Description
The Department of the Interior’s Bureau of Reclamation is conducting market research for a major water‑resources project on the San Joaquin River. The effort involves constructing a bypass channel around Mendota Pool, a north wing dam and levee, a bypass control structure, fish ladder, auxiliary water supply, fish screen, and associated O&M and controls facilities (Phase 1). Phase 2 adds a head‑works structure, canal, siphon and pipeline to replace existing intakes. Designs are roughly 90 % complete for Phase 1 components and 30 % for Phase 2. The agency seeks industry feedback on delivery‑method options (design‑bid‑build vs. design‑build or hybrid), risk identification, schedule compression, and technical details such as geotechnical verification, hydraulic structures, logistics, labor, and long‑lead‑item procurement. Responses are due by 8 Aug 2026; full RFI responses are due 8 Sep 2026. The overall construction magnitude is estimated between $225 M and $300 M, with construction anticipated to begin in 2027 and first‑phase operation targeted for spring 2030.
• Project scope: bypass channel, levee, control structure, fish passage facilities, auxiliary water supply, O&M building (Phase 1); head‑works, canal, siphon/pipeline (Phase 2).
• Design status: ~90 % complete for most Phase 1 items; ~30 % for Phase 2.
• Key decision: DBB baseline vs. DB or hybrid delivery; risk allocation and schedule impacts.
• Information sought: top design/construction risks, design‑completion needs, construction sequencing, in‑water work windows, long‑lead‑item lead times, labor‑shift considerations, PLA impact.
• Timeline: responses to questions by 28 Aug 2026; full RFI response by 8 Sep 2026; construction start 2027; operational target spring 2030.
• Budget: $225‑$300 M total project cost.
