Om surveying a new road being built. The plans call for the ground to slope down at 6:1 from the edge of pavement for 6', then 4:1 to a designed elevation. The dirt guys want me to give them a point at that hinge every 100'. And on a lathe write 6'offset cut or fill to sub-grade (14" below top of pavement) and on the other side of the lathe a cut or fill to the designed elevation at 4:1. this sounds great to me I've got 6 miles of road to stake out and I can whip this out quick. The more I think about it though the more I wonder if the dirt guys realize what they have to do. Not that I don't have faith in them, but I'm not giving them much information for what they're doing. Here's the way I see it: since I'm putting a point every 100' we don't have to worry about one dimension but there is still one horizontal and one vertical. I am giving them point A(h,v) n=cut or fill to subgrade and m=cut or fill to designed toe. They need to find B(edge of road,subgrade), C(edge of road, top of pavement),D(hinge point,finished elevation) and E(toe,at a given elevation) Most of these points are easy to figure out and I don't think they will have a problem, but E(h) is a tough one. Eh=Ah-4((Av+n+2")-(Av+m)) I know it isn't hard on paper but that's a lot of math that I'm sure the guy on the blade doesn't want to think about and if he tries to just use the slope angle and until he hits the target elevation he's gonna wipe out my set point. I've only been surveying for about 6 or 7 months and I do tend to be more precise than I need to be, better safe than sorry. Does what I'm giving them seem like it's enough for them to do the job without TOO much trouble? How would you stake out something like this?
