Jemimah C. Estrella

Jemimah C. Estrella serves as a Contract Administrator for FA4528 5 Cons within the Department of the Air Force, responsible for managing the full lifecycle of procurement actions supporting infrastructure modernization and facility sustainment. She oversees the acquisition of building systems integration services—including electrical, plumbing, HVAC, and roofing—as well as structural construction for commercial, institutional, and industrial facilities. Her role ensures compliance with federal contracting regulations while aligning procurements with the agency’s mission to maintain mission-critical Air Force installations through timely, efficient, and technically sound contract execution. Estrella maintains a consistent working relationship with McKenzie Construction & Site Development LLC, a primary contractor for complex facility upgrades and site development initiatives. Her procurement approach emphasizes collaboration with experienced general contractors capable of delivering integrated building systems under tight operational timelines. She fosters long-term vendor partnerships grounded in performance reliability, regulatory adherence, and responsiveness to facility-specific technical requirements across multiple installation sites. A strong advocate for small business participation, Estrella prioritizes Total Small Business Set-Asides under FAR 19.5, directing 75% of her acquisitions to small businesses. This reflects a deliberate strategy to expand economic opportunity while leveraging the agility and specialized capabilities of small firms in niche construction and maintenance services. Her contracting patterns demonstrate a sustained commitment to socioeconomic goals, with minimal use of unrestricted awards. Her primary procurement focus centers on NAICS 813110 (Religious Organizations), reflecting a unique alignment with faith-based facility support contracts, alongside 811219 (Other Personal Service Activities) and 238990 (All Other Specialty Trade Contractors). This specialization indicates deep expertise in non-traditional construction environments and complex service delivery models requiring coordination between facility operations, environmental compliance, and mission-specific infrastructure needs.
