PC on one of our new subdivisions said the curb and gutter was being done with machine control, no stakes at all.?ÿ
And it's not GPS machine control, the curb machine has a prism control device. All the dirt work was done with machine control, I assume some stakes for sewer,,,,,,but maybe not.?ÿ
As technology progresses I see less and less staking for surveyors. I do see the opportunity and increase of providing very good control and as builts ?ÿi am on a job now full blown construction sites ?ÿand all we are doing is as builts and materials inventory type stuff. I do a little staking usually in areas that are in steep slopes and things like limits of disturbance is about it. They do machine control and rtk themselves. On one area I have learned to get ahead a bit when time allows and just start checking there layout so i know ahead of time if it??s going to be a problem or not. We have to have a crew on site anyway. And when i do catch a issue they love that and can get it fixed before it??s built. Use to years ago we staked everything just about. Are you seeing that trend as well i have only been back on private sector side about 3 years now so it is a drastic change to see all of this.?ÿ
Probably has 2 prisms if it doesn't have gps.?ÿ One for location and the other for grade.?ÿ I set up control and did the machine control files for a bunch of curb and gutter in Paducah Ky. at the I-24-US 60 interchange where we built a double crossover diamond.?ÿ On that one they used GPS for location and robot for grade.?ÿ Only set hubs where they started each run so they had something to check.?ÿ I think that was a Leica system.
Surveyors: There is nothing worse than pounding stakes on a dusty (or muddy) construction site all day long. I hate it with a passion.
Also, Surveyors: Machine control is taking our jobs away
Machine control is taking our jobs away
Fewer jobs for hub pounders, more for digital model makers.
The day tradies are smart enough not to require everything marked will be day world peace is achieved.
from what I've seen, the machine control using robotic TS' for guidance are normally graders, curb machines and occasionally pavers. machine control manufacturers saw the the opportunity for it when GNSS couldn't meet certain tolerances or where signal was limited. mainly seen this on the heavy highway projects and very rarely in land development (at least around here). usually GNSS machine control is still the way to go without getting a grade crew too confused on setup

Excellent!?ÿ Now they can only blame themselves when something gets screwed up.
I don't mind automation and increased productivity. It's pretty amazing what we can do with a small fraction of the labor as we needed in the past, and how much faster we can do it.
I do somewhat mind that all this increased productivity has not resulted in fewer hours worked and/or increased pay relative to the "pre-automation" period. (I'll take a 20-30 hour work week or double pay, one or the other, please and thank you...)
I remember @roadhand was working on a big highway job in Texas; he wanted to know the best way to test the 3 different robotic total stations they were using to run the paving machines. Seems that the bean counters realized an eighth of an inch, over the entire job, was worth a million bucks! and they wanted to make sure they were getting their monies worth.
?ÿ
I told him to tell them; a sixteenth was worth 500 thousand, we aren't we chasing that!!!

There is actually opportunity there, if you look...
and seize it. ?????ÿ
We are in the process of testing a "robot" to perform layout. The "robot" is built for uneven terrain and uses a paint can to "mark the spot" for the nail. Granted, this would be best for Hz only layout.?ÿ
After our initial demo last week, it has become aware that the "robot" does not get corrections from GPS so getting the repeatability is hard to do at this point. We shall see how it goes as the testing advances.?ÿ

They will still blame survey even if we never see the site! ?????ÿ
Just wait.
Thinking the same,,,,,,,good reason not to do modelling. Instead of "it's the surveyor's fault" we now move to "it's the model's fault"!!!!
It was such an obvious mistake, they should've caught it before it became a problem: is always a good come back
?ÿ
Don??t forget the engineers. ?ÿOnce they realize they can take the design and push it straight to the machine they will not wants us Survey vermin either lol. Tis why Land Surveyors shousld strive to become the experts in datums measurements and the dont give up 1 inch for boundary or anything that pertains to boundary. ?ÿOr we will take ourselves out

as somebody who's built quite a few in the last decade - this is true and they'll blame the model or model builder every time. I have learned to turn on surface settings where you can see minor contours shown as 0.1' vertical intervals and the majors as 1' where grades are flat. It is always an egg in the face when you cranked a model out quickly because somebody was screaming for it but forgot to check where the pc or pt on curb line meets a tangent and the curb there might've been drawn as two different 3dpolylines and their vertices were at significantly different elevations somehow (less than a foot typically as you'd see the contour jump but more than say a tenth).
?ÿ
I've had several dozer operators get out of the machine and ask why the blade suddenly jumps while they're following the polyline for the curb that the model had. The experienced operators usually know why and have already pulled up up the polylines and queried their elevations to show you ???? whereas if you get the contractor's GPS rover guy checking cuts asking you, normally you can explain it to him, even stake it and he can coordinate with the operators to help them freehand that point's grade

You meant to say "...don't give up 1 TENTH...right? ????
@ric-moore well I reckon you are correct. But i am practicing for my next career. ?ÿMaybe i can be a plumber lol. Yes tenth. I should have said tenth. Send me back to school. Lol. Nice catch. Made my day.
