Perform all necessary pumping required to maintain excavations in <br />a dewatered condition. <br />B. The surface of the existing embankment will be scarified, moisture conditioned and <br />compacted to the satisfaction of the engineer prior to fill placement. The top foot <br />of the existing embankment soil maybe removed if requested by the engineer. The <br />engineer will also evaluate any fill placed on the top of the existing embankment <br />prior to the commencement of construction to determine its suitability as fill material <br />and to determine any additional work required to prepare said fill. Any material <br />removed during the site preparation will be stockpiled or wasted as directed by the <br />Owner. <br />C. Prior to placing any embankment fill material, foundation areas will be prepared by <br />removal of any topsoil and vegetation and any loose or deleterious material. Soil <br />surfaces within the foundation area will be scarified to a depth of one foot, moisture <br />conditioned and re-compacted to a minimum density of 90 percent of Modified <br />Proctor density as determined by ASTM D1557. The prepared foundation surfaces <br />shall be inspected and approved by the Engineer. The Engineer will make every <br />endeavor to approve all foundation surfaces, which will accept embankment fill, in <br />a timely manner in order to preserve these surfaces and to insure continuity during <br />construction operations. <br />D. Any damage resulting from the Contractor's operations during the site preparation <br />or excavation shall be repaired at the expense of the Contractor and to the <br />satisfaction of the Engineer. <br />E. Ditches, spillways and ponds shall be excavated to the lines and grades shown on <br />the Drawings, and temporary culverts and access ramps shall be used, as required, <br />where ditches, or pipe trenches cross existing drainageways. <br />F. Excavation, control of sediment, and restoration in borrow areas shall be performed <br />in accordance with the requirements of the Company or operator of the borrow <br />area. <br />LOAD AND HAUL <br />A. The Contractor may be required to construct a haul road from stockpile areas to the <br />embankment area. The Contractor shall maintain and keep open at all times the <br />access road to the mine/mill where the haul road from the stockpile crosses that <br />road. The Contractor shall fill any wheel ruts caused by the Contractor's hauling <br />units as they develop. At the end of daily operations, and also the completion of <br />hauling, the haul road crossing of the mine/mill road shall be restored to the same <br />condition as the mine/mill road was in at the start of the project. <br />' J:16461\SPECSFNL.WPD <br />Earthwork <br />02200-7 <br />
