Mark E. Puffenbarger serves as a Contract Specialist within the Department of the Air Force’s FA4418 628 Cons Pk unit, responsible for managing the acquisition of mission-enabling infrastructure and facility support services at Joint Base Charleston and associated installations. He plays a pivotal role in executing construction, maintenance, and operational sustainment contracts critical to airfield readiness, utility reliability, and base infrastructure resilience. His portfolio includes a broad range of procurement actions under the Federal Acquisition Regulation, with emphasis on service-based contracts that support facility operations, environmental compliance, and mission-critical logistics. Puffenbarger maintains consistent working relationships with a select group of contractors, including MCKENZIE CONSTRUCTION & SITE DEVELOPMENT LLC for site development and civil works, PROTECT KITCHEN EXHAUST CLEANING, LLC for specialized facility maintenance, ACCESS PORTABLE TOILETS INC for temporary sanitation solutions, and ML Armaments LLC for security-related equipment and services. These partnerships reflect a preference for niche, high-reliability vendors capable of delivering specialized, mission-aligned services under tight operational timelines and stringent compliance standards. His procurement strategy prioritizes small business participation, with 50% of acquisitions structured as total small business set-asides under FAR 19.5, and an additional 8.3% designated for HUBZone firms. This reflects a deliberate effort to foster economic opportunity within the defense industrial base while ensuring access to capable, responsive vendors. He rarely employs no-set-aside procurements, indicating a strong institutional commitment to socioeconomic contracting goals. Puffenbarger’s primary NAICS focus areas include 561790 (other building services), 518210 (data infrastructure services), 423620 (household appliance wholesale), 423210 (furniture wholesale), and 333924 (industrial material handling equipment). These reflect a diverse yet operationally grounded procurement profile spanning facility support systems, logistical equipment, and digital infrastructure—demonstrating technical fluency across both traditional construction support and modernized base operations domains.
