TASK 3 EARTHWORK <br /> The goal of the earthwork task is to place soil medium on the refuse pile in order to <br /> encourage adequate revegetation. Two drainage channels and a down drain will be <br /> constructed on the pile under Task 2. Prior to topsoiling efforts, final grading will take <br /> place on the refuse pile to reduce over-steep slopes. This grading will be paid for under <br /> Task 5a), Equipment Rental hours for bulldozer. After the construction of drainages and <br /> final grading is complete and approved by the PROJECT MANAGER, the coal refuse <br /> disposal area will have topsoil replaced upon it to facilitate revegetation. <br /> The estimated volume of topsoil that will be placed on the Sutey Refuse disposal area is <br /> 35,000 cubic yards. The figure is based upon one inch (1") to 400 feet scale maps and field <br /> measurements. This is an ESTIMATION ONLY and is stated to give prospective bidders <br /> an idea of the yardage volumes involved. It is the responsibility of the prospective bidders <br /> to determine volumes. <br /> Site Clearing <br /> Prior to initiating earthwork tasks, any remaining equipment, materials or foundations left <br /> behind from the previous mining operation will be buried or removed from the site as <br /> directed by the PROJECT MANAGER. Concrete materials may be hauled to the No's. 1, <br /> 3, or 4 mine entries for disposal against the highwall remnant. Other materials will be <br /> hauled to the main facilities area for removal by others. Likewise, during earthwork <br /> activities, any trash encountered will be hauled to the main facilities area for removal by <br /> others, as designated by the PROJECT MANAGER. Trash includes, but is not limited to, <br /> culvert pieces, abandoned electric lines, cable and miscellaneous metal, debris and timber. <br /> Sutey Refuse Pile <br /> Following excavation of the drainages under Task 2, topsoil will be placed upon the refuse <br /> surface. Approximately 35,000 cubic yards of topsoil material will be spread over the refuse <br /> pile. Slopes with a southern exposure will receive 27 inches of topsoil; slopes with a western <br /> exposure will receive 21 inches of topsoil and slopes with northern or eastern exposures will <br /> receive 15 inches of topsoil. All topsoil depths will be measured perpendicular to the slope. <br /> The three different areas will be staked in the field by the PROJECT MANAGER prior to <br /> topsoil application. The topsoil will be derived from two adjacent topsoil stockpiles. <br /> Compaction will be accomplished up and down slopes so that the track-machine grouser <br /> marks are parallel to the contour. <br /> Measurement and Payment <br /> There will be no measurement for payment. Payment for this task will be reflected in a <br /> lump sum bid under Item 3 on the Bid Schedule. This lump sum will cover payment of all <br /> costs for excavation, transport and placement of the topsoil. Payment shall be as this task <br /> is completed and approved by the PROJECT MANAGER. Payment for task 3 shall be <br /> made only for that amount shown under Item 3 of the Bid Schedule. Any or all incidental <br /> costs incurred shall be reflected in each Task or be paid at the CONTRACTOR's expense. <br /> 7 <br />
