GS Engineering and Construction said on the 15th that the steel modular multifamily dwellings technology developed by its domestic modular dwellings subsidiary, XiGeist, obtained recognition as industrialized dwellings from the Ministry of Land, Infrastructure and Transport.
Until now, the maximum number of floors to receive recognition as industrialized dwellings from the Ministry of Land, Infrastructure and Transport using steel modular technology was 12. This time, XiGeist's steel modular technology received recognition that allows application to multifamily dwellings up to 18 floors.
An official at GS Engineering and Construction said, "The ministry's recognition is significant in that it takes the potential of high-rise steel modular multifamily dwellings one step further."
Recognition as industrialized dwellings by the ministry is a nationally certified system granted to modular dwellings that meet quality, safety, and durability standards through standardized production processes, in accordance with the Housing Act and the rules on standards for housing construction.
XiGeist's steel modular multifamily dwellings technology is a system that modularizes the entire area by using steel for structural members such as columns and beams, while combining materials such as concrete slabs and gypsum boards for the remaining frames, floors, walls, and ceilings. It also meets the three-hour fire resistance standard, long seen as a technical hurdle to commercializing high-rise modular dwellings, raising confidence in the safety of high-rise steel modular dwellings.
Meanwhile, XiGeist operates a dedicated modular production plant in Dangjin, South Chungcheong Province, and has systematized the entire process from modular design to manufacturing and construction. Beyond steel modular multifamily dwellings technology, it has also secured technologies to enhance modular quality—such as fire-resistant structures, inter-floor noise blocking, and sound insulation performance—and technologies to reduce energy use.
