The key products and services being delivered under this federal contract IDV award are comprehensive professional services across seven functional domains: Management and Advisory, Technical and Engineering, Research and Development, Intelligence Services, Environmental Services, Facilities, and Logistics. The contract vehicle, known as OASIS+ (One Acquisition Solution for Integrated Services Plus), is a multiple-award Indefinite Delivery Indefinite Quantity (IDIQ) contract awarded by the General Services Administration's Federal Acquisition Service. The contract has a total small business set-aside, with a ceiling value of nearly $1 trillion and a performance period through September 2029. The prime contractor, Software Engineering Services Corp (SES), is a minority-owned small business providing IT consulting services and solutions to the federal government, with a focus on complex professional services such as program management, engineering, logistics, and scientific support. SES has been awarded several significant task orders under the OASIS SB IDIQ contract, primarily from the Department of the Air Force, and also holds two additional OASIS SB contracts that allow federal agencies to directly order total small business set-aside task orders. The original solicitation (47QRCA23R0001) sought to establish a government-wide IDIQ contract vehicle that allows federal agencies to procure integrated solutions for complex service requirements across multiple NAICS codes within each functional domain. Offerors were evaluated based on their qualifying project experience, federal prime contractor experience, business systems and certifications, past performance, and cost/price proposals. The contract includes a 5-year base period with one 5-year option period, and successful offerors include a range of small businesses that can compete for task orders in any domain/NAICS code where they qualify as small businesses.
