Newmont-Cripple Creek&Victor Gold Mine
Technical Specification No.02200 REV D
Squaw Gulch VLF ■
Project No.475.0106.006
March 13,2020
Moisture conditioning shall be adequate to achieve a uniform moisture and density. In
rock areas, the CONTRACTOR shall prepare the subgrade by removing loose rock
fragments until competent foundation material is encountered as approved by
CERTIFYING ENGINEER.
D. If the underlying material is unsuitable to permit proper compaction of the subgrade,
CONTRACTOR shall loosen, aerate (or excavate and remove), and recompact the
subgrade until the top layer can be compacted as required. The recompacted surface
shall then be scarified, as needed, to provide a good bond between the foundation and
fill materials.
3.6. Fill Placement
A. The following general guidelines shall be followed except as noted elsewhere in this
Section.
1. No fill materials shall be placed until the foundation and subgrade preparations have
been completed as specified herein, in Article 3.05 of this Section. The procedures
for fill placement shall be approved by MANAGER and CERTIFYING ENGINEER prior
to start of fill placement.
2. No brush, roots, sod, frozen material, or other deleterious or unsuitable materials
shall be incorporated in the fills. The suitability of all materials intended for use in
the fill shall be subject to approval by MANAGER and CERTIFYING ENGINEER. Fill
placement shall be temporarily stopped by CONTRACTOR due to weather conditions,
if materials and installation do not meet the SPECIFICATIONS, at no cost to CC&V. Fill
shall not be placed upon frozen material, such as snow or ice.
3. If the surface of the prepared foundation or the surface of any layer of the fill is too
dry or too smooth to bond properly with the layer of material to be placed thereon,
it shall be moisture-conditioned and/or worked with harrow, scarifier teeth, disc, or
other suitable equipment to provide a satisfactory bonding surface before fill
material is placed thereon. If the surface of the prepared foundation or the rolled
surface of any layer is excessively wet for fill materials to be placed thereon, it shall
be removed and allowed to dry or worked with a harrow, scarifier teeth, disc, or
other suitable equipment to reduce the moisture content to an acceptable level or
meet project specifications as determined by MANAGER and CERTIFYING ENGINEER.
It shall then be compacted before the next layer of fill material is placed.
Determination of such dry or wet conditions shall be made by CERTIFYING
ENGINEER.
4. The distribution of materials shall be such that the fill is free from voids, lenses,
pockets, streaks, or layers of material differing substantially in texture or gradation
from the surrounding material. The material of a fill shall be as described in Article
2.01 of this Section.
