An Amec field representative observed the placement and compaction of structural fill for the HWY 67 embankment. <br />(See Figure 1). A Cat D10 and a Cat D8 were utilized to push and place structural fill in 18 to 24 inch loose lifts, then <br />compacted each lift with a minimum of 4 passes (by Method specification) using a Cat 563 smooth drum roller. In <br />addition a Cat 330 hammer hoe was used to split rock in excess of 24- inches, prior to compaction efforts. <br />An Amec field representative monitored structural fill material temperatures placed within the Hwy 67 embankment <br />during all shifts. Average structural fill temperatures were above 32 °F <br />Secondary Underdrain: <br />No work was performed on the Secondary underdrain during this reporting period. <br />A total of 1380 feet of Secondary underdrain has been completed. <br />Primary Underdrain: <br />No work was performed on the Primary underdrain during this reporting period. <br />A total of 1280 feet of Primary underdrain has been completed. <br />Temporary Underdrain: <br />Temporary underdrain pipe is installed thru the embankment. No other work occurred during this reporting period. <br />Underdrain Ponds: <br />Concrete for the underdrain Ponds are complete. No other work was performed. <br />Tree /Slash Clearing, Chipping: <br />Seed Masters paused operations until further notice. <br />B) Underground Workings <br />Confirmatory drilling was not performed during this reporting period.. <br />During this reporting period exploratory excavation was performed on UG working No. 6132. This site will continue <br />with excavation into bedrock as remediation continues as specified. <br />During this reporting period remediation efforts were performed and completed on UG working No.6134, <br />No.U6136. Sites listed were excavated to practical refusal into rock varying depths depending on the working <br />remediated. The site for each working was then backfrlled in 2 foot loose lifts to approximate planned subgrade <br />elevation using the onsite structural fill (excavated material) and "bucket tamped" with the back of the CAT 330 <br />excavator bucket. All backfrll material was free of organic material, ice and snow and are considered remediated <br />as specified. <br />Q Highway 67 <br />Fill continues to be placed and compacted by method specification. A GPS dozer was observed shaping the <br />western downstream slope of the embankment. <br />11) Storm Water Management <br />Best Management Practices (BMP) are being performed. <br />Page 2 of 6 MLE2 WE 07.06.13.doc <br />
