The Next Generation of Underground Mapping Best Practices: Advanced Utility Locating and Mapping Technologies to Improve the Accuracy and Speed of Utiltity Locating for Digital Twin

As one of the oldest American cities, Boston holds a rich history and culture that runs not only through the streets but also beneath them. Many of the large underground infrastructure projects completed between the late 1890s and the late 1920s in Boston are still in use. The preservation of this infrastructure and the insights gleaned from the utility locating and mapping practices used to create it provide valuable lessons in how to maintain standards of excellence. While 811 is an integral part of underground damage prevention, Subsurface Utility Mapping using traditional land survey, utility locating, vacuum excavation and multi-sensor mobile mapping platforms should also be utilized in locating and mapping 200 years of underground facilities.

The presentation will highlight a recent utility project managed by DGT and demonstrate how the use of mobile mapping platforms can work in unison with traditional methods and 811 practices to map large-scale urban areas.

Featuring

Michael A. Twohig is a Subject Matter Expert in the field of Subsurface Utility Mapping (SUM). Michael has more than 36 years of industry experience across the US, Australia, India, and Europe with a focus on the integration of traditional utility locating procedures with land survey best practices. As head of SUM at DGT, Michael spearheads the firm’s subsurface utility locating, 3D utility mapping and subsurface utility damage prevention programs. Michael is currently developing Multi-Sensor Mobile Mapping platforms using the next generation of multi-channel, multi-frequency Ground Penetrating Radar (GPR) systems for the SUM and void detection industry. In the span of his career, Michael has authored more than 40 articles relating to utility mapping, underground damage prevention, and utility industry best practices, and he is a frequent speaker at international conferences such as the Common Ground Alliance CGA, SPAR, Hexagon and the international Lidar conference ILMF and most recently GEOBIM in Amsterdam. Michael has also presented SUM best practices at military, transportation, commercial and GITA conferences. One of Michael’s greatest achievements is the advancement and development and implementation of new 3D deliverables for geospatial projects, integrating LiDAR, utility locating systems, GPR, infrared, land surveying, and multi-sensor platforms to provide high quality, reliable and accurate data for CAD, GIS and BIM delivery format.
