A sample answer to question 1

Why do you want to become a quantity surveyor rather than another role in construction?

I want to be a quantity surveyor because I enjoy the combination of numbers, buildings and problem solving. A QS is responsible for managing costs from early budgets to final account, so you influence whether a project is financially successful. I like that the job is varied, with office work such as measuring, valuations and reports, plus site visits to see progress and talk to teams. I have also looked at the alternatives, such as site management and project management, and I realised I am more interested in the commercial side, and in contracts like JCT and NEC, rather than running day-to-day site operations. The RICS pathway also appeals to me, because chartered status is respected globally and gives a clear route to progress through the APC. During my studies, I enjoyed cost planning modules and a placement where I helped check a valuation, and I realised I like the detail and the responsibility. I want to learn from experienced QSs and build my skills steadily.

Common mistake to avoid: Saying it is just a well-paid job; Not knowing what a QS does
