J. Bedding Fill <br />• 1. Bedding Fill shall be placed within the limits of the valley leach facility as shown on Ute <br />DRAWINGS and shall begin only after completion of all, or MANAGER and <br />CERTIFYING ENGINEER approved portion of, excavation and placement of the ore <br />slope regrading and end berm material in the valley leach facility. <br />2. CONTRACTOR shall place and wmpact the Bedding Fill in loose lifts such that the <br />compacted lift thickness is a minimum of 12-inches. CONTRACTOR shall condition <br />the Bedding Fill to allow a surface that does not cause rutting or other deleterious <br />effects. The moisture content and density shall be uniform throughout the lift. If a lift <br />of compacted Bedding Fill dries out during placement operations, CONTRACTOR <br />shall scarify, moisture condition the dry soil and recompact the lift. If a lift of <br />compacted Bedding Fill becomes overly wet due to precipitation or over watering, <br />CONTRACTOR shall allow the wet soil to dry to the specified moisture content range <br />before recompaction of fill and placement of geosynthetic materials. <br />3. CONTRACTOR shall assist CQA Monitor in obtaining soil samples for CQA testing. <br />Bedding Fill sampling shall be scheduled by CQA Monitor with CONTRACTOR to <br />facilitate CQA field testing. <br />4. CONTRACTOR shall trim the surface of the Bedding Fill to the design grades shown <br />on the DRAWINGS. <br />5. CONTRACTOR shall roll the surface of the Bedding Fill with a smooth drum roller to <br />remove ridges and surface irregularities greater than 0.5 inches in height. <br />CERTIFYING ENGINEER shall determine if surface preparation is sufficient to <br />• place geomembrane. On azeas with slopes steeper than 3H:1 V, CONTRACTOR shall <br />adopt methods as necessary to obtain the same final surface preparations that would be <br />obtained by the passage of a smooth-drum roller on flat or level ground. Pushing of <br />compaction equipment by tracked equipment shall not be performed. Wheel ruts on <br />the surface of the Bedding Fill from grading equipment shall be repaired by <br />CONTRACTOR prior to placement of the geomembrane by rolling the surface or <br />placing and compacting tailings as approved by CQA Monitor. CONTRACTOR shall <br />take whatever steps necessary to prepare Soil Liner Fill surface to the satisfaction of <br />MANAGER and CERTIFYING ENGINEER, at no additional cost to CC&V. <br />6. CONTRACTOR shall maintain the Bedding Fill surface in a condition suitable for <br />geomembrane installation as specified in these SPECIFICATIONS and in the CQA <br />Plan until the surface is covered. CONTRACTOR shall repair all weather related <br />damage to Bedding Fill surfaces or other portions of the Work that have or have not <br />been covered by geomembrane, at no additional cost to CC&V. <br />If any moisture is allowed to collect under the geomembrane prior to or after final <br />seaming and softens the Bedding Fill, [he geomembrane shall be removed and <br />CONTRACTOR shall recondition and recompact the Soil Liner Fill to meet all <br />placement and trimming SPECIFICATIONS, at no additional cost to CC&V. <br />7. CONTRACTOR shall remove all hubs and survey stakes in the Bedding Fill and <br />backfill all holes with MANAGER and CERTIFYING ENGINEER approved <br />material. <br />8. CONTRACTOR shall verify the final thickness of Bedding Fill to determine <br />• compliance with this SPECIFICATION. CONTRACTOR shall record as part of the <br />as-built documentation the location, elevation, and thickness of each Bedding FiII <br />verification test. CQA Monitor will witness all verification measurements. Areas with <br />Section 02200 Page 16 of 17 Mazch 22, 2000 <br />Earthworks Golder Associates Revision 7 <br />
