Did a survey in 1994, now I'm splitting off a tract in the northeast corner of it.
In 94 I wasn't using GPS, so the retracement is all TS(Topcon) vs. GPS(R10), NAD27 vs NAD83, SPC, both adjusted to surface.
Tieing in all the existing monuments (one missing for some unknown reason) there is very little disagreement between the 94 and the 16 survey, .03' is the large "misclosure", and that's across 1500'.
Except for two monuments, both about 0.25' off.
I'm not in the field for this and the PC tells me you can't "move" either cause the points are occupied by fence posts.
He says one is old and I must have set the monument along it, but I didn't, there wasn't a fence there then......
The other isn't one I need, it's at a new 8' tall privacy fence corner.......
If I hadn't been out there in 94 I wouldn't have known that the old fence is actually new, the land owner doesn't remember when it was built.
I always wanted to be on the range pole doing surveys, partly cause running the instrument is sooo boring, but mainly cause I wanted to see everything, glad I was when I did that survey.

Some of us get to say that about every survey!
Just last week I was searching for a corner where wrought iron fencing lines come together.
A nearby neighbor pulls in and from the signage on his truck and trailer, I can see he is a fencebuilder.
I inquire about his knowledge of his rear corner monuments, which he knows little about.
We have a discussion of fences built to the corners. He says much of their work is replacing existing fencing that is falling down. They cut the post off and set the auger over the old post stump and whirl away.
And would you not guess, he frequently finds a piece of rebar wound-up in the auger bit. He just puts the rebar back in the hole next to the new fence post and pours the concrete footer. He says that its within the general vicinity of the corner, because his bit is 1 foot wide, so the rebar is going back close to where it come from. And it's set in the concrete, so it ain't going anywhere for a while...
Then the real conversation began...
So, this type of practice by a fencebuilder could explain why a monument is off by up to half a foot near a fence.
sounds like the fence guy is practicing land surveying

a) Don't they (nearly) all do that?
b) Is there any good advice out there telling them what they should do? (Maybe from state PLS organizations?)
Did you correct the location of the two monuments?
or
Did your original location of the two monuments fall inside the corner posts?
I have been known to remove my monument when I know it has been moved this and other ways and to reset in original location.
When not possible to place in correct location I give a call to center of post and locate several witness (tree or other permanent type object).

Called it out now as an RM, can't really set the actual corner inside the post, so I'm calling it out referencing the monument with a tie.
The other corner isn't part of my survey, just located it in passing. it's up against the new post, anyone resurveying that one should be able to see the issue.

[SARCASM]Has anybody ever actually froze to death, way up North there where you live, while spending all day at the instrument ?[/SARCASM] 🙂

Just finished a survey where the gas company ran a new line along the highway right of way. They tore up the majority of corners along that side. Sad part is, most of the plats referencing the lots were written in cardinal directions. Those positions are lost forever now. Maybe we need a "Surveyor One Call Number".

My work consists of production housing and everyone wants one of those "beautiful" white plastic fences arount the back yard. The fence companies are always "concerned" (yea, right) when they dig up an iron rod at the corner. They do the same thing as you mentioned and re-set the corner where it looks like it should be. The furthest off I have found a corner is about 3 feet. Close enuff for fencing according to the fence companies.
Around here our corner monuments are usually a large wooden peg.
One of the better fencing companies is very careful to bore the corner posthole right where the peg is.
Then they nail the peg onto to the post.
