This pre-solicitation notice announces an upcoming invitation for bids for mechanical dredging services on the Rogue River in Oregon. The U.S. Army Corps of Engineers Portland District intends to issue solicitation number W9127N22B0004 to dredge approximately 340,000 cubic yards as a mandatory line item, with optional items of up to 20,000 cubic yards depending on needs and funding. A pre-bid meeting will be held on December 16th, with the solicitation expected to be released on January 28th and bids due 30 days after. The work window for dredging is June through October 2022 and will require water quality monitoring. The estimated value is between $5-10 million.
