Technical Solution

We are improving our technological competitiveness by providing distinctive technology from the bidding stage. We make significant contributions to the successful completion of projects by applying various methods to fields such as the automated caisson curing system, floating-structure design and construction technology, intelligent multi-grouting (IMG) system, and vertical pipe cooling method. Moreover, we analyze successful and failed cases of previous projects to reduce technical risk in ongoing construction sites. Based on the analysis result, we are pre-emptively providing technical solutions that can enhance the quality and productivity of the site.
