Thomas2,

Be careful on your stone calculations. You are assuming a 100% flat subgrade and exactly 10' width. Even the best operators will experience a 10% overrun vs clean dimensions. Also make sure that your yield rate on the stone is not based on loose volume but rather compacted. I come up with around 350 tons @ 8" depth. That is without waste figured.

If I was pricing the job for you, I would be around $9500. That would be for 8" of stone and all the grading work. What I was refering to before was hiring a small excavating contractor by the hour to do the work and you buy the materials. By your calculations, you would save $600 to $800 vs hiring a contractor to do the work. 400 tons per day on a 10 driveway is just about a full days work for a seasoned operator. It would also take an experienced guy at least a day to prepare for the stone. I'm guessing about 20 hours @ $80 per hour for what you need. I don't believe that someone who has never run a dozer before can complete that job in 2 days with a D4.

This is based on my experience as a cost estimator/project manager in this line of work for the last 15 years. I've been around some of the best in the business, and they wouldn't finish in any less than 2 days.
