payments or from final payment.
It is further agreed and understood between the Contractor and Owner that time is of the essence of this contract.
�.., 35. TMM AND ORDER OF COMPLETION
It is the meaning and intent of this contract, unless otherwise herein specifically provided, that the Contractor shall be
allowed to prosecute his work at such time and sessions, in such order of precedence, and in such manner as shall be most
conductive to economy of construction; provided, however, that the order and time of prosecution shall be such that the
work shall be substantially completed as a whole and in part, in accordance with this contract, the plans and specifications,
and within the time of completion designated in the bid; provided, also, that when the Owner is having other work done,
either by contract or by his own force, the Owner's Representative may direct the time and manner of constructing work
done under this contract so that conflicts will be avoided and the construction of the various works being done for the
Owner shall be harmonized.
The Contractor shall submit, at such times as may reasonably be requested by the Owner's Representative, schedules which
shall show the order in which the Contractor intends to carry on the work, with dates at which the Contractor will start the
several parts of the work and estimated dates of completion of the several parts.
36. EXTENSION OF TIME
.. The Contractor agrees that he has submitted his bid in full recognition of the time requird for the completion of this
project, taking into consideration the average climatic range and industrial conditions prevailing in this locality, and has
considered the liquidated damage provisions of paragraph 33 hereinabove set forth and that he shall not be entitled to, nor
will he request, an extension of time on this contract, except when his work has been delayed by an act or neglect of the
Owner, Owner's Representative, employees of the Owner or other contractors employed by the owner, or by changes ordered
in the work, or by strike, walkouts, acts of God or the public enemy, fire or flood. The Contractor may apply in writing for
an extension of time, submitting therewith all written justification as may be required by Owner's Representative for such an
extension as requested by Contractor. The Owner's Representative within ten (10) days after receipt of a written request for
an extension of time by the Contractor supported by all requested documentation shall then submit such written request to
the City Council of the City of Lubbock for their consideration. Should the Contractor disagree with the action of City
Council on granting an extension of time, such disagreement shall be settled by arbitration as hereinafter provided
7.
37. HINDRANCE AND DELAYS
In executing the contract agreement, the Contractor agrees that in undertaking to complete the work within the time herein
fixed, he has taken into consideration and made allowances for all hindrances and delays incident to such work, whether
growing out of delays in securing material or workmen or otherwise. No charge shall be made by the Contractor for
hindrance or delays from any cause during the progress of any part of the work embraced in this contract except where the
work is stopped by order of the Owner or Owner's Representative for the Owner's convenience, in which event, such
expense as in the judgment of the Owner's Representative that is caused by such stoppage shall be paid by Owner to
Contractor.
38. OUANTTTIES AND MEASUREMENTS
No extra or customary measurements of any kind will be allowed, but the actual measured or computed length, area, solid
contents, number and weight only shall be considered, unless otherwise specifically provided In the event this contract is
let on a unit price basis, then Owner and Contractor agree that this contract, including the specifications, plans and other
contract documents are intended to show clearly all work to be done and material to be furnished hereunder. Where the
estimated quantities are shown for the various classes of work to be done and material to be furnished under this contract,
they are approximate and are to be used only as a basis for estimating the probable cost of the work and for comparing their
bids offered for the work. It is understood and agreed that the actual amount of work to be done and the materials to be
furnished under this contract may differ somewhat from these estimates, and that where the basis for payment under this
contract is the unit price method, payment shall be for the actual amount of work done and materials furnished on the
project.
39. PROTECTION OF ADJOINING PROPERTY
The Contractor shall take proper means to protect the adjacent or adjoining property or properties in any way encountered,
which may be injured or seriously affected by any process of construction to be undertaken under this agreement, from any
damage or injury by reason of said process of construction; and he shall be liable for any and all claims for such damage on `
account of his failure to fully protect all adjacent property. The Contractor agrees to indemnify, save and hold harmless the
Owner against any claim or claims for damages due to any injury to any adjacent or adjoining property, arising or growing
out of the performance of this contract, but such indemnity shall not apply to any claim of any kind arising out of the
existence or character of the work. k
40. PRICE FOR WORK
In consideration of the furnishing of all necessary labor, equipment and material and the completion of all work by the
Contractor, and on the delivery of all materials embraced in this contract in full conformity with the specifications and
stipulations herein contained, the Owner agrees to pay the Contractor the price set forth in the bid attached hereto, which
has been made a part of this contract, and the Contractor hereby agrees to receive such price in full for furnishing all
materials and all labor required for the aforesaid work, also, for all expenses incurred by him and for well and truly
performing the same and the whole thereof in the manner and according to this agreement, the attached specifications,
plans, contract documents and requirements of Owner's Representative.
41. PAYMENTS

wholly or in part, nor shall any certificate or payment be considered as acceptance of defective work Contractor shall at
any time requested during the progress of the work furnish the Owner or Owner's Representative with a verifying certificate
showing the Contractor's total outstanding indebtedness in connection with the work. Before final payment is made,
Contractor shall satisfy Owner, by affidavit or otherwise, that there are no outstanding liens against Owner's premises by
reason of any work under the contract. Acceptance by Contractor of final payment of the contract price shall constitute a
waiver of all claims against Owner which have not theretofore been timely filed as provided in this contract.
r
42. PARTIAL PAYMENTS

payment. Owner's Representative shall review said application for partial payment and the progress of the work made by

the total value of the work done by the Contractor up to and including the last day of the preceding month; said statement
shall also include the value of all sound materials delivered on site of the work that are to be fabricated into the work

Representative's Certificate of Partial Payment, less 5% of the amount thereof, which 5°rb shall be retained until final
payment, and further, less all previous payments and all further sums that may be retained by Owner under the terms of this
agreement. It is understood, however, that in case the whole work be near to completion, and this fact is certified to by
Owner's Representative and some unexpected and some unusual delay occurs due to no fault or negligence on the part of the
Contractor, the Owner may upon written recommendation of Owner's Representative pay a, reasonable and equitable portion
of the retained percentage due Contractor.
` ' 43. FINAL COMPLETION AND ACCEPTANCE
Within thirty-one (31) days after the Contractor has given the Owner's Representative written notice that the work has been
completed or substantially completed, the Owner's Representative and the Owner shall inspect the work and within said
time, if the work be found to be completed or substantially completed in accordance with, the contract documents, the
Owner's Representative shall issue to the Owner and Contractor his certificate of completion, and thereupon it shall be the
duty of the Owner within thirty-one (31) days to issue a certificate of acceptance of the work to the Contractor.
44. FINAL PAYMENT
Upon the issuance of the certificate of completion, the Owner's Representative shall proceed to make final measurement and
prepare a final statement of the value of all work performed and materials furnished under the terms of the agreement, and
shall certify same to the Owner, who shall pay to the Contractor on or before the 31st day after the date of certificate of
completion, the balance due Contractor under the terms of this agreement, provided he has fully performed his contractual
obligations under the terms of this contract; and said payment shall become due in any event upon said performance by the
Contractor. Neither the certificate of acceptance nor the final payment, nor any provisions in the contract documents shall
relieve the Contractor of the obligation for fulfillment of any warranty which may be regi&W in the special conditions (if
any) of this contract or required in the specifications made a part of this contract..
45. CORRECTION OF WORK BEFORE FINAL PAYMENT FOR WORK
Contractor shall promptly remove from Owners' premises all materials condemned by the Owner's Representative on
account of failure to conform to the contract, whether actually incorporated in the work or not, and Contractor shall at his
own expense promptly replace such condemned materials with other materials conforming to the requirements of the
contract. Contractor shall also bear the expense of restoring all work of other contractors damaged by any such removal or
replacement. If Contractor does not remove and replace any such condemned work within a reasonable time after a written
notice by the Owner or the Owner's Representative, Owner may remove and replace it at Contractor's expense.
46. CORRECTION OF WORK AFTER FINAL PAYMENT
Neither the final payment nor certificate nor any provision in this contract shall relieve the Contractor of responsibility for
faulty materials or workmanship, and he shall remedy any defects due thereto and pay for any damage to other work
resulting therefrom, which shall appear within a period of one (1) year from the date of substantial completion. The Owner
or the Owner's Representative shall give notice of observed defects with reasonable promptness.
47. PAYMENT WITHETELD
The Owner may, on account of subsequently discovered evidence, withhold or nullify the whole or part of any certificate to
such extent as may be necessary to protect himself from loss on account of.
(a) Defective work not remedied.
(b) Claims filed or reasonable evidence indicating possible filing of claims.
(c) Failure of the Contractor to make payments promptly to subcontractors or for materials or labor.
(d) Damage to another contractor.

protect the Owner in the amount withheld, payment shall be made for amounts withheld because of them.
48. TIME OF FILING CLAIMS
It is further agreed by both parties hereto that all questions of dispute or adjustment presented by the Contractor shall be in
writing and filed with the Owner's Representative within fifteen (15) days after the Owners Representative has given any
directions, order or instruction to which the Contractor desires to take exception. The Owners' Representative shall reply to
such written exceptions by the Contractor and render his final decision in writing. In case the Contractor should appeal
from the decision of the Owner's Representative, any demand for arbitration shall be filed with the Owner's Representative
and the Owner in writing within ten (10) days after the date of delivery to Contractor of the final decision of the Owner's
Representative. It is further agreed that final acceptance of the work by the Owner and the acceptance by the Contractor of
the final payment shall be a bar to any claim by either party, except where noted otherwise in the contract documents.
49. ABANDONMENT BY CONTRACTOR
In case the Contractor should abandon and fail or refuse to resume work within ten (10) days after written notification from
the Owner or the Owner's Representative, or if the Contractor fails to comply with the orders of the Owner's Representative,
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
Contractor.
After receiving said notice of abandonment, the Contractor shall not remove from the work any machinery, equipment, r
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.
In case the Surety should fail to commence compliance with the notice for completion herembefore 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
general circulation in the County of location of the work, may let the contract for the completion of the work under
P substantially the same terms and conditions which are provided in this contract. In case of any increase in 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
n 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 heremabove set forth, shall be issued. 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 thirty (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 tamed 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
t 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
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,
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
l 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. AANDOI ME BY OWNERBY 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
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 attached bid, the value of all partially 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 who shall pay to
the Contractor on or before thirty (30) days after the date of the notification by the Contractor the balance shown by said
final statement as due the Contractor, under the terms of this Agreement.
51. 13ONDS
The successful bidder shall be required to furnish a performance bond and payment bond in accordance with Article 5160,
Vemon's Annotated Civil Statutes in the amount of 100% of the total contract price, in the event said contract price exceeds
$25,000.00. If the contract price does not exceed $25,000.00, the statutory bonds will not be required. All bonds, if
required, shall be submitted on forms supplied by the Owner, and executed by an approved Surety Company authorized to
do business in the State of Texas. And it is further agreed that this contract shall not be in effect until such bonds are so
t
furnished

from the action of the elements, or from any unforeseen circumstance and the prosecution of the same, or from unusual
obstructions or difficulties which may be encountered in the prosecution of the work, shall be sustained and borne by the
Contractor at his own cost and expense.

Contractor is, and shall remain, an independent contractor with full, complete and exclusive power and authority to direct,
supervise, and control his own employees and to determine the method of the performance of the work covered hereby. The
fact that the Owner or Owner's Representative shall have the right to observe Contractor's work during his performance and
to carry out the other prerogatives which are expressly reserved to and vested in the Owner or Owner's Representative
hereunder, is not intended to and shall not at anytime change or effect the status of the Contractor as an independent
contractor with respect to either the Owner or Owner's Representative or to the Contractor's own employees or to any other
person, firm, or corporation.
55. CLEANING UP
The Contractor shall at all times keep the premises free from accumulation of debris caused by the work, and at the
completion of the work he shall remove all such debris and also his tools, scaffolding, and surplus materials and shall leave
the work room clean or its equivalent. The work shall be left in good order and condition. In case of dispute Owner may
remove the debris and charge the cost to the Contractor.

No horizontal seams will be allowed on slopes exceeding 7 vertical to 1 horizontal except
0 2797-95 02240 - 7
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 beep patches in place during placement

• Ens= that a leak tight seal is created.
• For a period of approximately 15 seconds, examine the geomenibrane
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 area where soap bubbles appear shall be marked and repaired and then
retested.
The following procedures shall apply to locations where scams 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 Fagineer for uniformity and completeness.
2. Air Pressure Testing (For Double Fusion Seam Only)

• Remove needle or other approved press= feed device and scat
E. Destructive Seam Testing
The installer shall provide the Engineer with a minimum of one destructive test sample
per 500 feet of scam length from a location specified by the Engineer. The Installer shaU
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 art by the installer as the seaming progresses. A destructive test must be dome
for each 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 location roll
and scam number. The Installer shall also record in written form the date, tare,
2797-95 02245 -14
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
i
geomembranc resulting from 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 scam centered
lengthwise. The sample shall be cut into two equal length pieces, and given to the
r' Engineer.
3. Field Testing
The Installer shall cut six 1-inch wide replicate specmens from his sample and
these shall be tested by the Engineer. The Installer shall test two specimens (fora
when possible for testing both tracks on dual -track fission 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 wddshect 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 samples to an independent
testing Laboratory for determination and verification of all field shear and peel
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.
• All 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 fr(m all five scam 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
S. Archive Samples
The Installer will package and ship the remaining smmmples 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 fags the field destructive
test
• The installer shall cap strip the seam between the failed iflcation and any
passed test location
• The installer can retrace the welding path to an is mmediate location (at a
minimum of 10 feet fium 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 fans, then the pa=m is repeated
a
i 2787-95 02245.15
r
• Over the length of seam failure, the Contractor shall either cut out the old
seam, reposition the panel and rmmm, or add a cap strip, as required by the
Engineer-
g or placement of the cap strip, additional destructive field
tests) shall be taken within the reseamed area. The reseamed sample shall
be found acceptable if test results ace 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.
F. Defects and Repairs
All seams and non -scam 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 Engmw shall decide if cleaning of the geomembmae is needed
to facilitate inspection.
1. Evaluation
Each suspect location in seam and non -seam area shall be non-destructively tested
as appropriate in the presence of the Engineer. Each location that fans the
non-destructive testing shall be marked by the Engineer, and repaired accordingly.
2. Repair Procedures
• Defective seams shall be restarted/reseamed as descnbcd 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 found or oval in shape, made of the same geomembrane, and
extend a minimum of 6 inch CS 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. Patch shall be applied aging 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
2797-95 02245.16
4. Verification of Repairs
Each repair shall be non-destructively tested, except when the Engineer requires a
destructive seam sample obtained from a repaired warn. Repairs that pass the
non-destructive test shalt be taken as an indication of an adequate repair. Failed
tests indicate that the repair shall be repeated and retested until passing test results
i` are achieved
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 scams
were repaired and successfidly retested.
3.4 GEOMEMBRANE ACCEPTANCE
The Installer shall retain all ownership and responsibility for the georaembrane until acceptance
by the Owner. The surface of the gemnembrane shall not have striations, roughness, pinholes,
1 ; or bubbles and shall be fire of holes, blisters, indispersed 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 fiirther, provided
all such testing is done at the sole expense of the Installer.
The geomembnme 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 bunt" drawing(s), is provided by the Installer to the
Engineer.
