Obayashi-Dam Innovative Construction Technology

Realizing work style reform through construction DX

For a long time, the construction industry has had an image of being “tough, dangerous, dirty,” and with few holidays, leading to a decrease in the number of new recruits. Particularly, dam construction work requires securing a large number of skilled workers due to the large scale of the work, and the shortage of workers is becoming increasingly serious.
Therefore, aiming to improve safety, productivity, and quality management in dam construction projects, Obayashi Corporation has consolidated its construction technology and digital technology accumulated over many years of dam construction into a dam information construction technology called “ODICT (Obayashi-Dam Innovative Construction Technology)”.

Message for Future

Obayashi Corporation will change the future of dams.

Obayashi Corporation will change the future of dams.

In Japan, where there are many natural disasters, the development of infrastructure structures such as dams is essential. However, many challenges such as the aging of skilled workers, labor shortages due to young people leaving the construction industry, and harsh working conditions have pilled up.
We at Obayashi continue to take on challenges to overcome issues. For the future of dam construction, we are nurturing people, creating technology, and moving forward step by step. We will continue to aim for high-quality dam construction that is friendly to workers, local communities, and the environment.

Obayashi Corporation will change the future of dams.
