TSgt Jesus Diaz

TSgt Jesus Diaz serves as the primary contracting representative for the FA4418 628th Construction Squadron under the Department of the Air Force, responsible for managing mission-critical construction and infrastructure support acquisitions at Joint Base Charleston and associated installations. He oversees the full lifecycle of procurement actions for facility sustainment, airfield modernization, and utility system enhancements, ensuring compliance with Department of Defense construction standards and environmental regulations. His portfolio focuses on delivering resilient, mission-enabling infrastructure through timely and compliant contract execution, directly supporting operational readiness across Air Force installations. Diaz maintains consistent working relationships with key contractors including MCKENZIE CONSTRUCTION & SITE DEVELOPMENT LLC for site development and facility upgrades, PROTECT KITCHEN EXHAUST CLEANING, LLC for specialized environmental compliance services, ACCESS PORTABLE TOILETS INC for temporary sanitation support, and ML Armaments LLC for security-related hardware. These partnerships reflect a preference for established vendors with proven track records in military construction and facility operations, characterized by repeat engagements and performance-based contract management. Diaz’s procurement activity is exclusively non-set-aside, with 100% of awards issued under full and open competition. This reflects a strategic emphasis on leveraging broad market capability to meet urgent infrastructure demands, rather than targeting socioeconomic categories such as 8(a), HUBZone, or SDVOSB programs. His approach prioritizes technical capability, past performance, and schedule reliability over socioeconomic preferences. His primary procurement focus is on NAICS 332510 (Hardware Manufacturing), indicating a strong specialization in procuring durable, mission-specific hardware such as security fixtures, structural components, utility control systems, and facility-related mechanical and electrical equipment. This technical domain expertise underscores his role in acquiring engineered solutions that directly support the operational integrity and long-term resilience of Air Force infrastructure.
