This modification extends an existing Department of Homeland Security task order for Systems Engineering and Technical Assistance (SETA) support to prevent a service gap while a recompete is finalized. The work supports the Office of Science and Engineering’s Systems Engineering and Standards Division, including R&D, acquisition programs, and human systems integration. The extension procures additional in-scope work and extends the period of performance. No specific budget amount, performance location, or non-bid timeline is mentioned in the description. The primary purpose is to maintain continuity of support during the recompete process.
