Review the OASIS and OASIS SB Master Contracts.
Through the use of OASIS SB, customer agencies receive small business credit, and it supports competition, even in socioeconomic categories.
- Agencies can plan socioeconomic set asides to meet their goals and support 8(a), HUBZone, and SDVOSB.
OASIS facilitates agency management of its SB program and goals through awards in every SB category, including socioeconomics and provides business intelligence on SB performance via dashboards.
- Agencies can reserve task orders for exclusive competition among SB categories, including:
- HUBZone SB concerns
- 8(a) business development participants
- Service-disabled veteran-owned small business (SDVOSB) concerns
- Economically disadvantaged women-owned small business (EDWOSB) concerns; and
- Women-owned small business (WOSB) concerns eligible under the Women-Owned SB Program.
Two ways to access OASIS:
- Direct Acquisition - GSA issues a Delegation of Procurement Authority to the customer agency Ordering Contracting Officer (OCO) who performs the acquisition; or
- Assisted Acquisition - GSA performs the acquisition on behalf of the customer agency and provides post-award support, as negotiated with the customer. An Inter-Agency Agreement is required.
Tiered Access Fee - OASIS offers an Innovative tiered access fee, ranging from 0.1 percent - 0.75 percent based on obligation level (see Agency Agreements links in the OASIS Reference Library).
OASIS has no program ceiling, a five-year base and one five-year option a benefit to long-term planning for complex program requirements.
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.'
The 28 NAICS codes [PDF - 75 KB] (and 6 exceptions) are allocated among seven 7 NAICS code pools.
- 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 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.
