How do quantity surveyors work?

Before a construction project starts, a quantity surveyor will study drawings and specifications about a new building normally provided by architects or engineers.

They must also provide accurate labour and work costs.

Quantity surveyors rely on a range of technical measurement tools to come to accurate costs. For example, Building Cost Information Service (BCIS) data to give early cost advice, to budget and benchmark projects and to prepare life cycle cost plans. They will also have a thorough understanding of Building Regulations in order to adhere to them and ensure that the project passes Building Control. During the build they keep a constant check on costs.
