Indefinite Delivery Contract N0002425D4349

The Naval Sea Systems Command (NAVSEA) awarded an Indefinite Delivery Multiple Award Contract to Southcoast Welding & Manufacturing, LLC for non-critical systems engineering support under the OPW Lot 2 vehicle, with a ceiling value of $1.14 billion and an ultimate completion date of September 1, 2033. The contract was awarded on September 2, 2025, with no small business set-aside applied. The underlying procurement was initiated through a pre-solicitation notice posted in July 2024 for a potential Indefinite Delivery Indefinite Quantity Multiple Award Contract to support Chief of Naval Operations availabilities on fast attack submarines across the Navy's four public shipyards. The work is categorized into two tiers—Lot 1 (Critical) and Lot 2 (Non-Critical)—with Lot 2 encompassing discrete production, non-discrete production, and other production work related to repair, maintenance, and modernization of nuclear-powered attack submarines. The contract was structured with a five-year base period and three option years, with provisions for rolling admissions to add additional contractors periodically.

Southcoast Welding & Manufacturing, a Chula Vista, California-based manufacturer specializing in structural steel and aluminum fabrication, welding, and machining services, is the awardee and will perform work at its Chula Vista location. A delivery order valued at $5,000 was issued on September 11, 2025, with completion scheduled for October 15, 2025, utilizing firm fixed-price pricing. The contractor brings established expertise in naval vessel maintenance and repair through its three existing Indefinite Delivery/Indefinite Quantity contracts totaling over $550 million with NAVSEA and the National Oceanic and Atmospheric Administration, positioning it to execute complex non-critical systems engineering support for the Navy's submarine maintenance and modernization requirements.
