New Survey RulePosted by MightyMoe on August 2, 2022 at 1:54 pm
This should be a rule for every designer: Surveyors that don’t do construction should never have to deal with a spiral curve.
It should be carved in stone and put at the entrance to all highway/railway engineering offices!!!!
Now, back to the horror of my morning computations,,,,,,,,,,IN METRIC!!!!!

C’mon Moe, you can do metric, its as easy as counting from One to Ten…

it’s the metric merging along the feet, the original simple curves turned into spiral, the jog stations placed 2M after the TS, well it’s a sh!!sho#. Metric is simply icing on the cake.
Why did the old timers seem to understand the curve relationships but not the new designers?
I don’t think we’ll see some of this anymore, the department has gotten wise to the button pusher computer jockeys.
You do know that in feet we also count one to ten.

Who was the goofball that decided trigger-nometree was so incredibly easy that he decided to invent hyperbolic trigger functions.

we wrote an archaic program for the 41, in 1991 just to check the other software available for the only bridge
job we ever have done in the metric system. whole lot of heiney scratching. lol. all good in the end.

But when a roof has a slope of 4/12 everyone just uses inches on the square. No need for those danged never ending decimals.

I shouldn’t have mentioned the spiral nightmare ROW was infused with meters, it’s not much better if the mess was created using the foot.
Point being: use a simple curve for the ROW, do whatever for the construction of the Highway, the resulting centerline for the ROW isn’t going to vary much from the construction centerline when properly done. And jogging the ROW a few feet passed the TS out 30?
Saved the payment for 150sqft at $1k per acre of pasture land but added an extra headache writing the description and added another concrete monument at $150 or whatever they cost back then, plus the time installing them.
Just jog at the PC and PT when it’s a little bigger. If you need land beyond the PC or PT sure, add the extra monuments. What is also fun about this project is that the acquisition deeds are written backwards from the stationing. The stations run west to east the deeds are written east to west. Fun times. Almost every spiral has a jog.
