Before a project can reach new heights, it must be grounded in certainty. GPRS provides accurate data from below the surface to the top of the skyline, giving you a solid foundation for success.
Growth Begins Below the Surface
In construction, engineering, and infrastructure development, success starts with discovering what lays below. Before a single shovel hits the ground, understanding the subsurface environment is critical. With cutting-edge technology and a mission to eliminate subsurface damage, GPRS helps organizations lay the literal and figurative groundwork for safe, efficient, and scalable growth.
Whether you're building a skyscraper, expanding a hospital, or retrofitting a university campus, GPRS provides the clarity you need to move forward with confidence.
The Hidden Risks Beneath Every Project
Every construction site hides a complex web of utilities, pipes, and structural elements. Striking a gas line, severing a fiber optic cable, or damaging post-tension cables can lead to:
· Costly delays
· Injuries or fatalities
· Regulatory fines
· Reputational damage
These risks are not just theoretical; they happen every day across the country. A big part of why GPRS exists is to prevent them.
A Partner in Precision
GPRS is more than a service provider; we’re your strategic partner in project planning and risk mitigation. Our suite of services is designed to give you a complete picture of your site – aboveground and below-ground– so you can design and build with certainty.
Utility Locating
Using advanced ground penetrating radar and electromagnetic locating, GPRS identifies underground utilities with a 99.8% accuracy rate. This service helps teams dig safely, avoid costly utility strikes, and maintain project timelines.
Concrete Scanning
Before any coring or cutting begins, GPRS performs concrete scanning to detect embedded objects such as rebar, conduits, and post-tension cables. This ensures structural integrity and protects both workers and infrastructure.
With our Green Box Guarantee, you gain an added layer of assurance. When we mark an area with a green box, it means our experts have verified it as clear and safe to cut. This system gives your team the confidence to proceed, knowing that safety and accuracy are backed by industry-leading standards.
Video Pipe Inspection
GPRS uses robotic camera systems for video pipe inspection, allowing teams to assess the condition of sewer and stormwater systems. This service identifies blockages, cracks, and cross bores that could otherwise lead to costly repairs or project delays.
3D Laser Scanning
With high-resolution 3D laser scanning, GPRS captures every detail of a site to create accurate digital twins. This data supports precise planning, clash detection, and seamless integration with Building Information Modeling(BIM) systems.
Leak Detection
GPRS employs acoustic and thermal imaging technologies for leak detection, pinpointing hidden leaks in water systems. This proactive approach helps clients prevent water loss, reduce utility costs, and avoid infrastructure damage.
Turning Data into Decisions
One of GPRS’ most powerful tools is SiteMap® (patent pending), a cloud-based GIS platform that stores and visualizes all subsurface and structural data collected on a site. Designed to bridge the gap between field data and actionable insights, SiteMap empowers you to plan, build, and manage better throughout every stage of your project lifecycle.
With SiteMap, clients can:
· Access real-time data from any device – whether in the office or on-site, users can instantly view and interact with utility maps, concrete scans, and 3D laser models.
· Share annotated maps with stakeholders – collaborate seamlessly with engineers, contractors, and facility managers using intuitive tools for markup, notes, and version control.
· Layer multiple data types – combine utility locating, concrete scanning, and 3D laser scanning data into a single, unified view for comprehensive spatial awareness.
· Plan future projects with historical context – maintain a digital record of all subsurface investigations and structural scans, enabling informed planning, risk mitigation, and compliance over time.
More than just a data repository, SiteMap becomes a living asset, supporting long-term growth and maintenance:
· Preventative maintenance by identifying aging or at-risk systems before failure occurs.
· Regulatory compliance through accurate documentation and traceability.
· Capital planning by visualizing infrastructure needs and prioritizing investments.
· Emergency response with quick access to critical utility and structural information.
By turning complex field data into clear, actionable intelligence, SiteMap helps organizations reduce risk, avoid costly delays, and build with confidence.
The SIM Advantage: Subsurface Investigation Methodology
Every project manager is trained in the Subsurface Investigation Methodology (SIM) – a process that standardizes how data is collected, interpreted, and reported.
SIM ensures:
· Consistency across all GPRS teams
· High-quality, repeatable results
· Confidence in decision-making
This methodology is a key reason why GPRS has earned the trust of Fortune 500 companies, government agencies, and top-tier contractors nationwide.
Laying the Groundwork for Scalable Growth
Growth isn’t just about building bigger – it’s about building smarter. GPRS supports scalable growth by:
· Reducing rework and change orders
Accurate data upfront means fewer surprises later.
· Improving safety and compliance
Avoiding utility strikes and structural damage protects workers and meets regulatory standards.
· Accelerating timelines
With fewer delays and clearer planning, projects stay on schedule.
· Enhancing collaboration
SiteMap makes it easy for teams to work from the same data, no matter where they are.
Real-World Impact: GPRS in Action
Case Study: Compressor Station Protection
At a critical natural gas compressor station, excavation was planned for a new pipeline installation. GPRS was called in to perform utility locating and concrete scanning. Their team identified several unmarked utilities, including a high-pressure gas line that was dangerously close to the dig site. By mapping these utilities in advance, GPRS helped prevent a potentially catastrophic incident, saving the client from costly repairs, environmental damage, and operational downtime.
Case Study: Nashville Restaurant Sewer Backup
A restaurant in Nashville was experiencing persistent sewer backups that traditional methods failed to resolve. GPRS deployed advanced video pipe inspection and utility locating technologies to investigate. They discovered a collapsed section of pipe and a misaligned connection that had gone unnoticed. With this insight, the restaurant was able to make targeted repairs, eliminating the issue and avoiding further health code violations and business interruptions.
Grow with Confidence
Growth is exciting – but it’s also risky. The best way to manage that risk is to start with a clear understanding of what lies beneath. GPRS gives you that clarity. From utility locating to reality capture, from leak detection to digital mapping, GPRS lays the groundwork for safe, efficient, and scalable growth.
Before you break ground, make the call. Because when you build on a foundation of accurate data, there’s no limit to how high you can go.
