Importance of Utility Locating
Our technicians have all relevant trainings and certifications such as 40 Hour HAZWOPER and annual 8 hour refresher, Defensive Driving, API and Utility Locating Certification. We also carry Shell, Chevron and UPRR site trainings.
When breaking ground, you may encounter numerous utilities hidden beneath the ground. You may find a variety of buried water, gas or electric utility lines and communication lines. The possibility of damaging these underground utilities exist in every excavation site. Having an unexpected “hit” on existing utilities can be dangerous and costly. This could even cause unwanted project delays, service disruptions, repair costs, and potential fines. The only solution for this is prevention; perform utility locating of the site before digging. Anyone digging underground is required by the State’s law to contact the Call Before You Dig service two days prior the proposed excavation, so that utility locating employees can mark lines on the ground. These calls usually cover the publicly owned utilities and not the privately owned section, usually to the meter. Here at A PLUS UTILITY LOCAING we offer a service to locate the privately owned side of the utilities as well as verification of the placement of lines throughout your projects boundaries
Line Locating Methodology
Conventional Utility Locating Technique
Radio Detection RD 7000
Radiodetection is the process of using radio waves to find the location of something. Electromagnetic equipment are often used consisting of a transmitter and a receiver. Electromagnetic signals are often emitted from metal pipes and cables which are detected by the receiver. These signals can be generated by the transmitter and placed on the pipe or it can be naturally occurring low frequency radio waves and electrical noise.
Ground Penetrating Radar MALA HDR Easy Locator
Because there are different types of materials used in underground utilities, not all types can be detected with conventional methods. Other types of pipes, such as lines composed of plastic, insulated cast iron, clay or concrete, may require other types of detection and location methods. Ground penetrating radar detection is an electromagnetic method that is often used to augment other locating techniques. GPR is a geophysical method that uses radar pulses to image the subsurface. The GPR system consists of an antenna, which contains the transmitter and receiver; and a profiling recorder, which processes the received signal and produces a graphic display of the data. The ground-penetrating radar is able to generate 3D underground images of pipes, power, sewage and water mains. Magnetic locators or metal detectors and magnetometers are often used to locate buried metal objects other than pipes. They operate by indicating the relative amounts of buried ferrous metals. These are commonly used to locate underground storage tanks (UST), buried manhole covers or any subsurface objects with a large ferrous metal content. The current technology cannot assure a 100% detection of every underground utility lines and pipes. There are limitations in every utility locating technique that need to be considered.
