DeepX, Inc., a startup developing automation technology for construction equipment, has begun providing Oriental Shiraishi with a construction management system. This system has been realized by digital twin technology. It allows remote access from the monitoring room above ground, or even offsite locations, to conduct real-time checks on the measurement results in the underground working room of the pneumatic caisson method.

Challenges on the construction sites

The challenge with the pneumatic caisson method is both the time-limitation for the operation and physical damage to the human operator. These challenges are due to the workroom being located underground with high atmospheric pressure. This means that multiple-hour stays in a decompression chamber were required and the operator could only stay in the workroom for a limited time.
In recent years, due to these factors, the operators mainly worked remotely. However, using remote-control cameras alone comes with the following limitations:
・The site supervisor cannot accurately grasp the overall situation in the workroom.
・Operators cannot get a sense of the distance to the ground, which reduces their efficiency.

Due to these limitations, the operators are still required to enter the workroom at the end of the day and conduct the measurement on site.

Cutting-edge digital twin technology enables advanced construction management


DeepX has developed a real-time and accurate measurement/visualization system for the entire operation in the workroom. It utilizes recognition technology acquired through the development of construction equipment automation technology and has greatly reduced the time constraint and physical burden for the operator at the construction site.

The remote control allows the operator to constantly check the measurement results in the workroom and saves the site supervisor from having to physically enter the workroom every day. The operator can also check the positional relationship between the construction equipment and the ground from a panoramic view, which improves their work efficiency. It is expected that this new system will reduce the time required for site supervisors to prepare reports and prevent miscommunication with other parties involved in the construction process.

Aiming to fully automate the pneumatic caisson construction method

The construction industry has been suffering from a serious labor shortage, and there is an urgent need to improve productivity and reduce the number of on-site workers.
In the future, DeepX’s construction equipment automation technology will be applied with the pneumatic caisson method, aiming to improve productivity and labor-saving efforts by automating the caisson excavator.

 ※World’s first
In-house research. As a result of an Internet survey conducted in October 2022 on a digital twin construction management system that can be operated on-site in the pneumatic caisson construction method, there is no similar solution worldwide, so it is described as the world’s first.
