A formal locate report or write-up should document the findings with: Utility Locating- The 70% Rule
: Before the locator arrives, the excavator should "white line" or pre-mark the planned work area with white paint or flags. This helps locators focus on the exact site, speeding up the process. locating
: This is the most common method. It involves a transmitter that sends a frequency down a conductive line and a receiver that detects the signal above ground. A formal locate report or write-up should document
: Active locating uses a transmitter to follow a specific route, while passive locating detects existing fields from live power lines. 3. Documentation and Marking It involves a transmitter that sends a frequency
In the context of construction and excavation, a is the process of identifying and marking the positions of underground utility lines—such as gas, electric, water, and telecommunications—to prevent damage during digging.
A standard write-up for a locating activity typically includes several critical components: 1. Pre-Excavation Steps
