What Is GSA OASIS+?
OASIS+ is a suite of six multiple-award, indefinite-delivery/indefinite-quantity contracts with a five-year base period and a five-year option term.
The contract program is designed to help federal agencies meet their procurement requirements for services-based solutions. It covers eight domains: management and advisory; technical and engineering; intelligence services; R&D; logistics; environmental; facilities; and enterprise solutions.
The program seeks to meet agencies’ non-IT service requirements, promote competition among service contractors and eliminate barriers to entry to maximize small business participation.
In October, GSA released the lists of apparent rolling awardees under the OASIS+ Unrestricted track and five small business set-aside tracks — Total Small Business; 8(a) small business; women-owned small business; HUBZone small business; and service-disabled veteran-owned small business.
What Changes Are Coming With OASIS+ Phase II?
Phase II builds on the initial rollout of OASIS+, adding five new service domains to the contract vehicle’s existing scope. This expansion increases the total number of domains across all six OASIS+ contract categories to 13, allowing agencies to purchase a more diverse range of professional services from a broader pool of qualified contractors.
Under Phase II, the new domains include:
- Business administration
- Financial services
- Human capital
- Marketing and public relations
- Social services
“GSA continues to deliver on President Trump’s priority to streamline and consolidate federal procurement to deliver savings to American taxpayers and improve the buying experience for federal agencies,” said Josh Gruenbaum, commissioner of GSA’s Federal Acquisition Service and a previous Wash100 awardee. “This expansion provides federal agencies with a broader range of comprehensive professional service solutions and creates new opportunities for qualified industry partners.”
GSA is also transitioning all six OASIS+ solicitations to a continuous open solicitation model by Jan. 12, allowing vendors to submit proposals on a rolling basis rather than during limited submission windows.
How Did Industry Input Shape OASIS+ Phase II?
GSA sought input from industry partners during Phase II development. In mid-2025, the agency issued a request for information to gather feedback on capabilities that would inform the structure and evaluation criteria for the five new domains. Responses helped shape the domain definitions and scoring considerations ahead of the Phase II rollout.
What Are OASIS+ Draft Scorecards & Contract Modifications?
As part of Phase II preparation, GSA issued on Dec. 19 a pre-amendment notice releasing draft scorecards, along with details regarding bilateral modification of all existing OASIS+ contracts.
The draft scorecards provide early insight into evaluation criteria, allowing companies to assess their potential standing by evaluating their qualifications in each of the 13 domains. Meanwhile, the modification includes regulatory updates and expansion of scope with the addition of five new domains.
GSA shared the materials through the OASIS+ Interact platform to give industry additional time to align capabilities, documentation and past performance ahead of the solicitation reopening as the contract program enters Phase II.
