I am working on a pavement rehabilitation project where the bulk of the work is milling, resurfacing and some widening. I only need to create cross sections (hence, corridor) in the area we have widening.
I have been told that we don't need a proposed profile because it's a simple mill/overlay. I do not know, however, how to create a corridor without a profile and I'm not entirely certain how to generate a profile from the existing ground.
I think that I could create a point (null?) that I could project to surface for my "centerline" and control my template from that. It gets even more fun in the areas where we have medians of various sorts...
Am I overthinking this?
I am watching the Overlay, Stripping and Widening learning path course but they haven't really talked about how this works if you don't have a profile yet. Maybe they do further on?
