Darius A. Simpkins

Darius A. Simpkins serves as a key procurement lead within the 0409 Aq Hq Contract office of the Department of the Army, responsible for managing complex facility infrastructure and equipment contracts that sustain operational readiness at U.S. Army garrisons and overseas installations. His work directly supports the maintenance and modernization of critical military infrastructure—including airfields, utilities, and climate-controlled facilities—particularly in European theaters. He oversees the acquisition of specialized construction services and high-integrity mechanical systems, ensuring compliance with military engineering standards and expeditionary operational requirements. His portfolio centers on mission-critical contracts that require technical precision, rapid deployment capability, and long-term lifecycle support. Simpkins maintains consistent contracting relationships with PAE Applied Technologies LLC and BSH Hausgeräte B.V., leveraging their expertise in large-scale facility sustainment and industrial-grade HVAC and compressor systems. His partnerships reflect a preference for established contractors with proven track records in military-grade environmental control and mechanical systems integration. These vendors are selected for their ability to deliver standardized, durable equipment and services under austere conditions, often requiring adherence to NATO and U.S. Army technical specifications. His procurement approach prioritizes reliability, interoperability, and supply chain resilience over competitive bidding alone. Simpkins’ contracting activity is entirely non-set-aside, with 100% of awards issued under full and open competition. This reflects a strategic focus on technical capability and mission-critical performance over socioeconomic preferences, aligning with the high-stakes nature of overseas infrastructure sustainment. While small business participation is not formally prioritized in his portfolio, his awards remain accessible to all qualified vendors capable of meeting stringent military specifications. His primary procurement focus lies in NAICS 333912 (Air and Gas Compressor Manufacturing) and 238220 (Plumbing, Heating, and Air-Conditioning Contractors), underscoring deep expertise in industrial HVAC systems, compressed air infrastructure, and climate control for military facilities. He routinely procures mission-critical equipment such as high-capacity air compressors, modular climate units, and integrated utility systems designed for continuous operation in deployed environments.
