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
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:1V. 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
