H-PLUS ECO LTD. specializes in technical services supporting critical infrastructure integrity for U.S. Department of Defense installations, with a focus on water distribution system inspections, preventive maintenance, tank integrity assessments, and radon mitigation studies. The contractor delivers professional environmental and engineering services tailored to military base operations, conducting field assessments, compliance evaluations, and preliminary engineering studies to ensure regulatory adherence and long-term operational resilience.

The company maintains a consistent relationship with the Department of Defense, providing mission-critical environmental and infrastructure support services across multiple U.S. military installations, including Fleet Activities Chinhae and installations under U.S. Army Garrison Humphreys.

H-PLUS ECO LTD. operates primarily within NAICS 541990, which encompasses specialized professional services not elsewhere classified—specifically, environmental engineering, infrastructure assessment, and technical advisory services for federal facilities. The firm positions itself as a niche provider of applied environmental and infrastructure diagnostics for defense and public safety environments, distinguishing itself through targeted, field-based technical execution rather than broad-scale consulting. The entity is structured as an 8H concern, indicating it is a small business owned and controlled by a Hawaiian Native organization, with its headquarters located in Seoul, South Korea. While no federal certifications are listed, its geographic presence supports international defense logistics operations, enabling responsive technical support to U.S. military installations in the Indo-Pacific region. The company’s market positioning reflects a strategic alignment with overseas DoD infrastructure needs, leveraging localized technical capacity to serve global defense missions.
