About this file

This is a Request for Qualifications (RFQ) issued by the California Department of Water Resources (DWR), Division of Modeling Support Office, in collaboration with the U.S. Bureau of Reclamation Mid-Pacific Region. The RFQ seeks qualified firms to provide engineering services for the development, enhancement, and application of CalSim modeling tools, including CalSim 3, CalLite, CalSimHydro, CS3RimInflow, and the CalSim 3 Historical Hydrology Model (CS3HIST), to support simulation of Central Valley Project (CVP) and State Water Project (SWP) system operations. Work encompasses improving the WRIMS simulation engine, modeling water use for agriculture, urban, and refuge needs, and simulating streamflow and surface runoff. The contractor must also support calibration and validation of CalSim 3 surface and groundwater hydrology. Statements of Qualifications must be received by 2:00 p.m. on September 15, 2026. A mandatory virtual pre-SOQ conference is scheduled for August 31, 2026, at 10:00 a.m., with attendance required for all prospective firms. The contract term is estimated at three years, from December 3, 2026, through December 2, 2029, with options for up to two one-year amendments. This solicitation may result in multiple awards, with up to twelve contracts available—a maximum of three contracts for each of four Specific Areas of Development: System Operation, CalSim Hydrology Development, Groundwater Model and Data Development, and Water Resource Integrated Modeling System and Processing Tools.

Pricing will be negotiated based on the firm's true and actual cost with a fixed profit rate established by DWR, along with published escalation rates and subcontractor markups. At the time of selection, the most qualified firm will be instructed to submit financial documents and rate sheets, including resumes, payroll records, fringe benefits documentation, overhead costs, and compensation policies. DWR will evaluate SOQs submitted for each Specific Area of Development, with firms scoring at least 70 percent of total possible points invited to interview. Following interviews, DWR may award contracts to the three most qualified firms for each area, designating the highest-ranked firm as primary contractor and the second and third-ranked firms as backup contractors. The estimated contract value is between $1,000,000 and $10,000,000. DWR encourages participation by Small Business, Microbusiness, and Disabled Veteran Business Enterprise entities. Submitters must disclose any use of Generative Artificial Intelligence in completing deliverables, with failure to disclose potentially resulting in disqualification. All materials submitted become State property and will not be returned, except non-selected firms' brochures, which may be retrieved after award. DWR reserves the right to cancel or modify the RFQ and is not responsible for any preparation costs incurred by prospective firms.

C. Once the most qualified has been selected by the DWR panel, DWR will notify that respective Firm.

VIII. Negotiations

A. The DWR negotiation process will be based on: Firm’s actual cost with a fixed profit rate that has been established by DWR. See Exhibit E, Additional Provisions for the published profit rate, the annual escalation for the hourly billing rates, and subcontractor mark-up for this contract.

B. At time of selection, up to twelve of the most qualified firms will be instructed to submit their financial documents and rate sheet. The Firm’s submission must be electronic and must be submitted no later than five (5) business days after notification of selection or otherwise determined by DWR. Financial documents will include resumes for all personnel; true and actual payroll records; financial records that support fringe benefits, overhead costs, and general administration;

documentation or records that support costs incurred by utilizing subcontractors;

historical and true records of other direct cost charges; and compensation policies.

Compensation policies will include shift differential policies, holiday policies, and how the Firm’s personnel and subcontractor personnel receive compensation for overtime (hours worked over an established work week). The specific financial documents and format of the rate sheet will be identified during the Mandatory Pre-SOQ Conference (see Section IV) and when the most qualified firm gets notified of selection. The prime Firm will be responsible for submitting the complete financial documents for their personnel, including any subcontractors. Submissions of the Firm’s rate sheet must be provided electronically to DWR on a Microsoft Excel spreadsheet titled RFQ No. 10220250 followed by the name of the Firm as it appears on SOQ. Failure to submit a complete financial documents package or rate sheet may result in termination of negotiations.

C. After the financial documents and rate sheet have been received, DWR will begin to review the documentation to ensure the documents are complete and requested reimbursement is appropriate. Discussions with the most qualified applicant regarding the submitted financial documents, rate sheet, and resumes will occur after DWR’s review in order to determine a cost that is fair and reasonable to the State.

Any missing documentation or comments from DWR will need to be resolved timely;

see Section XI, Time Schedule. If DWR is unable to successfully negotiate a cost agreement with the most qualified Firm, negotiations will begin with the next most qualified Firm, and so on. If DWR is unable to negotiate a fair and reasonable cost with any Firm, DWR may elect not to award the contract and may elect to proceed with a new solicitation.

D. Unsuccessful Firm’s will be notified by DWR following award of the contract.

E. Nothing in this RFQ shall require DWR to award a contract.

IX. SOQ Conditions

In addition to Section VI, Selection Criteria and Section VII, Evaluation Process, the following SOQ conditions apply:

A. Firms must keep the interview selection, interview content, most qualified selection, and contract negotiations confidential until the contract is awarded.

B. Evaluations will be available for public inspection at the conclusion of the selection and award process under the California Public Records Act (Government Code Section 6250 et seq.) and subject to review by the public.

C. DWR considers confidential financial information provided by firms as a part of negotiations to not be subject to the Public Records Act.

D. On March 4, 2022, Governor Gavin Newsom issued Executive Order N-6-22 (the

EO) regarding Economic Sanctions against Russia and Russian entities and individuals. “Economic Sanctions” refers to sanctions imposed by the U.S.

government in response to Russia’s actions in Ukraine, as well as any sanctions imposed under state law. By submitting a bid or proposal a Statement of Qualifications (SOQ), Contractor represents that it is not a target of Economic Sanctions. Should the State determine Contractor is a target of Economic Sanctions or is conducting prohibited transactions with sanctioned individuals or entities, that shall be grounds for rejection of the Contractor’s SOQ any time prior to contract execution, or, if determined after contract execution, shall be grounds for termination by the State.
