GPRS Locates Utilities at a Hospital in IL.

GPRS Hospital Utility Locate – Chicago, IL

“Time is a primary currency traded on any given construction project. At Ground Penetrating Radar Systems, our everyday efficiency in operations allows us to respond to the immediate needs of our customers, often within 24 hours or less.” (

A Chicago contractor needed to locate the public utilities at one of their project sites. They plan on setting up emergency tents for potential COVID-19 holding areas and testing. They wanted to do this without drilling a post into a utility that could shut down power or communication to the hospital, as well as potentially harming a worker in the area. The contractor hired Ground Penetrating Radar Systems (GPRS) to come in and mark out the public utilities in the area. The scope of the project consisted of scanning a 100 square foot area.

Using the SIR-3000 we were able to locate and paint out the path of the water (Blue), communication (Orange), and in other areas we located the electric, gas, light pole, and storm drain/ sanitary lines. The utilities were clearly marked out with different colored paint so the contractor could tell each utility apart. Thanks to our service the contractor was able to set up the emergency tents. All of our project managers are OSHA certified and come to every project site with the correct PPE. GPRS is also able and willing to work nights to accommodate all customer needs.

Our state of the art GSSI GPR equipment can send signals into concrete that send data back in real time. The signals are safe for workplaces so there is no need for stoppage in work for floors below or around scan areas. The specific equipment that was utilized for this job was the GSSI 400 MHz GPR Antenna. Using the 400, we are able to scan up to 6ft into the ground and more accurately detect any metal utilities, voids, or other unknown anomalies in the ground. GPRS also uses the RD-8100 Locator to locate live power and radio frequency (RF) signals underground. We can also detect utilities in or underground via induction or conduction with an exposed or known surface utility line.

GPRS technicians are commonly called to scan for utilities, voids, underground storage tanks (UST’s), or even unmarked graves.

At GPRS safety is one our #1 priority. When digging or drilling the last thing you or our technicians want is to hit a surprise utility in the ground. While you may think that there is nothing in the ground, there are an unfortunate number of clients that call because they were proven wrong. The price of one of our technicians is well worth the price compared to the costs of repairing a mishap later on.
