Dual OASIS+ awards expand IMJV's ability to provide high-quality, comprehensive management, advisory, engineering, and technical services to federal agencies

STERLING AND FALLS CHURCH, VA, UNITED STATES, May 7, 2025 /EINPresswire.com/ -- ISI-Markon JV LLC (IMJV), a national leader in critical infrastructure and business operations for the nation’s federal civilian, defense, and intelligence agencies, is proud to announce its award of the General Services Administration (GSA) One Acquisition Solution for Integrated Services Plus (OASIS+) Indefinite Delivery, Indefinite Quantity (IDIQ) Small Business (SB) and Service-Disabled Veteran-Owned Small Business (SDVOSB) contracts, a 10-year opportunity to deliver innovative solutions to government customers. This milestone expands IMJV’s ability to support federal agencies with high-quality, comprehensive management, advisory, engineering, and technical services.

IMJV is a Joint Venture (JV) established under the U.S. Small Business Administration’s All Small Mentor-Protégé Program (ASMPP). The JV is powered by a decade-long strategic partnership between ISI Professional Services (ISI)—an SDVOSB and managing member—and Markon, LLC, the mentor firm and JV member. Together, the firms bring more than 90 years of combined federal prime contractor experience and a proven track record of driving performance and mission success.

“IMJV’s award of the GSA OASIS+ contract marks a significant milestone in our commitment to delivering agile, people-centric solutions that address the complex challenges facing our federal clients,” said ISI President and CEO Chris Lefebvre. “This achievement reflects the dedication and collaboration of our entire team and underscores our dedication to excellence and our unwavering focus on making a difference in every mission we undertake.”

The GSA OASIS+ contract, a “Best-in-Class” (BIC) government-wide acquisition contract (GWAC), provides federal agencies with streamlined access to a broad range of professional services. With a performance period until June 30, 2034, and an option period extending through 2034, these contracts enhance IMJV’s capacity to deliver innovative and mission-critical solutions across federal agencies.

Through OASIS+, IMJV is eligible to compete for and execute task orders across 22 Contract Line-Item Numbers (CLINs) in two key domains, Management and Advisory, and Technical and Engineering:

Markon CEO Raymond Carney stated: “At Markon, we believe in showing up every day with a clear focus—to support our clients’ missions with dedication, precision, and heart. This OASIS+ award reflects the trust placed in ISI-Markon JV by our federal partners—and, more importantly, the shared talent, values, and commitment of our teammates across both organizations.
