Topsoil Stripping:
An Amec field representative observed topsoil being removed during this reporting period in several locations within
the VLF Phase I limits. Approximately 6 inches to 2 feet were removed in various locations throughout the project
site. Several 740 articulating haul trucks transported the topsoil to the area 34 stockpile. In addition to topsoil
removal, the contractor continued to remove unsuitable materials within the limits of the PSSA. The materials were
transported to a designated stockpile with several articulating 740 haul trucks.
Structural Fill:
An Amec field representative observed the fill placement and compaction of structural fill within the Phase I Squaw
Gulch VLF and the HWY 67 embankment footprint. (See figure 1). A Cat 563 smooth drum roller was used for the
compaction efforts and a Cat D10 and a Cat D8 were utilized to push and place materials as structural fill. Structural
fill materials were placed in 18 to 24 inch lifts then compacted (Method specification applies).
In addition to structural fill placement an Amec field representative monitored structural fill material temperatures
placed within the Phase I Squaw Gulch VLF and the Hwy 67 embankment during all shifts. Average structural fill
temperatures were above 32 °F
