This Letter Agreement was requested by Mr. Abe Calderon, P.E. The scope of services included in this Letter Agreement is based upon a site visit with City representatives Abe Calderon, P. E., and Ryan Jeri, P. E., and upon additional information provided by the City. It is our understanding that the requested scope of services will consist basically of evaluation of the pavement subgrade in areas of distressed pavement, and to provide a professional opinion of the cause of the pavement distress. The distressed areas are located in the vicinity of 4628 Foard Street and on Nolan Street just south of Childress. These locations are shown on Fort Worth MAPSCO 92 B and 92 C(2002 edition). Scope of Services I. Basic Services — Evaluation of Distressed Pavements A. Subsurface Exploration Based upon a cursory review of geologic maps, and previous experience in the vicinity, the project site is within the Grayson Marl and Main Street Limestone geologic formations, and is also close to the contact of the Woodbine geologic formation. SubsurFace conditions will be evaluated with 4 exploratory borings in selected distressed pavement and subgrade areas. We anticipate that 3 of the borings will be perFormed on Foard Street and one boring on Nolan Street. The borings will be drilled to a depth of 10 feet below existing pavement surface or to the to,p —",i �?-�� i.�I�I ;; —= � � �, r f: � ^o t�, '�' �' }, �' � � � '°;'�V � �,�U �v, � ,� 1 l � f �7 1�1 �, ,�]�'�i '�'��;�� I��1'`?� � � :� �j� :r n �`:� nl ��Z � '!

July 5, 2004 Page 2 of rock (if any), whichever is less. The borings will be continuously sampled to better define the detailed subsurface conditions. The borings will be advanced using a truck-mounted drill rig. Cohesive and non-cohesive soil samples will be obtained using nominal 3-inch diameter thin-walled tube samplers and 2-inch diameter standard split-barrel samplers, respectively. The samples will be extruded in the field, checked for consistency with a hand penetrometer, wrapped to limit loss of moisture, and transported to the laboratory for testing of selected specimens. A geotechnical technician will prepare a field log of each boring to visually document subsurface materials encountered. Rock encountered (if any) will be field tested by use of Texas Department of Transportation (TX DOT) cone penetration tests. Water levels (if any) in open boreholes will be observed and recorded during the drilling operations. Upon completion of drilling, the boreholes will be backfilled the full open depth with rodded sand to the bottom of the pavement structure. The actual pavement thickness (concrete or asphalt) will be filled with bag concrete mix (Sackrete). Traffic cones will be placed on each end of the drill rig to temporarily block off one lane of the street for a short distance during drilling of each boring. No other traffic control is included in the Basic Services Budget. Any other required traffic control, including barricades, flagmen, flashing lights, signs, etc. will be provided by the City, or provided by GREGEO as Additional Services. GREGEO will stake or mark the boring locations using normal taping procedures from existing topographic features and survey points provided by the City. Precise surveying of boring locations and elevations is not included in the Basic Services Budget. It is our understanding that the City will provide any available general survey data to GREGEO. B. Laboratory Services Laboratory tests will be performed for classification purposes, and to determine pertinent engineering properties of the subsurface materials. The following types of tests are anticipated: • moisture content and Pocket vane shear • percent passing no. 200 sieve • liquid and plastic limit tests • UU Triaxial tests on soil • unit weight determinations • free swell tests • sulfate content tests • The specific types and quantities of tests will be determined based on subsurface conditions encountered in the borings. C. Professional Services A geotechnical engineering report will be prepared to present the results of the field and laboratory data together with analyses, conclusions, and recommendations. Three copies of the report will be provided. The report will include: • General soil and ground-water conditions encountered in the borings �--_ =-- ;._ �, ;;, �� ;D' ��. f' :.��i�i' :�` �°.��'�JJ��U �;y �f ��'J e� J�-.'� '�, , � �� a r G> > r�l�f �°1L�`�� ti '�'J�,b� -�'��:U�� , it �G n i � �':':'�' '�!n. ��' �� ✓'1 i Evaluation of Distressed Pavements — Foard and Nolan Streets Mr. Abraham W.

These recommendations will be general and will not be specific design recommendations. One meeting at City offices to discuss and present the results of the study to City staff has been included in Basic Services. No other meetings are included in Basic Services. Items other than those described above, which are later determined to be required due to unexpected subsurface conditions, or otherwise, or are necessitated by a change in project scope, may require additional field, laboratory, and professional services. These services, if authorized, will be performed as Additional Services. Additional Services are described in Section II. Payment for Basic Services The Basic Services described above will be perFormed on a unit price basis, in general accordance with the attached Basic Services Budget. For budget purposes, a maximum cost of $8,200 is recommended. The costs for the various items may vary, however the total cost for Basic Services will not be exceeded without prior authorization. Basic Services Schedule Basic services will be initiated within 2 days of receipt of notice to proceed. It is anticipated that 5 working days will be required to stake the boring locations and coordinate with utility companies and City personnel to locate and mark underground utilities in the vicinity of the proposed borings. We anticipate that 1 to 2 working days will be required to complete the subsurface exploration. The schedule for field activities is based upon suitable weather conditions. The laboratory-testing program is anticipated to take approximately 10 working days. The report will be issued approximately 10 working days following the completion of laboratory testing. Preliminary geotechnical data will be provided sooner, if necessary and if available, to facilitate review by City staff. II. Additional Services A. Authorization and Scope Additional Services will be perFormed only if specifically requested and authorized by the City. Additional Services may consist of the following: • Additional subsurFace exploration, including quantities or items other than described in Basic Services. • Bulldozer or other equipment services required to achieve access to boring locations (not anticipated to be required). • Stand-by time or time in excess of 15 minutes required for travel between boring locations due to circumstances beyond our control. • Traffic control, other than specifically described under Basic Services. • Repair of surface areas, other than borehole plugging described in Basic S�i�e�.--=_-= �r N-� �,A 2`� I''1 ID �''ff'�' ' ' J 'i� "„�!�:� 1��l�iVJ��LI �� `'�?� !`�� :,:;,, J,�;�n �LGS. , ,., � Evaluation of Distressed Pavements — Foard and Nolan Streets Mr. Abraham W.
