Was taught that an invert was getting a reading when the level or prism rod was being held upside down.

You had to be careful shooting?ÿinverts with an inverted image alidade. ?ÿKind of like adding two negative numbers. ?ÿ
Obvert is a verb.
I've always called the inside top the soffit, the flow line the invert, and the horizontal line through the center the spring line.
Is this a regional thing?
Yeah it's just a word I picked up somewhere and liked. I can't imagine when I would need to use it. Crown , invert and soffit much more common.
Extrados and intrados, there's another couple that can make it sound like you're an old school expert!

That would be an inverse level
I remember being a straight-up, uncrusted grunt and asking the PC why he kept righting 'high' (HI) in his notes.
That said, top of the pipe has always been the 'crown' in my world.
I was graced by a Senior Field Chief whom gave me a 15 page list of all of our AutoDraft acronyms. After using it enough, it was second nature.?ÿ We should have trained our "inside folks" the same way to avoid the constant queries about " what is an FES?, what does TOP stand for, what is a TOE????"?ÿ Good times.?ÿ No one ever misinterprets FNG though..........?ÿ?ÿ?ÿ 😉

When following?ÿsurveyor A on a slope construction, surveyor B asked what "toe" and "tb" meant.
I agree it's a regional/type of construction thing concerning exactly how to label a slope stake, or any stake for that matter.
Worked briefly for an construction staking outfit that offered temp field crews on an as needed basis.?ÿ It was a nasty situation,?ÿ moving every few days from jobsite to new jobsite; not unusual the previous surveyor had quit due to untimely payment.
Anyway,?ÿ I wrote up a two page picturebook of every possible slope stake terminology on representative diagrams,?ÿ which I gave to the grading contractor upon arrival.?ÿ Some were offended but most accepted it without comment.?ÿ Really helped when there were problems and the finger pointing began.
The entire construction field has been reduced to a ridiculous level. We have to bend over backwards to literally spell out that FILL + 2' means, Add 2' from this mark to get to desired EL. Even with obnoxious writing on the lath, the pad will still be built to a fill mark and we are blamed because they used "our mark" that said Fill + 2'. This has happened recently on more than one occasion recently from more than one construction crew.?ÿ ?ÿ?ÿ
We recently laid out a commercial warehouse, 450' x 140' - A month or so ago. Upon arrival on site, the lot covered in unkept sod was rather soft and had many puddles. I cleared with the site project manager what was to be laid out, "Just the 4 corners and we will take it from there" - No problem. I assumed there would be more to it because of how long it was, but that's what they wanted. Last week we received a call that our box was out of square by 2 3/4" - I checked my data, my poles, and everything was as it should be. We laid the square out by setting the two long sides initially with a bi-pod and calibrated pole, then sighted long and turned 90?ø the short distance, nylon clad steel tape verified EDM distance. Upon returning to the site for a form board tie in, I was informed it was not 2 3/4" out, they were using a fiber tape to pull 450' over segmented distances from offsets I did not set. Then he told me "my" error was reduced to 3/4" after correct taping... On an unprepared lot, soggy as could be I guess they did a good job keeping it down to .06, though I could have done without the immediate scolding and blame. It comes with the territory though I suppose?ÿ
Calamity ahead?ÿ 😉
We would simply put numbers on a stake and mark a line under the numbers for "Fill" and over the numbers for "Cut".
?ÿ
Wow, that would be scary unless you always worked with construction crews that understood the system...?ÿ?ÿ

Everyone needs to have actual face to face conversations with everyone else.
Usually never happens.
$#it happens.................again.
I was trained to write the F or C with the + or - big and proud, legible, and to answer basic questions to any of the operators or Site Managers that had any too.?ÿ The good operators would ask questions, and even make requests for other things ahead of the planned actions.?ÿ It all just comes down to communication, good training, and quality people.?ÿ With out that, its fun to watch only if you're not directly involved in the circus unfolding around you.
It helps when the plans use standard abbreviations and terms.?ÿ My stakes just reference the information on the plans so I try to utilize the plans standard acronyms/ abbreviations.?ÿ Sometimes it is p.c. for point of curvature and sometimes it is b.c. for begin curve, point is I try to relate to the information provided on the plans which is typically standardized by local practice and controlling agency standards.?ÿ Jp
