GSA OASIS+ Phase II Summary

GSA OASIS+ is a $60B+ Best-in-Class (BIC) IDIQ GWAC designed to streamline federal access to integrated professional services across a broad range of mission needs. The vehicle has no single program ceiling, supports task orders of virtually any size, and includes a 10-year ordering period (five-year base plus one five-year option)—helping agencies move faster using standardized, streamlined ordering procedures.

GSA OASIS+ Phase II builds on the original eight domains by expanding the program to 13 total domains—adding five new domains: Business Administration, Financial Services, Human Capital, Marketing & Public Relations, and Social Services. GSA has stated the program will be continuously open and plans to re-open solicitations for submissions on or about January 12, 2026. In its most recent Phase II update (Pre-Amendment #8 notice), GSA also released draft scorecards for the domains and signaled forthcoming contract modifications for already-awarded contractors as part of the transition to Phase II.

OASIS+ Enrollment & Awards

According to GSA, OASIS Plus (OASIS+) will be an open enrollment opportunity, with the intention of enrolling more contractors. GSA intends to award separate IDIQ contracts under each of the following categories:

  • 8(a) small business
  • HUBZone small business
  • Service-disabled veteran-owned small business
  • Total small business
  • Women-owned small business
  • Unrestricted

Qualification standards for each IDIQ will be designed to achieve targeted socioeconomic representation. Unrestricted solicitations may require a higher qualifying threshold and additional qualifying criteria, such as: past performance exceeding subcontracting goals, greenhouse gas (GHG) emissions disclosures, experience performing IAW applicable labor laws (e.g., Service Contract Labor Standards, Collective Bargaining Agreements), experience with and/or plan to support other priorities (e.g., AbilityOne and minority-owned SBs).

Proposal Preparation

GSA OASIS Plus (OASIS+) is a Self-Scoring solicitation, meaning bidders score themselves on one or more factors according to the evaluation criteria (or evaluation matrix) and provide documentation to support their assertions. To succeed in this endeavored:

  1. a bidder must understand the qualification requirements and evaluation criteria
  2. recognize its qualifications that best match the requirements and achieve the highest score
  3. gather and provide documentation and evidence to substantiate those qualifications

Compared to other solicitations, in self-scoring solicitations each bidder must do the work of both a bidder and a contracting officer at the same time.
