Technologies such as ground penetrating radar (GPR) or acoustic locating for detecting underground utilities involve directing some type of signal, electromagnetic or acoustic, into the ground and measuring the reflection off underground objects. A major challenge for these techniques is... Continue reading

Many of the technologies for detecting underground utilities and other infrastructure involve shooting some type of signal, electromagnetic or acousic, into the ground and measuring the reflection off underground objects. A major challenge for these techniques is attenuation. Ground conditions... Continue reading

According to statistics compiled by the Common Ground Alliance (CGA) the process by which underground utilities are located (detected and marked) are responsible for 28% of incidents of damage to underground infrastructure during excavation. To better understand locate issues the... Continue reading

Knowing where things are underground has become important enough that in a number of jurisdictions around the world including the Netherlands, Singapore, and the U.K., initiatives are underway to create national digital twins which include below-ground infrastructure. Recently there have... Continue reading

Inertial locating is an innovative technology that is used to accurately map underground pipe networks. But to date the technology has required non-pressurized pipes. Now a PHMSA-sponsored project has demonstrated that the technology can be applied to small-diameter pressurized gas... Continue reading

Number of respondents: Contractors, statutory excavators, and roads authorities A survey of stakeholders in the construction industry has reported that respondents identified unreliable (inaccurate, incomplete) records as the biggest source of risk of damage to underground infrastructure. The survey elicited... Continue reading
