1 when such orders are consistent with this contract, this Agreement, or the Specifications hereto attached, then the Surety on
the bond shall be notified in writing and directed to complete the work and a copy of said notice shall be delivered to the
I^ Contractor.
After receiving said notice of abandonment, the Contractor shall not remove from the work any machinery, equipment,
�.. tools, materials or supplies then on the job, but the same, together with any materials and equipment under the contract for
work, may be held for use on the work by the Owner or the Surety of the Contractor, or another contractor, in completion of
the work; and the Contractor shall not receive any rental or credit therefore (except when used in connection with Extra
Work, where credit shall be allowed as provided for under paragraph 24 of this contract); it being understood that the use of
"~ such equipment and materials will ultimately reduce the cost to complete the work and be reflected in the final settlement.
rr
F
In case the Surety should fail to commence compliance with the notice for completion hereinbefore provided for within ten
(10) days after service of such notice, then the Owner may provide for completion of the work in either of the following
elective manners:
(a) The Owner may employ such force of men and use of machinery, equipment, tools, materials and supplies as said
Owner may deem necessary to complete the work and charge the expense of such labor, machinery, equipment,
tools, materials and supplies to said Contractor, and the expense so charged shall be deducted and paid by the
Owner out of such moneys as may be due, or that may thereafter at any time become due to the Contractor under
and by virtue of this Agreement. In case such expense is less than the sum which would have been payable under
this contract, if the same had been completed by the Contractor, then said Contractor shall receive the difference.
In case such expense is greater than the sum which would have been payable under this contract, if the same had
been completed by said Contractor, then the Contractor and/or his Surety shall pay the amount of such excess to
the Owner, or
(b) The Owner, under sealed bids, after notice published as required by law, at least twice in a newspaper having a
r- general circulation in the County of location of the work, may let the contract for the completion of the work under
substantially the same terms and conditions which are provided in this contract. In case of any increase m cost to
the Owner under the new contract as compared to what would have been the cost under this contract, such increase
shall be charged to the Contractor and the Surety shall be and remain bound therefore. However, should the cost to
complete any such new contract prove to be less than that which would have been the cost to complete the work
under this contract, the Contractor or his Surety shall be credited therewith.
!^ When the work shall have been substantially completed, the Contractor and his Surety shall be so notified and certificates of
completion and acceptance, as provided in paragraph 42 hereinabove set forth, shall be is.,ued. A complete itemized
statement of the contract accounts, certified to by Owner's Representative as being correct shall then be prepared and
`., delivered to Contractor and his Surety, whereon the Contractor or his Surety, or the Owner as the case may be, shall pay the
balance due as reflected by said statement within 30 days after the date of certificate of completion.
In the event the statement of accounts shows that the cost to complete the work is less than that which would have been. the
cost to the Owner had the work been completed by the Contractor under the terms of this contract, or when the Contractor
and/or his Surety shall pay the balance shown to be due by them to the Owner, then all machinery, equipment, tools,
materials or supplies left on the site of the work shall be turned over to the Contractor and/or his Surety. Should the cost to
�.. complete the work exceed the contract price, and the Contractor and/or his Surety fail to pay the amount due the Owner
within the time designated hereinabove, and there remains any machinery, equipment, tools, materials or supplies on the
site of the work, notice thereof, together with an itemized list of such equipment and materials shall be mailed to the
Contractor and his Surety at the respective addresses designated in this contract, provided, however, that actual written
f notice given in any manner will satisfy this condition. After mailing, or other giving of such notice, such property shall be
held at the risk of the Contractor and his Surety subject only to the duty of the Owner to exercise ordinary care to protect
such property. After fifteen (15) days from the date of said notice the Owner may sell such machinery, equipment, tools,
r" materials or supplies and apply the net sum derived from such sale to the credit of the Contractor and his Surety. Such sale
may be made at either public or private sale, with or without notice, as the Owner may elect. The Owner shall release any
machinery, equipment, tools, materials, or supplies which remain on the *jobsite and belong to persons other than the
�. Contractor or his Surety, to their proper owners.
' 50. ABANDONMENT BY OWNER
In case the Owner shall fail to comply with the terms of this contract, and should fail or refuse to comply with said terms
! within ten (10) days after written notification by the Contractor, then the Contractor may suspend or wholly abandon the
work, and may remove therefrom all machinery, tools, and equipment, and all materials on the ground that have not been
�- included in payments to the Contractor and have not been incorporated into the work. Thereupon, the Owner's
a Representative shall make an estimate of the total amount earned by the Contractor, which estimate shall include the value
of all work actually completed by said Contractor at the prices stated in the the attached proposal, the value of all partially
t.. completed work at a fair and equitable price, and the amount of all Extra Work performed at the prices agreed upon, or
provided for by the terms of this contract, and a reasonable sum to cover the cost of any provisions made by the Contractor
to carry the whole work to completion, and which cannot be utilized. The Owner's Representative shall then make a final
statement of the balance due the Contractor by deducting from the above estimate all previous payments by the Owner and
'`" all other sums that may be retained by the Owner under the terms of this Agreement, and shall certify same to the Owner

PART 3 EXECUTION
3.1 PREPARATION
Before placing GCL, the Contractor shall provide written documentation
that the surfaces to receive GCL have been inspected and are acceptable
for installation of the lining. Acceptable surface conditions shall be
as described in Section 02200, Earthwork with no excessive cracking
(defined as cracks at least 1-inch in depth and 12-inches in length).
3.2 ANCHOR TRENCH
The anchor trench shall be excavated as specified prior to liner system
placement.
3.3 PLACEMENT
A. Sheets will be placed in such a manner as to reduce field seams to
a minimum.
B. The Installer shall be responsible for the following:
• No equipment or tools shall damage the GCL by handling,
trafficking, or other means.
• No personnel working on the GCL shall smoke, wear damaging
shoes, or engage in other activities that could damage the GCL.
• The method used to unroll the panels shall not cause crimps or
other damage to the GCL.
• The method used to place the panels shall minimize wrinkles.
Wrinkles shall be identified as to proper location and
compensation shall be identified on the Contractor's and
Engineer's drawings. Ballast shall be used to prevent
relocation of the compensating wrinkles by wind.
• Adequate loading (e.g., sand bags or similar items that will
not damage the GCL) shall be placed to prevent uplift by wind
(in case of high winds, continuous loading is recommended along
edges of panels to minimize risk of wind flow under the
panels).
• Direct contact with the GCL shall be minimized, i.e., the GCL
in traffic areas is protected by geotextiles, excess
geomembrane, or other suitable materials.
• No objects which would be potentially harmful to the GCL or
overlying layers remain under, within or on top of the GCL
(i.e., tools, needles, stones, etc.).
j 2745-95 02240 - 7
C. Weather Limitations
GCL placement shall not be done during any precipitation or times
of impending precipitation, when the relative humidity exceeds 80
percent, or in the presence of excessive winds, as determined by
the installation supervisor. The GCL shall not be placed in the
presence of surface moisture (e.g., dew, frost) or on ponded water.
D. Working Day Limitations
GCL placement will be limited to that amount that can be installed
and covered with geomembrane in one working day. GCL will not be
left uncovered and exposed to the elements at the end of any day.
3.4 FIELD SEAMING
A. Seam Overlap & Bentonite Filet
Seams shall be overlapped as recommended by the manufacturer.
Overlaps shall extend to the manufacturer's printed match line. A _
fillet of granular bentonite will be poured at a rate of 1/4 pound
per linear foot along the entire length of all overlap seams.
B. Seams on Slopes
Panels shall be oriented so that long edges are parallel to the
direction of maximum slope. No horizontal seams will be allowed on
slopes exceeding 7 vertical to 1 horizontal except on slopes
exceeding 190 feet in length. On slopes exceeding 190 feet in —
length, horizontal seams may only be placed within 15 feet of the
toe of slope.
3.5 SIDE SLOPES
On side slopes, the non -woven material will be placed facing down.
3.6 REPAIRS
Any necessary repairs to the GCL shall be made by placing a patch of
the same material extending at least one (1) foot beyond the flaw or
damaged area. Granular bentonite shall be added to the overlapped area
at a uniform rate of at least 1/4 pound per linear foot. Adhesive of
the type approved by the manufacturer may be used to keep patches in
place during placement of overlying materials.
3.7 LEACHA.TE COLLECTION SUMP AND DITCH LINING
Sheets shall be overlapped at least one foot at leachate collection
sumps and ditches. An extra layer of GCL material will be placed at r
the bottom of leachate collection sumps.
3.8 GCL ACCEPTANCE
The Installer shall retain all ownership and responsibility for the GCL
until acceptance by the Owner.
The GCL shall be accepted by the Owner when all of the following
conditions are met:
• Installation is finished.
• Verification of the adequacy of all field seams and repairs is
complete.

the geomembrane in traffic areas is protected by geotextiles,
extra geomembrane, or other suitable materials.
B. Weather Limitations
Geomembrane deployment shall proceed between ambient temperatures
of 32•F to 104•F. Placement can proceed below 32•F only after it
has been verified by the Engineer that the material can be seamed
according to the specification. Below 40•F, preheat of the FML
may be required.
Geomembrane placement shall not be done during any precipitation,
in the presence of excessive moisture (e.g., fog, rain, dew) or
in the presence of excessive winds, as determined by the
installation supervisor.
C. Factory Seam Quality Verifications
The Engineer will require the Contractor to test up to as much as
20% of factory fusion welds (non-destructive air pressure test
and/or vacuum test) in the field to verify factory test results.
Additional testing at the Installer's expense will be required if
failed tests are obtained in the field.
3.3 FIELD SEAMING
Seams shall be oriented parallel to the line of maximum slope, i.e.,
oriented down, not across the slope. In corners and odd -shaped
geometric locations, the number of field seams shall be minimized.
No base T-seam shall be closer than 5 feet from the toe of the slope.
Seams shall be aligned with the least possible number of wrinkles and
"fishmouths." If a fishmouth or wrinkle is found, it shall be relieved
and cap -stripped.
A. Seam Overlap
Panels of geomembrane must have a finished overlap of a minimum
of 4 inches for hot shoe fusion welding and 3 inches for extrusion
welding, but in any event sufficient overlap shall be provided to
allow peel tests to be performed on the seam. r-
2745-95 02245 - 12
L -
No solvent or adhesive may be used unless the, product is approved
by the Owners Representative. (Samples shall be submitted to the
Design Engineer for testing and evaluation).
The procedure used to temporarily bond adjacent panels together
shall not damage the geomembrane; in particular, the temperature
of hot air at the nozzle of any spot welding apparatus shall be
controlled such that the geomembrane is not damaged.
B. Seaming Equipment and Accessories
Approved equipment for field seaming are hot shoe fusion welders
and extrusion welders.
1. Hot Shoe Welder, 110 Volt, 10.Amps.
2. Extrusion Welder, 220 Volt, 19 Amps.

i 7. Field Tensiometer, capable of performing seam and peel
adhesion tests for quantitative testing on -site.
C. Test Seams
Field test seams shall be conducted on geomembrane liner to verify
that seaming conditions are satisfactory. Test seams shall be
conducted for each seamer at the beginning of each seaming period,
at the Engineer's discretion, and at least once each 4 hours, for
each seaming apparatus used that day.
All test seams shall be made at a location selected by the
Engineer in the area of the seaming and in contact with the
subgrade. The test seam samples shall be 10 feet long for hot shoe
welding and 3 feet long for extrusion welding with the seam
centered lengthwise. Specimens 1 inch wide shall be cut from each
opposite end of the test seam by the Engineer. The Engineer shall
use a tensiometer provided by the Installer to test these
specimens for shear and peel. If a test seam fails to meet field
seam specifications, the seaming apparatus and/or seamer shall not
be accepted and shall not be used for seaming until the
deficiencies are corrected and two consecutive successful full
test seams are achieved.
D. Non -Destructive Seam Testing
The Installer shall non-destructively test all field seams over
their full length. All test equipment, including but not limited
�-- to the following shall be furnished by the Installer:
j 1. Vacuum Box testing

• Clean the window, gasket surfaces and check for leaks.
• Energize the vacuum pump and reduce the tank pressure to
approximately 3-5 psi.
• Wet a strip of geomembrane approximately 12 inches by 48
inches (length of box) with the soapy solution.
• Place the box over the wetted area and compress.
• Close the bleed valve and open the vacuum valve.
• Ensure that a leak tight seal is created,
• For a period of approximately 15 seconds, examine the
geomembrane through the viewing window for the presence
of soap bubbles. --
• If no bubbles appear after 15 seconds, close the vacuum
valve and open the bleed valve, move the box over the
next adjoining area with a minimum 3 inches overlap and
repeat the process.
• All areas where soap bubbles appear shall be marked and
repaired and then retested.
The following procedures shall apply to locations where seams
cannot be non-destructively tested, as determined by the
Engineer:
If the seam is accessible to testing equipment prior to
final installation, the seam shall be non-destructively
tested prior to final installation.
• If the seam cannot be tested prior to final
installation, the seaming operations shall be observed
by the Engineer for uniformity and completeness.
2. Air Pressure Testing (For Double Fusion Seam Only)
The following procedures are applicable to those processes
which produce a double seam with an enclosed space.

• An air pump equipped with pressure gauge capable of
generating and sustaining a pressure between 25 and 30
psi and mounted on a cushion to protect the geomembrane.
• A manometer equipped with a sharp hollow needle, or
other approved pressure feed device.
The following procedures shall be followed by the Installer:
• Seal one end of the seam to be tested.
2745-95 02245 - 14
a V
Insert needle or other approved pressure feed device
through the sealed end of the channel created by the
double wedge fusion weld.
• Energize the air pump to verify the unobstructed passage
of air through the channel.
�..,0 Seal the other end of the channel.
Energize the air pump to a pressure between 25 and 30
~ psi, close valve, and sustain pressure for approximately
5 minutes.
• If loss of pressure exceeds 4 psi, or pressure does not
stabilize, locate faulty area, repair and retest.
Remove needle or other approved pressure feed device and
seal.
E. Destructive Seam Testing
The Installer shall provide the Engineer with a minimum of one
destructive test sample per 500 feet of seam length from a
location specified by the Engineer. The Installer shall not be
informed in advance of the sample location.
1. Sampling Procedure
In order to obtain test results prior to completion of liner
installation, samples shall be cut by the Installer as the
�"
seaming progresses. A destructive test must be done for each
E
welding machine used for seaming or repairs. Sampling times
and locations, shall be determined by the Engineer. The
Engineer must witness the obtainment of all field test
samples and the Installer shall mark all samples with their
t
location roll and seam number. The Installer shall also
record in written form the date, time, location, roll seam
number, ambient temperatures, and pass or fail description.
A copy of the information must be attached to each sample
portion. All holes in the geomembrane resulting from
r,
obtaining the seam samples shall be immediately repaired. All
patches shall be vacuum tested.
2. Size and Disposition of Samples
The samples shall be 12 inches wide by 36 inches long with
the seam centered lengthwise. The sample shall be cut into
two equal length pieces, and given to the Engineer.
3. Field Testing
The Installer shall cut six 1-inch wide replicate specimens
from his sample and these shall be tested by the Engineer.
The Installer shall test two specimens (four when possible
for testing both tracks on dual -track fusion welded seams)
for peel strength. All tests to be witnessed by the
Engineer. To be acceptable, both test specimens must pass.
Any specimen that fails through the weld or by adhesion at
the weldsheet interface is a Non-FTB break and shall be
considered a failure.
4. Independent Laboratory -Testing
The Engineer will package and ship all destructive seam
a samples to an independent testing Laboratory for
determination and verification of all field shear and peel
2745-95 02245 - 15
r
strengths. The test method and procedures to be used by the
Independent Laboratory shall be the same used in field
testing, where seam samples are 1 inch wide, and the grip
separation rate is 2 ipm. The minimum passing criteria for
independent laboratory testing are all three of the
following: Al• l seam samples tested in the peel mode must fail in
FTB.
• At least four of five seam samples from each peel and
shear determination must meet the minimum specified
value.
• The average value from all five seam samples from each
peel and shear determination must meet the minimum
specified value.
The above criteria apply to both tracks from each dual -track
fusion welded seam before it is considered as passing. ALL
FAILED LAB TESTS WILL BE PAID FOR BY THE INSTALLER.
5. Archive Samples
The Installer will package and ship the remaining samples to
the Engineer for archival. The samples shall include
information that indicates where the sample was taken.
6. Procedures for Destructive Test Failure
The following procedures shall apply whenever a sample fails
the field destructive test:
• The installer shall cap strip the seam between the
failed location and any passed test location.
• The installer can retrace the welding path to an
intermediate location (at a minimum of 10 feet from the
location of the failed test), at the Engineer's
discretion, and take a small sample for an additional
field test. If this test passes, then the seam shall be
cap stripped between that location and the original
failed location. If the test fails, then the process is
repeated.
• Over the length of seam failure, the Contractor shall
either cut out the old seam, reposition the panel and
reseam, or add a cap strip, as required by the Engineer.
• After reseaming or placement of the cap strip,
additional destructive field test(s) shall be taken
within the reseamed area. The reseamed sample shall be
found acceptable if test results are approved by the
Engineer. If test results are not acceptable, this
process shall be repeated until the reseamed length is
judged satisfactory by the Engineer.
In the event that a sample fails a laboratory destructive
test,- then the above procedures shall be followed,
considering laboratory tests exclusively.
The Engineer will document all actions taken in conjunction
with destructive test failures. --
2745-95 02245 - 16
F. Defects and Repairs
All seams and non -seam areas of the geomembrane shall be inspected
by the Engineer for defects, holes, blisters, undispersed raw
materials, and any sign of contamination by foreign matter.
Because light reflected by the geomembrane helps to detect
defects, the surface of the geomembrane shall be clean at the time
of inspection. The geomembrane surface shall be brushed, blown,
or washed by the Installer if the amount of dust or mud inhibits
inspection. The Engineer shall decide if cleaning of the
geomembrane is needed to facilitate inspection.
1. Evaluation
Each suspect location in seam and non -seam areas shall be
non-destructively tested as appropriate in the presence of
the Engineer. Each location that fails the non-destructive
testing shall be marked by the Engineer, and repaired
accordingly.
2. Repair Procedures
• Defective seams shall be restarted/reseamed as described
in these specifications.
• Small holes shall be repaired by extrusion cap welding.
If the hole is larger than % inch, it shall be patched.
• Tears shall be repaired by patching. Where the tear is
on a slope or an area of stress and has a sharp end it
must be rounded prior to patching.
• Blisters, large holes, undispersed raw materials, and
contamination by foreign matter shall be repaired by
patches.
• Surfaces of HDPE which are to be patched shall be
abraded and cleaned no more than 15 minutes prior to the
repair. No more than 10% of the thickness shall be
removed.
Patches shall be round or oval in shape, made of the same
geomembrane, and extend a minimum of 6 inches beyond the edge
of defects. All patches shall be of the same compound and
thickness as the geomembrane specified. All patches shall
have their top edge beveled with an angle grinder prior to
placement on the geomembrane. Patches shall be applied using
approved methods only.
3. Restart/Reseaming Procedures
The welding process shall restart by grinding the existing
seam and rewelding a new seam. Welding shall commence where
the grinding started and must overlap the previous seam by at
least 2 inches. Reseaming over an existing seam without
regrinding shall not be permitted.
k, 4. Verification of Repairs
Each repair shall be non-destructively tested, except when
-^ the Engineer requires a destructive seam sample obtained from
a repaired seam. Repairs that pass the non-destructive test
shall be taken as an indication of an adequate repair. Failed
tests indicate that the repair shall be repeated and retested
# until passing test results are achieved.
2745-95 02245 - 17
Recording of Results: daily documentation of all
non-destructive and destructive testing shall be provided to
the Engineer by the Installer. -This documentation shall
identify all seams that initially failed the test and include
evidence that these seams were repaired and successfully
retested.
3.4 GEOMEMBRANE ACCEPTANCE
The Installer shall retain all ownership and responsibility for the r
geomembrane until acceptance by the Owner. The surface of the
geomembrane shall not have striations, roughness, pinholes, or bubbles
and shall be free of holes, blisters, undispersed raw materials, or
any contamination by foreign matter; except that if in the opinion of
the Engineer the blemish will not adversely affect properties and use
of the geomembrane, the Engineer may accept the geomembrane after
sufficient laboratory test data are provided to support such
acceptance, and further, provided all such testing is done at the sole
expense of the Installer.
The geomembrane liner shall be accepted by the Owner when all of the
following conditions are met:
• Installation is finished.
• Verification of the adequacy of all field seams and repairs,
including associated testing, is complete.
• Written certification, including "as built" drawing(s), is
provided by the Installer to the Engineer.
• Documentation of completed installation, including all reports is
complete.
• Acceptance of "Flexible Membrane Liner Evaluation Report" by the
TNRCC.
