Song Da 12 JSC is a Vietnam-based construction and engineering enterprise primarily engaged in the execution of civil, industrial, transportation, and major energy infrastructure projects. Founded in 1980 and headquartered in Hanoi, Vietnam, the company operates as a key construction subsidiary of state-affiliated Song Da Corporation. Song Da 12 JSC organizes its operational capabilities across three core business segments: Construction and Installation, Industrial Production and Building Materials, and Real Estate and Infrastructure Investment. The company delivers an integrated portfolio of specialized engineering and contracting services, including general contracting for civil and industrial facilities; large-scale underground tunneling, rock blasting, and earthmoving works; specialized foundation engineering and geological grouting; construction of concrete and earth-fill dams for hydropower and irrigation networks; assembly and installation of electromechanical equipment, high-voltage transmission lines, and substations; transportation infrastructure engineering, including highways, bridges, and urban arterial roads; and the leasing, repair, and maintenance of specialized heavy construction machinery. In its industrial manufacturing operations, the company produces and supplies ready-mix concrete; precast reinforced concrete structures and culverts; crushed stone aggregates and industrial sand; fabricated steel structures; and customized architectural metal components. The company serves public sector agencies, state utilities, and private industrial developers across Vietnam, with selected project execution extending into neighboring markets such as Laos. In recent developments, Song Da 12 JSC has implemented comprehensive operational and financial restructuring programs to address legacy liabilities, accelerate the recovery of overdue receivables from major hydropower ventures, and improve balance sheet liquidity under UPCoM trading supervision. Strategically, the enterprise has reoriented its business development efforts toward bidding on national transportation corridors, municipal environmental infrastructure, and clean energy construction, while divesting non-core assets, optimizing heavy equipment utilization, and streamlining internal administrative units to strengthen project execution margins and bolster operational stability.
