Secondary Underdrain:
No work was performed on the Secondary underdrain during this reporting period.
A total of 1380 feet of underdrain has been completed.
Primary Underdrain:
An Amec field representative observed the Primary Under drain construction complete to the primary underdrain
ponds. In addition the cutoff wall was completed and installed per plans and specifications according to actual field
conditions during this reporting period.
A total of 863 feet of Primary underdrain has been completed.
Tree /Slash Clearing, Chipping:
Seed Masters began mobilizing to resume chipping process. Chipping is expected to resume during the next
reporting period.
B) Underground Workings
During the reporting period exploratory excavation was performed on UG working No. 6018, No. 6037 and No.
6051. These sites will continue with excavation into bedrock as remediation is completed as specified.
During this reporting period remediated sites were performed on UG working No. U6128, No. 6129, No. 6030, No.
U6131, No. 6037, No. 6047/U6019 No. 6049 and No. 6061. Sites listed were excavated to practical refusal into rock
varying depths depending on the working remediated. The site for each working was then backfilled in 2 foot loose
lifts to approximate planned subgrade elevation using the onsite structural fill (excavated material) and "bucket
tamped" with the back of the CAT 330 excavator bucket. All backfill material was free of organic material, ice and
snow.
Confirmatory drilling continued during the reporting period on UG Working No. 6123 and No. 6132. All drill locations
were spaced on 4( + / -) foot centers and drilled to specified depth. Exploratory excavation will continue until
remediation has been performed.
Q Highway 67
MHT #2 is in place and is working properly. No other work was performed for the existing HWY 67 crossing during
this reporting period.
11) Storm Water Management
A) Best Management Practices (BMP) are being performed. Inspections continue and there have been no
issues identified.
CQA ACTIVITIES:
i) Field Activities: Construction activities and observation of clearing and grubbing, VLF Phase I fill and compaction,
underground workings, HWY 67 embankment fill progress observation were some of the tasks performed in the field as
required per project specifications.
11) Laboratory Activities: Laboratory testing continued (Permeability, Particle Size Distribution, Atterberg Limits,
Moisture - Density, gradations and material identifications) were some of the laboratory testing performed during this
reporting period as required to project specifications.
