In collaboration with Takasago Thermal Engineering, the leading air conditioning company, we introduce 'PLANETS - Development Codename'. This product digitalizes the entire business process from design, construction, to operation management through the integration of BIM and automation technologies. By coordinating nine SaaS applications around BIM, we achieve remarkable operational efficiency, addressing chronic labor shortages, prolonged working hours, aging craftsmen, delayed DX, low productivity, and rising construction costs. This initiative is a globally unique effort to transform the business processes in the construction industry.

PLANETS is powered by Arent’s advanced automation technology. By automating the labor-intensive input processes (such as modeling) and automatically extracting and utilizing the attribute information from generated BIM models in subsequent design and construction phases, it significantly accelerates the digital transformation (DX) of the entire construction workflow. In the future, leveraging AI with the ‘accumulated knowledge (data)’ will enable further advancements in DX.

PLANETS<br /> (Development Codename)

"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.
In 2025, it became a subsidiary of Arent and was subsequently merged into the company. Since then, it has been responsible for the development and sales of the 3D CAD software “PlantStream.”

Tacit knowledge of construction designers is often described as knack or intuition.
Being ahead of anyone in the world, Arent has unraveled the secrets and developed a technology to turn the tacit knowledge into formulae, enabling high-speed design far exceeding human knowledge.

Arent's client introduction, Established PlantStream Corporation, a joint venture with Chiyoda Corporation, to produce PlantStream . Cleaned up inefficiencies in plant design.

PlantStream

Oftentimes, it is difficult to find your destinations in commercial complexes with multiple floors and many shops.
To solve the issue, we developed a dedicated navigation service for helping you navigate through facilities without hassle.
Combining high-accuracy indoor positioning and voice navigation, it shows you the fastest route to your destination.
You can also check the availability of restrooms and restaurant seat availability information on a real-time basis.
Ever since it was first introduced in a large commercial complex in Nihonbashi, Tokyo as a model project, we have been continuously expanding the coverage areas of the service.

Oftentimes, it is difficult to navigate through large facilities and to find seat availability information.
With the navigation app, you can now easily navigate your way through them and find seat availability information.

Arent Client introduction, Inclusive Navi," a project undertaken with Shimizu Corporation, enables real-time confirmation of access and availability information within a facility.

Inclusive Navi

On conventional two-dimensional maps, it was difficult to dynamically switch the data shown and to show data in a chronological order.
The client needs to conduct disaster preparedness training, but they are unable to do it using realistic images because the training involves a lot of manual work and a significant amount of man-hours. To solve that, we developed a prototype platform in order to coordinate 3D maps and various data and to create a digital twin for the training, recreating the climate conditions.

The challenge was to recreate disaster-affected road conditions.
Its goal is to create a digital twin for disaster-preparedness training by linking 3D maps with various data and by recreating the weather conditions.

Arent's client introduction, NEXCO East, has linked 3D maps with various data to enable real-time understanding of road conditions in the event of a disaster.
