IMPROVEMENT OF THE INTERSECTION OF SR 60&43RD AVENUE <br /> PROFESSIONAL CIVIL ENGINEERING& STRUCTURAL ENGINEERING <br /> SERVICES <br /> AMENDMENT NO. 7 TO THE PROFESSIONAL ENGINEERING/LAND SURVEYING <br /> SERVICES AGREEMENT BETWEEN ARCADIS US, Inc. (fka ARCADIS G&M, Inc.), <br /> Inc.AND INDIAN RIVER COUNTY, FLORIDA. <br /> This is an amendment to the existing Engineering Services Agreement (AGREEMENT) dated <br /> September 6, 2005 between ARCADIS US, Inc. (ENGINEER) and Indian River County <br /> (COUNTY). This amendment addresses changes in "Section I—Project Limits and Description", <br /> "Section III- Scope of Services", and "Section V- Compensation". <br /> Amendment Description <br /> This Amendment includes the following: <br /> "SECTION I-PROJECT LIMITS AND DESCRIPTION"is being modified to incorporate <br /> the following: <br /> Consultant services are required for the preparation of road design plans; bridge plans; permit <br /> applications and utility relocations associated with the construction of SR 60 / 43'1 Avenue <br /> Intersection Improvements. <br /> ARCADIS US, Inc., was contracted to design the widening of 43rd Avenue from 26th Street to <br /> 181 Street. The project was designed at the same time as the widening of 43rd Avenue from 18th <br /> Street south to 8th Street, designed by Carter Associates, Inc. Both designs assumed that <br /> construction would happen concurrently, so design of a transition from the new four lane <br /> configuration to the existing two lane configuration was not necessary for either plan. In addition, <br /> part of the stormwater drainage system for the ARCADIS design was to be directed south and <br /> treated in the Carter design. It has been determined that the roadway widening and drainage <br /> system south of 18t street (the Carter design) will not be constructed at this time and the plans <br /> should be revised to provide for a transition from four lanes to two lanes. In addition, a new <br /> drainage system design to accommodate the portion of the ARCADIS project that was directed <br /> south into the Carter project is necessary. The design will consist of inlets and pipes to convey <br /> runoff from 43rd Avenue to a new stormwater drainage pond. Hydraulic calculation will be <br /> performed to size the pipe system and the stormwater drainage pond. The roadway plans and <br /> profile sheets will be revised to show required improvements. <br /> The FDOT has reviewed the previously submitted plans and has provided comments to the <br /> COUNTY and ENGINEER. ENGINEER will revise the plans to address the FDOT's comments <br /> and to update the plans to the current FDOT design standards. <br /> The following plan sheets will be modified: <br /> Page 1 of 6 <br /> G:\LNR Support\Proposals\WPB\2015\SR 60-43rd Avenue\SR60-43RD AVE AMENDMENT 7 3-24-15.doc <br /> 117 <br />
