What is Quantity Surveying? 

Contrary to the impression that Quantity Surveyors are the people who do land surveys using transit, Quantity Surveyors are Construction Cost Consultants. But take note, it is not just all about estimating. In fact, this discipline involves a wide expertise, being a Quantity Surveyor also means performing the following roles in construction projects:

  • Cost Manager
  • Construction Economist
  • Estimator
  • Accountant
  • Contract Administrator
