Why should utilities be "potholed" before using a boring machine?

• A. For quicker excavation
• B. To prevent damage to machinery
• C. For visual verification
• D. To minimize costs

Answer: (C)

Utilities should be "potholed" before using a boring machine primarily for visual verification. This practice involves digging a small hole to expose underground utilities, allowing operators to accurately identify their location and depth. By confirming the presence and placement of these utilities, the risk of accidental strikes during the boring process is significantly reduced. Understanding the exact layout of existing utilities is crucial because it helps ensure safety, protects expensive equipment, and minimizes the potential for service interruptions.

While quick excavation, prevention of damage to machinery, and cost minimization might be additional benefits of this practice, the key reason for potholing is to ensure that operators can visually confirm the utilities they will be working near. The importance of visual verification cannot be overstated in excavation and boring tasks, as it ultimately supports safer and more efficient project execution.
