CONTRACTOR shall remove all hubs and survey stakes in the Soil Liner Fill and backfill all holes with MANAGER and CERTIFYING ENGINEER approved moisture- conditioned Soil Liner Fill or bentonite. Compact with a Proctor hammer or other suitable device that will achieve a kneading type of compaction and will achieve the required density. 16. CONTRACTOR shall verify the final thickness of Soil Liner Fill to determine compliance with this SPECIFICATION. Thickness verification shall be performed at a minimum frequency of two measurements per acre using a soil-coring device, unless directed otherwise by MANAGER. CONTRACTOR shall record as part of the as-built documentation the location, elevation, and thickness of each Soil Liner Fill verification test. CQA Monitor will witness all verification measurements. CONTRACTOR shall backfill all holes with MANAGER and CERTIFYING ENGINEER approved moisture- conditioned Soil Liner Fill compacted with a Proctor hammer or other suitable device that will achieve a kneading type of compaction and will achieve the required density, or bentonite. Areas with deficiencies shall be reworked by CONTRACTOR, until acceptable measurements are obtained at no additional cost to CC&V. 17. If tests indicate the Work does not meet the requirements of the SPECIFICATIONS, MANAGER and CERTIFYING ENGINEER will establish the extent of the nonconforming area. The nonconforming area shall be reworked by CONTRACTOR until acceptable test results are obtained at no additional cost to CC&V 18. Prior to any geosynthetics being placed on Soil Liner Fill, the area will be tested by CQA Monitor. No geosynthetics will be allowed to be placed on frozen material, as defined in Section 3.06, without the area in question being retested by the CQA Monitor. H. Drain Cover Fill 1. Drain Cover Fill shall be placed over the geomembrane in the locations shown on the DRAWINGS. 2. Prior to placing the Drain Cover Fill, CONTRACTOR shall verify by visual inspection that the underlying geosynthetics are free of holes,tears,wrinkles,or foreign objects. MANAGER and CERTIFYING ENGINEER will inspect the geosynthetic for wrinkles prior to placement of Drain Cover Fill. As instructed by MANAGER, CONTRACTOR shall "work out"wrinkles to the satisfaction of MANAGER and CERTIFYING ENGINEER prior to placement of the Drain Cover Fill. In all cases, wrinkles shall not be of a size that they could fold back on themselves. Wrinkles greater than one foot shall be removed and repaired by the INSTALLER. Page 17
