Introduction backgroundExploring the transformation that digital twins bring to the construction industry

What triggered the inquiry to ArchiTwin

I would like to work more on digital twins, which are virtual copies of real spaces.We were also exploring how digital twins could intertwine with the construction industry.

We had already been experimenting with Matterport internally, but we had ideas like ``I wanted to customize the digital twin'' and ``I wanted to place objects in space,'' but the situation was such that we couldn't put that much effort into development. So, I contacted ArchiTwin.

What led to the introduction of ArchiTwin

A big reason for introducing ArchiTwin was the 2021th anniversary of Azusa Sekkei's founding in 75, so we aimed to appeal to the company through a novel project.

One of them is to create a virtual showroom using a digital twin.We had an idea to press release the product to appeal that we have introduced cutting-edge technology, and to have it featured in a magazine feature (Shinkenchiku).

The reason for introducing it was that we wanted to create an attractive digital twin exhibition hall together with ArchiTwin.

Details of the joint project with ArchiTwin

This project turns Azusa Sekkei's actual office into a virtual space, placing 3D objects, slides, videos, etc., to create a walk-through space that makes you feel as if you are walking around on your own feet.

Azusa Sekkei did the design, and ArchiTwin provided development support using point clouds.This achievement is published in Shinkenchiku (October 2021 separate volume).


When you enter the digital twin space, you can see a concept video of a company called "WE ARE" in front of you.This production, which automatically plays along with lively music, creates an element of surprise as well as a sense of presence.

It is possible to set a theme for each corridor and view the exhibition on the theme on the digital twin.The movement route is free, but it is assumed that it will move in a zigzag to go around the booths one by one, and we have devised points to scan with Matterport so that we can smoothly go to the next booth.In order to create a beautiful space within the limited scanning points, it is important to establish a spatial design and then shoot accordingly.Considering the arrangement of many objects, we used Matterport systematically.

Signboards that can only be seen in the virtual world have a unique way of showing them.Since it is difficult to move the viewpoint with the digital twin, the object is rounded or tilted.When viewed from the back, the panel is reversed like a mirror letter, but in 3D, the data becomes heavy, so I pasted a 2D image.

Also, at the entrance of the passage, set an index where the line is connected in 3D to the information.The concept of the signboard is different between the real and the digital twin, so I was particular about how to show it.

Difficult point

Azusa Sekkei specializes in space design, so I was in charge of designing the virtual space.I worked on adjustments such as how ArchiTwin can display the design beautifully and how to create a comfortable operating environment.

The finish is beautiful, but at the beginning of development, there were issues such as the signboards not being arranged neatly and the white parts not being projected in white.We adjusted the lighting to make the whites look clearer and more vivid, and devised a design and way of doing things that would not feel out of place compared to the surrounding environment.

Also, if the data is large, the server will become heavy, so it was necessary to make fine adjustments such as how much data can be lightened.There was also a plan to automatically play all videos, but since the data becomes heavy, we decided to incorporate streaming playback.It's important for the walkthrough to be able to move smoothly, so we also adjust the image quality so that the panel looks beautiful and the data is light.

There are things that digital twins can and can't do, and we're trying to maximize what we can do.It was not easy to go through trial and error with limited resources to find out how to reach the end users, the customers.

Since every ArchiTwin digital twin is one-of-a-kind, we worked together as a team on this project to meet the needs of customers to the maximum extent possible.

ExampleWhat only ArchiTwin can do that Matterport cannot

ArchiTwin can be used to arrange objects and share information on the construction site with the team.

Even with Matterport alone, 3D 4K data can be saved and shared, but there are limits to its versatility at construction sites. With ArchiTwin, there is a tagging function that allows you to freely arrange objects with no code and leave urgency and comments, making it possible to introduce them to construction sites more practically.

On the ArchiTwin platform, the scope of information sharing can be set arbitrarily, and information can be exchanged with external contractors involved in construction.It is a great solution for construction sites because it can solve the various problems of the corona disaster and improve work efficiency.

In addition, it is a convenient function to display the mini map and see the whole picture like a doll house so that you can see the whole picture.

Future prospectsJoint development with ArchiTwin of a platform that can aggregate architectural information

In the future, we plan to use ArchiTwin for remote construction sites and equipment management, and we are proceeding with the next project.

One of the plans is to create a platform that can aggregate architectural information and incorporate ArchiTwin into it.There is also a plan for ArchiTwin and Azusa Sekkei to jointly develop services linked to the platform.

I would like to continue to utilize the collaboration between the two companies so that we can deliver digital twin solutions and possibilities not only for our company but also for the construction industry as a whole.
