To ensure the overall timely success of you project, utility detection is critical to any construction project where a subsurface excavation is planned. If this critical first step is ignored, the risk for injury increases, budget overruns can multiply and your schedule can be delayed.

Video Pipe Inspection (CCTV) is a service used to inspect underground water sewer and lateral pipelines, VPI is a great tool for investigating cross-bores, structural faults and damages, and lateral line inspection.

With new build construction and renovation project, the likelihood of needing to cut or core concrete is high. There is an inherent risk of striking rebar, conduits, and post tension cables during the cutting or coring process. If a strict occurs, repair costs begin to add up, delays creep into your schedule and it creates a safety hazard for your employees.

Utility Locating Prior To Installing Solar Panels – California

Utilizing the latest in Ground Penetrating Radar (GPR) technology and Radio Detection, Greg Milburn of the GPRS San Francisco/Oakland office, responded to the site and was able to mark out various utilities traveling through the proposed excavation area. Scans were taken with the GSSI 400mhz antenna, combined with the RD7000 radio detection device to search for electric, gas, communication, water, sewer and unknown lines. GPRS findings were then marked directly onto the surface in real time for the customer to see. By utilizing GPRS, the customer was able to identify underground utilities and other subsurface obstructions in the area in a nondestructive, safe manner. The use of the professional services provided by GPRS allowed the customer to excavate promptly and safely, while keeping their project on schedule.
