About this IDV
The Naval Sea Systems Command (NAVSEA) awarded a single-award Indefinite Delivery Contract to Tridentis LLC on February 21, 2019, for comprehensive engineering services supporting shipyard operations and naval vessel maintenance. The contract has a $40 million ceiling value with an ultimate completion date of February 14, 2027. The underlying solicitation, posted in April 2018, sought multi-discipline shipyard engineering, planning, and design services to support the Puget Sound Naval Shipyard and Intermediate Maintenance Facility in Bremerton, Washington. Services encompassed in the contract include ship installation drawing (SID) development, ship specification requirements data sheet (SSRD) creation and updates, technical manual specifications development, shipcheck and habitability inspections, computer-aided design (CAD) drafting and modeling, and vessel system documentation across multiple naval platforms. The contract was not set-aside and represents a firm-fixed-price vehicle for delivering specialized maritime engineering support to the Department of Defense.
The contract has generated substantial delivery order activity, with task orders totaling approximately $20.2 million awarded through September 2025 across diverse naval vessels including aircraft carriers (USS Abraham Lincoln, USS Nimitz), landing ship docks (USS Carter Hall, USS Rushmore, LSD-44, LSD-47, LSD-49, LSD-51, LSD-52), and auxiliary vessels (YRBM15, YRBM50). Performance locations have been distributed across Bremerton, Washington (the primary location of the shipyard), Alexandria, Virginia (Tridentis's corporate headquarters), San Diego, California, Japan, and Portsmouth, Virginia. Work executed under delivery orders reflects the spectrum of engineering support required for fleet maintenance and modernization, ranging from technical documentation updates to comprehensive shipcheck services and system interface drawing development. This contract vehicle enables NAVSEA to procure responsive engineering services supporting its core mission to engineer, build, buy, and maintain the Navy's ships and combat systems.
