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.

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.
