KUMSUNG CONSTRUCTION CO., LTD.

KUMSUNG CONSTRUCTION CO., LTD. specializes in the construction, repair, and modernization of military infrastructure across U.S. Army and Air Force installations in Korea. Their core capabilities center on commercial and institutional building construction, with demonstrated expertise in facility upgrades including electrical system installations, underground power line deployment, SCADA wiring repairs, fire suppression system replacements, and range maintenance. They execute complex, mission-critical tasks under strict operational constraints, including the installation of portable power systems, antenna tower construction, and stormwater damage mitigation—often in active duty environments. Their technical proficiency includes working with specialized defense systems, integrating utility infrastructure into existing facilities, and performing precision repairs on sensitive military assets without disrupting operations. The contractor maintains a consistent, long-standing relationship with the Department of Defense, delivering construction and maintenance services across multiple U.S. military bases in Korea, including USAG Humphreys and Osan Air Base. Their work supports base resilience, safety compliance, and mission readiness through timely execution of O&M and facility sustainment projects. KUMSUNG’s industry focus is firmly rooted in NAICS 236220 (Commercial and Institutional Building Construction), where they deliver mission-critical infrastructure upgrades for defense installations. Their secondary focus in NAICS 236210 (Industrial Building Construction) reflects experience with specialized logistics and utility systems, positioning them as a niche provider for DoD facility modernization in high-security, overseas operational theaters. As a 2L entity based in Daejeon, South Korea, KUMSUNG operates as a locally embedded contractor with deep regional familiarity. While no federal certifications are listed, their sustained contract activity with the DoD indicates proven reliability in meeting stringent military construction standards and regulatory requirements in austere environments.
