Excavation Encroachment Notification (EEN) System 

GTI is using real-time GIS technology and cellular-connected location and motion sensors placed on construction equipment to reduce damage from excavation activity. Real-time tracking of construction equipment, gas system infrastructure GIS data, and activity characterization algorithms are used to alert stakeholders to potential damage from active excavations.

GTI has worked extensively with Operations Technology Development (OTD), Pacific Gas & Electric (PG&E), and other utilities to develop and demonstrate the technology. GTI successfully deployed 150 devices in an excavation encroachment notification (EEN) system pilot project with PG&E as part of a California Energy Commission grant. Researchers were able to assess excavation activity and combine GIS data to provide an accurate algorithm to significantly reduce the occurrence of false-positive results in the characterization of field activity. Based on positive response, PG&E will continue to use the devices after the field test ends to help bring the technology to market.

A commercialization agreement has been signed with Hydromax USA to offer the system on a monthly subscription basis as UtilAlertTM. It is anticipated hardware will be available for shipment by early second quarter 2019.

UtilAlert™

Real-time tracking of construction equipment, gas system infrastructure GIS data, and activity characterization algorithms are used to alert stakeholders to potential damage from active excavations taking place around utility assets. The system will alert the operator of excavation equipment of the presence of buried facilities in the work zone and can be used to establish geofencing boundaries for notification of excursions.
