Is that an acceptable monument for a recorded map or survey by any County Surveyor? ?ÿ
There's one similar to that a few blocks from me, but instead of a mag nail the tag is epoxied to a paver.?ÿ The "monument" is shown on a Corner Record.?ÿ
Whenever a utility comes along to dig things up that paver is likely to end up in a different location.?ÿ ?ÿ I complained to the regional JPPC about it, but nothing was done.
And, for a mea culpa...when I was new at this, I set a lead and tack in the top of a keystone wall. Now, the capstone was glued down with mastic, but it did move when they tore down the wall and rebuilt it...oops.
Well, it is a working point and not record map monument, right?

Just curious.

Yes, for many up here as it is defined by Act in Ontario.?ÿ They are usually set with a washer stating "OLS ####" with the # being their registered number.?ÿ One would pound the concrete pin and washer flush or below the adjacent grade if possible to avoid snow plows ripping it out.?ÿ For those that do get ripped out, the hole often remains.?ÿ Commonly only set in a busy residential setting (ie. asphalt) or a remote setting (ie. Canadian Shield).?ÿ Mag Nails are a common "goto."?ÿ If setting something in concrete, a cut cross is usually preferred.?ÿ To distinguish monuments from control, local practice is to mark boundary's with a "cross," control with a "T" or non-perpendicular "X."

I have need to go to a corner I found a couple of times about 20 years ago.?ÿ At that time I found a PK nail that had been driven in a crack in bedrock on a very rural, low-traffic gravel road.?ÿ It had already been there over 20 years.?ÿ I bet I find it again.

A headless 2" mag nail would answer the size and composition requirement of that. I find that surprisingly insubstantial.
I do not disagree with that assessment.?ÿ An alternative some employ is to hammer drill a 3/4" hole through the asphalt, monument an IB deep (ie. take another IB, cut off the tip, and use it to sink the first IB deeper so that frost heave is minimized/repave is less likely to disturb it), remove the "sinker" IB, and then backfill with cold patch/epoxy/sand, etc. That minimizes damage to the asphalt while still leaving a monument that will survive the annual snowplow brigade.?ÿ

Due to a number of expensive utility disruptions, the Association (in conjunction w/ suppliers) developed a plastic bar that has a strong magnetic head that makes one's Schonstedt scream.?ÿ It is meant for urban applications where locates have not been done yet or if there is any concern about striking utilities.?ÿ They have a few problems:
1. They always seem to split/break (well, for a neanderthal like me, anyways) at the head on that last sledge strike
2. They're shorter, so a bit flimsier.?ÿ They are short, on purpose, as they are only really meant in high-chance utility areas.
3. They're more expensive than the iron equivalent.
4. It sucks when another company uses them to monoument a block corner.?ÿ Them being flimsier, I do not like them for this application.?ÿ
?ÿ
We, typically, do not monument unless we have locates.?ÿ We use a Short Standard Iron Bar (SSIB) or Iron Bar (IB) if there is any question about locates (ie. if they are close in the area, etc.).?ÿ We have not hit anything at the 14" depth (*touches wood*).?ÿ If one feels really leary about it, we just calc in a witness in the field (1m minimum required by the Act).
I do not disagree with that assessment.?ÿ An alternative some employ is to hammer drill a 3/4" hole through the asphalt, monument an IB deep (ie. take another IB, cut off the tip, and use it to sink the first IB deeper so that frost heave is minimized/repave is less likely to disturb it), remove the "sinker" IB, and then backfill with cold patch/epoxy/sand, etc. That minimizes damage to the asphalt while still leaving a monument that will survive the annual snowplow brigade.?ÿ
But the huge hole that has to be dug to find it...that will damage the pavement...
The idea is that, when retracing, one would find the cold patch/epoxy/sand, remove that, and re-tie the monument.?ÿ The monument should not be set deeper than ~4" w/in the asphalt.?ÿ They would then replace said cold patch/epoxy/sand.?ÿ If a crew decides to disturb the asphalt to tie in a monument, I believe it is their responsibility to fix it back to the original condition or an equivalent.
Another alternative is to set a witness in the grassed boulevard.?ÿ Most of our plans are registered w/ the Ontario Land Registry Office.?ÿ Any following surveyors should pull those plans and know to look for the witness.?ÿ Those plans that are not required to be registered (ie. a Surveyor's Real Property Report) are uploaded to the provincial database.?ÿ It is a centralized GIS where all non-registered notes, plans, etc. are hosted.?ÿ Each firm sets its own fee for other surveyors to purchase said information.?ÿ The fee amount is something still up for debate. Individual firms can set individual rates.
My personal opinion is to set it rather low.?ÿ In theory, one should price the job so that they are paid correctly (ie. your time creating notes should be factored into the quote).?ÿ Any additional income is just..........additional.?ÿ A low fee helps other surveyors assemble a better picture of the cadastral fabric and prevent pin-cushioning.
