Subject Overview

Surveying and Levelling develops the principles and professional skills required to measure, represent and set out the built environment. It covers conventional field methods, levelling, control surveys, construction layout, earthwork calculations, modern geospatial technologies, data management, quality assurance and emerging digital practices.

Learning Goal

Students will be able to plan, execute, analyse and document surveying and levelling work; select appropriate instruments and methods; assess errors and uncertainty; produce reliable spatial information; support construction decisions; and practise safely, ethically and in accordance with professional standards.
