About the company
Fellenzer Engineering LLP, a Service-Disabled Veteran-Owned Small Business (SDVOSB) and SBA-certified Veteran-Owned Small Business (VOSB) based in Middletown, New York, delivers architectural and engineering design services to the Department of Veterans Affairs and the Department of the Army as a prime contractor exclusively, with no subcontract footprint across its 196 federal awards. The firm operates as a limited liability partnership under NAICS 541330 (Engineering Services) and PSC codes anchored in Architect and Engineering–Construction (hospitals and infirmaries) and Architect and Engineering–General (landscaping, interior layout, and design), and competes predominantly under SDVOSB and VOSB set-asides, though non-set-aside awards and sole-source justifications recur when Fellenzer holds prior design liability or base-building knowledge.
Fellenzer's customer base is heavily concentrated with the Department of Veterans Affairs Veterans Health Administration Veterans Integrated Service Network 2 (VISN 2), which accounts for 103 awards and $26.9 million of the firm's $47.3 million combined potential value across all awards—a 79% share of award count and 57% of dollar value. The Department of the Army Installation Management Command Northeast Region anchors the second-largest customer by potential value, with five awards worth $8.8 million, while VISN 1 and other VA components round out active volume. All customer concentration sits within a 300-mile radius of the firm's northeastern headquarters, with work performed at VA medical centers in Albany, Stratton, Bronx, West Haven, Newington, and Montrose, New York; Bedford, Massachusetts; and the United States Military Academy at West Point.
Fellenzer's work portfolio spans clinical facility design, infrastructure renovation, and specialized mechanical and electrical systems. Representative prime work includes a $928,430 firm fixed-price definitive contract from VISN 2 (awarded January 2024) for architectural and engineering drawings and design for an emergency service building with ultimate completion in January 2029; a $698,837 contract (February 2025) for HVAC replacement in operating rooms, medical intensive care unit, and kitchen spaces with May 2030 completion; a $731,843 delivery order (September 2024) from the Army Northeast Region under a $6.5 million total small business IDC for engineering and architectural design of walk-in coolers and freezers at West Point's Cadet Mess Hall; and a $992,653 delivery order (June 2023) from the Army for cadet uniform facility services at West Point through July 2026. Fellenzer also serves as the primary architectural and engineering firm for multiple VISN 2 projects including facade design phases, respiratory therapy renovation, endoscopy expansion, and specialty systems such as fire alarm replacement, public address and mass notification system upgrades, and building management system network design.
The firm places task orders under five parent Indefinite Delivery Contracts—V10N3P2755 (26 task orders, $3 million combined potential value), VA243P0230 (24 task orders, $2.6 million), VA52812D0100 (11 task orders, $856 thousand), V10N3P2124 (8 task orders), and V10N3P0047 (7 task orders)—all VA-sourced single-award vehicles that anchor Fellenzer's recurring work stream with VISN 2. Activity has declined sharply in recent years: eight awards in 2022, twelve in 2023, two in 2024, four in 2025, and two through February 2026. Within the next twenty-four months, eighteen awards carrying $6.6 million in combined potential value face ultimate completion dates, creating recompete exposure across multiple clinical and infrastructure renovation projects at VA medical centers and West Point facilities. The firm's data suggests depth in healthcare facility design and federal installation modernization spanning more than three decades of registered federal work, with demonstrated SDVOSB set-aside positioning and established relationships as the preferred A/E vendor for VISN 2 facility infrastructure modernization across its northeastern service area.
