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
geosynthetic for wrinkles prior to placement of Low Volume Solution Collection Fill. As
instructed by MANAGER, CONTRACTOR shall "work out" wrinkles to the satisfaction
of MANAGER and CERTIFYING ENGINEER prior to placement of the Low Volume
Solution Collection Fill. In all cases, wrinkles shall not be of a size that they could fold back
on themselves. Wrinkles greater than one foot shall be removed and repaired by the
INSTALLER.
5. CONTRACTOR shall place Low Volume Solution Collection Fill in a single 36 -inch loose
lift. The tracked equipment shall operate only over previously placed Low Volume Solution
Collection Fill. CONTRACTOR shall not operate equipment directly on geosynthetics.
Only a dozer with a ground pressure not exceeding 14.7 psi can be used to place Low
Volume Solution Collection Fill. Equipment used for placement will not be allowed to pivot
on one track (i.e., no abrupt or sharp turns). There shall be no downhill placement on slopes
steeper than 4H:1 V. Material can be placed along contours if buttressed from below.
6. Rubber tired construction equipment shall not be allowed to travel over the geomembrane or
on top of Solution Collection piping unless a thickness of at least 45 inches of Low Volume
Solution Collection Fill has been placed over the geomembrane and on top of Solution
Collection piping. The CONTRACTOR will be required to demonstrate to the
MANAGER, DESIGN ENGINEER and CERTIFYING ENGINEER that the equipment
and procedures used are not detrimental to the geomembrane and piping, at no cost to
CC &V. Off road haul truck traffic shall require a minimum of 60 inches for Cat 773 (or
equivalent) of Low Volume Solution Collection Fill placed over the geomembrane and
solution collection piping, and a minimum of 120 inches for CAT 777 (or equivalent) of
Low Volume Solution Collection Fill placed over the geomembrane and solution collection
piping.
7. When placing Low Volume Solution Collection Fill the maximum acceptable drop height is
3 feet.
8. CONTRACTOR shall operate equipment in a manner that is protective of underlying
geosynthetics. If MANAGER or CERTIFYING ENGINEER suspects the occurrence of
any damage to the underlying geosynthetics, MANAGER will instruct CONTRACTOR to
remove Low Volume Solution Collection Fill to expose the geosynthetics.
CONTRACTOR shall uncover, repair any observed damage of the underlying
