Examples of Utilizing Durability Investigation Services for Long-term Preservation Measures of Structures

[Budget Reduction] Introducing a case where it was decided to implement seismic isolation instead of new construction, confirming a useful life of 50 years in the future.

We would like to introduce a case study of a durability survey conducted during the seismic retrofitting work of a government building. While seismic isolation is low-cost, there were concerns about the durability of the structure, leading to consideration of new construction. It was estimated that even with large-scale repairs repeated over 50 years, the total repair costs would be around several hundred million yen, and thus the decision was made to proceed with seismic isolation rather than new construction. In addition to this, we also present examples of renewal work, long-term use of existing facilities, and assessments of facilities that are 80 years old. 【Case Overview】 ■ Concerns - If the remaining useful life is about 10 years, is the cost-effectiveness justifiable? Should new construction be considered? - New construction costs over 10 billion yen / seismic retrofitting costs 2.3 billion yen ■ Results - Confirmed that there is a useful life of 50 years ahead - Estimated total repair costs over 50 years to be around several hundred million yen *For more details, please refer to the related links or feel free to contact us.
