UTILITY LOCATING

Private utility locating is vital to any construction, excavation, or renovation project. 811 One Call services locate public utility lines, but do not provide depths for them. Nor do they detect or locate private utilities. Our private utility locating services employ Ground Penetrating Radar (GPR), Electromagnetic locators, CCTV Video Cameras, Acoustic leak locators and other equipment to scan for subsurface utilities, including depths and GPS mapping, saving time, money, and even lives by avoiding utility strikes to protect & all site employees and contractors from potential line strike damages. GPRS provides complimentary .KMZ files for all of our exterior utility locating projects.

VIDEO PIPE INSPECTION

The majority of pipe defects occur underground in buried pipe that can only be accessed by excavation or CCTV cameras via a Video Pipe Inspection (VPI). GPRS deploys both robotic crawler CCTV cameras and lateral launch cameras and push cameras to document and assess water systems, drains, and conduct sewer inspections without costly excavation. Our NASSCO certified WinCan VPI reports provide clients the exact location, photo, video, and map of each defect, cross-referenced and tagged with a defect severity level. This allows our clients to visualize every inch of water and sewer pipe with in their system and to create comprehensive repair and maintenance plans to repair pipe damage in the most cost-effective manner possible.

CONCRETE SCANNING

Any project involving post-tension or slab-on-grade concrete contains an inherent risk of costly damage and/or injury when you core or cut into the slab. Rebar, conduit, and post-tension cables pose significant strike risks, and each has its own unique GPR imaging signature. GPRS’ concrete scanning service provides digital concrete scanning with ground penetrating radar (GPR) to accurately pinpoint the location of each hazard and map it in detail, so there is never a question of where you can cut and where you can’t. Unlike concrete x-ray services, GPR concrete imaging does not require you to close off sections of your site to avoid radiation. In most cases, your work can continue while we scan and locate slab reinforcement and conduits with 99.8%+ accuracy, so that you can safely cut and drill.

What is ground penetrating radar?

You cannot avoid what you cannot see. Ground Penetrating Radar (GPR) is anon-invasive locating tool that allows our SIM Certified Project Managers to scan post-tension concrete for conduit, rebar, and other encased objects, and to effectively locate utility lines, water and sewer pipes, telecom and fiberoptic cables, and subsurface voids.

GPR functions by sending radar signals into a surface like concrete or soil and capturing that signal as it bounces back to create a specific reading that allows our highly trained Project Managers to determine the length, depth, and type of subsurface feature located.

The various location features can then be marked out on the surface to show the precise location and provide clear boundaries and spaces where you can cut, drill, or excavate safely. GPRS takes our GPR subsurface locates farther by providing GPS mapping, and we can provide a variety of images, maps, and models to Intelligently Visualize The Built World, above and below ground.

COSTLY MISTAKES DO NOT NEED TO BE ROUTINE

According to a 2022 report in Digital Builder, 69% of projects in the last three years were 10% or more over budget.

Which means only 31% of projects came in almost on budget – within 10% of their original estimates.

The 2021 GPRS Market Study by Finch found that 78% of facility managers reported damage due to a locating issue, with an average cost of $56,000 and two-to-three months of project delay per event.
And global consulting firm, McKinsey & Company, reports that across all industry areas, 80% of construction projects finish over budget and suggests the #1 way to disrupt this troubling trend is to execute rapid digital mapping for greater accuracy and more immediate results.

The industry is so used to poor locates, as-builts, and communications that most have built these huge cost overruns into their budgets as routine.

Costly and potentially dangerous mistakes do not need to be routine.

It is impossible to execute a great plan on time and on budget if it is built on incomplete or incorrect data.

It is possible to greatly reduce or even eliminate cost overruns when you have accurate data delivered in easy-to-understand formats before you execute your project.
"Thank you for the 3D Model. You found all of the parts we were looking for with great accuracy. We were very pleased to see you found the “X” brace and the gas pipe under the feeder in your scan images."
- Brian B. - Technical Lead - R&D
3D laser scanning allows you to capture complete as-builts in a fraction of the time of hand measuring, with 2-4 mm accuracy.

GPRS TruePoint Laser Scanning was a great partner to The Virginia Air and Space Science Center. The team at TruePoint was open and honest about the pricing and process. I was even happier when I heard they were able to meet an already tight deadline and budget. TruePoint had a quick turnaround on deliverables that saved time within the project. We look forward to working with them on future projects.
- Michael T. – Director Of Facilities, The Virginia Air And Space Science Center
You did a great job! The Revit model was very useful, it gave us a great starting point to build our design model. The fly-through was just as helpful. Doing a normal field investigation you never seem to get the picture you need. With the fly-through, I can get any angle needed -- not to mention -- having it during a meeting when something comes up clients want to see. We have used other scanning firms for smaller scale projects and haven’t had the same results. You guys were very professional and met every deliverable that was promised, even on the tight schedule. If and when we are doing a project of this scale we will keep you mind.
- Bradford S. – Mechanical Designer
Thanks for jumping into this assignment so quickly. What a great and productive trip. You guys work tirelessly, non-stop with all aspects of the setup and execution. Your ability to master the technology is a game changer for us.

HOW THE TECHNOLOGY WORKS
3D laser scanners use LiDAR (light detection and ranging) to measure and record precise locations and distances, ultimately producing a point cloud file.

The primary way a laser scanner works is to send light pulses at high speed which reflect off objects and return to the scanner’s sensor (LiDAR). For each pulse, the distance between the scanner and object is measured by determining the elapsed time between the sent and received pulses. Each data point is converted to a pixel with a known x, y, and z coordinate.

Millions of data points from multiple positions and viewpoints are captured and processed into a point cloud, creating an accurate 3D as-built data set of the site. This all happens very quickly, with some scanners, like our Leica RTC360, capturing and calculating 2 million points per second with 2-4 mm accuracy.

While the applications of LiDAR and laser scanning are almost limitless, there are specific formats that allow our design team to deliver customized solutions for your needs.
