Han Ol Sok

Han Ol Sok serves as a key procurement lead within the 0411 Aq Hq Contract Augmented unit of the Department of the Army, overseeing the acquisition of facility sustainment, modernization, and infrastructure support services critical to U.S. Army garrison operations, particularly at overseas installations such as USAG Humphreys and USFK. Responsible for managing complex construction and utility contracts, Han ensures the integrity of mission-critical infrastructure by aligning procurement strategies with Army installation resilience goals. Their portfolio primarily encompasses commercial and industrial building construction, electrical distribution systems, and related civil works, requiring deep technical oversight and compliance with military construction standards. Han Ol Sok maintains consistent working relationships with a core group of established contractors, including GLOBAL SYSTEMIZED INDUSTRY, 09CLEAN CO., LTD, KOREA CONTAINER POOL CO., LTD, NOKHWACHANGJO, and GLOBAL COMPANY ALLIANCE CO., LTD. These partnerships reflect a preference for experienced, regionally grounded vendors with proven capabilities in military facility maintenance, modular construction, and utility infrastructure support. Procurement activities are characterized by long-term operational continuity, with repeat engagements based on performance reliability and adherence to Army technical specifications. There is no set-aside preference in Han Ol Sok’s contracting portfolio; all acquisitions are conducted as full and open competitions. This reflects a strategic focus on maximizing competition among qualified, capable vendors rather than socioeconomic set-asides, prioritizing mission readiness and technical competency over socioeconomic classifications. The primary procurement focus lies in NAICS 236220 (Commercial and Institutional Building Construction), followed by industrial construction (236210) and electric power distribution (236220). Han specializes in procuring services related to structural renovation, precast concrete systems, and utility upgrades essential to sustaining operational readiness at high-density military installations. Their expertise centers on integrated facility lifecycle management, ensuring that construction and maintenance contracts deliver durable, code-compliant, and mission-essential infrastructure.
