OASIS Contracts

OASIS Unrestricted is a Full and Open contract whereas OASIS Small Business is a 100 percent Small Business Set-Aside contract (FAR 19.502) with the ability to do Socio-Economic Set-Asides (FAR 19.8 thru FAR 19.15) at the task order level.

Both OASIS Unrestricted and OASIS Small Business are a family of 7 separate Governmentwide Multiple Award, Indefinite Delivery, Indefinite Quantity (MA-IDIQ) task order contracts that span 28 North American Industry Classification System (NAICS) Codes and 6 NAICS Code Exceptions under the economic subsector 541 - Professional, Scientific, and Technical Services.

Below are copies of the OASIS Unrestricted (current as of November 29, 2018) and OASIS Small Business Contracts (current as of September 24, 2018).

Please Note:

  • Each of the seven separate MA-IDIQ task order contracts (MATOCS) are individually referred to as “Pools” within the OASIS Unrestricted, OASIS Small Business, and OASIS SB 8(a) Contracts. Each Pool is a separate MATOC.
  • When issuing a Request for Proposal (RFP) under OASIS, only one contract vehicle (OASIS Unrestricted, OASIS Small Business, or OASIS SB 8(a)) and only one Pool can be solicited. Pool selection is based on the predominate NAICS Code assigned to the task order solicitation (See Section H.4. of each MATOC for NAICS Code Pool selection).
