About this opportunity
The U.S. Army Corps of Engineers San Francisco District is seeking contractors to repair storm-damaged flood control channels in Alameda County, California, under the Zone 7 Flood Control Channels Phase 1 Project. This one-time repair project addresses erosion and bank failures at ten sites along Arroyo Mocho and Alamo Canal (sites G-6 through G-14 and F-11 through F-13) that occurred during atmospheric rivers between December 2022 and March 2023. The repair work involves excavating damaged areas, removing disturbed soil and vegetation, placing rock slope protection at the waterside slope toe, installing soil-filled rock slope protection up to the 10-year water surface elevation, and restoring slopes with compacted backfill followed by erosion control matting and hydroseeding. The contract includes a base performance covering three sites (G-06, G-10, and G-13) with an option for a fourth site (G-14), and all work must be completed within strict environmental windows. The solicitation was originally due June 30, 2025, but was extended to July 3, 2025, at 11:00 AM PST, with a public bid opening scheduled for 11:30 AM PDT the same day.
This procurement is designated as a 100% small business set-aside under NAICS code 237990 (Other Heavy and Civil Engineering Construction), with an estimated contract value between $5,000,000 and $10,000,000. The base contract has a performance period of 106 calendar days, extending to 120 days if the option is exercised, with in-water construction restricted to the period between June 15 and October 15. The project involves restoring flood control channels with earthen slopes previously constructed to 2H:1V grades and channel heights ranging from 15-30 feet. A pre-bid site visit was conducted on June 12, 2025, with multiple contractors attending including Dutra Group, SUULTAAQ, Remedial Transportation Services, Teichert Construction, Maloney-Odin Joint Venture, and Odin. The work will be performed in Alameda County, California, and is funded under Public Law 84-99, which authorizes the Corps of Engineers to repair flood control works damaged by floods or other natural disasters.
