A construction method that raises the height without demolishing the building. 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 to increase the crane's lifting height. In the construction process, we connected the columns of the raised portion to the existing column heads to enhance 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's lifting height was increased, allowing for more flexible crane operation, which improved work efficiency. [Case Study] ■ Challenge: Increase crane lifting height ■ Result: The crane's lifting height was increased, allowing for more flexible crane operation, 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-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.
