About this vehicle
The Department of Homeland Security Science and Technology Directorate established Systems Engineering and Technical Assistance III (SETA III), a master IDIQ, on December 4, 2018 to provide advisory and assistance services supporting research, development, test and evaluation. The vehicle's ordering period closed on June 2, 2024, making it inactive for new task orders as of that date.
The vehicle succeeded the prior S&T RDT&E Systems Engineering and Technical Assistance IDIQ (awarded June 26, 2013). Through November 1, 2023, the most recent task-order award, 31 task orders were issued against SETA III with combined potential value of $494.6 million, of which $368.1 million (74 percent) has been obligated. Ordering momentum was concentrated in 2020 and 2023, with 13 orders awarded in each of those years; activity dropped sharply in 2021 and 2022.
All 31 task orders were awarded as unrestricted (no set-aside), priced as time and materials except one firm-fixed-price order. Recent work includes subject matter expertise support to the Office of Systems Engineering and Technology Centers Division, screening-at-speed AI/ML development, international cooperative programs office services, and office of innovation support. Two orders were terminated for convenience in mid-2023 (Operations and Requirement Analysis Division and Technology Scouting and Transition Division support).
Competition is concentrated: Noblis, Inc. holds 15 of 31 awards totaling $225.1 million in combined potential value, roughly 46 percent of the vehicle total. Mantech SRS Technologies, Inc. (5 orders, $141.7 million) and AECOM Services, LLC (4 orders, $71.5 million) are the secondary players. Science Applications International Corporation holds 7 orders worth $56.3 million. Nearly all orders fund the Science and Technology Directorate itself (30 of 31 orders, $489.9 million combined potential value); one order funded DHS Chief Procurement Officer. Task orders range from $1.2 million to $46 million in ceiling value, typically with multi-year periods of performance extending through 2026 or 2027. The largest recent award was to Noblis for S&T MCS support services (April 2023, $80.1 million ceiling).
