Rebar

I've known some who use rebar for GPS control.?ÿ I've found it within 10' of a corner.?ÿ Fine while the plastic cap is intact, but it'll cause some confusion after it's mauled or gone

48" Hi-lift jack works great for plucking those suckers.?ÿ

I routinely use capped rebar for control points. And so do lots of other people around here. Oregon law calls for 5/8" rebar as property corners, I use 1/2" for my control/traverse points.?ÿ

Vice grips for pulling bars. Once you get the bar turned 1 or 2 rotations it usually slips out easily after that.?ÿ But I can't remember ever pulling someone else's bar.

@williwaw?ÿ

I hit it with the 6 pounder a couple of times, grabbed it with the pliers and yanked it out. It was a long one too, 30". Not sure what was going on with it, it may have been a 1991 era survey, but I match that guy within a few tenths every time, of course I always accept him. Maybe it was an old control point. Difficult to know but it's too close to the corner position to leave it there.?ÿ

@mightymoe I can count on one hand the number I've pulled in 20 years but usually same situation. One engineering firm around here was using them for random traverse points and paid little attention to setting them in close proximity to legitimate corners. Once the caps came off they were a hazard and had thrown me for a loop and cost me significant time more than once. I called them on it but they didn't care since the headaches they created were not theirs.?ÿ

Back in the 60's when I worked for the power company, they had a contract survey crew stake a bunch of lake lots and they made a mistake setting the irons and we had to pull a bunch of them up.?ÿ We had a washer welded to a chain and the chain welded to a bumper jack, all we had to do was slip the washer over the rebar and the friction was able to pull the rebar.?ÿ

@ekillo?ÿ

I learned some time ago while staking property lines not to leave a control point near line. Either put them on line, have them way off somewhere, or hide them if you have to have them close.?ÿ

I love you, man, but please don't do that.....if you ever happen to work in New England

Well, OR is a recording state, and a random rebar with no reference and no cap is just a random rebar.?ÿ

What Norman describes is pretty standard. I have had to admonish some of my coworkers to take care when setting control points close to the line. I usually tell them to drive them below grade. If a surveyor finds them, and have my survey, they should be good. If a home owner finds them...who knows.

If I didn't work in a recording state I suppose I might have to re-examine the practice. But here it's not a big problem.?ÿ And like I said, I'm not the only one doing it.?ÿ

Or were you talking about twisting irons out of the ground??ÿ

Almost all the rebar control points I have seen have a cap stamped ƒ??Control Point.ƒ?

Pipe wrench works well for pulling.

45 years in and never felt it necessary to pull someone iron up. Cussed, spit and kicked a few, but who am I??ÿ Why not pull up the one's 3 feet off or even 0.2 feet away??ÿ

@oldpacer?ÿ

One corner, one monument. The client doesn't need a bunch of junk around his corner.

We pulled 4 on one lot corner earlier this summer, only one of them was of record and the surveyor asked us to remove it, what the others were is speculation as none of them were the original pipes and none of them made any sense (possibly some rebar for fence tie downs). The one I pulled Monday was probably a surveyor I followed in the area, but he is long gone and no one ever used or even saw his monument. He didn't record anything so......

@williwaw Please explain.?ÿ I've been punished lately by trying to replace a couple of bent rods that turned out to be s-shaped and longer than normal.?ÿ I've got a high lift, is there a special attachment or did you fab something??ÿ My lower back will thank you!

@mark-indzeris You just need a few feet of chain with links large enough to slip over the rebar, hook the other end over the foot of the jack and start cranking. They pull with the same force they lift. I have a 12ƒ?? tow chain I use. Works slick.

@williwaw Thanks.?ÿ On my way to the hardware store now to get some chain.?ÿ The rod man is gonna hate toting the high lift around ???? . ?ÿ Good thing it's rare that I'll need to use it.?ÿ

@dmyhill except for the 100 or so years between GLO and recording..?ÿ

Pulled a rebar yesterday. It was about 10 feet from the corner math position and there is no history for it since my client is giving up his occupation of the land. Don't do very often, but sometimes you gotta get the channel locks out.?ÿ

I hope that one day I'm that sure of my determination that I can do that.?ÿ

If you don't mind me asking, what other variables did you consider when making this decision??ÿ How large was the parcel, how long was the boundary line, and when was the survey originally done??ÿ Was it originally run with chain and compass or is it a much newer survey??ÿ Was there a monument called for at that corner at all??ÿ How do you know it isn't a monument for an easement on the neighbor's property or something like that??ÿ Do you need to research the adjoiner's parcel to decide that??ÿ In many states unrecorded surveys and documents are valid.?ÿ In your state do unrecorded documents hold any weight??ÿ

Obviously, I need to consider my own state laws and court cases, local practice, etc.?ÿ But I am just curious and interested in hearing more.

I am no expert, which is why I am asking.

Thank you
