I have a neighbor that wants to put up a hog barn and I have a dozer and excavator and they want to know if im interested in the job. Mostly I just do stuff for our own farm but its something im willing to do. The barn is going to be 54x200 with and 8ft deep pit and the measurments is with 3' overdig. its on flat ground so i'll probably rent a scraper for the majority of it and place the dirt around the edges of the barn so there really isn't any long hauls. They just want an estimate of what its going to cost. I have a D6R and a 324DL and would probably rent a 15 or 18yd scraper. Can anybody help me out on what to charge? or charge per yard?
