Shanna Guillen

Shanna Guillen supports critical infrastructure sustainment efforts within the FA4626 341 Cons Lgc, a unit under the Department of the Air Force responsible for maintaining and modernizing mission-critical civil engineering assets across Air Force installations. Her procurement activities center on facility services that ensure operational readiness, including HVAC, plumbing, electrical systems, and environmental infrastructure. She manages a diverse portfolio of service-based acquisitions aligned with the agency’s mandate to uphold resilient, safe, and compliant physical installations, often coordinating complex, multi-year maintenance and repair contracts under FAR Part 12 and Part 13 procedures. Guillen maintains consistent working relationships with MID MOUNTAIN BOILER AND STEAM, INC., a key vendor specializing in boiler systems and steam infrastructure maintenance, reflecting a pattern of long-term, performance-based partnerships with niche technical service providers. Her contracting approach emphasizes reliability, compliance, and mission continuity, frequently engaging contractors with proven expertise in facility systems integration, utility maintenance, and industrial environmental services. These relationships are characterized by repeat engagement and performance-driven contract modifications rather than competitive bidding alone. Her procurement portfolio demonstrates a strong preference for open competition, with 90% of awards issued without set-aside restrictions, indicating a focus on technical capability over socioeconomic categorization. However, she consistently allocates 10% of awards to Total Small Business Set-Asides under FAR 19.5, demonstrating a measured but deliberate commitment to small business participation without compromising mission-critical service standards. Guillen’s primary procurement focus lies in NAICS 811219 (Other Commercial and Industrial Machinery and Equipment Repair), reflecting expertise in maintaining complex facility systems. She also regularly procures services under NAICS 562991 (Other Waste Management Services), 812320 (Drycleaning and Laundry Services), 561710 (Pest Control), and 812210 (Funeral Services), indicating a broad scope of facility support operations. Her technical domain spans environmental compliance, utility infrastructure, and installation-wide service sustainment, requiring deep understanding of DoD facility standards and regulatory frameworks.
