Orlando Utility Locating Projects that Penhall Worked On
Analysts identifies metal conduit with utility locating
A trucking company contacted Penhall Technologies to locate a metal conduit for an upcoming project. The line was outside the building, and ran near 3 other metal conduits, making it difficult to isolate. Using a 400 MHz GPR antenna, the analyst mapped out the locations of the conduits coming from the box. He needed to confirm which was which, so that the customer could find the utility they were looking for. The conduit in question had only a single coaxial cable, making inducing a radio frequency difficult. The signal readily bled off onto the adjacent electrical conduits. Eventually, the analyst pushed a line of fish tape attached with trace wire to isolate the frequency. He positively confirmed which conduit was the one the client needed. Penhall Technologies comes equipped with various equipment items to ensure any scope of work we face is completed successfully.
Private utility locating done before trenching
Penhall Technologies was recently hired to perform an outdoor utility locate for a private residence. The property owner wanted to install a drainage pipe from the edge of his property through the street. He was concerned about hitting existing power lines, communications lines, and irrigation. Using the SIR4000 with a 400 MHz GPR antenna, Penhall Technologies was able to locate and mark hazards that would have interfered with his original trenching location. By calling a private utility locator, this property owner not only saved time, but saved money by knowing the exact location of the utilities through his property.
GPR locates water lines
Penhall Orlando utility locating branch was called by a homeowner to locate private utilities in Windermere, Florida. The homeowner was in the process of repairing a retaining wall. Our expert Analyst was able to scan the area using GPR to locate water lines in the dig zone. A sweep of the area with a utility wand ensured that no live power would be damaged during the work. By marking the location of water lines on the surface, the homeowner could safely dig without damaging the utilities. Ground penetrating radar can be used in many other applications such as concrete scanning, detecting voids beneath the surface and underground storage tanks.
Locate underground utilities before digging to install telecommunications lines
Penhall Technologies completed a project at the Orlando Vineland Premium Outlets. A jewelry store needed to add new electrical and data lines for a renovation. This meant that the contractor needed to sawcut through a concrete slab to install. The contractor was concerned about seven conduit lines that extended from the backroom to the sales floor. Penhall Technologies was able to scan the area and locate all the conduits. The project was completed safely, by using both ground penetrating radar (GPR) and a utility wand. GPR is the most accurate method for scanning concrete slab on grade.
Ensure safety by locating all utilities before digging up to 36 inches
Penhall Technologies Orlando office completed private utility locating at a high school football field in Kissimmee, Florida. The contractor was installing a new turf field and was removing 36” of the old grass field. We used ground penetrating radar to locate electrical conduits and drain lines running inside the field perimeter. GPR is capable of locating utilities to a depth of approximately 5-8’. The analyst used a utility wand to locate live power. GPR can be also be used to locate underground storage tanks and subsurface voids.
Large scale utility locating before installing new landscaping with new electrical and irrigation lines
Penhall Technologies completed a large utility locating project in Gotha, FL. The customer was installing new landscaping which included new electrical and irrigation lines along the Florida Turnpike. Penhall Technologies was able to mobilize to the site and locate utilities as directed by the customer. Due to the large size of the project and site restrictions, the analysts completed the scanning by using ground penetrating radar along with a radio detection utility wand and transmitter. The analyst used the 400MHZ GPR antenna to scan the area to an approximate depth of 5’. The utility wand can locate live power and communication lines along with direct connecting to any exposed lines. When directly connected to the line, a transmitter sends a signal through the line, allowing the wand/receiver to locate the utility. The analyst marked the utilities with spray paint and flags on the surface.
