I am in need of some help. I have a bid that I need to put in on what it would cost to build a burm that is 150'Lx4'Hx6'W. It is the shape of a hook. I don't know how much dirt I will need. I do know that the customer would like a mix of 30%organic soil and 70%topsoil or clay topsoil. Any suggestions on the best equipment to use to make the burm 4' high X 6' wide. The ground is fairly flat, meaning there aren't many dips or low spots. Also what does the normal truck of soil cost? I feel it would be easier to shape a burm that is wider but it is what the customer wants. Any feedback will be greatly appreciated.
