Course Description
Having accurate knowledge of subsurface/ underground/ buried utilities (pipes/ cables/ drains etc.) is critical for any infrastructure project. The successful detection and mapping of buried utilities involves the combination of several techniques, the results of which are synthesized down to a single interpreted plot. The techniques and methodologies used will primarily depend upon the required outcome for the survey, the site conditions and the type of pipes or cables being targeted.
Subsurface Utility Engineering (SUE) is an upcoming field dealing with procedure and standards for detection and mapping of underground utilities.
The course comprehensively covers all the aspects related to conducting a successful underground utility detection and mapping project.
The program will benefit an individual or organization by helping in reducing risks and costs involved while meeting an existing utility unexpectedly during construction. The program will also help organizations plan towards creating database of existing utilities in their area (refineries/ plants/ urban/ public areas/ factories) for future reference/ expansion plans/ repair & rehabilitation. Similarly, the utility owners could create the composite as built asset map on a real location basis for their administration and management.
There is an urgent need for capacity building in the field of SUE, and program will also help participants to pursue career in this field. Smart utility maps are prerequisite for smart cities, making this workshop very important for smart city planners.
