The GSA OASIS Tier 3, Best-in-Class (BIC) solutions make procuring complex professional services expedient by maximizing streamlined acquisition processes. The following resources are designed to help buyers use the OASIS suite of contracts.
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.
Warning: It is strictly prohibited to send emails by way of the following Pool Links if you are not an authorized government official. Non-authorized personnel may contact the Prime Contract holders individually but not through the use of the following Pool Links.
The following OASIS Unrestricted (U), OASIS Small Business (SB), and OASIS 8(a) Pool Links generate a group email to the official Points of Contact for all the Prime Contract holders in the respective Pools
The primary purpose of the Pool links are for authorized government officials issuing Requests for Proposals (RFP), Requests for Information (RFIs), or other Market Research requests to the OASIS U, OASIS SB, or OASIS 8(a) Prime Contract holders by Pool.
A document used in negotiated procurements to communicate government requirements to prospective contractors (firms holding schedule contracts) and to solicit proposals (offers) from them.
Select the OASIS Unrestricted pool link that corresponds to the predominate North American Industry Classification System (NAICS) code when issuing a RFP that is not a Total Small Business Set- Aside. Select the OASIS SB pool link that corresponds to the predominate NAICS code when issuing a RFP that is a Total Small Business Set-Aside (FAR 19.502-2).
Note: If clicking on the email link does not automatically pull up your email drafts, copy and paste the link into your email. Please do NOT carbon copy (cc) the OASIS@gsa.gov or OASISSB@gsa.gov in your email to OASIS contractors

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.

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'

The OASIS Labor Category Crosswalk Table [XLSX - 81 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.

The OASIS Program created a tool that takes its data to the next level. OASIS stakeholders can now view and segment OASIS information to make better program and business decisions.
With the OASIS Dashboard, you have the ability to:
Explore OASIS and OASIS SB data by federal agency and industry partner; and
Build customized reports and download them to your computer.
Notice to Users: GSA strives to comply with Section 508 of the Rehabilitation Act of 1973. Some of the dashboard content presented through .swf files may not be completely accessible to users of assisted technology. If you experience technical issues, please contact BIEDW Support.
The Contract-Awarded Labor Category (CALC) tool helps federal contracting officers and others find awarded prices to use in negotiations for labor contracts. It offers ceiling prices, fully burdened costs, services data, and worldwide rates.
The OASIS Price Estimating Tool is designed to assist you in preparing the labor portion of your Independent Government Cost Estimate (IGCE).
Traveler reimbursement is based on the location of the work activities and not the accommodations, unless lodging is not available at the work activity, then the agency may authorize the rate where lodging is obtained.
Unless otherwise specified, the per diem locality is defined as "all locations within, or entirely surrounded by, the corporate limits of the key city, including independent entities located within those boundaries."
Per diem localities with county definitions shall include"all locations within, or entirely surrounded by, the corporate limits of the key city as well as the boundaries of the listed counties, including independent entities located within the boundaries of the key city and the listed counties (unless otherwise listed separately)."
When a military installation or Government - related facility(whether or not specifically named) is located partially within more than one city or county boundary, the applicable per diem rate for the entire installation or facility is the higher of the rates which apply to the cities and / or counties, even though part(s) of such activities may be located outside the defined per diem locality.
