I'm working on a bid for sodding 100k-175k sq ft. Topsoil will be stockpiled on site and will need to be spread at 3 to 4 inches. I'm by no means an operator compared to most guys in this section, but I can and have run backhoes, excavators, and skids. How many 8hr days am I looking at with a large frame CAT machine. Without much experience on this scale, I was thinking about a 5 day workweek would cover it. Opinions, suggestions?
