How many hours in advance must utility companies be contacted to locate underground installations before digging?

Utility companies must be contacted to locate underground installations at least 48 hours in advance before any digging takes place. This requirement is in place to ensure the safety of construction projects and to prevent accidents, such as hitting gas, water, or electrical lines. By allowing this time frame, utility companies can effectively mark the locations of their underground facilities to prevent damage and ensure the safety of workers and the public. This standard timeframe is commonly practiced across various jurisdictions, emphasizing the importance of careful planning and communication in digging operations.
