As a contractor, we recognize you are faced with crucial decisions on a daily basis. For example, when you’re building a new structure or renovating an old building, there are countless subsurface hazards that need to be accounted for prior to excavation, core drilling and saw cutting.

If you choose to forgo employing GPR services, the result could be devastating to your company. There are compounding effects that can impact safety performance, project schedules and job site financials that could throw the entire project into turmoil.


Your Bottom Line

Imagine if you fail to schedule a utility scan, and an unknown utility becomes damaged during an excavation. Maybe it’s a simple fix. Maybe not. It’s on you to correct it, and that expense will come out of your profit, cutting into an already thin margin.

Lost Business

The bread and butter of any construction company is repeat business. The last thing any company wants is a tarnished reputation because of a botched schedule or construction site accident related to you not doing your due diligence. With the multiple technologies GPRS employs to scan for buried utility lines, reinforcing steel, or embedded electrical conduits, there is no reason to risk losing good customers over ignoring a fundamental project checklist item.

Unexpected Downtime

It can drastically change your project timeline if you accidentally cut a post tension cable or sever a gas line and need to get it fixed. It may only be a day or two. Still, it could be longer, presenting the possibility of compounding scheduling delays occurring due to specific tasks needing to take place before the remaining functions can be completed. This, in effect, can impact your bottom line and hurt your profit.

Why not consider the best when you hire a subsurface utility locating and concrete scanning company?

Unlike companies who are limited to one service, at GPRS we help you to visualize the built world of your campus and facilities by providing 7 different core services. These services provide you a one stop shop for all your above and below ground mapping and modeling needs. We specialize in utility locating, concrete scanning, leak detection, 3D laser scanning, video pipe inspection, and drone imagery, and our experience and expertise are second to none.

Consider that we built the state-of-the-art GPRS Academy, where every GPRS Project Manager must complete an extensive training program consisting of 80 hours of classroom/hands-on training and 320 hours of mentorship in the field before performing field services on your job site. Our staff includes a full-time training and safety director to ensure all of our Project Managers are skilled in operating our equipment with high levels of competence and confidence while always being conscientious about safely performing our duties.

GPRS is one of the first companies in the country to focus on concrete scanning and utility locating, primarily using ground penetrating radar. Since we started in September 2001, we have built a nationwide network of offices, with our team strategically placed in every major metropolitan area in the United States. Since our founding, we have worked on some of the country's largest and most significant construction projects. We stay busy. On average, each of our Project Managers performs 300 jobs per year.

Remember: We are the best at what we do because it is all we do. When you need to map what lies below and above the surface, contact the nation's best one-stop shop. Your project's success could depend on it.

We Minimize Risk

Just one utility strike or damaged concrete structural element can be the difference between a simple renovation and a prolonged project that incurs costly damages, delays, and even injuries. GPRS utilizes multiple cutting-edge technologies to get a clear picture of what’s underneath the surface or behind the concrete. It’s not just about the tools…It’s about the individual operating them. When these technologies are in the hands of GPRS Project Managers—the industry’s most experienced field technicians—you get an immediate and accurate report of subsurface elements, allowing you to complete your projects safely. Our Project Managers are held to the highest industry standards—ours.

Safety Conscious

The technologies used by GPRS are non-destructive, non-intrusive, and non-hazardous. They not only help you avoid subsurface hazards, but also that your personnel will be safe during testing.

Our world-class field support training specialists educate all GPRS Project Managers in the state-of-the-art GPRS Academy. GPRS Project Managers become equipped to perform the most comprehensive locates in the industry by being trained in subsurface investigative technology, ensuring you receive quality results on your project.
