amec, <br /> Underdrain System: <br /> Primary Underdrain: No work was performed on the Primary Underdrain. <br /> Secondary Underdrain: Approximately 40 feet of Secondary Underdrain was installed near <br /> station A6+00 and tied into existing underdrain. <br /> Tertiary Underdrain: No work was performed on the Tertiary Underdrain. <br /> B) Underground Workings <br /> Underground working#6557 was backfilled per project specifications and is considered <br /> remediated. <br /> Underground working 46446 was blasted. Additional remediation is required. <br /> Confirmatory drilling was conducted at underground workings UG#6119 and UG#6621. Voids <br /> were encountered during drilling activities. These workings will require further remediation. <br /> Confirmatory drilling was conducted at underground working UG#6089. No voids were <br /> encountered during drilling activities. The site was blasted, shot rock removed, and backfilled <br /> according to project specifications. The working is considered remediated. <br /> Underground working#6279 was excavated to competent rock, backfilled according to project <br /> specifications, and is considered remediated. <br /> 11) Storm Water Management <br /> Best Management Practices (BMPs) are being performed. <br /> CQA ACTIVITIES: <br /> 1) Field Activities: Observation of construction activities during this reporting period included: Slope <br /> grading and fill placement; underground working remediation and confirmatory drilling; production <br /> drilling and blasting; sampling and testing of DCF and SLF material; final subgrade acceptance <br /> certification of the southern half of the PSSA floor; and Secondary Underdrain installation. <br /> 11) Laboratory Activities: Laboratory testing continued with permeability, particle size distribution, <br /> Atterberg limits, moisture-density relationships, gradations, material classification, identifications, and <br /> field material sampling were performed during this reporting period. <br /> The following samples were collected and returned to AMEC's laboratory for analysis: <br /> Drain Cover Fill sample number DCF 84. <br /> Soil Liner Fill sample numbers SLF 150S and SLF 151 S. <br /> General Proiect Items <br /> Meetings and Discussions: <br /> Y The weekly Contractor Meeting occurred on May 28, 2014 with CC&V Projects, AMEC, and <br /> Ames. <br /> A VLF surface acceptance certification and liner construction coordination meeting was held <br /> between AMEC, Ames, and CC&V on May 29, 2014. <br /> MLE2 WE 31 MAY 2014 FINAL Page 3 of 7 <br />
