Roads and Bridges
We establish a foundation for mankind’s growth.
Roads and bridges are social overhead capital facilities linking the main artery of industries and economies as the most fundamental basis of the society. SJ Constructionhas exhibited its high technologies such as PSC-Beam, ST BOX Girder, R/C Rahmen engineering method, etc., as in Buyong Bridge, Geumdong Bridge, and Gugyo Bridge as well as Yeongdong-Yongsan Expressway. Based on its accumulated knowhow, SJ Construction is strengthening the base of the Korean economy as well as taking the lead of various bridge constructions.
Complex and Housing Lot
We have the insight to view and use land lots effectively.
As the industry develops, people are more keenly aware of environments than before. The number one priority is to preserve the original state of nature as fully as possible. SJ Constructionis creating spaces that are beneficial to humanity by participating in complex formation and housing lot development projects, andis also strengthening the supporting base through such projects as Jinju Inno Hub City site preparation.
Tunnels and Railways
We accelerate humanity growth for the new millennium.
As the global society advances, traffic problems have become a serious social issue. Accordingly, various projects to overcome the limit of ground space have been conducted. SJ Construction has conducted such projects as Jinju-Gwayang railroad bed construction despite various challenges including poor natural environments and geographical conditions. We will continue to contribute to the balanced development of national territories by constructing various tunnels and railroads.
Dredging and Harbors
We play an important role in improving the national competitiveness.
Dredging is a construction to carry earth and sand from underwater or maritime areas to another place. As transportation of a large quantity of freight through a port or harbor is widely used, its value is expected to increase. SJ Construction has demonstrated its significant technical development and technical power through such projects as Section 6 of Gyeongin Waterway, Section 20 of Nakdong River, and Pohang-Yeongilman Port. We will continue to put forth efforts with the goal that Korea becomes a country of world-best port cities.
