Factory Reconstruction Method "Separate Method" [Achieving Reconstruction Without Stopping the Line]
Are you giving up on rebuilding a factory because there is no space around the existing building? It is possible to rebuild in two phases without stopping the production line!
The "Separate Construction Method" is a technique where instead of completely demolishing an existing building and then constructing a new one, the construction period is divided into two phases, allowing for the rebuilding to take place while maintaining operations. First, machinery is moved to the second phase side, and construction begins on the first phase side. After the first phase is completed, the machinery is moved back from the second phase side to the first phase side. By completing the second phase afterward, the factory can operate at full capacity without disruption. [Recommended for such factories!] ■ There is relocation space in the adjacent area ■ There is no room around the existing building ■ It is possible to plan the production line across different floors *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Construction Case Study】 Inside the single-story factory that occupied the entire site, there were machine installations that made long-distance movement difficult. Therefore, a three-story building was planned to effectively utilize the space above for the first phase of construction. To ensure that operations could commence with just the completed portion of the first phase, the first and second floors were designed to be used as factory space. The parts that had minimal impact on operations were rebuilt in the first phase, allowing the second phase to be constructed without disrupting operations. In addition to implementing a highly insulated roof to prevent temperature rise and a seismic structure capable of withstanding major earthquakes, the second floor was designed to support a load of 700 kg/m2, resulting in a building with approximately three times the existing area. *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.
