What Happens During a Utility Locate?

A utility locate is a field process used to identify the approximate path of buried infrastructure. The goal is to provide clear markings and documentation so excavation can proceed safely and predictably.

Step 1: Understanding the Scope

Locating starts with context: ticket details, site access, known utility types, and any available records or constraints. A good locate is not “one size fits all.”

Step 2: Locating Methods

Most locating relies on electromagnetic methods. Depending on the situation, a locator may use:

• Direct connect (best accuracy when access allows)
• Induction (useful when direct connection isn’t possible)
• Passive locating (power/communications signals where applicable)

Each method has limitations. Strong locating relies on choosing the correct method, not just rushing to mark and move on.

Step 3: Marking & Documentation

Markings should be clear, consistent, and tied to the actual signal path. Where visibility is limited or conditions are complex, documentation and communication become just as important as paint and flags.

What a Locate Does and Doesn’t Guarantee

Locates identify an approximate path based on detectable signals. Not all utilities are traceable, and not all sites have complete records. When the risk is high or uncertainty is unacceptable, additional verification may be required (private locating, hydro-excavation, or coordinated verification).

The difference between a routine locate and a professional one is simple: taking the time to verify what’s real on site instead of assuming.
