Damn, they just dug it all up again. What a mess. About the same as many Luperon streets. Don't understand why. Any reasonable Civil Eng can design this, and, more important, anyone can do site inspections on a daily basis, to ensure all the steps are being followed.
My son, a Civil, put a new floor on his house, and learned a huge amount from the inspector. In this case, the design revolves around the amount of rebar, and the thickness of concrete. If designed properly, easy to monitor.
Actually impressed at how thoroughly they are doing the streets
