Subsurface Damage Prevention

BEFORE YOU BUILD, CUT, CORE, OR DIG, CALL GPRS

When it comes to construction and facility management, every decision you make can cost time, money, and even lives. GPRS is in pursuit of a world with 100% subsurface damage prevention. Our 99.8% accuracy rate for ground penetrating radar services (GPR), utility locating services, utility mapping services, and concrete scanning services will locate critical targets like underground utilities, post tension cables, rebar, conduits, underground storage tanks (USTs), and more to help keep your project on time, on budget, and safe. Our NASSCO-certified CCTV video pipe inspection & leak detection services find pipe defects, blockages, and leaks with pinpoint accuracy.

Existing Conditions Documentation

ACCESS ACCURATE AS-BUILTS WITH OUR INFRASTRUCTURE MAPPING & MODELING SERVICES

When record drawings do not match the as-built conditions, general contractors and facility managers are at risk of avoidable change orders, delays, budget overruns, and even damage or injuries. Let GPRS’ in-house team create an as-built (TruBuilt) for your project – showing actual existing conditions above or below ground… or both. Our 3D Laser Scanning, reality capture services, and 3D Photogrammetry services deliver up-to-date and accurate construction as-builts, existing condition drawings, 2D CAD drawings, 3D BIM models, 3D mesh models, digital twins, point clouds, updated floorplans (FLRPLN), Reflected Ceiling Plans (RCP) and more for construction design, prefabrication, clash detection, facility modifications, and asset management.

Ground Penetrating RadaR (GPR)

Ground penetrating radar (GPR) is a non-destructive geophysical technique utilized in construction to analyze the subsurface conditions of a given site. By emitting electromagnetic pulses into the ground and capturing the reflected signals, GPR generates a visual representation of subsurface features. In construction applications, GPR serves multiple functions such as utility mapping, concrete imaging, quality assurance, and environmental assessment. It facilitates the detection of underground utilities like pipes, cables, and conduits, aiding in pre-construction planning and excavation safety. Additionally, GPR can pinpoint the presence and positioning of reinforcement bars (rebar) or post-tension cables within concrete slabs, ensuring structural integrity. Ground Penetrating Radar's ability to deliver real-time subsurface insights without causing damage makes it indispensable, enhancing safety, efficiency, and cost-effectiveness throughout construction projects.

UTILITY LOCATING Services

Private utility locating is vital to any construction, excavation, or renovation project. 811 One Call services locate public utility lines, but do not typically locate private utilities. GPRS is private utility locating company that employs Ground Penetrating Radar (GPR), electromagnetic locators, CCTV video cameras, acoustic water 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. Our utility mapping services can create an updated as-built drawing for your campus or facility. GPR services can also be used to locate underground storage tanks (USTs), unknown utilities, and even manholes and well heads.

Illustration of Subsurface Pipeline Locating

cctv VIDEO PIPE INSPECTION

The majority of sewer pipe defects occur underground in buried pipes that can only be accessed by excavation or CCTV cameras via a Video Pipe Inspection (VPI). GPRS deploys both robotic crawler CCTV pipe cameras and lateral launch cameras to document and assess water systems, drains, and conduct sewer camera inspection services without costly excavation. Our NASSCO-certified WinCan video pipeline inspection reports provide clients the exact location and map of each defect, cross-referenced and tagged with a defect severity level. A CCTV sewer pipe inspection service allows our clients to visualize every inch of water and sewer pipe within 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.
