This is a service that evaluates the seismic resistance of old buildings (those built to outdated seismic standards) and calculates the costs necessary for reinforcement. While a typical seismic diagnosis can cost several million yen, we conduct high-precision analysis using structural diagrams of the building, providing an accurate reinforcement plan while keeping costs down. We also offer consultations regarding cash generation for those struggling with costs related to seismic reinforcement. *For more details, please refer to the PDF document or feel free to contact us.*

The "REdo Diagnosis" service uses a unique diagnostic method to quantify seismic resistance from existing drawings (structural diagrams). It calculates an approximate reinforcement method based on the derived numerical values, as well as the costs associated with reinforcement and the subsidies provided by local governments. The total cost of this service plus the seismic diagnosis remains the same as if the seismic diagnosis were conducted from the beginning, and if transitioning to the seismic diagnosis, that cost will be deducted. Initially, for a small fee, you can understand the current seismic resistance and the details of reinforcement, and calculate the construction costs along with design fees, making it easier to consider financial planning for rebuilding or renovations based on that information. 【For those with concerns】 ■ The cost of diagnosis is high ■ If the diagnosis results in a negative outcome, asset value will decrease ■ There is anxiety about having to include this information in the important matters explanation document ■ There is uncertainty about costs until the completion of construction ■ There is concern about what kind of construction will be involved ■ It is difficult to gain understanding from residents ■ There is a lack of understanding of the overall process *For more details, please refer to the PDF document or feel free to contact us.

• Vibration isolation, vibration control, and earthquake resistance construction

The period (in years) during which the outermost rebar of reinforced concrete structures does not reach carbonation is evaluated as the service life. In the evaluation process, an evaluation report is issued after confirming the investigation details and evaluation results with the Service Life Evaluation Committee. The parts subject to service life evaluation are, in principle, the outdoor sides of shear walls, columns, and beams, where the concrete cover thickness for rebar is stipulated as 30mm in Article 79 of the Enforcement Order of the Building Standards Act. 【Usage Scenarios】 ■ Determining the feasibility of buying or selling existing buildings and large-scale renovation investments, as well as long-term financing decisions related to them ■ Considering significant extensions or decentralization of the replacement timing for aging public facilities ■ Comparing whether to replace or renovate aging condominium buildings ■ Evaluating the profitability of buildings in real estate appraisal and property management ■ Formulating rational renovation plans based on the degree of deterioration, such as the progression of carbonation *For more details, please refer to the PDF document or feel free to contact us.
