Los Angeles, California Utility Locating, Concrete Scanning, 3D Laser Scanning, Video Pipe Inspection, Leak Detection Services

GPRS offers a full suite of services, including ground penetrating radar (GPR) and electromagnetic (EM) locating for subsurface utility locating and concrete scanning, 3D laser scanning for millimeter‑accurate building measurements, acoustic leak detection, and NASSCO‑certified video pipe (CCTV) inspection for water and sewer infrastructure, all verified and delivered by our elite, SIM-certified Project Managers.

Utility Locating: GPRS utility locating maps subsurface utilities to minimize risk and delays. 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: Concrete scanning locates rebar, post tension cables, electrical conduits, and potential voids, before cutting or coring. 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 2D CAD drawings and 3D BIM models that integrate directly into your design software, streamlining workflows and reducing costly errors.
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 WinCan report that includes video and photographs of the defects to give you a leg up on maintenance preparations.
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 with every outdoor utility locate to millimeter-accurate 2D CAD drawings and 3D BIM models, the GPRS’ Mapping & Modeling Team delivers precision. Our services include CAD utility maps, concrete image mapping, 3D point clouds, 2D CAD files, floorplans, BOMA measurements, 3D mesh models, 3D Revit models, virtual tours, and more, so that everyone on your project team has the most accurate, real-time information, delivered in an easy-to-use format throughout the project life cycle.
Ground Penetrating Radar (GPR): Ground penetrating radar services give architects, engineers, contractors, and facility managers a clear view of what lies beneath the surface before construction begins. Our SIM-certified Project Managers deliver precise utility locating, concrete scanning, slab thickness measurement, rebar and conduit mapping, and facility documentation, helping you avoid costly mistakes during cutting, coring, or excavation. Because GPR is non-destructive, you gain detailed insights without damaging structures or disrupting operations, all while keeping safety at the forefront. With GPRS, you get the reliable data needed to reduce risk, streamline collaboration, and keep projects on track.
SiteMap: SiteMap is GPRS' powerful GIS software platform that delivers digital above and below-ground as-builts, including customized utility maps, point clouds, CAD drawings, BIM models, NASSCO-certified inspection reports, and more. All data is secure, shareable, and accessible 24/7.
