Our last house had space, buried utilities, and a lot of buried irrigation pipe. Power went from garage to shed underground. That line also fed our mission-critical irrigation pump.
When the city brought in a fiber company, they used guided boring for installation.
They managed to knick the power line to the shed and I suspect at least 20% of every irrigation line in the neighborhood. The power line opened up a year later and I had to eat the replacement.
Net: try to make EVERY buried pipe, conduit, drain, and line traceable. The utility companies won't mark irrigation, nor anything they cannot detect. But you can. Don't save a nickel by using direct buried cable for anything. Run the conduit.
You WILL be digging/trenching/boring around your shop later...
