Method of construction that does not stop factory operations" Naruse Steel Industry Co., Ltd. "Separate Method
The "Separate Construction Method" is a technique that allows for rebuilding without completely demolishing existing buildings. It divides the construction period into two phases, enabling reconstruction while maintaining operations even in densely populated areas where expanding the construction space is not possible. In this construction plan, we received a request to switch from the old large furnace to the new one without stopping the operation, which is the lifeline of the plating factory. Therefore, we installed a new large furnace on the phase one construction side to take over operations from the old furnace. Additionally, to avoid waste during future factory expansions, the building on the phase two construction side is designed to be suspended from the structural framework of the phase one construction side. This also contributes to reducing the factory's life cycle costs. 【Construction Targets】 ■ There is relocation space on adjacent land. ■ There is no room around the existing building. ■ It is possible to plan production lines across different floors. *For more details, please refer to the PDF document or feel free to contact us.

Company information
Yoshizawa Architectural Structural Design Co., Ltd. is a comprehensive design office that consistently handles everything from planning and design to construction and after-service for factory rebuilding and renewal in-house. There are various reasons for wanting to renew an aging factory or introduce new equipment, but the current situation is fraught with challenges, such as the inability to stop production, the costs associated with relocating to a temporary factory, and the resulting decrease in productivity. Our company employs methods like "Cover Build," which involves constructing a steel frame over the existing factory while keeping production equipment in place, and "Separate," which divides the construction period into phases (e.g., Phase 1 and Phase 2) to avoid a decline in operational rates during rebuilding. Additionally, to assess the potential damage buildings may incur during an earthquake, we conduct various seismic surveys, including crack investigations, concrete strength assessments, and rebar layout measurements. Based on the survey results, we propose seismic reinforcement plans. We focus on preserving the assets of companies, including buildings, machinery, materials, and products. Furthermore, we ensure the prompt recovery and continuity of operations. Supporting everything from seismic diagnosis to reinforcement comprehensively is what we, "Yoshizawa," are dedicated to.
