Peter G. Zizos

Peter G. Zizos serves as a key procurement lead within the W2SD Endist Baltimore office of the U.S. Army Corps of Engineers, supporting the Department of the Army’s mission to deliver critical infrastructure and facility support across military installations. He manages a diverse portfolio of construction and civil engineering contracts, ensuring timely delivery of facilities, environmental remediation, and structural systems essential to operational readiness. His acquisitions span the full lifecycle of federal construction projects, from planning and design through execution and closeout, with a strong emphasis on compliance with FAR and Army-specific contracting protocols. Zizos maintains established working relationships with a core group of experienced contractors, including GRUNLEY CONSTRUCTION CO., INC., GREAT LAKES DREDGE & DOCK CO, LLC, and CURTIN MARITIME CORP, among others. These partnerships reflect a preference for vendors with proven expertise in heavy civil works, marine construction, and large-scale institutional building projects. His procurement approach emphasizes performance-based contracting, leveraging past performance evaluations and technical capability assessments to ensure contractor reliability and mission alignment. His contracting patterns demonstrate a strong commitment to small business participation, with nearly 50% of awards structured as total small business set-asides under FAR 19.5 and an additional 6.3% reserved for service-disabled veteran-owned small businesses. While no set-aside remains the largest category, his consistent use of socioeconomic programs underscores a deliberate strategy to foster vendor diversity and enhance competition within the defense construction sector. Zizos specializes in procurements under NAICS 237990 (Other Heavy and Civil Engineering Construction) and 236220 (Commercial and Institutional Building Construction), with significant activity in poured concrete foundations, electrical systems, and building finishing. His technical domain expertise centers on complex infrastructure projects requiring coordination of multiple trades, environmental compliance, and adherence to military construction standards, ensuring durable, mission-critical outcomes.
