Exhibit A <br /> Detailed Scope of Services <br /> Brush College Road at Norfolk Southern Crossing <br /> Phase II Documents <br /> AECOM will prepare contract documents for an overpass carrying Brush College Road over the Norfolk <br /> Southern rail yard in Decatur,Illinois. It is anticipated that the project limits will extend from the channel <br /> just south of Cerro Gordo Street to Logan Street. The scope of work will include the following: <br /> Task 00100—Topotraphic Survey <br /> 1. Coordinate with ADM and perform a detailed survey of their piping system and supports along the <br /> east side of the proposed overpass to determine if the supports will interfere with the proposed <br /> overpass. <br /> 2. Determine height of overhead lines in the area of the project. <br /> 3. Determine vertical clearance under ADM pipelines along access roads to Norfolk Southern rail yard. <br /> 4. Perform additional pick-up survey as needed during the course of the final design. <br /> a. Secure railroad flagging services from Norfolk Southern Railroad and the Canadian National <br /> Railroad for all survey work performed within 25 feet of the railroad track. <br /> b. Acquire right of entry permit from Canadian National Railway for any survey work <br /> performed on their property <br /> 5. Download and process survey data. <br /> Task 00200—Roadwav Desisn <br /> 1. Perform a field check of the project limits. Revise the existing topography file if necessary. <br /> 2. Take pictures throughout the project limits and create a photo log. <br /> 3. Adjust Phase I profiles to comply with ADA requirements giving consideration to construction <br /> tolerances. <br /> 4. Finalize preliminary pavement design from Phase I. Assume five(5)pavement designs: Brush <br /> College Road,E. Marieta Street,Frontage Road,E. Olive Street and N. James Street. <br /> 5. Establish final roadway geometry at"tie-in"points at east and west ends of project. <br /> 6. Revise Phase 1 profiles to match beginning and ending points of the project. <br /> 7. Incorporate closed drainage system from the storm sewer model into roadway design. <br /> 8. Develop horizontal and vertical geometry for the N. James Street improvements between E. Olive <br /> Street and E.Logan Street. <br /> 9. Develop horizontal and vertical geometry for the Olive Street cul-de-sac improvements. <br /> 10. Develop horizontal and vertical geometry for the design of the Frontage Road between E. Hickory <br /> Street and E. Grand Avenue. <br /> 11. Determine sign locations on structures for existing improvements and future improvements at Faries <br /> Parkway. <br /> Scope 4-24-15 A-1 <br />
