Accuracy of Control
Posted by imaudigger on February 23, 2017 at 5:12 pmI think my accuracy was pretty good. .09′ is within the 10 ring.
The TV cable is buried….Control point is a randomly placed #5 x 18″ long rebar.

You must be a killer at darts.

Did you sever the TV cable? It doesn’t count unless you actually do some damage.

Nope – thankfully didn’t hit it.
I had called USA prior so I would have been covered. The TV cable company was delayed in actually marking their utilities. It would have been them learning a lesson – not me. -
How are you getting USA to locate for you? Are you marking your control locations individually? I’ve given up with the pre-design requests since they started getting nasty with me over the size of my located requests.

I mark the beginning and end of the project and tell them I will be doing excavation work. Not very many buried utilities in most of the places we do projects, so they have not complained yet. I’ll get a backhoe out there to dig a hole if they really think that’s what it takes to mark their utilities.

If you are surveying a larger project, call in multiple tickets. I usually go no longer than 300 ft linear in a street topo in small town America where I live. Then I call in the next ticket. The locate contractors get paid per ticket so this pleases them. Also always say you are driving rebar deep, when they ask where tell em “I don’t know until you mark”
