Nathan Ryan Kloeckler

Nathan Kloecker serves as a key procurement lead within the W076 Endist Tulsa office under the Department of the Army, responsible for managing complex civil engineering and facility sustainment contracts critical to Army installation readiness. His role centers on executing acquisitions for heavy civil construction, infrastructure modernization, and environmental compliance services that support military operations and public land stewardship. Kloecker handles a diverse portfolio of contract types, including firm-fixed-price and cost-reimbursement instruments, primarily for large-scale construction and maintenance projects requiring stringent regulatory adherence and technical oversight. He maintains consistent working relationships with established prime contractors including BL Harbert International LLC, Alberici Constructors Inc., MCMillen, Inc., and McKenzie Construction & Site Development LLC, reflecting a preference for experienced firms with proven track records in federal civil works. These partnerships are characterized by long-term engagement on multi-year infrastructure programs, with frequent recompetes and task order modifications that require deep technical coordination and performance monitoring. Kloecker demonstrates a strong commitment to small business participation, with nearly 47% of his acquisitions structured as total small business set-asides under FAR 19.5, and an additional 6.2% allocated to 8(a) and HUBZone programs. His contracting patterns reflect deliberate efforts to foster economic opportunity among disadvantaged and geographically targeted small businesses while maintaining competitive integrity across solicitations. His procurement focus is concentrated in NAICS 237990 (Other Heavy and Civil Engineering Construction) and 236220 (Commercial and Institutional Building Construction), with significant activity in highway, water/sewer, and electrical systems infrastructure. He specializes in acquiring integrated construction services that combine structural, environmental, and utility components, requiring multidisciplinary contractor capabilities and compliance with Army Corps of Engineers and EPA standards.
