Sherrie Plonski

Sherrie Plonski serves as a Contract Specialist within the W072 Endist Pittsburgh office of the U.S. Army Corps of Engineers, supporting the Department of the Army’s mission to sustain and modernize critical civil infrastructure. She manages the full lifecycle of procurement actions for construction, maintenance, and operational support services related to dams, levees, locks, and water resource systems. Her acquisitions are grounded in federal acquisition regulations and emphasize mission-critical public safety outcomes, with a focus on heavy civil engineering, facilities support, and organizational services essential to federal water resource stewardship. Plonski maintains long-standing relationships with key contractors including MCKENZIE CONSTRUCTION & SITE DEVELOPMENT LLC and C. J. MAHAN CONSTRUCTION COMPANY, LLC, both of which provide specialized expertise in civil works construction and site development. Her contracting patterns reflect a preference for established, experienced vendors with proven track records in complex federal infrastructure projects, while still fostering competitive environments to ensure value and accountability. She collaborates closely with these partners to align technical deliverables with engineering specifications and regulatory compliance standards. Her procurement strategy prioritizes broad market access, with 74.3% of awards issued under no set-aside, reflecting the scale and technical nature of many projects. However, she actively supports small business participation, with 17.1% of awards designated as total small business set-asides and additional allocations for service-disabled veteran-owned and HUBZone firms, demonstrating a balanced commitment to socioeconomic goals without compromising mission readiness. Plonski’s primary procurement focus lies in NAICS 813910 (Business Associations) and 813410 (Civic and Social Organizations), which support administrative and operational functions for infrastructure programs, alongside facilities support services under 561210 and heavy civil construction under 237990. Her expertise spans the procurement of technical services, project management support, and specialized construction activities essential to the Army’s civil works portfolio.
