About this IDV

Naval Sea Systems Command awarded an indefinite-delivery, indefinite-quantity contract to Marine Group Boat Works, LLC, a total small business set-aside, with a ceiling of $139,482,398.76 on December 30, 2020. This is a multiple-award IDIQ. The contract expires September 28, 2026.

Marine Group Boat Works, located in Chula Vista, California, provides comprehensive maintenance, repair, alteration, and logistical support for naval boats, craft, lighterage, and ancillary equipment up to 200 feet in length. The originating solicitation (pre-solicitation posted March 8, 2019) sought marine boatyard services across multiple Navy commands in California, with capacity to service approximately 100 boats and craft annually. Work is performed at the contractor's Chula Vista facility. Period of performance runs through September 28, 2026 under a bilateral modification extending the ordering period through year five.

Recent task order activity reflects sustained operational tempo. Naval Sea Systems Command issued a $15.5 million delivery order on May 18, 2026 for service and repairs to Yard Repair Barge YRBM-26 under total small business set-aside. Navy Installations Command issued a $367,577.98 delivery order on May 11, 2026 for small boat and port operations support (total small business set-aside). Naval Sea Systems Command issued orders in March 2026 for vessel maintenance and repair work on various craft including ACB-1 ($211,540.27), YC-1677 ($824,868.24), APL-69 tow preparation ($89,379.26), and YRBM-29 extension work ($270,488.63). A $1,145,268.89 order for emergent work on Landing Craft Utility vessel LCU-1627 was issued February 19, 2026. Earlier substantial awards include a $5.95 million delivery order for LCU-1632 maintenance and operational support (September 26, 2025), a $17.5 million delivery order for YRBM-29 overhaul and repair (September 30, 2024), and a $733,907 delivery order for construction of a YON 332 fuel barge (September 22, 2025). All recent orders listed carry firm fixed-price structures at the Chula Vista location.
