FELLENZER ENGINEERING LLP

Fellenzer Engineering LLP specializes in comprehensive engineering and architectural services for federal facilities, with a strong focus on mission-critical infrastructure upgrades within Veterans Affairs campuses. The firm delivers full-cycle design and analysis for building systems including HVAC, hydronic networks, building management systems (BMS), roofing, underground storage tanks, and public address/mass notification infrastructure. Their technical expertise spans architectural documentation, mechanical system rehabilitation, structural integration, and code-compliant renovations, with particular proficiency in retrofitting aging VA medical facilities to meet modern safety, accessibility, and operational standards. A key differentiator is their ability to coordinate complex, multi-disciplinary design efforts—such as integrating BMS network upgrades with HVAC replacements—while maintaining continuous facility operations during construction. The contractor maintains a deep, sustained relationship with the Department of Veterans Affairs, consistently delivering engineering and architectural services across VA medical centers and outpatient clinics nationwide. Their work supports VA’s capital improvement goals, focusing on life safety, energy efficiency, and ADA compliance in high-traffic clinical and administrative buildings. While they have also supported the Department of Defense with facility modernization projects, the VA remains their primary and most trusted client, reflecting a proven track record in delivering mission-aligned solutions within a highly regulated healthcare environment. Fellenzer Engineering’s primary focus is on NAICS 541330 (Engineering Services) and 541310 (Architectural Services), positioning them as a niche provider of integrated design solutions for federal healthcare and defense infrastructure. They specialize in facility lifecycle management, from condition assessments and system analysis to schematic design and construction documentation, serving clients who require precision in renovating legacy structures without disrupting operations. As a Service-Disabled Veteran-Owned Business headquartered in Middletown, New York, Fellenzer Engineering leverages its certification to align with federal procurement priorities while maintaining a focused, agile delivery model tailored to the unique demands of federal facility modernization programs.
