B--CalSim 3 Model Development & Operations Analysis

The contract supports the development, improvement, and operational analysis of the CalSim 3 model, a critical tool used by the Bureau of Reclamation and the California Department of Water Resources to simulate water allocation, exports, rescheduling, and other operations within the Central Valley Project and State Water Project. The work is performed under a Time and Materials contract with a base period from June 15, 2026, to June 14, 2027, and four one-year option periods extending through June 14, 2031, with a possible six-month extension under FAR 52.217-8. The contractor is responsible for delivering technical outputs including WRESL code, post-processing tools, analytical reports, training materials, and documentation, all submitted via secure platforms such as SharePoint. Work is conducted primarily at the contractor’s facility with weekly coordination meetings required, and deliverables must meet strict timelines, including interim submissions within two business days of request. The contract ceiling is $1,600,000, with no detailed unit pricing provided, and payment is processed electronically through the Invoice Processing Platform, with invoicing mandated by DOI-AAAP-0028. The contract imposes rigorous personnel and security requirements, including U.S. citizenship for all personnel or documented legal residency, mandatory government-issued identification (PIV, DOI Access Card), and adherence to NISPOM standards for handling classified or controlled information. Subcontractors are bound by the same obligations, and the prime contractor must flow down all applicable clauses. Organizational conflict of interest mitigations prohibit unauthorized public release of contract information, require immediate reporting of information breaches, and restrict access to classified materials even if available elsewhere. Small business participation is strongly incentivized with subcontracting goals totaling 45.87% for Small Businesses, and additional targets for SDVOSB, WOSB, HUBZone, SDB, and ISBEE. Evaluation is based on a trade-off process prioritizing technical approach and contractor experience, followed by past performance, price, and small business participation, with no fixed weights applied. The solicitation mandates electronic submission of a capped 50-page technical proposal and completed attachments via email to the Contracting Officer by May 20, 2026, and includes standard FAR clauses covering whistleblower protections, trafficking prohibition, employment eligibility verification, sustainable products, data rights, payment procedures, and contract changes under Time and Materials terms.
