SECTION 00 43 37
VENDOR COMPLIANCE TO STATE LAW NON RESIDENT BIDDER
Texas Government Code Chapter 2252 was adopted for the award of contracts to nonresident bidders. This law
provides that, in order to be awarded a contract as low bidder, nonresident bidders (out-of-state contractors
whose corporate offices or principal place of business are outside the State of Texas) bid projects for construction,
improvements, supplies or services in Texas at an amount lower than the lowest Texas resident bidder by the
same amount that a Texas resident bidder would be required to underbid a nonresident bidder in order to obtain a
comparable contract in the State which the nonresident's principal place of business is located.
The appropriate blanks in Section A must be filled out by all nonresident bidders in order for your bid to meet
specifications. The failure of nonresident bidders to do so will automatically disqualify that bidder. Resident bidders
must check the box in Section B.
A. Nonresident bidders in the State of :State Here or Blank" , our principal place of business,
are required to be % Here percent lower than resident bidders by State Law. A copy of the
statute is attached.
Nonresident bidders in the State of State Here or Blank , our principal place of business,
are not required to underbid resident bidders.
B. The principal place of business of our company or our parent company or majority owner is
in the State of Texas.

perform and proceeds diligently to cure such failure within no more than 30 days of receipt of
said notice.
D. Where Contractor's services have been so terminated by City, the termination will not affect any
rights or remedies of City against Contractor then existing or which may thereafter accrue. Any
retention or payment of moneys due Contractor by City will not release Contractor from liability.

1. Pavement temperatures are estimated from air temperatures using an algorithm contained in a Department -supplied computer program, may be provided by the Department, or by following the procedures
outlined in AASHTO MP 2 and PP 28.
2. This requirement may be waived at the Department's discretion if the supplier warrants that the asphalt binder can be adequately pumped, mixed, and compacted at temperatures that meet all applicable
safety, environmental, and consiructability requirements. At test temperatures where the binder is a Newtonian fluid, any suitable standard means of viscosity measurementmay be used, including capillary
(T 201 or T 202) or rotational viscometry (T 316).
3. Viscosity at 135°C is an indicator of mixing and compaction temperatures that can be expected in the lab and field. High values may indicate high mixing and compaction temperatures. Additionally,
significant variation can occur from batch to batch. Contractors should be aware that variation could significantly impact their mixing and compaction operations. Contractors are therefore responsible for
addressing any constructability issues that may arise.
4. For quality control of unmodified asphalt binder production, measurement of the viscosity of the original asphalt binder may be substituted for dynamic shear measurements of G*/sin(d) at test
temperatures where the asphalt is a Newtonian fluid. Any suitable standard means of viscosity measurement may be used, including capillary (T 201 or T 202) or rotational viscometry (T 316).
5. Silicone beam molds, as described in AASHTO TP 1-93, are acceptable for use.
6. If creep stiffness is below 300 MPa, direct tension test is not required. If creep stiffness is between 300 and 600 MPa, the direct tension failure strain requirement can be used instead of the creep stiffness
requirement. The m-value requirement must be satisfied in both cases.

FORT WORTH, TEXAS
1.0 INTRODUCTION
1.1 PROJECT DESCRIPTION
Pavement reconstruction with the same pavement width is to occur along five residential
streets in Fort Worth, Texas as detailed below.
• Beddell —1330 LF
• Bewick - 760 LF
• Flint — 360 LF
• Wayside — 650 LF
• Willing —1940 LF
Pavement design was performed per the current City of Fort Worth Pavement Design
Standards Manual with the exception that only typical testing needed for pavement design
was performed as detailed below. Proctor compaction, UU Triaxial tests and CBR tests
were not performed. CBR correlations were based on soil strength, swell and index
properties.
1.2 PURPOSE AND SCOPE
The purposes of this geotechnical investigation were to: 1) explore the subsurface
conditions at the site, 2) provide boring logs that present subsurface conditions encountered
including water level observations and laboratory test results, 3) provide thickness
measurements of the existing pavements at the core locations, and 4) provide subgrade and
pavement recommendations for roadway reconstruction. This investigation was performed in
accordance with our Proposal No. P09-0302E dated March 10, 2009.
2.0 FIELD INVESTIGATION
The field investigation consisted of drilling eighteen (18) test borings at locations shown on
Figures 1 through 1d. The test borings were advanced to depths of 10 feet. Prior to drilling,
the existing pavement was cored.
A coring machine with a diamond core barrel was used to core the existing pavements. A
truck -mounted drilling rig was used to advance the borings and to obtain samples for
MAS-TEK ENGINEERING & ASSOCIATES
E09-1205
PAGE 1
laboratory evaluation. The boring locations were located at the approximate locations shown
on the Boring location plans (Figures 1 through 1d).
Undisturbed samples of cohesive soils were obtained at intermittent intervals with standard,
thin -walled, seamless tube samplers. These samples were extruded in the field, logged,
sealed, and packaged to protect them from disturbance and maintain their in -situ moisture
content during transportation to our laboratory. Rock hardness was evaluated by cone
penetration tests. The test borings were backfilled and the pavement patched immediately
with concrete upon completion of the borings.
The results of the boring program are presented on the Logs of Borings, Figures 2 through
19. A key to the descriptive terms and symbols used on the logs is presented on Figure 20.
3.0 LABORATORY TESTING
Laboratory tests were performed on representative samples of the soil to aid in classification
of the soil materials. These tests included Atterberg limits tests and moisture content tests.
Hand penetrometer tests were performed on the clay soil samples to provide indications of
the swell potential and the foundation bearing properties of the subsurface strata. The
results of these tests are presented on the Logs of Borings (Figures 2 through 19).
The results of swell tests performed on representative samples of the clay soils at this site
are shown on Figure 21. Lime Series and Soluble Sulfate tests were also performed on
selected samples (see Figures 22 and 23).
4.0 SITE AND SUBSURFACE CONDITIONS
4.1 GENERAL SITE CONDITIONS
Pavement reconstruction with the same pavement width is to occur along five residential
streets in Fort Worth, Texas as detailed below.
• Beddell —1330 LF
• Bewick - 760 LF
• Flint — 360 LF
• Wayside — 650 LF
• Willing —1940 LF
Pavement design was performed per the current City of Fort Worth Pavement Design
Standards Manual with the exception that only typical testing needed for pavement design
was performed as detailed below. Proctor compaction, UU Triaxial tests and CBR tests
MAS-TEK ENGINEERING & ASSOCIATES

were not performed. CBR correlations .were based on soil strength, swell and index
properties.
4.2 SUBSURFACE CONDITIONS
Subsurface conditions encountered in the borings, including descriptions of the various
strata and their depths and thickness, are presented on the Logs of Borings. Note that depth
on all borings refers to the depth from the existing grade or ground surface present at the
time of the investigation. Boundaries between the various soil types are approximate.
4.3 SITE GEOLOGY
As shown on the Tarrant County sheet of the Geologic Atlas of Texas, the sites are located
in areas underlain by the undivided Pawpaw Formation, Weno Limestone and Denton Clay.
The Formations typically consist of interbedded layers of ciaystone, sandstone, limestone,
clay and marl. Soils derived from the formations are typically highly plastic clays exhibiting a
high shrink/swell potential with variations in moisture content.
4.4 GROUNDWATER CONDITIONS
The borings were advanced using 'continuous flight auger methods. Advancement of the
borings ' using these methods allows observation of the initial zones of seepage.
Groundwater was generally not encountered during drilling and the borings were generally
dry at completion. Groundwater was encountered at Borings B-13, B-14 and B-15 at a depth
of 6' to 9' below existing grade. The borings were backfilled and the pavement patched with
concrete immediately upon completion of the borings each day; therefore, long term water
level readings could not be obtained.
It is not possible to accurately predict the magnitude of subsurface water fluctuations that
might occur based upon short-term observations. The subsurface water conditions are
subject to change with variations in climatic conditions and are functions of subsurface soil
conditions, rainfall and water levels within nearby creeks and the Trinity River.
4.5 SOIL MOVEMENTS
Our scope of work did not include PVR studies or recommendations to reduce soil swell
PVR. However, the subsurface exploration revealed clay soils having a moderate to high
shrink/swell potential depending upon the moisture condition. See Figure 21. Also, as
MAS-TEK ENGINEERING & ASSOCIATES
E09-1205
PAGE 3
mentioned above, soils derived from the geologic formations are typically highly plastic clays
exhibiting a high shrink/swell potential with variations in moisture content. Therefore,
differential soil swell movements should be anticipated at this site. Ponding conditions near
the reconstructed pavements must be avoided. See Section 6.0 regarding settlement
considerations related to existing trees along the curb lines.
5.0 ANALYSIS AND RECOMMENDATIONS
5.1 PAVEMENT RECOMMENDATIONS
We understand that all roads for this project are classified as Residential -Urban Roads (High
Volume) with the City of Fort Worth. The following traffic data was obtained from Table 4.1
of the City of Fort Worth's 2005 Pavement Design Standards Manual and was used in
developing the pavement section recommendations.
Residential
Annual ESALS 35,000
% Growth' 0.0%
Design Life 25 years
5.2 EXISTING FILL SOILS
In order to provide adequate pavement support, we recommend that all existing trench
backfill be tested for compaction. All non -compact backfill (having a compaction level below
95% ASTM D 698) should be removed and replaced In 8 inch compacted lifts. We
recommend that the base of cut be compacted prior to fill placement. We recommend that a
Mas-Tek Engineer or his representative observe the base of cut and compaction operations.
The contract documents should specified that the contractor is responsible to protect all
existing underground utilities from damage during excavation and compaction operations.
After excavation to the required subgrade elevation, the entire subgrade should be
proofrolled. Proofrolling can generally be accomplished using a heavy. (25 ton or greater
total weight) pneumatic tired roller making several passes over the areas. Where soft, loose
or compressible zones are encountered, these areas should be removed to a firm subgrade.
Wet or very moist surficial materials may need to be undercut and either dried or replaced
with proper compaction or replaced with a material which can be properly compacted. Any
resulting void areas should be backfllled to finished subgrade in 8 inch compacted lifts
compacted to 95 percent of maximum dry density as determined by ASTM D 698. Clay soils
having a PI over 25 should be compacted at optimum to +3% above optimum. Sandy soils
having a PI Tess than 25 should be compacted at -2 to +2 percentage points of its optimum
moisture content.
• MAS-TEK ENGINEERING & ASSOCIATES
E09-1205
PAGE 4
After proofrolling is performed and any soft, loose or compressible zones are removed and
replaced, compact upper 8 inches of subgrade to 95% ASTM D698 as specified above.
Then fill to pavement subgrade using on -site clay soils. Compact the fill In 8 inch compacted
lifts compacted to 95 percent of maximum dry density as determined by ASTM D 698 as
specified above. Since lime -stabilization is to be performed, the upper 8 inches of the
pavement subgrade should consist of clay and sandy clay soils that are relatively free of
large rock. Sand should not be used as fill in the upper 8 inches of the pavement subgrade
since lime stabilization is to be performed.
5.3 SUBGRADE PREPARATION
It is recommended that provisions be made in the contract documents to provide for
proofrolling in areas where the subgrade will support new pavements. It is also
recommended that an item be included for removal and replacement of soft materials which
are identified by this procedure. See Section 5.7.
Surficial clays are present at these sites that are subject to losses in shear strength with
increases in moisture content beneath the paving. They typically react with hydrated lime
which serves to improve their support value at higher moisture levels and provides a firm,
uniform subgrade beneath the paving.
Note 1: Areas containing high levels of sulfates are noted below. These areas should not be
lime stabilized. The pavement should be thickened and constructed over a compacted
unlimed subgrade per this report.
Note 2: If pavement grades remain unchanged, most pavement areas will be underlain by
2" to 5" of crushed stone base materials. In some areas, up to 8 inches of crushed stone will
be present below the pavement subgrade (assuming pavement grades remain unchanged).
Note: In the area of B16, B17 and B18, an asphalt layer is present over concrete pavement
to depths of 8 to 9 inches below existing grades. After pavement removal, these areas will
require 1 to 2 inches of fill prior to liming to achieve pavement subgrade (if pavement grades
remain unchanged).
MAS-TEK ENGINEERING & ASSOCIATES
E09-1205
PAGE 5
After final grading for the new pavement, it should be verified with test pits that the thickness
of the crushed stone is no greater than 5 inches prior to liming. If the crushed stone
thickness is less than 5 inches, lime stabilization can be performedto a depth of 8 inches as
specified in this report. If the crushed stone thickness is over 5 inches, some of the crushed
stone should be replaced with on -site clay soils to limit the maximum crushed stone
thickness to less than 5 inches. Then lime stabilization can be performed to a depth of 8
inches.
5.4 LIME STABILIZATION
Based upon the results of Atterberg limits testing, nine (9) percent hydrated lime by dry
weight (54 pounds per square yard per 8-inch depth) should be anticipated to stabilize the
existing clay subgrade. Based on sulfates tests performed on subgrade soils at random
boring locations, sulfates levels are generally below 1000 ppm in most areas. Therefore,
conventional lime stabilization procedures may be used in most areas per TxDOT Item 260.
See exception noted below. It should be determined after final grading that sulfates Levels
are below 2000 ppm in all areas to be limed.
Note: In one area (Willing Avenue between Pafford Street and Dickson Street), lime
stabilization is not recommended due to the presence of high sulfates levels over 2000 ppm
within the high plasticity clay beneath this street. In this area, the clay subgrade should be
compacted at optimum to +3% above optimum to 97% ASTM D698 after fine grading (prior
to concrete placement). The subgrade should be kept moist until paving. Then just prior to
paving, the subgrade should be watered just prior to paving to allow concrete placement
over a moist damp subgrade. Sand should not be allowed for fine grading. If a rain event
occurs prior to paving, the subgrade must be aerated and re -tested for compaction prior to
paving.:
The actual lime requirement will depend upon the actual subgrade soils exposed at final
grade. We recommend that lime / Atterberg limits tests and sulfate tests be performed once
final pavement subgrade has been achieved in order to determine the optimum amount of
hydrated lime required to stabilize the subgrade and to verify that sulfates levels are below
2000 ppm.
MAS-TEK ENGINEERING & ASSOCIATES
E09-1205

,t
,t
The lime should be thoroughly mixed and blended with the highly active subgrade soil
(TxDOT Item 260) and the mixture compacted to a minimum of 98 percent of maximum dry
density as determined in accordance with ASTM D698, within 2 percentage points of the
soil's optimum moisture content. We recommend that this lime stabilization extend 1 to 2
feet beyond pavement edges, if possible, in order to reduce the effects of shrinkage during
extended dry periods. After blue top stakes are set in preparation for grading the lime
stabilized subgrade, depth checks should be performed to verify that the specified depth of
stabilization is present after final grading of the stabilized subgrade.
Sand should be specifically prohibited beneath pavement areas during final grading (after
stabilization), since these more porous soils can allow water inflow, resulting in heave and
strength loss of subgrade soils. It should be specified that only Time -stabilized soil (or
compacted rock fines where limestone is present at final pavement subgrade) will be
allowed for fine grading. After fine grading each area in preparation for paving, the subgrade
surface should be lightly moistened, as needed, and recompacted to obtain a tight non -
yielding subgrade.
Project specifications should allow a curing period between initial and final mixing of the
lime/soil mixture. After initial mixing, the lime treated subgrade should be lightly rolled and
maintained at or within 5 percentage points above the soil's optimum moisture content until
final mixing and compaction. We recommend a 2 to 3 day curing period for these soils. The
following gradation requirements are recommended for the stabilized materials prior to final
compaction:
Percent
Minimum Passing 1 3/4" Sieve 100
Minimum Passing 3/4" 85
Minimum Passing No. 4 Sieve 60
All non -slaking aggregates retained on the No. 4 sieve should be removed prior to testing.
5.5 DESIGN AND CONSTRUCTION REQUIREMENTS
The stabilized subgrade should be protected and moist cured or sealed with a bituminous
material for a minimum of 7 days or until the pavement materials are placed. Pavement
areas should be graded at all times to prevent ponding and infiltration of excessive moisture
on or adjacent to the pavement areas.
MAS-TEK ENGINEERING & ASSOCIATES
E09-1205
PAGE 7
Due to the presence of expansive clay soils, differential pavement movements should be
anticipated. Inspection during construction is particularly important to insure proper
construction procedures are followed. All joints must be effectively seated. Ponding
conditions should not be allowed in any area.
Where asphaltic concrete pavement is used, a geotextile separator should be placed on the
lime -stabilized subgrade at the contact between the flex base and the lime -stabilized
subgrade. The geotextile shall be as specified in the "Special Technical Specifications" in
Appendix C of the City of Fort Worth's 2005 Pavement Design Standards Manual.

Note 1: The concrete thickness should be increased by 1.5 inches along Willing Avenue
(between Pafford Street and Dickson Street), where lime stabilization is not recommended
due to high levels of soluble sulfates. Sulfate resistant concrete should be used. Type II
cement in combination with 25% Class F flyash is locally available and is commonly used in
the DFW Metroplex for this application. An asphaltic membrane should be placed above the
compacted soil subgrade to minimize sulfate reaction after concrete placement. The
membrane should consist of an asphalt sealant such as an MC-20 or approved equal and
placed at a rate of 0.25 gallons per square yard.
Note 2: Asphalt pavement is not recommended along Willing Avenue (between Pafford
Street and Dickson Street) where highly expansive clays containing high level of soluble
sulfates are present and lime stabilization will not be performed.
5.6.2 DESIGN REQUIREMENTS
The concrete having a minimum 28 day compressive strength of 3,600 psi. Concrete quality
will be important in order to produce the desired flexural strength and long term durability.
Assuming a nominal maximum aggregate size of 1 inch to 1 3/8 inches, we recommend that
the concrete have entrained air of 5 percent (± 1%) with a maximum water cement ratio of
0.40.
Proper joint placement and design is critical to pavement performance. Load transfer at all
joints and maintenance of watertight joints should be provided. Control joints should be
sawed as soon as possible after placing concrete and before shrinkage cracks occur. All
joints including sawed joints should be properly cleaned and sealed as soon as possible to
MAS-TEK ENGINEERING & ASSOCIATES
E09-1205
PAGE 9
avoid infiltration of water.
The Joint construction and spacing and reinforcing should be in accordance with the City of
Fort Worth's 2005 Pavement Design Standards Manual based on the actual concrete
thickness used for each road. We recommend that the perimeter of the pavements have a
stiffening curb section to prevent possible distress due to heavy wheel loads near the edge
of the pavements and to provide channelized drainage.
All asphaltic concrete construction should comply with requirements of TxDOT, Item 340
(1993 Edition). The flex base should meet requirements of TxDOT Item 247, Type A, Grade
1, compacted in 4 to 6 inch lifts at or above optimum moisture content to'a minimum of 95%
Modified Proctor density (ASTM D1557).
5.7 PAVEMENT CONSIDERATIONS
It Is recommended that provisions be made in the contract to provide for proofrolling in areas
where the subgrade will support new pavements. If is also recommended that an item be
included for removal and replacement of soft materials, which are identified by this
procedure.
Proofrollingcan generally be accomplished using a heavy (25 ton or greater total weight)
pneumatic tired roller making several passes over the areas. Where soft or compressible
zones are encountered, these areas should be removed to a firm subgrade. Wet or very
moist surficial materials may need to be undercut and either dried or replaced with proper
compaction or replaced with a material which can be properly compacted. Any resulting void
areas should be backfilled • to finished subgrade in 6 inch compacted lifts compacted to 95
percent of maximum dry density as determined by ASTM D698. Clay soils having a PI over
25 should be compacted at optimum to +3% above optimum. Sandy soils having a PI less
than 25 should be compacted at -2 to +2.percentage points of its optimummoisture content.
Achieving the required field density is dependent upon the adequate pulverization of the clay
fill materials, the magnitude of compaction energy and the maintenance of field moisture
near optimum. All joints and pavements should be inspected at regular intervals to ensure
proper performance and to prevent crack propagation.
The soilsat the site are active and differential heave within the paving areas will occur. In
some areas, relatively deep expansive clay soils are present. Large upward pavement
movements due to soil swelling are anticipated in these areas. Large differential upward

1i
pavement movement could also occur in any areas where the pavement is widened. If it is
desired to reduce differential upward soils swell movements, excavation and moisture
conditioning in lifts would be required. The extent of excavation would depend upon the
desired tolerance for movement.
The service life of paving may be reduced due to water infiltration into subgrade soils
through heave induced cracks in the paving section. This will result in softening and Toss of
strength of the subgrade soils. A regular maintenance program to seal paving cracks will
help prolong the service life of the paving. The life of the pavement can be increased with
proper drainage. Areas should be graded to prevent ponding adjacent to curbs or pavement
edges. Backfill materials, which could hold water behind the curb, should not be permitted.
Flat pavement grades should be avoided.
Due to the presence of deep utility backfiil in some areas and highly expansive clay in other
areas, the use of reinforced concrete pavement would be preferred to accommodate
differential pavement movements.
5.8 SITE GRADING AND DRAINAGE
All grading should provide positive drainage away from the proposed pavements and should
prevent water from collecting or discharging near the pavements. Water must not be
permitted to pond adjacent to the runway pavements during or after construction. Otherwise,
soil swell movements could exceed the estimates contained in this report.
The pavements will be subject to some post construction movement. Joints in the
pavements should be sealed to prevent the infiltration of water. Since some post
• construction movement of pavement may occur, joints should be periodically inspected and
resealed where necessary.
5.9 FIELD SUPERVISION AND DENSITY TESTING
Field density and moisture content determinations should be made on each lift of fill with a
minimum of 1 test per 150 I.f. of pavement and/or utility backfill. Supervision by the field
technician and the project engineer is required. Some adjustments in the test frequencies
may be required based upon the general fill types and soil conditions at the time of fill
placement.
MAS-TEK ENGINEERING & ASSOCIATES
E09-1205
PAGE '11
Many problems can be avoided or solved in the field if proper inspection and testing
services are provided. It is recommended that all site and subgrade preparation and
pavement placement be monitored by a qualified engineering technician. Density tests
should be performed to verify compaction and moisture content of any earthwork. Inspection
should be performed prior to and during concrete and asphalt placement operations. Mas-
Tek Engineering & Associates, Inc. employs a group of experienced, well -trained
technicians for inspection and construction materials testing who would be pleased to assist
you on this project.
6.0 EXISTING TREES ALONG CURB LINES
Numerous mature trees are present near the curb lines of the existing streets in most of the
areas investigated. The roots of mature trees absorb large amounts of moisture from the
supporting soils to depths of over 15 feet. The lateral limits of tree root influence extend at
least 5' beyond the unpruned drip line (and to greater distances when the ground beneath
the drip lines is paved). Tree root systems often cause soil shrinkage and localized
pavement settlement.
To reduce future settlement after reconstruction, root barriers could be considered. An
arborist should be contacted regarding the required depth of the root barrier and whether or
not this is a viable solution. Root barriers along both curb lines would require large roots to
be severed. This might kill the trees. If this occurred, large pavement heave would then
occur as described above (same as removing trees). If the barriers are effective in reducing
soil suction from the root systems, large differential heave would still occur as the soils
regain lost moisture causing differential heave due to soil swelling. Due to these concerns,
root barriers are probably not a viable solution at this time. Root barriers would have been
an alternative during original construction if they had been installed when the trees were
originally planted.
In our opinion, the most practical solution is to reconstruct the roadways with reinforced
concrete. An additional 1 to 2 inches of concrete (over the required design thickness) could
be used in areas containing existing trees with drip lines extending within 10 feet of the curb
lines. The thickened pavement would provide additional rigidity to the pavement to assist in
accommodating differential deflections caused by post construction shrink/swell movements
caused by trees. Additional steel reinforcement could be used to further stiffen the
pavement. Either larger bars on a closer spacing, or two mats of steel could be used. A

structural engineer should be consulted regarding the most cost effective reinforcement
design for roadways bordered with mature trees.
It should be anticipated that differential shrink/swell movements will occur beneath the new
roads. If differential settlements due to continued shrinkage caused by the trees become
objectionable, these areas could be mudjacked in the future as needed to level the
pavement.
7.0 - LIMITATIONS
The professional services, which have been performed, the findings obtained, and the
recommendations prepared were accomplished in accordance with currently accepted
geotechnical engineering: principles and practices. The possibility always exists that the
subsurface conditions at the site may vary somewhat from those encountered in the test
borings. The number and spacing of test borings were chosen in such a manner as to
decrease the possibility of undiscovered abnormalities, while considering the nature of
loading, size; and cost of the project. If there are any unusual conditions differing
significantly from those described herein, Mas-Tek Engineering & Associates, Inc. should be
notified to review the effects on the performance of the recommended foundation system.
The recommendations given in this report were prepared exclusively for the use of the
client, and their consultants. The information supplied herein is applicable only for the
design of the previously described development to be constructed at locations indicated at
this site and should not be used for any other structures, locations, or for any other purpose.
We will retain the samples acquired for this project for a period of 30 days subsequent to the
submittal date printed on the report. After this period, the samples will be discarded unless
otherwise notified by the owner in writing.

Identify all subcontractors/suppliers you will use on this project
Failure to complete this form, in its entirety with requested documentation, and received by the Managing
Department on or before 5:00 p.m. five (5) City business days after bid opening, exclusive of bid opening date, will
result in the bid being considered non -responsive to bid specifications.
The undersigned Offeror agrees to enter into a formal agreement with the M/WBE firm(s) listed in this utilization
schedule, conditioned upon execution of a contract with the City of Fort Worth. The intentional and/or knowing
misrepresentation of facts is grounds for consideration of disqualification and will result in the bid being considered
non -responsive to bid specifications
M/WBEs listed toward meeting the project goal must be located in the nine (9) county marketplace or
currently doing business in the marketplace at the time of bid. Marketplace is the geographic area of Tarrant,
Parker, Johnson, Collin, Dallas, Denton, Ellis, Kaufman and Rockwall counties.
Identify each Tier level. Tier is the level of subcontracting below the prime contractor, i.e., a direct payment from
the prime contractor to a subcontractor is considered 1st tier, a payment by a subcontractor to its supplier is
considered 2nd tier
ALL M/WBEs MUST BE CERTIFIED BEFORE CONTRACT AWARD.
Certification means those firms, located or doing business at the time of bid opening within the Marketplace, that have been
determined to be bonafide minority or women businesses by the North Central Texas Regional Certification Agency
(NCTRCA), or the Texas Department of Transportation (TX DOT), highway division. Disadvantaged Business Enterprise
(DBE) is synonymous with Minority/Women Business Enterprise (M/WBE).
If hauling services are utilized, the prime will be given credit as long as the M/WBE listed owns and
operates at least one fully licensed and operational truck to be used on the contract. The M/WBE may lease
trucks from another M/WBE firm, including M/WBE owner -operators, and receive full M/WBE credit. The
M/WBE may lease trucks from non-M/WBEs, including owner -operators, but will only receive credit for the
fees and commissions earned by the M/WBE as outlined in the lease agreement.
