Limits of excavation, Structural Fill, Select Structural Fill, Coarse Shaft Backfill, Underdrain Fill, <br />Low Volume Solution Collection Fill, Bedding Fill, Leak Detection Fill, Soil Liner Fill, Drain Cover <br />Fill, Fine Shaft Backfill, Pipe Bedding Material, and Granular Filter Material for the valley leach <br />facility are defined by the lines and elevations shown on the DRAWINGS. All fill shall be placed to <br />the minimum thicknesses shown on the DRAWINGS. <br />B. Finished grades shown on the DRAWINGS are given in feet, and shall slope uniformly between given <br />spot and contour elevations, without sag or humps. All grades shall provide for natural runoff. <br />C. The Soil Liner Fill and Bedding Fill shall have a minimum thickness of 1.0 foot. <br />D. The Low Volume Solution Collection Fill will have a minimum thickness of 3.0 feet at all times, and <br />the Drain Cover fill will have a minimum thickness of 2.0 feet at all times. <br />E. Clearance of pipes with respect to regulated boundaries will be checked by MANAGER. If <br />clearances are inadequate, CONTRACTOR shall backfill trenches to compaction <br />SPECIFICATIONS and relocate trenches at CONTRACTOR's expense. <br />F. Correction of overexcavation and backfilling shall be to CONTRACTOR's account. <br />1.04 QUALITY ASSURANCE: <br />A. All work shall be monitored and tested in compliance with the requirements of the CQA Plan. <br />B. CONTRACTOR shall be aware of all testing activities outlined in the CQA Plan, and shall account <br />for these activities in the construction schedule. <br />C. All CQA soils testing (both field and laboratory testing) will be the responsibility of CERTIFYING <br />ENGINEER, as identified in the Earthworks CQA plan.
