“You gotta be kidding...engineers still learning about underground utilities etc...????”
Old buried utility lines are seldom accurately mapped.
A cousin once worked for an engineering company that searched for underground utilities before road projects began. She said that they normally performed the searches in the very early stages of a project, as part of the project planning.
She also said that it was amazing how many things went under roads that nobody knew about.
I can definitely attest to that.
What makes it tough, they can’t/don’t locate abandoned utilities
Makes ones heart jump like when an unexpected phone line comes up with a bucket of dirt
