Utility Locating
No single geophysical instrument can be used to detect all underground utilities, NAEVA picks from their geophysical “toolbox” of complementary geophysical instruments to provide a complete on-site mark-out. NAEVA can accurately and precisely locate utilities employing a variety of instruments that primarily utilize the principles of electromagnetics (EM) and are designed to detect underground utilities constructed of electrically conductive materials. If EM methods will not detect a particular utility, GPR can be used to image the subsurface feature. Compared to typical “one-call” services, NAEVA offers the advantages of experienced scientists with a focus on complex commercial and industrial sites.
Detectable Utilities:
- Electric
- Natural Gas
- Telephone
- Fuel
- Water
- Sewer
Applications:
- Generate or update subsurface utility maps for future planned development
- Clear drilling location for subsurface interferences
- Identify utilities for avoidance during excavation
- Map utility pathways that may be related to contaminant migration
- Accurately mark-out utilities scheduled for repair or replacement
