ameO <br /> Underdrain System: <br /> Primary Underdrain: Approximately 190 feet of primary underdrain was installed in the northern end of the PSSA <br /> floor in general accordance with approved project plans and specification. <br /> Secondary Underdrain: Approximately 390 feet of secondary underdrain was installed above and tied into the <br /> primary underdrain on the north end of the PSSA. <br /> Tertiary Underdrain: No work occurred on the tertiary underdrain. <br /> B) Underground Workings <br /> Confirmatory drilling occurred at Underground workings#6557 and#6280. Following the drilling,the workings were <br /> blasted,shot rock was removed,and then backfilled with structural fill according to project specifications. Working <br /> #6280 is considered remediated;working#6557 requires additional backfill before remediation is complete. <br /> ti)Storm Water Management <br /> Best Management Practices(BMPs)are being performed. <br /> CQA ACTIVITIES: <br /> I) Field Activities: Observation of construction activities during this reporting period included: Slope grading and fill <br /> placement; Underground working remediation and confirmatory drilling; Production drilling and blasting: Sampling and <br /> testing of WHEX Clay, DCF and SLF; Final subgrade acceptance certification at the ADR platform; and Primary and <br /> Secondary underdrain installation. <br /> II) Laboratory Activities: Laboratory testing continued with Permeability, Particle Size Distribution,Atterberg Limits, <br /> Moisture-Density relationships,gradations,material classification, identifications, and field material sampling were <br /> performed during this reporting period. <br /> The following samples were collected and returned to AMEC's laboratory for analysis: <br /> Drain Cover Fill sample numbers DCF 81 through DCF 83. <br /> Soil Liner Fill sample numbers SLF 146S through SLF 149S <br /> 5= Test Sample TS-62(clay)from the WHEX Pit. <br /> General Proiect Items <br /> Meetings and Discussions: The Contractor Meeting occurred on May 21, 2014 with CC&V Projects,AMEC,and Ames. <br /> Summary of Concerns: None. <br /> CC&V:Daily updates, reporting and scheduling are some of the tasks occurring between CC&V Projects,AMEC, and Ames. <br /> Miscellaneous: <br /> Drain cover fill processing continued. <br /> Rip rap processing continued. <br /> Geophysical surveying was conducted in the PSSA. <br /> ' A dozer was finish grading at the Water stand pond. <br /> Deliveries: None <br /> Page 3 of 7 MLE2 WE 24 May 2014.doe <br />
