I was in my cubicle the other day putting some finishing touches on a topo when I heard one of our construction inspectors saying, "Yeah, the contractor is starting that conduit jacking job over on XXX Street tomorrow."
I jumped up and asked him," Whoa, what are they doing out there, and where? There is a quarter corner AND a DLC corner down there, right in the proposed path of the conduit!"
Long story short, I ran out there with the inspector, met with the super, flagged up those mons real well, and the proposed path was changed to be a good distance away from the mons. Yay.
Sometimes you're not so lucky
I had an inspector bring me in a USGS benchmark disc that had been in the footing of an elevated water tank. The footings were being replaced and he thought I would like it as a souvenir. That's nice but I sure wish I had known ahead of time so it could have been relocated (that was back in the days that USGS would relocate monuments).

Sometimes you're not so lucky
Heh. One time many moons ago, I had a contractor bring me a chunk of concrete with a brass disc and said, "I saved it for you." It had been all flagged up with ribbon and lath marked SAVE and SURVEY MONUMENT, and should have been safe from disturbance. Some overzealous cat operator wiped it out. :-@

Sometimes you're not so lucky
We're pretty lucky in that we now have all our Designers, Construction crews and even Engineers looking out for our PSMs. Avoiding if possible but giving us plenty of heads up should they require to disturb them.
Special Provision regarding survey monumentation
Zapper-
Here's a link to a Special Provision regarding survey monumentation that I worked on persuading OGRA to adopt such a protocol.
http://www.ogra.org/Portals/0/Special%20Provision%20Survey%20Monumentation.pdf
OGRA staff engineer wrote a very good first draft and then it was subsequently amended with input from practicing surveyors (as it is a 'living' document)
Please feel free to adapt the SP to your areas.
Cheers,
Derek
:good: Good job.
I was out looking for a section corner once in the middle of a street intersection in Denver. There were a lot of monument ties on the curb, and a huge (I don't know 15' X 15' area of new asphalt in the middle of the intersection. I felt pretty certain I wouldn't find anything but felt it was my due diligence to dig. I was out in the middle of the intersection with a gas-powered jack hammer and digging tools and some guy came up to the intersection in his pickup truck and rolled down the window. He asked me what I was looking for and I told him. He said "you ain't gonna find it. I won't tell you how I know but I'll guarantee you it's gone". I dug my hole and filled it up and came back later and set a monument by the ties. I guess he didn't really have to tell me.
Thanks!
Thanks, Brad, but . . . :whistle: Atta :girl: 🙂

I was afraid of that. So sorry.
I've heard more than one story about how a good intentioned land owner or contractor moved a bench mark or property corner to a better location so it would be out of the way.
South Louisiana is a severe subsidence zone. One particular Class "A" sleeved benchmark started protruding above the aluminum casing ... the grass cutters thoughtfully hacksawed the top off so that it would not be damaged by their lawnmowers.

Thanks!
No worries! 🙂
