Dianne L Haymans

Dianne L. Haymans serves as a Contract Specialist with NAVFACSYSCOM Southeast (N69450), where she plays a pivotal role in executing mission-critical procurement actions to support naval infrastructure readiness across the Southeastern U.S. and overseas operational areas. She manages the full lifecycle of complex construction and facility support contracts, ensuring compliance with federal acquisition regulations and defense-specific requirements. Her portfolio primarily encompasses commercial and institutional building construction, as well as highway, street, and bridge construction projects essential to base operations and force projection. Haymans works closely with program managers, engineers, and legal counsel to align contracting strategies with mission needs, prioritizing timely delivery of resilient infrastructure that supports naval readiness. She maintains established working relationships with a core group of experienced prime contractors, including BL Harbert International LLC, Walsh Federal LLC, Sauer Construction, LLC, McKenzie Construction & Site Development LLC, and Kira Aviation Services LLC. These partnerships reflect a preference for proven performers with demonstrated capacity in large-scale federal construction and facility support services. Haymans fosters collaborative, performance-driven relationships with vendors who consistently meet technical, schedule, and safety standards, ensuring high-quality outcomes across geographically dispersed projects. Her contracting approach is predominantly open competition, with 85.7% of awards issued under no set-aside conditions, reflecting the scale and complexity of the infrastructure missions she supports. However, she actively incorporates 8(a) competed contracts at a rate of 14.3%, demonstrating a measured commitment to socioeconomic programs without compromising mission requirements. Her participation in small business contracting is strategic, aligned with project scope and capability rather than quota-driven targets. Haymans specializes in NAICS 237310 (Highway, Street, and Bridge Construction) and NAICS 236220 (Commercial and Institutional Building Construction), overseeing acquisitions for site development, utilities integration, structural improvements, and facility modernization. Her technical expertise spans civil works, building systems, and base operations support, ensuring that procurements deliver durable, mission-ready infrastructure aligned with Department of Defense standards.
