What other types of materials/layers are included in the <br />design (e.g., asphalt -tar, gravel for gas venting)? <br />N.A. <br />Note: Thickness of individual layers may be modified <br />depending on the integrated cover design. <br />22. Construction Quality Assurance <br />The following cost estimates apply to the quality assurance <br />activities necessary to ensure that the final cover is <br />installed properly, as specified in the design parameters, <br />and fulfill the conditions mandated by regulations. <br />a. Monitoring costs incurred while evaluating the final <br />cover system components: <br />1) Laboratory test fees (e.g., soil permeability, soil <br />density and moisture content) <br />$ 52,000 <br />2) Field test expenditures (e.g., test pad field <br />permeability tests, relative compaction tests) <br />$ 130,000 <br />b. Inspections (e.g., initial inspection of native and <br />imported soil or clay, visual check of completed cover) <br />$ 0 <br />c. Reporting costs (e.g., daily reporting procedures, <br />corrective measure reports) <br />$ 0 <br />d. Engineering design costs $ 0 <br />e.
