BOARD/COMMISSION REVIEW:
N/A
BACKGROUND:
The North Aurora Road Underpass at the Wisconsin Central/CN Railroad Improvement Project (CIP# BR005) is a joint effort between the Naperville Township and the cities of Naperville and Aurora. The scope of the project includes constructing a new bridge structure that will accommodate two through traffic lanes in each direction, left turn lanes into adjacent properties, sidewalk and bicycle facilities, additional street lighting and correction of existing flooding issues.
In December 2016, the City Council awarded Contract 16-135 to perform design engineering services for the improvements to the North Aurora Road Underpass at the CN/Wisconsin Central Railroad to TranSystems Corporation. The consultant is working with staff to complete the improvement plans, coordinate with various utilities, secure permits and provide land acquisition services for properties adjacent to the project.
Construction of the project is expected to begin in 2024 at an estimated cost of approximately $40 million. The Illinois Commerce Commission has increased its contribution from $12 million up to $15 million from the Crossing Safety Improvement Program. Chicago Metropolitan Agency for Planning’s Shared Fund Program has also increased its contribution from $9.8 million up to $20.1 million of federal funding. The balance of the construction costs will be split among the three local agencies.

DISCUSSION:
Change Order #8 is requested to perform multiple items required to complete the project which are outside of the original scope of work. The following items have mainly resulted from ongoing negotiations to develop agreements with Wisconsin Central/CN Railroad, BNSF Railroad, ComEd and other utility companies:
1. Additional project coordination with both Canadian National and BNSF railroad companies, ComEd Transmission Company and the Illinois Commerce Commission (ICC).
2. Additional design services required for engineering plan submittals to IDOT and both railroad companies.
3. Additional design services to revise retaining wall designs and drainage due to ComEd Transmission concerns.
4. Additional project management due to extended project timeline.
The proposed cost of the additional project coordination, design engineering survey work, and right-of-way services required is $134,240.
