This is within 10% on the LCCA (even with 6” concrete shoulders vs 4” asphalt shoulders). I know the locals tend to prefer concrete, so I’m hoping the final pavement selection is the concrete option? Please confirm, and if nothing else, we definitely want alternate bid if not concrete pavement outright.

It looks like the ‘whitetopping’ option is 7” for a 20-year concrete design. 4” of bituminous get’s 20-years too, so this LCCA is obviously wrong. I’d imagine a true 20-year concrete whitetopping would come in about 5-5.5” thick, and the 7” is at least a 35-year design (it should get credit for that at least). This job highlights the bigger issue I’ve mentioned before of the new MnPAVE rigid only outputting 7” minimum pavements. Please let me know when a corrected LCCA will be issued, as this one is pretty egregious.
