CC <br />&V <br />Amec field representative monitored structural fill material placed within the Phase 1 and II Squaw Gulch VLF during <br />all shifts. Average structural fill temperatures were above 32 °F <br />Secondary Underdrain: <br />The secondary underdrain construction continued to be installed within the lower portion of Swede gulch for the <br />Phase I Squaw gulch VLF. Approximately 830 feet of underdrain was installed per plans and specifications and is <br />expected to continue. <br />A total of 1380 feet of underdrain has been completed. <br />Tree /Slash Clearing, Chipping: <br />Seed Masters continues to "grind and chip' stockpiled trees and brush. Equipment (Seed Masters): one "Chipper", <br />one CAT 330 Excavator <br />B) Underground Workings <br />During the reporting period exploratory excavation and remediation were performed on UG Working No. 6061, No. <br />6094. The sites were excavated to practical refusal into rock varying depths depending on the working remediated. <br />The site for each working was then backfilled in 2 foot loose lifts to approximate planned subgrade elevation using <br />the onsite structural fill (excavated material) and "bucket tamped" with the back of the CAT 330 excavator bucket. <br />All backfil material was free of organic material, ice and snow. <br />Confirmatory drilling continued during the reporting period on UG Working No. 6051. All drill locations were spaced <br />on 4( +1-) foot centers and dnlled to specified depth. Exploratory excavation was performed on UG working No. <br />6112, No. 6113 and No. U6111 and will continue to be worked on until remediation has been performed. <br />C) Highway 67 <br />MHT #2 is in place and is working properly. No other work was performed for the existing HWY 67 crossing during <br />this reporting period. <br />II) Storm Water Management <br />A) Best Management Practices (BMP) are being performed. Inspections continue and there have been no <br />issues Identified. <br />CQA ACTIVITIES: <br />amecP <br />I) Field Activities: Construction activities and observation of clearing and grubbing, structural fill and compaction, <br />underground workings, HWY 67 progress observation were some of the tasks performed in the field as required to <br />project specifications.. <br />II) Laboratory Activities: Laboratory testing continued (Particle Size Distribution, Atterberg Limits, Moisture- Density, <br />gradations and material identifications) were some of the laboratory testing performed during this reporting period as <br />required to project specifications. <br />General Project Items <br />Meetings and Discussions: None at this time. <br />Summary of Concerns: None at this time <br />CC &V: Working with CC &V Daily updates and reporting. A weekly Project Status meeting was held at 11:OOam on March 19th <br />between CC &V, CDOT, Ames and Amec. Topics discussed were Safety, Schedule, Project Issues, concerns and planning. <br />Page 2 of 6 MLE2 WE 03.23.13.doc <br />
