About this award
The U.S. Army Corps of Engineers awarded a $33.65 million firm fixed-price definitive contract to Manson Construction Co. for FY25 West Coast Hopper Dredging Mobilization and Demobilization services. The work, performed from May 2025 through December 15, 2025, involves hopper dredge services at multiple West Coast locations including Humboldt Bay, California; the Mouth of the Columbia River in Oregon and Washington; Lower Columbia River in Oregon and Washington; and Coos Bay, Oregon. The contract includes approximately 3.2 million cubic yards of mandatory routine maintenance dredging with an additional optional 1.45 million cubic yards at Coos Bay, along with mandatory water quality monitoring requirements. The procurement was unrestricted with no set-aside designation and was awarded based on competitive bidding through an Invitation for Bids process.
Manson Construction Co., a Seattle-based for-profit marine construction and dredging specialist founded in 1905, is well-positioned as the awardee given its extensive history as a preferred federal contractor for the Army Corps of Engineers. The company currently holds multiple significant indefinite delivery contracts with the Corps of Engineers worth approximately $119 million across the New Orleans and Mobile Districts, as well as a combined $1.32 billion in multiple-award indefinite delivery contracts with Naval Facilities Engineering Command, demonstrating sustained federal confidence in its capability to execute complex maritime infrastructure projects. The Portland District contract represents continued reliance on Manson's specialized hopper dredging expertise for maintaining critical West Coast navigation channels and supporting maritime commerce.
