About this file
This document provides details on a forthcoming federal solicitation for hopper dredging services along the West Coast of the United States. The U.S. Army Corps of Engineers Portland District intends to issue an Invitation for Bids for the West Coast Hopper Maintenance Dredging project in 2022, which will include work at Humboldt Bay, CA, the Mouth of the Columbia River spanning OR and WA, and the Lower Columbia River in OR and WA. Bids are due 30 days after the solicitation is advertised in March 2022, with an anticipated value between $25-100 million. Interested parties are invited to participate in a virtual pre-solicitation meeting on January 26th to discuss the draft plans and specifications attached here, which are subject to change prior to solicitation issuance. The solicitation will allow for full and open competition and is open to both small and large businesses, though large businesses must submit a small business subcontracting plan.
