Exhibit A Task 00100 Survev and Field Work(overview) Survey work will include topographic surveys both Lidar and Conventional. Work will involve surveys on railroad property and will require railroad coordination,access permits and flagger operations and railroad insurance. Survey field work will also require environmental surveys including ground sampling and boring operations in support of environmental reports and memos. Survey work will be required for ROW surveys in support of plats and legal preparation. Field work will be required for geotechnical borings in support of geotechnical reports. Access to properties will be required and access wilI be coordinated through the City and or the City property negotiator. An access letter from the City explaining the project and the need for surveys will be drafted and used for field work. Task 00200 Phase I Undate—VE CR ABC(overview) The Phase I design will require modifications as the project was broken up into three segments and the north segment will need to tie into the existing roadway geometty near the existing railroad subway. Though initial Value Engineering and Constructability Reviews further cost savings and design changes may be identified with the overall goal of designing the project to meet the funding limits and minimize impacts to the motoring public. These modifications will be submitted to the City and IDOT for approval. Accelerated Bridge Construction techniques will be investigated under this task. It is assumed that the traffic volumes in the Phase I report will not be modified and will be used for rework of the geometry of the revised Phase I design including Plan and Profiles, IDS and TSL's. Roadwav GeometrX The roadway geometry will be updated to include horizontal geometry tie in between the existing and proposed improvements of Brush College Road near the existing Norfolk Southern Railyard overpass. This will include profile modifications to tie into the existing underpass profile grade. Optimize Current Bridge Design The objective of this task is to take a fresh look at the current phase I bridge design to optimize selected bridge type to evaluate potential cost saving options. Revise Type, Size and Location(TSL)Plans Based on the above optimization to the bridge structure,it may be necessary to revise the cunent TSL plans to include feasible modifications. Value En ineerin�(VE)and Constructability Reviews(CR): Prior to milestone submittals(Preliminary and Final),construction documents will be reviewed by senior engineers from AECOM,WHKS and QEI(to be led by AECOM)with extensive experience in design and construction of similar bridges. The intent of this review is to make suggestions to improve the design and details relative to generally utilized construction practices. Scope 9-21-18 A_2
