Upper Marlboro Utility Locating Projects that Penhall Worked On

Identify vital utility lines before remodeling to ensure safety during construction

locate utilities before undergoing remodeling to commercial propertyA customer in Bethesda, MD recently hired Penhall Technologies for our underground utility locating services. The client wanted us to locate and mark their utility lines for them before they decided to do any type of remodeling to the commercial property they had just purchased.  Our expert analysts used GPR (ground penetrating radar) to locate all lines. After using the GSSI 400MHz antenna, the utility cart pictured, the analyst also used his RD7100 equipment to corroborate the location of the utility lines. In total, they found water, gas, and power lines.  The analysts marked all the utilities in the designated color. The clients are now well on their way to remodeling their office in a safe, and timely manner.

GPR use to scan floor to locate utilities and conduitPenhall Technologies was asked to perform GPR scanning at a large theater complex in Silver Springs, MD. The client wanted to locate buried plumbing lines on the first floor of before his remodeling project could begin. After arriving on site, our analysts were able to locate the pipes with the GSSI 400MHz. They marked the utilities found for the construction crew coming for the remodeling job. This prevents utility damage during construction and saves the client money and time.

Locate all underground utilities before undergoing tree removal

locate underground utilties before undergoing tree removalRecently, Penhall Technologies was hired by a homeowner in Port Deposit, MD. The client needed to find water and power lines in one acre of land before they could remove some trees. The analyst arrived at the property and scanned all possible underground utilities with the GSSI 400MHz antenna. After scanning, the analyst marked all detected subsurface utilities. This avoids damage in the client’s property during excavation of the trees.
