Quantity Surveyor
A quantity surveyor manages the money and contracts on construction projects - working out what a building or infrastructure scheme should cost, keeping track of what it actually costs as work progresses, and sorting out payments and disputes between the parties involved. They work either for a client or consultancy (advising the organisation paying for the work, often called "PQS" or client-side) or for a contractor (the company actually building it, where the role is often called a commercial manager or contractor's QS). Typical projects range from housing and schools to hospitals, rail, water and energy infrastructure.
Approximate graduate salary
Graduate starting salaries are typically around GBP 25,000-33,000, though this varies widely by employer type and region - London and major infrastructure programmes sit at the higher end, and smaller regional firms lower. Pay commonly rises noticeably on achieving chartered status.
What you'd actually do
- Measuring quantities from drawings and models - working out how much concrete, brickwork, cabling or groundworks a design requires - increasingly using digital take-off software and 3D models rather than paper drawings and a scale rule
- Building and updating cost estimates and budgets, then explaining to a project manager or client why a figure has moved since last month
- Preparing or reviewing tender documents and bills of quantities (an itemised list of the work and materials that contractors price against), then comparing the bids that come back
- Doing monthly valuations - visiting site or reviewing progress records to assess how much work has genuinely been completed, so the right amount gets paid to the contractor or subcontractor
- Pricing and negotiating variations (changes to the agreed scope of work) and assessing claims for extra time or money, which involves reading the contract clause by clause
- Sitting in commercial and progress meetings with site managers, designers and clients, and writing up cost reports for whoever is funding the job
- Procuring and managing subcontractor packages if working contractor-side - putting work out to price, agreeing terms, and dealing with the payment applications that come back
How graduates get in
- Structured graduate schemes at construction consultancies, main contractors, housebuilders and infrastructure clients - the most common route, usually recruited in the autumn or spring for a September start, and typically including structured support towards chartership
- Direct entry as an assistant or graduate quantity surveyor, especially with regional contractors, subcontractors and smaller consultancies who recruit as vacancies arise rather than on an annual cycle - very common and often less competitive than the big schemes
- A RICS-accredited undergraduate degree in quantity surveying, commercial management or construction management, which is the most straightforward academic path
- A RICS-accredited conversion Master's (often one year full-time, or part-time while working) for graduates from unrelated degrees - a well-established and genuinely common route, sometimes funded by an employer
- A summer placement or a sandwich year in industry - widely used by employers as a recruitment pipeline, and a placement year often converts directly into a graduate offer
- Degree apprenticeships in quantity surveying - relevant if you are considering routes other than a traditional degree, or if you already work in construction and want to convert experience into a qualification
What employers ask for
- A degree accredited by RICS (the Royal Institution of Chartered Surveyors, the main professional body) is the smoothest path - typically quantity surveying, commercial management or construction management. If your degree is not accredited, employers usually expect you to take an accredited Master's, and many will part-fund it
- Degree subject matters more here than in many graduate careers, but non-cognate graduates are genuinely welcomed - numerate subjects such as maths, economics, engineering, geography and even law transfer well via the conversion route
- A 2:1 is common at large consultancies and contractors, but plenty of employers accept a 2:2 with relevant experience or a strong interview - this varies a lot by employer size
- Commitment to working towards chartered status (MRICS) through the APC - the Assessment of Professional Competence, a structured period of logged experience and a final interview and submission. Some employers instead or additionally support CIOB or RICS-alternative routes
- Any construction exposure helps - a placement, site work, family trade experience, or even labouring - because employers want evidence you understand what a building site is actually like
- A full driving licence is often expected or preferred for site-based roles, particularly outside major cities
Skills that matter
Reading and interpreting construction contracts
Standard forms like JCT and NEC decide who pays when something goes wrong, and a QS is expected to find and apply the relevant clause rather than guess at what feels fair.
Numerical accuracy and comfort with large spreadsheets
A misplaced decimal in a valuation or a duplicated line in a bill of quantities can move real money, and errors are usually caught by someone else in an uncomfortable meeting.
Measurement and drawing literacy
You need to look at a set of drawings or a 3D model and understand what is actually being built before you can price it or check whether it has been built.
Negotiation and holding a position under pressure
Agreeing the value of a variation or a final account means arguing a number with someone whose job is to argue the opposite, sometimes for months.
Clear written record-keeping
Entitlement to extra money often rests on notices being issued on time and correspondence being logged, so sloppy admin quietly loses money.
Commercial judgement about risk
Much of the job is spotting where a price, a programme or a contract term hides a cost that has not been allowed for, and flagging it before it lands.
Where it leads
Graduate or assistant quantity surveyor - working under a senior QS on packages or sections of a project, building the evidence base needed for chartership. Most people spend roughly the first couple of years here.
Achieving MRICS through the APC - commonly around two years or so after graduating for those on a structured scheme with an accredited degree, but timelines vary widely depending on the range of experience you can log and how supportive your employer is. Chartership is the main step change in pay and credibility.
Quantity surveyor, then senior QS - running your own packages or smaller projects end to end, with more client contact and often some responsibility for graduates below you.
Managing or associate level - contractor-side this tends to mean commercial manager and then commercial director, running the commercial function across several projects or a region; consultancy-side it means associate, then director, with growing responsibility for winning work and managing client relationships.
Sideways moves are common and well trodden - into project management, cost consultancy leadership, contract or claims specialism (including dispute resolution and expert witness work), client-side roles at developers, housebuilders or infrastructure owners, or self-employed contract consulting. Some QSs move into property development where the cost knowledge is directly useful.
What people get wrong
“It is a surveying job where you stand outside with a tripod measuring land.”
That is a land or geomatics surveyor - a different profession entirely. A quantity surveyor measures quantities of work and money, and spends far more time with contracts, spreadsheets and meetings than with instruments.
“You spend most of your time on site in a hard hat.”
Most QSs are office-based or hybrid, with site visits for valuations and progress checks. Contractor-side roles are usually more site-heavy than consultancy roles, but even then a lot of the work is desk work.
“It is a pure maths job, so you need to be brilliant at advanced mathematics.”
The arithmetic is mostly straightforward; the difficulty is in judgement, contract interpretation and negotiation. Being persuasive and precise in writing matters at least as much as being quick with numbers.
“The QS is just a bookkeeper who records what things cost.”
The role is commercially adversarial in places - you are often the person deciding what a claim is worth, refusing a payment application, or defending a client's budget against pressure from several directions.
Where this varies
The biggest split is client-side versus contractor-side. Working for a consultancy or client, you advise on budgets, procurement and cost control across several projects, usually from an office with periodic site visits. Working for a contractor or subcontractor, you are protecting your own company's margin on one or two projects, often based in a site cabin, with more procurement of subcontractors and more day-to-day commercial pressure. Contractor roles frequently pay more early on; consultancy roles tend to give broader exposure and a clearer path to chartership. Sector matters too - housebuilding, commercial buildings, rail, water and energy each use different contract forms and have different rhythms. Geography matters for both pay and project type: London and the South East are dominated by commercial and residential development, while large infrastructure programmes are spread across the country and can be a significant draw in regions where they are based.
