The Supervisor of Shipbuilding, Conversion, and Repair, USN, Gulf Coast (SSGC) intends to conduct a sole source procurement for Post Shakedown Availability (PSA) planning and support services for DDG 119. Requirements include planning, engineering, management, material identification, material procurement and kitting, Integrated Logistics Support (ILS), and emergent work to plan support the PSA for DDG 119. The place of performance for these requirements will be Pascagoula, MS. Work is projected to start in March 2020 with an expected duration through approximately August 2021. These requirements will be procured as an order under the terms and scope of Basic Ordering Agreement (BOA) N00024-16-G-2303 issued to Huntington Ingalls Incorporated, Ingalls Shipbuilding (Ingalls), 1000 Access Road, Pascagoula, MS 39568. The work must commence prior to the date the shipyard is required to provide final drawings and related data for construction of the individual ship to the Navy.
