performed CQA laboratory testing of grain size, Atterberg limits, and
moisture content of the Underdrain Fill (UF) and SSF placed in the
Underdrains.
► Golder monitored construction of the Leak Detection Trench (LDT) and
the Leak Detection Sump (LDS), including verification that Ames
excavated the trench to minimum required dimensions and placed
materials as specified. Golder performed CQA laboratory testing of grain
size, Atterberg limits, and moisture content of the Leak Detection Fill
(LDF) placed in the LDT.
► Golder monitored site grading. Golder monitored slope reduction fill and
fill placement, including lift thickness, moisture conditioning,
temperatures, compactive effort, and use of suitable material for SF.
Golder performed CQA laboratory testing of grain size, Atterberg limits,
and moisture content of SF.
► Golder visually monitored subgrade preparation to confirm that the
subgrade surface was unyielding; free of organic matter and other
unsuitable materials, and that the subgrade surface was compacted prior to
Soil Liner Fill (SLF) placement.
► Golder visually monitored the placement and compaction of SLF including
observation of depth verification performed by Ames, particle size,
moisture conditioning, and compaction of the fill. Golder performed
in -place density and moisture content testing, and performed CQA
laboratory testing of grain size, moisture content, Atterberg limits,
compaction, and permeability. Golder also provided visual monitoring of
the SLF surface preparation and moisture conditioning for geomembrane
deployment, including verification that the surface was proof - rolled,
compacted, and hand - worked so as to be free of desiccation cracks, abrupt
grade changes, and sharp stones or objects. Golder also observed the
backfill and compaction of the anchor trenches.
► Golder visually monitored the placement of Drain Cover Fill (DCF) in the
OSA, including verification of lift thickness and grade control,
identification of deleterious materials, and verification that care was
exercised in fill placement to avoid geomembrane damage. Golder
performed CQA laboratory testing of grain size, Atterberg limits, and
moisture content of DCF.
Golder monitored the ambient air temperatures and the temperature of all
fills, including SLF, in accordance with project specifications.
