GSA’s OASIS+ : Latest Updates

Sep 20, 2023

The General Services Administration (GSA) recently issued a draft Statement of Work for its Best-in-Class Multiple Award Contract (BIC MAC) – the upcoming successor to its One Acquisition Solution for Integrated Services (OASIS) Contract. OASIS has been one of GSA’s most successful vehicles, accounting for $35 billion in obligations, and BIC MAC (now OASIS+) is all set to take its place in the coming years. GSA, on 15th June 2023, released the final Request for Proposal (RFP) for the OASIS+ Program.

GSA OASIS+: What is the Recent Update About?

April 22, 2024

On April 22, 2024, GSA’s Office of Professional Services and Human Capital Categories (PSHC) will issue a post closing solicitation amendment to incorporate the requirements of Federal Acquisition Regulation (FAR) Case 2020-11, as prescribed in FAR 4.2306(c), and to incorporate solicitation changes to update additional information in all six OASIS+ solicitations. The Amendment is number 0006.

The following are the specific updates that will be made to the solicitations: 
  • The provision at FAR 52.204-29, Federal Acquisition Supply Chain Security Act Orders—Representation and Disclosures, is being incorporated into the solicitation.
  • The clause at FAR 52.204-30 – Alternate 1, Federal Acquisition Supply Chain Security Act Orders – Prohibition, is incorporated by full text into the solicitation (and subsequent awarded contracts).
  • A revision is being made to correct an erroneous small business size standard corresponding to one North American Industry Classification System (NAICS) code in the Environmental Domain.
  • Updates are being made to Section F and G administrative requirements to comply with FAR Clause 52.204-30 – Alternate 1, para (c)(3)(i).

The Office of Professional Services and Human Capital (PSHC) released the eighth in a series of program updates to OASIS+ to keep the industry informed. This update includes the remaining draft Qualifications Matrices for the initial phase of the procurement. The following domains are now included in the Qualifications Matrix document:

  • Facilities (Unrestricted)
  • Intelligence (Small Business and Unrestricted)
  • Logistics (Small Business and Unrestricted)
  • Research and Development (Small Business and Unrestricted)

Each matrix includes specific evaluation criteria and relative evaluation credit to qualify for specific Domains on OASIS+. Additionally, the government is providing a new provisional attachment that includes a list of NAICS and PSC codes under consideration to demonstrate project relevance (Criteria 1 – QP-Relevance), provided the code is selected specifically for that project. Furthermore, this attachment will also be used to demonstrate the breadth of experience. Instructions are included in this attachment.

More details regarding the above highlights can be found in the documents on the OASIS+ Interact page.

GSA has noted that it will continue to update this posting with the latest OASIS+ developments. It still intends to release a Draft RFP for total Small Business and Unrestricted in the Fall of 2022.

August 13, 2022

GSA released the 7th update on the OASIS+, in which the draft of section B, section G, and section H was released. These sections include a proposed strategy for on-ramping/off-ramping, among other important highlights related to transactional data reporting and other contract requirements.

GSA has also released an updated draft Qualifications Matrix document in which qualifying criteria for the Environmental and Facilities Domains have been included. Each matrix includes specific evaluation criteria and relative evaluation credit to qualify for a Domain. Additionally, each Domain’s tab includes a list of NAICS and PSC codes under consideration to demonstrate project relevance (Criteria 1 – QP-Relevance), provided the code is selected specifically for that project.

GSA is also anticipating more updates related to remaining Domain qualifications next month culminating in a complete draft RFP in the first quarter of FY2023. In case the offerors have to provide feedback or have any questions related to this program update, then can send them through an email to

July 15, 2022:

The update stated that there would be six domains, and each domain would have a different qualification method based on the draft domain qualification matrix. This matrix provides specific evaluation criteria for each domain and lists the NAICS and PSC Codes that offerors can leverage in a domain. The domains are as follows:

  • Technical & Engineering – Small Business
  • Technical & Engineering – Unrestricted
  • Management & Advisory – Small Business
  • Management & Advisory – Unrestricted
  • Enterprise Solutions – Unrestricted

These were the other main updates released:

  • Q&A responses for Section L&M were released
  • The minimum annual value threshold for Qualifying Project increased from $250K to $500K for the Tech & Engineering and Management & Advisory Small Business Domains.
  • Solicitation qualification criteria related to Retention and Emerging Technologies were eliminated. Instead, GSA will consider collecting this information from awardees for task order market research purposes.
  • Utilizing a 10-year ordering period without options.
    • All contracts awarded under OASIS+, including those awarded in later phases or through an open season, will have the same end date.
    • As in the legacy OASIS contracts, task orders can extend five years beyond the ten-year ordering period.
    • Absent the typical five-year option, small businesses will still be required to represent their size status before the end of the fifth year in accordance with FAR 52.219-28(b)(3)(i).

June 22, 2022:

A new oasis is on the horizon. OASIS’s successor GSA BIC MAC (GSA’s New Professional Services IDIQ) that has been in the making for over a year now, has now been named OASIS Plus (OASIS+). GSA announced yesterday that it intends to release the Draft RFP in Fall of 2022. Further updates will be posted on and interested parties are encouraged to keep an eye on this new Interact page for updates. Now is a good time to review this upcoming opportunity, and consider adding it to your business’s proposal pipeline.

Earlier Updates

OASIS+ will be organized by Domains – which are functional groupings of services, representing a common scope, spanning multiple NAICS codes. The purpose of these Domains is to align order requirements to industry partners that are qualified to perform the services covered under them. Right now, GSA anticipates awarding Domains in phases. We have presented an overview of each Domain with some examples below. These examples are not completely exhaustive but general indications of the types of services to be performed.

Management and Advisory: This Domain encompasses a broad range of management and consulting services to help federal agencies enhance their performance, accomplish mission objectives, and provide operational guidance and support on administrative and management challenges. Some of the examples of this Domain include but are not limited to acquisition and grants management support, business case development/analysis support, change management, configuration management, information analytics, leadership, and organizational assessments and risk assessment, mitigation, and management.

Technical and Engineering: This Domain includes requirements for providing specialized engineering, geoscience, or other technical professional skills performed by engineers, geologists, geophysicists, and technicians to optimize operating conditions and problems to assist the government. This Domain generally encompasses the application of physical laws and principles of engineering in the design, development, and utilization of machines, materials, instruments, processes, and systems; and providing expert advice and assistance on technical functions and issues.

Research and Development (R&D): The Research and Development (R&D) domain is concerned with achieving any specific or general R&D goals for basic research, applied search, and experimental development. The services for the R&D include the physical, engineering, and life sciences; nanotechnology; biotechnology; and social sciences and humanities. Examples include but are not limited to R&D of automated processes or robotics, psychological science research, life science research, mathematical science research, physical science research, biotechnology research, and process development.

Intelligence Services: This Domain covers technological capabilities to enhance Command, Control, Communications, Intelligence, Surveillance, and Reconnaissance mission requirements for the defense and intelligence ecosystem. This service will encompass command and control strategies for intelligence advantage, highlighting a number of initiatives unique to their specific primary missions and in support of solutions for Command, Power and Integration support, Cyber and Tactical Network science, Information Superiority Support, Intelligence Information, Electronic Warfare, Network Visualization, Signals Intelligence, Software Development for specific IT Services, and many more.

Enterprise Solutions: This Domain comprises non-IT services that assist national security systems in accordance with 40 USC § 11103 (a). It contains specialized and highly technical mission objectives that require special management attention due to their importance to the agency’s mission, high development, operating, or maintenance costs, high risk, or high return, or their significant role in the administration of agency programs, finances, property, or other resources.

Environmental Services: This Domain is concerned with faster, more cost-effective ways for agencies to meet environmental objectives. Requirements generally involve diverse teams of scientists, engineers, and other technicians with expertise in areas such as air and water quality, climate change, asbestos contamination, remediation, ecological restoration, and environmental law such as Planning and Documentation Services for the development, planning, facilitation, coordination, and documentation of and/or for environmental initiatives or mandates in chemical, radiological, and/or hazardous materials. Examples include but are not limited to air monitoring, air toxicology, criteria pollutants and Greenhouse Gas (GHG) emissions strategy and analyses, Carbon capture, utilization and storage, Geographical information systems (GIS) support, among others.

Facilities: Evident from the name, this Domain encompasses utility infrastructure, paved services, building maintenance, and real property assets and equipment. The scope for this Domain could include support for federal or industrial real property such as Department of Defense (DOD) installations, hospitals, cemeteries, etc. However, it does not include major/primary purpose construction. Examples include but are not limited to Civil engineering services, Commissioning services, Communication services – general, Building inspection services (including OSHA), Building management services, Cathodic protection, and corrosion control, etc.

Logistics: This Domain focuses on planning and designing, implementing, or operating systems or facilities providing the required distribution and movement of products, ensuring that goods are delivered successfully by road, air, water, rail, or pipeline. This requirement includes reliable strategies for Specialized Cargo Management, Rapid Deployment Of Supplies and Equipment Through Communication and Logistics Systems, ILS Risk Assessment, Schedules Creation and Performance Tracking, Food and Perishable Goods Supply Services, and many others.

Two of the domains included in the recent update, Enterprise Solutions and Logistics, were not among the initial concepts but have been included in the recent update.

What Services Have Been Excluded from the Scope of OASIS+?

According to the recent update, the following services are excluded from the scope of OASIS+:

  • Requirements that come under Inherently Governmental Functions defined in FAR Subpart 2.101
  • Requirements for Personal Services as laid down in FAR Subpart 2.101
  • Any requirement whose main purpose comes under the scope of FAR part 36
  • Any requirement whose principal purpose is in a NAICS code not listed under the corresponding Domain solicited

How will GSA prioritize and sequence Domains?

Based on data-driven assessments of need, the GSA will prioritize and add additional Domains (e.g., gaps in existing BIC solutions, anticipated demand changes, emerging administration directives). Future Domains will be unveiled in close collaboration with stakeholders and market research to back them up. GSA is taking the following criteria into account for prioritizing and sequencing Domains for the new Services MAC:

  • The administration will make judgments concerning these Domains based on their priorities
  • According to market research, demand for complex services is expected to increase over time, which will inform prioritization
  • The ordering period for OASIS will end in 2024. OASIS+ will expand on OASIS’s capabilities while also addressing customer requests that were not fulfilled satisfactorily by the previous contract
  • Historic spending on services makes it necessary to execute a Domain release prioritization plan that reflects anticipated spend based on market research
  • The availability of existing Best-in-Class IDIQs, such as HCaTS, which recently exercised its option, eliminates the need to duplicate services provided early in the life cycles of new services contracts

The Way Forward

GSA’s Office of Professional Services and Human Capital Categories (PSHC) will be releasing further program updates and other sections of the draft RFP in the coming months, ensuring that the industry has enough time to provide feedback before the complete draft solicitation is released (possibly in the next calendar year). GSA is currently accepting questions and feedback from the industry related to this update.
