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

GSA Federal Acquisition Service awarded One Acquisition Solution for Integrated Services Plus (OASIS+) Unrestricted, an unrestricted multiple-award IDIQ, on December 6, 2024, with ordering authority extending through December 5, 2029. The vehicle carries a shared ceiling of nearly $1 trillion and has issued 78 task orders totaling $3.34 billion in combined potential value, with $317.5 million (9%) obligated as of mid-June 2026.

Task-order activity remains strong. Ordering began in March 2025; the portfolio now averages 39 orders per year. The 50 prime contractors and 45 customer agencies indicate broad market participation. Deloitte Consulting LLP leads by order count with 16 awards valued at $117.6 million combined potential, followed by Booz Allen Hamilton Inc. (5 orders, $114.3 million). Leidos, Inc. dominates by potential value with 2 orders worth $271.9 million, including a single mega-order for $1.815 billion in geospatial integration work. The top five primes collectively hold 37% of awarded orders and 19% of combined potential value; the tail extends across dozens of smaller contractors, indicating genuine competitive fragmentation rather than concentration.

Customer demand is similarly dispersed. Department of Homeland Security Customs and Border Protection leads by order count (6 orders, $52.3 million potential), with DHS US Coast Guard and Department of the Air Force Space Command each at 5 orders. No single agency dominates; DHS accounts for roughly 32% of orders across multiple components.

All 78 task orders carry an unrestricted (no set-aside) designation, reflecting the vehicle's competitive structure. Recent task orders span typical federal services scopes—infrastructure consulting, data analytics, personnel support, strategic planning, engineering, geospatial intelligence, and advisory work. Pricing structures reflect scope diversity: firm fixed price predominates, but time-and-materials and cost-plus-fixed-fee awards appear on larger, less-defined efforts. Task-order ceilings range from tens of thousands for discrete support work to over $1.8 billion for enterprise platform efforts; typical durations run 12 to 60 months.

Three years and four months of ordering authority remain. The combination of strong early momentum, multi-billion-dollar capacity, dispersed customer and prime bases, and non-restrictive award structure supports sustained activity.
