Business
Tuksu Engineering & Construction Ltd. is a South Korea-based civil engineering and specialized construction company engaged primarily in high-difficulty underground infrastructure, deep foundation engineering, and heavy industrial construction. Founded in 1971 and headquartered in Seoul, South Korea, the company delivers engineering, procurement, and construction (EPC) solutions across domestic and overseas markets, including an established international branch in Singapore. The company categorizes its operations into specialized civil engineering, heavy industrial plant construction, and equipment operations, offering products and services comprising trenchless underground crossing solutions utilizing Front Jacking (FJ), Endless Self-Advancing (ESA), R&C, and Pipe Roof methods; mechanized tunnel excavation utilizing Shield Tunnel Boring Machine (TBM) and Semi-Shield TBM technologies; deep foundation and geotechnical works including BAUER BG large-diameter cast-in-place bored piling, Reverse Circulation Drilling (RCD), and diaphragm slurry wall construction; general civil works covering highways, bridges, subways, and high-speed railway networks; industrial manufacturing facilities such as steel mills and automotive painting plants; environmental infrastructure including water treatment and pipeline installations; and heavy construction equipment leasing, fabrication, and specialized tooling services. In recent strategic developments, the company strengthened its financial and capital structure through the issuance of 12 billion South Korean won in private convertible bonds to finance operational capital requirements and expand investments in specialized tunneling machinery. Additionally, Tuksu Engineering & Construction Ltd. continues to broaden its project backlog by deploying advanced non-disruptive urban tunneling technologies and deep geotechnical methods across high-density metropolitan rail expansions, major cross-sea bridge projects, and regional infrastructure developments throughout South Korea and Southeast Asia.
