- I recently: Fd bent 3/4" conduit. I pulled it out, straightened it, which broke it. I drove both pieces down the on top of each other.?ÿ
Went home, did calcs. Concluded that the original marker was a 3/8" rebar. About 1/2' away. There were local witness objects. I wound up concluding that the 3/8 reb had been destroyed. And the conduit was just a marker set by a landowner, to help him not loose his corner. I set my rebar 1/2 ft from the conduit, and put the conduit back as a marker.
2.) Next job, there were some subdivision markers set in the c/l of an old dirt road. It had been chip and sealed 2x. I fd the 1/2" rebar 8" dp. In the road. Most had their tops bent over. I added either a 1/2" pipe, or 3/4" pipe, over the rebar to bring the monument to the surface. (After straightening) Then filled the hole with cool mix asphalt. About 20-30 minutes per monument. But they are rehabilitated.?ÿ I fd 1/2" pins on back corners, that were bent over. Obviously, other surveyors had been by there. I pulled these, straightened, and reset them. Everything fit record by less than a tenth. (A miracle!) But, the original surveyor did good work. And I found all needed corners.
Question: do you rehab markers, or leave them bent?
And, what is your logic?
Thanks!
Nate
I never have straightened out a found rebar or pipe. Just dug down enough to locate past the bent part. Was always told not to move or tamper with found monuments.
Yes, in my opinion it is a duty that goes with the privilege of being licensed.
Have rehabed many over the decades. Sometimes they are my own bars from years prior that have met abuse in some form.
Would have loved to have rehabed one last week, but, my current physical limitations prevented it. The rehab would have involved trying to carefully recover a 28" by 18" by 6" to 8" limestone found hanging in the rootball of a huge tree that had been knocked over, taking the stone set in 1882 with it. Fortunately, I had recovered that stone at the center of the section in a 1997 survey. Thus, I had precise dimensions to follow to set a bar and that came out dead center in the hole where the stone had spent close to 140 years.
only if the suveyor I'm working under directs me to do so, i will when Im licensed....its part of the process
Always had a 1/2" and 3/4" iron pipe in the truck as "pin straighteners". I wanted to put one in the auction for the state society fund raising event but thought it would cause toooooo much controversy.
Sometimes I do. Other times the old distressed monument becomes a memorial.
I haven't, no.
You and I know; the corner marked by a bent rebar, is the center of the hole it spins in, generally. Most of the general public hasn't got as clue.
Tie it out; straighten it up; put it back and make a note on your survey.
You're doing the general public a favor.
I was trained by a previous surveyor to note the direction of a bend, spin, pull, shoot the hole and put the bent pin back.
The guy I work for now has me do the same process but has me straighten out the bent monument before putting it back.
Bent or not anything is better than nothing
If I can identify the original location with certainty, it is my duty to rehabilitate the monument.
I will certainly straighten monuments, like radar said if you spin it, then it is easy to pull and fix it. In the case of Nate's story, when raising a monument, if possible I like to raise it with a like monument, so I keep short chunks of pipe to sleeve a deep iron, and then you can put a like iron inside to raise it to the surface. The original is still down there if someone wants it, and a like Iron is then near the surface.
Routinely. If I don’t, who will?
Just because I'm paranoid, doesn't mean they aren't out to get me.
I have a 3' piece of 3/4" galvanized pipe in the box. Used it the other day to straighten up a bent over #5 rebar. After straightening the rebar, my theoretical position hit the pin for less than a tenth.
yes, of course!
You and I know; the corner marked by a bent rebar, is the center of the hole it spins in, generally.
Is it though? I think that's a fine approach if you have a bar in some really stiff rock and it bends 90 which I have seen occasionally. I see this far more often though which, in my opinion, makes the original location much less clear.
Well, @bstrand I've been working at this for over 50 yrs. Generally, monuments get run over. I tend to think that the rehab puts the monument closer, than wherever the bent top happens to be that day.

I see this a lot, in Western Washington; lots of rocks and stones in the ground.
Some surveyors will drive the rebar in at an angle, instead of digging or drilling a hole.
I make a judgement, as to where to call the corner, on an individual case basis; after taking everything into consideration.
Anything is better than a Double Proportion...
It is (was) my policy that if I accepted the location marked by a substandard or damaged monument, it was replaced or rehabilitated to current state standard, which included a metallic cap with my PLS number on it. Being a recording state the found monument as well as the post survey monument was all of record.
