How to Use OASIS
GSA’s 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.

Email links to Contractor pools are in the table below.
Please send all COCM and COPM updates, request for changes, or errors found in the spreadsheet to oasismods@gsa.gov (do not cc OASIS@gsa.gov or OASISsb@gsa.gov)
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 SB 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 (RFPs), Requests for Information (RFIs), or other Market Research requests to the OASIS U, OASIS SB, or OASIS 8(a) Prime Contract holders by Pool.
Important: Each Pool is a separate Multiple Award Task Order Contract (MATOC). When issuing an RFP, only one Contract Vehicle (OASIS U, OASIS SB, or SB 8(a) Subpools) and one Pool can be solicited. Pool selection is based on the predominate NAICS Code (definitions by OASIS Pool Numbers) [PDF - 177 KB] assigned to the solicitation (see Ordering Guide Appendix A [DOCX - 384 KB])
Select the OASIS Unrestricted pool link that corresponds to the predominate 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

GSA offers an optional OASIS scope review that analyzes the scope and Pool assignment of your proposed requirement.
To request a scope review you must:
- Complete the OASIS Scope Review Request Form(OSRRF) [DOCX - 62 KB]. Save and rename the file using the Project Name
- Use the OASIS NAICS Code definitions document to choose the NAICS code representing the principle purpose of your requirement
- Input that NAICS code and corresponding pool in the Primary NAICS field of the OSRRF. Example for military engineering: “NAICS 541330 Exception A (Pool 3)”
- Complete your Statement of Work (SOW)
- Complete your Independent Government Cost Estimate (IGCE) using your Agency’s government estimate with labor categories and hours template or generated using the OASIS Price Estimating Tool
- Email the completed OSRRF, SOW and IGCE to OasisScopeReviews@gsa.gov. Use the same project name used in the completed OSRRF for the email subject line
We cannot complete the scope review until the completed OSRRF, SOW and IGCE have been received. Note: If you do not hear back within five business days of submitting all documents, email OasisScopeReviews@gsa.gov for update.
Contract Features
The OASIS program has created a variety of crosswalks to guide buyers through the acquisition process.
Download this snapshot of the OASIS pools [PDF - 220 KB].
- 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'
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 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, OASIS Small Business Contracts, and OASIS Small Business 8(a) Subpool Contracts:

Research Tools
These tools are designed to help buyers make better program and business decisions.
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.

Discovery is a market research tool for GSA contracts including OASIS and OASIS Small Business (SB). Discovery streamlines the process for developing scenarios for set-asides on various contract vehicles to reduce, replace or support Requests for Information (RFI), saving time and cost for the federal government and contractors.
Discovery allows federal users to:
- Generate a listing of awarded contractors based on a primary North American Industry Classification;
- System (NAICS) code and filter for fair opportunity from a list of socioeconomic classifications;
- Find contractor administrative information such as points of contact, as well as, lists of current and completed contract actions from the Federal Procurement Data System (FPDS); and
- Download contractor details as a Comma Separated Values (CSV) file for offline use and analysis.
How Discovery Works
Discovery pulls information from FPDS to provide context-rich contract history on awarded contractors based on primary NAICS codes. Each contract is separated into Unrestricted and SB to make it easy to reserve task orders for small business categories.
With Discovery, users can research contracts by first selecting the contract vehicle of interest and then selecting a NAICS code/description matching the requirement. This will display all of the awarded contractors in that contract pool. A pool is a separate contract with one or more NAICS assigned and a single small business size standard. Each pool has unique qualifications tied to a specific scope identified by an assigned NAICS code.
On the vendor results page, users select a primary NAICS Code to view the vendor contract history, as well as up to date System for Award Management (SAM) registration data. Discovery also loads data from the FPDS to automatically provide you with a context-rich contract history for each contractor, including the amount of the contract, the primary NAICS code and the pricing type.

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).
The OASIS Price Estimating Tool User Guide [PDF - 1 MB], in combination with the OASIS Labor Categories Crosswalk [XLSX - 81 KB] companion document, provides detailed step-by-step instructions. For best results, the user must be familiar with the OASIS and OASIS Small Business contracts through self-study or by attending the Delegation of Procurement Authority (DPA) training. It is especially important to have an understanding of the Standardized Labor Categories and how they are priced.
Users can access the OASIS Price Estimating Tool directly (no log in or registration required) or via the GSA ASSIST web portal. Note: if accessing via ASSIST you must be registered in ASSIST.
