We understand that portions of three existing residential roadways in the City of Fort Worth are being planned for reconstruction. The roadway sections are as follows: e Colvin Street — 1800 litiear feet from N�w York Avenue to Beverly Avenue e Irma Street — 780 linear feet from Evans Avenue to New York Avenue b Roberts Street — 515 linear feet from IH35 W South Freeway to Evans Street The purpose of the proposed study will be to provide geatechnical engineering recommendatians for use in the design of the roadways. The scope of service indudes exploring subsurface soil conditions, obtaining physical soil properties l�y laboratory testing, and providing geoteciinical reconimendations for use in determining subgrade treatment and pavement thickness complying with the City of Fort Warth Transportation and Public UVorks Department Pavement Design Standards Manual 2005, SCOPE t�F BASIC SERVtCES Field Exploration � Contact the Texas One Call system to locate buried utilities within existing easements and right-of-ways, and coardinate with City of Fort Worth for utility locatians.

The tests wili be used fa evaluate and classify the soils, identify subsurface site characteristics, and provide data for analysis. These tests include o Atterberg limits (liquid and plastic limits, 8 tests maximum) s Percent passing No. 200 sieve (8 tests maximum) • Moisture content (24 tests maximum) s Sweil at overburden (3 tests maxin�um) • Soluble sulfates by Golorimeter (3 tests maximum) @ Optimum lime content (Eades & Grim) (3 tests maximum) Q Unconsolidated-Undrained (UU) triaxial tests (8 tests maximum) Kleinfelder will retain soil �nd rock samples for 30 days after complefion of laboratory testing. Further storage or transfer of samples can be made at the owner's expense upon written request.

Ct�MPEhlS�4TiOtV Kleinfelder proposes to perform the Basic Services for a lurr�p-sun� fee of $9,�OQ. This amount will not be �xceeded without prior approvai. Freese and Nichols and Kleinfelder may subsequently agree ii7 writing to provide for additional services to be render�d under this agreem�nt for additional, negotiated compensation. Services provided by Kleinfelder will be consistent with the engineering standards prevailing at the time and in the area that the work is performed; na other tn�arranty, express or implied, is intended. ANTICIPATED SCHEQULE The field coordination will begin 2 to 3 days from the time authorization. Typically, obtaining a streets use permit, marking the boring locations and meeting with the City of Forf tNorth Public Works Department for utility clearance requires 2 to 3 days. The fieldwork will begin ance the boring lacations have been cleared by both Texas One Gall system and fhe Gity of Fort Worth and a streets use permit is received from the City. The fieldwork will require approximately 1 day, depending on wcather conditions. The laboratory testing should be completed within 2 weeks after completion of the field exploration. The analyses and report preparation should be completed within 2 w�eks after compietion of the laboratory testing. LEMtTATIONS Our work will be perFormed and findings obtained in substantial conformance with the geofechnical engineering practice that exists within the area at the time of our investigation. No warranty, either express or implied, is r�nade. We appreciate the opportunity to continue our work on this project and look forward to working with you.
