Ruby V Marcelo

Ruby V. Marcelo serves as a key procurement lead at the U.S. Embassy in Geneva, supporting the Department of State’s mission to maintain secure, compliant, and operationally ready diplomatic infrastructure. She manages a portfolio of facility support contracts critical to embassy functionality, including building systems, environmental controls, and mission-critical maintenance services. Her work ensures that physical infrastructure meets international safety standards and U.S. government operational requirements, with a focus on lifecycle management of mechanical, electrical, and civil support systems. Marcelo routinely handles complex, multi-year service acquisitions under FAR Part 37 and FAR Part 16, emphasizing performance-based contracting and integrated facility services. Her contractor relationships center on specialized service providers in building systems and environmental maintenance, with consistent engagement with plumbing, heating, air-conditioning, and building equipment contractors. She cultivates long-term partnerships with vendors possessing technical expertise in elevator systems, HVAC retrofits, and facility automation, prioritizing vendors with proven experience in diplomatic and high-security environments. Marcelo’s procurement approach emphasizes reliability, regulatory compliance, and continuity of service, often requiring contractors to meet stringent U.S. diplomatic security and environmental standards. Marcelo’s contracting patterns reflect a strong preference for open competition, with 92.3% of awards issued without set-aside restrictions. The remaining 7.7% are allocated under the Local Area Set-Aside authority (FAR 26.2), demonstrating targeted support for Swiss-based businesses with demonstrated capacity to deliver mission-critical services within diplomatic compound constraints. While she does not routinely utilize 8(a), HUBZone, or SDVOSB set-asides, her approach ensures fair and reasonable competition while aligning with State Department’s global procurement directives. Her primary procurement focus lies in NAICS 238220 (plumbing, heating, and air-conditioning), NAICS 561730 (landscaping services), NAICS 333921 (elevator manufacturing), and NAICS 238290 (other building equipment contractors).
