FAQ
Get answers to your frequently asked questions about construction, cost estimation, quantity surveying, tendering, and much more.
Can I use your estimate to check a builder’s price?
Yes. Developers and homeowners regularly engage us to provide an independent cost assessment against a builder’s quote. We measure the project from the drawings, apply current Melbourne market rates and give you a line-by-line comparison so you can see where the builder’s price is fair and where there’s room to negotiate.
This is particularly useful when you’ve received a single builder quote with no competitive tension.

What if I have questions after I receive the estimate?
We don’t hand over a spreadsheet and disappear. Every estimate includes a walkthrough where we talk you through the numbers, flag where risk sits and explain our assumptions.
If a subcontractor price comes back different from our allowance, call us we’ll help you reconcile it. Our job isn’t finished when the spreadsheet lands in your inbox. It’s finished when you’re confident enough to submit your tender.

What sets Pekaj Group’s estimating apart?
Contractor-side experience. Before starting Pekaj Group, Coba ran the estimating department at a tier-1 Melbourne subcontractor where the team helped secure over $200 million in work across major projects including West Side Place, The Parkhouse, Mason Square and Sky One.
That means we price the way builders and subcontractors actually buy and build not from a textbook or a cost guide. We use CostX, we measure to ANZSMM 2022 (if required) and we deliver in a format that fits straight into your workflow.
Resources
How accurate are your estimates?
A preliminary estimate at tender stage targets 80-85% accuracy. Some details between you and your client may still be in play. A detailed estimate with full documentation should sit at 90–95% acurracy.
We recommend applying a 3–5% contingency on top to cover unknown site conditions, minor variances and price movement between estimate and construction.
We always tell you where the risk sits in a number rather than burying it in a lump sum.
Resources
Why should I outsource estimating instead of doing it myself?
Time. Every day you spend pricing a job is a day you’re not on site, not running your current projects and not chasing new work.
A full-time estimator costs $80k–$120k a year in salary plus software, overheads and super. Most small to medium builders doing fewer than 50 estimates a year are better off outsourcing. You pay per project, only when you need it and you get someone who prices across the Melbourne market every week not just your own jobs.
Resources
How long does an estimate take and can you meet my tender deadline?
Standard turnaround is 5 working days from acceptance of fee proposal. Smaller projects can be faster.
If your tender closes inside that window, tell us upfront we’ll confirm within 24 hours whether we can meet the deadline. We factor our workload around tender dates because that’s the reality of the market.
We won’t take on a job we can’t deliver on time.
Resources
Do you do trade-specific take-offs?
Yes. We prepare material take-offs and quantity schedules for individual trades including concrete and reinforcement, structural steel, timber framing, tiling, waterproofing, painting, joinery, glazing, cladding, demolition, earthworks and more.
If you’re a subcontractor who needs quantities measured from drawings so you can price your scope accurately, we can help. You get a detailed take-off in Excel with marked-up drawings showing exactly what’s been measured and how.
If your trade isn’t listed, get in touch if we can measure it from the drawings, we can take it off for you.
Resources
How does your estimate help me win tenders?
A competitive tender comes down to accurate pricing. If your numbers are too high, you lose the job. Too low, you win it and lose money.
Our estimates are built from contractor-side experience we know what numbers win work because we’ve sat on that side of the table. We price the way builders actually buy and build, using current Melbourne subcontractor and supplier rates, not published cost guides. You get a number you can stand behind with confidence.
Resources
Can you estimate from early-stage or incomplete drawings?
Yes. We regularly work from DA drawings, concept sketches, or partially documented designs where full working drawings aren’t available yet.
We make reasonable assumptions based on experience, clearly state what’s included and excluded and flag where cost risk sits because the design isn’t resolved. This gives developers a budget range to test feasibility and gives architects cost confidence to share with their clients before committing to full documentation.
Resources
What do I actually receive when the estimate is finished?
An Excel spreadsheet exported from CostX with a full trade-by-trade or elemental breakdown including quantities, rates and totals. Plus, a complete set of marked-up drawings showing everything that’s been measured if required.
The spreadsheet is fully editable so you can drop in your own subcontractor pricing, adjust allowances and present it to your client in whatever format suits your business. If you have your own subcontractor rates or supplier pricing, we can apply those instead of market rates just send them across with the drawings.
We don’t hand over a locked PDF and walk away.
Resources
What’s the difference between a BOQ and a trade breakdown?
A BOQ (Bill of Quantities) is measured to ANZSMM 2022 and structured by element. It’s the formal documentation standard used for competitive tendering and contract administration. This format is predominantly used by developers and architects.
A trade breakdown groups the same quantities by trade in construction sequence such as demolition, earthworks, concrete, framing and so on. The trade breakdown is our most requested format because it maps directly to how builders engage subcontractors and manage costs on site.
We produce both from the same CostX model, exported as an editable Excel spreadsheet, with marked-up drawings showing exactly what’s been measured.

How much does it cost to build in Melbourne right now?
It depends on what you're building. Here's a guide to current Melbourne construction costs by project type for 2026:
These rates cover construction costs only. They don't include land, professional fees (architect, engineer, surveyor), council contributions, authority charges, or loose furniture and equipment. Site costs demolition, excavation, retention, rock removal sit outside these ranges and can add $30,000–$150,000+ depending on conditions.
Rates also move. Melbourne construction costs have been escalating at 3–5% per year since 2022, driven primarily by labour shortages and material price volatility. A rate that was accurate six months ago may already be light.
If you want a number you can actually rely on, send us your drawings and we'll prepare a project-specific estimate. For a detailed breakdown of current Melbourne trade rates, see our 2025 Trade Rates Guide.
Resources
What does a quantity surveyor actually do for my project?
We manage the money side of your build from start to finish. That includes cost planning before you start, tracking costs during construction, assessing progress claims, managing variations, and preparing the final account at the end.
Think of it as having someone independently watching every dollar so nothing slips through — whether you’re a builder managing subcontractors or a developer keeping lenders informed.
When should I engage a QS?
As early as possible. Ideally at design development stage, before you go to tender. The earlier we’re involved, the more we can influence cost outcomes flagging risks, identifying savings and making sure the design aligns with your budget.
If you come to us after contracts are signed, we can still help with cost control and claims, but the biggest value comes from getting involved early.
How much does a QS cost in Melbourne?
Fees depend on the project type, complexity and which services you need. Here’s a guide to typical QS fee ranges for Melbourne projects:
These are indicative. Every project is different and the final fee reflects the level of documentation available, the number of trades involved and the duration of our engagement.
We provide a fixed-fee proposal for every project before starting no surprises.
What’s the difference between a QS and an estimator?
An estimator tells you what a project will cost before construction starts. A QS manages that cost through to completion tracking expenditure, assessing claims, handling variations and closing out the final account.
We do both at Pekaj Group. Most builders need estimating at tender stage and QS support once the project is awarded.
Do I need a QS if I already have an estimator?
Possibly. If your estimator prices the job and moves on, nobody is watching costs during construction. That’s where budget blowouts happen through unmanaged variations, unchecked progress claims and scope creep.
A QS picks up where the estimator finishes and makes sure the project closes out on budget. If you’re running multiple projects at once, this is where the value really shows.
What do you need from me to get started?
For cost planning or a BOQ, we need architectural drawings, engineering documentation, any specifications or schedules and the project brief. For contract administration, we’ll also need the executed contract and programme.
Send whatever you have we’ll review it and tell you if anything is missing before we quote.
What types of projects do you take on?
Residential through to commercial. That includes single and double-storey homes, townhouse developments, low-rise apartments with basements, renovations/extensions, shop fit-outs, industrial (factories) and modular builds.
If your project falls outside this range, get in touch anyway we’ll tell you straight if we can help or if you need a larger practice.
How do you handle variations during construction?
We assess every variation against the contract and original scope. That means checking whether the variation is valid, whether the pricing is fair and whether it was instructed properly.
We don’t just rubber-stamp claims we interrogate them. You get an independent view on what’s reasonable before you approve anything.
Can you help with progress claims and payments?
Yes. We review contractor progress claims against actual work completed on site, check retention calculations, verify that claimed amounts align with the contract and provide recommendations on what to certify.
This protects both builders managing subcontractor payments and developers managing head contractor claims.
What qualifications does your team hold?
Pekaj Group is led by Coba Pekaj, MAIQS CQS, with over 23 years of experience in estimating and quantity surveying across the Melbourne market. We’re members of the Australian Institute of Quantity Surveyors.
CQS (Certified Quantity Surveyor) is the highest professional designation in the field held by a limited number of practitioners nationally.
How do you work with my existing team?
We slot in alongside your project manager, site supervisor and admin. We don’t take over, we handle the cost management, claims and commercial side so your team can focus on delivery.
Most of our builder clients don’t have a dedicated QS on staff, which is exactly why they engage us. You get the expertise without the overhead of a full-time hire.
Can you help me track costs during construction?
Yes. We provide cost-to-complete reporting that shows you where you stand against budget at any point during the build. That includes committed costs, forecast final cost and early warnings on trades that are trending over.
This is particularly valuable on townhouse developments and multi-unit projects where small overruns across trades compound quickly.
How do you work with architects?
We provide independent cost advice at each design stage so your clients have budget confidence before you go to tender. That means you’re not in the uncomfortable position of presenting a design that comes back over budget when builders price it.
We work collaboratively our job is to help you deliver your design intent within the client’s budget, not to cut scope for the sake of it. We produce elemental cost plans from concept through to pre-tender documentation so there are no surprises at pricing stage.
Do you provide reports for lenders and banks?
Yes. We prepare initial feasibility reports, cost-to-complete assessments and progress claim reviews in formats that major Australian lenders accept. If your bank or financier has a specific reporting template, we'll work to their requirements.
If your broker has asked for a QS report without specifying which one, the simplest rule is: single dwelling construction loan means a QS Bank Report. Development finance means an Initial Financier's Report. Confirm with the lender before engaging.
Our assessments are completed remotely via desktop review of project documentation. If a site inspection is required, we engage trusted third-party professionals to attend on our behalf.
We understand that drawdown approvals depend on the quality and clarity of the QS documentation behind them.
I only have town planning drawings. Can you prepare a report for the bank?
Can I use the same QS report with a different lender?
No. A report is addressed to a specific financier and carries professional indemnity reliance for that lender only. Changing lenders requires a supplementary report.
What is cost-to-complete and why does the bank use it?
Cost-to-complete is how lenders control drawdowns during construction. Instead of paying the builder for work done, the lender checks whether the remaining budget is enough to finish the project. This protects everyone from running out of money before completion.
This can mean the QS recommends a lower drawdown than the builder claims. It is not a reflection on the builder's work quality. It is the lender's risk management methodology.
Does the QS need to be on the bank's approved panel?
Most major banks and non-bank lenders maintain approved QS panels. If the QS is not on the panel, the report may be rejected. Before engaging any QS for a bank-facing report, confirm with your broker or lender that the firm will be accepted. Not all lenders publish their panel lists, so this step is essential.
If you are unsure whether your QS will be accepted, ask the lender directly before work commences. A report from a non-panel QS may not be accepted regardless of quality.
