J. Bedding Fill
. 1. Bedding Filt shall be placed within the limits of the valley leach facility as shown on the
DRAWINGS and shall begin only after completion of all, or MANAGER and
CERTIFYING ENGINEER approved portion of, excavation and placement of the ore
slope regrading and end berm material in the valley leach facility.
2. CONTRACTOR shall place and compact the Bedding Fill in loose lifts such that the
compacted lift thickness is a minimum of 12-inches. CONTRACTOR shall condition
the Bedding Fill to allow a surface that does not cause rutting or other deleterious
effects. The moisture content and density shall be uniform throughout the lift. If a lift
of compacted Bedding Fill dries out during placement operations, CONTRACTOR
shall scarify, moisture condition the dry soil and recompact the lift. If a lift of
compacted Bedding Fill becomes overly wet due to precipitation or over watering,
CONTRACTOR shall allow the wet soil to dry to [he specified moisture content range
before recompaction of fill and placement of geosynthetic materials.
CONTRACTOR shall assist CQA Monitor in obtaining soil samples for CQA testing.
Bedding Fill sampling shall be scheduled by CQA Monitor with CONTRACTOR to
facilitate CQA field testing.
4. CONTRACTOR shall trim the surface of the Bedding Fill to the design grades shown
on the DRAWINGS.
5. CONTRACTOR shall roll the surface of the Bedding Fil l with a smooth drum roller to
remove ridges and surface irregularities greater than 0.5 inches in height.
CERTIFYING ENGINEER shall determine if surface preparation is sufficient to
place geomembrane. On areas with slopes steeper than 3Ha V, CONTRACTOR shat]
adopt methods as necessary to obtain the same fmai surface preparations that would be
obtained by the passage of a smooth-drum roller on flat or level ground. Pushing of
compaction equipment by tracked equipment shall no[ be performed. Wheel ruts on
the surface of the Bedding Fill ftom grading equipment shall be repaired by
CONTRACTOR prior to placement of the geomembrane by rolling the surface or
placing and compacting tailings as approved by CQA Monitor. CONTRACTOR shall
take whatever steps necessary to prepare Soil Liner Fill surface to the satisfaction of
MANAGER and CERTIFYING ENGINEER, at no additional cost to CC&V.
6. CONTRACTOR shall maintain the Bedding Fill surface in a condition suitable for
geomembrane installation as specified in these SPECIFICATIONS and in the CQA
Plan until the surface is covered. CONTRACTOR shall repay all weather related
damage to $edding Fill surfaces or other portions of the Work that have or have not
been covered by geomembrane, at no additional cost to CC&V.
If any moisture is allowed to collect under the geomembrane prior to or after fmal
seaming and softens the Bedding Fill, the geomembrane shall be removed and
CONTRACTOR shall recondition and recompact the Soil Liner Fill to meet all
placement and trimming SPECIFICATIONS, at no additional cost to CC&V.
CONTRACTOR shall remove all hubs and survey stakes in the Bedding Fill and
backfill all holes with MANAGER and CERTIFYING ENGINEER approved
material.
8. CONTRACTOR shall verify [he final thickness of Bedding Fill to determine
compliance with this SPECIFICATION. CONTRACTOR shall record as part of the
as-built documentation the location, elevation, and thickness of each Bedding Fill
verification test. CQA Monitor will witness all verification measurements. Areas with
