A quantity surveyor manages all costs relating to the build, from the initial calculations to the final figures. As part of this, quantity surveyors seek to minimise costs and enhance value for money, while still achieving the high standards and quality. It's also important that they have an understanding of statutory building regulations. A quantity surveyor may work in an office or on site and are involved in a project from the start, preparing estimates and costs of the work. During the build, they also have to keep track of any changes to the site that may affect costs and create reports to show profitability.
