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.

The goal of the GPRS Deliverables Department is to deliver clear and understandable findings with each of our outputs from field markings to field sketches, KMZ files, or CAD drawings that provide 2D site plans or even 3D CAD models. In addition, upon the completion of every project, our customers receive a job summary that includes job scope information, site photos, description of site conditions, equipment used, and notes from the project.

Rebar And Post Tension Locating – California

Ground Penetrating Radar Systems, LLC. (GPRS) of California was contacted by a general contractor to scan core drilling locations for plumbing and electrical at a hotel in East Bay area, CA. The contractor was not allowed to damage rebar during core drilling and especially did not want to drill through one of the numerous post tension cables that were embedded in the slab. 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. Unlike conventional X-Ray, GPR is not limited to a specific size of area at each location. We were able to scan at least a 2’ x 2’ area at each location so that the contractor would have safe options for drilling.
