Nathaniel Leyba

Nathaniel Leyba serves as the primary procurement lead for W071 Endist Kansas City, a U.S. Army installation support agency under the Department of Defense. In this role, he manages the acquisition of civil engineering, facility maintenance, and environmental services critical to sustaining military infrastructure readiness. His responsibilities encompass the full lifecycle of contract execution—from market research and solicitation development to award and performance oversight—ensuring compliance with federal acquisition regulations and mission-aligned outcomes. Leyba routinely handles complex, multi-year construction and service contracts that support Army installations, including water systems, roadways, housing, and environmental remediation projects. He maintains sustained working relationships with a core group of prime contractors, including HYDROGEOLOGIC, INC., BURNS & MCDONNELL ENGINEERING COMPANY, INC., and HGL-APTIM TECHNOLOGIES JV LLC, among others. These partnerships reflect a preference for firms with demonstrated expertise in heavy civil engineering, environmental management, and integrated facility services. Leyba’s procurement approach emphasizes collaboration with experienced, technically capable vendors capable of delivering mission-critical infrastructure under stringent military standards. Leyba demonstrates a strong commitment to socioeconomic contracting, with over 76% of his acquisitions set aside for small businesses under FAR 19.5. He consistently prioritizes small business participation, with a notable emphasis on service-disabled veteran-owned small businesses (SDVOSB), reflecting the agency’s alignment with national goals for veteran economic inclusion. His contracting patterns reveal a deliberate strategy to expand opportunities for qualified small and emerging firms while maintaining performance reliability. His primary technical focus lies in NAICS 237990 (Other Heavy and Civil Engineering Construction), with significant activity in landscaping, janitorial services, and water/sewer infrastructure. This reflects deep expertise in facility sustainment, environmental compliance, and mission-critical civil works—ensuring Army installations remain operational, safe, and resilient.
