Founded in 1976, Samho Development is a civil engineering specialty contractor focused on roads, railways, subways, tunnels, and land/industrial complex development.
Unlike general contractors centered on large-scale housing presales, its business is anchored in public-sector infrastructure work such as expressways and railways.
The company operates its own heavy equipment fleet for large-scale earthworks and maintains aggregate and asphalt concrete production facilities, supporting cost competitiveness.
It has expanded into airports, power plants, ports, and industrial site development, and has gained construction experience in advanced-industry infrastructure through civil works tied to the Yongin semiconductor cluster.
Its prime contractors are mainly large builders such as Hyundai Engineering & Construction and SK Ecoplant, and the company has positioned itself as a subcontracting partner to these majors.
As of 1H 2026, the total contract value of major projects involving Hyundai Engineering & Construction and SK affiliates rose year-on-year, and their combined share of major contracts also expanded.
In September 2026, the company secured a portion of a deep underground rainwater tunnel project near Gangnam Station from Hanshin Engineering & Construction, adding a contract equivalent to a significant portion of 2025 consolidated revenue.
Given the nature of the business, public SOC order volume, order backlog, and cost management—rather than private housing cycles or project financing—are the key variables driving results.
