Lead System Design Integrator (LSDI)

The Lead System Design Integrator (LSDI) contract, solicitation FA910126DB004, is a single-source, requirements-type Indefinite Delivery Contract (IDC) awarded to Booz Allen Hamilton Inc. (BAH) by the Air Force Test Center. This firm-fixed-price action serves as a follow-on to the MORPHEUS task order, providing essential commercial engineering, design, and integration services for technically complex national security systems. The scope of work encompasses overall design oversight, model-based systems engineering (MBSE), 3D CAD modeling, verification planning, and configuration management. Performance is centered at Arnold Air Force Base, Tennessee, and begins with a three-month phase-in transition period to ensure continuity of institutional knowledge and uninterrupted system integration. The contract structure includes a five-year base ordering period with three optional one-year extensions, allowing for a total potential performance period of eight years. Awarded under FAR 6.302-1, the sole-source justification is based on BAH's unique proprietary design knowledge and the need to avoid massive cost duplication and schedule delays that would occur if a new vendor were integrated. The procurement leverages the GSA OASIS contract vehicle and includes DFARS 252.217-7028 for over and above work. Key requirements include mandatory certification in the Joint Certification Program (JCP) for security and export controls, with the government maintaining unlimited rights to all fully funded designs.
