The 2017 PWX has it all - from education sessions to an exhibit floor full of excited vendors who can't wait to show you the latest solutions your community's been looking for. Make plans today to join your peers in Orlando for the “Best Show in Public Works” August 27-30…

This presentation will provide a basic overview of ground penetrating radar (GPR) and evaluate its emerging role in the damage prevention industry for protecting critical infrastructure and public works. Attendees will leave with an understanding of how the technology works, what utility locate data look like and how to interpret it, how GPR compares to other locating equipment, and the role of GPR in damage prevention with specific steps to maximize a successful GPR survey.

In the overview of GPR technology, this presentation will summarize the mechanism that GPR uses to image the subsurface and then explore the two main variables that drive depth of location: antenna frequency and material properties. Next will be a review of several case studies from utility locating projects showing both 2D and 3D data. The comparison of these two views will help attendees understand the benefits and limitations of both visualizations. Then I will compare GPR to EM locators, focusing on the strengths and weaknesses of each and ultimately making the case that these are complimentary mapping techniques. Finally, this presentation will present a variety of ways that GPR can be used on locate projects including those with non-ideal conditions and offer a few steps to enhance the likelihood of a successful survey.

The people who will benefit most from this presentation are managers of government agencies and engineering firms that conduct damage prevention projects and utility locates as well as those that are considering GPR technology or want to maximize its potential. In addition, locate technicians will find the discussion of GPR basics and the comparison to other technology useful.

Learning Objectives:

  • Investigate buried utilities to minimize potential damage
  • Explain the limitations of GPR to clients and agencies
  • Recommend appropriate use of GPR in a variety of conditions
