Ella M Chapman

Ella M. Chapman serves as a Contracting Officer within the Contract Administration Services Division (70RCAS) of the Department of Homeland Security’s Office of Procurement Operations, where she plays a pivotal role in executing mission-critical acquisitions that support national security and operational readiness. Her portfolio centers on professional, scientific, and technical services essential to systems engineering, cybersecurity, and physical science research. She manages full lifecycle contracting actions—from market research and solicitation development to award and administration—ensuring compliance with federal acquisition regulations and alignment with DHS strategic objectives. Her work directly enables the agency’s capacity to maintain resilient infrastructure and advanced technical capabilities. Chapman cultivates collaborative relationships with a diverse range of contractors specializing in management consulting, technical advisory services, and facility leasing. While no single vendor dominates her award portfolio, she consistently engages firms with proven expertise in delivering high-integrity, mission-support services under performance-based contract structures. Her approach emphasizes transparency, competition, and performance accountability, fostering long-term partnerships with vendors capable of meeting complex government requirements without reliance on sole-source justifications. Her contracting patterns reflect a strong preference for full and open competition, with 100% of her acquisitions conducted without set-asides for 8(a), HUBZone, SDVOSB, or other socioeconomic programs. This reflects a strategic focus on maximizing technical capability and value over socioeconomic categorization, consistent with the division’s need for specialized, mission-critical expertise. Chapman’s primary NAICS focus areas—541611 (Administrative Management Consulting), 541690 (Other Scientific and Technical Consulting), and 531120 (Nonresidential Building Lessors)—reveal a specialization in procurement of high-level advisory services, engineering support, and facility infrastructure. She routinely acquires contract vehicles for systems integration, technical risk assessment, and mission-critical facility management, demonstrating deep familiarity with the intersection of federal real property and technical service delivery.
