will achieve the required density, or bentonite. Areas with deficiencies shall be
• reworked by CONTRACTOR, until acceptable measurements aze obtained at no
additional cost to CC&V.
18. If tests indicate the Work does not meet the requvements of the SPECIFICATIONS,
MANAGER and CERTIFYING ENGINEER will establish the extent of the
nonconforming area. The nonconforming area shall be reworked by CONTRACTOR
until acceptable test results are obtained at no additional cost to CC& V
19. Prior to any geosynthetics being placed on Soil Liner Fill, the area will be tested by
CQA Monitor. No geosynthetics will be allowed to be placed on frozen material, as
defined in Section 3.06, without the azea in question being retested by the CQA
Monitor.
H. Drain Cover Fill
1. Drain Cover Fill shall be placed over the geomembrane in the locations shown on the
DRAWINGS.
2. Prior to placing the Drain Cover Fill, CONTRACTOR shall verify by visual inspection
that the underlying geosynthetics aze free of holes, tears, wrinkles, or foreign objects.
MANAGER and CERTIFYING ENGINEER will inspeM the geosynthetic for
wrinkles prior to placement of Drain Cover Fill. As instructed by MANAGER,
CONTRACTOR shall "work out" wrinkles to the satisfaction of MANAGER and
CERTIFYING ENGINEER prior to placement of the Drain Cover 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.
3. CONTRACTOR shall place Drain Cover Fill in a single 24-inch loose lift. The
• tracked equipment shall operate only over pzeviously-placed Drain Cover Fill.
CONTRACTOR shall no[ operate equipment directly on geosynthetics. Only a dozer
with a ground pressure not exceeding 8.7 psi can be used to place Dmin Cover Fill. A
CAT 12G motor grader, or equivalent approved by CERTIFYING ENGINEER, can
be used for Drain Cover Fill final grading. Equipment used for placement will not be
allowed to pivot on one track (i.e., no abrupt or sharp toms). There shall be no downhill
placement on slopes steeper than 4H:1 V. Material can be placed along contours if
buttressed from below. Motor graders shall not be allowed to make abrupt toms, brake
suddenly, or dig blade in which results in the tires spinning on the Drain Cover Fill
surface.
4. Highway compatible 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 Drain Cover 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 geomembtane and piping, at
no cost to CC&V. Off road haul tinck traffic shall require a minimum of 60 inches for
Cat 773 (or equivalent) of Drain Cover Fill placed over the geomembrane and solution
collection piping, and a minimum of 120 inches for CAT 777 (or equivalent) of Drain
Cover Fill placed over the geomembrane and solution collection piping.
5. When placing Drain Cover Fill the maximum acceptable drop height is 3 feet.
6. 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 instinct
CONTRACTOR to remove Drain Cover Fill to expose the geosynthetics.
