Q AR support system for building construction

Hirasawa Lab, Graduate School of Engineering, Chiba University

Structures built using the concept of tensegrity wear a strange appearance. Although the rigid body members bearing the compressive forces are not in contact with each other, the structure itself is lightweight but very strong. Its visual appeal is very attractive, although it is difficult not only to design but also to build. Therefore, it has very rarely been adopted to constructing real buildings.

We have developed a new method, incorporating AR/MR technology, to help with constructing tensegrity structures. During the demonstration, we will show in detail the way to use AR technology in a project for creating a large curved surface composed of coupling several simple tensegrity units together.

There is an important concept in Japanese construction industry called “de-ki-ga-ta management”, which is paired with progress management. “De-ki-ga-ta” management is to check if the building has been constructed as properly as its initial design. By employing AR technology, you can easily compare the current construction site status and the initial design.

AR technology makes it easier for people from an architectural background to adopt tensegrity structures practically, which they would have otherwise given up because of its design and constructional difficulties.
