C. The as-built survey was completed and checked by Vector. The permeability <br /> of the clay was tested and was within specs. <br /> D. Miscellaneous finished grading was completed. <br /> E. The sump was excavated and finished. <br /> F. Geomembrane, geonet, geocomposite and GCL rolls have been delivered <br /> and logged in by Vector monitors. <br /> 3. Projected schedule: <br /> A. Guinn provided copies of the updated construction schedule. <br /> B. Guinn will continue to moisture condition the clay until it is covered with liner. <br /> C. GSE will begin deployment of synthetics tomorrow. <br /> D. Guinn will send their forces home after tomorrow until the floor is completed <br /> by GSE (except for a water truck). Guinn will return on July 8. <br /> 4. Coordination of schedules: <br /> A. GSE will line up the slope from the floor of the D-99 cell up to the first bench <br /> on the east side. This should take one to two days. They will then <br /> concentrate on placing liner over the clay on the floor. This will be necessary <br /> because hot weather is here and the clay could desiccate. <br /> B. GSE will take about 4 days to cover the floor plus one day to finish the sump. <br /> C. Vector will do destructs on-site. GSE will do their QC as they go so that <br /> Vector can approve sections of liner. <br /> D. GSE will try to start on the floor on Thursday. <br /> E. Both GSE and Guinn will be off on Saturday, Sunday, and Monday for the <br /> Fourth of July. Guinn will leave a water truck on-site to keep the clay moist. <br /> F. GSE will need 3—4 feet of liner to tie into the D-98 cell. <br /> G. Allied is finishing the ash pit slopes in preparation for liner placement. <br /> H. GSE will complete the eastern slope in 6 days with the ash pit taking 5 days. <br /> It will take about 3 weeks total for the job. <br /> I. GSE is concerned about weather if they start on the floor. The risk of the clay <br /> desiccating is greater than rain damage. GSE was informed that they were <br /> told to start lining on the week of June 14th. If they had started then, the <br /> slopes would be covered and they would be ready for the floor. <br /> 5. Field observations, problems, conflicts, and changes: <br /> No issues. <br /> n:/98601 1.01[Weekly Progress Meetings/06-29-99 Meeting 4.doc Page 2 <br />
