The system consists of multiple building blocks, each shaped like shipping containers, serving as individual rooms within a larger structure.
The construction of an entire building on-site can be time-consuming and costly. As a result, many companies are turning to prefabricated structures manufactured in factories. A team of experts at the Korea Institute of Civil Engineering and Building Technology, led by Dr. Seok-Ho Lim and Joon-Soo Chung, has enhanced this method by developing a new modular construction system, as reported by New Atlas on December 28.

The system comprises several building blocks resembling shipping containers, functioning as individual rooms in a larger building. Each block consists of two modules: an internal module that includes inner walls, flooring, and ceiling, and a PC module that comprises two load-bearing exterior walls and a load-bearing exterior floor.
Once manufactured, both types of modules are transported to the construction site. Here, a crane will position the internal module into the corresponding PC module, creating a complete unit. Subsequently, the crane continues to lift each block and place it accurately on the concrete foundation, stacking them according to the architectural design. Finally, workers will add the roof, stairs, and corridors to connect the blocks, completing the structure. These blocks account for approximately 70% to 80% of the entire building.
The on-site assembly process is not only less time-consuming and labor-intensive compared to traditional construction methods but also generates less noise, dust, and waste. Moreover, when the building is no longer in use, individual blocks can be dismantled and repurposed for other projects. The Ministry of Land, Infrastructure, and Transport of South Korea recently announced plans to use this system for constructing rental housing in urban areas of Seoul and new towns in the suburbs.
“The modular construction method provides an efficient solution to address environmental issues in the construction industry and the housing shortage. This technology significantly reduces construction costs, minimizes the need for extensive on-site activities, leading to shorter construction times compared to traditional concrete methods,” Lim stated.
