Top 10 Questions for Underground Utility Locator Interview

1. How do you locate buried utilities using electromagnetic induction?

Sample Answer

• Electromagnetic induction locators (EMILs) generate a magnetic field that induces an electric current in the buried utility.
• The strength of the electric current varies depending on the size, material, and depth of the utility.
• The locator detects the electric current and produces a signal that indicates the location of the utility.

2. Describe the different types of underground utilities that you have experience locating.

Sample Answer

• Electric lines: These are the most common type of underground utility. They carry electricity from power plants to homes and businesses.
• Gas lines: These lines carry natural gas to homes and businesses. They are usually made of plastic or metal and are buried several feet underground.
• Water lines: These lines carry water from water treatment plants to homes and businesses. They are usually made of copper or plastic and are buried several feet underground.
• Sewer lines: These lines carry wastewater away from homes and businesses. They are usually made of concrete or plastic and are buried several feet underground.

3. What are the challenges of locating underground utilities in urban areas?

Sample Answer

• Densely populated areas: Underground utilities in urban areas are often located in close proximity to each other, making it difficult to identify and locate individual utilities.
• Underground obstacles: Underground obstacles such as rocks, concrete, and other utilities can interfere with the locator’s signal.
• Traffic and noise: Traffic and noise can make it difficult to concentrate and accurately locate utilities.

4. What are the safety precautions that you take when locating underground utilities?

Sample Answer

• Wear appropriate safety gear: This includes hard hat, safety glasses, gloves, and safety vest.
• Be aware of your surroundings: Pay attention to traffic, pedestrians, and other hazards.
• Use caution when digging: Only dig in areas that have been cleared by a utility locator.

5. How do you use GPS to mark the location of underground utilities?

Sample Answer

• Enable GPS on your locator: Most locators have built-in GPS functionality.
• Mark the location of the utility: Once you have located the utility, mark its location on the map using the locator’s GPS function.
• Export the data: You can export the GPS data to a file or share it with others.

6. How do you troubleshoot a locator that is not working properly?

Sample Answer

• Check the batteries: Make sure that the batteries are fresh and properly installed.
• Check the connections: Make sure that all of the connections are secure.
• Calibrate the locator: Most locators need to be calibrated periodically. Follow the manufacturer’s instructions for calibration.

7. What are the different types of locating equipment that you are familiar with?

Sample Answer

• Electromagnetic induction locators (EMILs): These are the most common type of locator. They generate a magnetic field that induces an electric current in the buried utility.
• Ground penetrating radar (GPR): GPR uses radar waves to create an image of the underground environment.
• Radio frequency locators: These locators use radio waves to locate buried utilities.

8. How do you stay up-to-date on the latest locating technology?

Sample Answer

• Attend industry conferences and workshops: Industry conferences and workshops are a great way to learn about the latest locating technology.
• Read industry publications: There are a number of industry publications that cover the latest locating technology.
• Talk to other locators: Other locators are a great source of information about the latest locating technology.

9. How do you handle situations where there are multiple utilities in close proximity?

Sample Answer

• Use different locating methods: Use different locating methods to help identify and locate each utility.
• Excavate carefully: Excavate carefully to avoid damaging any of the utilities.
• Work with other utilities: Work with other utilities to coordinate the excavation and repair process.

10. What is your experience with using GIS mapping software?

Sample Answer

• I have experience using GIS mapping software to create and manage maps of underground utilities.
• I can use GIS mapping software to identify and locate utilities, and to plan and coordinate excavation and repair work.
• I am familiar with the different GIS mapping software applications, and I am able to use them to create and manage maps of underground utilities.
