Question: When planning to bore under an existing water main, what critical information must be obtained and considered for the crossing procedure, beyond just the locate mark?

Answer options:

• The colour of the water main pipe ✅ The current water pressure, material composition, age, and exact depth/width of the water main
• The date of the last repair on the water main
• The identity of the original installer of the water main

Correct answer: The current water pressure, material composition, age, and exact depth/width of the water main

Explanation: A complete crossing procedure requires comprehensive information about the existing utility, including its exact dimensions, material, age, condition, and operational specifics like pressure, to ensure the boring operation does not compromise its integrity, as highlighted by CCOHS guidelines for working near utilities.
