What is the best procedure to follow when underground utilities may be present?

The most appropriate procedure when underground utilities may be present is to contact the local utility company. This action ensures that you receive accurate and up-to-date information about the location and specifications of underground utilities in the area where you plan to work. Utility companies have detailed records and maps that can help identify the presence of power lines, water pipes, gas lines, and other critical infrastructure.

By contacting them, you can arrange for a utility locate service, which will mark the locations of these utilities before any excavation begins. This is crucial for safety, as it helps prevent accidents, service interruptions, and costly damages associated with inadvertently hitting a buried utility line.

Other options do not provide the necessary steps to ensure safety and compliance with regulations regarding underground utilities. Ignoring the utilities can lead to dangerous situations and significant liabilities. Conducting a soil test does not provide information about the presence or location of utilities, and using a standard excavation plan may not take into account the specific conditions of the site, which could vary significantly depending on the existing utilities.
