AS 5488.1:2019 PDF
This Standard provides a framework for the classification of subsurface utility location and attributes information in terms of specified quality levels for the management of subsurface utilities.
This Standard focuses on the classification of Subsurface Utility Information (SUI). AS 5488.2 provides guidance on the management of subsurface utilities, as referred to by Subsurface Utility Engineering (SUE).
This Standard also provides guidance on issues such as how subsurface utility information may be obtained (refer to AS 5488.2), and how that information should be conveyed to the information users.
This Standard also recommends, through the adoption of Quality Level A, the absolute positioning of subsurface utilities in three dimensions, as an improvement upon the current widely adopted method of relative positioning.
