What is a detail and contour survey in Australia?

A detail and contour survey is a type of drawing used to identify and locate all the physical features on a piece of land. This includes both natural and man-made elements.
Natural features may include vegetation, rocks, trees, stumps, and other landscape elements.
Man-made structures include buildings, walls, driveways, fences, utilities, and other constructed features.

This type of survey is a standard requirement throughout Australia, especially in New South Wales (NSW), and is usually required before any new construction, renovation, or subdivision project begins.

Steps to complete a detail and contour survey project

Step 1: Review the input data provided by the client

Before starting the project, we need to check whether the data provided by the client is complete. We also need to understand the client’s requirements, identify the site location, and clarify the intended purpose of the survey.

Step 2: Import survey data into Civil 3D.

After the data has been imported, it is important to check that the correct coordinate system is being used. This includes verifying:

The horizontal datum (e.g., GDA2020, MGA Zone 56) matches the project requirements.
The vertical datum (e.g., AHD) is correctly applied to all elevation data.
The units are consistent throughout the dataset.
The base point or benchmark used for positioning is correct and aligns with the project’s control points.

Step 3: Data processing and drafting

Use the point descriptions, site photos, and field notes to accurately complete the linework. Apply survey codes, layers, and symbology in accordance with client or council standards, and create a TIN surface model and contour lines.
