Newmont-Cripple Creek&Victor Gold Mine <br /> Technical Specification No.02200.DOCX ■ <br /> Squaw Gulch VLF <br /> Project No.475.0106.006 <br /> June 15,2016 <br /> 9. CONTRACTOR shall compact corners and other areas inaccessible to driven <br /> compaction equipment using hand-operated 500-pound vibratory plate or vibratory <br /> smooth-drum compaction equipment approved by MANAGER and CERTIFYING <br /> ENGINEER. <br /> 10. CONTRACTOR shall trim the surface of the Soil Liner Fill to the design grades shown <br /> on the DRAWINGS. <br /> 11. CONTRACTOR shall roll the surface of the Soil Liner Fill with a smooth drum roller <br /> to remove ridges and surface irregularities greater than 0.5 inches in height. <br /> CERTIFYING ENGINEER shall determine if surface preparation is sufficient to place <br /> geomembrane. On areas with slopes steeper than 3H:1V, CONTRACTOR shall adopt <br /> 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 <br /> on the surface of the Soil Liner Fill from grading equipment shall be repaired by <br /> CONTRACTOR prior to placement of the geomembrane by rolling the surface as <br /> approved by CQA Monitor. <br /> 12. CONTRACTOR will remove angular protruding rocks greater than 3/4 inches in <br /> diameter from the compacted Soil Liner Fill surface. Indentations left in the Soil <br /> Liner Fill Surface after removal of the rocks shall be filled with Soil Liner Fill or other <br /> suitable fill approved by CQA Monitor, and compacted to achieve final grade. Areas <br /> of the Soil Liner Fill surface with concentrated gravelly areas will have suitable fill <br /> approved by CQA Monitor placed on top and compacted to achieve final grade. A <br /> maximum thickness of 0.5 inches of suitable fill will be placed on the Soil Liner Fill. <br /> 13. MANAGER and CERTIFYING ENGINEER will identify any areas of significant <br /> desiccation, crusting, or erosion of a lift surface. Soil Liner Fill surfaces found to <br /> have desiccation cracks greater than 0.25-inches in width or depth, or which exhibit <br /> swelling, heaving or other similar conditions shall be replaced or reworked by <br /> CONTRACTOR to remove such defects. Desiccation cracks on the Soil Liner Fill <br /> surface less than 0.25-inches in width or depth shall be compacted with a smooth <br /> drum roller. CONTRACTOR shall take whatever steps necessary to prepare Soil Liner <br /> Fill surface to the satisfaction of MANAGER and CERTIFYING ENGINEER, at no <br /> additional cost to CC&V. <br /> 14. CONTRACTOR shall maintain the Soil Liner 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 Soil Liner Fill surfaces or other portions of the Work that have or have <br /> not been covered by geomembrane, at no additional cost to CC&V If any moisture <br /> is allowed to collect under the geomembrane prior to or after final seaming and <br /> softens the Soil Liner Fill, the geomembrane shall be removed and CONTRACTOR <br /> Page 16 <br />
