A Contour Survey (also commonly referred to as a Detail Survey or Topographic Survey) shows the features and structures within and adjacent to a parcel of land. The amount of information shown varies depending on individual requirements but can include; the location of buildings, windows, driveways, walls, trees and natural surface features such as watercourses, embankments, rock outcrops and contours.

A Contour Survey is required for a variety of reasons. Commonly it accompanies a Development Application (DA) to Council or acts as a provision to an Architect or Engineer for building and infrastructure design. It may also be required for flood studies, detailed landscape design and structural engineering.

As every land parcel is unique, so are our surveys. We tailor each survey to your specific needs and provide easy to read plans and well-structured CAD models to make the process as easy as possible.

The Contour Survey Process
