Stephen Kolokithias

Stephen Kolokithias serves as a secondary procurement professional within the W2SD Endist Philadelphia office of the U.S. Army Corps of Engineers, supporting critical civil infrastructure and maritime engineering initiatives. His role involves facilitating the acquisition of engineering services, dredging, and heavy construction projects essential to maintaining coastal resilience, navigation channels, and military installation infrastructure. He contributes to the agency’s mission by ensuring compliant, timely procurement of technical services aligned with national defense priorities, often coordinating with senior contracting officers on complex, multi-year engineering contracts. Kolokithias regularly engages with a core group of established contractors including Boh Environmental, L.L.C., CONRAD SHIPYARD, L.L.C., HDR ARCHITECTURE, INC., BUCHART HORN INC, and NORFOLK DREDGING COMPANY. These partnerships reflect a preference for firms with proven expertise in marine engineering, environmental remediation, and large-scale civil construction. His procurement patterns indicate close collaboration with vendors possessing specialized capabilities in hydraulic modeling, shoreline protection, and navigation system modernization, often requiring deep technical vetting and performance-based contract structures. His acquisition strategy prioritizes small business participation, with over half of all procurements structured as Total Small Business Set-Asides under FAR 19.5. This reflects a deliberate commitment to fostering economic opportunity among small, locally based engineering and construction firms, while maintaining compliance with socioeconomic contracting goals. Though no set-aside type dominates exclusively, the consistent use of small business set-asides underscores a strategic emphasis on broadening vendor diversity within the civil works sector. The agency’s procurement focus centers on NAICS 541330 (Engineering Services), with significant activity in surveying and mapping (541370) and geophysical surveying (541360), alongside heavy civil construction (237990). Kolokithias supports the acquisition of hydrographic surveys, topographic mapping, structural design, and dredging operations—technical domains requiring precision, regulatory adherence, and integration with federal environmental standards. His work ensures the Army’s infrastructure remains operationally viable and strategically resilient.
