One Acquisition Solution for Integrated Services +
One Acquisition Solution for Integrated Services Plus (OASIS+) is a suite of governmentwide, multi-award contracts designed to support federal agencies’ procurement requirements for services-based solutions. This suite of services contracts is available for use by agencies throughout the Federal Government who hold a Delegation of Procurement Authority (DPA).
OASIS+ is a collection of multiple-award, Indefinite Delivery, Indefinite Quantity (IDIQ) contracts, of which the contract base period is five (5) years with one (1) option period of five (5) years that may extend the cumulative contract ordering period to 10 years. Task orders can be awarded under OASIS+ any time prior to the expiration of the ordering period of the master contracts. Notwithstanding, the OASIS+ IDIQ master contracts (contractor specific) can have different award dates; however, all contracts for each specific MAC have the same contract end dates (e.g., all of the Small Business contracts will end on the same date).
OASIS+ contracts may be used by all federal agencies, including the Department of Defense (DoD) and Federally Funded Research and Development Centers (FFRDCs), but are not open to state and local governments at this time.
Orders issued against the OASIS+ contracts are considered Interagency Acquisitions. GSA has specific statutory authority under 40 U.S.C. 501 to purchase supplies and non-personal services on behalf of other agencies. Therefore, the Economy Act does not apply to OASIS+ orders.
Longeviti LLC Domains:
Facilities (FAC)
Services in this domain include any and all services required to maintain and operate buildings, paved services, utilities infrastructure, and real property assets and equipment. This could include major facilities support such as Department of Defense installations, hospitals, cemeteries, and other federal or industrial real property, but does not include major or primary purpose construction. GSA has included a wide range of services found in facilities contracts because of their historical use to support total facilities solutions.
Logistics (LOG)
Services on this domain include comprehensive logistics solutions, including planning and designing, implementing, or operating systems or facilities for the movement of supplies, equipment, or people by road, air, water, rail, or pipeline.

The SeaPort Next Generation (SeaPort NxG) multiple award contracts (MACs) were awarded in December.
SeaPort NxG supports: Naval Sea Systems Command; Space and Naval Warfare Systems Command; Naval Supply Systems Command; Military Sealift Command; Naval Facilities Command; Office of Naval Research; and U.S. Marine Corps.
Services provided under SeaPort NxG are categorized into two major categories, which may be performed for new and existing product areas, programs, or missions assigned to these activities during the life of the contract.
Engineering Services consist of the application of engineering disciplines to technically support the research and development (R&D) of new and existing Naval capabilities and systems, technically support development of significant alterations to existing systems, support integration and interface of existing equipment or software into different applications or platforms to support the warfighter, and support evaluation of foreign or non-developmental systems, equipment, and technologies. This category also includes all support required within the area of environmental engineering of U.S. Navy weapon systems and base-related infrastructure. Functional areas under this category include, but are not limited to, the following:
Engineering, System Engineering, & Safety & Process Engineering Support
In-Service Engineering, Fleet Introduction, Installation & Checkout & Provisioning Support
Reliability, Maintainability, & Availability (RM&A) Support
System Design Documentation & Technical Data Support
Software Engineering, Development, Programming, & Network Support
Modeling, Simulation, Stimulation, & Analysis Support
Prototyping, Pre-Production, Model-Making, & Fabrication Support
Measurement Facilities, Range, & Instrumentation Support
Interoperability, Test & Evaluation, Trials Support
Inactivation & Disposal Support
Program Management Services consist of applying the business, financial management, and technical disciplines required to support planning, organizing, staffing, controlling, and leading team efforts in managing acquisition programs such that the result places a capable and supportable system in the hands of the warfighter, when and where it is needed, and does so at an affordable price. This category represents an integration of a complex system of differing but related functional disciplines that must work together to achieve program goals through development, production, deployment, operations, support, and disposal. Functional areas under the Program Management Services category include, but are not limited to, the following:
Functional & Direct Programmatic Administrative Support
Analytical & Organizational Assessment Support
Financial Analysis & Budget Support
Logistics Support
Configuration Management (CM) Support
Quality Assurance (QA) Support
Professional Development & Training Support
Computer Systems Analysis
Information System (IS), Assurance (IA), & Technology (IT) Support

Electronic Federal Aviation Administration Accelerated and Simplified Tasks (eFAST)
eFAST is a set-aside for small businesses, Socially and Economically Disadvantaged Businesses (SEDB) 8(a), Service Disabled Veteran Owned Small Businesses (SDVOSB), Women Owned Small Businesses (WOSB), Economically Disadvantaged Women-Owned Small Businesses (EDWOSB), Historically Underutilized Business Zone (HUBZone) Small businesses, and 8(a) Indian Tribal Owned and Alaska Native Corporations (ANC). Other set-asides will be employed as set forth in the FAA’s Acquisition Management System (AMS).
eFAST is the FAA’s preferred contracting vehicle for procuring small business services. The program provides a streamlined acquisition process for technical, professional, and administrative support through Master Ordering Agreements (MOAs) that function as Blanket Purchase Agreements (BPAs).
eFAST accommodates multiple contract types, including firm-fixed-price, cost-reimbursement, time-and-materials, and labor-hour arrangements. This flexibility allows the FAA to structure individual requirements around its operational, technical, and business needs.
Longeviti LLC holds an eFAST Master Ordering Agreement covering all eight functional areas, providing an acquisition pathway for services supporting FAA programs and missions.
