d. Identify and resolve utility conflicts: The Engineer will provide affected Utilities <br /> with preliminary plans for review with the intent to show conflicts with existing <br /> facilities. The Engineer will, if necessary, arrange for one meeting with the <br /> affected utilities in order to determine design changes, or potential relocation of <br /> facilities by the Utility. The Engineer will meet with the County and discuss <br /> potential solutions to identified utility conflicts. <br /> e. Incorporate design changes/relocations: The Engineer, using information <br /> gathered in previous steps will incorporate the design changes or utility <br /> relocations as needed to accommodate the project. At the time of preparing this <br /> proposal we have identified that a 30" waterline will need to be relocated at 69th <br /> street. We have also identified the drainage culvert at this location will need to <br /> be extended to accommodate the proposed intersection improvements. Utility <br /> relocation design is limited to these two items in this proposal. <br /> 5. Geotechnical engineer will core and bore sample existing flexible pavement <br /> section materials and underlying soils in order to identify and report existing <br /> conditions throughout the subject area. Provide 20' deep bores at 8 locations <br /> (one for each signal foundation) and provide structural design parameters for <br /> foundation design. Samples of flexible pavement section materials obtained will <br /> be utilized in laboratory testing for development of a Full Depth Reclamation mix <br /> design blend(s). Consideration will be given to admixture quantity, costs, desired <br /> structural coefficient and constructability. Final design blend(s) recommendations <br /> will be provided <br /> 6. Engineer will prepare Master Plan layout and preliminary design at 1" = 40' scale <br /> on 36" x 96" sheets that includes horizontal alignment of proposed <br /> improvements, and typical sections at key locations. Final product will be in <br /> AutoCAD format. <br /> At the intersections of 58'Avenue with69th Street, the Engineer will include <br /> conceptual intersection layouts with proposed modifications to horizontal <br /> geometry to accommodate additional vehicular use lanes, cross-walks, signal <br /> structure locations, proposed head alignments, cabinet locations, and power <br /> sources. <br /> Limits of work: <br /> • 58th Avenue from southerly edge 57th Street to southerly edge <br /> CR-510 <br /> 7. Engineer will identify issues and conflicts that affect proposed road <br /> improvements and drainage. <br /> 8. Engineer will develop opinion of construction cost of proposed improvements and <br /> any alternatives being considered. <br /> BCG INITIAL CLIENT INITIAL <br /> Page 3 of 14 <br />
