When a building is damaged due to a major earthquake, the country researches on the cause of failure and tries to find out the weak points and the seismic performance. Using these new knowledge, the Building Standard Act may be revised so as to prevent future damage due to the same disaster.
With that said, due to the revision of the Building Standard Act in May 1981, the current earthquake resistance standard called "New Earthquake Resistance Design Standard" was constructed.
In seismic diagnosis, we check the buildings designed before the "new earthquake-resistant design standard" against the existing standards, whether the shape is easily damaged, or whether degradation due to aging is a problem. We investigate whether there is a place that can become a weak point at the time of a large earthquake and carefully examine the necessity of re-calculating the seismic performance of the building and providing additional reinforcements.

What to keep in mind in Seismic Diagnosis
Maintenance of plants is done on a daily basis. Depending on the result, the range of construction may increase, design drawings may have to be revised, and maintenance procedure and/or methods may be affected. Adherance to the deadline is also important.
As described above, seismic diagnosis influences the entire process and the cost and time will have to be sacrificed. To avoid this, there should be regular communication with everyone, and work schedule must be prepared together.
For unknown and/or inconsistent parts, it is better to visit the site and explain personally to obtain sufficient understanding and to ensure a safe design.
