Simpson Lane Bridge - Rehabilitation versus Replacement Feasibility Study

General work description:

The consultant will prepare a planning/feasibility study for the Simpson Lane Bridge to provide the County with an analysis of the existing bridge to determine alternatives between rehabilitating the existing bridge and options for replacing the bridge. The outcome of this study will be utilized to streamline the PE phase of the project through the Highway Bridge Program so the solution to the scour critical bridge will already have been determined and corroborated by the Caltrans SM&I team.

Background

The County of Yuba is accepting proposals from qualified professional engineering consultants for the preparation of a full Rehabilitation versus Replacement Study (planning/feasibility study) for the Simpson Lane Bridge. The project will allow the County of Yuba to evaluate the alternatives between rehabilitating the existing bridge and replacing the bridge and also complete the Rehabilitation vs. Replacement Study identified in the County’s 2020 Scour Evaluation – Plan of Action, found here: https://www.yuba.org/departments/community_development/public_works/documents.php. This effort is federally funded through the Department of Transportation and Federal Highway Administration FY 2024 Bridge Investment Program – Planning Grant. Information about the Bridge Investment Program can be found at: https://www.fhwa.dot.gov/bridge/bip/.

• Evaluation Process and Selection Criteria —

  After the period has closed for receipt of proposals, Yuba County will open and examine each proposal to determine compliance with the requirements specified in the Request for Proposal (RFP). The County will eliminate any proposal that does not meet the format requirements from competition and will return the proposal to the Consultant. The County may reject any proposal if it is conditional, incomplete, or contains irregularities. The County may waive an immaterial deviation in a proposal. Waiver of an immaterial deviation shall in no way modify the RFP documents or excuse the Consultant from full compliance with the contract requirements if awarded the contract.

  The selection panel will review each proposal that meets the format requirements. Panel members will individually evaluate each technical proposal in accordance with the evaluation criteria included in the attachments.

  The panel members will meet to tally and average scores for each proposal. The panel will rank the technical proposals based on the average scores and will notify the Consultants in writing. The selection panel will prepare the final ranking based on the criteria contained herein. Based on the rankings, the County may decide to conduct interviews with the top two ranked firms or may select a consultant directly from the final rankings.

  The County will then enter into negotiation with the top ranked Consultant. If agreement is reached, the firm will be recommended for award subject to approval by Public Works Staff and/or the Board of Supervisors. If the County cannot reach an agreement with the top ranked firm, the County will close negotiations and may enter into negotiations with the second ranked firm.

  This Request for Proposal does not commit the County to award a contract, to pay any costs incurred in the preparation of a proposal for this request, or to procure or contract for services. The County reserves the right to accept or reject any or all proposals received in response to this request, to negotiate with any qualified firm, or to modify or cancel in part or in its entirety the Request for Proposal if it is in the best interest of the County to do so.

  All products used or developed in the execution of any contract resulting from this Request for Proposal will remain in the public domain at the completion of the contract.

  Upon approval of the selected Consultant by County, a mutually acceptable price will be negotiated, a written Agreement will be prepared, executed by the Consultant, and reviewed by the County for approval and execution. The Consultant will begin work immediately upon execution of the Agreement by the County.

  Any proposer may withdraw or modify their proposal received prior to the time and date specified above by written request of the proposer. The County must receive any modified proposal prior to the specified deadline or the County will not consider the modified proposal. The County will return any proposals received after the time and date specified above to the proposer.

  The County will reject all unsigned proposals or proposals signed by an individual not authorized to bind the prospective Consultant.

  The County reserves the right to reject all proposals and issue another RFP, if necessary.
