///you can’t afford damages, clashes, reworks, accidents, AND budget overruns, AND neither can we.

At GPRS we believe that data control = damage control and we are committed to the pursuit of 100% subsurface damage prevention – on every job, in every market, nationwide.

That’s why every one of our 500 national “boots on the ground” team of elite Project Managers are trained in Subsurface Investigation Methodology (SIM). SIM elevates a mere technician to an expert professional with the cross-technology training and industry-leading processes that can locate, map, capture, measure, and scan your entire site or facility, above and below-ground, to provide you with the real-time actionable information you need to plan, design, manage, dig, and build better.

GPRS is the only company in the U.S. that can capture your entire site or facility, above and below-ground, to provide you with accurate as-builts, private and public utility maps, 2D CAD drawings, and 3D photogrammetry and Building Information Models (BIM) that can integrate surface and subsurface existing conditions and construction progress capture to provide cloud-based, digital mapping & modeling solutions for the construction, architecture, engineering, facility management, and related industries via SiteMap®.

In pursuit of 100% subsurface damage prevention | GPRS


Every decision you make on a job site can cost time, money, and even lives. That’s why GPRS maintains a consistent 99.8%+ accuracy rate in utility locating and concrete scanning & imaging. Because it’s our job to help you keep your jobs on time, on budget, and safe. Our nationwide team of elite Project Managers aren’t just expert technicians – they are consultants who help you get what you need to do the job right, and safely.


GPRS strives for 100% subsurface damage prevention, boasting a 99.8% accuracy rate nationwide. Our 500+ Project Managers employ the Subsurface Investigation Methodology (SIM) for utility mapping, concrete scanning, sewer camera inspection, and 3D laser scanning, ensuring consistent, high-quality results.


With 500+ SIM-Certified project managers, GPRS offers nationwide support for Visualizing the Built World. Our Rapid Response program ensures quick deployment across all US markets. Specializing in utility locating, we excel in multi-site projects, providing concrete scanning, utility locating, and CCTV sewer scoping. Benefit from our extensive experience and nationwide coverage for seamless infrastructure visualization.

Field to Finish

GPRS guarantees a smooth field-to-finish process with 99.8% accuracy. Our project managers employ various tools for data collection, including ground penetrating radar, CCTV cameras, and LiDAR. In-house mapping creates deliverables stored in SiteMap®. Upon utility locate completion, SiteMap® generates site maps in .pdf, .kmz, and .shp formats, free with subscription.


GPRS provides unmatched existing conditions documentation – above and below-ground – to help you plan, design, manage, and build better.

Avoid mistakes, downtime, and costly reworks with accurate existing condition documentation provided by our team of SIM-certified Project Managers; update stakeholders and communicate clearly with construction progress capture and digital walkthroughs to document milestones and collaborate better.
At GPRS, we believe that Data Control = Damage Control. And our goal is to put you in control of your data now and in the future.

Eliminate outdated paper records and inaccurate as-builts with accurate, layered, and digitized information on every centimeter of your project, available at your fingertips from anywhere, 24/7 and securely sharable via our SiteMap® platform.

Keep your team informed, design maintenance schedules and workflows, plan for emergencies, and know where it is safe to cut, core, drill, or dig before you break ground.


Subsurface Investigation
The industry standard recommends 8 hours as a minimum for training and 60 hours practicing GPR to become certified NDT Level 1 in Ground Penetrating Radar. By contrast, SIM requires 320 hours of mentorship in the field prior to 80 hours of classroom/hands-on training.

In addition, the unique combination of classroom training and on-site supervised field training reinforces what a Project Manager encounters on the Job. The SIM curriculum allows them to go deeper into the technical aspects and knowledge needed to perform their jobs at the highest level.
Subsurface Investigation Methodology (SIM) requires multiple technologies to be used. With any Investigation, more data points yield the best outcome.  When SIM-qualified technicians   locate a subsurface target such as a pipe, utility, or reinforcement   with more than one technology, it confirms the accuracy of the locate. This redundancy also reduces the likelihood of missing a buried target. Redundant results bear more data points; by locating pipes  and other targets with different methods utilizing each tool's strengths, technicians reduce the risk of missing key site information.

The SIM Certification is a tested process that allows Project Managers to acquire accurate and repeatable results. SIM is similar to a machine that requires multiple gears all working in unison for it to function properly. One of the most critical gears and steps in the SiM process is the repeated methodology that Project Managers must know for each project.

A solid, repeatable methodology guarantees that a concrete scanning, utility locating, or video pipe inspection project can be performed by a seasoned professional, and also by a new-to-the-business technician. When the SIM methodology is followed, It allows technicians to achieve the same results, regardless of their experience in the field.
GPRS Academy Logo | GPRS


Over the past two decades, GPRS has set the standard in training and quality service. The goal of achieving 100% Subsurface Damage Prevention compelled us to surpass typical manufacturer training. The launch of GPRS Training School almost a decade ago widened the gap between us and the industry norm.

Combining classroom instruction, mentorship, real-world sites, test slabs, and training slabs contributed to our scanning accuracy rate of 99.8%. However, in our relentless pursuit of perfection, we raised the bar. With the completion of GPRS Academy, that vision is one step closer to reality.
3,000 sq ft continuous concrete training slab complete with real-world scenarios like post-tension cables, rebar, electrical conduits, columns, and beams.
Training slab can be sectioned off into 4 separate classrooms that allow for advanced training – each classroom progressing in difficulty.
3,000 sq ft indoor simulated gas station that is complete with USTs, buried utilities, light poles, and other related piping
Simulated elevator shaft complete with curving and terminating post-tension cables, extra reinforcement, and densely spaced electrical conduits.
3,000 sq ft slab-on-grade training area that is complete with conduits, reinforcement, shallow utilities and more.
Video Pipe Inspection training area that features sewer and water lines, including sewer laterals for training with VPI cameras.
