Holderfield serves as a Contracting Officer for the Department of the Air Force at FA2517 21 Cons Bldg 350, where she manages mission-critical procurement activities focused on infrastructure modernization and operational readiness. Her portfolio centers on engineering services that support the sustainment and enhancement of defense facilities, including the integration of advanced electronic, communication, and fire safety systems. Holderfield is responsible for the full lifecycle of contract actions—from solicitation and evaluation to award and administration—ensuring compliance with federal acquisition regulations and alignment with Air Force strategic priorities. She routinely handles complex, performance-based contracts for technical services requiring high levels of security, precision, and regulatory adherence. Holderfield maintains consistent working relationships with a select group of experienced contractors, including ASTERI CONSULTING SERVICES LLC, AMD INTERNATIONAL TECHNOLOGIES LLC, MCKENZIE CONSTRUCTION & SITE DEVELOPMENT LLC, ARHAB LLC, and PRIMEPRO BUSINESS SOLUTIONS LLC. These partners are frequently engaged for their expertise in facility engineering, systems integration, and mission-critical construction services. Her procurement approach emphasizes proven technical capability, past performance, and operational reliability, fostering long-term vendor partnerships built on accountability and mission alignment. Holderfield’s contracting activity is entirely non-set-aside, with 100% of awards issued under full and open competition. While she does not prioritize socioeconomic set-asides such as 8(a), HUBZone, or SDVOSB programs, her process remains transparent and compliant with all federal procurement mandates. Her focus is on selecting the most qualified vendors based on technical merit and mission suitability, regardless of business size or certification status. Her primary procurement focus is on NAICS 541330 (Engineering Services), reflecting deep specialization in architectural, civil, electrical, and systems engineering for defense infrastructure. She procures services including facility assessments, life-cycle modernization, cybersecurity-integrated communications systems, and fire protection engineering—domains requiring advanced technical knowledge and adherence to military construction standards.
