Simply put, we are taking preventive measure
to safeguard infrastructure facilities around the world.

In order to prevent accidents due to aging of
bridges, tunnels and dams over roads and
railways, we conduct collective management
for design, construction, and maintenance
after conducting survey.

Infrastructure facilities age as well as humans.
Just as humans are tested in hospitals, infrastructure
facilities need to be tested to make sure they are in good
working order. If left untouched when repairs are needed,
life-threatening accidents can occur. Also, if an across
the tracks or overpass is dropped, emergency transportation
will be hindered. In order to prevent such a thing from happening,
we maintain and manage it by the latest technology with
connecting our own information and network.

First of all, it is very important to have a
“specialized technician's eye” to accurately grasp
the situation and information. Diagnosis is performed
in this way, and our latest technology is used to detect
and grasp the deformation of the target structure.
The measurement mainly uses optical sensor,
laser Doppler technology, non-destructive diagnosis using
ultrasonic technology, and three-dimensional deformation
analysis using a 3D scanner. We maintain and manage
them by various prescriptions are made using the survey
results. In addition, by full using robot technology,
we can conduct ' survey (Palpation) that can directly
inspect the surface of structures', and it is possible to
conduct more delicate survey remotely.

We can do everything from initial <design> to final
< survey, maintenance and management>. Infrastructure
facility projects require people with diverse expertise and skills,
and the ability to assemble a wide range of information and networks.
In addition, securing and managing such people is also important. If that
part is ambiguous, it will be judgeby the engineer's subjectivity, and in the worst case
an accident will occurafter inspection. Joesei is able to judge and diagnose accurately
by gathering the information of the stable specialist's eyes and various angles, and also
perform construction and management. In addition, we have taken all possible measures
to ensure that we have introduced a wide range of cutting-edge technologies
more than major companies, please leave everything to us.

No. We have introduced our technology not only in Japan,
but in the world such as USA, China, Germany, Vietnam,
and Cambodia.

There are many deteriorated bridges, dams and tunnels
all over the world. At the same time, there are
many risks, so I would like to reduce even one such risk
so that everyone in the world can live in safety and security.
We are also developing the sensors and robots used for the survey,
and we will continue to deliver safety and security to everyone.
