About this opportunity
The Department of the Army Corps of Engineers Los Angeles District is procuring emergency dredging services for Naval Weapons Station Seal Beach to maintain the inner approach channel at the entrance to Anaheim Bay. The project requires dredging approximately 80,000 cubic yards of sediment from challenging open ocean conditions and placing the material within two separate disposal sites. The work must maintain the channel to a design depth of -41 feet Mean Lower Low Water and minimum width of 280 feet between arrowhead jetties to ensure navigational safety for Navy warships. The project operates in a high-energy wave environment with typical wave heights exceeding 5 feet and extremely long wave periods, with potential for larger waves during storm events. The solicitation has undergone multiple amendments, with the most recent Amendment 0002 adding and removing clauses while updating the bid due date to September 4, 2025.
This opportunity uses no set-aside designation and is open to full and open competition under NAICS code 237990 for Other Heavy and Civil Engineering Construction. Two bidders submitted proposals during the bid opening on September 4, 2025: Curtin Maritime Corp. from Long Beach, California with the lowest bid of $1,990,205.86, and Manson Construction Co. from Seattle, Washington at $2,356,750.00. The Independent Government Estimate was $3,611,250.00, indicating both bids came in significantly under the government's anticipated cost. The contract includes four line items covering mobilization and demobilization, dredging operations for two different placement areas totaling 69,000 cubic yards, and environmental surveys and monitoring. Work will be performed at Naval Weapons Station Seal Beach located at 800 Seal Beach Blvd, Seal Beach, California, with portions extending into Pacific Ocean waters beyond the protective jetties.
