Question: You are performing an excavation in Quebec. After receiving your locate request, the 'Info-Excavation' service provides you with a 'no utilities present' response for your specific excavation area. What is your obligation regarding further precautions before digging?
Answer options:
- You can proceed with full-depth mechanical excavation immediately. ✅ You must still conduct a visual inspection of the ground surface for signs of unrecorded utilities.
- You are required to hand-dig (hydro-vac or shovel) to the specified depth regardless of the 'no utilities' response.
- You only need to hand-dig if the soil type is rocky or difficult to penetrate.
Correct answer: You must still conduct a visual inspection of the ground surface for signs of unrecorded utilities.
Explanation: Even with a 'no utilities present' response from the locate service, it is a best practice and often a regulatory requirement to perform a visual inspection for signs of unrecorded utilities, such as old pavement cuts or surface features. This is an additional layer of diligence to prevent accidental strikes. Mechanical excavation can proceed with caution after visual inspection.
