Autonomous CAD for eliminating inefficiencies in plant design
Arent × Chiyoda Corporation
"PlantStream," a joint venture established in 2020 between Chiyoda Corporation, one of Japan's largest plant construction companies, and Arent, utilizes the expertise of skilled designers by thoroughly algorithmizing it, realizing ultra-high-precision "autonomous design" through CAD. Large-scale designs that traditionally take several months can now be compressed into just a few dozen seconds, addressing issues such as construction timelines and costs, as well as significantly reducing the burden on both people and the environment. This innovative initiative overturns the conventional norms of plant engineering. Since 2025, as a subsidiary of Arent, it has been engaged in the development and sale of the 3D CAD software "PlantStream."

WORK FLOW


- 1st PHASE
- Development of a practical, automatic route search system which not only incorporates a wide spectrum of construction site expertise into logic, but also runs at high speed.
- 2nd PHASE
- Addition of design logic and ultra-high-speed capability to the automatic route search, as well as development of parametric automatic design methods that are highly customizable.
- 3rd PHASE
- Quality improvement of overall functions including UI and UX, as well as development of a data translation function for the downstream CAD.
