Shipboard Habitability Ship Systems Alteration Development and Installation

Naval Sea Systems Command established a Master IDIQ on May 3, 2021, for engineering and technical support services in shipboard habitability systems—berthing, sanitary, food service, medical, dental, and personnel service spaces—with a shared ceiling of $986.3 million and an ordering period that closed on May 12, 2026. The vehicle is closed to new orders.

The IDIQ was set aside for Total Small Business at the vehicle level but task-order awards show a mixed utilization pattern: 26% of the 53 orders placed are designated Total Small Business, while 74% are unrestricted competitive awards. This mix reflects the Navy's approach to allocating work across both set-aside and open competition after vehicle establishment.

Delphinus Engineering dominates the award portfolio with 20 orders valued at $98.9 million in combined potential value—roughly 60% of all task-order value—followed at distance by QED Systems ($20.2 million across 8 orders) and Tecnico Corporation ($19.9 million across 9 orders). These three firms hold 95% of combined potential value. The remaining five awardees capture the tail, indicating a highly concentrated competitive landscape.

All ordering activity flows to Naval Sea Systems Command itself (51 orders, $147.7 million) and United States Pacific Fleet Forces (2 orders, $15.9 million). Ordering momentum declined sharply in the final years of the vehicle's life: 16 orders in 2022, declining to 2 in 2026 (through February). The Navy has obligated $156.5 million of the $163.6 million combined task-order potential value—96% commitment.

Task orders are priced as cost-plus-fixed-fee delivery orders ranging from under $25 thousand for narrow design surveys to $24.5 million for a food service equipment replacement on USS John C. Stennis. Typical orders supporting alteration installation team work cluster in the $3 million to $5 million range and span 12 to 24 months. Work spans worldwide locations, with operational performance on individual vessels (CVN and DDG class ships predominate in recent awards) and administrative oversight at Naval Sea Systems Command.

Engineering and technical support services for Habitability systems. Work is to consist of material procurement, tooling, equipment, labor and facilities for the design, installation and repair of Habitability Spaces, Facilities, Distributive Systems, Fixtures and Equipment. Habitability Spaces and Facilities consist of living, leisure and community spaces; sanitary spaces; food service and mess area spaces; medical and dental spaces; personnel service spaces i.e., barber shop, ship store, post office, disbursing, legal, gym, religious ministry and welfare, vending machine area; laundry and dry cleaning facilities; offices; workshops, laboratories and tool issue rooms; stowage, storerooms and store issue rooms.
