Montgomery Utility Locating Projects that Penhall Worked On

GPR and electromagnetic detection for utility locating

private utility locator Recently, when a contractor needed to dig up and replace a broken water line at a historic hospital in Tuskegee, they trusted Penhall Technologies to provide the locating services needed. The client wanted to prevent damages to steam, water, exterior lighting, telecommunications, and main power lines all run underground. Using electromagnetic detection, coupled with Ground Penetrating Radar (400mhz), the analyst was able to quickly identify their locations without risk of damage to these lines or digging any holes. This campus is very old. Therefore, many lines were underground upon replacement, leaving many unanswered questions. Armed with this information, the customer could select the best route to run the new lines and save time and money.

Detect subsurface utilities and storage tanks for a gas station

The client wanted to perform the service prior to an installation of a new perimeter fence. By conducting the utility locating, the project remained on schedule. Ultimately, the client only had to close the gas station for 12 hours during non-business hours.

Before trenching began, the homeowners called Penhall Technologies to perform underground utility locating on a 20’x30′ area. The analyst marked water and electrical lines and provided the homeowner a written field report to share with the pool company. This ensures safety for the client and those working on his project.
