Private Utility Locating Prior to Directional Boring - Orlando, FL

GPRS was called out to a popular tourist resort in the Orlando area. The customer wanted to perform a directional bore to install a new force main sewer line, and also wanted to do some major digging in a second area. Both aspects of scope were located near a resort style pool, so there was a high density of utilities. We located gas, water, irrigation, communications cables, electric for the pool lighting, high voltage power lines, storm lines, drain lines, and a few unknown utilities as well. These findings were all illustrated in reference map (which is shown below).

Some of the utilities we located were found through radiodetection, while others could only be found through GPR (radar). Radiodetection is a method where we induce a specialized electromagnetic tone (in this case 65 KHz) onto a conductive line. A special receiver is then used to locate that line as far as it carries the signal. This method is highly effective at locating conductive lines, electrical lines, and lines with tracer wires attached. It is not able, however, to locate lines that do not carry and electrical current.

In order to find non-conductive utilities, we utilized our 400 MHz radar antenna from GSSI. This radar antenna sends a 400 MHz electromagnetic pulse into the ground and listens for the echo. The GPR unit can calculate the depth of near-surface utilities by converting the nanoseconds of delay into the distance that the radio waves traveled. A survey wheel is used to accurately mark the location of utilities on the surface of the ground. Although this whole process, which involves advanced physics, custom computing, and months to years of training, the end result is not complex at all. We draw a simple line on the ground, with a straightforward depth clearly written on it, and an easy to follow document showing you where the utilities are running.

Whether your job requires radiodetection, radar, or just good old-fashioned popping manholes and taking measurements (which is still the most accurate method in some cases!) GPRS stands ready to simplify your life and protect your team and budget, by providing clear answers about your project. To order your next GPR investigation, call Dane Short at 407.335.6588.
