While projection mapping has found its niche in the hospitality and entertainment industries, some construction companies in Japan have found a new use for the AV tech. A report by Japanese broadcasting corporation NHK showcases the use of projection mapping by Japanese firms Taisei and Maeda to simplify construction projects and improve safety.
Typically, specialists such as electricians are brought on board to read blueprints and manually mark layouts onto a construction site, designating the placement of wiring or plumbing. Taisei has changed things up by utilizing projection mapping technology to project blueprints onto the site instead, meaning workers simply have to trace the markings. According to Taisei, this method has lowered the time it takes to complete the task, and has the advantage of not requiring specialists.
“The greatest merit is that anyone can do the job. We’re working to improve it and to get it adopted at other construction sites,” says Taisei’s Ohkawa Hiroshi.

Maeda, on the other hand, is developing a method that utilizes projection mapping to measure the area and ground level of tunnel excavation projects. Traditionally, this process would require workers to get within close proximity of heavy machinery, increasing the chances of a potential workplace accident. By using the projection mapping process, a laser is used for measuring, and different colors are projected onto different areas that correspond with measurements, keeping workers out of harm’s way.
“Our mission is to remove as much risk as possible and to create a safe working environment by means of mechanisation, information and communication technologies, and automation,” comments Maeda’s Haruta Katsuki.
