Daiwa House Cuts Data Center Construction to One Year with Prefab Method

A major Japanese builder has developed a way to construct data centers in half the usual time. Daiwa House Industry Co. announced its new method uses large, factory-built modules. The company constructs entire sections, including walls, floors, and critical cooling systems, in a controlled factory setting. Workers then transport these large prefabricated units to the construction site for rapid assembly. This innovative approach slashes the typical building timeline from two years to just one. The method also reduces on-site labor by approximately 30%, increasing efficiency. The first data center using this technique is already under construction in Osaka. It is scheduled to be fully operational by March 2026. This development responds to soaring global demand for data processing and cloud storage. Faster construction helps companies expand their digital infrastructure more quickly to meet this need.
