About Cardno AUS

Cardno AUS is a renowned industry leader for the mapping and management of existing underground utilities and excavating within high risk and sensitive environments.

Formerly known as Australian Underground Services, Cardno AUS has been delivering subsurface utility engineering (SUE) services to private and government clients within the construction, environmental, geotechnical, mining, energy, and defense sectors since 1995.

In early 2012, Cardno AUS merged with Locom Australia, a Queensland-based organization specializing in utility management strategies and asset relocation, to become a SUE leader across Australia.

Cardno AUS has three offices in three states employing 40 professional, technical and support personnel. Our experienced and accredited team of surveyors, engineers, professional utility coordinators, data depiction analysts and project managers is committed to delivering an efficient and effective service for quality environmental, civil, building and development projects.


Subsurface utility engineering is a process combining civil engineering, geophysics, survey and computer-aided design and drafting (CADD)/geographical information systems (GIS). Information about the location and condition of subsurface utilities is collated and assessed to reduce the occurrence of interference and conflict with valuable infrastructure.

Our integrated SUE services include:

  • preliminary/desktop research to obtain existing utility information
  • utility detection through the application of surface geophysical methods to identify the approximate position of subsurface utilities
  • ground penetrating radar to identify various subsurface features and assess structures
  • non-destructive digging (vacuum excavation) to expose subsurface utilities at critical points to obtain their exact coordinates/location and attributes
  • survey and depiction of subsurface utility data with in-house capabilities to output in various formats such as AutoCAD, 12D and/or GIS
  • professional utility coordination throughout a project lifecycle.

Subsurface utility engineering is applied throughout the lifecycle of a project from concept phase to design, through to construction and finalisation. Project and utility owners, designers, engineers and contractors can significantly benefit from adopting a SUE process during the life cycle of a project to avoid:
  • unexpected costly utility conflicts
  • project delays
  • utility damage
  • community issues
  • contractor claims.


Our clients include a broad range of private and government organizations including, Vic Roads, Department Transport and Main Roads, BMD, Roads and Maritime Services, BP, Exxon Mobil, Thiess, Lend Lease, Leightons, John Holland and Melbourne Water.
