The main function of a quantity surveyor is to manage the construction of a building, covering both technical and legal aspects. The following are the main functions carried out by quantity surveyors on a construction site:

  • Direction and execution of the construction: the quantity surveyor is responsible for directing and executing the construction, supervising the quality of the materials used.
  • Guarantee of suitable materials: the quantity surveyor ensures that the materials used in the construction are those specified in the project, including the acceptance of the tests and trials carried out.
  • Ensuring compliance with the project and budget: the quantity surveyor ensures that the execution of the project complies with the design and the established budget. This involves checking the layout, supervising the correct execution and layout of the elements, as well as controlling the budgetary items of the work.
  • Contingency resolution: the quantity surveyor is in charge of resolving contingencies that may arise during the development of the work and keeping control of them.

Optional management of the work

The project management consists of the architect as project manager (macro-control), who carries out an overall control of the project, and the execution management, carried out by the quantity surveyor, which involves a detailed control of the work carried out (micro-control). The quantity surveyor directs, supervises and ensures that each element fulfills its function and complies with the project and the corresponding regulations.
