About Us


Shift from "Surveying for construction" to "Surveying for preservation"

I have 30 years of experience in construction surveying. In 1995, this company was established to assist in the recovery from The Great Hanshin-Awaji Earthquake. Thereafter, the number of incidents involving existing infrastructure has increased all over the world.

Therefore, we have decided to focus most of our efforts on the maintenance and management of infrastructure. For this purpose, we have developed breakthrough monitoring technologies under the slogan of “Challenging to measure things that could not be measured”. I believe our advanced technology solves most of our customer’s problems and helps to preserve safety and security.
