National Utility Contractors Association  NUCA-TAG-R
The Australasian Society for Trenchless Technology (ASTT) allows all ASTT Members to gain access to a new web-based tool for identifying trenchless construction methods that are suitable for a particular set of project attributes (e.g., diameter, length, depth of cover, geological and hydro-geological conditions, allowable pipe materials, etc.).

TAG-R Online is a fully automated web-based decision support system for the selection of underground utility construction methods, primarily with trenchless technology.
Features of TAG-R Online:
Includes a detailed method database of more than 80 technologies capable of installing, replacing and rehabilitating underground utilities
Capable of evaluating sanitary, storm and combined sewers (gravity and force mains), water mains, laterals and manholes using commonly available project data
Provides the user with technically viable construction methods which can address their specific project needs

The online version of TAG-R was developed by the Trenchless Technology Center (TTC) at Louisiana Tech University in Ruston, Louisiana. The Trenchless Assessment Guide (TAG) was originally developed by the TTC for the National Utility Contractors Association (NUCA), a USA based organization as a stand-alone software.
