Rosa I Diaz

Rosa I. Diaz serves as a Contract Specialist at W6QM MICC-JB Lewis-McChord under the Department of the Army, where she plays a critical role in executing procurement actions that sustain the operational readiness of Joint Base Lewis-McChord. She manages a diverse portfolio of service-based acquisitions focused on facility maintenance, environmental compliance, and infrastructure support, ensuring mission-critical environments remain safe, functional, and compliant with federal standards. Her work directly supports the base’s strategic priorities in energy efficiency, waste management, and building systems integrity, utilizing full and open competition alongside targeted set-asides to meet socioeconomic objectives. Diaz maintains primary contracting relationships with the Port of Moses Lake and a range of specialized service providers, fostering long-term vendor partnerships grounded in performance accountability and regulatory adherence. Her procurement patterns reflect a preference for established contractors with proven capabilities in base support services, while consistently encouraging new entrants through transparent solicitation practices and clear evaluation criteria. She collaborates closely with program managers and environmental compliance teams to align contracting outcomes with operational needs. Her contracting approach demonstrates a strong commitment to small business participation, with approximately 31.6% of her awards directed toward small business set-asides, including Total Small Business, Women-Owned Small Business, and 8(a) competed contracts. While the majority of her acquisitions remain open to all competitors, she actively leverages socioeconomic programs to expand vendor diversity and enhance competition within the base support services sector. Diaz’s technical expertise centers on NAICS codes 562998 (miscellaneous waste management), 238320 (painting and wall covering), 561790 (building services), and 238220 (plumbing, heating, and air-conditioning), reflecting a deep specialization in facility sustainment and environmental services. She routinely procures maintenance, repair, and operational support services essential to the daily function of military installations, ensuring compliance with federal environmental and safety regulations while optimizing lifecycle performance of base infrastructure.
