About this file
This document provides details on a pre-solicitation notice for a federal contract opportunity for maintenance dredging services. The U.S. Army Corps of Engineers Engineering District Portland is seeking dredging services for the West Coast from January through December 2024, as outlined in solicitation number W9127N24B0003. Interested parties can review the 17MB public plans file titled WCHOP24_PLANS_Public_Review.pdf for additional specifications on the required dredging work. Responses to the pre-solicitation notice are not yet being accepted, as the formal solicitation process for this opportunity is still in development by the agency. Upon finalization and release of solicitation W9127N24B0003, vendors will be able to submit proposals and bids for consideration for a contract award for the 2024 maintenance dredging season on the West Coast.
