Locating utilities on private property is crucial when performing services that require directional drilling, geotechnical services, Phase I or Phase 2 investigations, environmental drilling and sampling, locating underground storage tanks (UST), soil borings, installing monitoring wells, or site remediation. GPRS can quickly mobilize to your job site and locate critical utilities or USTs that could be in conflict with your drilling or excavation area. The scope for GPRS when working in the environmental sector can vary greatly. We are called to clear soil boring areas at former gas station and laundromat/dry cleaning sites and even to map underground utilities for entire communities that are a part of a SuperFund remediation process. Whether large or small, GPRS is equipped to accurately locate and map underground facilities for any project.

We are able to accomplish this by using multiple locating technologies as outlined in the SIM Specification. By using a combination of different locating technologies such as ground penetrating radar (GPR) and electromagnetic induction, utilities that lie the path of your geoprobe can be found. When performing directional drilling, directional boring, in-situ or ex-situ soil remediation, or horizontal remediation well drilling, knowing the vertical and horizontal position of utilities is a non-negotiable. Call GPRS today to learn about our industry-leading locating methodology that has produced results exceeding 99% - for the nearly 20 years.

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.
