Harold Kostem

Harold Kostem serves as a Contract Specialist within the Commanding General’s office under the Department of the Navy, where he plays a pivotal role in executing mission-critical acquisitions that sustain operational readiness for naval and marine forces. He manages a diverse portfolio of contracts for maintenance, logistics, and specialized technical support services essential to combat systems, mobility assets, and expeditionary infrastructure. His work ensures timely procurement of mission-enabling solutions across both garrison and deployed environments, aligning with the agency’s strategic priorities of equipment reliability and force sustainability. Kostem routinely handles performance-based service contracts, indefinite-delivery/indefinite-quantity (IDIQ) vehicles, and urgent requirement solicitations under FAR Part 12 and Part 37. Kostem maintains consistent working relationships with a core group of contractors including MANCON LLC, GEMINI TECH SERVICES LLC, CHEMBLE SOLUTIONS, LLC, MICROTECHNOLOGIES LLC, and SAELIG COMPANY, INC., many of whom provide niche technical support, maintenance logistics, and specialized equipment services. His procurement approach emphasizes vendor reliability, past performance, and technical capability, fostering long-term partnerships with firms that demonstrate proven expertise in naval operational environments. A strong advocate for small business participation, Kostem prioritizes Total Small Business Set-Asides under FAR 19.5, which account for over 61% of his awards, reflecting a deliberate strategy to expand economic opportunity among small, non-disadvantaged firms. He also regularly utilizes Service-Disabled Veteran-Owned Small Business (SDVOSB) set-asides, with nearly 4.5% of awards directed to this category, demonstrating alignment with national socioeconomic contracting goals. His primary procurement focus lies in technical services and specialized support, with notable activity in NAICS 488190 (Other Support Activities for Air Transportation), though his portfolio spans a broad range of niche categories including technical training, instrumentation, and specialized manufacturing. Kostem’s expertise centers on procuring mission-critical, non-commodity services that support naval readiness through precision logistics and technical innovation.
