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 provide inspections for private utilities. Our private utility locating services employ Ground Penetrating Radar (GPR), Electromagnetic 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 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 push cameras to document and assess water systems, drains, and conduct sewer inspections without costly excavation. Our NASSCO certified 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 pipe with in their system and to create comprehensive repair and maintenance plans to repair damage in the most cost-effective manner possible.

CONCRETE SCANNING

Any project involving post-tension 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 utility inspections do not require you to close off sections of your site to avoid radiation. In most cases, your work can continue while we scan and mark out your slab with 99.8%+ accuracy, so that you can safely cut and drill.

3D Laser scanning

The #1 way to avoid costly change orders, clashes, and downtime in the construction and renovation planning, is to hire a professional 3D laser scanning company to execute accurate digital maps of as-built conditions to provide drawings, maps, models, and even a true digital twin.

GPRS 3D Laser Scanning Services eliminate time-consuming manual measurements by capturing as-builts with millimeter accuracy at up to two million data points per second to create point clouds, maps, CAD drawings, and 3D BIM models for the engineering, design, construction, architectural, oil & gas, facility, management, multimedia, historical preservation, education, healthcare, water, energy, and utility industries.

3D laser scanners utilize LiDAR (light detection and ranging) to assess any location with 2-4 mm precision, so you can confidently execute your vision in days instead of weeks or months, while further reducing inaccuracies, mistakes, and costs.

We utilize the most responsive software to provide a wide. variety of maps and models, and even 3D walkthrough tours of your site.

MAPPING AND MODELING

Complete facility visualization is impossible without accurate documentation. That’s why GPRS provides complimentary high-resolution maps in the form of PDF, KMZ, and SHP files with every outdoor utility locating project we perform.

‍We offer fully integrated reality capture with 3D laser scanning, concrete scanning, outdoor and interior utility locating, Video PipeInspection via CCTV, and drone imagery to provide point clouds, 2D & 3D CAD drawings, 3D BIM models, 3D mesh models, photogrammetry, and customized 3D BIM model walkthroughs, depending on our clients’ needs.

We are the only company able to provide complete top-down imaging, mapping, and modeling of any facility, above and below ground to fully Visualize The Built World™ for our clients nationwide.

Leak Detection

GPRS Leak Detection Services can quickly pinpoint a known leak when a problem is identified in municipal water or sewer infrastructure or for an industrial facility. We can proactively search for leaks in domestic water and fire systems, and complete Water Loss Surveys to locate problems before they are evident and costly.

Acoustic leak detection is aided by leak correlation to provide accurate, real-time verification of an active breach and can be integrated with our Video Pipe Inspection Services and utility locating to improve commercial, industrial, and municipal water infrastructure efficiency, and avoid unnecessary excavation.
