AI Contract Overview
The General Services Administration’s Federal Acquisition Service is managing the continuously open, multiple-award Indefinite-Delivery, Indefinite-Quantity (IDIQ) contract known as One Acquisition Solution for Integrated Services Plus (OASIS+), specifically under the Total Small Business Set-Aside solicitation 47QRCA23R0001-P2, with a North American Industry Classification System (NAICS) code of 541990. This contract facilitates the acquisition of professional services across twelve primary domains including Management and Advisory, Technical and Engineering, Research and Development, Intelligence Services, Environmental, Facilities, Logistics, Business Administration, Marketing and Public Relations, Human Capital, Financial Services, and Social Services. The contract has a five-year base period with a possible five-year option, extending the total term to ten years. All proposals must be submitted exclusively through the OASIS+ Symphony Portal (OSP) at oasis.app.cloud.gov, and offerors must maintain active and current registration in SAM.gov. Participation is limited to small businesses, and both the offeror and all proposed subcontractors must be registered with a unique entity identifier (UEID) and self-certify as small businesses under applicable size standards; any change in size status post-award must be immediately reported. Amendments to the solicitation, such as Amendment 0009 issued on July 7, 2026, require acknowledgments via signed SF30 forms, which must be uploaded correctly in Symphony for any pending offers submitted prior to the amendment. The solicitation permits submission of a single proposal across multiple domains with no fixed award timeline, as awards are made on a rolling basis to qualified offerors with fair and reasonable pricing. Evaluation is based on pass/fail gates—acceptability review, cost/price compliance, and responsibility determination—with technical qualifications assessed against objective thresholds in Attachment J.P-1, including qualifying project experience, federal prime contractor history, and past performance ratings. The contract includes standardized labor categories aligned with Bureau of Labor Statistics classifications and fully burdened ceiling rates for time-and-materials labor, with automatic 4.41% annual escalation for years one through fifteen. Contractors must comply with robust reporting obligations: transactional data including task order awards, modifications, invoices, and subcontracting amounts must be submitted via government-designated systems; additionally, a Contract Access Fee (CAF) calculated as a percentage of total invoice amounts—including labor, materials, overhead, and profit—must be included on each invoice and remitted to G
