A Cat dozer placed structural fill in the as -built area above C16+00. A Cat smooth drum roller
compacted the subgrade.
Cat dozers placed cut to fill between stations 111+00 and 116+00.
Cat dozers graded the slope below stations D6+00 to D10+00 and the ADR Haul Road. Cat
dozers graded the slope between stations L6+00 and L10+00. Cat dozers graded the slope
between stations DD10+00 and DD14+00.
CC&V hauled material to the Dump 4 surge in Phase 2 using Cat 793 haul trucks. A Cat D10
placed the Structural Fill between stations N20+00 and N22+00. A Cat smooth drum roller
compacted the fill area.
All of the above Structural Fill material was placed, compacted, and graded per the project plans
and specifications.
Subgrade:
A Cat smooth drum roller compacted subgrade above the tertiary underdrain between stations
A14+00 and C11+00.
Soil Liner Fill:
A John Deere excavator loaded Cat 740 haul trucks with material to be transported to the C
Bench, DD Bench, FF Bench.
Cat dozers placed SLF between stations A10+00 to A14+00, C0+00 to C6+00, E0+00 to E3+00,
E8+00 to E12+00, DD6+00 to DD12+00 and FF1+00 to FF6+00.
Cat dozers and a Cat roller finished and compacted the SLF surface upslope from stations A0+00
to A10+00.
A Cat excavator constructed a perimeter berm for Phase 1 between stations P3+00 and P10+00.
The berm was compacted with a plate tamper per project specifications.
Nuclear Density tests, N50 — N70, were completed with passing results. Depth checks, D37 —
D49, were completed with passing results.
Drain Cover Fill:
None.
Underdrain System:
Primary Underdrain: Complete.
Secondary Underdrain: None.
Tertiary Underdrain: A Cat excavator and a Cat hammer continued excavating trench
for the tertiary underdrains between stations A15+00 and A20+00 and between stations
C8+00 and C12+00. Construction of the tertiary underdrain adhered to project plans and
specifications. Approximately 800 LF of tertiary underdrain was completed.
