The equipment use hours for the excavator <br /> is listed for 10 hours since it will be idle approximately 30 percent <br /> of the time. The loader will be used to haul the on site rock from <br /> the stockpile area to the project and place it as needed. We estimate <br /> the loader will be needed for 3 hrs to complete the rock moving task <br /> and placement of each load. We have included 8 hours of general labor <br /> to allow for pipe placement, and miscellaneous labor for the project. <br /> Approximately 1.25 acres will need revegetation or remedial <br /> corrections on the project site. <br /> CONSTRUCTION COST ESTIMATE <br /> 1.
