Just trying to review my pricing. Some days I think I am too high and others I feel like am too low. But then things always look to come out right. I am bidding a 185' drainage job that I don't want to lose on. Basically renting a mini excavator and taking a trench down the side of the driveway, putting in 2 or 3 drain boxes and then running the pipe to the street. just looking for a guesstimate for what I should be around. Any help would be great!
