I am bidding on a job involving cleaning out a creek which flows through a ladys front yard, this creek has much debris in it but she has a place to dump the debris at via the backhoe. She wants to line it w/Rip Rap stone. This creek is 140' in length and shall be sloped to be 9' wide and a pipe installed which is to be supplied by the owner for vehicle crossings. The stone after hauling is $1900.00, my price. The supplies including the back hoe, stone, fabric, sod staples, grass seed, lime, fertilizer and wheat straw come to around $2650.00. I am estimating this project to take 2 days w/the massive amount of tractor time involved trucking the stone and moving dirt. I am bidding this job at $5410.00. What do you guys think? Does the bid sound about right?
