Jeffrey C. Grelck serves as a Contract Specialist within the Department of the Air Force’s FA4610 30 Cons Pk facility, supporting the Space Systems Command’s mission to sustain critical infrastructure at Vandenberg Space Force Base. He manages a diverse portfolio of construction, facilities support, and specialized technical service acquisitions essential to maintaining operational readiness for national security space missions. His work encompasses full lifecycle contract administration—from solicitation and source selection to award and closeout—ensuring compliance with FAR, DFARS, and agency-specific requirements for mission-critical infrastructure resilience. Grelck maintains consistent working relationships with key contractors including MCKENZIE CONSTRUCTION & SITE DEVELOPMENT LLC, DIVERSE PEST MANAGEMENT, TECH O. R., LLC, KING FREIGHT LLC, and DARBONNIER TACTICAL SUPPLY LLC, reflecting a balanced mix of general construction, environmental services, logistics, and tactical supply vendors. His procurement patterns emphasize collaboration with firms possessing niche expertise in facility maintenance, utility systems support, and secure site operations, fostering long-term vendor partnerships grounded in performance reliability and mission alignment. His contracting approach demonstrates strong support for small business participation, with nearly 40% of awards structured as total small business set-asides under FAR 19.5, and significant allocation to service-disabled veteran-owned small businesses (14.3%) and economically disadvantaged WOSBs (3.6%). He actively leverages HUBZone and SDVOSB authorities to enhance socioeconomic diversity in the vendor base while maintaining rigorous performance standards. Grelck’s primary procurement focus lies in NAICS categories 236220 (Commercial and Institutional Building Construction), 238990 (All Other Specialty Trade Contractors), and 423120 (Motor Vehicle Supplies and New Parts Merchant Wholesalers), reflecting his specialization in facility modernization, specialized trade services, and mission-critical logistics support. His domain expertise centers on sustaining aging infrastructure through compliant, performance-based contracting that ensures uninterrupted operational capability for national security space assets.
