GS Engineering and Construction said on the 3rd that on the 31st it held an off-site construction (OSC) technology seminar on "innovation in safety, eco-friendliness, and future housing" at GPC, its precast (PC) concrete manufacturing subsidiary in Eumseong, North Chungcheong.
The seminar, held together with Korea Land & Housing Corporation (LH) and the Korea Association of Structural Engineers, showcased products and structural technology for next-generation PC multiunit dwellings that will lead the OSC era.
At the seminar, GS Engineering and Construction unveiled an OSC method that combines factory production with on-site assembly under the theme "a new proposal that responds to changing customer lifestyles." It is a next-generation model of dwellings integrated with the living philosophy of Xi.
The "Xi PC platform" introduced that day adopts a rigid frame structure that allows flexible floor plans by making units non-load-bearing, compared with the existing wall-bearing reinforced concrete structure. It enhances marketability over conventional load-bearing wall systems and enables diverse spatial designs tailored to residents' preferences and daily lives.
Also, at the seminar GS Engineering and Construction presented OSC construction technology and the current status in addition to new floor plans for PC multiunit dwellings. Pursuing prefabricated building (Prefab) initiatives most aggressively in the industry, GS Engineering and Construction will share research results in collaboration with public institutions and the Korea Association of Structural Engineers and continue discussions to expand the PC industry, including improvements to related systems.
GS Engineering and Construction verified shortened construction periods by redesigning all trades for conversion to PC multiunit dwellings using an existing completed complex as a model. By the end of this year, GS Engineering and Construction will finish verifying construction costs versus RC methods for the full-scale market entry of PC-method multiunit dwellings and, starting next year, will move into PC multiunit dwelling projects ordered by public entities such as LH and GH.
During the demonstration tour of a two-story PC multiunit dwelling that followed the seminar, participants directly experienced the precise construction process of the OSC method, quality uniformity, and reduced environmental impact, taking time to validate the construction process and technologies for next-generation PC multiunit dwellings.
