City Of Lubbock Landfill —

MAILED TO VENDOR: April 5, 2002
CLOSE DATE: April 11, 2002 @ 1:00 P.M.
The following items take precedence over specifications for the above named Invitation to Bid (ITB). Where any
item called for in the ITB documents is supplemented here, the original requirements, not affected by this
addendum, shall remain in effect.
Questions and concerns that surfaced prior to the prebid meeting are addressed as follows:
Question No. 1. The SLQCP is referenced throughout the project specifications, and it appears that it should have
been attached as Appendix A; however, a copy was not included in our copy of the bid documents. Can a copy be
forwarded to our attention via email, fax, or mail as soon as possible?
Response No. 1: Pertinent sections of the SLQCP are included with this addendum.
Questions No.2. In Section 02245 - 2.5.C.1 of the project specifications, it is stated that conformance testing of
the liner material shall be conducted on material delivered to the project site in accordance with the frequencies
provided in 2.5.C.2 and 2.5.C.3; however, there is no indication of who will be responsible for these costs. Later in
the specifications, 3.3.E.4, it is noted that the Engineer will be responsible for the independent destructive testing.
With that in mind, can we also assume that the Engineer will be responsible for the costs associated with the
conformance testing?
Response No. 2: No. All conformance testing that is required by the specifications on material that will be
submitted to the Engineer for approval prior to shipment to site will be the responsibility of the Contractor and/or
material supplier. Once the material is installed and destructive testing is performed by the third party QAIAC,
testing costs for those tests that pass and are approved will be the responsibility of the Owner. Any and all failed
tests during the construction phase will be the responsibility of the General Contractor who holds the contract with
the Owner.
2. The following items are resultant to the prebid meeting conducted on April 2, 2002.
A. The Bid Submittal Form has been revised to reflect unit price bidding. The REVISED BID
SUBMITTAL FORM is included herewith and must be the one submitted by the responsive bidders.
B. Regarding Specification Section 02200, EXCAVATION AND EARTHWORK. Section 1.3.A.1 and 3
refer to a geocomposite clay liner and leachate collection system. There are none of these components in this
project. Please strike any reference to a geocomposite clay liner and leachate collection system from these
specifications.
C. Where is the soil stockpile for the topsoil material that will be used as the top layer on the outside of
the berm? Topsoil will be excavated from the landfill site just west of the project site.
D. Will a SWPPP be required for the project? The landfill has a storm water plan that governs any
construction on the site. Contractor will be required to file an NOI for the project. Any plans for the NOI will be
provided by the Engineer. The only erosion control work that will be required will be an erosion fence along the
south property boundary immediately adjacent to the project area only. Cost for this fence will be incidental to the
cost of the project. Length of the erosion fence is approximately 850-linear feet.
ITB #057-02/Bmad2
ITB #057-02/BM, Addendum # 2
E. The material for the protective cover will be from the excavation material, or if any additional material
is needed from the previously excavated area located immediately adjacent and east of the project site. This
material must be processed in order to meet the project specifications for protective soil cover.
F. Any excess excavated material may be stockpiled in an area west of the project site as designated by
the Owner. There is an electrical power line easement west of the site where no material may be stockpiled.
G. Water for the project may be obtained from the water storage pond located immediately northeast of
the project. The pond is filled by line that runs in a north -south direction from the pump to the pond. The supply
line must be protected by the contractor from damage. Any damage to the line will be repaired by the Contractor
at Contractor's expense. The pump provides only 60 gpm or less. Contractor must plan accordingly. There may
be an alternative source of water, but only on an emergency basis only.
3.: Sign -in sheets from the prebid meeting are included herewith.
All requests for additional information or clarification must be submitted in writing and directed to:

3.6 Installation Procedures
Prior to installation of the FML, a site inspection will be conducted by the
Geotechnical Professional and the Contractor to verify measurements, structures
and surface conditions to support the FML.
City of Lubbock
MSWLF Permit Modifications
10-19 August 1994
Revised
I
The Contractor will provide written documentation to the Geotechnical Professional
that surfaces to receive the FML have been inspected and are acceptable for
installation of the lining.
All earth subgrade surfaces will be maintained in a smooth, uniform, and
compacted condition during installation of the lining. Excessive cracking (defined
as cracks of a least 1" in depth and at least V in length) of the surfaces will be
repaired as directed by the Geotechnical Professional. Immediately prior to
installation of the lining, any erosion or other damage to the subgrade which has
occurred since completion of earth work will be corrected. Adequate drainage of
the subgrade will be provided and maintained until installation of the lining is
completed. No vehicles will be permitted to travel the completed subgrade.
Before the work begins, the Contractor will inspect all lining materials for damage
from transit. Materials that cannot be repaired will be rejected and removed from
the work area and site.
During unwrapping of lining materials for use and placement, the Contractor will
visually inspect all materials, particularly surfaces of lining sheets, for imperfections
and faulty areas. All such defective places will be marked and repaired in
accordance with approved methods.
The FML will be installed as shown on the project plans and approved installation
drawings. Placement of the FML will be done such that good fit, without bridging,
is provided on all covers and grade changes. Excessive slack will be avoided to
minimize rippling during the soil cover operation.
Sheets of FML materials will be of such lengths and widths and will be placed in
such a manner as to reduce field seaming to a minimum. The lining will be
anchored in accordance with details shown on approved plans and drawings. The
I
' City of Lubbock 10-20 August 1994
MSWLF Permit Modifications Revised
ii
lining will be anchored and sealed to structures, pipes and other types of
,s penetrations, (if any), in accordance with details shown on approved plans and
drawings. All changes in approved installation drawings and procedures must be
approved by the Geotechnical Professional
Extreme care will be taken during installation of the lining to be certain no damage
is done to any part of the lining. Dragging of the FML material on the subgrade
will be avoided. Smoking by installation personnel will be prohibited. All handling
and installation procedures will be performed by workers wearing shoes with
smooth soles. Shoes with soles that have patterns in relief shall be prohibited.
No foot traffic will be allowed on the FML except with approved shoes. No
vehicular traffic will be allowed on the lining. All motor driven equipment using fuel
will have spark arrestors. No gasoline driven generators or cans of gas or solvent
will be placed directly on the lining material. Under no circumstances will the lining
be used as a work area to prepare patches or to store tools and supplies. If
needed, a tarpaulin of approved material will be spread out as a work area.
During installation, the Contractor will be responsible for protecting the lining
against adverse effects of high winds such as uplift. Sand bags will be used as
required to hold the lining material in position during installation. Sand bags will
be sufficiently close-knit to preclude fines from working through the bottom, sides
or seams. Paper bags, whether or not lined with plastic, will not be permitted.
Burlap bags, if used, must be lined with plastic. Bags will contain not less than 40,
nor more than 60 pounds of sand having 100 percent passing a number 8 screen
and will be tied closed after filling, using only plastic ties. Bags that are split, torn,
or otherwise losing their contents will be immediately removed from the work area
and any spills immediately cleaned up. Metal or wire ties will not be used.
The FML material will not be installed under adverse climatic conditions, unless the
Contractorcan demonstrate that his installation techniques adequately compensate
City of Lubbock 1 Q-21 August 1994
MSWLF Permit Modifications Revised
for such adverse conditions and quality of workmanship is not compromised.
Adverse climatic conditions occur when the air temperature measured 6 inches
above the FML surface is less than 320F and decreasing, or more than 90°F; when
the relative humidity is more than 80 percent; when it is raining; or when there is
frost on the ground; or during conditions of excessive winds.
FML field seams will be lap seams as shown on approved plans and drawings.
The lap seams will be formed by lapping the edges of FML sheets a minimum of
4 inches. The contact surfaces of the sheets will be wiped clean to remove dirt,
dust, moisture, and other foreign materials. For fillet weld seams, bevel edge of
FML and clean oxidation from surfaces to receive extrudate by disk grinding or
equivalent not more than one hour before seaming..
Lap seam intersections involving more than 3 thicknesses of lining material will be
avoided, and all seam intersections will be offset at least 2 FT. No horizontal field
seams will be allowed on the slope and sheets of lining material on the slopes will
extend down slope out onto bottom a minimum of b FT from toe of slope.
Field seams between sheets of FML material will be made using approved fusion
welding systems, equipment and techniques. Approved fusion welding systems
include fillet weld using extrudate, lap weld using extrudate, and lap weld using
single or double wedge welder. If the wedge welder is used, the free edge of the
seam of the top sheet will be removed without affecting the integrity of the seam.
Any necessary repairs to the FML will be made with the lining material itself, using
approved fusion welding systems, equipment and techniques. The patch size will
be 4 inches larger in all directions than the area to be patched. All corners of the
patch will be rounded with a 1 inch minimum radius.
I City of Lubbock 10-22 August 1994
MSWLF Permit Modifications Revised
All seams and seals of the FML will be tightly bonded on completion of the work.
Any lining surface showing injury due to scuffing or penetration by foreign objects
or showing distress will be replaced or repaired as directed by the Geotechnical
Professional.
Cleanup within the work area will be an ongoing responsibility of the Contractor.
Particular care will be taken to insure that no trash, tools, and other unwanted
materials are trapped beneath the lining. Care will be taken to insure that all
scraps of lining material are removed from the work area prior to completion of the
installation.
3.7 Field Quality Control
Inspection and testing will involve the full time observation of the installation of the
FML, including the making and testing of lining seams and patches and periodic
measurement of the liner material thickness to insure compliance.
Test seams will be made to verify that adequate conditions exist for field seaming
to proceed. Each .seamer will produce a test seam at the beginning of each shift
to determine the peel and tensile strength of the seam. The Geotechnical
Professional may require a sample field seam be made at any time during
seaming production to verify equipment/operator performance and seam integrity.
In addition, if a seaming operation has been suspended for more than 1/2 hour or
if a breakdown of the seaming equipment occurs, a test seam will be produced
prior to resumption of seaming operations.
1
f _
During the field seaming operation, representative, non-destructive samples will be
made forfield seams by the Contractor. These samples will be made of the same
HDPE sheet and fusion weld materials using the same installation procedures as
the FML installation itself. Samples will have a width of 12 inches plus the seam
City of Lubbock 10-23 August 1994
MSWLF Permit Modifications Revised
width and length of 36 inches. A minimum of one sample per crew each morning
and each afternoon, will be made. All field seams will have a film tear bond in
peel and shear and a minimum pounds per inch width seam strength in shear
when tested as specified in Specifications. Sample testing will be conducted by
an independent testing agency paid for by the Owner. The independent testing
agency will save all test samples including specimens tested until notified by the
Geotechnical Professional relative to their disposal. All specimens which have
failed under test will be shipped immediately by express delivery to the
Geotechnical Professional for determination of corrective measures to be taken.
During the field seaming operation, destructive samples will be removed from field
seams by the Contractor at locations selected by the Geotechnical Professional.
Repairs to the field seams will be made in accordance with repair procedures
specified in these Specifications. A minimum of one stratified sample per 500 feet
of field seam will be made. All field seams will have a film tear bond in peel and
shear and a minimum pound per inch width seam strength in shear when tested
as specified in the SLQCP. A sufficient amount of the seam must be removed in
order to conduct field testing, independent laboratory testing, and archiving of
enough material in order to retest the seam when necessary. Field testing shall
include at least two peel tests (four when possible for testing both tracks on dual -
track' fusion welded seams). Independent laboratory testing shall consist of five
shear tests and five peel tests (ten when possible for both tracks of dual -track
fusion welded seams). Destructive seam -testing locations shall be cap -stripped
and the cap completely seamed by extrusion welding to the FML. Capped
sections shall be non-destructively tested. Additional destructive test samples may
be taken if deemed necessary by the Geotechnical Professional or his
representative.
All field-tested samples from a destructive -test location must be passing in both
shear and peel for the seam to be considered as passing. The independent
i
- City of Lubbock 10-24 August 1994
MSWLF Permit Modifications Revised
laboratory testing must confirm these field results. The passing criterion for
independent laboratory testing is that four of five samples must pass in shear and
four of five must pass in peel (four of five samples from each dual track fusion
welded seam, when possible to test each seam, must be passing) before the seam
is considered as passing. The manufacturer's sheet -strength, values must be
provided.
The independent testing agency will save all test samples including specimens
tested until notified by the Geotechnical Professional relative to their disposal. All
specimens which have failed under test will be shipped immediately by express
delivery to the Geotechnical Professional for determination of corrective measures
to be taken.
All specimens tested of a field weld sample by the independent testing agency will
pass. If any specimen fails, the entire sample will be considered as a failure, and
the field weld will be rejected. In this event, the field seam(s) will be rejected as
non-conformance with the SLQCP and corrective measures will be implemented.
For nondestructive samples which have failed, corrective measures will include a
rerun of the weld test using the same sample. If the second test passes, the
Geotechnical Professional may assume an error was made in the first test and the
field seam accepted. If the second test fails, the Contractor will cap all field seams
represented by the failed sample and a new test sample submitted for retest. The
decision of the Geotechnical Professional will be final.
For destructive samples which have failed, corrective measures will include a rerun
of the weld test using the same sample. If the second test passes, the
Geotechnical Professional may assume an error was made in the first test and the
field seam accepted. If the second test fails, the Contractor will reconstruct all the
field seams between any two previous passed seam locations which include the
City of Lubbock 10-25 August 1994
MSWLF Permit Modifications Revised
failed seam or will go on both sides of the failed seam location (10 feet minimum),
take another sample each side and test both. If both pass, the Contractor will
reconstruct the field seam between.the two locations. If either fails, the Contractor
s will repeat the process of taking samples for test. In all cases, acceptable field
seams must be bounded by two passed test locations. The decision of the
Geotechnical Professional will be final.
In the event capping of a field seam is required, the Contractor will use a cover
strip of the same thickness as the lining (and from the same roll, if available) and
of 8 inches minimum width. It will be positioned over the center of the field seam
and welded to the lining using a fillet weld each side.
All FML sheets, seams, anchors, seals, and repairs will be visually inspected by
the Contractor for defects. In addition, all seams and repairs will be further
checked by a metal probe. Depending on seam welding equipment used, all
seams and repairs will be tested by a vacuum testing device, a spark testing
device and/or air pressure.
A visual inspection of the lining sheets, seams, anchors and seals will be made by
the Contractor as the installation progresses and again on completion of the
installation. Defective and questionable areas will be clearly marked and repaired.
Final approval of repairs will be given by the Geotechnical Professional.
The Contractor will run a metal probe, such as a dull -pointed ice pick, along the
length of all seams and repairs to insure that the seam is continuous and absent
of leak paths. Defects will be clearly marked and repaired.
If the fillet weld, extrusion lap weld or single hot -wedge fusion lap weld is used to
weld seams, the Contractor will further test all seams and repairs in the FML by
vacuum box. All vacuum box testing will be done in the presence of the
City of Lubbock 10-26 August 1994
MSWLF Permit Modifications Revised
Geotechnical Professional. The area to be tested will be cleaned of all dust,
i
debris, dirt and other foreign matter. A soap solution will be applied to the test
area with a paint roller and the vacuum of 10 inches Mercury (Hg) will be induced
and held at least ten seconds to mark for repair any suspicious areas as
evidenced by bubbles in the soap solution.
If the fillet weld is used to weld seams, the Contractor will further test all seams
and repairs in the FML by using a high voltage spark detector. The setting of the
detector will be 20,000 volts. In order to conduct this test, all seams to be tested
will be provided with not less than gauge 24-30 copper wires properly embedded
in the seams and grounded. All spark testing will be done in the presence of the
Geotechnical Professional. All defective areas will be marked for repair.
If the double hot -wedge is used, the Contractor will further test all seams in the
FML by using the air pressure test which consists of inserting a needle with gauge
i in the air space between welds. Air will be pumped into space to 30 psi and held
i for 5 minutes. If pressure maintains 26-30 psi, seam is acceptable. If pressure
j drops, the outside weld edge will be sprayed with a soap solution and visually
3
examined for bubbles. If no bubbles appear, the problem is with the inside weld
and the seam is acceptable. If any bubbles appear, the defect will be repaired by
extrusion welding and tested by vacuum box.
All costs of retesting of the FML including reruns of field weld tests and all repairs
will be at the Contractor's expense.
The -Contractor will retain responsibility for the integrity of the FML system until
acceptance by the Geotechnical Professional. The FML will be accepted by the
Geotechnical Professional when:
a) Written certification letters including "as built" drawings, have been received
by the Geotechnical Professional.

avoid damage to the liner system.
5.0 Protective Cover
A minimum 4-foot thick protective cover in the floor area and a minimum 2-foot thick
protective cover on the side walls will be placed above the LCS. The protective cover
may use gravels and sands with a USCS classification of GP, GW, SP, or SW. The
maximum gravel size shall not exceed two inches. Silty sands (SM) or clayey sands (SC)
may be considered if these materials can meet geotextile retention, clogging, and
permeability requirements. Pre -construction and conformance testing for the protective
cover soils will include Atterburg Limits and full gradation with a minimum conformance
testing frequency of one grain -size analysis (ASTM D422) and Att&imit (ASTM
D4318) per 5,000 cubic yards of in -place material.
1 Protective cover does not require compaction control; however, it should be stable for
construction and disposal traffic. Care will be exercised in placement so as not to shift,

wrinkle or damage the underlying geosynthetic layers, and the placement methods will
be documented. Protective cover will be placed such that the top surface, while
spreading, is a least 2 ft_above the geosynthetic layers at all times, unless low ground
I pressure dozers are used (i.e. track pressure less than 5 psi). A greater thickness will
be maintained to support loaded hauling trucks and trailers and for turning areas. Drivers
j will proceed with caution when on the overlying soil and prevent spinning of tires or sharp
turns.
Protective cover will generally be placed in an up -slope direction for sidewalls as long as
the same material is being used. Where the top few feet of sidewall (typically less than
5 feet vertically) is to be protected by a different soil type, such as clay for tying in the
final cover soil liner, this material may be place from the top, if adequate care is taken to
protect the synthetic liner components.
The required thickness of protective cover will be verified by survey methods on an
established grid system with not less than one verification point per 5,000 square feet of
surface area.
6.0 Marking and Identifying of Evaluated Areas
Red markers will be placed so that all areas for which Soil and Liner Evaluation Report
(SLER) and Flexible Membrane Liner Evaluation Report (FMLER) have been submitted
and approved by the TNRCC are readily identifiable. Such markers are to provide site
workers immediate knowledge of the extent of approved disposal areas.
Red markers will be steel or wooden posts and will extend at least six feet above ground
level. Markers will not be obscured by vegetation and will be placed so that they are not
destroyed during operations. Sufficient intermediate markers will be installed to show the
required boundary. Lost markers will be promptly replaced. Limits of the evaluated area

will be referenced to the site grid system. Markers will not be placed inside the evaluated
area.
7.0 SLER. FMLER and Construction Documentation
Upon completion of all required liner construction and evaluation, the Geotechnical
Professional will prepare and submit both the Soil Liner Evaluation Report (SLER) and
Flexible Membrane Liner Evaluation Report (FMLER) to the Commission for review and
approval. These will be submitted along with a construction documentation report.
Multiple submittals of the reports or documentation during the project may be made, if
they may facilitate review of the project by the TNRCC. The SLER and FMLER will be
signed and sealed by the Geotechnical Professional performing the evaluation and
counter -signed by the site operator or his authorized representative.
The construction documentation will contain a narrative describing the conduct of work
and testing programs required by the SLQCP, "as -built" or record drawings, and
appendices of field and laboratory data. Because the volume of data for these projects
can be quite large, the documents may be subdivided for ease of review. The preferred
document format will include the SLER, FMLER, narrative, as -built drawings, and
summaries of test results in a single volume. The remaining appendices will be placed
in accompanying volumes. SLERIFMLER submittals will include test documentation in
a form as recommended in TNRCC technical guides.
Specifically, the construction documentation report will contain or discuss the following
information, at a minimum, for geomembrane liners:
i a Roll shipment and receipt information
a Manufacturer's quality control certificates and results
■ Storage and handling information
■ Conformance test sampling and test results
■ Seamer's names and resume of experience and qualifications

MAILED TO VENDOR: April 5, 2002
CLOSE DATE: April 11, 2002 @ 1:00 P.M.
The following items take precedence over specifications for the above named Invitation to Bid (ITB). Where any
item called for in the ITB documents is supplemented here, the original requirements, not affected by this
addendum, shall remain in effect.
1. Questions and concerns that surfaced prior to the prebid meeting are addressed as follows:
Question No. 1. The SLQCP is referenced throughout the project specifications, and it appears that it should have
been attached as Appendix A; however, a copy was not included in our copy of the bid documents. Can a copy be
forwarded to our attention via email, fax, or mail as soon as possible?
Response No. 1: Pertinent sections of the SLQCP are included with this addendum.
Questions No.2. In Section 02245 - 2.5.C.1 of the project specifications, it is stated that conformance testing of
the liner material shall be conducted on material delivered to the project site in accordance with the frequencies
provided in 2.5.C.2 and 2.5.C.3; however, there is no indication of who will be responsible for these costs. Later in
the specifications, 3.3.E.4, it is noted that the Engineer will be responsible for the independent destructive testing.
With that in mind, can we also assume that the Engineer will be responsible for the costs associated with the
conformance testing?
Response No. 2:. No. All conformance testing that is required by the specifications on material that will be
submitted to the Engineer for approval prior to shipment to site will be the responsibility of the Contractor and/or
material supplier. Once the material is installed and destructive testing is performed by the third party QA/AC,
testing costs for those tests that pass and are approved will be the responsibility of the Owner. Any and all failed
tests during the construction phase will be the responsibility of the General Contractor who holds the contract with
the Owner.
2. The following Items are resultant to the prebid meeting conducted on April 2, 2002.
A. The Bid Submittal Form has been revised to reflect unit price bidding. The REVISED BID
SUBMITTAL FORM Is included herewith and must be the one submitted by the responsive bidders.
B. Regarding Specification Section 02200, EXCAVATION AND EARTHWORK. Section 1.3.A.1 and 3
refer to a geocomposite clay liner and leachate collection system. There are none of these components in this
project. Please strike any reference to a geocomposite clay liner and leachate collection system from these
specifications.
C. Where is the soil stockpile for the topsoil material that will be used as the top layer on the outside of
the berm? Topsoil will be excavated from the landfill site just west of the project site.
D. Will a SWPPP be required for the project? The landfill has a storm water plan that governs any
construction on the site. Contractor will be required to file an NOI for the project. Any plans for the NOI will be
provided by the Engineer. The only erosion control work that will be required will be an erosion fence along the
south property boundary immediately adjacent to the project area only. Cost for this fence will be incidental to the
cost of the project. Length of the erosion fence is approximately 850-linear feet.
tTB #057-02/Bmad2
1 JA;,y I
ITB #057-02BM, Addendum # 2
E. The material for the protective cover will be from the excavation material, or if any additional material
is needed from the previously excavated area located immediately adjacent and east of the project site. This
material must be processed in order to meet the project specifications for protective soil cover.
F. Any excess excavated material may be stockpiled in an area west of the project site as designated by
the Owner. There is an electrical power line easement west of the site where no material may be stockpiled.
G. Water for the project may be obtained from the water storage pond located immediately northeast of
the project. The pond is filled by line that runs in a north -south direction from the pump to the pond. The supply
line must be protected by the contractor from damage. Any damage to the line will be repaired by the Contractor
at Contractor's expense. The pump provides only 60 gpm or less. Contractor must plan accordingly. There may
be an alternative source of water, but only on an emergency basis only.
3. * Sign -in sheets from the prebid meeting are included herewith.

work required under this contract, to do the work; and agrees that whenever the Owner's Representative shall

incompetent, unfaithful, disorderly, or otherwise unacceptable to Owner or Owner's Representative, such man or
men shall be discharged from the work and shall not again be employed on the work without the Owner's
Representative's written consent.
19. CONSTRUCTION PLANT
The Contractor shall provide all labor, tools, equipment, machinery and materials necessary in the prosecution and
completion of this contract where it is not otherwise specifically provided that Owner shall furnish same, and it is
also understood that Owner shall not be held responsible for the care, preservation, conservation, or protection of
any materials, tools, equipment or machinery or any part of the work until it is finally completed and accepted.
The building of structures for the housing of men or equipment will be permitted only at such places as the
Owner's Representative shall consent or direct, and the sanitary conditions of the grounds in or about such
structure shall at all times be maintained in a manner satisfactory to the Owner's Representative.

approved by the Owner's Representative and their use shall be strictly enforced.
21. OBSERVATION AND TESTING
The Owner or Owner's Representative shall have the right at all times to observe and test the work. Contractor
shall make necessary arrangements and provide proper facilities and access for such observation and testing at
any location wherever such work is in preparation or progress. Contractor shall ascertain the scope of any
observation that may be contemplated by Owner or Owner's Representative and shall give ample notice as to the
time each part of the work will be ready for such observation. Owner or Owner's Representative may reject any
such work found to be defective or not in accordance with the contract documents, regardless of the stage of its
completion or the time or place of discovery of such errors and regardless of whether Owner's Representative has
previously accepted the work through oversight or otherwise. If any such work should be covered without approval
or consent of the Owner, it must, if requested by Owner or Owner's Representative, be uncovered for examination
at Contractor's expense. In the event that any part of the work is being fabricated or manufactured at a location
where it is not convenient for Owner or Owner's Representative to make observations of such work or require
testing of said work, then in such event Owner or Owner's Representative may require Contractor to furnish
Owner or Owner's Representative certificates of inspection, testing or approval made by persons competent to
perform such tasks at the location where that part of the work is being manufactured or fabricated. All such tests
will be in accordance with the methods prescribed by the American Society for Testing and Materials or such other
applicable organization as may be required by law or the contract documents.
If any such work which is required to be inspected, tested, or approved is covered up without written approval or
consent of the Owner or Owner's Representative, it must, if requested by the Owner or Owner's Representative,
be uncovered for observation and testing at the Contractor's expense. The cost of all such inspections, tests and
approvals shall be borne by the Contractor unless otherwise provided herein. Any work which fails to meet the
requirements of any such tests, inspections or approvals, and any work which meets the requirements of any such
tests or approvals but does not meet the requirements of the contract documents shall be considered defective,
and shall be corrected at the Contractor's expense.
Neither observations by the Owner or Owner's Representative, nor inspections, tests, or approvals made by
Owner, Owner's Representative, or other persons authorized under the contract documents to make such
inspections, tests, or approvals shall relieve the Contractor from its obligation to perform the work in accordance
with the requirements of the contract documents.
22. DEFECTS AND THEIR REMEDIES
It is expressly agreed that if the work or any part thereof, or any material brought on the site of the work for use in
the work or selected for the same, shall be deemed by the Owner or Owner's Representative as unsuitable or not
in conformity with plans, specifications and/or contract documents, the Contractor shall, after receipt of written
notice thereof from the Owner's Representative, forthwith remove such material and rebuild or otherwise remedy
such work so that it shall be in full accordance with the contract documents. It is further agreed that any remedial
action contemplated as hereinabove set forth shall be at Contractor's expense.

The Contractor further agrees that the Owner may make such changes and alterations as the Owner may see fit,
in the line, grade, form dimensions, plans or materials for the work herein contemplated, or any part thereof, either
before or after the beginning of the construction, without affecting the validity of this contract and the
accompanying bond.
If such changes or alterations diminish the quantity of the work to be done, they shall not constitute the basis for a
claim for damages, or anticipated profits on the work that may be dispensed with. If they increase the amount of
work, and the increased work can fairly be classified under the specifications, such increase shall be paid
according to the quantity actually done and at the unit price established for such work under this contract;
otherwise such additional work shall be paid for as provided under Extra Work. In case the Owner shall make
such changes or alterations as shall make useless any work already done or material already furnished or used in
said work, then the Owner shall recompense the Contractor for any material or labor so used, and for actual
expenses incurred in preparation for the work as originally planned.
24. EXTRA WORK
The term "extra work" as used in this contract shall be understood to mean and include all work that may be
required by the Owner or Owner's Representative to be done by the Contractor to accomplish any change,
alteration or addition to the work as shown on the plans and specifications or contract documents and not covered
by Contractor's bid, except as provided under Changes and Alterations herein.
It is agreed that the Contractor shall perform all extra work under the direction of the Owner's Representative
when presented with a written work order signed by the Owner's Representative; subject, however, to the right of
the Contractor to require written confirmation of such extra work order by the Owner. It is also agreed that the
compensation to be paid to the Contractor for performing said extra work shall be determined by the following
methods:
Method (A) - By agreed unit prices; or
Method (B) - By agreed lump sum; or
Method (C) - If neither Method (A) or Method (B) be agreed upon before the extra work is commenced,
then the Contractor shall be paid the lesser of the following: (1) actual field cost of the
extra work, plus fifteen (15%) percent; or (2) the amount that would have been charged by
a reasonable and prudent Contractor as a reasonable and necessary cost for
performance of the extra work.
In the event said extra work be performed and paid for under Method (C)(1), then the provisions of this paragraph
shall apply and the "actual field cost" is hereby defined to include the cost of all workmen, such as foremen,
timekeepers, mechanics and laborers, materials, supplies, teams, trucks, rentals on machinery and equipment, for
the time actually employed or used on such extra work, plus actual transportation charges necessarily incurred,
i together with all expenses incurred directly on account of such extra work, including Social Security, Old Age
Benefits, Maintenance Bonds, Public Liability and Property Damage and Workers' Compensation and all other
insurances as may be required by law or ordinances or directed by the Owner or Owner's Representative, or by
them agreed to. Owner's Representative may direct the form in which accounts of the actual field cost shall be
kept and records of these accounts shall be made available to the Owner's Representative. The Owner's
Representative may also specify in writing, before the work commences, the method of doing the work and the
type and kind of machinery and equipment to be used; otherwise, these matters shall be determined by the
Contractor. Unless otherwise agreed upon, the prices for the use of machinery and equipment shall be
determined by using 100%, unless otherwise specified, of the latest Schedule of Equipment and Ownership
Expenses adopted by the Associated General Contractors of America. Where practical, the terms and prices for
the use of machinery and equipment shall be incorporated in the written extra work order. The fifteen percent
(15%) of the actual field cost to be paid to Contractor shall cover and compensate Contractor for its profit,
overhead, general superintendence and field office expense, and all other elements of cost and expense not
embraced within the actual field cost as herein defined, save that where the Contractor's Camp or Field Office
must be maintained primarily on account of such Extra Work, then the cost to maintain and operate the same shall
be included in the "actual field cost."
No claim for extra work of any kind will be allowed unless ordered in writing by Owner's Representative. In case
any orders or instructions appear to the Contractor to involve extra work for which Contractor should receive
compensation or an adjustment in the construction time, Contractor shall prior to commencement of such extra
work, make written request to the Owner's Representative for a written order authorizing such extra work. Should
a difference of opinion arise as to what does or does not constitute extra work or as to the payment therefore, and
the Owner's Representative insists upon its performance, the Contractor shall proceed with the work after making
written request for written order and shall keep adequate and accurate account of the actual field cost thereof, as
provided under Method (C)(1). If Contractor does not notify Owner's Representative before the commencement of
any extra work, any claim for payment due to alleged extra work shall be deemed waived.
25. DISCREPANCIES AND OMISSIONS
It is further agreed that it is the intent of the contract documents that all work described in the bid, the
specifications, plans and other contract documents, is to be done for the prices quoted by the Contractor and that
such price shall include all appurtenances necessary to complete the work in accordance with the intent of these
contract documents as interpreted by Owner's Representative. Notices of any discrepancies or omissions in
these plans, specifications, or contract documents, shall be given to the Owners' Representative and a
clarification obtained before the bids are received, and if no such notice is received by the Owner's
Representative prior to the opening of bids, then it shall be deemed that the Contractor fully understands
the work to be included and has provided sufficient sums in its bid to complete the work in accordance
with these plans and specifications. If Contractor does not notify Owner's Representative before bidding
of any discrepancies or omissions, then it shall be deemed for all purposes that the plans and
specifications are sufficient and adequate for completion of the project. It is further agreed that any
request for clarification must be submitted no later than five (5) calendar days prior to the opening of
bids.
26. RIGHT OF OWNER TO MODIFY METHODS AND EQUIPMENT
If at any time the methods or equipment used by the Contractor are found to be inadequate to secure the quality of
work with the rate of progress required under this contract, the Owner or Owner's Representative may order the
Contractor in writing to increase their safety or improve their character and efficiency and the Contractor shall
comply with such order.
If, at any time, the working force of the Contractor is inadequate for securing the progress herein specified, the
Contractor shall, if so ordered in writing, increase its force or equipment, or both, to such an extent as to give
reasonable assurance of compliance with the schedule of progress.

then the Contractor does hereby agree as part of the consideration for the awarding of this contract, the Owner
may withhold permanently from Contractor's total compensation, the sum of $150.00 (ONE HUNDRED FIFTY)
PER DAY, not as a penalty, but as liquidated damages for the breach of the contract as herein set forth for each
and every working day that the Contractor shall be in default after the time stipulated for substantially completing
the work.
It is expressly understood and agreed, by and between Contractor and the Owner, that the time for the substantial
completion of the work described herein is reasonable time for the completion of the same, taking into
consideration the average climatic range and conditions and usual industrial conditions prevailing in this locality.
The amount is fixed and agreed upon by and between the Contractor and the Owner because the actual damages
the Owner would sustain in such event would be difficult and/or impossible to estimate, however, the amount
agreed upon herein is a reasonable forecast of the amount necessary to render just compensation to Owner, and
is expressly agreed to be not disproportionate to actual damages as measured at time of breach.
IT IS FURTHER AGREED AND UNDERSTOOD BETWEEN THE CONTRACTOR AND OWNER THAT TIME IS
OF THE ESSENCE OF THIS CONTRACT.
13
35. TIME 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 its 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 its 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. TIME OF PERFORMANCE
The Contractor agrees that it has submitted its bid in full recognition of the time required 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 34 hereinabove set forth and expressly agrees that
it shall not be entitled to, nor will it request, an extension of time on this contract, except when its 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. Any request for extension shall be in writing with the written request for same setting forth all
justifications, in detail, for the request, and submitted to Owner's Representative within twenty (20) calendar days
of the occurrence of the event causing said delay. A failure by Owner's Representative to affirmatively grant the
extension no later than twenty (20) calendar days of written submission by Contractor shall be deemed a denial,
and final. Further, in the absence of timely written notification of such delay and request for extension, as provided
herein, any request for extension by Contractor shall be deemed waived.
37. HINDRANCE AND DELAYS
In executing the contract, the Contractor agrees that in undertaking to complete the work within the time herein
fixed, Contractor has taken into consideration and made allowances for all hindrances and delays incident to such
work, whether growing out of delays due to unusual and unanticipated circumstances, difficulties or delays in
securing material or workmen, or any other cause or occurrence. 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 sole judgment of the Owner's Representative that is caused by such
stoppage shall be paid by Owner to Contractor.
38. QUANTITIES 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, and only when same are expressly stated
to be estimates, 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. In the event the amount of work to be done and materials to be furnished are
expressly stated to be estimated, and only when same are expressly stated to be estimated, 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.
14
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 Contractor shall be
liable for any and all claims for such damage on account of his failure to fully protect all adjacent property. Without
limiting, in any way, manner and form, the indemnity provided by Contractor in paragraph 27 hereof, the
Contractor agrees to indemnify, save and hold harmless the Owner, and any of its officers, agents and employees,
against any and all claims or damages due to any injury to any adjacent or adjoining property, related to, arising
from or growing out of the performance of this contract.
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 proposal 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 Contractor 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
No payments made or certificates given shall be considered as conclusive evidence of the performance of the
contract, either 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, Owner's
agents and employees, which have not theretofore been timely filed as provided in this contract.
42. PARTIAL PAYMENTS
On or before the tenth day of each month, the Contractor shall submit to Owner's Representative an application
for partial payment or, if the Contractor does not submit such application, the Owner's Representative shall
determine the amount to be partially paid. Owner's Representative shall review said application for partial
payment if submitted, and the progress of the work made by the Contractor and if found to be in order, shall
prepare a certificate for partial payment showing as completely as practical the total value of the work done by the
Contractor up to and including the last day of the preceding month. The determination of the partial payment by
the Owner's Representative shall be in accordance with Paragraph 14 hereof.
The Owner shall then pay the Contractor on or before the fifteenth day of the current month the total amount of the
Owner's Representative's Certificate of Partial Payment, less 5% of the amount thereof, which 5% 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 the contract documents.
Any partial payment made hereunder shall not constitute a waiver by the Owner of any and all other rights to
enforce the express terms of the contract documents, and all remedies provided therein, as to any and all work
performed, to be performed and/or materials delivered hereunder, including, but limited to, work to which said
partial payment is attributable.
43. SUBSTANTIAL COMPLETION
Contractor shall give Owners Representative written notice of substantial completion. Within thirty-one (31)
working days after the Contractor has given the Owner's Representative written notice that the work has been
15
substantially completed, the Owner's Representative and/or the Owner shall inspect the work and within said time,
if the work be found to be substantially completed in accordance with the contract documents, the Owner's
Representative shall issue to the Owner and Contractor a certificate of substantial completion. Notwithstanding
the issuance of a certificate of substantial completion, Contractor shall proceed with diligence to finally complete
the work within the time provided in this contract.
44. FINAL COMPLETION AND PAYMENT
The Contractor shall give written notice to Owner's Representative of final completion. Upon written notice of final
completion, the Owner's Representative shall proceed to make final measurement to determine whether final
completion has occurred. If the Owner's Representative determines final completion has occurred, Owner's
Representative shall so certify to the Owner. Upon certification by Owner's Representative of final completion,
Owner shall pay to the Contractor on or before the 31 st working day after the date of certification of final
completion, the balance due Contractor under the terms of this agreement. Neither the certification of final
completion 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 required in the contract documents and/or any warranty or
warranties implied by law or otherwise.
45. CORRECTION OF WORK
Contractor shall promptly remove from Owner's premises all materials condemned by the Owner's Representative
on account of failure to conform to the contract documents, whether actually incorporated in the work or not, and
Contractor shall at its own expense promptly replace such condemned materials with other materials conforming
to the requirements of the contract documents. 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.
Neither the final payment, nor certification of final completion or substantial completion, nor any provision in the
contract documents shall relieve the Contractor of responsibility for faulty materials or workmanship, and
Contractor 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 certification of final completion by Owner's
Representative.
46. PAYMENT WITHHELD
The Owner or Owner's Representative may, on account of subsequently discovered evidence, withhold or nullify
the whole or part of any certification to such extent as may be necessary to protect itself from loss on account of:
(a) Defective work not remedied and/or work not performed.
(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.
When the above grounds are removed, or the Contractor provides a surety bond satisfactory to the Owner, in the
amount withheld, payment shall be made for amounts withheld because of them.
47. CLAIM OR DISPUTE
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) calendar days after the Owner's
Representative has given any direction, order or instruction to which the Contractor desires to take exception.
Timely written notice of dispute as provided in this contract of any decision by Owner's Representative or Owner
shall be a condition precedent to the bringing and/or assertion of any action or claim by Contractor of any right
under this Contract. If the matters set forth in the notice of dispute are not granted or otherwise responded to by
Owner's Representative within fifteen (15) calendar days of receipt of notice of dispute by Owner's Representative,
said objections shall be deemed denied. Any decision by the Owner's Representative, or deemed denial by the
Owner's Representative, shall be final and conclusive in the absence of fraud. It is further agreed that the
16
acceptance by the Contractor of the final payment shall be a bar to any and all claims of the Contractor, and
constitute a waiver of the right to assert any claim against Owner, Owner's agents and employees and Owner's
Representative, by Contractor.
48. NON-COMPLIANCE AND/OR ABANDONMENT BY CONTRACTOR
In case the Contractor should (1) abandon and fail or refuse to resume work within fifteen (15) calendar days after
written notification from the Owner or the Owner's Representative, or (2) if the Contractor fails to comply with the
written orders of the Owner's Representative, when such orders are consistent with this contract, then the Surety
on the bond shall be noted in writing and directed to complete the work and a copy of said notice shall be
delivered to the Contractor. In the event a bond is not required by law, or otherwise obtained by the Contractor, no
further notice of such non-compliance to Contractor shall be required.
After receiving said notice of abandonment or non-compliance, 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.
In the event the Contractor, or Surety, whichever is applicable, should fail to commence compliance with the notice
hereinbefore provided within ten (10) calendar days after service of such notice, and/or shall fail to proceed with
diligence to complete the project as contemplated and in compliance with all terms and provisions of the contract
documents, then the Owner may exercise any and all remedies available to it pursuant to law, contract, equity or
otherwise, including, but not limited to, providing 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. Incase 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 its 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 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. 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.
In the event the Owner's Representative elects to complete the work, as described above, when the work shall
have been finally completed, the Contractor and his Surety shall be so notified and certification of completion as
provided in paragraph 44 hereinabove 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, if applicable, 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 certification of completion.
In the event the statement of accounts shows that the cost to complete the work is less than that which would
J 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, if applicable, 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 tumed over
17
to the Contractor and/or his Surety, if applicable. Should the cost to complete the work exceed the contract price,
and the Contractor and/or his Surety, if applicable, 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, if applicable, 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, if applicable, subject only to the duty of the
Owner to exercise ordinary care to protect such property. After fifteen (15) calendar 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, if applicable. 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 that remain on the jobsite and belong to persons other than the Contractor
or his Surety, if applicable, to their proper owners.
The remedies provided to Owner by law, equity, contract, or otherwise, shall be cumulative, to the extent permitted
by law. It is expressly agreed and understood that the exercise by Owner of the remedies provided in this
paragraph shall not constitute an election of remedies on the part of Owner, and Owner, irrespective of its
exercise of remedies hereunder, shall be entitled to exercise concurrently or otherwise, any and all other remedies
available to it, by law, equity, contract or otherwise, including but not limited to, liquidated damages, as provided in
paragraph 34, hereinabove set forth.
49. LIMITATION ON CONTRACTOR'S REMEDY
The remedies of Contractor hereunder shall be limited to, and Owner shall be liable only for, work actually
performed by Contractor and/or its subcontractors as set forth in the contract documents, and Owner shall not be
liable for any consequential, punitive or indirect loss or damage that Contractor may suffer in connection with the
project which is the subject matter of this contract.
50. BONDS
The Contractor is required to furnish a performance bond in accordance with Chapter 2253, Government Code, in
the amount of 100% of the total contract price in the event that said contract price exceeds $100,000 and the
Contractor is required to furnish a payment bond in accordance with Chapter 2253, Government Code, in the
amount of 100% of the total contract price in the event that said contract price exceeds $25,000. All bonds 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. It is further agreed that this contract shall not be in effect until such bonds are so
furnished.
51. SPECIAL CONDITIONS
In the event special conditions are contained herein as part of the contract documents and said special conditions
conflict with any of the general conditions contained in this contract, then in such event the special conditions shall
control.
52. LOSS OR EXPENSE DUE TO UNUSUAL OR UNANTICIPATED CIRCUMSTANCES
Unless otherwise specified herein, all loss, expense or damage to the Contractor arising out of the nature of the
work to be done, or from the action of the elements, or from any unforeseen circumstance or from unusual
obstructions or difficulties, naturally occurring, man made or otherwise, which may be encountered in the
prosecution of the work, shall be sustained and borne by the Contractor at his own cost and expense.
53. INDEPENDENT CONTRACTOR
Contractor is, and shall remain, an independent contractor with full, complete and exclusive power and authority to
direct, supervise, and control its 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 Contractor's 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 any time change or
18
_I
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.
i 54. CLEANING UP
i
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 Contractor shall remove all such debris and also its 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.
55. HAZARDOUS SUBSTANCES AND ASBESTOS
Hazardous Substances (herein so called), as defined in the Comprehensive Environmental Response,
Compensation, and Liability Act (42 U.S.C.S. §9601(14)) and the regulations promulgated thereunder, as same
may be amended from time to time, hydrocarbons or other petroleum products or byproducts and/or asbestos, in
any form, shall not (i) be utilized, in any way, manner or form, in the construction of, or incorporation into, the
Project; or (ii) be brought upon, placed, or located, by any party, on the Project site, or any other property of the
City, without the written consent of the Owner's Representative. If Contractor believes that the utilization of a
Hazardous Substance, hydrocarbons or other petroleum products or byproducts and/or asbestos is necessary in
the construction of the Project, or that it is necessary to place and/or otherwise locate upon the site of the Project
or other property of the City, a Hazardous Substance, hydrocarbons or other petroleum products or byproducts
and/or asbestos, Contractor shall notify the Owner's Representative, and request consent therefrom, at least
twenty (20) days prior to such action. Owner's Representative may grant or deny the request of Contractor and
provide whatever requirements such consent, if granted, is conditioned upon, in its sole and absolute discretion. If
the request of Contractor is not granted, or otherwise not responded to, by Owner's Representative within five (5)
days of the receipt of said request, said request shall be deemed to be denied.
In the event Owner's Representative shall consent to the request of Contractor, Contractor shall be responsible for
ensuring that all personnel involved in the Project are (i) trained for the level of expertise required for proper
performance of the actions contemplated by this Contract and, in particular, in all aspects of handling, storage,
disposal and exposure of Hazardous Substances, hydrocarbons or other petroleum products or byproducts and/or
asbestos; and (ii) are provided and utilize all protective equipment, including without limitation, personal protective
gear, necessary to provide protection from exposure to Hazardous Substances, hydrocarbons or other petroleum
products or byproducts and/or asbestos.

period, at the Engineer's discretion, and at least once each 4 hours, for each seaming apparatus used
1 that day.
All test seams shall be made at a location selected by the Engineer in the area of the seaming and
ij 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
)I
01248001 GEOMEMBRANE LINER 02245 - 11
02/02
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

box) with the soapy solution.
5)
Place the box over the wetted area and compress.
6)
Close the bleed valve and open the vacuum valve.
7)
Ensure that a leak tight seal is created.
8)
For a period of approximately 15 seconds, examine the geomembrane through
the viewing window for the presence of soap bubbles.
9)
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.
10)
All areas where soap bubbles appear shall be marked and repaired and then
retested.
C. The
following procedures shall apply to locations where seams cannot be
non-destructively tested, as determined by the Engineer:
1)
If the seam is accessible to testing equipment prior to final installation, the seam
shall be non-destructively tested prior to final installation.

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:
a. All seam samples tested in the peel mode must fail in FTB.
b. At least four of five seam samples from each peel and shear determination must meet
the minimum specified value.
C. 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
a. The following procedures shall apply whenever a sample fails the field destructive test:
1) The installer shall cap strip the seam between the failed location and any passed
test location.
2) 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.
3) 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.
4) 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.
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
a. Defective seams shall be restarted/reseamed as described in these specifications.
b. Small holes shall be repaired by extrusion cap welding. If the hole is larger than 3 inch,
it shall be patched.
C. 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.
d. Blisters, large holes, undispersed raw materials, and contamination by foreign matter
shall be repaired by patches.
e. 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.
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.
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 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:
1. Installation is finished.
2. Verification of the adequacy of all field seams and repairs, including associated testing, is
complete.
3. Written certification, including "as built" drawing(s), is provided by the Installer to the
Engineer.
4. Documentation of completed installation, including all reports is complete.
5. Acceptance of "Flexible Membrane Liner Evaluation Report" by the TNRCC.
