cc <br />&v <br />Amec field representative monitored structural fill material placed within the Phase I and II Squaw Gulch VLF during <br />all shifts. Average structural fill temperatures were above 32 °F <br />Tree /Slash Clearing, Chipping: <br />Seed Masters continues to "grind and chip" stockpiled trees and brush near area 34 topsoil stockpile. Equipment <br />(Seed Masters): one "Chipper", one CAT 330 Excavator <br />B) Underground Workings <br />During the reporting period exploratory excavation and remediation were performed on UG Working No. U6016, No. <br />6057, No. 6058, No. 6059, No. 6060, No 6063, No. 6066, No. 6067, No. 6069, No 6070 and No. U6071. The sites <br />were excavated to practical refusal into rock varying depths depending on the working remediated. The site for <br />each working was then backfilied in 2 foot loose lifts to approximate planned subgrade elevation using the onsite <br />structural fill (excavated material) and "bucket tamped" with the back of the CAT 330 excavator bucket. All backfill <br />material was free of organic material, ice and snow. <br />Confirmatory drilling continued on March 4th, which was performed on UG Working No. 6056, No. 6037. All drill <br />locations were spaced on 4( + / -) foot centers and drilled to specified depth. <br />No confirmatory drilling occurred due to a "drilling class" on March 5th, 6th and 7th. Drilling is expected to resume on <br />Monday March 11th. <br />Blasting occurred on UG Working No. 6004 and continues to be investigated. <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 />amec <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 />CCU V: Working with CC &V Daily updates and reporting. A weekly Project Status meeting was held at 11:00am on March 5th <br />between CC &V, CDOT, Ames and AMC. Topics discussed were Safety, Schedule, Project Issues, concerns and planning. <br />Page 2 of 6 MLE2 WE 03.09.13.doc <br />
