Request For Statements Of Qualifications For Regional Water Supply Engineering And Related Services

The Sonoma County Water Agency is soliciting Statements of Qualifications under solicitation TW 25/26-003 to establish a list of qualified engineering firms for regional water infrastructure services over the next five years. This initiative focuses on the planning and design of large reservoir infrastructure, specifically targeting improvements at Coyote Valley Dam/Lake Mendocino and a potential secondary outlet for Lake Sonoma to address water supply challenges following the discontinuation of the Potter Valley Project. The agency seeks firms with specialized expertise in hydrological, hydraulic, geotechnical, and structural engineering for dams, spillways, tunnels, and hydroelectric facilities, as well as experience in strategic planning and permitting with the USACE and FERC. The selection process is qualification-based rather than cost-based, evaluating firms on the thoroughness of their submissions, professional qualifications, and adherence to standard contract terms. A 5% numerical preference is granted to qualified local service providers located and operating within Sonoma County. Selected consultants will be responsible for design development across 60%, 90%, and 99% phases, producing deliverables such as design reports, technical specifications following CSI MasterFormat 2018, and AACE Class 1 cost estimates. All work must comply with Sonoma Water Design Standards, the Sonoma County Living Wage Ordinance, and California prevailing wage laws, requiring firms to be DIR-registered. Deliverables must be submitted electronically in PDF, Microsoft 365, and native AutoCAD Civil 3D formats. The submission deadline for Statements of Qualifications is July 22, 2026, at 2:00 p.m. via email. While specific project budgets and schedules are to be determined, the resulting agreements will function as an IDIQ-style arrangement where firms are prequalified for future task orders. Key contractual requirements include broad indemnification, professional liability insurance naming the agency as an additional insured, and strict controls over the substitution of key personnel.
