Disaster Surveys
We conduct independent disaster surveys as a way of contributing to society.
As a team specializing in ground, geological, and topographical technology, we conduct pro bono surveys for disasters such as earthquakes and torrential rains. We make full use of our technical capabilities with the aim of preventing the spread of damage and secondary disasters, and preparing for the future, all free of charge.
