Underground_Utilities_Locate.jpg

Several full-service utility surveying companies have contacted Ground Penetrating Radar Systems, LLC. over the years. The surveying companies are frequently looking for an edge over their competitors and ground penetrating radar can often provide that advantage. In this case we were contacted by a surveying company to mobilize to a paper mill located in Jacksonville, FL. The mill had an area roughly 250’ x 700’ in size that they wanted to survey to locate old utilities, concrete foundations, a live fire line, and a live water line. This area of the facility was extremely dilapidated and decomposing. Large abandon buildings, foundations, etc. were protruding from the ground and debris was scattered everywhere. GPRS is often faced with the challenge of surveying difficult terrain and this site was no different.

GPRS-Concrete-Slab-in-Seattle-Washington.jpg

A large construction company had a project in West Seattle building a new apartment and retail complex. There was a need to install new floor outlets throughout the building, which meant concrete sawing and coring was needed. Prior to beginning the sawing and drilling processes, the contractor contacted Ground Penetrating Radar Systems of Washington (Portland) to scan the floors to locate the reinforcing steel and any conduit present.

GPRS-New-York-Office-Locates-Utilities-at-One-World-Trade-Center.jpg

Ground Penetrating Radar Systems, LLC. was contacted by a contractor that needed to know the location of utilities prior to excavation earlier this month. The client's primary concern was to determine the location of any utilities or other near-surface items within the excavation area prior to digging so that they could either relocate either the excavation area, or the utility lines. The project consisted of clearing three 20’ x 20’ areas. Utilizing the latest in GPR and Radio Detection technology, Joe Bernarducci of the New York City Office scanned the site and was able to mark out several utilities traveling through the proposed areas. All of the utilities that were located were then marked directly onto the service in real time while GPRS was on site. The use of ground penetrating radar allowed the client to stay safe while digging and helped to keep them on their tight completion schedule. With the professional services provided by GPRS, no utilities were struck during the excavation of the three areas allowing the client to stay safe on this project.

Ground Penetrating Radar is often used to determine the presence of any underground storage tanks. We recently were scanning a old service garage in New Jersey to determine if there were any abandoned tanks or lines in the sub-grade.

Through the process of taking scans on one foot centers in a grid pattern we found several combinations of connecting reactions. Our project manager detected a deep circular disturbance about 20” wide that was connected to a pipe that would lead to a steel plate embedded into the slab. We found this pattern several times in the service garage. The owner of the garage was on site and made and recalled that the original garage used a piston system to elevate vehicles in the service garage. With the technology of GPR we were able to determine the location of the old pistons, and the lines that connected them to the hydraulic lifts. In this instance we were able to confirm that the pistons had been removed and there were no longer any UST or pistons below the surface.

In the picture to the side you can see our markings where there...

The pictures you see below are from a local attraction in Orlando, FL. The demolition contractor was removing a curb when they unknowingly broke a main feed line for the sprinkler system. This would normally not have been something difficult to remedy. However, they did not know where the shut-off valve was for the system. With this problem hundreds of gallons of water were wasted and the ground will have to be repaired prior to work continuing.

This is not an uncommon issue on job sites today. To cut cost contractors are performing site work, demolition and excavation without having a proper utility locate performed. Most argue that it is a private property and therefore the local “one-call” services will not perform the scan. This, however, is where Ground Penetrating Radar Systems really shines. We work in all conditions providing one of the most comprehensive and accurate utility locates available.

We can ensure you that your project will be safe and more cost effective before you start digging or excavating....
