Should a PS stamped survey be good for more than 6 months? 

Does this kind of thing happen often?

Should a PS stamped survey be good for more than 6 months?

6 months after receipt of a stamped survey, two crews from the same firm are in disagreement.

Only after you figure things can’t get any worse we get a second opinion from the same firm.

The department head, who didn’t even go out in the field, just stayed in the office and adjusted (red lined) the first stamped survey to his liking.

Now I will have 3 SE corner rods all within 10 inches of each other. Two placed by the same firm.  I told the second crew that before any rods get pulled I need a picture of all three.

Second survey now displaced no less than 5 lots that abut our east boundary and displace as many corner posts for said lots.

How much can change in six month that warrant a new survey?

What happens to the first survey that was delivered to the property owner?

Can an engineering firm just ask for the stamped sealed print back?

Background: This is all 6 lots (405 ft) away just starting the reference.

One right-of-way SW corner rod, of corner lot for address 303 which is 25’ ± off ¼ section line (center of road), was omitted off first survey, which necessitated a second visit, even thou the ¼ section line is still listed on first survey and in the same place as the second survey. (25’ from the ¼ section line)

The 1/4 section line didn’t move then why did the interpretation of the measurements change?

Our legal description uses ROW for both EW NS reference.

Legal description of 317 address uses a combination of ¼ section lines (EW) and ROW (NS) which is 25’ off center of road (NS) or ¼ section line (EW) both are the same.  Same holds true with the omission of a corner rod 25’ off a ¼ section line.  It all measures the same. 

Out of 6 lots to our west, 2 use the PK or center of road, 3 uses ROW, and 1 uses a combination of ROW and ¼ section line to define their property description.

Thanks in advance for comments and answers.
