What Yooshin Engineering Corporation does

Yooshin Engineering Corporation (주식회사 유신) is a South Korean civil engineering consulting firm founded in 1966 and headquartered in Seoul, listed on KOSDAQ. The firm delivers end-to-end infrastructure engineering services — feasibility studies, design, construction management, project management consulting, environmental and impact assessment, EPC, and operations and maintenance — across four service divisions: LINK (roads, railways, bridges, airports, ports, tunnels), BASIS (hydrology, water supply/wastewater, geotechnical engineering), HARMONY (urban planning and development, leisure and landscaping), and ETERNITY (new and renewable power, ecological systems, environment). The company has completed 10,911 projects across 67 countries, employs 458 registered engineers (기술사) among a total workforce of 1,001–5,000, and holds 26 overseas offices across 15 countries. Its core technology centers on world-class bridge engineering (Lee Sun-shin Bridge cable-stayed technology, Incheon Bridge, Yavuz Sultan Selim Bridge, Çanakkale Bridge), supported by 8 patents on Lee Sun-shin Bridge methods, 62 additional patents, and 6 new construction technologies.

Revenue is generated through professional-services fees on project contracts won primarily via competitive tendering with Korean government ministries and agencies, multilateral development banks (ADB, World Bank, KOICA, EDCF), and overseas government counterparts, often executed through joint ventures or consortiums with local partners (e.g., Schema Konsult in the Philippines). The firm does not publish pricing; contract values range from hundreds of millions to over ₩39 billion KRW per award, with multi-year billing cadences. Major current clients include the Asian Development Bank, Philippines DPWH/BCDA (Clark Airport runway, Bataan–Cavite Bridge), Korea Hydro & Nuclear Power, Korea Southern Power, Incheon International Airport Corporation, Kenya Ports Authority, and Cambodia MOWRAM. GTM is enterprise field sales driven by competitive bidding, supplemented by earned media through industry awards (Presidential Commendation 2024, Korea Engineering Grand Prize 2025) and investor-relations disclosure on KOSDAQ. Yooshin reported revenue of approximately ₩230 billion KRW in 2024 (down from ~₩263 billion KRW in 2023) and carries a NICE D&B credit rating of A+(e-3+).
