Welcome to GPRS, San José.

We Intelligently Visualize The Built World™ to help you reduce costs and change orders, save time, and keep everyone on your project safe.

    • Our comprehensive services include ground penetrating radar (GPR) and electromagnetic (EM) locating for post tension concrete imaging and subsurface utility locating, 3D laser scanning for millimeter-accurate measurements for any facility, acoustic leak detection and NASSCO certified video pipe (CCTV) inspection for facilities and municipal infrastructure, and drone imaging for orthomosiac aerial photogrammetry, all conducted by elite, SIM certified Project Managers.

    • Utility Locating: 60% of all utility lines are private, not public. 811 locates only public utilities, and does not provide depths for those locates. Our utility locating services employ both GPR and EM technology to provide a necessary and accurate supplement to One Call locates to provide utility mapping, and clearances for soil boring and direction drilling.
    • Concrete Scanning: Every GPRS concrete scan is backed by our exclusive Green Box Guarantee. Our accuracy rate for post tension concrete imaging is 99.8%+, so when we provide you with a green “clear” space to saw, cut, core, or drill, you know that you can count on our data when planning your project. If we get it wrong, we will pay for the cost of the damage.
    • 3D Laser Scanning: Our elite Project Managers employ survey-grade 3D LiDAR scanners to gather data that is accurate to within millimeters, and do it in far less time than manual measuring. The 3D point cloud data provided by the scans can then be utilized to create precise drawings, maps, and models to detect and avoid costly clashes and change orders, to allow for seamless off-site prefabrication, and as-builts that streamline everything from the design to O&M phase of your project.
    • Video Pipe Inspection: GPRS offers a comprehensive suite of video (CCTV) sewer inspection services, including sewer lateral inspections and mapping, to help you take control of your wastewater infrastructure. GPRS’ NASSCO-certified sewer video inspections capture every inch of your system - including the lateral lines - so you know what defects exist, the severity of those problems, and where exactly they’re located. You’ll receive a comprehensive, interactive report that includes video and photographs of the defects to give you a leg up on maintenance preparations. And we come to you – wherever you are. Our highly trained Project Managers are strategically stationed in every major market across the United States, so you always have qualified sewer inspection services near you and your jobsite.
    • Leak Detection: GPRS Project Managers employ both acoustic leak detectors (highly sensitive microphones, headsets, and electronic devices) and leak noise correlators (which use an algorithm to detect leak sounds) to gather data in the field. That data can then be used to provide the precise location of any pressurized water line leak, so that you can locate without the need to pothole and can excavate only in the area to be repaired.
    • Maps & Models: From the complimentary .KMZ & PDF files we provide for every outdoor utility locate to millimeter-accurate, complex 2D CAD drawings and 3D BIM models, GPRS’ Mapping & Modeling Team can deliver. We provide complete utility mapping, concrete image mapping, Matterport scanning, 3D point clouds, mesh models, and complete 3D BIM models and walkthrough tours so that everyone on your project has the most accurate, real-time information, delivered in an easy-to-use format for the entire project life cycle.
    • Drone Imagery: Our drones are fitted with state-of-the art cameras to provide UAS Thermographic and Magnetic Imagery to find previously hidden subsurface voids, damaged solar panels, and abandoned oil well heads. We also provide arial site imagery and building façade imagery to provide top-down facility mapping and avoid costly and time-consuming scaffolding inspections.
    • SiteMap: We can also provide you with the industry’s only comprehensive, top-down, facility infrastructure visualization & contextual map, all cross-referenced and delivered in a single, secure, shareable, and easy-to-use geospatial interface via SiteMap.

    GPRS Of Northern California Performs Concrete Scan – California

    GPRS Of Northern California Performs Concrete Scan – California

    Ground Penetrating Radar is a great tool to clear areas of utilities and conduits prior to core drilling or saw cutting. The concrete imaging process is entirely non destructive and free of radiation or health hazards.
    Rebar And Post Tension Locating – California

    Rebar And Post Tension Locating – California

    GPRS was able to locate and mark the upper and lower layers of rebar onto the surface of the concrete so that the core could be performed without cutting through post tension or rebar.
