SJCDPW-RFP-19-02
The San Joaquin County Department of Public Works (SJCDPW) requests technical proposals from qualified consulting engineers to undertake, perform, and complete tasks set forth in Request for Proposals SJCDPW-RFP-19-02. The selected consultant firm (CONSULTANT) will perform professional and technical engineering services (SERVICES) for the Grant Line Road Realignment Project (PROJECT). The purpose of PROJECT is to provide enhanced traffic safety, improve operation of the roadway network, and meet future traffic demands by reducing congestion in the area in and around the community of Banta. County adopted an Environmental Impact Report in December 2018 that identifies a preferred alternative for the PROJECT. Phased work effort: The requested SERVICES will be conducted in two phases. CONSULTANT will complete Phase One first. Phase Two work will be contingent on the outcome of Phase One. Phase One work includes preparation of a Grade Separation Analysis (GSA) in cooperation with Union Pacific Railroad (UPRR), and coordination with the California Public Utilities Commission (CPUC), for a new at-grade crossing per the preferred alternative alignment. Additionally, Phase One requires coordination with UPRR/CPUC for closure of up to three existing at-grade crossings. If the GSA determines a new at-grade crossing is infeasible, the County may opt to refrain from moving forward with Phase Two work. The deadline for submitting technical proposals to SJCDPW will be no later than 4:00 p.m. on Friday, May 17, 2019. SJCDPW’s standard business practice strives to ensure that a consultant’s professional qualifications meet the needs and services to be performed, the payment method is appropriate, and the cost is fair and reasonable to the public agency. The specific requirements set forth in SJCDPW-RFP-19-02 should be closely examined and followed by those consultant firms interested in submitting statements of qualifications.
