One Acquisition Solution for Integrated Services (OASIS+) Multi-Agency Contract (MAC) Indefinite-Delivery Indefinite-Quantity (IDIQ) Service Disabled-Veteran Owned Small Business Phase II

OASIS+ is a governmentwide multiple award indefinite delivery indefinite quantity contract managed by the General Services Administration's Federal Acquisition Service. Designed for federal agencies to procure non-IT services, the contract is organized into specific domains that group related services and industry codes. Initial domains include Management and Advisory, Technical and Engineering, Research and Development, Intelligence Services, Environmental, Facilities, and Logistics, with an additional Enterprise Solutions domain reserved for unrestricted solicitations. The Phase II reopening expands these capabilities to include Business Administration, Financial Services, Human Capital, Marketing and Public Relations, and Social Services. This specific contract vehicle is a Service-Disabled Veteran-Owned Small Business set-aside, providing targeted opportunities for SDVOSB entities. A key feature of the program is its continuous on-ramping process, which allows new contractors to submit proposals and enables existing contract holders to expand their scope by adding new domains. This structure ensures a flexible and evolving procurement mechanism that can adapt to the changing service needs of various federal agencies.
