Underground Utility Positioning

Underground utility positioning is also an importtant part of intelligent construction technologies (ICT). Accurate identification of subsurface utilities involves a combination of 3D modeling software and underground location technology such as geophysical techniques. More accurate information regarding existing utilities is needed, especially for urban environments, to identify conflicts during design and avoid guess work and digging during construction. In addition, as-built utility plans can be completed for use in future projects and maintenance.
