Solutions utilising the AS 5488.1:2019 Australian Standard
The 4 AS 5488.1:2019 Quality Standards
Quality Level A
Information is used to indicate a utility’s precise position in three dimensions and confirm the utility’s attributes such as size, condition and possible material. Provides a reduced project risk for our customers due to the detail and accuracy of the information and is highly valuable for projects reaching the construction phase.
Services that can be utilised
Quality Level B
Utilises existing documentation, site survey and also includes information that indicates the existence and location of subsurface utilities in three dimensions. When this information is compiled using electronic detection it is only an indication of the existence of the utility and does not validate its location or attributes.
This level can most appropriately be utilised as the project develops beyond the initial planning level but before the project reaches the construction phase.
Quality Level C
Utilises existing documentation and also includes a feature or site survey of visible utility assets. It does not however, indicate the location of the subsurface utility with respect to the surface feature
This level is also most appropriately used at the initial project planning level.
Quality Level D
Utilises existing documentation to establish the potential presence of subsurface utilities but does not include any field verification or direct measurement.
This level can be most appropriate at an initial project planning level.
