Sara Dyer

Sara Dyer serves as the primary procurement lead for the U.S. Embassy in Lima, operating under the Department of State’s Office of Overseas Buildings Operations. In this role, she manages the acquisition of critical infrastructure support services essential to mission continuity, with a specialized focus on climate control and environmental systems for diplomatic facilities. Her responsibilities include soliciting, evaluating, and awarding contracts for air-conditioning, heating, and industrial refrigeration equipment, ensuring compliance with U.S. government standards for security, durability, and energy efficiency in high-risk overseas environments. She plays a central role in sustaining operational readiness by securing mission-critical environmental systems that protect personnel, sensitive equipment, and diplomatic assets across Peru’s diverse climatic zones. Sara Dyer collaborates with a broad network of qualified vendors specializing in commercial and industrial HVAC and refrigeration systems, including domestic manufacturers, international distributors, and systems integrators with proven experience in embassy-scale installations. Her contracting approach emphasizes technical compliance, lifecycle cost analysis, and post-award performance monitoring. While no single contractor dominates her portfolio, she consistently engages firms with demonstrated expertise in modular, high-reliability climate control solutions suitable for austere or remote diplomatic posts. Sara’s procurement activity reflects a strict preference for open competition, with 100% of her acquisitions issued without socioeconomic set-asides. This reflects the embassy’s operational imperative to source technically superior and immediately available systems from the broadest possible pool of qualified suppliers, prioritizing mission readiness over socioeconomic targeting. Her contracting patterns indicate a deliberate alignment with Department of State policy that prioritizes performance and reliability over set-aside criteria in critical infrastructure categories. Her primary technical domain is NAICS 333415, encompassing the procurement of air-conditioning, warm air heating, and commercial/industrial refrigeration equipment. She specializes in procuring engineered systems designed for continuous 24/7 operation under extreme environmental conditions, including high-precision HVAC units, chillers, and refrigerant management systems tailored for secure diplomatic facilities. Her expertise lies in evaluating technical specifications, warranty terms, and service support structures for mission-critical environmental control infrastructure.
