Underground utility engineering, surveying and management is an emerging professional discipline in Hong Kong and elsewhere, where the new underground utility networks are getting much complicated and the old ones are aging.It has been four years since our underground utility management and surveying specialism has been launched as one of the three streams in our BSc (Hons) in Geomatics in LSGI, PolyU, as the first such undergraduate degree program in the world.This relatively new scope extends the land surveying discipline from the scope of positioning, mapping and monitoring from above ground objects to underground objects.At present, the demand is no longer only about safety, but also extends to detail 3D underground/subsurface mapping, monitoring and method validation with precise land and underground surveying technologies, as well as customization of this information into unified database using geographical information system (GIS).Our stream strives to provide a total solution that help to solve a range of underground utility problems at different stages and provides training starting from undergraduate level.This paper attempts to answer four fundamental questions via defining our scope of training with six domains: (1) Geo-spatial positioning and mapping, (2) Condition survey, monitoring and diagnosis, (3) Coordinated and integrated system and design for new construction, (4)Trenchless construction, (5) Trenchless maintenance, and (6) Construction, operational, business, and data management.
