Is that you can't see 1/4" through dirt.
So to know where things are, so you don't put holes in things that are down there, we call for line locates.
The utilities involved -who don't want their lines broken and have to fix them- come out and throw colored paint on the ground where the lines are:
Orange for COMM.
Red for ELECTRIC
Blue for WATER
Green for SEWER
Yellow for GAS
The way you're supposed to find them is to pothole where the paint is, to be sure the operator knows where they are.
That being said, the guys doing the potholing are supposed to stop when the FIND the utility they're looking for. That doesn't happen when you have three guys who give less than a f*ck.
I was told "Ya boss- that gas line is alor deeper than were digging."
Except that I know how deep gas lines are on this part of the base.
Except that I know the phone lines aren't encased in 'crete here, either.
We came on the orange sand about 2 feet below where they stopped.
Then we uncovered a second phone line that wasn't marked and called base comm guy -who didn't know it was there either.
Notice the way the pothole trench is going parallel with the marks instead of the more useful across the marking hole? If you go across where the line is supposed to be, you won't miss the gas line by 4" like we see in the last picture.
My spotter/co-operator asked why I didn't make them redo them. I told him I just wanted the stupid f*cks out of my way.
Their foreman didn't like it much when I called him out on it with the Super standing right on top of the most obvious miss (the top pic).
