EXHIBIT A ATKINS Proposal to Provide Professional Engineering Services for IRC Project No. 1638 — 6th Avenue Resurfacing Project US -1 to 21St Street Vero Beach, Indian River County, Florida Indian River County (County) is proposing to improve the safety and operation of 6t' Avenue from Highway US -1 to 21" Street. Approximately 3,700 LF (0.7 miles) of the road (15th Place north to 21" Street) are within the city limits of Vero Beach, FL. The proposed improvements consist of milling and resurfacing the existing asphalt pavement, filing in sidewalk gaps, and upgrading pedestrian crossings to current FDOT standards. Included in the scope of services are survey and geotechnical services for roadway cores. The total length of roadway within the project area is approximately 10,560 LF (2.0 miles). Through Work Order 1 issued March 5`t`, 2019 Atkins has developed Construction Plans, Specifications and Cost Estimate for the propose improvements. This scope of work for additional services is for redesign work required by FDOT as noted below: SECTION 1 SCOPE OF SERVICES TASK 1: SURVEY UPDATE Based on FDOT comments of the 90% Plans the County provided additional information on the existing right of way location., particularly at and along the intersections of 61 Avenue from 17t' Street north to 21 St Street including the north right of way line of 21St Street. The proj ect surveyor coordinated with the County Surveyor to obtain this information and updated the project survey. TASK 2: ROADWAY AND SIGNAL PLAN REDESIGN The original intent was that the design of proposed improvements that would require additional right of way and/or easement(s), including temporary construction easements in locations where right of way was limited for the construction of sidewalks, miscellaneous drainage improvements and construction access. Atkins coordinated with County staff on those locations and provided sketches for the County's use in contacting the landowners. Following FDOT review of the project FDOT comments required removal of this work and required all work to be done from within the existing right of way. Atkins coordinated with the IRC staff and the project surveyor on the right of location. Based on County staff direction to remove all work outside the right of way Atkins revised the construction drawings after the 90% submittal. This direction was made after receipt of county staff review comments for the 90% plans and while Atkins was finalizing the 100% construction documents for resubmittal to the county.
