INDIAN RIVER COUNTY 66th Avenue Phase 113, 491h to 69th Roadway Widening Project Number: IRC -1505 AMENDMENT NO. 8 TO THE PROFESSIONAL ENGINEERING/LAND SURVEYING SERVICES AGREEMENT BETWEEN KIM LEY -HORN AND ASSOCIATES, INC. AND INDIAN RIVER COUNTY, FLORIDA. This is an amendment to the existing Engineering/Land Surveying Services Agreement (AGREEMENT) dated February 22nd, 2005 between Kimley-Horn and Associates, Inc. (ENGINEER) and Indian River County (COUNTY). This amendment addresses changes in "Section III - Scope of Services", "Section V - Compensation" and "Section XVI -Duration of Agreement" of the AGREEMENT. Amendment Description "SECTION III -SCOPE OF SERVICES" is being modified to incorporate the following: 66th Avenue Phase IB — 66th Avenue and 57th Street — Traffic Signalization The COUNTY desires to improve the intersection by installation of a mast arm traffic signal, pedestrian crosswalks and curb ramps, including sidewalk ramps and landings, associated signage and miscellaneous pavement markings as needed. It is understood that the CONSULTANT will provide the geotechnical investigation findings necessary to support the foundation design calculations and digital geometric roadway design files. A. Geotechnical Investigation: The geotechnical investigation will include four (4) Standard Penetration Test (SPT) borings to a depth of 35 feet using a procedure similar to the Standard Penetration Test outlined in ASTM D-1586. The SPT borings will be drilled at the four corners of the intersection in accessible locations as close as possible to the proposed mast arm foundations. The SPT borings will be sampled at 18 -inch or 24 -inch intervals to 10 feet deep and at 5 -foot intervals below 10 feet. Each sample will be removed from the sampler in the field and then examined and visually classified by our crew chief. Representative portions will be sealed and packaged for transportation to our laboratory for further analysis as required. Water level observations will be made in the boreholes during the drilling operation. For the purposes of this proposal, we have assumed that maintenance -of -traffic (MOT) will not be required to perform the soil borings. LABORATORY TESTING Routine laboratory visual classification will be performed along with specific classification tests deemed necessary (i.e., sieve analysis, Atterberg limits and organic contents). All laboratory tests will be performed in general accordance with applicable ASTM standards. ENGINEERING ANALYSIS AND REPORT Engineering analysis of all data obtained will be made to evaluate general subsurface conditions, and to provide the soil parameters listed above for structural verification of the standard FDOT mast arm pole design.
