Contour & Feature Survey

Contour and Feature Survey
What is a Contour and Feature Survey?

A Contour and Feature Survey Plan is a graphical representation of your property. It is used to display the height of retaining walls, fence lines, existing services e.g. water meter, and the overall finished height of existing buildings, on natural ground level, on your property. Reasons for needing a contour survey include but are not limited to :

  • New Building Design

  • Survey for Architect

  • New Swimming Pool

  • Retaining Wall Disputes

  • Suspected Land Level Change

  • New Retaining Wall

  • New Verandah

  • House Extension

  • New Carport

  • New Driveway

  • Surveying Neighbouring Buildings

  • Tree Shadowing Diagrams

  • New Balcony

  • New Boundary Wall

What on earth is AHD?

Australian Height Datum (AHD): "means a level of datum, derived from mean sea level observations along the Australian coastline, used uniformly throughout Australia as a base reference for 'derived' datum levels.


Basically an AHD required survey is when a surveyor connects the heights of the survey to local survey control or sewer information that has existing AHD height values assigned to it. This height value has been calculated relative to the Australian sea level at the coastline which if thought about simply would have a value of (0).


What this means on your plan is that if you see the elevations (heights) on your survey plan and they are on average 50.00 or 50.25 this means your property would be approx. 50m above sea level.
