Utility Locating: What You Can’t See Can Hurt Your Project
Subsurface utility locating isn’t just a routine box to check before excavation - it’s a key risk management step that can protect your team, avoid costly damage and keep your project on track. From gas lines to fiber optics to abandoned infrastructure, what lies underground is often more complicated than what shows up on the drawings.
At OmniVueNDT, we help clients take the guesswork out of subsurface mapping. Our utility locating services combine multiple non-destructive technologies, including Ground Penetrating Radar (GPR), electromagnetic locators (EML), metal detectors and traceable sondes, to deliver a comprehensive and accurate understanding of what’s below.
Why It Matters
In urban infill and redevelopment projects, contractors often face unexpected utility conflicts. That’s especially true when existing records are incomplete, outdated or simply wrong. Striking an unmarked water main or communication line can lead to project shutdowns, legal claims or life-threatening conditions.
Even on new construction sites, underground utility conflicts can delay foundation pours, increase permitting timelines and trigger expensive redesigns. Knowing what’s beneath the surface helps you plan smarter - and avoid surprises later.
Layered Detection for Clearer Results
Our process starts with electromagnetic locating to trace conductive utilities such as electrical lines, water pipes or tracer-wired systems. For non-conductive materials like PVC or empty conduits, we use high-frequency GPR to identify changes in subsurface composition. If needed, we deploy sondes to trace unknown line paths and confirm utility terminations.
Each site is different, which is why our technicians adapt the strategy based on soil type, target depth and site layout. We scan multiple grids, cross-reference findings and provide clear markings and digital documentation to guide your team’s next steps.
Project Example: Industrial Site Redevelopment
A recent client engaged us for a large-scale warehouse redevelopment on a former industrial site. As-built documentation was limited and unreliable. Our team conducted a full utility survey across 7 acres, locating gas, telecom, water and legacy oil lines, as well as two undocumented concrete vaults. Based on our findings, the design team rerouted their utility plan, which not only prevented excavation delays but eliminated the need for costly remediation after construction began.
Build With Confidence
Utility locating is more than due diligence - it’s a strategic move to protect your people and your budget. Whether you're prepping for excavation, trenching or site redesign, OmniVueNDT brings the clarity you need to move forward with confidence.
