About this file
This is a Ground Penetrating Radar Services (GPRS) job summary report for underground utility location work performed at 3001 W Blue Starr Dr, Claremore, OK on July 24, 2024. The work was performed for AIMRIGHT Testing Engineering LLC to clear three soil boring locations prior to drilling. The report details the equipment used, including an underground GPR antenna (250-450 MHz), electromagnetic pipe locator, and GPS unit with 4-inch accuracy.
The scope involved locating underground utilities at three soil boring locations with an approximate GPR effective depth of 3 feet. The client had completed an 811 locate request but did not provide drawings. The results indicate one unknown utility line was located near a soil boring location, and a white box was painted on the surface to mark a safe drilling area. The report includes supplemental information about common utility locating limitations and marking conventions. This GPR survey appears to be preliminary site preparation work related to a larger IHS construction project for a new clinical modular building at the Claremore Indian Hospital location.

GPRS Project Manager: Jay Tate
Thank you for using GPRS on your project. We appreciate the opportunity to work with you. If you have questions regarding the results of this scanning, please contact the lead GPRS project manager on this project.
EQUIPMENT USED
The following equipment was used on this project:
• Underground GPR Antenna: This GPR Antenna uses frequencies ranging from 250 MHz to 450 MHz and is mounted in a stroller frame that rolls over the surface. Data is displayed on a screen and marked in the field in real time. The surface needs to be reasonably smooth and unobstructed to obtain readable scans. Obstructions such as curbs, landscaping, and vegetation will limit the efficacy of GPR. The total effective scan depth can be as much as 8’ or more with this antenna but can vary widely depending on the soil conditions and composition. Some soil types, such as clay, may limit maximum depths to 3’ or less. As depth increases, targets must be larger to be detected, and non-metallic targets can be challenging to locate. The depths provided should always be treated as estimates as their accuracy can be affected by multiple factors. For more information, please visit: Link
• EM Pipe Locator: Electromagnetic Pipe and Cable Locator. Detects electromagnetic fields. Used to actively trace conductive pipes and tracer wires, or passively detect power and radio signals traveling along conductive pipes and utilities. For more information, please visit: Link
• GPS: This handheld unit offers accuracy down to 4 inches; however, the accuracy achieved will depend on the satellite environment at the time of collection and is not considered survey-grade. Features can be collected as points, lines, or areas and then exported as a KML/KMZ or overlaid on a CAD drawing.
