Review the North American Industry Classification System (NAICS) Code Definitions by OASIS Pool Numbers [PDF - 177 KB]
The standard federal agencies use to classify business establishments for the purpose of collecting, analyzing, and publishing statistical data related to the U.S. business economy.
- All codes/exceptions in a pool share a common small business (SB) size standard.
- Agencies can solicit task order proposals from contractors holding awards in the pool with the NAICS code that matches the agency’s requirement.
The core disciplines/scopes of the contracts include:
- The labor categories are aligned with occupations, as outlined in the Office of Management and Budget’s (OMB) Standard Occupational Classification (SOC) system.
- OASIS offers more meaningful proposed rate comparisons at the Task Order level (apples to apples)
- 104 OASIS LCATs (individual and groups priced at the master contract level)
- 127 OMB SOC occupations, and
- 1,000 typical industry job titles
- The remaining 840 SOC occupations can be added and priced at the task order level as ‘ancillary labor’
A federal agency responsible for assisting the president in meeting policy, budget, management and regulatory objectives and to fulfill the agency’s statutory responsibilities.
The OASIS Labor Category Crosswalk Table [XLSX - 80 KB] compares Industry’s functional job descriptions and specific the Office of Management and Budget (OMB) Standard Occupational Classification (SOC) system occupational descriptions. In this table, you will find more than a thousand industry job titles with suggested SOC occupation and OASIS LCAT matches.
The OASIS Table of PSC codes by OASIS pool number [XLSX - 67 KB] is excerpted from Federal Procurement Data System-Next Generation (FPDS-NG) and only includes those in scope. Select the link to search for your Pool number and the various possible PSC Codes that may apply. (Note: The white drop down arrows on the table will streamline the process.)
Note: Ordering Contracting Officers (OCOs) are required to identify, in each task order solicitation, the PSC that represents the principal nature of the work, and report these PSCs in FPDS-NG.
The core disciplines/scopes of the contracts include:
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. The OASIS 8(a) SubPools were developed to provide the 8(a) community expanded access to the OASIS Best-in-Class contract program while creating more options for federal agencies to meet their 8(a) business development program goals through both competitive 8(a) set-asides and 8(a) directed task order awards.
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 NAICS Codes and 6 NAICS Code Exceptions under the economic subsector 541 - Professional, Scientific, and Technical Services.
OASIS contract end dates:
- Unrestricted: March 1, 2025 (Note: extended on August 25, 2023, in accordance with FAR 52.217-8 Option to Extend Services (NOV1999) as permitted by the contract at Section I.4.6.)
- Small Business: December 19, 2024
- 8(a): December 19, 2024
In accordance with FAR 52.216-22, Indefinite Quantity, paragraph (d), any task order issued during the active period of performance of the master contracts may proceed up to five years following the expiration of the contract ordering period. (Eg., a task order issued on the last day of the IDIQ’s active period of performance may be issued for a base and four option periods, and all option periods can be exercised per the Ordering Contracting Officer’s (OCO) determination).
The OASIS contracts have different start dates, due to onramps that followed the initial awards; therefore, we aren’t publishing the start date of the contracts. If you need to know a specific contract’s start date, please contact the OASIS Program Office at oasis@gsa.gov.
