Assuming that the average garbage truck represents 2.3 ESALS, we are designing our neighborhood
streets so that they can handle approximately 200 garbage trucks a week. Based on experience from
CONTRACT 35, the ESALS break point between a 6-inch and 7-inch concrete pavement section with a
Drainage Coefficient of 0.7 is approximately 240,000 ESALS over the 25-year design life of the
pavement or 9,600 ESALS per year which represents approximately 80 garbage trucks a week. For
comparison purposes, it takes approximately 10 delivery trucks or 750 passenger cars to equal the
ESAL load of one garbage truck.
We propose that to perform one (1) 8-hour traffic count on Merritt Street (to serve as similar data on
Priddy Lane) and one (1) 8-hour traffic count on Westwind Drive to determine an appropriate traffic
volume and weight information utilized in determining ESALS for the design. Once the traffic count
with vehicle information data is collected, we can provide our recommendations for ESALS over the
design life of the paving. The City can then decide to use the more conservative minimum values from
the City's Pavement Design Standard Manua12005 Edition, or the recommendation we provide. The
proposed cost to perform the traffic data collection data and provide the ESAL recommendation is as
follows:
$1, 800.00 Traffic Count Data Collection (Two (2) 8-hour counts)
$ 250.00 ESAL Recommendation
$2,050.00 Total Proposed Amount for Traffic Data Collection
As outlined in this proposal, we are proposing to provide these additional services for a total fee of
$15,208 ($13,158 for geotechnical investigations and pavement design and $2,050 for traffic count data
to determine ESAL). We are available to meet with you at your convenience to discuss this matter
further if you desire.
Sincerely,

108 West 8th Street, Suite 200
Fort Worth, Texas 76102
Attn: Mr. Carl J. Krogness, P.E.
Dear Mr. Krogness:
PROPOSAL FOR:
GEOTECHNICAL ENGINEERING INVESTIGATION
AND PAVEMENT DESIGN
CONTRACT 50
FORT WORTH, TEXAS
INTRODUCTION
CMJ Engineering, Inc. (CMJ) is pleased to submit a proposal for providing geotechnical
engineering services in conjunction with the above-referenced project. We prepared this
proposal based on the preliminary scope submitted to this office by Mr. Carl Krogness. This
geotechnical investigation will be performed in accordance with the City of Fort Worth's 2005
Pavement Design Standards Manual.
The project, as currently planned, wi(I consist of refurbishing specified portions of three streets
in Fort Worth including: Merritt Street (White Settlement Rd. to Blackstone St.), Priddy Lane
(White Settlement Rd. to Melbourne St.) and Westwind Drive (Skylake Dr. to Lake Country Dr.).
Specific refurbishment lengths range from approximately 1,20Q to 1,500 linear feet with an
approximate combined total project length of 4,100 linear feet.
For purposes of this proposal, it is assumed that all borings are accessible to truck-mounted
drilling equipment. ln addition, it is assumed that underground utilities at boring locations will be
coordinafed by CMJ.

SCOPE OF SERVICES
I. BASIC SERVICES
A. SUBSURFACE EXPLORATION
Experienced drillers and technicians will evaluate subsurface conditions with a total of eleven
(11) continuously sampled borings distributed as follows:
Merritt Street — Four (4) borings to 10 feet
Priddy Lane — Three (3) borings to 10 feet
Westwind Drive — Four (4) borings to 10 feet
The field personnel will drill the borings using truck-mounted equipment. Cohesive and non-
cohesive soil samples will be continuously obtained using 3-inch diameter Shelby tube sampler$
and 2-inch diameter standard split-spoon samplers, respectively. In additian, rock encountered
will be evaluated by use of Texas Department of Transportation (TXDOT) cone penetration
tests. A soils logger will extrude the samples in the field, check the samples for consistency
with a hand penetrometer, carefully wrap them to preserve their condition, and return them to
the laboratory for testing. A log of each boring will be prepared to document field activities and
results.
CMJ's personnel will stake the boring locations using normal taping procedures. Approximate
locations of the borings will be shown on the plan of borings. Precise surveying of boring
locations and elevations is not included in the cost estimate. These services may be provided
as Additional Services upon request. At the completion of drilling operations, boreholes will be
backfilled with cement grout and the upper two feet plugged with bentonite pellets.
B. LABORATORY SERVICES
Considering the planned improvements, anticipated soil conditions and geology, laboratory tests
will be required for classification purposes, and to determine strength characteristics. The
following types of tests are therefore recommended:
� moisture content and soil identification
• liquid and plastic limit determinations
• percent passing No. 200 sieve
• unconfined compression tests on soil
• unit weight determinations
• absorption pressure and/or one-point pressure swell tests
• lime series test
. soluble sulfate tests

• unconsolidated undrained triaxial compression tests
The specific types and quantities of tests will be determined based on geologic conditions
encountered in the borings.
C. ENGINEERING SERVICES
An engineering report will be prepared to present the results of the field and laboratory data
together with our analyses of the results and recommendations. We will provide three copies of
the report. The report will address:
• general soil and ground-water conditions
• earthwork recommendations
• guidelines for pavement subgrade stabilization
• pavement thickness design
Items other than those specified above, which are revealed by these studies or are necessitated
by a change in project scope, may require revised field, laboratory, and engineering services.
These services, if required and requested, will be performed as Additional Services. Additional
Services are described in Section II.
D. COMPENSATION FOR BASIC SERVICES
It is proposed that the Basic Services described above be performed on a unit price basis, in
accordance with the attached Basic Services Cost Estimates. Based on the anticipated scope
and the attached Basic Services Cost Estimates, the total cost of Contract 50 is $11,962.
This cost for Basic Services will not be exceeded without prior authorization.
The estimated costs shown in this proposal are based on the anticipated soil conditions. The
final invoice will be based on the specific quantities drilled and tested. If unanticipated
conditions are encountered during drilling, we will notify you accordingly.
E. SCHEDULE FOR BASIC SERVICES
Weather permitting, we plan to initiate these studies within seven days of receipt of notice to
proceed, and anticipate that two working days will be required to complete the subsurface
exploration for the sites (weather conditions permitting). You will receive the final report
approximately three to four weeks following the completion of the field phase. We will make
preliminary design data available sooner if necessary.
