Services
Utility Locating
Our utility locating service identifies underground infrastructure with 99.8% accuracy using ground penetrating radar and electromagnetic locators. We map public and private utilities including water, sewer, electrical, and communication lines. Deliverables include georeferenced digital maps and SiteMap platform integration for construction planning and excavation safety.
Concrete Scanning
Concrete scanning uses GPR technology to detect rebar, post-tension cables, and conduits in structural slabs. Our non-destructive testing identifies hazards before coring or cutting operations. The Green Box Guarantee ensures 99.8% accuracy for commercial and industrial applications while maintaining active worksite safety.
3D Laser Scanning
3D laser scanning creates millimeter-accurate digital twins of facilities and infrastructure. We use Leica scanners and Matterport technology to generate BIM models, as-built drawings, and virtual tours. Deliverables support MEP coordination, clash detection, and facility management across architecture and engineering projects.
Video Pipe Inspection
NASSCO-certified video pipe inspections use robotic crawlers and lateral launch cameras to assess sewer infrastructure. We identify cross bores, structural defects, and blockages while generating interactive WinCan reports. Our defect mapping integrates with utility data for comprehensive subsurface visualization.
Leak Detection
Acoustic leak detection services identify pressurized water line failures using specialized microphones and correlators. We combine leak detection with CCTV inspections and utility locating to prevent water loss. Our subsurface investigation methodology achieves 99.8% accuracy in municipal and industrial water infrastructure assessments.
Questions
How does GPRS locate utilities?
GPRS uses SIM Subsurface Investigation Methodology combining ground penetrating radar, electromagnetic locators, and RTK positioning to achieve 99.8% accuracy in utility mapping.
What tools are used for utility locating?
We employ ground penetrating radar (GPR) for non-conductive materials, electromagnetic locators for conductive lines, and radio frequency transmitters as part of our comprehensive SIM process.
Why supplement 811 utility locates?
811 services only mark public utilities. GPRS locates private and unregistered utilities missing from 811 data to prevent costly subsurface damage.
What happens if a utility line is struck?
Utility strikes risk serious injury, service disruptions, environmental hazards, and legal liability. Our 99.8% accurate locating prevents these incidents.
What is NASSCO certification?
NASSCO PACP, LACP, and MACP certifications ensure standardized defect coding and reporting for sewer infrastructure assessments using video pipe inspection technology.
