One Acquisition Solution for Integrated Services Plus - Unrestricted (OASIS+ Unrestricted)

GSA Federal Acquisition Service awarded the One Acquisition Solution for Integrated Services Plus - Unrestricted (OASIS+ Unrestricted), a multiple-agency Master IDIQ with no set-aside for professional and technical services, and ordering remains open through December 5, 2034. The vehicle was established December 6, 2024, and originated from solicitation 47QRCA21N0001. Roughly eight years and one month of ordering authority remain. Ordering momentum is strong: 41 task orders were awarded in 2025 and 113 in 2026 to date, for 154 orders overall. Combined task-order potential value is $7.29 billion, of which $777.7 million (11%) is obligated.

All 154 task orders carry the No Set-Aside Used designation, and 80 distinct primes hold awards. Deloitte Consulting LLP leads on order count with 18 orders and $126.6 million combined potential value, followed by Booz Allen Hamilton Inc. (9 orders, $724.7 million) and General Dynamics Information Technology, Inc. (4 orders, $345.6 million). By value, Caci, Inc. - Federal (3 orders, $1.54 billion) and Leidos, Inc. (3 orders, $431.9 million) lead. The five largest primes by order count account for 25% of task orders, so activity is spread across a broad field beyond the leaders.

Department of Homeland Security Customs and Border Protection (10 orders) and the Department of Health and Human Services Centers for Disease Control and Prevention Pittsburgh (10 orders) each place the most orders. The Department of Homeland Security US Coast Guard (9), the Department of the Air Force Space Command (9), and the Department of Health and Human Services Administration for Children and Families (7) follow. These five customers account for 29% of orders, with 72 distinct customer agencies overall. The Administration for Children and Families orders carry the largest value among them at $402.2 million.

Recent awards cover survey and evaluation research for Health and Human Services, engineering and R&D support, aviation and simulation services, cybersecurity exercise support, intelligence and modeling support, and infrastructure consulting.

Recent orders are mostly firm fixed price or time and materials, and most run into the 2028 to 2032 period.
