RFQ # 10209281

The California Department of Water Resources (DWR) has issued Request for Quote (RFQ) #10209281 for seismic modeling services targeting the California Central Valley. The primary objective is to develop a comprehensive seismic velocity model that will enhance understanding of the State Water Project's (SWP) vulnerabilities during potential earthquake events. Specific deliverables include collecting geological and geophysical data, creating a 3D velocity model with uncertainty estimates, developing isosurfaces for specific shear-wave velocities, and registering the model with the Statewide California Earthquake Center's Unified Community Velocity Model platform. The contract is anticipated to run from September 1, 2025, through August 31, 2027, with a potential one-year extension option. Responses are due by July 15, 2025, at 12:00 p.m. PT, and the evaluation process will prioritize technical capabilities, focusing on bidders' experience in seismic velocity modeling, geological analysis, and professional qualifications. The contract will be awarded to the lowest-cost bidder meeting all administrative and technical requirements.

The RFQ includes specific set-aside and preference provisions, most notably a mandatory Disabled Veteran Business Enterprise (DVBE) participation component and potential small business preferences. Bidders must submit comprehensive documentation, including certifications, references, and a detailed cost worksheet. The anticipated budget for this contract is $350,000, and quotes must not exceed this amount. While no incumbent vendors are specifically mentioned, the project requires significant technical expertise in geological data analysis, seismic modeling, and geophysical mapping. Prospective contractors will need to demonstrate advanced capabilities in creating complex velocity models and understanding seismic risk assessment methodologies. The procurement appears designed to encourage participation from specialized technical consulting firms with expertise in geological and seismic engineering, with particular emphasis on supporting diverse and veteran-owned businesses through its procurement structure.
