A construction method that raises the building without demolishing it. The building remains as it is while the roof height is increased.
We would like to introduce a case where Denki Kogyo Co., Ltd. adopted the "Lift-Up Method." Due to the aging of the existing traveling crane, we received a request for an increase in crane lifting height. In the construction process, we connected the column for the raised portion to the existing column head in a way that enhances strength, and then, using the cover build method, we installed a new roof and walls before dismantling the existing roof from the inside. As a result of this construction, the crane lifting height was increased, allowing for more flexible crane movement, which improved work efficiency. [Case Study] ■ Challenge: Increase in crane lifting height ■ Result: The crane lifting height was increased, allowing for more flexible crane movement, which improved work efficiency. *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.
