Jeffrey Grelck

Jeffrey Grelck serves as a key procurement lead within the Space Systems Command’s FA4610 30 Cons Pk facility, supporting the operational resilience of critical national security space infrastructure at Vandenberg Space Force Base. He manages a diverse portfolio of construction, maintenance, and technical support acquisitions essential to sustaining launch and test site capabilities. His work ensures the integrity of facilities, utilities, and environmental systems underpinning space mission readiness, with a focus on site preparation, building construction, and specialized equipment maintenance. Grelck’s acquisitions are mission-critical, requiring strict adherence to defense infrastructure standards and rapid response to evolving operational demands. Grelck maintains consistent partnerships with a core group of contractors including MCKENZIE CONSTRUCTION & SITE DEVELOPMENT LLC for site development, DIVERSE PEST MANAGEMENT for environmental compliance, TECH O. R., LLC for technical system maintenance, and KING FREIGHT LLC for logistics support. These relationships reflect a preference for established, reliable vendors with proven experience in military-grade infrastructure environments. His contracting approach emphasizes performance-based outcomes, long-term vendor reliability, and compliance with defense-specific safety and security protocols. His procurement patterns show a strong preference for open competition, with 83.3% of awards issued without set-aside designations, indicating a focus on broad market access and technical capability over socioeconomic preferences. Nevertheless, he consistently allocates 16.7% of awards to total small business set-asides under FAR 19.5, demonstrating a measured but deliberate commitment to small business participation within the constraints of mission-critical timelines and technical requirements. Grelck’s primary procurement focus lies in NAICS 238910 (Site Preparation Contractors) and 236220 (Commercial and Institutional Building Construction), with significant activity in 334512 (Environmental Control Equipment) and 811310 (Industrial Machinery Repair). He routinely procures specialized infrastructure services including earthwork, HVAC integration, security system upgrades, and maintenance of mission-critical environmental controls—reflecting deep expertise in defense facility sustainment and technical systems resilience.
