Construction method 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. Instead of new construction after total demolition, it divides the construction period into two phases, enabling the replacement to be carried out while maintaining operations even in densely populated areas where expanding the building space is not possible. In this construction plan, based on the request to switch from the old large furnace to the new one without stopping the operation of the large furnace, a new large furnace was established on the first phase construction side to take over operations from the old large furnace. Additionally, to avoid waste during future factory expansions, the building on the second phase construction side is designed to be suspended from the structural framework of the first phase 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 the production line across upper and lower 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-sales 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 that production cannot be halted, and moving to a temporary factory incurs costs, leading to a decrease in productivity, among other challenges. Our company avoids a decline in operational rates associated with rebuilding by using methods such as "Cover Build," which involves constructing steel frames over the existing factory while keeping the production equipment in place, and "Separate," which divides the construction period into phases like Phase 1 and Phase 2. Additionally, to understand the potential damage a building may suffer 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 support the preservation of a company's assets, including buildings, machinery, materials, and products. Furthermore, we ensure the prompt recovery and continuity of operations. Our goal at "Yoshizawa" is to provide total support from seismic diagnosis to reinforcement.
