Shanna Guillen

Shanna Guillen serves as a key procurement professional within the FA4626 341 Cons Lgc, a civil engineering and infrastructure sustainment unit under the Department of the Air Force. She manages acquisition programs focused on maintaining and modernizing mission-critical facilities, including HVAC, electrical, plumbing, and structural systems essential to Air Force operational readiness. Her responsibilities encompass the full lifecycle of contract execution—from requirements development and market research to award and performance oversight—ensuring compliance with federal acquisition regulations and defense-specific standards. Guillen routinely handles service-based contracts for facility maintenance, utility system upgrades, and environmental compliance, aligning procurements with the agency’s strategic goals of resilience, safety, and long-term asset sustainability. Her primary contractor relationships center on MID MOUNTAIN BOILER AND STEAM, INC., a specialized vendor providing industrial mechanical systems maintenance and repair services. Guillen fosters long-term, performance-based partnerships with contractors who demonstrate technical expertise in facility infrastructure, often leveraging task order contracts and indefinite-delivery/indefinite-quantity (IDIQ) mechanisms to ensure responsive, scalable support across multiple installations. Her procurement approach emphasizes reliability, regulatory adherence, and operational continuity, favoring vendors with proven experience in military-grade facility sustainment. Guillen demonstrates a strong commitment to small business participation, with 66.7% of her acquisitions set aside for total small businesses under FAR 19.5. Her contracting patterns reflect a deliberate strategy to maximize socioeconomic opportunities, consistently prioritizing small business participation without reliance on specialized set-asides like 8(a) or HUBZone. This approach ensures broad vendor engagement while maintaining competitive rigor and mission alignment. Her procurement focus is concentrated in NAICS categories related to facility services, including commercial and industrial machinery repair (811310), pest control (561710), janitorial services (561720), and drycleaning and laundry (812320). These reflect her domain expertise in non-military-specific but mission-critical support services that sustain daily operations across Air Force installations, ensuring both compliance and readiness through specialized, localized vendor networks.
