Grove Road Bridge The Grove Road Bridge over the Sand Creek Arm of Lake Decatur has significant pack rust on the outer I-beams,a severely delaminated concrete deck,and rocker bearings that are over rotated(see photo sheet in Appendix A). Under the National Bridge Inspection System(NBIS)guidelines required by the Federal Highway Administration,the superstructure has a rating of "5"(Fair Condition)on a scale of 0-9(O=Required Closure,9=New). The bridge's deck condition has a rating of 3 (Serious Condition). The Bridge Substructure has a rating of "6". While the overall condition of the Grove Road Bridge is in fair condition and the bridge is currently safe for traffic with no restrictions,the Bridge Condition Report completed in 2019 recommended replacement of the entire structure rather than rehabilitation due to the life cycle costs. Request for Proposals On May 19,2021,the City issued a request for proposals and qualifications to provide design services to rehabilitate the Garfield Avenue Bridge over 22nd Street and the Grove Road Bridge. Proposals were received on June 16,2021. Six firms submitted formal statements of qualifications. Public Works Department staff reviewed the proposals and recommended WHKS &Co.,of Springfield,IL,as the firm best able to serve the City in performing the requested design services. Engineering Services Agreement The Grove Road Bridge design services are to prepare design drawings and obtain IDOT&FHWA approvals to perform the bridge construction work in 2023 or 2024 depending on when the City receives environmental clearances from IDOT. The narrow bridge does not allow for phased construction and will require the full closure of Grove Road throughout the construction. The replacement is anticipated to be completed during one construction season to minimize impact. The Design Services Agreement will include the following services: 1. Perform topographic and geotechnical surveys of the project site. 2. Prepare a hydraulic report for the Grove Road Bridge to identify any effect the structure may have on Sand Creek Arm of Lake Decatur and determine if there are scour concerns with the structure footings. 3. Appy and receive State,Corp or Engineers,IDNR and Environmental clearance permits. 4. Complete the design for the bridge and approach and prepare construction plans for bidding. 5. Prepare the project specifications with the bidding information required by IDOT. 6. Coordinate the construction impacts with area schools and residents. 7. Provide construction bidding assistance to the City as needed. The proposed total fee is $221,181 which will be paid with Rebuild Illinois funds.
