Locating Private Utility Lines for Contractor
- Manchester-by-the-Sea, MA

Ground Penetrating Radar Systems assisted a well-known utility contractor with their project in Manchester by the Sea. The scope of the work was to investigate a proposed trench path to locate underground utilities prior to excavation process of a small residential street. When arriving the experienced GPRS technician picked up an unknown utility using the Electromagnetic Pipe Locator at the start of excavation. When the whole area had been covered with a passive sweep the technician proceeded to attempt to locate Underground Utilities by using the transmitter to send a signal through any exposed and or accessible pipes. When sending tone through fire hydrant located on street the technician was able to pick up a signal going down the possible line picked up at the beginning of the project. With the information gathered from the investigation, the technician was able to say that the line picked up was a suspected water line. The skilled technician proceeded to gather more information utilizing Ground Penetrating Radar technology to attempt to give depths to all findings on site. Upon completion, the technician did a walk through with client showing all the findings on site. The water line was located directly on the trench path where the client was to excavate. When they excavated they found the water line in the exact spot the technician had marked.

Locating the Unknowns Subsurface - Woburn, MA

GPRS was called to scan twenty soil borings at the Woburn Mall, prior to drilling soil borings. The area to be scanned was across 13 acres of parking lot directly outside the mall. The well-known Environmental company suspected there might have been utilities running through the areas they wanted to drill. One day before the original date scheduled by the client, there was a last-minute change. Client was notified that no work could be done on site before 10 pm. GPRS was able to accommodate the client’s needs. A technician was able to find a date and time that work for the client so job could be completed within the client new time frame. The job lasted 3 hours and the client was able to pass on the information to the drillers. You can count on GPRS to do our best to accommodate any last-minute changes to your project.

Conduit Locating Prior to Power Line Install
- Waltham, MA

GPRS was called by a contractor to trace out a path of a conduit they wished to use to push a powerline through. The owner of the property did not know where the line was leading to. They had previously run a snake through the pipe, but it got stuck half way through. GPRS was called to use ground penetrating radar technology to investigate if the pipe continued towards the electric manhole. Ground Penetrating Radar Systems was able to trace out the conduit all the way to the electric manhole. GPRS also traced out an unknown vault for the client to give them more information of what was around their area of work. When investigating around the vault, the technician found anomalies that could potentially interfere with client’s project. We then marked out everything in real time directly on the surface for further review. Prior to beginning a project, we want to give our clients as much information as possible of what is underground.

Private Utility Locating with GPR Before Trenching - Worcester, MA

  

Ground Penetrating Radar Systems was called out by a major general contractor to scan for all underground utilities prior to trenching 1500 linear feet to install new drainage and reroute old drains. GPRS was able to use the latest technology in ground penetrating radar to locate any major utilities and unknowns found during path of trench. Utilities were marked out by dig safe previously, but GPRS was able to give client more information on the known utilities. We were able to give depths and precise location of the utilities found. This is important for worker’s safety because they now know the approximate depth to expect utilities while trenching through street. Some of the sewer lines where not marked out in an intersection that client would be trenching through, but GPRS was able to mark them accordingly. By using ground penetrating radar, we were able to confirm the path of sewage that would be crossing the path of the new drainage to be installed. This gave client information on how to adapt to the sewage on the path of trenching.

Ground Penetrating Radar Systems was called out by an engineering company to scan the stem of a T plank inside a parking garage for Boston College. The client needed to drill some holes in order to reinforce the stems. Prior to drilling the client wanted to confirm the location and what reinforcement was inside the stem. GPRS used the latest penetrating radar technology to give depth and location of reinforcement located within the stems. Allowing them to drill with confidence and know what reinforcement was there.
