Here in Apopka FL at the Dewar Nurseries, Trinity was called to perform a full Utility Designation using Ground Penetrating Radar (GPR) and a variety of Electromagnetic Locating Devices for a Foundational Services company performing 14 soil boring locations. We were assigned to designate locatable utilities within 15 feet radius of the marked locations. Irrigation lines being of main concern due to the active nursery.Trinity came to safely and accurately mark out the PVC irrigation line, as well as identify how far the lines were within radius of all marked locations. While identifying the location, our GPR was able to detect the material type and the depth with all findings. We then, performed a walk through with the client after completing all scans. The client was satisfied with the timely communication, turnaround time, locate, insurance of safety, and accuracy provided by Trinity, including our field sketch provided at no extra cost. The Electromagnetic Locating consisted of direct connection, clamping, andinduction using both the Radio Detection Transmitter and the Receiver. Grid patterns were also performed in Passive Modes with the EM Receiver,specifically to detect subsurface metallic conduit, copper wiring, and live electrical lines (60 Hz). GPR Scans were performed in a similar grid pattern,purely detecting changes in density and discovering anomalies that are nonconductive to EML. The purpose of this Utility Scan was to detect Electric lines, Communications lines (Phone, Cable,FOC), Water lines, Gas lines, Sewer lines, and Force Mains. All findings were marked with spray paint and flagged according to the AWPA Uniform color code with periodic, approximate depths. We performed a walk through with the Project Manager on site before location designation began, as well as upon completion.We thoroughly enjoyed providing our services here at Dewar Nurseries to ensure the safety and efficiency of all parties involved with this project, and we look forward to many more to come! At Trinity Subsurface, we can make sure any obstructions within the soils are found when performing an underground utility locate. Whether your project is to locate prior to directional boring, digging,potholing, or trenching, we will be able to locate all obstructions within all types of soils. These obstructions include water, gas, sewer, electric, fiber optic,and drain lines, irrigation and unknown pipes, and any other obstructions within the soil. We are also able to locate utilities that run directly below the concrete or asphalt. Using our state-of-the-art utility locating equipment,we can see up to 3 - 10 feet depending on the makeup of the soil and the moisture within it. We will use several different types of equipment including radio detection, ground penetrating radar, sondes, split box and several others depending on the project and what is needed to help you understand what’s underneath.  We can then provide a detailed written report for your project, or just mark it out on the surface of the ground with paint, stakes,or pin flags. 

Our training program for underground utility locates is very thorough and one of the best in the industry. When our technicians are on site, you can rest easy knowing that they have the best training and equipment for your utility locating project. Maintaining the safety of your people and the subcontractors working on your project is the number one priority of Trinity Subsurface.
