What is Utility Locating?

Utility locating combines electromagnetic detection, ground-penetrating radar, and One-Call public utility marks into a single map of what's underground at a site. Hydrovac potholing is then used to physically verify critical lines at depth. Together, locating + potholing produces the SUE (Subsurface Utility Engineering) Quality Level A data that engineers and contractors need to design and dig safely.

Key Benefits in Washington

• Quality Level A SUE data for engineering, design, and construction
• Single-vendor coordination — locating + potholing in one mobilization
• Reduces utility strike incident rate to near zero on located sites
• Documentation suitable for damage prevention, permits, and as-built records
