December Technical Webinar: Interpretation of Buried Utility Data

December 10, 2019 @ 12:00 pm - 1:00 pm CST


This presentation will address the differences between utility owner record drawings and the 1 call system accuracy vs. the actual location, as found by an SUE provider. The intent is to help educate all those involved in using utility mapping for design and construction purposes. The presentation will show multiple examples of record drawings and one call marks that are incorrect and or misleading, these errors could have a large impact on design. We will also review how and who depicts the location of buried utilities. For example, surveyors collecting one call marks or a designer with little to no background in buried utility data interpretation.

The presentation will also provide examples of record drawing that can be very deceptive and talk about who is interpreting those records and transferring them to design plans, such as a CAD tech or an E.I.T. This will include both public and private utility record drawings. It will also explain how an SUE provider approaches a utility mapping project, the typical equipment used and how the differences between a one call locator and an SUE utility designator. I will discuss industry terminology with the goal of helping the engineering community better communicate their needs and will tie all of this together with the application of appropriate uses of SUE quality levels.

This webinar will be presented by Glenn Fox from CP&Y Inc.
