PAUL, I AM NOT TALKING ABOUT BLUNDERS
Paul, you fail to understand what I am talking about. If you want to argue that it is unnecessary, then we have nothing to talk about. A single sideshot to property corner evidence does NOT provide a statistically independent measurement. A single side shot does provide a redundant measurement.
Juries are instructed to consider what is MORE LIKELY TO BE TRUE than not. So when a surveyor turns sets of angles and double ties property corner evidence and then examines that data via a least squares adjustment, can you imagine a jury concluding that the surveyor who used this process is mote likely to be able to report a more precise location than a surveyor who took a single rod shot? Substantial evidence is the basis of a sound professional opinion. A single side shot does not rise to the level of substantial evidence.
The issue is not what is good enough. The issue is not one of magnitude. The question is what provides sufficient grounds for the proper formation of a professional opinion.

Bad assumption Dane...sheesh..calm down

In the area I work in northern New Jersey and southern New York, due to the very rocky soil and ledge rock, it is common for rods and pipes to be set at an angle. The norm is to set and use the top of the cap as the corner. That is not to say that there are not exceptions, if the corner appears to have shifted due to the slope slumping I will locate the top, bottom and possibly even my best estimate of where the pipe may have been originally.

Because when you kick them they spin around like a top.

That's not what "Urban Dictionary" calls a "spinner" :-O
Dan, some areas here we have the same problem. Might start the pin at the intended position, but after it finds its way around rocks it ends up at a slant, driven to refusal and sticking up. Those conditions only allow for the top to be on and to get it in place might require bending. When retracing you need to consider the ground conditions and tie what seems to be the proper location. Note the slant and height of the monument in the notes. Spinning for location on monuments set in rocky ground may be the improper thing to do.

Well, there's not much urban about northern New Hampshire.
> I usually find it easier to set a tripod/tribrach and target over it rather than a prism pole.
I like to set the instrument up over the leaning pipe. But it's very important to get the vertical axis of the instrument set to precisely the same angle as the pipe. This way, your laser plummet can shoot all the way to the bottom of the pipe. I tried for hours hanging a plumb bob down, but I could never get it to hang at the same angle as the pipe. Go figure.

Dane,
I agree and turn multi-sets d & r to corners, BUT it takes a very good Attorney to explane that to the jury.
