Quantity surveyors prepare cost estimates, bills of quantities and tender documents, then administer the contract once a project starts on site. They work for specialist cost consultancies, building and civil contractors, developers and government agencies, and they measure completed work against the contract as a build progresses. A construction manager runs the programme and the site, while a quantity surveyor's focus stays on the money and the contract.
How much do quantity surveyors earn?
The median full-time salary for a quantity surveyor is $115,300 per annum, before tax, up $24,000 since 2018.
Pay depends heavily on the sector and the size of the projects, with contractors and major infrastructure work generally paying more than small consultancies and government sitting somewhere in between. Chartership through RICS or full AIQS membership usually lifts what you can ask for, and remote or resources projects pay a premium to attract people. Experience on large civil or defence projects moves the figure further than years of service on its own.
What does a quantity surveyor do day to day?
The list below is what fills most weeks; the exact mix shifts with seniority and whatever stage the current work is at.
- Pricing a bill of quantities line by line before a project breaks ground
- Measuring completed work on site so a contractor can be paid for it
- Chasing variation claims and testing each one against the contract
- Comparing subcontractor tenders and recommending who should get the work
- Reporting the current cost position to a client who wants more certainty than a build usually gives

Is the job growing?
About 3,500 people work as quantity surveyors in Australia, and employment is projected to grow 21% over the decade to 2035. That's very strong growth. Few roles in Australia are expanding this fast, and it points to solid demand for years to come.
How do you become a quantity surveyor?
Here's the path most quantity surveyors take, step by step.
- 1Complete an accredited bachelor degree
A three or four year degree in quantity surveying, construction management or property economics gives you the technical base in measurement, estimating and contract law. AIQS accredits the quantity surveying courses that lead most directly into the profession, and accredited degrees include a period of industry placement.
- 2Work while you study
Many students take a cadetship or part-time role with a QS consultancy or contractor, often two or three days a week alongside study. The experience counts toward the practical requirement for professional membership, and it is where a large share of graduates find their first job.
- 3Come across from a related role
Construction estimators, contract administrators and engineers already hold much of the technical ground. A postgraduate qualification in quantity surveying, usually one to two years, is a shorter path than a second undergraduate degree and is widely accepted by employers.
- 4Gain the supervised experience for AIQS or RICS
Full AIQS membership and RICS chartership each require a period of supervised professional experience plus an assessment. Neither is mandatory to work as a quantity surveyor in Australia, but chartership is often asked for on larger projects and by international clients.
Ready to apply as a quantity surveyor?
Whether you're working toward becoming a quantity surveyor or already are one and want a hand with the next step (sharpening your resume for ATS screening, tightening your cover letter, or knowing what you'll actually be asked at interview), here are examples grounded in this specific role, not generic templates.

What's it like being a quantity surveyor?
The work runs on deadlines set by tender closings and monthly reporting cycles, so quiet analytical stretches give way to weeks where several projects need a number at once. Quantity surveyors spend much of the day with drawings, spreadsheets and contract documents, and the rest of it on the phone or in meetings with contractors, designers and clients. It tends to suit people who want to be the one who knows the real cost, and who can hold a position when a contractor disagrees with it.
What people like
- Your numbers decide what gets built. A cost plan often settles whether a design proceeds as drawn or gets cut back, so quantity surveyors are consulted early and their advice shapes the finished building.
- The skills travel. Cost planning and contract administration follow the same methods across building, civil and resources projects, and qualifications such as RICS are recognised overseas.
- Results are measurable. A valuation or a final account either reconciles or it does not, which makes progress easier to see than in roles where success is harder to pin down.
- You end up with projects you can point at. Most quantity surveyors accumulate a list of schools, roads, hospitals or towers they costed, and can walk past them years later.
What people find hard
- Deadlines cluster. Monthly valuations and cost reports for several projects often fall in the same week, and the dates are set by contracts rather than by how much else is on your desk.
- Variation disputes. Deciding what a contractor is owed for a change puts you between the contractor and the client, and the argument can run for months before it settles.
- Detail-heavy days. Measuring and checking quantities line by line is slow work, and an item missed at tender stage becomes expensive to correct later.
- Tender periods. When a tender closes, the window to price it is short, so late nights are common in the fortnight before submission.

Will AI replace quantity surveyors?
Quantity surveying sits in the middle of the range, with the measurement and estimating end of the job automating quickly and the contract side largely untouched. BIM platforms, takeoff software and historical cost databases change how fast a figure can be produced, not who has to defend it when a contractor disputes the number.
Share of typical working time by exposure level
- Negotiating variations and claimsSettling what a change is worth means reading the contract and arguing the point with a contractor over weeks or months, and that conversation has not moved to software.35%low
- Monthly valuations and cost reportsContract systems assemble the report and the arithmetic, but confirming that a contractor's claim matches the work actually completed on site remains a person's job.30%moderate

Common questions about becoming a quantity surveyor
Straight answers to the questions people ask most.
How much does a quantity surveyor earn?
Quantity surveyors earn a median of $115,300 per year before tax. That figure covers full-time workers across consultancies, contractors and government, so what you are offered depends on your sector, the size of the projects you have worked on and whether you hold chartership.
How do you become a quantity surveyor?
The usual route is an AIQS-accredited bachelor degree, with a cadetship or part-time role at a consultancy alongside it so you build site and contract experience before you graduate. People coming from estimating or engineering can take a postgraduate qualification instead of a second degree, then complete the supervised experience for professional membership.
Are quantity surveyors in demand in Australia?
Quantity surveyors are currently in shortage nationally, and employment is projected to grow 21% over the decade to 2035. Demand tracks building and infrastructure activity closely, so the pipeline of major projects matters more to your prospects than any single year's figures.
Will AI replace quantity surveyors?
Much of the measuring and first-pass estimating is being automated, especially where a project is modelled in BIM and quantities can be pulled straight from the model. Contract interpretation, negotiation and the judgement about what a cost figure actually means stay with the surveyor, so the job is changing shape rather than disappearing.
What can a quantity surveyor move into?
Construction management is a common move, where cost planning and budget control transfer and pay is $79,800 more than in quantity surveying, though the role needs further study in programme and site management. Procurement management suits those who enjoy the negotiating side, and many experienced quantity surveyors eventually move into partnership or start their own consultancy, which is often where earnings grow.
What hours do quantity surveyors work?
Full-time quantity surveyors average 43 hours a week, and 87% work full time. The load follows tender closings and monthly reporting cycles rather than an even daily pace, so some weeks run noticeably longer than others.
