolutely. Renovations and extensions often carry more financial risk than new builds because of unknown conditions, structural changes, and design complexity. A QS provides accurate cost planning, variation control, and financial oversight to ensure the project stays on budget and surprises are minimised.
Finishes and selections — related to our QS services
PC sums are allowances for items like fixtures and finishes that are not fully selected.
Material choices can significantly change cost depending on quality and availability.
Yes, but changes may affect cost and timeline.
Upgrades often involve higher material cost and extra labour.
Yes. A QS can compare costs and help you choose suitable materials.
Foundations and site work — related to our QS services
Foundation cost depends on soil conditions, slope, drainage, and engineering requirements.
Many sites require a geotechnical report to confirm soil strength and foundation design.
Yes. Poor soil may require deeper foundations or additional engineering.
Site preparation includes clearing, levelling, access setup, and service connections.
Foundation design varies due to soil type, building weight, and engineering requirements.
General residential questions — related to our QS services
Residential construction focuses on homes and small dwellings. It usually involves smaller teams, shorter timelines, and more direct involvement from the owner.
A quantity surveyor is helpful for budgeting, cost checks, and progress claims. Many owners use a QS for peace of mind.
A typical home build takes six to twelve months depending on design, weather, and contractor availability.
Residential projects usually need architectural drawings, structural drawings, and consent documents.
Living on site is possible for some renovations but may slow progress and increase disruption.
New builds — related to our QS services
The first step is preparing concept drawings and confirming the project budget.
Yes. Most new homes require building consent from the local council.
Choose a builder with experience, clear communication, and strong references.
Yes. A QS can prepare cost estimates and check builder pricing.
Cost is affected by size, materials, site conditions, and design complexity.
Renovations and extensions — related to our QS services
Renovations can be more complex due to hidden conditions and the need to work around existing structures.
Most extensions require building consent, especially if they change structure or layout.
A QS can provide a detailed estimate, but unknown conditions may still affect final cost.
Clear drawings, early planning, and a detailed estimate help reduce cost overruns.
You may be able to stay, but it depends on safety, access, and the type of work.
A variation is any change to the original scope of work, materials, design, or specifications after the contract is signed. Variations can increase or decrease the project cost. A QS reviews variation pricing to ensure it is reasonable, accurately measured, and consistent with market rates. Proper variation management prevents disputes and keeps the project financially controlled.
Bank and lender requirements — related to our QS services
Banks may require approval for variations that increase the total project cost. They may request an updated QS report.
Yes. If variations increase the project cost, the bank may require additional equity or may not fund the full increase.
Banks release funds for variation work once the variation is approved and the QS or valuer confirms progress.
Not always. Small variations may not require a QS report, but larger cost changes often do.
Yes. If the bank needs updated information, variations can delay drawdowns until documentation is complete.
Disputes and resolution — related to our QS services
Variation disputes often arise from unclear scope, missing documentation, or disagreement about pricing or timing.
Clear documentation, written approvals, and early communication help prevent disputes.
Yes. A QS can provide an independent assessment of the variation cost and scope.
You can request a breakdown, compare it with contract rates, or ask a QS to review the pricing.
Yes. Disputes can delay work if agreement is not reached, especially when the variation affects critical tasks.
Managing changes — related to our QS services
You can reduce variations by finalising design decisions early, completing detailed drawings, and confirming material selections before construction begins.
A change request is a formal document that records a proposed change to the project scope, cost, or timeline.
Changes are usually approved by the owner or project manager. Approval should be in writing to avoid confusion.
You may be able to cancel a variation if work has not started, but cancellation may involve costs for materials or planning already completed.
Yes. Variations should be recorded as formal contract amendments so the project documentation stays accurate.
Pricing variations — related to our QS services
Variations are priced using contract rates where possible. If no rate exists, the builder may provide a breakdown of labour, materials, and margins.
Yes. You can request a clear breakdown so you understand how the variation cost has been calculated.
Variation prices may seem high because they can disrupt scheduling, require extra labour, or involve small quantities that cost more to supply.
Yes. A quantity surveyor can review the variation and confirm whether the pricing is fair and reasonable.
Yes. Agreeing pricing before work starts helps avoid disputes and ensures both parties understand the cost.
Variation basics — related to our QS services
A variation is a change to the original building contract. It may involve extra work, reduced work, or changes to materials or design.
Variations occur when the owner changes the design, when site conditions differ from expectations, or when additional work is required.
Not all variations increase cost. Some variations reduce work or replace items with lower cost alternatives.
Yes. Variations should be approved in writing before work begins to avoid disputes about cost or scope.
Yes. Variations can affect scheduling, subcontractor availability, and material lead times, which may delay the project.
A Quantity Surveyor (QS) is a construction cost expert responsible for managing the financial and contractual side of building projects. Their core role is to ensure that a project is priced accurately, delivered within budget, and financially controlled from start to finish.
A QS works closely with homeowners, builders, architects, engineers, and banks to provide independent, professional cost advice. This includes measuring plans, preparing detailed estimates, forecasting costs, assessing variations, managing progress claims, and ensuring that everyone involved understands the financial implications of design decisions.
In practical terms, a QS helps you avoid budget blowouts, understand where your money is being spent, and maintain full visibility over the financial health of your project. Whether it’s a new build, renovation, extension, or commercial fit‑out, a QS brings structure, clarity, and accuracy to the entire construction process.
