John Vohlken

John D. Vohlken serves as a key procurement lead within the W074 Endist Jacksonville office of the U.S. Army Corps of Engineers, overseeing complex civil infrastructure contracts critical to military readiness and environmental resilience across Florida’s coastal and inland waterways. His portfolio centers on heavy civil engineering acquisitions, particularly dredging, shoreline stabilization, flood control, and ecosystem restoration projects. Vohlken ensures compliance with federal acquisition regulations while aligning procurements with the Department of Defense’s strategic imperatives for infrastructure sustainability and operational readiness. He maintains long-standing relationships with leading maritime and civil construction firms, including FINCANTIERI MARINE REPAIR LLC, GREAT LAKES DREDGE & DOCK CO, LLC, WEEKS MARINE, INC., and MCKENZIE CONSTRUCTION & SITE DEVELOPMENT LLC. These partnerships reflect a preference for experienced contractors with proven expertise in hydraulic engineering, marine construction, and large-scale earthmoving operations. Vohlken’s contracting approach emphasizes performance-based outcomes, technical rigor, and contractor reliability in high-risk, mission-critical environments. While the majority of his acquisitions are open to full and open competition (75.9%), Vohlken consistently allocates a significant portion—nearly 24%—to small business set-asides, including Total Small Business, Service-Disabled Veteran-Owned Small Business, and 8(a) programs. This demonstrates a deliberate commitment to fostering economic opportunity and enhancing contractor diversity within the civil engineering sector, particularly among firms capable of delivering complex environmental and infrastructure solutions. His procurement focus is overwhelmingly concentrated in NAICS 237990 (Other Heavy and Civil Engineering Construction), reflecting deep expertise in large-scale hydraulic and structural projects. He also procures specialized services in boat maintenance, water supply systems, and technical engineering support, underscoring a multidisciplinary approach to sustaining military infrastructure and ecological integrity in sensitive coastal environments.
