DL E&C Develops Total Modular Housing Solution
Assembling the modular homes manufactured in the Busan factory
The Housing Biz Division of DL E&C secured new technologies including bolt-based non-welding connectors for the modular housing total solution and upgraded the productivity and quality of the modular housing project. The developed technology is a method that simultaneously improves productivity and quality through the minimization of welding, concrete pouring, and cement use. The company has developed a bolt-based non-welding connector, deviating from the existing framework welding type of modular manufacture. Even quality and quick and safe manufacturing are possible compared to the existing welding method. The company has adopted the modular construction technology for apartment construction since 2016, and this is the first case of a large construction company developing a total solution including structure manufacture, finish, and facilities related to modular homes. As a result, its technological capability was recognized, with DL E&C winning a 176-modular home construction project in Gurye Jeonnam and Buyeo Dongnam ordered by LH.
In addition to the bolt-based non-welding connector development, the company has developed a dry large panel finishing material replacing bathroom tiles and a unit-type layer piping system. In the foundation and core construction for the modular home’s structural stability, the company uses a simple assembling method of concrete core walls and stairs like Lego blocks produced in a factory by adopting a PC (precast concrete) construction method for staircase to replace the existing concrete pouring or formwork. Consequently, the construction time can be reduced and even quality can be obtained. To ensure the structure’s bearing power, a technology for connecting the pile constructed on the foundation and modular structure and delivering load was developed, enabling omitting the existing concrete foundation baseplate placing work; thus shortening the construction period.
