Marilyn MacTagggart

Marilyn MacTaggart serves as a key procurement lead within the FA4418 628 Cons Pk unit of the Department of the Air Force, responsible for managing construction and infrastructure support contracts critical to operational readiness at Joint Base Charleston and associated installations. Her work directly supports the agency’s mission to sustain and modernize military facilities through timely, compliant acquisition of mission-enabling services. She routinely handles complex construction and maintenance procurements under FAR Part 36, with a focus on design-build and performance-based contracting methods to ensure resilience of airfield, utility, and environmental systems. MacTaggart maintains strategic relationships with a select group of specialized contractors, including MCKENZIE CONSTRUCTION & SITE DEVELOPMENT LLC for facility construction, PROTECT KITCHEN EXHAUST CLEANING, LLC for critical facility hygiene services, ACCESS PORTABLE TOILETS INC for temporary sanitation support, and ML Armaments LLC for security-related infrastructure enhancements. Her contracting patterns reflect a preference for long-term, performance-driven vendor partnerships that prioritize reliability, safety compliance, and rapid response capabilities essential to military operations. She demonstrates a strong commitment to socioeconomic contracting, consistently directing 80% of her portfolio toward small business set-asides—primarily Service-Disabled Veteran-Owned Small Business (SDVOSB) and Total Small Business (FAR 19.5) set-asides—reflecting a deliberate strategy to foster veteran entrepreneurship and local economic resilience. Only 20% of acquisitions are conducted without set-aside restrictions, typically for specialized or time-sensitive requirements. Her procurement focus is concentrated in NAICS 236220 (Commercial and Institutional Building Construction) and 237310 (Highway, Street, and Bridge Construction), underscoring expertise in facility modernization, site development, and transportation infrastructure upgrades. She specializes in acquiring services that ensure structural integrity, utility continuity, and environmental compliance across high-priority defense installations.
