of passes shall be subject to CERTIFYING ENGINEER's approval, at no additional cost
to CC&V. The method SPECIFICATIONS may be changed at any time, at the discretion
of CERTIFYING ENGINEER, based upon changes in material characteristics, field
conditions, and/or compaction equipment.
D. Underdrain Fill
1. Underdrain Fill shall be placed in the Underdrains as shown in the DRAWINGS.
2. CONTRACTOR shall condition Underdrain Fill that results in a firm, unyielding surface
capable of allowing the movement of vehicles and equipment over the surface without
causing rutting or other deleterious effects.
3. CONTRACTOR shall condition, place and compact Underdrain Fill by a method
compaction technique. The compaction equipment shall consist of a minimum 10-ton
(static drum weight) vibratory smooth-drum compactor. The number of passes and loose
lift thickness shall be subject to CERTIFYING ENGINEER's approval, at no additional
cost to CC&V. The method SPECIFICATIONS may be changed at any time, at the
discretion of MANAGER, based upon changes in material characteristics, field conditions,
and/or compaction equipment.
4. Provisions shall be made by CONTRACTOR for removal of oversize materials from fills,
at no additional cost to CC&V.
5. The MANAGER will minimize the amount of traffic over the Underdrain Fill.
E. Leak Detection Fill
1. Leak Detection Fill shall be placed in the Leak Detection Trenches as shown on the
DRAWINGS.
2. CONTRACTOR shall condition Leak Detection Fill to allow a surface that does not cause
rutting or other deleterious effects.
F. Low Volume Solution Collection Fill
1. Low Volume Solution Collection Fill shall be placed over the geomembrane in the locations
shown on the DRAWINGS.
2. CONTRACTOR shall condition Low Volume Solution Collection Fill to allow a surface
that does not cause rutting or other deleterious effects.
3. CONTRACTOR shall place Low Volume Solution Collection Fill around the Low
Volume Solution Collection Vertical Riser Pipes in maximum 12-inch loose lifts and
compact using a hand operated vibratory plate compactor to the satisfaction of the
MANAGER and CERTIFYING ENGINEER. Low Volume Solution Collection Fill
shall be worked under the Low Volume Solution Collection Rise pipe haunches by hand to
provide uniform support of the pipe.
4. Prior to placing the Low Volume Solution Collection Fill, CONTRACTOR shall verify by
visual inspection that the underlying geosynthetics are free of holes, tears, wrinkles, or
foreign objects. MANAGER and CERTIFYING ENGINEER will inspect the
