Limits of excavation, Structural Flll, Select Structural Fill, Coarse Shaft Backfill, Underdrain Fill, <br />Low Volume Solution Collection Fill, Bedding Fill, Leak Detection Fill, Soil Liner Fill, Drain <br />Cover Fill, Fine Shaft Backfill, Pipe Bedding Material and Granulaz Filter Material for the valley <br />leach facility are defined by the lines and elevators shown on the DRAWINGS. All fill shall be <br />placed to the mhlimum thicknesses shown on the DRAWINGS. <br />B. Finished grades shown on the DRAWINGS are given in feet, and shall slope uniformly between <br />given spot and contour elevations, without sag or humps. All grades shall provide for natural <br />runoff. <br />C. The Soil Liner Fi0 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, <br />and the Drain Cover Sll 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 aze inadequate, CONTRACTOR shall backfili trenches to compaction <br />SPECIFICATIONS and relocate trenches at CONTRACTOR'S expense. <br />F. Correction of overexcavafion and bacls~'illing shall be to CONTRACTOR'S account. <br />QUALTTY ASSURANCE: <br />A. All work shall be monitored and tested in compliance with the requvements of the CQA Plan. <br />B. CONTRACTOR shall be awaze of all testing activities outlined in the CQA Plan, and shall <br />account for these activities in the construction schedule. <br />C. All CQA sails testing (both field and laboratory testing) will be the responsibility of <br />CERTIFPING ENGINEER, as identified in the Earthworks CQA plan. CONTRACTOR <br />shall be responsible for cooperating with CQA Monitor during all testing activities. <br />CONTRACTOR shaft provide equipment and labor to assist CQA Monitor in sampling, if <br />requested, and shall also provide access to all azeas requiring testing acfivities. Quality Control <br />testing shall be the responsibility of the CONTRACTOR. <br />Section 02200 Page 1 of 17 Mazch 22, 2000 <br />Earthworks Golder Associates Revision 7 <br />I:~OM1JOBSW`43-21]OUVC CERTIFICATION REPORTPHaCF NC OSA CERNPPENDICIESAPPENDIXE'rECHMCAL SPECIFICAT[ONSb2200R].DOC <br />
