The variance between different types of facilities in the US is extreme. The complexity of a large hospital campus is matched in complexity at facilities like airports, military bases, manufacturing plants, recreation centers, college campuses, power plants, and refineries. One thing that all of these different types of facilities share is a maze of underground utilities, pipelines and conduits the are critical to plant operations. If these utilities are damaged during the excavation, directional drilling or digging process, damage can occur, people can be injured, reputation can be damaged, costly shut downs can take place, and budgets can be blown. In addition to the concern of line strikes, knowing the whereabouts of underground facilities is key for the planning phase of renovations and new construction. One of the best ways to ensure damage prevention is to have a detailed as built map of all underground utilities on public and private property.

Leaders in cable avoidance, GPRS utilizes multiple methods of locating technology to identify underground utilities prior to construction beginning. An EM locating device (sometimes referred to as a CAT & Genny tool) is used to passively trace utilities. This tool is also used to attach directly to utility lines to trace their path, following a signal. Video pipe inspection tools such as push cameras, lateral launch cameras, and CCTV camera crawlers are used to map in the location and interior condition of sewer and water pipes. Ground penetrating radar is added to the methodology to discover unknown buried lines, determine utility depth and locate underground storage tanks. Whether using GPRS to locate utilities prior to digging or to create an updated as-built utility map, you are hiring the industry-leader in utility damage prevention.

GPRS understands that clear, understandable, and consistent pricing is a big deal. Our nationwide footprint allows us to streamline our costs on a nationwide basis, we are sure to craft a cost structure that makes sense for the scope of work. Rather than send a blanket rate sheet, we consultaively compose pricing plans for each project.


Every campus, site and facility have different challenges. Since our inception, GPRS has completed hundreds of thousands of projects and relies on that experience when crafting a site-specific plan for safety, scanning and reporting. With the SIM Specification as our guide, we will craft an individualized approach to each and every project. From facility mapping, locating prior to excavation, to performing one-call locating - GPRS will perform the right service for your scope of work.

One Call Program

GPRS exceed industry performance when it comes to the accuracy of our utility locating. Our team of Project Managers can continue the support of your project by crafting a one-call program from when your project transitions to the O&M phase.

Public Property

Damage prevention is critical when excavating in a public right-of-way. Using the 811, call before you dig system, is an essential step to take when trying to avoid underground utility strikes. It's the law! GPRS is able to contract and perform one-call type utility locating for your underground assets.

Private Property

A utility locate on private property is not complete until a private utility locator like GPRS has been called to comprehensively locate the entire campus. GPRS can create a one-call type program for your facility or campus in the case that you have utilities that lie within public property.


GPRS can place our highly trained PMs within your facility or campus to perform utility locating and concrete scanning services. When our PMs are placed within a facility, many benefits realized when compared with our standard services. Our schedule is at your disposal, there is familiarity with site intricacies, and we can manage as-built drawings for the entire site.

As-Built Drawings

As-built utility drawings don't always show the current underground conditions of a site. Drawings that are produced in the design-phase of a project don't always reflect the exact location of underground utilities. Over time, due to renovations, repairs, and additions, as-built drawings become out of date. GPRS PMs are able to update as-built drawings so that they reflect the actual vertical and horizontal position of underground facilities.
