Quantity Surveyor Brisbane — Independent Cost Management for Your Build

An estimate tells you what a project should cost on day one. A quantity surveyor in Brisbane makes sure it still costs that on the day you settle the final account.

Matrix Estimating provides independent quantity surveying across Brisbane, the Gold Coast and the Sunshine Coast — cost plans at feasibility stage, bills of quantities for tender, progress claim assessment during construction, and variation review when the scope moves. We work for the party paying the bills, not the party issuing them.

Scope of work

Our Quantity Surveying Services in Brisbane

We can pick up a project at any stage, or run cost management end to end.

  1. Feasibility & Cost Planning

    Before you commit, we test whether the numbers work. Elemental cost plans built from real Brisbane rates tell you what the scheme costs and where the money goes, so you can adjust the design while changes are still cheap.

  2. Bills of Quantities & Tender Documentation

    A measured BOQ puts every tenderer on the same scope, so the prices you get back are genuinely comparable. It removes the guesswork from bid analysis and takes the scope-gap arguments out of the job before they start.

  3. Tender Review & Contractor Selection

    We assess submitted bids line by line against the documentation, flag underpriced items that will come back as variations, and give you a written recommendation you can put in front of a board or a lender.

  4. Progress Claim Assessment

    We check what the contractor has actually built against what they have invoiced, and certify the amount properly payable. You pay for completed work, not for optimism.

  5. Variation & Change Assessment

    When scope moves — and it will — we price the change independently and confirm whether the claim is valid and the rate is fair before it lands in your budget.

  6. Cost Reporting Through Construction

    Regular cost reports showing committed spend, forecast final cost and remaining contingency, so a problem shows up in a report months before it shows up in your bank account.

  7. Final Account Settlement

    We reconcile the whole job at completion — contract sum, variations, provisional sums, prime cost items — and negotiate the closing position so the project ends cleanly.

Common question

Do I Need a Construction Estimator or a Quantity Surveyor?

They overlap, but they answer different questions. Most Brisbane clients need one clearly more than the other.

Construction Estimator

“What will this cost to build?”

  • One-off pricing before you start
  • Quantity take-offs from your drawings
  • Fast turnaround for tender or finance
  • Best for builders, tradies, renovators and owner-builders

Quantity Surveyor — this page

“How do I control cost across the whole job?”

  • Ongoing role from feasibility to final account
  • Cost plans, BOQs, progress claims, variations
  • Independent certification you can give a lender or board
  • Best for developers, owners, architects and contract administrators

Local market

Quantity Surveying Built on QLD Rates and QLD Contract Conditions

South East Queensland is building hard, and that pressure shows up in prices before it shows up in any index. Infrastructure and the 2032 Games pipeline compete for the same trades, plant and materials that residential and commercial builders need, and the effect runs from the CBD out through Logan, Ipswich and the Coast.

The conditions here also drive real cost. Flood overlays along the Brisbane River and its creeks change floor levels, footings and insurance. Wind region ratings step up as you move north along the coast and feed straight into structural and cladding costs. And renovating a raised Queenslander — restumping, building in underneath, working around timber that was never square to begin with — prices nothing like a slab-on-ground job.

Then there’s the contract layer, which is genuinely different in Queensland. The Building Industry Fairness (Security of Payment) Act governs payment claims and, on qualifying projects, requires project trust accounts and retention trust accounts. That changes how money moves through the job and how claims must be handled. We assess claims against the contract and the programme so you respond within time and on solid ground.

Independent numbers. QLD rates. No surprises at final account.

Estimating software icon

Measured Properly

At Matrix Estimating, we use leading estimating software to deliver exceptional accuracy and detail in every cost plan and bill of quantities. We take great pride in our advanced 3D quantity take-offs — an intuitive alternative to traditional 2D methods that provides a clearer picture of your project's scope. Every measured item can be traced back to the drawings, so you can check what has been measured, where it occurs and exactly what is included. That traceability is what makes a progress claim or a variation defensible when someone questions it.

Our deep understanding of the Queensland market means our cost plans reflect what trades are actually charging in Brisbane right now — not a national average.

Cormac was indeed very helpful - providing a detailed construction price range so we knew where to begin by way of commencing our budgeting process. Not many QSs provide such goodwill. Highly recommended

I recently engaged Cormac to assist with estimating a large residential construction project and was genuinely impressed. His work was thorough and detailed — every line item was considered, nothing was glossed over, and the output gave me real confidence going into the quoting stage. He was also generous with his time, happy to walk through his methodology and answer questions without rushing. That kind of transparency is rare and genuinely useful when you're trying to understand the numbers, not just receive them. I'd recommend Cormac without hesitation to anyone needing accurate, professional estimating on significant volumes of construction work.

Cormac’s advice stood out to me for being clear, honest, and refreshingly transparent, exactly what I was looking for as a person in need of his excellent building knowledge. He took the time to help me understand my options with the situation I was in. This level of care and clarity gave me genuine confidence in the decisions I was making. What I appreciated most was Cormac’s willingness to provide me advice quickly. It made what could have been a stressful experience feel smooth, well-managed, and ultimately very reassuring. I would %100 recommend giving him a call!

Cormac from Matrix Estimating has delivered a high-level estimate that demonstrates both depth and breadth of understanding. While preliminary in nature, the estimate appears to comprehensively cover the full scope of works, giving us a strong foundation for early-stage planning and decision-making. Cormac’s extensive construction knowledge is clearly evident in the way he approaches costings—his ability to translate technical detail into practical, well-structured estimates is a real asset. The breakdowns are clear and logical, with a level of detail that instils confidence in the numbers, even at this early stage. Communication has been seamless throughout. Cormac is responsive, approachable, and easy to engage with via one-on-one Teams meetings. He takes the time to explain his rationale and is open to feedback, which makes the process collaborative and efficient. Upon completion of the project, I am looking forward to comparing actuals V estimate. Highly recommended for anyone seeking a knowledgeable, professional, and easy-to-work-with estimator who brings clarity and confidence to the early stages of a project.

I was very pleased with the estimate that Cormac Gray put together for our new build. This will allow me to have confidence in knowing what the final cost of the new house will be and hence arrange finance. Cheers Barry Gilbertson

We highly recommend Matrix Estimating for anyone needing clarity and confidence around building costs. We engaged Matrix Estimating after receiving a builder’s proposal that lacked a clear cost breakdown, leaving us feeling overwhelmed and unable to make a confident decision about proceeding with our build. Cormac completely changed that by delivering a new, detailed, and categorised estimate that brought structure and transparency to the project. He took the time to walk us through the cost breakdown and clearly explained the underlying methodology, including the assumptions and benchmarks used. This enabled us to make informed budget decisions with a solid understanding of where each cost originated. From the outset, Cormac was professional, responsive, and delivered exactly what we needed. His report met our brief perfectly - easy to interpret, methodically structured, and underpinned by industry-standard metrics and evidence-based logic. Thanks to Matrix Estimating, we’re now in a much stronger position to engage with our builder on a definitive, realistic budget. Cormac listened, supported us through the process, and delivered a service that reflects both technical expertise and practical insight.
