Continuing from last week’s article on ‘Underground Services – Field Location Methods’ (Part 1 of our 3-Part series), we summarise the Australian Standards for the recording of underground services and their various classifications.
The level of detail and accuracy you will need is dependent on what stage of the development you are at, balanced by the need to provide sufficient data to your design team.
Classification of Subsurface Utility Information (SUI)
Australian standards have been developed to provide a consistent framework for the classification of information concerning underground services. They are separated into 2 parts:
- Part 1: AS 5488.1:2019: Primarily deals with location of the assets
- Part 2: AS 5488.2:2019: Utility model creation and data naming conventions and survey engagement
Standard colours (see below), line types and quality levels are some of the national standards you may see represented on our survey plans. These help in minimising confusion and misinterpretation by the end users of the data.
