Summary
The Engineering committee approved consolidation and placement of five items including a $6.75 million extra work order for Walsh Construction on the I‑490 railroad bridge, a $22.78 million bridge design award to AECOM, multi‑year consulting renewals and a $5 million amendment to extend fiber maintenance services.
The Illinois Tollway's Engineering, Planning and Development Oversight Committee on Dec. 18 approved consolidation and placement of five engineering items on the full board agenda, including a major change order tied to the I‑490 corridor and several multi‑million professional services actions.
Chief Engineering Officer Manar Nasheff described a $6,750,000 extra work order on contract I214732 with Walsh Construction Company to redesign a railroad bridge pier and add two additional bridge piers for the 1,800‑foot rail bridge over a busy CPKC intermodal yard. Nasheff said Canadian Pacific recently installed a new track that conflicted with planned bridge pier construction and that soil conditions required additional steel piling for other piers; the work will require specialized methods to avoid disrupting active rail operations.
The committee also recommended award of bridge design services to AECOM Technical Services Inc. for $22,779,840.95 to design reconstruction work on the Tri‑State Tollway between 107th Street and Harlem Avenue. Commitments to meet DBE and veteran participation goals were noted in the presentation.
Two foundational contract renewals were presented: a $57.4 million renewal with WSP USA for consulting engineer services (contract RR219982) and a $12.75 million renewal with CDM Smith for traffic engineering services (contract RR219981). Both renewals were described as required under the Tollway's trust indenture and necessary to support ongoing capital program activities.
Finally, the committee recommended a $5,000,000 amendment to extend fiber‑optic maintenance and management services with Adesto LLC while a new RFP is completed; the Tollway's fiber network is approximately 329 centerline miles and the contract supports inspections, design review, locating and coordination with third‑party lessees.
The engineering items were consolidated for consideration and the committee approved placement of items 1–5 on the full board agenda. The board later accepted the committee recommendation during its Dec. 18 session. Committee materials and presenters emphasized the need to coordinate closely with railroads, utilities and local agencies to avoid disruptions and to meet federal and local requirements for projects that leverage grant funding.
