a top and compacted to achieve final grade. A maximum thickness of 0.5 inches of suitable <br />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 have <br />desiccation cracks greater than 0.25- inches in width or depth, or which exhibit swelling, <br />heaving or other similar conditions shall be replaced or reworked by CONTRACTOR to <br />remove such defects. Desiccation cracks on the Soil Liner Fill surface less than 0.25- inches <br />in width or depth shall be compacted with a smooth drum roller. 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 />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 Plan <br />until the surface is covered. CONTRACTOR shall repair all weather related damage to <br />Soil Liner Fill surfaces or other portions of the Work that have or have not been covered by <br />geomembrane, at no additional cost to CC &V. <br />If any moisture is allowed to collect under the geomembrane prior to or after final seaming <br />and softens the Soil Liner Fill, the geomembrane shall be removed and CONTRACTOR <br />shall recondition and recompact the Soil Liner Fill to meet all placement and trimming <br />SPECIFICATIONS, at no additional cost to CC &V. <br />15. CONTRACTOR shall remove all hubs and survey stakes in the Soil Liner Fill and backfill <br />• all holes with MANAGER and CERTIFYING ENGINEER approved moisture - <br />conditioned Soil Liner Fill or bentonite. Compact with a Proctor hammer or other suitable <br />device that will achieve a kneading type of compaction and will achieve the required density. <br />16. CONTRACTOR shall verify the final thickness of Soil Liner Fill to determine compliance <br />with this SPECIFICATION. Thickness verification shall be performed at a minimum <br />frequency of two measurements per acre using a soil -coring device, unless directed <br />otherwise by MANAGER. CONTRACTOR shall record as part of the as-built <br />documentation the location, elevation, and thickness of each Soil Liner Fill verification test. <br />CQA Monitor will witness all verification measurements. CONTRACTOR shall backfill <br />all holes with MANAGER and CERTIFYING ENGINEER approved moisture - <br />conditioned Soil Liner Fill compacted with a Proctor hammer or other suitable device that <br />will achieve a kneading type of compaction and will achieve the required density, or <br />bentonite. Areas with deficiencies shall be reworked by CONTRACTOR, until acceptable <br />measurements are obtained at no additional cost to CC &V. <br />17. If tests indicate the Work does not meet the requirements of the SPECIFICATIONS, <br />MANAGER and CERTIFYING ENGINEER will establish the extent of the <br />nonconforming area. The nonconforming area shall be reworked by CONTRACTOR until <br />acceptable test results are obtained at no additional cost to CC &V <br />18. Prior to any geosynthetics being placed on Soil Liner Fill, the area will be tested by CQA <br />Monitor. No geosynthetics will be allowed to be placed on frozen material, as defined in <br />Section 3.06, without the area in question being retested by the CQA Monitor. <br />• <br />Section 02200 Page 14 of 18 September 3, 2008 <br />Earthworks Revision 1 <br />SAProjects \1125E CCV CQA \I - Tech Specs\02200.0.doc <br />
