Ann M. Calvin

Ann M. Calvin serves as a key procurement lead within the W071 Endist Omaha office under the Department of the Army, overseeing the acquisition of critical infrastructure and support services essential to national defense readiness. Her responsibilities center on managing complex construction and engineering contracts aligned with the Army’s strategic modernization goals, particularly in the development of hardened facilities for nuclear deterrence systems and associated utility corridors. She handles full lifecycle acquisitions—from solicitation through contract award and administration—ensuring compliance with federal regulations and operational requirements for mission-critical military installations. Her work directly supports the sustainment and enhancement of the Army’s physical infrastructure across the continental United States. Calvin maintains long-standing relationships with a core group of contractors including JOHN BOWMAN, INC., PAF ELECTRICAL, INC., HENDRICKSON TRANSPORTATION LLC, PERINI MANAGEMENT SERVICES, INC., and WASHINGTON EQUIPMENT MANUFACTURING COMPANY, INC. These firms are consistently engaged for heavy civil construction, electrical systems integration, specialized transportation logistics, and heavy equipment procurement. Her contracting approach emphasizes performance-based outcomes, technical precision, and contractor reliability, fostering stable, high-capacity partnerships with firms proven in delivering complex defense infrastructure under stringent safety and security standards. There is no set-aside preference in Calvin’s procurement portfolio; all awards are competed fully and openly under unrestricted solicitation criteria. This reflects a mission-driven focus on technical capability and operational readiness over socioeconomic classifications, with all contracts awarded based on merit, past performance, and compliance with stringent military engineering specifications. Her primary procurement focus is concentrated in NAICS 212319—Other Crushed and Broken Stone Mining and Quarrying—indicating a specialized emphasis on aggregate materials and earthwork essential for base construction, runway stabilization, and hardened facility foundations. This technical domain requires deep expertise in geotechnical sourcing, environmental compliance, and logistics coordination for bulk material delivery, underscoring her niche proficiency in supporting large-scale military construction through specialized mineral resource acquisition.
