Cassaundra D Mulligan

Cassaundra D. Mulligan serves as a Contract Specialist with NAVFACSYSCOM Southeast (N69450), where she plays a pivotal role in executing mission-critical acquisitions to support naval infrastructure readiness across the Southeastern U.S. and overseas operational areas. She manages the full lifecycle of procurement actions for commercial and institutional construction, facilities support services, and base operations maintenance, ensuring compliance with FAR, DFARS, and Navy-specific acquisition policies. Her work directly enables the agency’s mission to deliver resilient, high-performance facilities by securing timely and cost-effective contracting solutions aligned with strategic infrastructure priorities. Mulligan maintains strong, recurring partnerships with key contractors including BL Harbert International LLC, Walsh Federal LLC, Sauer Construction, LLC, McKenzie Construction & Site Development LLC, and Kira Aviation Services LLC. These relationships reflect a consistent pattern of engaging established firms with proven capabilities in complex construction and facility operations, often involving multi-year task orders and indefinite-delivery/indefinite-quantity (IDIQ) contracts. Her procurement approach emphasizes performance-based outcomes, risk mitigation, and contractor accountability in high-stakes environments. Her contracting portfolio demonstrates a primary focus on open competition, with 64.7% of awards issued without set-asides, while maintaining a meaningful commitment to small business participation—29.4% of awards are structured as total small business set-asides under FAR 19.5, and 5.9% are HUBZone set-asides. This balanced approach ensures broad market access while actively promoting socioeconomic goals within the defense construction sector. Mulligan’s technical expertise centers on NAICS 236220 (Commercial and Institutional Building Construction), which drives over 40% of her acquisitions, followed by facilities support services (561210) and janitorial services (561720). She routinely procures turnkey construction, maintenance, roofing, and heavy civil engineering services, demonstrating deep familiarity with building systems, utility integration, and operational sustainment requirements critical to naval installations.
