A neighbor/building contractor approached me the other day and ask if I would be interested in digging a 25'x25' foundation for an attached garage he will be building for a client. With the exception of digging my garage foundation I have only used my equipment for my landscaping buisness and charged an hourly rate otherwise. I want to give him a reasonable bid for the complete job but I feel I am a bit unexperienced with pricing a job like this. I know discussing numbers is a bit touchy but any thoughts would be appreciated. I would be using a 331 mini-x and s175 and the job would include removing asphalt (20x20 section), digging three walls (sandy soil),backfilling, compacting, and most likely removing any leftover material. My best guesstimate would be three partial days and travel is all around pretty close. Is 1500.00 too high? too low? Thanks again for any info!
